Driving stability control systemsVehicle features and optionsThis 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
systems. The respectively applicable country
provisions must be observed when using the
respective 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.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
Automatic Differential Brake The system controls the driving force by auto‐
matic braking intervention on individual
wheels. The function corresponds to a differ‐
ential lock: the system detects if a wheel be‐
gins to spin, because of loose road surface,
e.g., and automatically brakes it.
The driving force is diverted to the wheel with
better traction.
As a result, the engine force is transferred
more efficiently to the wheels during accelera‐
tions.
Dynamic Performance
Control DPC
The Dynamic Performance Control increases
both the agility of the vehicle as well as the
lane stability.
The system seamlessly handles the distribu‐
tion of the drive torque between the two rear
wheels.
Depending on the situation, the drive torque is
shifted from the wheel on the inside of the

specific and optional features offered with the
series. It also describes features that are not

Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g. twice a
month and before a long trip.◀
Also check the tire inflation pressure of the
emergency wheel in the trunk regularly, and
correct it as needed.
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar, 2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 209, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 209, and adjust as necessary.

Online Edition for Part no. 01 40 2 963 464 - VI/15
These pressure values can also be found on
the tire inflation pressure label on the driver's
door pillar.
Do not exceed a speed of 100 mph/160 km/h.

Emergency wheel
Safety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.
Switch on the hazard warning system.▷Set the parking brake and engage lever in
position P P.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle or
portable hazard warning lamp at an appro‐
priate distance.▷Perform wheel change only on a flat, solid
and slip-resistant surface. On soft or slip‐
pery ground, e.g., snow, ice, tiles, etc., the
vehicle or vehicle jack can slip away to the
side.▷Do not place wood blocks or similar items
under the vehicle jack; otherwise, it cannot
reach its carrying capacity because of the
restricted height.▷If the vehicle is raised, do not lie under the
vehicle and do not start the engine; other‐
wise, a fatal hazard exists.
Information
WARNING
The vehicle jack is optimized for lifting
the vehicle and for the jacking points on the
vehicle only. There is risk of injuries. Do not lift
any other vehicle or cargo using the vehicle
jack.◀

sible.
Driving with emergency wheel
WARNING
The emergency wheel has particular di‐
mensions. When driving with an emergency
wheel, changed driving properties may occur
at higher speeds, e.g. reduced lane stability
when braking, longer braking distance and
changed self-steering properties in the limit
area. There is risk of an accident. Drive moder‐
ately and do not exceed a speed of
50 mph/80 km/h.◀
Vehicle battery Maintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
service life of the battery.
More information about the battery can be re‐
quested from a dealer’s service center or an‐
other qualified service center or repair shop.
Battery replacement CAUTION
Vehicle batteries that are not compatible
can damage vehicle systems and impair vehi‐
cle functions.There is risk of property damage.
Information on the compatible vehicle batteries
is available at your dealer's service center.◀
After a battery replacement, the manufacturer
of your vehicle recommends that the vehicle
battery be registered on the vehicle by a
dealer’s service center or another qualified
service center or repair shop to ensure that all
comfort features are fully available and that any
Check Control messages of these comfort fea‐
tures are no longer displayed.
Charging the battery
General information
Make sure that the battery is always suffi‐
ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.
Information
CAUTION
Battery chargers for the vehicle battery
can work with high voltages and currents,
which means that the 12V on-board network
can be overloaded or damaged. There is risk of
property damage. Only connect battery charg‐
ers for the vehicle battery to the starting aid
terminals in the engine compartment.◀
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 240, in the
engine compartment with the engine off.
Power failure
After a temporary power loss, some equipment
needs to be newly initialized or individual set‐
tings updated, e. g.:
▷Seat, mirror, and steering wheel memory:
store the positions again.▷Time: update.▷Date: update.▷Glass sunroof: initialize the system, refer to
