Automatic headlight control
Switch position
: the low beams are
switched on and off automatically, e.g., in tun‐
nels, in twilight or if there is precipitation. The
LED next to the symbol lights up.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
Personal responsibility
The automatic headlamp control cannot
serve as a substitute for your personal judg‐
ment in determining when the lamps should be
switched on in response to ambient lighting
conditions.
For example, the sensors are unable to detect
fog or hazy weather. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.◀
Daytime running lights

Adaptive Light Control
The concept Adaptive Light Control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.

High-beam Assistant The concept
When the lights are switched on, this system
automatically switches the high-beams on and
off. The procedure is controlled by a sensor on
the front of the interior rearview mirror. The as‐
sistant ensures that the high-beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high-beams on and off as usual.
Activating the High-beam Assistant1.Turn the light switch to position.2.With the low beams switched on, briefly
push the turn indicator lever in the direc‐
tion of the high-beam.
The indicator lamp in the instrument
cluster lights up.
When the lights are switched on, the
high-beams are switched on and off automati‐
cally.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.

The High-beam Assistant cannot serve
as a substitute for the driver's personal judg‐
ment of when to use the high beams. There‐
fore, manually switch off the high beams in sit‐
uations where this is required to avoid a safety
risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Sensor view field

Status of passenger airbags
The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica‐
tor lamp shows whether the passenger airbags
are activated or deactivated.
▷The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty.
The front and side airbags on the front
passenger side are not activated. Most
child seats are detected by the system. Es‐
pecially the child seats required by NHTSA
at the time that the vehicle was manufac‐
tured. After installing a child seat, make
sure that the indicator lamp for the front
passenger airbags lights up. This indicates
that the child seat has been detected and
the front passenger airbags are not acti‐
vated.▷The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front and front passenger air‐
bags on the front passenger side are acti‐
vated.Operational readiness of airbag
system
When the ignition, refer to page 58, is switched
on, the warning lamp comes on briefly to indi‐
cate that the entire airbag system and the belt
tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up when
the ignition is switched on.▷Warning light remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not func‐
tion as intended even if a sufficiently severe
accident occurs.◀
Flat Tire Monitor FTM The conceptThe system detects a pressure loss in a tire on
the basis of speed differences between the in‐
dividual wheels during a trip.
In the event of pressure loss, the rolling cir‐
cumference changes and, thus, the rotating
speed of the affected wheel. This change is
detected and is reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐

wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.

Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.

driving resumes.
Indication of a flat tire The warning lights come on in yellowand red. A message appears on the
Control Display. In addition, a signal
sounds.
There is a flat tire or a major loss in tire inflation
pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 234, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.Seite 95SafetyControls95

flation pressure.▷The system was not reset. The system
therefore issues warnings in case of devia‐
tions from the tire inflation pressures

vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 98, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
The use of tire sealant can damage the
TPM electronics. In this case, have theelectronics checked at the next opportu‐
nity and have them replaced if necessary.
Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.

A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Message when not reset The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 97.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐
ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. On the Control Display, the
tires are shown in gray and a message ap‐
pears. No flat tire can be detected.Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.
The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. The tires are displayed in gray
on the Control Display. No flat tire can be de‐
tected.
Display in the following situations:
▷Disturbance by systems or devices with
the same radio frequency. After leaving the
area of the disturbance, the system auto‐
matically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Activating/deactivating DSC DSC can be deactivated/activated via the DSC
OFF program of the Dynamic Driving Control,
refer to page 102.
For better control The DSC indicator lamp flashes: DSC
is controlling the drive forces and brake
forces.
The DSC indicator lamp lights up: DSC has
failed.Seite 101Driving stability control systemsControls101

Dynamic Traction Control
DTC
The concept The DTC system and the TRACTION program
are a variant of the DSC in which forward mo‐
mentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
