Slippery road surfaces

WARNING

Do not shift down for additional engine brak-

ing on a slippery road surface. This could

cause the drive wheels to lose their grip and

the vehicle could skid.

If the vehicle threatens to skid or cannot be

stopped when moving at low speed:

Vehicles with manual transmission:

shift to neutral.

Vehicles with automatic transmission:

shift the transmission to position N.

Try to bring the vehicle under control by

using corrective steering.

You should drive particularly carefully on slip-

pery road surfaces.Avoid sudden accelera-

tion, steering and braking manoeuvres.

For more information on driving with

snow chains, see (Y page 295).

Driving systems

Cruise control

General notes

Cruise control maintains a constant road

speed for you.Itbrakes automatically in order

to avoid exceeding the set speed. You must

select a lower gearingood time on long and

steep downhill gradients, especially if the

vehicle is laden or towing a trailer. For vehi-

cles with automatic transmission, you need

to have selected manual drive program

M(Y page 147). 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.

Use cruise control only if road and traffic con-

ditions make it appropriate to maintain a

steady speed for a prolonged period. You can

store any road speed above 30 km/h.

Important safety notes

WARNING

Do not change down for additional engine

braking on a slippery road surface. This could

cause the drive wheels to lose their grip and

the vehicle could skid.

WARNING

Cruise control cannot take account of road

and traffic conditions.

Always pay attention to traffic conditions

even when cruise control is activated.

Cruise control is only an aid designed to assist

driving. You are responsible for the vehicle's

speed and for braking in good time.

WARNING

Do not use cruise control

in traffic conditions that do not allow you to

drive at a constant speed (e.g. heavy traffic

or winding roads). You may otherwise

cause an accident.

on slippery roads. The drive wheels may

lose their grip when braking or accelerating

and the vehicle may skid.

General notes

SPEEDTRONIC brakes automatically so that

you do not exceed the set speed. You must

select a low gear in good time on long and

steep downhill gradients, especially if the

vehicle is laden or towing a trailer. For vehi-

cles with automatic transmission, you need

Driving systems

151

Driving and parking

to have selected manual drive program

M(Y page 147).By doing so, you will make

use of the braking effectofthe engine. This

relieves the load on the brake system and

prevents the brakes from overheating and

wearing too quickly. If you need additional

braking, depress the brake pedal repeatedly

rather than continuously.

You can set a variable or permanent limit

speed:

variable for speed limits, e.g. in built-up

areas

permanent for long-term speed restric-

tions, e.g. when driving with winter tyres

fitted (Y page 154)

The speed indicated in the speedometer

may differ slightly from the limit speed

stored.

Important safety notes

WARNING

Never depress the brake pedal continuously

while the vehicle is in motion, e.g. never cause

the brakes to rub by applying constant slight

pedal pressure. This causes the brake system

to overheat, increases the braking distance

and can lead to the brakes failing completely.

WARNING

Do not change down for additional engine

braking on a slippery road surface. This could

cause the drive wheels to lose their grip and

the vehicle could skid.

WARNING

SPEEDTRONIC is only an aid designed to

assist driving. You are responsible for the

vehicle's speed and for braking in good time.

DISTRONIC PLUS

Important safety notes

WARNING

Do not change down for additional engine

braking on a slippery road surface. This could

cause the drive wheels to lose their grip and

the vehicle could skid.

WARNING

DISTRONIC PLUS is only an aid designed to

assist driving. The driver remains fully respon-

sible for the vehicle's distance from other

vehicles, the vehicle's speed and for braking

in good time.

DISTRONIC PLUS does not react in particular

to:

pedestrians

stationary obstacles on the road, e.g. stop-

ped or parked vehicles

oncoming and crossing traffic

DISTRONIC PLUS may not detect narrowvehi-

cles driving in front, e.g. motorcycles, or vehi-

cles driving on a differentline. Therefore,

always pay attention to traffic conditions even

when DISTRONIC PLUS is activated. Other-

wise, you may fail to recognise dangers in

time, cause an accident and injure yourself

and others.

WARNING

DISTRONIC PLUS cannot takeaccount of road

and traffic conditions. If DISTRONIC doesnot

recognise or no longer recognises the vehicle

in front, do not activate DISTRONIC or, if it is

already active, deactivate it. This is especially

the case:

before corners

on filter lanes

when changing to a lane with faster moving

traffic

in complex driving situations or where lanes

are diverted, e.g. at roadworks on a motor-

way

DISTRONIC PLUS otherwise maintains the

current speed set by you or accelerates up to

the set speed.

DISTRONIC PLUS cannot take account of

weather conditions. Deactivate, or do not

activate, DISTRONIC PLUS:

if the roads are slippery, snow-covered or

icy. The wheels could lose their grip when

braking or accelerating. The vehicle could

start to skid.

if the sensors are dirty or there is poor vis-

ibility, e.g. due to snow, rain or fog. Dis-

tance control may be impaired.

Always pay attention to traffic conditions

even when DISTRONIC PLUS is activated.

Otherwise, you may fail to recognise dangers

in time, cause an accident and injure yourself

and others.

WARNING

DISTRONIC PLUS brakes your vehicle up to a

maximum of 4 m/s

depending on its speed.

This corresponds to approximately 40% of

your vehicle's maximum braking power. You

must also apply the brakes yourself if this

braking power is not sufficient.

If DISTRONIC PLUS detects a risk of collision

with avehicle in front, an intermittent warning

tone sounds. In addition, the · distance

warning lamp in the instrument cluster lights

up. Brake to avoid a collision.

154

Driving systems

Driving and parking

WARNING

The vehicle can be braked when DISTRONIC

PLUS is activated. For this reason, deactivate

DISTRONIC PLUS if the vehicle is to be set in

motion by other means (e.g. in a car wash or

by towing).

General notes

DISTRONIC PLUS regulates the speed and

automatically helps you maintainthe dis-

tance to the vehicle detected in front. DIS-

TRONIC PLUS brakes automatically so that

the set speed is not exceeded.

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. For

this, you need to have selected manual drive

program M(Y page 147). 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.

If DISTRONIC PLUS detects a slower-moving

vehicle in front, your vehicle is braked in order

to maintain the preset distance to the vehicle

in front.

If there is no vehicle in front, DISTRONIC

PLUS operates in the same way as cruise

control in the speed range between

30 km/h and 200 km/h. If avehicle is driving

in front of you, DISTRONIC operates in the

speed range between 0km/h and

200 km/h.

Do not use DISTRONIC PLUS on roads with

steep gradients.

To activate DISTRONIC PLUS, all of the fol-

lowing activation conditions mustbe fulfilled:

the engine must be running. It may take up

to two minutes of driving before DIS-

TRONIC PLUS is ready for use.

the electric parking brake must be

released.

ESP

the driver's door must be closed when you

shift from P to D or your seat belt must be

fastened.

the front-passenger door and the rear

doors must be closed.

the vehicle must not be skidding.

Switching on

To activate while driving: you can only acti-

vate DISTRONIC PLUS at speeds below

20 km/hifthe vehicle in front is detected and

shown in the multifunction display. If the vehi-

cle in front is no longer detected and dis-

played, DISTRONIC PLUS switches off and

you will hear a tone.

Briefly pull the cruise control level towards

you ?, or press it up : or down A.

DISTRONIC PLUS is selected.

Keep the cruise control lever pressed

up : or down A until the desired speed

is set.

Remove your foot from the accelerator

pedal.

Your vehicle adapts its speed to that of the

vehicle in front, but only up to the desired

stored speed.

If you do not fully release the accelerator

pedal, the

DISTRONIC PLUS inactive

message appears in the multifunction dis-

play.The set distance to a slower-moving

vehicle in front will then not be maintained.

You will be driving at the speed you deter-

mine by the position of the accelerator

pedal.

To activate when driving towards a sta-

tionary vehicle: if the vehicle in front is sta-

tionary, you can only activate DISTRONIC

PLUS if your vehicle is also stationary.

Briefly pull the cruise control level towards

you ?, or press it up : or down A.

DISTRONIC PLUS is selected.

DISTRONIC PLUS can only be activated at

under 20 km/h if a vehicle in front has been

detected. It is therefore helpful to have the

DISTRONIC PLUS distance display activa-

ted in the multifunction display

(Y page 198).

Keep the cruise control lever pressed

up : or down A until the desired speed

is set.

You can use the cruise control lever to set

the stored speed and the control on the

cruise control lever to set the specified

minimum distance (Y page 159).

Displaying DISTRONIC PLUS in the speedometer

When DISTRONIC PLUS is activated, one or

two segments ; in the set speed range light

up.

For design reasons, the speed displayed

in the speedometer may differ slightly from

the speed set for DISTRONIC PLUS.

If DISTRONIC PLUS detectsavehicle in front,

Driving

WARNING

If you depress the brake, DISTRONIC PLUS is

deactivated unless your vehicle is stationary.

DISTRONIC PLUS then no longer brakes your

vehicle. In such cases, control the distance

from vehicles travelling in front with the brake

alone. You could otherwise cause an accident

and thereby injure yourself and others. The

driver remains fully responsible for the vehi-

cle's distance from other vehicles, the speed

being driven and for braking in good time.

Pulling away

If the vehicle in front pulls away: remove

your foot from the brake pedal.

Briefly pull the cruise control lever

(Y page 155) towards you.

Accelerate briefly.

Your vehicle pulls away and adapts its

speed to that of the vehicle in front.

If there is no vehicle in front, DISTRONIC

PLUS operates in the same way as cruise

control.

If DISTRONIC PLUS detects that the vehicle

in front has slowed down, it brakes your vehi-

cle. In this way, the distance you have selec-

ted is maintained.

If DISTRONIC PLUS detects that the vehicle

in front is driving faster, it accelerates your

vehicle, but only up to the speed you have

stored.

Changing lane

WARNING

DISTRONIC PLUS is only an aid designed to

assist driving.

It is not a substitute for attentive driving. The

driver remains fully responsible for the vehi-

cle's distance from other vehicles, the vehi-

cle's speed and for braking in good time.

Always pay attention to traffic conditions and

your surroundings. Otherwise, you may fail to

recognise dangers in time, cause an accident

and injure yourself and others.

DISTRONIC PLUS supports you when you

DISTRONIC PLUS does not brake for obsta-

cles or stationary vehicles. If, for example, the

detected vehicle turns a corner and reveals

an obstacle or stationary vehicle, DISTRONIC

PLUS will not brake for these.

Driving and parking

Crossing vehicles

DISTRONIC PLUS may detect vehicles that

are crossing your lane by mistake. Activating

DISTRONIC PLUS at traffic lights with cross-

ing traffic, for example, could cause your vehi-

cle to pull away unintentionally.

HOLD function

General notes

The HOLD function can assistthe driver in the

following situations:

when pulling away, especially on steep

slopes

when manoeuvring on steep slopes

when waiting in traffic

The vehicle is kept stationary without the

driver having to depress the brake pedal.

The braking effect is cancelled and the HOLD

function is deactivated when you depress the

accelerator pedal to pull away.

Important safety notes

WARNING

The vehicle's brakes are applied when the

HOLD function is activated. For this reason,

deactivate the HOLD function if the vehicle is

to be set in motion by other means (e.g. in a

car wash or by towing).

WARNING

Never get out of the vehicle when the HOLD

function is activated.

The HOLD function must never be operated

or deactivated by a passenger or from outside

the vehicle.

The HOLD function does not replace the elec-

tric parking brake and must not be used for

parking.

The braking effect of the HOLD function is

cancelled and the vehicle could roll away if:

the HOLD function is deactivated by

depressing the accelerator pedal or the

brake pedal.

PARKTRONIC

Important safety notes

WARNING

PARKTRONIC is only an aid and may not

detect all obstacles. It is not a substitute for

attentive driving.

You are always responsible for safety and

must continue to pay attention to your imme-

diate surroundings when parking and

manoeuvring. You could otherwise endanger

yourself and others.

WARNING

Make sure that no persons or animals are in

the manoeuvring range. Otherwise, they

could be injured.

When parking, pay particular attention to

objects above or below the sensors, such

as flower pots or trailer drawbars. PARK-

TRONIC 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

objects which absorb ultrasonic sources.

Ultrasonic sources, such as an automatic

car wash, a lorry's compressed-air brakes

or a pneumatic drill, could cause PARK-

TRONIC to malfunction.

PARKTRONIC may not function correctly on

uneven terrain.

PARKTRONIC is an electronic parking aid with

ultrasonic sensors. It indicates visually and

audibly the distance between your vehicle

and an object.

PARKTRONIC is activated automatically if

you:

switch on the ignition

shift to position D, R or N on vehicles with

automatic transmission

release the electric parking brake

PARKTRONIC is deactivated at speeds above

18 km/h. It is reactivated at lower speeds.

PARKTRONIC monitors the area around your

vehicle using six sensors in the front bumper

and four sensors in the rear bumper.

Active Parking Assist

General notes

Active Parking Assist is an electronic parking

aid with ultrasound. Ultrasound is used to

measure the road on both sides of the vehicle.

Asuitable parking space is indicated by the

parking symbol. Active steering intervention

can assistyou during parking.

You may also use PARKTRONIC

(Y page 163). When PARKTRONIC is switched

off, Active Parking Assist is also unavailable.

Use Active Parking Assist for parking spaces:

that are parallel to the direction of travel

that are on straight roads, not bends

that are on the same level as the road, e.g.

not on the pavement

Important safety notes

WARNING

Active Parking Assist is merely an aid and may

sometimes recommend parking spaces that

are not suitable for parking. For example,

these might be spaces where parking is pro-

hibited, driveways, unsuitable surfaces, etc.

Active Parking Assist measures the parking

space as you drive past it. Any later changes

to the parking space are not taken into

account. For instance, this may be the case

when the vehicle parked in front of or behind

the space changes its position or when an

obstacle is moved into the parking space.

Active Parking Assist does not relieve you of

the responsibility of paying attention. If you

rely solely on Active Parking Assist, you could

cause an accident and injure yourself and oth-

ers.

166

Driving systems

Driving and parking

You are always responsible for safety and

must continue to pay attention to your imme-

diate surroundings when parking and

manoeuvring.

WARNING

Objects located above the height range of

Active Parking Assist will not be detected

when the parking space is measured.These

are not taken into account when the parking

procedure is calculated, e. g. overhanging

loads, tail sections or loading ramps of goods

vehicles. In some circumstances, Active Park-

ing Assist may therefore guide you into the

parking space too early. This may lead to a

collision. For this reason, you should avoid

using Active Parking Assist in such situations.

WARNING

The front of the vehicle will veer out in the

direction of the oncoming traffic during the

parking operation. In some cases the vehicle

will also take you onto sections of the oncom-

ing lane during the parking procedure.

You are responsible for safety at all times and

must pay attention to any road users

approaching or passing. Stop the vehicle if

necessary or cancel the Active Parking Assist

parking procedure.

WARNING

Make sure that no persons or animals are in

the manoeuvring range. Otherwise, they

could be injured.

If unavoidable, you should drive over

obstacles such as kerbs slowly and not at

a sharp angle. Otherwise, you may damage

the wheels or tyres.

Parking tips:

on narrow roads, drive as closely as possi-

ble past the parking space.

parking spaces that are littered, overgrown

or partially occupied by trailer drawbars

might be identified incorrectly or not at all.

snowfall or heavy rain may lead to a parking

space being measured inaccurately.

pay attention to the PARKTRONIC

(Y page 164) warning messages during the

parking procedure.

at any time, you can intervene in the steer-

ing procedure to correct it. Active Parking

Assist will then be cancelled.

when transporting a load which protrudes

from your vehicle, you should not use

Active Parking Assist.

never use Active Parking Assist when snow

chains are fitted.

make sure that the tyre pressures are

always correct.This has adirectinfluence

on the parking characteristics of the vehi-

cle.

the way your vehicle is positioned in the

parking space after parking is dependent

on various factors.These include the posi-

tion and shape of the vehicles parked in

front and behind it and the conditions of the

location. In some cases, Active Parking

Assist may guide 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 cancel

the parking procedure with Active Parking

Assist.

you can also engage forward gear prema-

turely. The vehicle redirects and does not

drive as far into the parking space. Should

a gear be changed too early to achieve a

sensible parking position, the parking pro-

cedure will be cancelled.

Detecting parking spaces

Active Parking Assist is switched on automat-

ically when driving forwards. The system is

operational at speeds of up to approximately

35 km/h. While in operation, the system inde-

pendently locates and measures parking

spaces on both sides of the vehicle. When

driving at speeds below 30 km/h, you will see

the parking symbol as a status indicator in the

instrumentcluster. Active Parking Assist only

ATTENTION ASSIST

Introduction

ATTENTION ASSIST helps you during long,

monotonous journeys such as on motorways

and trunk roads. It is active in the 80 km/h

to 180 km/h range.

If ATTENTION ASSIST detects typical indica-

tors of fatigue or increasing lapses in con-

centration on the part of the driver, it sug-

gests taking a break.

Important safety notes

WARNING

ATTENTION ASSIST is only an aid and may

detect your tiredness or lapses in concentra-

tion too late or not at all. It is not asubstitute

for a well rested and attentive driver.

Fatigue may cause you to recognise hazard-

ous situations too late, misjudge a situation

or react slower. For this reason, make sure

you feel rested before you begin driving and

during your journey. Always take breaks in

good time and regularly, especially during

long journeys. Otherwise, you may fail to rec-

ognise dangers in time, cause an accidentand

injure yourselfand others.

ATTENTIONASSIST assesses your level of

fatigue or lapses in concentration by taking

the following criteria into account:

your personal driving style, e.g. steering

characteristics

journey-related parameters, e.g. time of

day, length of journey

The functionality of ATTENTION ASSIST is

restricted, and warnings may be delayed or

not occur at all:

if the road condition is poor, e.g. if the sur-

face is uneven or if there are potholes

if there is a strong sidewind

if you have adopted a sporty driving style

with high cornering speeds or high rates of

acceleration

if you are predominantly driving slower

than 80 km/h or faster than 180 km/h

if you are currently using COMAND Online

or making a telephone call with COMAND

Online

if the time has been set incorrectly

in active driving situations, such as when

you change lanes or change your speed

On long journeys, take regularbreaks in good

time to allow yourself to rest properly.Ifyou

do not take a break, you will be warned again

after 15 minutes at the earliest. The precon-

dition for this is that ATTENTION ASSIST still

Speed Limit Assist

General notes

Speed Limit Assist shows you detected speed

limits in the multifunction display.Data from

the navigation system is also used for this

purpose. If a traffic sign indicating a speed

limit or the end of a speed limit is detected,

it is shown in the multifunction display. If

Speed Limit Assist does notdetectany traffic

signs, the speed limit from the digital road

map is takenand shown in the display.

Speed Limit Assist detects the traffic signs

with a camera attached behind the top of the

windscreen.

Important safety notes

WARNING

Speed Limit Assist is onlyanaid and may

detect speed limit signs incorrectly or not at

all.

The system may be impaired or may not func-

tion if:

there is poor visibility, e.g. due to snow,

rain, fog or spray.

there is glare, e.g. from the sun or from

oncoming traffic.

the windscreen is dirty, misted up or cov-

ered, for instance by a sticker, in the vicinity

of the camera.

the traffic signs are covered, for instance

by dirt, snow or trees.

the traffic signs are poorly illuminated.

there are ambiguous traffic signs, for

instance near roadworks or on multi-lane

roads.

Traffic signs always have priority over the

Speed Limit Assist display. Speed Limit Assist

cannot detect road and traffic conditions. It is

not a substitute for attentive driving.

Always pay attention to traffic conditions and

your surroundings. Otherwise, you may fail to

recognise dangers in time, cause an accident

and injure yourself and others.

Lane Tracking package

General notes

The Lane Tracking package consists of Blind

Spot Assist (Y page 177) and Lane Keeping

Assist (Y page 180).

Blind Spot Assist

General notes

Blind Spot Assist uses a radar sensor system

to monitor the areas on both sides of your

vehicle. It supports you from speeds of

30 km/h. A warning display in the exterior

mirrors draws your attention to vehicles

detected in the monitored area. If you then

switch on the corresponding turn signal to

change lane, you will also receive an optical

and audible collision warning. For this pur-

pose, Blind Spot Assist uses sensors in the

rear bumper.

Important safety notes

WARNING

Blind Spot Assist is only an aid designed to

assist driving. It may fail to detect some vehi-

cles and is no substitute for attentive driving.

Blind Spot Assist cannot detect road and traf-

fic conditions. It may fail to detect narrow

vehicles, such as motorcycles or bicycles, or

only detect them too late.

Monitoring may be affected by dirty sensors,

strong spray or poor visibility caused by snow,

Indicator and warning display

WARNING

Blind SpotAssist is not active at speeds below

30 km/h. The indicator lamps in the exterior

mirrors are yellow. Vehicles in the monitoring

range are then not indicated.

Always pay attention to traffic conditions and

your surroundings. Otherwise, you may fail to

recognise dangers in time, cause an accident

and injure yourselfand others.

Yellow indicator lamp/red warning lamp

If Blind SpotAssist is switched on, indicator

lamp : in the exterior mirrors lights up yel-

low up to a speed of 30 km/h. At speeds

above 30 km/h, the indicator lamp goes out

and Blind Spot Assist is operational.

If a vehicle is detected within the monitoring

range of Blind Spot Assist at speeds above

30 km/h, warning lamp : on the corre-

sponding side lights up in red. This warning is

always emitted when a vehicle enters the

blind spot monitoring range from behind or

from the side. When you overtake a vehicle,

the warning only occurs if the difference in

speed is less than 12 km/h.

The yellow indicator lamp goes out if reverse

gear is engaged. Blind Spot Assist is then

deactivated.

The brightness of the indicator/warning

lamps is adjusted automatically according to

the ambient light.

Collision warning

If a vehicle is detected in the monitoring range

of Blind Spot Assist and you switch on the

corresponding turn signal, a double warning

tone sounds. Red warning lamp : flashes. If

the turn signal remains on, detected vehicles

are indicated by the flashing of red warning

lamp :.There are no further warning tones.

Switching on Blind Spot Assist

On vehicles without an integrated naviga-

tion system, make sure that the Becker

MAP PILOT is connected; see the separate

operating instructions for Audio 20.

Make sure that the radar sensor system

(Y page 203) and Blind Spot Assist

(Y page 199) are activated in the on-board

computer.

Turn the key to position 2 in the ignition

lock.

Warning lamps : light up red in the exte-

rior mirrors for approximately 1.5 seconds

and then turn yellow.

Trailer towing

If you attach a trailer, make sure that you have

correctly established the electrical connec-

tion. This can be accomplished by checking

the trailer lighting. Blind Spot Assist is then

deactivated. The indicator lamp lights up yel-

low in the exterior mirrors and the

Blind

Spot Assist currently unavailable

range begins at 40 mph.

Important safety notes

WARNING

Lane Keeping Assist does not keep your vehi-

cle in its lane. It is only an aid and may detect

the lane markings on the road incorrectly or

not at all.

The system may be impaired or may not func-

tion if:

there is poor visibility, e.g. due to insuffi-

cient illumination of the road, or due to

snow, rain, fog or spray.

there is glare, e.g. from oncoming traffic,

the sun, or reflection from other vehicles.

the windscreen is dirty, misted up or cov-

ered, for instance by a sticker, in the vicinity

of the camera

several or no lane markings for a single lane

are present.

the lane markings are worn away, dark or

covered up, e.g. by dirt or snow.

the distance to the vehicle in front is too

small and the lane markings thus cannot be

detected.

the lane markings on the road are unclear,

e.g. near roadworks.

the lane markings change quickly, e.g.

lanes branch off, cross one another or

merge.

the road is narrow and winding.

Lane Keeping Assist cannot detect road and

traffic conditions. It is not a substitute for

attentive driving. You are responsible for the

vehicle's speed, braking in good time, and

steering correctly. Always adapt your driving

style to suit the prevailing road and weather

conditions. Always pay attention to traffic

conditions and your surroundings. Otherwise,

you may fail to recognise dangers in time,

cause an accidentand injure yourselfand oth-

ers.

A warning may be given if a front wheel

passes overalane marking. It will warn you

by means of intermittent vibration in the

steering wheel for up to 1.5seconds.

Towing atrailer

Notes on towing atrailer

Important safety notes

WARNING

When reversing the vehicle towards the

trailer, make sure there is nobody between

the trailer and the vehicle.

Couple and uncouple the trailer carefully.If

you do notcouple the trailer to the towing

vehicle correctly, the trailer could become

detached.

Make sure that the following values are not

exceeded:

the permissible trailer drawbar noseweight

the permissible trailer load

the permissible rear axle load of the towing

vehicle

the maximum permissible gross vehicle

weight of both the towing vehicle and the

trailer

You will find the applicable permissible val-

ues, which must not be exceeded, in the vehi-

cle documents.

You will find the values approved by the man-

ufacturer on the vehicle identification plates

and those for the towing vehicle in the "Tech-

nical data" section.

WARNING

If the Check trailer hitch locking

mechanism message appears in the multi-

function display while the vehicle is in motion,

pull over immediately and check whether the

ball coupling is correctly engaged.

WARNING

When towing a trailer, your vehicle's handling

characteristics will be different in comparison

to when driving without a trailer.

The vehicle/trailer combination:

is heavier

is restricted in its acceleration and gradi-

ent-climbing capability

has an increased braking distance

is affected more by strong crosswinds

demands more sensitive steering

has a larger turning circle

As a result, the handling characteristics may

be impaired and you may lose control of the

vehicle. This could lead to an accident with

serious or even fatal injuries.
