Notes on breaking-in a new vehicle
The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.

Important safety notes
G
WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
G
WARNING
Unsuitable footwear can hinder correct usage
of the pedals, e.g.:
R
shoes with thick soles
R
shoes with high heels
R
slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R
overheat and cause a fire
R
lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!
Before driving away, you must ensure that,
for your own safety and to avoid damage, the
charging cable has been removed from the
vehicle socket. Otherwise, you cannot shift
the transmission out of position P.
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R
when the condition of charge of the high-volt-
age battery increases
R
if the high-voltage battery is not yet at a nor-
mal operating temperature
R
when driving close to the maximum speed
R
when the vehicle is almost stationary
R
in transmission position N
R
during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be
sufficient. If necessary, counteract the reduced
regenerative braking effect by applying the
brake yourself.
Before commencing your journey, ensure that
the charging cable required for charging the
high-voltage battery is in the vehicle.

General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and a detachable Start/Stop but-
ton.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the drive system.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the drive system starts
immediately.
To start the vehicle without actively using the
SmartKey:
R
the Start/Stop button must be inserted in the
ignition lock.
R
the SmartKey must be in the vehicle.
R
the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 66)
Do not keep the KEYLESS-GO key:
R
with electronic devices, e.g. a mobile phone
or another SmartKey.
R
with metallic objects, e.g. coins or metal foil.
R
inside metallic objects, e.g. a metal case
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after a short time:
R
you will not be able to switch on the ignition
with the Start/Stop button.
R
you will no longer be able to start the drive
system with the Start/Stop button until the
vehicle is unlocked again
If you lock the vehicle centrally using the button
on the front door (Y page 72), you can continue
to start the drive system with the Start/Stop
button.
The drive system can be switched off while the
vehicle is in motion by pressing and holding the
Start/Stop button for three seconds.

WARNING
If children are left unsupervised in the vehicle,
they could:
R
open the doors, thus endangering other
people or road users.
R
get out and disrupt traffic.
R
operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R
release the parking brake.
R
shift the transmission out of park position P
R
start the vehicle's drive system.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This can happen, for example, when
you are parking and your vehicle is not seen by
other road users. This requires you to adopt a
particularly anticipatory driving style, as it is
necessary to allow for the possibility that other
road users may behave erratically.
The vehicle is equipped with a sound generator.
The sound generator is activated so that other
road users can hear your vehicle better. The
sound generator is activated at speeds of under
20 mph (30 km/h) and switches off automati-
cally at higher speeds.
Starting procedure with the Start/Stop
button
The Start/Stop button can be used to start the
vehicle manually without inserting the SmartKey
into the ignition lock. The Start/Stop button
must be inserted in the ignition lock and the
SmartKey must be in the vehicle.

matically. If the brake pedal is not depressed,
the DIRECT SELECT lever can still be moved but
the parking lock remains engaged.
Make sure that no charging cable is plugged in.
The parking lock cannot be released if a charg-
ing cable is plugged in.
Hill start assist
Hill start assist will aid you when pulling away on
a hill. It holds the vehicle for a short time after
you have removed your foot from the brake
pedal. This gives you enough time to move your
foot from the brake pedal to the accelerator
pedal and depress it before the vehicle begins to
roll.
G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:

Maximum acceleration is available for a limi-
ted time.
Rocking the vehicle free
Shifting the transmission repeatedly between
gears D and R may help to free the vehicle if it
has become stuck in slush or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when
shifting back and forth. To shift back and forth
between transmission positions D and R, move
the DIRECT SELECT lever up and down past the

Steering wheel paddle shifters
Manually adjustable recuperation
:
Left-hand steering wheel paddle shifter -
;
Right-hand steering wheel paddle shifter +
You can increase or reduce recuperation in over-
run mode using the steering wheel paddle shift-
ers. When you remove your foot from the accel-
erator pedal, recuperation occurs. The electric
motor is then used as a alternator and energy is
recovered while driving. The recuperated elec-
trical energy is stored in the high-voltage bat-
tery. A higher energy recuperation level means
that the vehicle is braked more powerfully.
If necessary, counteract the reduced regenera-
tive braking effect by applying the brake your-
self.
Information on the Recuperative Braking Sys-
tem (Y page 64).
X
To decrease recuperation: pull right-hand
steering wheel paddle shifter ;.
X
To increase recuperation: pull left-hand
steering wheel paddle shifter :.
The various recuperation levels are shown in the
transmission position display once D has been
selected (Y page 112).
The following recuperation levels are available in
overrun mode:
R
no recuperation (D
+
, coasting mode)
R
moderate recuperation (D)
R
high recuperation (D
-
)
R
recuperation depending on the traffic situa-
tion (D
AUTO
, radar-based)
You can see the intensity of recuperation in
overrun mode by reading the recuperation per-
formance value shown in the power display
(Y page 153).
Every time drive position D is selected, the
transmission switches into recuperation level
D
AUTO
automatically.
The various different levels are to be used under
the following conditions:
D
+
Driving without much braking and
without the presence of obstacles
or sharp bends
The vehicle retains the maximum
possible amount of kinetic
energy.
D
Normal driving
D
-
Sporty driving or driving on a
downhill gradient
The brake pedal does not need to
be used as often because the
extent of the deceleration is
greater than in D.
Energy use when decelerating is
considerably higher than when
the vehicle is braked with the
brake pedal.
D
AUTO
(radar-
based)
The intensity of recuperation is
automatically adjusted to the cur-
rent traffic situation.

led in an infinitely variable manner using the
accelerator pedal.

The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R
when the condition of charge of the high-volt-
age battery increases
R
if the high-voltage battery is not yet at a nor-
mal operating temperature
R
when driving close to the vehicle's maximum
design speed
R
when the vehicle is almost stationary
R
in transmission position N
R
during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be
sufficient. If necessary, counteract the reduced
regenerative braking effect by applying the
brake yourself.
Radar-based recuperation
The vehicle uses the Active Brake Assist sensors
during radar-based recuperation (D
AUTO
). The
sensors detect the distance to the vehicle ahead
and its speed. The intensity of recuperation is
then automatically adjusted to the current traf-
fic situation.
The range can then be increased by storing
energy efficiently. Adjustment is infinitely vari-
able from overrun mode (no recuperation) to
maximum recuperation.
Maintain sufficient distance to the vehicle in
front. Mercedes-Benz recommends that you
activate Active Brake Assist as a visual and
acoustic aid.
Examples of radar-based recuperation:
R
Approaching a slower vehicle, a decelerating
vehicle or when following a vehicle downhill.
Your vehicle decelerates slightly and increa-
ses recuperation.
R
Driving when no vehicle is detected in front or
when a vehicle is detected in the far distance
or an accelerating vehicle is detected. Your
vehicle switches to overrun mode at higher
speeds.
R
Driving on a steep downhill slope. Accelera-
tion downhill is reduced and recuperation is
increased. This is comparable with shifting
down when driving downhill.
X
To activate radar-based recuperation: pull
steering wheel paddle shifter : or ;
towards you and hold for about one second.
X
To deactivate radar-based recuperation:
briefly pull steering wheel paddle shifter :
or ; towards you.
If you change between radar-based and manual
recuperation, the following levels are activated
depending on the selection via the steering
wheel paddle shifters:
: Steering wheel
paddle shifter -
selects D
-
(maximum
recuperation)
; Steering wheel
paddle shifter +
selects D
+
(overrun)
In particular, the function of the radar sensors
can be impaired in the case of:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for exam-
ple in parking garages
R
a narrow vehicle is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the vehicle,
have the radar sensor settings and operation
checked at a qualified specialist workshop
immediately. This also applies to collisions at
slow speeds where there is no visible damage to
the front of the vehicle.
If the radar sensors are not available, the system
switches automatically to level D with moderate
recuperation. Have the radar sensors checked
at a qualified specialist workshop immediately.
Automatic adjustment of recuperation
on downhill gradients
The vehicle can detect steep downhill gradients.
To reduce acceleration downhill and to charge
the high-voltage battery, recuperation is
increased steplessly. This is comparable to the
engine brake in a combustion engine when you
downshift a gear on a downhill gradient.
Automatic adjustment of recuperation on down-
hill gradients is available in level D
AUTO
or on
116
Transmission
Driving and parking
vehicles without steering wheel paddle shifters
in level D.
Intelligent recuperation
During radar-based recuperation (D
AUTO
), the
vehicle uses the map and camera data of Traffic
Sign Assist in addition to the Active Brake Assist
sensors. The rate of recuperation is then auto-
matically adjusted to the current traffic situa-
tion, taking the current and future maximum
speed into account.

outlet. Otherwise, this could result in a poor
contact with the electrical outlet and malfunc-
tions when charging the vehicle.
To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
R
Never lift or carry the controls by the charging
cable connector or the mains plug.
R
To transport the charging cable, the coiled
part can be:
-
wrapped around the controls or
-
secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector
Pay attention to the important safety notes
(Y page 117).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting values, provided that:
R
the power supply and the charging cable are
not damaged
R
the instructions for handling the charging
cable and controls on the charging cable are
observed
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Electrical fuse against overvoltage
!
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from
voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
electrical fuse against overvoltage has been
tripped. Otherwise, the charging process cannot
be continued. The high-voltage battery will not
be charged and you may not be able to drive the
vehicle.
If other devices are protected by the same pro-
tective device, these are switched off as well
when the protective device is triggered. Ensure
that these other devices are still operational
after reactivating the protection device.

warranty documentation and in the related
Maintenance Booklet
R
maintenance notes for the high-voltage bat-
tery in the Maintenance Booklet
Method of operation
The vehicle is equipped with a high-voltage bat-
tery for driving. The high-voltage battery stores
the energy needed to operate the electric motor
and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pulling
away, accelerating and during the journey.
In overrun mode (except D+), kinetic energy is
converted by means of energy recuperation into
electrical energy and stored in the high-voltage
battery.
The high-voltage battery can be charged as fol-
lows:
R
through energy recuperation while the vehicle
is in motion
R
with the charging cable at a mains socket
while the vehicle is stationary
R
with the charging cable at a charging station
while the vehicle is stationary
The high-voltage battery can be charged using a
single-phase charging cable in a voltage range
from 100 V to 240 V.
If the condition of charge drops to less than 13%,
the high-voltage battery reserve indicator lamp
lights up in the instrument cluster. Charge the
high-voltage battery as soon as possible.
Below a condition of charge of 5%, the perform-
ance of the vehicle is reduced. The vehicle's
high-voltage electrical system switches off at a
condition of charge of 0%.
Use of the pre-entry climate control function
may mean that the high-voltage battery is not
fully charged.
High and low outside temperatures
Low outside temperatures
The efficiency of the high-voltage battery is sig-
nificantly reduced at very low outside tempera-
tures. The high-voltage battery is then no longer
able to provide the normal electrical power out-
put.
High outside temperatures
To prevent damage to the high-voltage battery
due to very high outside temperatures, the max-
imum power output of the high-voltage battery
is reduced automatically.
The E-CELL display indicates the maximum
amount of power available (Y page 152).
Notes on battery care
Avoid storing or transporting the vehicle in high
temperatures over a long period (e.g. container
transport).
If you park the vehicle and leave it stationary for
longer periods, connect it to a power supply.
Temperatures below Ò13 ‡ (Ò25 †) and over
104 ‡ (40 †), which affect the vehicle for a
period of more than seven days, can cause irre-
versible damage.
Discharged battery
The vehicle's high-voltage electrical system
switches off if the high-voltage battery is com-
pletely discharged. 30 seconds prior to this, you
are informed of the switch-off by the
BatteryBattery
Level
Level TooToo Low.Low. StopStop andand ChargeCharge Immedi‐Immedi‐
atelyately message. This protects the battery from
exhaustive discharge.
It is not possible to restart the drive system until
after charging.
Do not leave the vehicle parked for longer than
14 days with a high-voltage battery condition of
charge below 20%.
You can check the condition of charge in the
charge level display (Y page 153).
Further information on the "Energy flow display"
can be found in the "Trip" menu (Y page 157).

Energy consumption and range
This range is reduced by:
R
high and low outside temperatures
R
a non-anticipatory driving style
R
switching on consumers, e.g. air-conditioning
system or heating
The battery's physical characteristics are such
that leaving the vehicle parked for an extended
period at low outdoor temperatures without
charging it can lead to:
R
a reduction in battery performance
R
longer charge times
In extreme cases, this could mean that the vehi-
cle cannot be started. For this reason, connect
the charging cable when leaving the vehicle
parked for long periods at low outdoor temper-
atures.
As a result of its basic characteristics, the
amount of energy available from the high-volt-
age battery decreases over the course of its life.
This reduces:
R
the maximum range that can be achieved by
the vehicle
R
the maximum output (acceleration) of the
vehicle
You can actively reduce the energy consump-
tion of your vehicle in a number of ways, for
example, by:
R
an anticipatory driving style
R
reducing the use of electrical consumers
R
having the vehicle regularly maintained
The charging time of the high-voltage battery
may change over the course of its life.
Observe the displays on energy usage
(Y page 158) and range (Y page 158).
RANGE PLUS
If you activate RANGE PLUS, the operating win-
dow of the battery will be extended at the next
charging process. An extended driving range will
be available to you for the next journey.
Using RANGE PLUS shortens the service life of
the battery. Therefore, only use RANGE PLUS if,
for example:
R
long journeys are planned or
R
the availability of charging stations at the des-
tination is limited
The more often RANGE PLUS is used, the more
the extended range is reduced.
Therefore always check the range display before
every journey (Y page 158).

Charging cable
Important safety notes
!
Only use the charging cable to charge the
high-voltage battery. Do not use the charging
cable for other purposes. It may otherwise be
damaged.
The vehicle is supplied with a single-phase 12 A
charging cable. Only use the charging cable
included with the vehicle, which has been
approved for vehicle use.
Pay attention to the "Important safety notes"
(Y page 117).
If you use the supplied 12 A charging cable to
charge a high-voltage battery:
R
the charge time increases considerably
R
electrical consumption increases considera-
bly
Where possible, charge the high-voltage battery
at a charging station (Y page 125). Only then
can certified electrical energy consumption lev-
els be reached.
i
The charging process can vary depending on
the charging station. Therefore, always
observe the local information.
Stowing the charging cable

Setting the maximum charge current
G
WARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
!
An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
You can set a limit for the values of the charge
current used in charging the high-voltage bat-
tery. This acts as a means of preventing the
power supply from overloading. You can set this
limit by using the controls on the charging cable
or in the on-board computer's menu. Only set
the maximum charge current in the on-board
computer menu if there are no charge current
settings on the charging cable.
The default standard value is the minimum
charge current setting. This corresponds to the
minimum available charge current from the
power supply.
i
The value of the maximum setting and the
relevant adjustment values may vary depend-
ing on the country.
Before charging the high-voltage battery, have
the maximum permissible charge current for the

Mercedes Electric - Vehicle Homepage"
The "My Mercedes Electric - Vehicle Homepage"
allows you access to information about your
vehicle and its functions using remote query and
remote configuration. For example, climate con-
trol can be activated using remote configuration
which means that it need not be set in the vehi-
cle. Power for the climate control is primarily
supplied via the charging cable connected to the
mains supply. In most cases, this does not
reduce the range. If climate control is activated,
the condition of charge and thus the range may
be reduced. The "Vehicle Homepage" provides
you with information all about how to use your
vehicle.
If the vehicle is entered in your personal area of
the "Vehicle Homepage", you can also access
the following functions:
R
request the current condition of charge of the

Important safety notes
G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
G
WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while
driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m) per sec-
ond.

Observe the following tips to save energy:
R
The tires should always be inflated to the rec-
ommended tire pressure.
R
Remove unnecessary loads.
R
Remove roof racks when they are not needed.
R
Avoid frequent acceleration or braking.
Energy consumption also increases when driv-
ing in low or high outside temperatures, in stop-
start traffic, on short journeys and in hilly ter-
rain.
Drinking and driving
G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or

Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you
in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Your driving style can significantly influ-
ence the vehicle's consumption.

Coasting (evaluation of all decelera-
tion processes):
R
the outer area fills up and the inner

The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the
driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas

are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel
consumption. The additionally achieved range
displayed under
Bonus fr. StartBonus fr. Start does not
indicate a fixed consumption reduction.
In addition to driving style, the actual consump-
tion is affected by other factors, such as:
R
Load
R
Tire pressure
R
Cold start
R
Choice of route
R
Active electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
To achieve a higher value in the categories
"Acceleration" and "Constant", drive the vehicle
in drive program E+ or E.
On long journeys at a constant speed, e.g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform a manual rest
(Y page 158).
For more information on the ECO display, see
(Y page 156).
Braking
Important safety notes
G
WARNING
If you increase the recuperation level on slip-
pery road surfaces, the drive wheels may lose
their traction. There is an increased danger of
skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces.
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R
when the condition of charge of the high-volt-
age battery increases
R
if the high-voltage battery is not yet at a nor-
mal operating temperature
R
when driving close to the maximum speed
R
when the vehicle is almost stationary
R
in transmission position N
R
during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be
sufficient. If necessary, counteract the reduced
regenerative braking effect by applying the
brake yourself.
Downhill gradients
On long, steep gradients, you must reduce the
load on the brakes by selecting maximum recu-
peration. This helps you to avoid overheating the
brakes and wearing them out excessively.
Recuperation allows the vehicle to be deceler-
ated without placing a load on the braking sys-
tem.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Heavy and light loads
G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. This allows the airflow to
cool the brakes more quickly.
Driving tips
133
Driving and parking
Z
Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
R
In order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
R
Carefully depress the brake pedal and the
beginning and end of a journey.
R
Maintain a greater distance to the vehicle
ahead.
Servicing the brakes
!
The brake fluid level may be too low, if:
R
if the red brake warning lamp lights up in
the instrument cluster and
R
you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
!
A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe-
cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.
!
As the ESP
®
system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position 0 or 1 in
the ignition lock) if:
R
the electric parking brake is tested on a
brake dynamometer (for a maximum of
ten seconds)
R
the vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP
®
may
seriously damage the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.
You can find a description of Brake Assist (BAS)
on (Y page 59).
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
Checking brake lining thickness
You can measure the break pad/lining thick-
ness using a test gage. Color-coding (green or
red) on the test gage allows you to determine
whether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box.

Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
R
you drive at low speeds
R
the tires have adequate tread depth
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
R
lower your speed
R
avoid ruts
R
avoid sudden steering movements
R
brake carefully
Driving on flooded roads
!
Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.

their traction. There is an increased danger of
skidding and accidents.
Do not increase the recuperation level on slip-
pery road surfaces.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Shift the DIRECT SELECT lever to position N.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Driving systems
Cruise control
General notes
Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. Change into transmis-
sion position D
-
(Y page 115) on long and steep
downhill gradients. This increases recuperation
in overrun mode. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 20 mph (30 km/h) and the tech-
nically permitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady
speed for a prolonged period.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for braking in
good time and for staying in your lane.
Do not use cruise control:
R
in road and traffic conditions which do not
allow you to maintain a constant speed e.g. in
heavy traffic or on winding roads
R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R
in poor visibility, e.g. due to fog, heavy rain or
snow
If there is a change of drivers, advise the new
driver of the speed stored.

Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting a parking space. When maneuvering,
parking or pulling out of a parking space, make
sure that there are no persons, animals or
objects in the area in which you are maneuver-
ing.
!
When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.

Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
can assist you during maneuvering and parking.
Parking Assist PARKTRONIC is also available
(Y page 139).
Important safety notes
Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Make sure that no persons, animals or
objects are in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot
parking procedure.
!
If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
R
where parking or stopping is prohibited
R
in front of driveways or entrances and exits
R
on unsuitable surfaces
Parking tips:
R
On narrow roads, drive as close to the parking
space as possible.
R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly.
R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R
Pay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (Y page 140).
R
You can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled.
R
When transporting a load that protrudes from
your vehicle, you must not use Parking Pilot.
R
Never use Parking Pilot when snow chains are
mounted.
R
Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are:
R
parallel to the direction of travel
R
on straight roads, not bends
R
on the same level as the road, e.g. not on the
pavement
Detecting parking spaces
Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, truck overhangs or
loading ramps.
G
WARNING
If there are objects above the detection range:
R
Parking Pilot may steer in too early
R
the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
For further information on the detection range
(Y page 139).
Parking Pilot does not assist you parking in
spaces parallel to the direction of travel if:
R
the parking space is on a curb
R
the parking space is apparently blocked, for
example by foliage or grass paving blocks

Parking Pilot is activated automatically when
driving forwards. The system is operational at
speeds of up to approximately 22 mph
(35 km/h). While in operation, the system inde-
pendently locates and measures parking spaces
on both sides of the vehicle.
Parking Pilot will only detect parking spaces:
R
parallel to the direction of travel
R
that are at least 59 in (1.5 m) wide
R
that are at least 51 in (1.3 m) longer than your
vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol ; as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. Park-
ing Pilot only displays parking spaces on the
front-passenger side as standard. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain activated until you confirm the
use of Parking Pilot by pressing the a button
on the multifunction steering wheel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.

Parking tips:
R
The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Parking Pilot guides you
too far into a parking space, or not far enough
into it. In some cases, it may also lead you
across or onto the curb. If necessary, you
should abort the parking procedure with Park-
ing Pilot.
R
You can also select preselect transmission
position D. The vehicle redirects and does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. A sensi-
ble parking position can no longer be ach-
ieved from this position.
Exiting a parking space
In order for Parking Pilot to support you when
exiting the parking space:
R
you need to have parked using Parking Pilot.
R
the border of the parking space must be high
enough at the front and the rear. A curb stone
is too small, for example.
R
the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvered into the parking
space.
R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using Parking
Pilot.

monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
148
Driving systems
Driving and parking
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid to the driver. It
might not always recognize fatigue or increasing
inattentiveness in time or fail to recognize them
at all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all:
R
if the length of the journey is less than approx-
imately 30 minutes
R
if the road condition is poor, e.g. if the surface
is uneven or if there are potholes
R
if there is a strong side wind
R
if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R
if you are predominantly driving slower than
37 mph (60 km/h) or faster than 125 mph
(200 km/h)
R
if the time has been set incorrectly
R
in active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset when you continue
your journey and starts assessing your tiredness
again if:
R
you switch off the engine
R
you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
You can have current status information dis-
played in the assistance menu (Y page 162) of

SensitiveSensitive selected: the sensitivity is set
higher. The attention level detected by Attention
Assist is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated (stand-
ard/sensitive).
