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 .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. The high beams are
switched on and off automatically.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.

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‐

Operational readiness of airbag
system
When the ignition is switched on,, refer
to page 58, the warning lamp comes on
briefly to indicate that the entire airbag
system and the belt tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up after
the ignition is switched on.▷Warning lamp 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.◀
FTM Flat Tire Monitor The conceptThe system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
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. Therefore, check the tire
inflation pressure regularly.
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.

driving resumes.
Indication of a flat tire The warning lamp lights up red. A
message appears on the Control Dis‐
play. In addition, a signal sounds.
There is a flat tire or a major loss in tire inflation
pressure.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
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
Run-flat tires Maximum speed
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.At the next opportunity, check the inflation
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.
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 ap‐
prox. 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

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 the system was not
reset
The yellow warning light lights up. ACheck 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 94.
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 pressuredecreases 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.

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.
Brake assistant 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.
Do not reduce the additional safety margin
with a risky driving style, as otherwise there is
a risk of an accident.◀
Deactivating DSC: DSC OFF When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.
