The sensor is a component of the ACC » page 214 and Front Assist
» page 219 systems.
The sensor function may be impaired in the events of one of the following. ▶ The sensor cover is soiled (e.g. with mud, snow etc.).
▶ The area in front of and around the sensor cover is obscured (e.g. by labels,
auxiliary headlights etc.).
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is covered or dirty, the corresponding message appears in the in-
strument cluster display for the ACC system » page 218, Malfunctions or Front
Assist system » page 221, Malfunctions .WARNING■
If you suspect that the sensor is damaged, deactivate the ACC system and
Front Assist system » page 216» page 220 . Have the sensor checked by a
specialist garage.■
A collision or damage in the front or lower area of the vehicle could affect
the sensor function - there is risk of accident! Have the sensor checked by
a specialist garage.
■
Do not cover the area in front of and around the sensor cover. This can
lead to impaired function of the sensor - risk of accidents!
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 32, Warning lights .
WARNINGThe general information relating to the use of assistance systems must be
observed » page 199, in section Introduction .
Stability Control (ESC)
Read and observe
on page 200 first.
ESC improves vehicle stability in critical driving situations (e.g. if the vehicle
starts to skid) by the braking the individual wheels to maintain the direction.
If there is a TCS intervention, the indicator light flashes in the instrument
cluster.
ESC Sport
Read and observe
on page 200 first.
ESC Sport allows for a sportier driving style. With ESC Sport activated, no ESC
intervention takes place when the vehicle slightly oversteers and understeers,
and ASR is so limited that the drive wheels can be spun.

The automatic distance control (hereinafter referred to as ACC) maintains the
set speed or the distance to the vehicle ahead without the accelerator or
brake pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 199.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
In the case of failure of a Xenon gas discharge bulb or an LED diode, visit a
specialist garage.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 252.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
