Head-up Display
Overview
The concept
This system projects important information into
the driver's field of vision, e. g., the speed.
The driver can quickly absorb information and
concentrate on the traffic situation.
Information CAUTION
The Head-up Display consists of sensitive
components that can easily be scraped or dam‐
aged. There is risk of property damage. Do not
place any objects on the Head-up Display, at‐
tach to system components or plug into the
system. Do not move the moving parts man‐
ually. ◀
WARNING
When extending and retracting the pro‐
jection screen of the Head-up Display, body
parts can be jammed. There is risk of injuries.
Make sure that the area of movement of the
projection screen is clear during opening and
closing. ◀
Follow the instructions for cleaning the Head-
up Display, refer to page 223.
Display visibility

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. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
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.
Information Adapt your driving style to the situation, for an
appropriate driving style is always the responsi‐
bility 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The laws of physics cannot be repealed, not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.
WARNING
When driving with roof load, e.g. with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is risk of
accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC when
driving with roof load. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.Seite 115Driving stability control systemsCONTROLS115

If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
WARNING
During driving operation, high tempera‐
tures can occur underneath the body, e.g.
caused by the exhaust gas system. If combusti‐
ble materials, such as leaves or grass, come in
contact with hot parts of the exhaust gas sys‐
tem, these materials can ignite. There is risk of
injuries or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in con‐
tact with hot vehicle parts in driving operation,
idle or during parking. Do not touch the hot ex‐
haust system. ◀
Mobile communication devices in the vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the send operations of mobile phones.
There is risk of injuries or risk of property dam‐
age. If possible, in the car's interior use only
mobile phones with direct connections to an
exterior antenna in order to exclude mutual
disturbance and deflect the radiation from the
car's 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.
Driving through water
CAUTION
When driving too quickly through too
deep water, water can enter into the engine
compartment, the electrical system or the
transmission. There is risk of property damage.
When driving through water, do not exceed the
maximum indicated water level and the maxi‐
mum speed for 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.
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 movement area around
pedals and floor area
WARNING
Objects in the driver's floor area can limit
the pedal distance or block a depressed pedal.
There is risk of an accident. Stow objects in the
vehicle such that they are secured and cannot
enter into the driver's floor area. Use floor mats
that are suitable for the vehicle and can be
safely attached to the floor. Do not use loose
floor mats and do not layer several floor mats.
Make sure that there is sufficient clearance for
the pedals. Ensure that the floor mats are se‐
curely fastened again after they were removed,
e.g. for cleaning. ◀Seite 159Things to remember when drivingDRIVING TIPS159

Tire damage
General information Inspect your tires often for damage, foreign ob‐
jects lodged in the tread, and tread wear.
Information 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 mal‐
functions:▷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.
WARNING
Damaged tires can lose tire inflation pres‐
sure, which can lead to loss of vehicle control.
There is risk of an accident. If tire damage is
suspected while driving, immediately reduce
speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to the
nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed. ◀
WARNING
Damaged tires can lose tire inflation pres‐
sure, which can lead to loss of vehicle control.
There is risk of an accident. Do not repair dam‐
aged tires, but have them replaced. ◀
Changing wheels and
tires
Mounting Have mounting and wheel balancing carried
out by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.
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.
WARNING
Wheels and tires which are not suitable
for your vehicle can damage parts of the vehi‐
cle, e. g. due to contact with the body due to
tolerances despite the same official size rating.
There is risk of an accident. ◀
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
