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
Dynamic Stability Control detect for example
the following unstable driving conditions:▷Fishtailing, which can lead to oversteering.▷Loss of traction of the front wheel, which
can lead to understeering.
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to the
individual wheels.
Information The system does not relieve the driver from his
responsibility to adjust his driving style accord‐
ing to the situation.
Therefore, adjust the driving style according to
the situation and do not reduce the additional
safety margin by driving in a risky manner.
WARNING
When driving with roof load, for example
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.

Deactivating DSC: DSC OFFWhen 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.
DSC is switched off.
Activating DSC Press button.
DSC OFF and the DSC OFF indicator
lamp go out.
Indicator/warning lights
When DSC is deactivated, DSC OFF is displayed
in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
Automatic activation When DSC is deactivated, automatic activation
occurs in the following situations:▷The vehicle has a flat tire.▷When activating cruise control in TRACTION
or DSC OFF mode.
DTC Dynamic Traction
Control
The concept
DTC is a version of the DSC where forward mo‐
mentum is optimized.
The system ensures maximum headway on
special road conditions, for example unplowed
snowy roads or loose road surfaces, but with
somewhat limited vehicle stability.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.
Deactivating/activating DTC Dynamic

TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press button again.
TRACTION and the DSC OFF indicator
lamp go out.
Performance Control
Performance Control enhances the agility of the
vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually.

Driving comfortVehicle 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.
Camera-based cruise con‐
trol
The concept
Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
A camera on the interior rear view mirror is
used to detect vehicles driving ahead.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐
tomatically decelerates, applies the brakes
lightly, or accelerates again if the vehicle ahead
begins moving faster.
As soon as the road is clear, the vehicle acceler‐
ates to the desired speed.
The speed is also maintained downhill, but may
not be maintained uphill if engine power is in‐
sufficient.General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Active cruise control is paused below approx.
20 mph/30 km/h.
The system does not brake to a stop.
Depending on the driving program, refer to
page 118, set, the characteristics of the cruise
control in particular areas can change.
Information WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. Based on the limits of the system,
it cannot independently react to all traffic situa‐
tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀

Objects in the area around the pedalsWARNING
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,
for example for cleaning. ◀
Driving in wet conditions When roads are wet, salted, or in heavy rain,
press brake pedal ever so gently every few
miles.
Ensure that this action does not endanger other
traffic.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills WARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system. ◀
WARNING
In idle or with the engine switched off,
safety-relevant functions are restricted or not
available anymore, for example braking effect
of the engine or braking force and steering
support. There is risk of an accident. Do not
drive in idle or with the engine switched off. ◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
needed.
Brake disc corrosion Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during brak‐
ing is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked vehicle When using the automatic climate control, con‐
densation water develops collecting under‐
neath the vehicle.
Ground clearance CAUTION
If ground clearance is insufficient, there
might be contact with the front or rear spoiler
for example when driving over curbs or enter‐
ing into underground car parking garages.
There is risk of property damage. Ensure that
there is sufficient ground clearance available. ◀
