Driving and parking -> Driving systems for Your Mercedes CLA 4 Door First Generation (2013-2018)

For this reason, drive in the following manner in
the event of heavy rain or in conditions in which
aquaplaning can occur:
R
lower your speed
R
avoid tyre ruts
R
avoid sudden steering movements
R
brake carefully
Driving on flooded roads
!
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This
may cause the maximum permissible water
depth to be exceeded.
These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R
in the case of standing water, the water level
must be no higher than the lower edge of the
vehicle body
R
you should drive no faster than walking pace
Winter driving
G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. Do not use
cruise control or Distance Pilot DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Vehicles with manual transmission: shift
to neutral.
X
Vehicles with automatic transmission:
shift the transmission to position N.
X
Try to bring the vehicle under control by using
corrective steering.
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 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.

tion (Y page 312).
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. You must select a
lower gear in good time on long and steep down-
hill gradients, especially if the vehicle is laden or
towing a trailer. On vehicles with automatic
transmission, you need to have selected the
manual drive program M (Y page 150). By doing
so, you will make use of the braking effect of the
162
Driving systems
Driving and parking
engine. This relieves the load on the brake sys-
tem 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 30 km/h and the technically
permitted maximum speed of the vehicle. If the
set value of the permanent limiter is lower, then
this value applies (Y page 166).
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining 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 road, weather or traffic
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 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 smooth or slippery roads. Braking or accel-
erating can 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 a new driver takes over, advise the new driver
of the speed stored.

Speed limiter
General notes
The limiter restricts the speed of the vehicle. The
limiter brakes automatically in order to adjust
the vehicle's speed to the stored speed.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. On vehi-
cles with automatic transmission, you need to
have selected the manual drive program
M (Y page 150). By doing so, you will make use
of the braking effect of the engine. This relieves
the load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
R
Variable for maximum permissible speeds,
e.g. in built-up areas
R
Permanent for a technically permitted max-
imum vehicle speed, e.g. when driving with
winter tyres fitted (Y page 166)
i
The speed indicated in the speedometer
may differ slightly from the stored maximum
permissible speed.

WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the
vehicle could decelerate unexpectedly. There
is a risk of an accident.

selected.
Vehicles with manual transmission: the lim-
iter switches off if you shift to a higher gear and
as a result, the engine speed is too low.
i
The last speed stored is cleared when you
switch off the engine.
Permanent limiter
If you wish to restrict the maximum speed of the
vehicle for an extended period (e.g. when driving
with winter tyres), the desired maximum speed
can be set with the permanent limiter.
You can use the on-board computer to limit the
speed to a value between 160 km/h and
240 km/h (Y page 211).
Shortly before the stored speed is reached, it
appears in the multifunction display. When you
confirm the message with a or %, the
display is suppressed until you next switch off
the engine. The speed will only be displayed
again once the engine has been restarted.
The permanent limiter remains active even if the
variable limiter is deactivated. The driven speed
will remain below the stored speed even in the
event of kickdown.

Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. The sys-
tem detects vehicles using the radar sensor sys-
tem. Distance Pilot DISTRONIC brakes automat-
ically to avoid exceeding the set speed or to
maintain the designated distance from the vehi-
cle in front.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately
to increase the distance to the vehicle in front,
or take evasive action, provided it is safe to do
so.
Distance Pilot DISTRONIC operates in the range
between 0 km/h and 200 km/h.
Shift into a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Important safety notes
G
WARNING
Distance Pilot DISTRONIC does not recognise
R
people or animals
R
stationary objects on the road, e.g. stopped
or parked vehicles
R
oncoming vehicles or crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G
WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
R
give an unnecessary warning and then
brake the vehicle
R
neither give a warning nor intervene
R
accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
G
WARNING
Distance Pilot DISTRONIC brakes your vehicle
with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
!
When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
R
when towing away
R
in a car wash
If you fail to adapt your driving style, Distance
Pilot DISTRONIC can neither reduce the risk of
an accident nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC 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 lane.
Driving systems

Driving and parking
Z
Do not use Distance Pilot DISTRONIC:
R
in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R
on smooth or slippery roads. Braking or accel-
erating can 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.
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired in the following situations:
R
dirt on the sensors or obscured sensors
R
snow or heavy rain
R
interference by other radar sources
R
strong radar reflections, e.g. in multi-storey
car parks
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, Distance Pilot DISTRONIC may
unexpectedly accelerate to the speed stored.
This speed can:
R
be too high for a filter lane or a slip road
R
be so high on the right lane that you pass
vehicles driving in the left lane
R
be so high in the left lane that you pass vehi-
cles driving in the right lane

G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X
Briefly pull the cruise control lever towards
you ?.
X
Remove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.
Pulling away and driving
X
If you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
X
Briefly pull the cruise control lever towards
you ?.
or
X
If Distance Pilot DISTRONIC is activated:
accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
i
Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the
vehicle is stationary.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+ drive pro-
gram (Mercedes-AMG vehicles only), S
(Y page 148) or the manual drive program
(Y page 150). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the E (C in
Mercedes-AMG vehicles:) drive program, the
vehicle accelerates more gently. This setting is
recommended in stop-start traffic.
Changing lanes
If you want to change to the overtaking lane on
multi-lane roads, Distance Pilot DISTRONIC sup-
ports you if:
R
you are driving faster than 70 km/h
R
Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
Driving systems
169
Driving and parking
Z
R
You switch on the respective turn signal
R
Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i
After a short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
When Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position P if:
R
the driver's seat belt is not fastened and the
driver's door is open
R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
The electric parking brake is applied automati-
cally if Distance Pilot DISTRONIC is active when
the vehicle is stationary and:
R
a system fault occurs
R
the power supply is insufficient
If a fault occurs, the transmission may also shift
to position P automatically.
Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
X
Press the cruise control lever up : for a
higher speed or down ; for a lower speed.
X
Keep the cruise control lever pressed until the
desired speed is reached or press the cruise
control lever repeatedly until the desired
speed is reached.
X
Release the cruise control lever.
The new speed is stored. Distance Pilot
DISTRONIC is activated and adjusts the vehi-
cle's speed to the new speed stored.
X
To adjust the set speed in1 km/hincre-
ments: briefly press the cruise control lever
up : or down A to the pressure point.
The last stored speed increases or decreases
in 1 km/h increments.
X
To adjust the set speed in10 km/hincre-
ments: press the cruise control lever briefly
up : or down A beyond the pressure point.
The last stored speed increases or decreases
in 10 km/h increments.
i
Distance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal. If you
accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting the specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function, you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on the vehicle speed. You
can see this distance in the multifunction dis-
play (Y page 171).
The specified minimum distance can be
changed while Distance Pilot DISTRONIC is
switched on or off.

Tips for driving with Distance Pilot
DISTRONIC
General notes
Pay particular attention in the following traffic
situations:
R
Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles when cornering is limited. Your vehi-
cle may brake unexpectedly or late.
R
Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles driving in
a different lane. The distance to the vehicle in
front will be too short.
R
Other vehicles changing lane: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
R
Narrow vehicles: Distance Pilot DISTRONIC
does not detect the vehicle in front on the
edge of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R
Obstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-

4MATIC, together with ESP
®
, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor over-
ride the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC 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

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 shows you
the distance between your vehicle and an obsta-
cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
!
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.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a lorry or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
!
Fold in the ball coupling if the trailer tow
hitch is not required. Parking Assist
PARKTRONIC measures the minimum detec-
tion range to an obstacle from the bumper,
not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you:
R
switch on the ignition
R
shift the transmission to position D, R or N on
vehicles with automatic transmission
R
release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds.
Vehicles with a trailer tow hitch: Parking
Assist PARKTRONIC is deactivated for the rear
area when you establish the electrical connec-
tion between your vehicle and a trailer.
Range of the sensors
General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R
below the detection range, e.g. persons, ani-
mals or objects
R
above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles

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
and brake application can assist you during
parking and when exiting a parking space. Park-
ing Assist PARKTRONIC is also available
(Y page 177).
i
The active braking application is only avail-
able on vehicles with automatic transmission.
Important safety notes
Parking Pilot is only an aid. It is not a substitute
for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that no
persons, animals or objects are in the manoeu-
vring 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
cause you to collide with other road users.
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 kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
R
in a zone where parking or stopping is pro-
hibited
R
in front of driveways or entrances and exits
R
on unsuitable surfaces
180
Driving systems

Parking tips:
R
on narrow roads, drive as closely as possible
past the parking space
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 Parking Assist
PARKTRONIC warning messages
(Y page 178) during the parking procedure
R
you can intervene in the steering procedure to
correct it at any time. Parking Pilot will then be
cancelled
R
when transporting a load that protrudes from
your vehicle, you should not use Parking Pilot
R
never use Parking Pilot when snow chains are
fitted
R
make sure that the tyre 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 or at right angles 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
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa-
ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
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, tail sections or load-
ing ramps of goods vehicles.
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
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
Further information on the detection range
(Y page 177).
Parking Pilot does not assist you parking in
spaces at right angles to the direction of travel if:
R
two parking spaces are located directly next
to one another
R
the parking space is directly next to a low
obstacle such as a low kerb
R
you forward-park
Parking Pilot does not assist you parking in
spaces parallel or at right angles to the direction
of travel if:
R
the parking space is on a kerb
R
the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R
the area is too small for the vehicle to
manoeuvre into
R
the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer

cle
i
Note that Parking Pilot cannot measure the
length of a parking space if it is at right angles
to the direction of travel. You will need to
judge whether your vehicle will fit in the park-
ing space.
When driving at speeds below 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. Parking Pilot displays only
parking spaces on the front-passenger side as

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. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 15 m
away from 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 kerb. If necessary, you
should abort the parking procedure with Park-
ing Pilot.
R
You can also preselect transmission position
D. The vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early, the park-
ing procedure will be cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space
In order that Parking Pilot can 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 kerb 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 manoeuvred into the parking
space.
R
a manoeuvring distance of at least 1.0 mmust
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 the Park-
ing Pilot

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed 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. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect 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 in the following situations:
R
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 contains potholes
R
in case of strong side winds
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 at a speed
below 60 km/h or above 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 and starts assessing
your tiredness again when you continue your
journey 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

higher. The attention level detected by ATTEN-
TION 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 switched off. The sensitivity selected

In addition to the message shown on the multi-
function display, you will then hear a warning
tone.
X
If necessary, take a break.
X
Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks that allow
for adequate recuperation. If you do not take a
break and ATTENTION ASSIST still detects
increasing lapses in concentration, you will be
warned again after 15 minutes at the earliest.
This will happen only if ATTENTION ASSIST still
detects typical indicators of fatigue or increas-
ing lapses in concentration.
Vehicles with multimedia system COMAND
Online: if a warning is output in the multifunc-
tion display, a service station search is per-
formed in the multimedia system. You can
select a service station and you will then be
navigated to this service station. This function
can be activated and deactivated in the multi-
media system; see Digital Owner's Manual.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted and overtaking restrictions to the
driver in the instrument cluster. Driving onto a
section of road in the wrong direction triggers a
warning. Traffic Sign Assist detects traffic signs
with multifunction camera : attached at the
top of the windscreen. The data and general
traffic regulations stored in the navigation sys-
tem are also used to determine the current
speed limit.
If a traffic sign that is relevant to your vehicle is
passed, the display of the speed limits and over-
taking restrictions is updated.
The display can also be updated without a visible
traffic sign in the following situations:
R
The vehicle changes roads (e.g. motorway
exit or slip road)
R
A village or town boundary that is stored in the
digital map is passed
R
The last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction (speed
limit or overtaking restriction) is passed, the
sign is displayed for five seconds. The currently
applicable traffic regulation continues to be
shown in the assistance graphic display
(Y page 208).
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in
wet conditions).
The traffic signs are only displayed with the
restriction if:
R
The regulation must be observed with the
restriction, or
R
Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail-
able sources, no speed limit is displayed in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display : is shown in the
multifunction display.

Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lanes, you will
also receive a visual and audible warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes
G
WARNING
Blind Spot Assist does not react to vehicles:
R
overtaken too closely on the side, placing
them in the blind spot area
R
when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an
accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, e.g. by cycle racks
or overhanging loads. Following a severe impact
or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Blind Spot Assist
may no longer work properly in such cases.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the following situations:
R
dirt on the sensors or obscured sensors
R
poor visibility, e.g. due to fog, heavy rain or
snow
R
a narrow vehicle travelling in front, e.g. a
motorcycle or a bicycle
R
very wide lanes
R
narrow lanes
R
vehicles not driving in the middle of their lane
R
barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors an area up to 3.0 m
behind your vehicle and directly next to your
vehicle.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
R
warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R
warnings may be interrupted when you are
driving alongside particularly long vehicles,
for example lorries, for a prolonged time

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era : attached at the top of the windscreen.
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave your
lane unintentionally.
This function is available in a speed range
between 60 km/h and 200 km/h.
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration through the steering
wheel for up to 1.5 seconds.
Important safety notes
G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you.

WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. Lane Keeping
Assist 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
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function
in the following situations:
R
Poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R
Glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R
The windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
