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.
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.
CBC Cornering Brake
Control
When braking during curves or when braking
during a lane change, driving stability and
steering response are improved further.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistantWhen 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The laws of physics cannot be repealed, even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.Seite 96ControlsDriving stability control systems96

sounds.
The system requests that the you
intervene by braking and carrying
out evasive maneuvers, if necessary. The sys‐
tem cannot independently restore the distance
to the vehicle ahead.
This display does not relieve the driver of the
responsibility to adapt his or her desired driv‐
ing speed and style to the traffic conditions.
Display 2 flashes yellow.
The conditions necessary for op‐
eration of the system are no lon‐
ger met, e.g., due to ABS or DSC
intervention. The system applies the brakes
until you actively assume control.
Radar sensor
Position
The radar sensor is integrated in the bumper.
Dirty or covered sensor
A dirty or covered sensor may hinder the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.
Malfunction
The system cannot be activated if the radar
sensor is not aligned correctly. Misalignment
may be caused by damage incurred during
parking, for example.

Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system during driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, and with it the risk of seri‐
ous personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is the danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones without a direct con‐
nection to an external aerial in the vehicle's
passenger compartment. Otherwise, the vehi‐
cle electronics and mobile communication de‐ vices can interfere with each other. In addition,
there is no assurance that the radiation gener‐
ated during transmission will be discharged
from the vehicle interior.◀
Hydroplaning On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
The risk of hydroplaning increases as the tire
tread depth decreases. Minimum tread depth,
refer to page 266.
Driving through water
Maximum water height: 17 inches/45 cm.Adhere to water depth and speed limita‐
tions
Do not exceed this water depth and walking
speed; otherwise, the vehicle's engine, the
electrical systems and the transmission may
be damaged.◀
Braking safely
Your vehicle is equipped with ABS as a stand‐ ard feature.
Applying the brakes fully is the most effective
way of braking in situations when this is neces‐
sary.
The vehicle maintains steering responsive‐
ness. You can still avoid any obstacles with a
minimum of steering effort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
Do not let your foot rest on the brake
pedal
Do not drive with your foot resting on the brake
pedal. Even light but consistent pedal pressure
can lead to high temperatures, brake wear and
possibly even brake failure.◀
Objects in the area around the pedals No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again when they are returned after being
removed, such as for cleaning.◀Seite 147Things to remember when drivingDriving tips147

Indications of tire damage or other vehicle de‐
fects:▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can be caused by driving over curbs,
road damage and similar situations.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; other‐
wise, there is the increased risk of an accident.
Drive carefully to the next service center or tire
shop.
If necessary, have the vehicle towed.
Otherwise, tire damage can present a life-
threatening hazard to vehicle occupants and
other road users.◀
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center or tire specialist.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
Wheel and tire combination
Information on the right wheel and tire combi‐
nation and rim version for your vehicle can be
obtained from the service center.
Incorrect wheel and tire combinations impair
the function of a variety of systems such as
ABS or DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body con‐
tact and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot ensure the operating safety of the vehi‐
cle if they are mounted.◀
Wheels with electronics for TPM Tire
Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics; otherwise, the
Tire Pressure Monitor will not be able to detect
a flat tire, refer to page 90. Your service center
will be glad to advise you.Seite 267Wheels and tiresMobility267
