DrDriving and driving and driving safeiving safety syty syststemsems

DrDriving systiving systems and yems and your rour responsibilityesponsibility

Your vehicle is equipped with driving systems

which assist you in driving, parking and maneuver-

ing the vehicle. The driving systems are only aids.

They are not a substitute for your attention to the

surroundings and do not relieve you of your

responsibility pertaining to road trac law. The

driver is always responsible for maintaining a safe

distance to the vehicle in front, for vehicle speed,

for braking in good time and for staying in lane.

Pay attention to the trac conditions at all times

and intervene when necessary. Be aware of the

limitations regarding the safe use of these sys-

tems.

Driving systems can neither reduce the risk of

accident if you fail to adapt your driving style nor

override the laws of physics. They cannot always

take into account road, weather or trac condi-

tions.

InfInforormation on vmation on vehicle sensorehicle sensors and camers and camerasas

Some driving and driving safety systems use cam-

eras as well as radar or ultrasonic sensors to

monitor the area in front of, behind or next to the

vehicle.

Multifunction camera

Cameras in the outside mirrors

Front radar

Front camera

Corner radars

Ultrasonic sensors

Rear view camera

WARNINGARNING Risk of accident due to restric-

ted detection performance of vehicle sen-

sors and cameras

If the area around vehicle sensors or cameras

is covered, damaged or dirty, certain driving

and safety systems cannot function correctly.

There is a risk of an accident.

Keep the area around vehicle sensors or

cameras clear of any obstructions and

clean.

Have damage to the bumper, radiator

grille or stone chipping in the area of the

front and rear windows repaired at a

qualied specialist workshop.

Driving and parking

157

Particularly, keep the areas around the sensors

and cameras free of dirt, ice or slush

(/ page 271). The sensors and cameras must

not be covered and the detection ranges around

them must be kept free. Do not attach additional

license plate bracket, advertisements, stickers,

foils or foils to protect against stone chippings in

the detection range of the sensors and cameras.

Make sure that there are no overhanging loads

protruding into the detection range.

If there is damage to a bumper or the radiator

grille, or aer an impact, have the function of the

sensors checked at a qualied specialist work-

shop. Have damage or stone chipping in the area

of the cameras on the front and rear windows

repaired at a qualied specialist workshop.

FFunctions of ABSunctions of ABS

The Anti-lock Brake System (ABS) regulates the

brake pressure in critical driving situations:

During braking, for instance, at maximum full-

stop braking or if there is insucient tire trac-

tion, the wheels are prevented from locking.

Vehicle steerability while braking is ensured.

If ABS intervenes when braking, you will feel a

pulsing in the brake pedal. The pulsating brake

pedal can be an indication of hazardous road con-

ditions and can serve as a reminder to take extra

care while driving.

Syst

System limitsem limits

ABS is active from speeds of approx. 3 mph

(5 km/h).

ABS may be impaired or may not function if a

malfunction has occurred and the yellow !

ABS warning lamp lights up continuously aer

the vehicle is started.

FFunction of Bunction of BASAS

WARNINGARNING Risk of an accident caused by a

malfunction in BAS (Brake Assist System)

If BAS is malfunctioning, the braking distance

in an emergency braking situation is

increased.

Depress the brake pedal with full force in

emergency braking situations. ABS pre-

vents the wheels from locking.

The Brake Assist System (BAS) supports your

emergency braking situation with additional brake

force.

If you depress the brake pedal quickly, BAS is

activated:

BAS automatically boosts the brake pressure.

BAS can shorten the braking distance.

ABS prevents the wheels from locking.

The brakes will function as usual once you release

the brake pedal. BAS is deactivated.

Function of Aunction of Activctive Speed Limit Assiste Speed Limit Assist

If a change in the speed limit of 12 mph

(20 km/h) or more is detected and automatic

adoption of speed limits is activated, the new

speed limit is automatically adopted as the stored

speed (/ page 183).

The driven speed is adjusted when the vehicle is

level with the trac sign at the latest. In the case

of signs indicating entry into an urban area, the

speed is adapted according to the speed permit-

ted within the urban area. The speed limit display

in the Instrument Display is always updated when

the vehicle is level with the trac sign.

If there is no speed restriction on an unlimited

stretch of road (e.g. on a freeway), the recom-

mended speed is automatically adopted as the

stored speed. The system uses the speed stored

on an unlimited stretch of road as the recommen-

ded speed. If you do not alter the stored speed on

an unlimited stretch of road, the recommended

speed is 80 mph (130 km/h).

If Active Distance Assist DISTRONIC has been put

into passive mode by pressing the accelerator

pedal, only speed limits which are higher than the

set speed are adopted.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognize

dangers (/ page 157).

Syst

System limitsem limits

The system limits of Trac Sign Assist apply to

the detection of trac signs (/ page 182).

Speed limits below 12 mph (20 km/h) are not

automatically adopted by the system as the stored

speed. Temporary speed restrictions (e.g. for a

certain time or due to weather conditions) cannot

be properly detected by the system. The maxi-

Driving and parking

171

mum permissible speed applying to a vehicle with

a trailer is not detected by the system.

Adjust the speed in these situations.

WARNINGARNING Risk of accident due to Active

Speed Limit Assist adapting the vehicle's

speed

The speed adopted by Active Speed Limit

Assist may be too high or incorrect in some

individual cases, such as:

at speed limits below 12 mph (20 km/h)

in wet conditions or in fog

when towing a trailer

Ensure that the driven speed complies

with trac regulations.

Adjust the driving speed to suit current

trac and weather conditions.

FFunction of runction of routoute-based speed adapte-based speed adaptationation

When Active Distance Assist DISTRONIC is activa-

ted, the vehicle speed will be adapted accordingly

to the route events ahead. Depending on the drive

program selected, the vehicle negotiates a route

event ahead in an economical, comfortable or

dynamic manner. When the route event has been

passed, the vehicle accelerates again to the

stored speed. The set distance to the vehicle in

front, vehicles detected ahead and speed restric-

tions ahead are taken into account.

You can activate and deactivate route-based

speed adaptation in the multimedia system

(/ page 173).

The following route events are taken into account:

Curves

T-intersections, roundabouts and toll plazas

Turns and exits

Trac jams ahead (only with Live Trac Infor-

mation )

When the toll station is reached, Active Dis-

tance Assist DISTRONIC adopts the speed as

the stored speed.

Also, the speed is reduced if the turn signal indi-

cator to change lanes is switched on and one of

the following situations is detected:

Turning o at intersections

Driving on slowing-down lanes

Driving on lanes adjacent to slowing-down

lanes

The driver is responsible for choosing the right

speed and observing other road users. This

applies in particular to intersections, roundabouts

and trac lights, as route-based speed adaptation

does not brake the vehicle to a standstill.

When route guidance is active, the rst speed

adjustment is carried out automatically. If the turn

signal indicator is switched on, the selected route

is conrmed and further speed adjustment is acti-

vated.

Speed adaptation is canceled in the following

cases:

If the turn signal indicator is switched o

before the route event.

If the driver depresses the accelerator or

brake pedal during the process.

Syst

The speed adaptation made by the system may

not always be suitable, particularly in the following

situations:

The road's course not clearly visible

Road narrowing

Varying maximum permissible speeds in indi-

vidual lanes, for example at toll plazas

Wet road surfaces, snow or ice

In these situations the driver must intervene

accordingly.

Active Steering Assist is only available up to a

speed of 130 mph (210 km/h). The system helps

you to stay in the center of the lane by means of

moderate steering interventions. Depending on

the speed driven, Active Steering Assist uses the

vehicles ahead and lane markings as a reference.

Depending on the country, in the lower speed

range Active Steering Assist can use the sur-

rounding trac as a reference. If necessary,

Active Steering Assist can then also provide

assistance when driving away from the center

of the lane, for example, to form a rescue

Avoid looking at the Instrument Display

and Head-up Display for a long time.

The Instrument Display and Head-up Display (if

Use of the trac light information service

requires the regular transmission of vehicle

positions and driving directions to Mercedes-

Benz. The data is immediately anonymized by

Mercedes-Benz and forwarded to the provider

of the trac light information service. The

vehicle positions and driving directions are

deleted aer a very short time (a few sec-

onds) and are not permanently saved.

If you do not want to transmit the vehicle

positions and driving directions, you have the

following options:

You deactivate the service in the

Mercedes me portal.

You have the service deactivated at an

authorized Mercedes-Benz Center.

You deactivate the service in the

Assis-

tance menu in the multimedia system

(/ page 186).

This trac light information service is only

available in certain cities and regions.

The function is supported under the following con-

ditions:

The vehicle is equipped with a multimedia sys-

tem featuring navigation and a communication

module with an activated, integrated SIM card.

You have a user account for the Mercedes me

Portal.

The vehicle has been connected with the user

account.

The navigation services option is available,

subscribed to and activated in the Mercedes

me Portal.

The trac light data service belongs to the

scope of the navigation services.

The current vehicle position and the direction of

travel are transmitted via the communication

module and aligned with the data from the trac

light data service provider. The provider gathers

data from trac lights which transmit their chang-

ing phases. When the vehicle approaches an inter-

section with networked trac lights, data is trans-

mitted to the vehicle.

A set turn signal le or right and lane recommen-

dations during active route guidance are taken

into account for the display.

The service is for information purposes only and is

not linked to any other vehicle functions, systems

or components. Please note that the displayed

data is not available in all trac areas and may be

incorrect.

Certain light signal systems automatically adapt

their switching times to the current trac situa-

tion. This can lead to a sudden change in the

countdown display.

The information in the Instrument Display is

Function of tunction of the passivhe passive side ime side impact protpact protectionection

Passive side impact protection is an additional

Parking Assist PARKTRONIC function which warns

the driver about obstacles at the side of the vehi-

cle. A warning is issued when obstacles are

detected between the front and rear detection

range. In order for an object on the side to be

detected, the sensors in the front and rear

bumper must rst detect the object while you are

driving past it.

During the parking procedure or maneuvering,

objects are detected as the vehicle drives past. If

you steer in the direction of a detected obstacle

and there is a risk of a lateral collision, a warning

is issued and the segments light up in color on the

display.

The segment color changes depending on the dis-

tance to the detected obstacle:

Yellowellow:: approximately 1.0 - 2.0  (30 - 60 cm)

Red:ed: less than approximately 1.0  (30 cm)

In order for lateral, front or rear segments to be

displayed, the vehicle must rst travel a distance

of at least half a vehicle's length. Once the vehicle

has travelled the length of the vehicle, all of the

lateral front and rear segments can be displayed.

wards up to approximately 22 mph (35 km/h), the

system automatically measures parking spaces on

both sides of the vehicle.

As soon as all requirements are met for searching

for parking spaces, the Ç display appears in

the Instrument Display.

When Active Parking Assist has detected parking

spaces, the È display appears in the Instru-

ment Display. The arrows show on which side of

the road detected parking spaces are located.

They are then shown on the media display.

The parking space can be selected as desired.

Depending on the location of the parking space,

the parking direction (rearwards or forwards) can

also be selected as desired.

When Active Parking Assist is activated, the turn

signal indicators are activated based on the calcu-

lated path of your vehicle.

When you are entering or exiting a parking space,

the procedure is assisted by acceleration, braking,

steering and gear changes.

Active Parking Assist is only an aid. It is not a sub-

stitute for your attention to the surroundings. The

responsibility for safe maneuvering and parking

remains with you. Make sure that no persons, ani-

mals or objects etc. are in the maneuvering

range.

Parking Assist is not available.

Objects located above or below the detection

range of the sensors, e.g. overhanging loads,

overhangs or loading ramps of trucks, or the bor-

ders of parking spaces, are not detected during

measurement of the parking space. These are

also then not taken into account when calculating

the parking procedure. In some circumstances,

Active Parking Assist may therefore guide you into

the parking space incorrectly.

WARNINGARNING Risk of accident due to objects

located above or below the detection

range of Active Parking Assist

If there are objects above or below the detec-

tion range, the following situations may arise:

Active Parking Assist may steer too early.

The vehicle may not stop in front of these

objects.

There is a danger of collision!

In these situations, do not use Active

Parking Assist.

Extreme weather conditions, such as snow or

heavy rain, may lead to a parking space being

measured inaccurately. Parking spaces that are

partially occupied by trailer drawbars might not be

identied as such or be measured incorrectly.

Only use Active Parking Assist on level, high-grip

ground.

Do not use Active Parking Assist in the following

situations:

In extreme weather conditions such as ice,

packed snow or in heavy rain.
