Driving and driving safety systems

Driving systems and your responsibility

Your vehicle is equipped with driving systems that

assist you in driving, parking and maneuvering the

vehicle. The driving systems are only aids. They

are not a substitute for you paying attention to

your 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 an

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.

Some driving systems can regulate or limit the

speed to a previously set value. Draw atten-

tion to the stored speed when changing driv-

ers.

Information on vehicle sensors and cameras

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.

WARNING 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.

Keep the areas around the sensors and cameras

in particular free of dirt, ice and slush

(/ page 326). The sensors and cameras must

not be covered and the detection areas around

them must be kept clear. Do not attach additional

license plate bracket, advertisements, stickers,

wraps or stone chip protection lms in the detec-

tion range of the sensors and cameras. Make sure

that there are no overhanging loads protruding

into the detection area.

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 around the

cameras on the front and rear passenger com-

partment windows repaired at a qualied special-

ist workshop.

Functions 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.

System 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.

Functions of O-road ABS

O-road ABS is specially adapted for driving o-

road:

The front wheels lock cyclically during braking.

The braking distance is shortened due to the

digging-in eect.

System limits

O-road ABS functions at speeds below

25 mph (40 km/h).

If O-road ABS intervenes, the ability to steer

may be restricted.

Function of BAS

WARNING 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.

Driving and parking

161

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.

Functions of ESP

WARNING Risk of skidding if ESP

deactivated

If you deactivate ESP

, ESP

cannot carry out

vehicle stabilization.

ESP

should only be deactivated in the

following situations.

NOTE Mercedes-AMG vehicles

Observe the notes in the Supplement.

You could otherwise fail to recognize

dangers.

The Electronic Stability Program (ESP

) can moni-

tor and improve driving stability and traction in

the following situations within physical limits:

When pulling away on wet or slippery roads.

When braking.

If the vehicle deviates from the direction desired

by the driver, ESP

can stabilize the vehicle by

intervening in the following ways:

One or more wheels are braked.

The engine output is adapted according to the

situation.

ESP

is deactivated if the å ESP

OFF warn-

ing lamp lights up continuously on the instrument

display.

Observe the following points when ESP

is deacti-

vated:

Driving stability will no longer be improved.

The drive wheels could spin.

ETS/4ETS traction control is still active.

When ESP

is deactivated, you are still assis-

ted by ESP

when braking.

If the ÷ ESP

warning lamp ashes on the

instrument display, one or several wheels has

reached its grip limit:

Adapt your driving style to suit the current

road and weather conditions.

Do not deactivate ESP

Only depress the accelerator pedal as far as is

necessary when pulling away.

Deactivate ESP

in the following situations to

improve traction:

When using snow chains.

In deep snow.

On sand or gravel.

162

Driving and parking

Spinning the wheels results in a cutting

action, which enhances traction.

If the ÷ ESP

warning lamp lights up continu-

ously, ESP

is not available due to a malfunction.

Observe the following information:

Indicator and warning lamps (/ page 440)

Display messages (/ page 391)

ETS/4ETS (Electronic Traction System)

ETS/4ETS traction control is part of ESP

and

makes it possible to pull away and accelerate on a

slippery road.

ETS/4ETS can improve the vehicle's traction by

intervening in the following ways:

The drive wheels are braked individually if they

spin.

More drive torque is transferred to the wheel

or wheels with traction.

Inuence of drive programs on ESP

The drive programs enable ESP

to adapt to dif-

ferent weather and road conditions as well as the

driver's preferred driving style. Depending on the

selected drive program, the appropriate ESP

mode will be activated. You can select the drive

programs using the DYNAMIC SELECT switch

(/ page 139).

Function of ESP

Crosswind Assist

ESP

Crosswind Assist detects sudden gusts of

side wind and helps the driver to keep the vehicle

in the lane:

ESP

Crosswind Assist is active at vehicle

speeds between approx. 50 mph (80 km/h)

and 125 mph (200 km/h) when driving

straight ahead or cornering slightly.

The vehicle is stabilized by means of individual

brake application on one side.

Function of ESP

trailer stabilization

WARNING Risk of accident in poor road

and weather conditions

In poor road and weather conditions, the

trailer stabilization cannot prevent lurching of

the vehicle/trailer combination. Trailers with a

high center of gravity may tip over before

ESP

detects this.

Always adapt your driving style to suit

the current road and weather conditions.

When you are driving with a trailer, ESP

can sta-

bilize your vehicle if the trailer begins to swerve

from side to side:

ESP

trailer stabilization will be active at

speeds above 40 mph (65 km/h).

Slight swerving is reduced by means of a tar-

geted, individual brake application on one

side.

In the event of severe swerving, the operating

energy output will also be reduced and the

brakes will be applied to all wheels.

ESP

trailer stabilization may be impaired or may

not function if:

The trailer is not connected correctly or is not

detected properly by the vehicle.

terized by the following:

Monitoring and regulating the brake pressure

on the rear wheels.

Improved driving stability when braking, espe-

cially on bends.

Function of STEER CONTROL

STEER CONTROL assists you by transmitting a

noticeable steering force to the steering wheel in

the direction required for vehicle stabilization.

This steering recommendation is given in the fol-

lowing situations:

both right wheels or both le wheels are on a

wet or slippery road surface when you brake

the vehicle starts to skid

System limits

function in the following situations:

ESP

is deactivated.

ESP

is malfunctioning.

The steering is malfunctioning.

If ESP

is malfunctioning, you will be assisted fur-

ther by the electric power steering.

164

Driving and parking

HOLD function

▌HOLD function

The HOLD function holds the vehicle at a stand-

still without requiring you to depress the brake

pedal, e.g. while waiting in trac.

The HOLD function is only an aid. The responsibil-

ity for the vehicle safely standing still remains with

the driver.

System limits

The HOLD function is only intended to provide

assistance when driving and is not a sucient

means of safeguarding the vehicle against rolling

away when stationary.

The incline must not be greater than 30%.

▌Activating/deactivating the HOLD function

WARNING Risk of an accident due to the

HOLD function being active when you

leave the vehicle

If the vehicle is only braked with the HOLD

function it could, in the following situations,

roll away:

If there is a malfunction in the system or in

the power supply.

If the HOLD function is deactivated by

depressing the accelerator pedal or brake

pedal, e.g. by a vehicle occupant.

Always secure the vehicle against rolling

away before you leave it.

Requirements

The vehicle is stationary.

The driver's door is closed or the seat belt on

the driver's side is fastened.

The vehicle has been started or has been

automatically switched o by the ECO start/

stop function.

transmission position j and/or by the electric

parking brake:

The seat belt is unfastened and the driver's

door is opened.

The vehicle is switched o.

There is a system malfunction.

The power supply is insucient.

Function of Hill Start Assist

Hill Start Assist holds the vehicle for a short time

when you pull away on a hill under the following

conditions:

The transmission is in position h or k.

The electric parking brake is released.

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 away.

WARNING Risk of accident and injury due

to the vehicle rolling away

Aer a short time, Hill Start Assist no longer

holds the vehicle.

Swily move your foot from the brake

pedal to the accelerator pedal. Do not

leave the vehicle when it is being held by

Hill Start Assist.

ATTENTION ASSIST

▌Function of ATTENTION ASSIST

ATTENTION ASSIST assists you on long, monoto-

nous journeys, e.g. on highways and trunk roads.

If ATTENTION ASSIST detects indicators of fatigue

or increasing lapses in concentration on the part

of the driver, it suggests taking a break.

ATTENTION ASSIST is only an aid. It cannot

always detect fatigue or lapses in concentration in

time. The system is not a substitute for a well-res-

ted and attentive driver. On long journeys, take

regular breaks in good time that allow for ade-

quate recuperation.

You can choose between two settings:

Standard: normal system sensitivity.

Sensitive: higher system sensitivity. The driver

is warned earlier and the attention level detec-

ted by ATTENTION ASSIST is adapted accord-

ingly.

If drowsiness or increasing lapses in concentra-

tion are detected, the

ATTENTION ASSIST: Take

a Break!

warning appears in the Instrument Dis-

play. You can acknowledge the message and take

a break where necessary. If you do not take a

break and ATTENTION ASSIST continues to detect

increasing lapses in concentration, you will be

warned again aer a minimum of 15 minutes.

166

Driving and parking

You can have the following status information for

ATTENTION ASSIST displayed in the assistance

menu of the on-board computer:

The length of the journey since the last break.

The attention level determined by ATTENTION

ASSIST.

If ATTENTION ASSIST is unable to calculate the

attention level and cannot issue a warning, the

System Suspended message appears.

If a warning is given in the Instrument Display, the

multimedia system oers to search for a rest

area. You can select a rest area and start naviga-

tion to this rest area. This function can be activa-

ted and deactivated in the multimedia system.

If ATTENTION ASSIST is deactivated, the Û

symbol appears in the assistance graphic in the

Instrument Display. Aer the vehicle is started,

ATTENTION ASSIST is automatically activated. The

last selected sensitivity level remains stored.

System limits

ATTENTION ASSIST is active in the 37 mph

(60 km/h) to 124 mph (200 km/h) speed range.

Particularly in the following situations, ATTENTION

ASSIST only functions in a restricted manner and

warnings may be delayed or not occur:

If you have been driving for less than approx-

imately 30 minutes.

If the road condition is poor (uneven road sur-

face or potholes).

If there is a strong side wind.

If you adopt a sporty driving style (high corner-

ing speeds or high rates of acceleration).

If the time has been set incorrectly.

If you change lanes and vary your speed fre-

quently in active driving situations.

The ATTENTION ASSIST drowsiness or alertness

assessment is reset and restarted when continu-

ing the journey in the following situations:

If you switch o the vehicle.

If you unfasten your seat belt and open the

driver's door (e.g. to change drivers or take a

break).

▌Setting ATTENTION ASSIST

If ATTENTION ASSIST detects fatigue or

increasing lack of attention, it suggests a rest

area in the vicinity.

Select a suggested rest area: you are guided

to the selected rest area.

Speed control cruise control

▌Function of cruise control

Cruise control regulates the speed to the value

selected by the driver.

If you accelerate to overtake, forexample, the

stored speed is not deleted. If you remove your

Driving and parking

167

foot from the accelerator pedal aer overtaking,

cruise control will resume speed regulation back

to the stored speed.

You can store any speed above 15 mph

(20 km/h) up to the maximum design speed.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognize

dangers (/ page 159).

Mercedes‑AMG vehicles: cruise control is availa-

ble up to a maximum speed of 155 mph

(250 km/h).

Displays in the Instrument Display

h (gray): cruise control is selected but not

yet activated.

h (green): cruise control is active.

A stored speed appears along with the h dis-

play.

The segments between the stored speed and

the end of the segment display light up in the

speedometer.

System limits

Cruise control may be unable to maintain the

stored speed on uphill gradients. The stored

speed is resumed when the gradient evens out.

Change 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 eect of the engine.

This relieves the load on the brake system and

prevents the brakes from overheating and wearing

too quickly.

Do not use cruise control in the following situa-

tions:

in trac situations which require frequent

changes of speed, e.g. in heavy trac, on

winding roads

on slippery roads. Accelerating can cause the

drive wheels to lose traction and the vehicle

could then skid.

when visibility is poor

▌Operating cruise control

WARNING Risk of accident due to stored

speed

If you call up the stored speed and this is

lower than your current speed, the vehicle

decelerates.

Take into account the trac situation

before calling up the stored speed.

Active Distance Assist DISTRONIC

▌Function of Active Distance Assist DISTRONIC

DISTRONIC Active Distance Assist maintains the

set speed when driving freely. If vehicles are

detected ahead, the set distance is maintained, if

necessary until the vehicle comes to a standstill.

The vehicle accelerates or brakes depending on

the distance to the vehicle in front and the set

speed. The speed (in the range between 15 mph

(20 km/h) and 120 mph (200 km/h)) and the dis-

tance to the vehicle in front are set and saved on

the steering wheel.

Adjusts the driving style depending on the

selected drive program (fuel-saving, comforta-

ble or dynamic) (/ page 137)

Initiates acceleration to the stored speed if the

turn signal indicator is switched on to change

to the overtaking lane

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognize

dangers (/ page 159).

System limits

The system may be impaired or may not function

in the following situations,for example:

In snow, rain, fog, heavy spray, if there is glare,

in direct sunlight or in greatly varying ambient

light.

If there is swirling dust, e.g. when driving o-

road or on sandy surfaces.

The windshield in the area of the camera is

dirty, fogged up, damaged or covered.

If the radar sensors are dirty or covered.

In parking garages or on roads with steep

uphill or downhill gradients.

If there are narrow vehicles in front, such as

bicycles or motorcycles.

In addition, on slippery roads, braking or acceler-

ating can cause one or several wheels to lose

traction and the vehicle could then skid.

Do not use Active Distance Assist DISTRONIC in

these situations.

WARNING Risk of accident from accelera-

tion or braking by Active Distance Assist

DISTRONIC

Active Distance Assist DISTRONIC may accel-

erate or brake in the following cases, for

example:

If the vehicle pulls away using Active Dis-

tance Assist DISTRONIC.

If the stored speed is called up and is con-

siderably faster or slower than the cur-

rently driven speed.

If Active Distance Assist DISTRONIC no

longer detects a vehicle in front or does

not react to relevant objects.

Always carefully observe the trac con-

ditions and be ready to brake at all

times.

Active Brake Assist

▌Function of Active Brake Assist

Active Brake Assist consists of:

Distance warning function

Autonomous braking function

Situation-dependent brake force boosting

Active Brake Assist can help you to minimize the

risk of a collision with vehicles or pedestrians or

to reduce the eects of such a collision.

172

Driving and parking

If Active Brake Assist has detected a risk of colli-

sion, a warning tone sounds and the L warn-

ing lamp lights up in the Instrument Display.

If you do not react to the warning, autonomous

braking can be initiated in critical situations.

In especially critical situations, Active Brake Assist

can initiate autonomous braking directly. In this

case, the warning lamp and warning tone occur

simultaneously with the braking application.

If you apply the brake yourself in a situation

detected as critical by Active Brake Assist, or

apply the brake during autonomous braking, situa-

tion-dependent brake force boosting occurs. The

brake pressure increases up to maximum full-stop

braking if necessary.

If the autonomous braking function or the situa-

tion-dependent brake force boosting is triggered,

additional preventive measures for occupant pro-

tection (PRE-SAFE

) may also be initiated, if the

vehicle is equipped with these.

WARNING Risk of an accident caused by

limited detection performance of Active

Brake Assist

Active Brake Assist cannot always clearly iden-

tify objects and complex trac situations.

In such cases, Active Brake Assist might:

Give a warning or brake without reason

Not give a warning or not brake

Active Brake Assist is only an aid. The driver is

responsible for maintaining a suciently safe

distance to the vehicle in front, vehicle speed

and for braking in good time.

Always pay careful attention to the trac

situation; do not rely on Active Brake

Assist alone.

Be prepared to brake or swerve if neces-

sary.

Observe the system limitations of Active Brake

Assist.

The individual subfunctions are available in the fol-

lowing speed ranges:

Distance warning function

The distance warning function issues a warning at

speeds:

From approximately 4 mph (7 km/h), if your

vehicle is critically close to a vehicle or pedes-

trian. An intermittent warning tone sounds and

the L distance warning lamp lights up in

the Instrument Display.

Brake immediately or take evasive action, if it is

safe to do so and the trac situation allows this.

The distance warning function can aid you in the

following situations with an intermittent warning

tone and a warning lamp:

Vehicles traveling in

Trac Sign Assist

▌Function of Trac Sign Assist

Trac Sign Assist detects trac signs with the

multifunction camera (/ page 159). It assists

you by displaying detected speed limits and over-

taking restrictions in the Instrument Display.

Observe the notes on driving systems and your

responsibility; you may otherwise fail to recognize

dangers (/ page 159).

Since Trac Sign Assist also uses the data stored

in the navigation system, it can update the display

in the following situations without detecting trac

signs.

The camera also detects trac signs with a

restriction indicated by an additional sign (e.g.

when wet). These are only displayed if a restric-

tion applies or if the system cannot clearly deter-

mine whether the restriction applies.

Warning when the maximum permissible speed is

exceeded

The system can warn you if you unintentionally

exceed the maximum permissible speed. Depend-

ing on the country, you can set in the multimedia

Driving and parking

175

system by how much the maximum permitted

speed may be exceeded before a warning is given.

You can specify whether the warning is to be just

a visual warning or an acoustic one as well.

System limits

The system may be impaired or may not function

particularly in the following situations:

If there is poor visibility, e.g. due to insucient

illumination of the road, highly variable shade

conditions, rain, snow, fog or heavy spray.

If there is glare, e.g. from oncoming trac,

direct sunlight or reections.

If there is dirt on the windshield in the vicinity

of the multifunction camera or if the camera is

fogged up, damaged or obscured.

If the trac signs are hard to detect, e.g. due

to dirt, snow or insucient lighting, or

because they are obscured.

If the information on the navigation system's

digital map is incorrect or out of date.

If signs are ambiguous, e.g. road signs in road-

works or in adjacent lanes.

If you turn sharply when passing trac signs

outside the camera's eld of vision.

Blind Spot Assist

▌Function of Blind Spot Assist

Blind Spot Assist uses two lateral, rear-facing

radar sensors to monitor the area up to 130 

(40 m) behind and 10  (3 m) directly next to your

vehicle.

If a vehicle is detected at speeds above approx-

imately 8 mph (12 km/h) and this vehicle subse-

quently enters the monitoring range directly next

to your vehicle, the warning lamp in the outside

mirror lights up red.

If a vehicle is detected close to the side of your

vehicle, the red warning lamp in the outside mirror

ashes. If you switch on the turn signal indicator

in the corresponding direction, a warning tone

sounds once. If the turn signal indicator remains

switched on, all other detected vehicles are indi-

cated only by the ashing of the red warning

lamp.

If you overtake a vehicle quickly, no warning is

given.

176

Driving and parking

WARNING Risk of accident despite Blind

Spot Assist

Blind Spot Assist does not react to vehicles

approaching and overtaking you at a greatly

dierent speed.

Blind Spot Assist cannot warn drivers in this

situation.

Always pay careful attention to the trac

situation 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 su-

cient distance to the side for other road users and

obstacles.

System limits

The system may be limited in the following situa-

tions:

If there is dirt on the sensors or the sensors

are obscured

In poor visibility, e.g. due to fog, heavy rain or

snow

If there are narrow vehicles, e.g. bicycles or

motorbikes

If the road has very wide or narrow lanes

If vehicles are not driving in the middle of their

lane

Warnings may be issued in error when driving

close to crash barriers or similar continuous lane

borders. Always make sure that there is sucient

distance to the side for other trac or obstacles.

Warnings may be interrupted when driving along-

side long vehicles, for example trucks, for a pro-

longed time.

Blind Spot Assist is not operational when reverse

gear is engaged.

Blind Spot Assist is not operational when a trailer

is coupled to the vehicle and the electrical con-

nection has been correctly established.

Active Lane Keeping Assist

▌Function of Active Lane Keeping Assist

Active Lane Keeping Assist monitors the area in

front of your vehicle by means of a multifunction

camera (/ page 159). It serves to protect you

against unintentionally leaving your lane. You will

be warned by vibration pulses in the steering

wheel and guided back into your lane by a course-

correcting brake application.

Active Lane Keeping Assist is available in the

speed range between 37 mph (60 km/h) and

124 mph (200 km/h).

Active Lane Keeping Assist can neither reduce the

risk of an accident if you fail to adapt your driving

style nor override the laws of physics. It cannot

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

tions. Active Lane Keeping Assist is only an aid.

You are responsible for maintaining a safe dis-

tance, for vehicle speed, for braking in good time

and for staying in lane.

Driving and parking

177

If a lane-correcting brake application occurs, dis-

play 1 will appear on the instrument display.

The system does not apply the brake on the corre-

sponding side if you activate the turn signal indi-

cator.

Vehicles with Driving Assistance Package: if the

system detects an obstacle, such as another vehi-

cle in the adjacent lane, it will apply the brake

regardless of the turn signal indicator.

You will be warned by vibrations in the steering

wheel in the following circumstances:

Active Lane Keeping Assist detects a lane

marking.

A front wheel drives over this lane marking.

Conditions for a course-correcting brake applica-

tion

Lane markings were detected on both sides of the

lane. The front wheel drives over a continuous

lane marking.

A brake application may be interrupted at any

time by steering slightly in the opposite direc-

tion.

System limits

No lane-correcting brake application will occur in

the following situations:

You clearly and actively steer, brake or accel-

erate.

If a driving safety system intervenes, such as

ESP

, Active Brake Assist or Active Blind Spot

Assist.

You have adopted a sporty driving style with

high cornering speeds or high rates of acceler-

ation.

When ESP

is deactivated.

When you are driving with a trailer and the

electrical connection to the trailer has been

correctly established.

If a loss of tire pressure or a defective tire is

detected and displayed.

If you deactivate the Active Lane Keeping Assist

warning and the lane markings were not clearly

detected, it is possible that no lane-correcting

brake application will take place (/ page 180).

The system may be impaired or may not function

particularly in the following situations:

If there is poor visibility, e.g. due to insucient

illumination of the road, highly variable shade

conditions, rain, snow, fog or heavy spray.

If there is glare, e.g. from oncoming trac, the

sun or reections.

If there is dirt on the windshield in the vicinity

of the multifunction camera or if the camera is

fogged up, damaged or obscured.

If there are no lane markings or several

unclear lane markings are present for one

lane, e.g. around roadworks.

If the lane markings are worn, dark or cov-

ered.

178

Driving and parking

If the distance to the vehicle in front is too

short and thus the lane markings cannot be

detected.

If the lane markings change quickly, e.g. lanes

branch o, cross one another or merge.

If the road is very narrow and winding.

▌Activating/deactivating Active Lane Keeping

Assist

WARNING Risk of accident despite Active

Lane Keeping Assist warning

Parking Assist PARKTRONIC

▌Function of Parking Assist PARKTRONIC

Parking Assist PARKTRONIC is an electronic park-

ing assistance system with ultrasound. It monitors

the area around your vehicle using multiple sen-

sors on the front bumper and on the rear bumper.

Parking Assist PARKTRONIC shows you the dis-

tance between your vehicle and a detected obsta-

cle visually and audibly.

Parking Assist PARKTRONIC is only an aid. It is

not a substitute for your attention to the surround-

ings. The responsibility for safe maneuvering and

parking remains with you. Make sure that there

are no persons, animals or objects in the maneu-

vering area while maneuvering and parking in/

exiting parking spaces.

In the standard setting, an intermittent warning

tone sounds from a distance of approximately

1.0  (0.3 m) to an obstacle in front and approx-

imately 3.3  (1.0 m) to an obstacle behind. A

continuous warning tone sounds from a distance

of approximately 0.7  (0.2 m). Using the

If a warning tone also sounds for approximately

two seconds every time the vehicle is started, it

may be due to one of the following causes:

The sensors are dirty: clean the sensors and

observe the notes on care of vehicle parts

(/ page 326).

Parking Assist PARKTRONIC has been deacti-

vated due to a malfunction: restart the vehi-

cle. If the problem persists, consult a qualied

specialist workshop.

▌Function of the passive side impact protection

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 to be detected, the

sensors in the front and rear bumper must 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. The lateral segments light up orange or

red, depending on the distance to the obstacle.

Segment color depending on distance

Orange: approximately 1 - 2  (30 - 60 cm)

Red: < 1  (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. Only when the

vehicle has traveled a vehicle's length can all of

the lateral, front and rear segments be displayed.

Active Parking Assist

▌Function of Active Parking Assist

In the LOW RANGE o-road gear, Active Park-

ing Assist is not available if the dierential

locks are engaged and in the ë drive pro-

gram.

Active Parking Assist is an electronic parking

assistance system which uses ultrasound and is

automatically activated during forward travel. The

system is operational at speeds of up to approx-

imately 22 mph (35 km/h). When all the condi-

tions are fullled, the c symbol appears in the

Instrument Display and the system automatically

searches for and measures parking spaces on

both sides of the vehicle parallel and perpendicu-

lar to the direction of travel. If Active Parking

Assist is activated, suitable parking spaces are

displayed in the media display. The ë symbol

appears in the media display. The arrows show on

which side of the road free parking spaces are

located.

The parking space and, if necessary, the parking

direction can be selected as desired. Active Park-

ing Assist calculates a suitable vehicle path and

assists you in parking and exiting the parking

space.

Active Parking Assist provides assistance when

changing gear, accelerating, braking and steering

the vehicle.

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.

Active Parking Assist is canceled if, among other

things, one of the following actions is carried out:

You deactivate Parking Assist PARKTRONIC.

You deactivate Active Parking Assist.

You begin steering.

You apply the parking brake.

System limits

Objects located above or below the detection

range of Active Parking Assist are not detected

when the parking space is being measured. These

are also not taken into account when the parking

maneuver is calculated, e.g. overhanging loads,

overhangs or loading ramps of trucks, or the

boundaries of parking spaces. In some circum-

stances, Active Parking Assist may therefore

guide you into the parking space prematurely.

WARNING 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.

Vehicles with automatic transmission: The

vehicle may not stop in front of these

objects.

This could cause a collision.

In these situations, do not use Active

Parking Assist.

Snowfall or heavy rain may lead to a parking

space being measured inaccurately. Parking

spaces that are partially occupied by trailer draw-

bars might not be identied as such or be meas-

ured 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 suchas ice,

packed snow or in heavy rain.

When transporting a load that protrudes

beyond the vehicle.

ing spaces at right angles to the direction of travel

in the following situations:

If two parking spaces are located immediately

next to each other.

If the parking space is immediately next to a

low obstacle suchas a curb.

Active Parking Assist will not assist you with park-

ing spaces parallel or at right angles to the direc-

tion of travel in the following situations:
