reverse.4.Set the parking brake.
Engine start as usual via Start/Stop button.
Automatic deactivation
In certain situations, Auto Start/Stop function is
deactivated automatically for safety reasons as
if the driver were absent.
MalfunctionThe Auto Start/Stop function no longer switches
off the engine automatically. A Check Control
message is displayed. It is possible to continue
driving. Have the system checked.

Releasing
Raise lever slightly, press the button and guide
the lever down.
Hints Use while driving
On rare occasions if it is necessary to use
the parking brake while driving, do not use ex‐
cessive force when applying it. When using it,
keep the button on the lever depressed.
Otherwise, using excessive force when applying
the parking brake may cause the rear wheels to
lock, resulting in fishtailing. ◀
To prevent corrosion and one-sided brake ac‐
tion, lightly apply the parking brake periodically
while coasting, if traffic conditions permit.
The brake lights will not light up if the parking
brake is set.

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.
Antilock Brake 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.
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 94CONTROLSDriving stability control systems94

▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.
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 Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent 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 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. ◀
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 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,

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. If
necessary, have the vehicle towed or trans‐
ported there. Otherwise, tire damage can be‐
come life threatening for vehicle occupants and
also other traffic. ◀
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. ◀
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.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
