Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems.
Antilock Brake System
ABS
ABS prevents locking of the wheels duringbraking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop. This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the power wheels
when driving off and accelerating.
DSC also recognizes unstable vehicle conditions
such as fishtailing or nose-diving. Within the
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 situationAn appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
curves.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.Seite 109Driving stability control systemsCONTROLS109

Hot exhaust systemHot exhaust system
High temperatures are generated in the
exhaust system.
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 while driving, while in idle posi‐
tion mode, or when parked. Such contact could
lead to a fire, resulting in an increased risk of
serious personal injury as well as property dam‐
age.
Do not touch hot exhaust pipes; otherwise,
there is a 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, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and mo‐
bile communication devices can interfere with
each other. In addition, there is no assurance
that the radiation generated during transmis‐
sion will be conducted away 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. ◀Driving through water
Drive through calm water only if it is not deeper
than 9.8 inches/25 cm and at this height, no
faster than walking speed, up to 3 mph/5 km/h.
Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the transmis‐
sion may be damaged. ◀
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Applying the brakes fully is the most effective
way of braking in situations needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
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 pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
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 attached to
floor.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning,
e.g. ◀
Driving in wet conditions When roads are wet or in heavy rain, press
brake pedal ever so gently every few miles.Seite 153Things to remember when drivingDRIVING TIPS153

Tire damage
General information Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Hints
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-
profile tires.
Indications of tire damage or other vehicle de‐
fects:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
rims and tires checked right away; otherwise,
there is the increased risk of an accident.
Drive carefully to the nearest service center.
Have the vehicle towed or transported there.
Otherwise, tire damage can become life threat‐
ening for vehicle occupants and also other traf‐
fic. ◀
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.
If work is not carried out properly, there is a
danger of subsequent damage and related
safety hazards. ◀
Wheel and tire combination Information on the correct wheel-tire combina‐
tion and rim versions for your vehicle can be
obtained from your 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
You should only use wheels and tires that
have been approved by the vehicle manufac‐
turer for your vehicle type; otherwise, e.g., de‐
spite having the same official size ratings, varia‐
tions can lead to chassis contact and with it, the
risk of severe accidents
The manufacturer of your vehicle cannot evalu‐
ate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle. ◀Seite 179Wheels and tiresMOBILITY179
