Driving and operating

Control indicator k illuminates.
A status message appears in the

Driver Information Centre when TC is

deactivated.
When TC is deactivated, ESC

remains active but with higher control

threshold.
TC is reactivated by pressing b

again. A status message pops up in

the Driver Information Centre when

TC is reactivated.
TC is also reactivated the next time

the ignition is switched on.

Fault

If there is a fault in the system the

control indicator b illuminates

continuously and a message appears

in the Driver Information Centre. The

system is not operational.

Have the cause of the fault remedied

by a workshop.

Electronic Stability Control

Electronic Stability Control (ESC)

improves driving stability when

necessary, regardless of the type of

road surface or tyre grip.
As soon as the vehicle starts to

swerve (understeer/oversteer),

engine output is reduced and the

wheels are braked individually.
ESC operates in combination with the

Traction Control system (TC). It

prevents the drive wheels from

spinning.
Torque distribution is a special

feature that allocates the torque to the

drive wheels before the ESC

intervenes. When cornering, the

wheels on the inner curve are braked

individually. Additionally, engine

torque will be delivered to the drive

wheel on the outer curve. This

reduces the tendency of

understeering and improves traction

when cornering fast.

ESC is operational after each engine

start as soon as the control indicator

b

 extinguishes.

When ESC operates b flashes.

9 Warning

Do not let this special safety

feature tempt you into taking risks

when driving.
Adapt speed to the road

conditions.

Adaptive cruise control

Adaptive cruise control is an

enhancement to conventional cruise

control with the additional feature of

maintaining a certain distance behind

the vehicle ahead.

188

Driving and operating

Adaptive cruise control automatically

decelerates the vehicle when

approaching a slower moving vehicle.

It then adjusts the vehicle speed to

follow the vehicle ahead at the

selected following distance. The

vehicle speed increases or decreases

to follow the vehicle in front, but will

not exceed the set speed. It may

apply limited braking with activated

brake lights.
The adaptive cruise control can store

set speed over 30 km/h for manual

transmission. On vehicles with

automatic transmissions the system

can brake until a full stop and drive off

from a stop.

Adaptive cruise control uses radar

and camera sensors to detect the

vehicles ahead. If no vehicle is

detected in the driving path, the

adaptive cruise control will behave

like a conventional cruise control.

For additional information including a

video, visit us online.
Adaptive cruise control is mainly

advised to be used on long straight

roads like highways or country roads

with steady traffic. Do not use the

system if it is not advisable to

maintain a constant speed.
Control indicator A 3 114, m 3 114,

C

 3 114.

9 Warning

The complete driver attention is

always required while driving with

adaptive cruise control. The driver

stays fully in control of the vehicle

because the brake pedal, the

accelerator pedal and the cancel

switch have priority over any

adaptive cruise control operation.

Switching on the system

Press v to switch on adaptive cruise

control. C appears in the Driver

Information Centre.

Activation of the funtionality

Adaptive cruise control can be

activated at speeds above 25 km/h on

vehicles with automatic transmission

or 30 km/h on vehicles with manual

transmission. The upper speed limit is

180 km/h.
Accelerate to the desired speed and

turn thumb wheel to SET/-, the

current speed is stored and

maintained.

Driving and operating

189

The adaptive cruise control symbol

C

, the following distance setting and

set speed are indicated in the Driver

Information Centre.
The accelerator pedal can be

released. Adaptive cruise control

remains activated during gear

shifting.

Overriding set speed

It is always possible to drive faster

than the selected set speed by

depressing the accelerator pedal.

When the accelerator pedal is

released, the vehicle returns to the

desired distance if a slower vehicle is

ahead. Otherwise it returns to the

stored speed.

Once the system is activated,

adaptive cruise control decelerates or

brakes if it detects a vehicle ahead,

which is slower or closer than the

desired following distance.

9 Warning

Accelerating by the driver

deactivates automatic braking by

the system. This is indicated as a

pop-up warning in the Driver

Information Centre or by the

adaptive cruise control symbol

turning blue.

Take over current speed

If the accelerator pedal is pressed,

the current vehicle speed is taken

over as stored speed. This is also

valid, if the current vehicle speed is

lower than the Set Speed.

Increase speed

With adaptive cruise control active,

hold RES/+ to increase speed

continuously. Push RES/+ repeatedly

to increase speed in small

increments.

Reduce speed

With adaptive cruise control active,

hold SET/- to decrease speed

continuously. Push SET/- repeatedly

to decrease speed in small

increments.

Resume stored speed

If the system is switched on but

inactive and a speed was stored

before, turn thumb wheel to RES/+ at

a speed above 5 km/h (with automatic

transmission) or above 30 km/h (with

manual transmission) to resume the

stored speed.

Full speed range adaptive cruise

control on vehicles with automatic

transmission

Full speed range adaptive cruise

control will maintain a following

distance behind a detected vehicle

and slow your vehicle to a stop behind

that vehicle.
When the vehicle ahead accelerates

after a brief stop, the adaptive cruise

control will drive off automatically

without driver action. If necessary,

190

Driving and operating

press RES/+ or the accelerator pedal

to resume adaptive cruise control.

Pressing the accelerator pedal allows

more control over the acceleration

after driving off. Note that automatic

braking is disabled during usage of

the accelerator pedal.
If the stopped vehicle ahead was

stopped for a longer time and then

begins to move forward, the green

illuminated vehicle ahead control

indicator A will flash and a warning

chime will sound as a reminder to

check traffic before proceeding.

9 Warning

When full speed range adaptive

cruise control is deactivated or

cancelled, the vehicle will no

longer be held at a stop and can

start moving. Always be prepared

to manually apply the brake pedal

to hold the vehicle stationary.
Do not leave the vehicle while it is

being held at a stop by the full

speed range adaptive cruise

control. Always move selector

lever to park position P and switch

off the ignition before leaving the

vehicle.

Setting the following distance

When adaptive cruise control detects

a slower moving vehicle in the driving

path, it will adjust the vehicle speed to

maintain the following distance

selected by the driver.
The following distance can be set to

near, medium or far.

Press l, the current setting is shown

in the Driver Information Centre.

Press l again to change the following

distance. The setting is also

displayed in the Driver Information

Centre.

The selected following distance is

indicated by filled distance bars in the

adaptive cruise control page.
Note that the following distance

setting is shared with the sensitivity

setting of forward collision alert

3

 195.

Example: If setting 3 (far) is selected,

then the driver is warned sooner

before a possible collision, also if

adaptive cruise control is inactive or

switched off.

Driving and operating

191

9 Warning

The Driver accepts full

responsibility to drive with the

appropriate following distance

based on traffic, weather, visibility

and regional regulation. Following

distance must be adjusted or the

system switched off when required

by the prevailing conditions.

Detecting the vehicle ahead

The green illuminated vehicle ahead

control indicator A is displayed when

the system detects a vehicle in the

driving path. The range of the sensors

is between 25 and 150 metres

depending on vehicle speed.
Forward collision alert 3 195.

If this symbol does not display, or

displays briefly, adaptive cruise

control will not respond to vehicles

ahead.

Deactivation of the functionality

Adaptive cruise control is deactivated

by the driver when:

● y is pressed.
● Brake pedal is applied.
● Clutch pedal is depressed for

more than four seconds.

● Selector lever of automatic

transmission is moved to N.

The system is also automatically

deactivated when:

● Vehicle speed accelerates above

190 km/h or slows down below

55 km/h Vehicles with automatic

transmission slows down to a

stop without deactivating within

five minutes.

● The Traction Control system is

deactivated or operating.

● The Electronic Stability Control is

deactivated or operating.

● There is no traffic and nothing

detected on the road sides for

approx. one minute. In this case

there are no radar echoes and

the sensor may report that it is

blocked.

● The active emergency braking

system is applying the brakes.

● Driving on steep inclines.
● The radar sensor is blocked by

an ice or water film.

● A fault is detected in the radar,

camera, engine or brake system.

● The brakes need to cool down.

Additionally, the system is

automatically deactivated on vehicles

with automatic transmission (full

speed range adaptive cruise control)

when:

● The incline uphill or downhill is

greater than 20%.

● The electric parking brake is

applied.

192

Driving and operating

● The vehicle is being held to a stop

by the system for more than

five minutes.

● The vehicle stops, the driver's

seat belt is unbuckled and the

driver's door is opened.

When adaptive cruise control is

deactivated, the control indicator C

changes from green to white and a

pop-up message is displayed in the

Driver Information Centre.
The stored speed is maintained.

On Midlevel display, the stored speed

is indicated in brackets in the Driver

Information Centre when the system

is deactivated but not switched off.
On Uplevel display, the adaptive

cruise control symbol C changes

from green to white when the system

is deactivated but not switched off.

9

Warning

When adaptive cruise control is

deactivated, the driver must take

over full brake and engine control

immediately.

Switching off the system

Press v to switch off adaptive cruise

control. The control indicatorC

extinguishes in the Driver Information

Centre. The stored speed is deleted.
Switching off the ignition also

switches off adaptive cruise control

and deletes the stored speed.

Driver's attention

● Use adaptive cruise control

carefully on bends or mountain

roads, as it can lose the vehicle

ahead and needs time to detect it

again.

● Do not use the system on

slippery roads as it can create

rapid changes in tyre traction

(wheel spinning), so that you

could lose control of the vehicle.

● Do not use adaptive cruise

control during rain, snow or

heavy dirt, as the radar sensor

can be covered by a water film,

dust, ice or snow. This reduces or

suppresses completely the

visibility. In case of sensor

blockage, clean the sensor

cover.

System limits

9 Warning

The system's automatic brake

force does not permit hard braking

and the braking level may not be

sufficient to avoid a collision.

● After a sudden lane change, the

system needs a certain time to

detect the next preceding

vehicle. So if a new vehicle is

detected, the system may

accelerate instead of braking.

Driving and operating

193

● Adaptive cruise control does

ignore the oncoming traffic.

● Adaptive cruise control does not

consider pedestrians and

animals for braking and driving

off.

● Adaptive cruise control considers

stopped vehicles only at low

speed.

● Do not use adaptive cruise

control when towing a trailer.

● Do not use adaptive cruise

control on roads with an incline of

more than 10%.

Bends

The adaptive cruise control calculates

a predicted path based on the

centrifugal force. This predicted path

considers the current bend

characteristic, but cannot consider a

future bend change. The system may

lose the current vehicle ahead or

consider a vehicle which is not in the

actual lane. This can happen when

entering or exiting a bend or if the

bend gets stronger or weaker. The

camrea applies a certain correction

based on the detectable lane

markings. The control indicator A will

extinguish, if a vehicle ahead is no

longer detected.
If the centrifugal force is too high in a

bend, the system slows down the

vehicle slightly. This braking level is

not designed to avoid spinning-off the

bend. The driver is responsible for

reducing the selected speed before

entering a bend and in general to

adapt the speed to the road type and

to existing speed limits.

Motorways

On motorways, adapt the set speed

to the situation and the weather.

Always consider that adaptive cruise

control has a limited visibility range, a

limited braking level and a certain

reaction time to verify if a vehicle is on

the driving path or not. Furthermore,

adaptive cruise control was designed

to brake as late as possible to allow

changing the lane before the

automatic braking. Adaptive cruise

control may not be able to brake the

vehicle in time to avoid a collision with

a much slower vehicle or after a lane

change. This is particularly true while

driving fast or if the visibility is

reduced due to weather conditions.
While entering or exiting a motorway,

adaptive cruise control may lose the

vehicle ahead and accelerate up to

the set speed. For this reason,

decrease the set speed before the

exit or before the entry.

194

Driving and operating

Vehicle path changes

If another vehicle enters your driving

path, adaptive cruise control will first

consider the vehicle when it is

completely in your path. Be ready to

take action and depress the brake

pedal, if you need to brake more

quickly.

Hill and trailer considerations

9 Warning

Do not use adaptive cruise control

on steep hill roads.

System performance on hills depends

on vehicle speed, vehicle load, traffic

conditions and the road gradient. It

may not detect a vehicle in your path

while driving on hills. Full speed range

adaptive control is deactivated

automatically, as the vehicle is

stopping uphill on an incline greater

than 10%. In this condition, be

prepared to take control of the

vehicle.
Note that applying the brake

deactivates the system.

Radar unit

The radar unit is mounted behind the

radiator grille behind or below the

brand emblem.

9 Warning

The radar unit was aligned

carefully during manufacture.

Therefore, in the event of a front-

end impact, do not use the system.

The front bumper may appear to

be intact, however the sensor

behind can be out of position and

react incorrectly. After an

accident, consult a workshop to

verify and adjust the radar unit

position.

Fault

If the adaptive cruise control does not

work due to temporary conditions

(e.g. blockage by ice, overheated

brakes or low speed manoeuvres) or

if there is a permanent system error,

then a message is displayed in the

Driver Information Centre.
Vehicle messages 3 123.

Forward collision alert

The forward collision alert may help to

avoid or reduce the harm caused by

front-end crashes.
If the vehicle is equipped with

conventional cruise control, the

forward collision alert uses the front

camera in the windscreen to detect a

vehicle directly ahead, in your path.
If the vehicle is equipped with

adaptive cruise control, the forward

collision alert uses the radar sensor to

detect a vehicle directly ahead, in

your path.

A vehicle ahead is indicated by the

control indicator A.
If a vehicle directly ahead is

approached too quickly, a warning

chime and alert in the Driver

Information Centre is provided.
Additionally the driver gets notified by

a flashing red LED stripe which is

projected on the windscreen in the

driver's field of view.
A precondition is that forward collision

alert with front camera system is not

deactivated by pressing V on the

steering wheel or, with radar sensor,

that it is not deactivated in the vehicle

personalisation menu 3 125.

Activation

Forward collision alert with front

camera detects vehicles to distances

of approximately 60 metres and

operates automatically at all speeds

above walking speed.
Forward collision alert with radar

sensor detects vehicles to distances

of approximately 150 metres and

operates automatically at all speeds

above walking speed.

Alerting the driver

The vehicle ahead control indicator

A

 illuminates green in the instrument

cluster when the system has detected

a vehicle in the driving path.
The control indicator A changes to

yellow when the distance to a

preceding moving vehicle gets too

small or when approaching another

vehicle too rapidly.

Caution

The colour lighting of this control

indicator does not correspond to

local traffic laws on following

196

Driving and operating

distance. The driver bears full

responsibility for maintaining safe

following distance according to

applicable traffic rules, weather

and road conditions etc. at all

times.

When the time to a potential collision

with a vehicle in front gets too small

and a collision is imminent, the

collision alert symbol pops-up in the

Driver Information Centre and the

driver gets notified by a warning

chime sound.
Depress the brake pedal and steer

the vehicle, if it is required by the

situation.

Selecting the alert sensitivity

Press V or E to set the alert

sensitivity to near, medium or far and

on some versions off.

The first button press shows the

current setting on the Driver

Information Centre. Additional button

presses will change this setting. The

chosen setting will remain until it is

changed. The alert timing will vary

based on vehicle speed. The faster

the vehicle speed, the farther away

the alert will occur. Consider traffic

and weather conditions when

selecting the alert timing.

Note that the alert timing sensitivity

setting is shared with the following

distance setting of the adaptive cruise

control. So changing the alert timing

sensitivity changes the adaptive

cruise control following distance

setting.

General information

9 Warning

Forward collision alert is just a

warning system and does not

apply the brakes. When

approaching a vehicle ahead too

rapidly, it may not provide you

enough time to avoid a collision.
The driver accepts full

responsibility for the appropriate

following distance based on traffic,

weather and visibility conditions.

The complete attention of the

driver is always required while

driving. The driver must always be

ready to take action and apply the

brakes.

System limitations

Forward collision alert is designed to

warn on vehicles only, but may react

also to other objects.
In the following cases, forward

collision alert may not detect a vehicle

ahead or sensor performance is

limited:

● on winding roads
● when weather limits visibility,

such as fog, rain, or snow

● when the sensor is blocked by

snow, ice, slush, mud, dirt,

windscreen damage or affected

by foreign items, e.g. stickers

Following distance

indication

The following distance indication

displays the distance to a preceding

moving vehicle. The front camera in

the windscreen is used to detect the

distance of a vehicle directly ahead in

the vehicle's path. It is active at

speeds above 40 km/h.
When a preceding vehicle is detected

ahead, the distance is indicated in

seconds, displayed on a page in the

Driver Information Centre.
On Midlevel display, choose Info

Menu ? via MENU on the turn

signal lever and turn the adjuster
