Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 247).
ABS (Anti-lock Braking System)
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 52).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems will also
fail, including driving safety systems. Observe
the information relating to the !warning
lamp (
Ypage 195).
ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you
only brake gently.
The yellow !warning lamp in the instrument
cluster lights up when the ignition is switched
on. The lamp goes out when the engine starts
running.
Braking
If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions and functions as a
reminder to take extra care while driving.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.
ASR (acceleration skid control)
General notes
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 52).
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or
accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road and
weather conditions.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ASR will be deacti- vated for the duration of the activation/deacti-
vation process.
Vehicles without steering wheel buttons: if ASR
is malfunctioning, the :indicator lamp lights
up while the engine is running and the engine
power may be reduced (
Ypage 195).
ASR significantly improves traction, i.e. the
transmission of power from the tires to the road surface, and thus increases the vehicle's driving
stability. If the driving wheels start to spin, ASR
brakes individual drive wheels and limits the
engine torque. ASR thus significantly assists you
when pulling away and accelerating, especially
on wet or slippery roads.
If traction on the road surface is not sufficient,
even ASR will not allow you to pull away without
difficulty. The type of tires and total weight of the
vehicle as well as the gradient of the road also
play a crucial role.
If ASR intervenes, the dwarning lamp in the
instrument cluster flashes.
Activating/deactivating ASR
GWARNING
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel- eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
!If you deactivate ASR, ESP®will still inter-
vene to stabilize the vehicle. Frequent braking
automatically triggered by ESP
®can damage
the brake system.
Driving safety systems53
Safety
Z
For this reason, deactivate ASR only briefly
and when absolutely necessary.
When ESP®is intervening and thedwarning
lamp in the instrument cluster is flashing, leave
ASR on. In this case, only depress the acceler-
ator pedal as far as required when pulling away.
XPress the àbutton.
If ASR is deactivated, the dwarning lamp
in the instrument cluster lights up.
ASR is automatically activated when the engine
is started.
It may be best to deactivate ASR briefly in the
following situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
If you deactivate ASR:
Rengine torque is not limited and the drive
wheels are able to spin. The spinning wheels
will then achieve a cutting effect for better
traction.
Rtraction control remains active through brake
intervention. If a drive wheel attains its tire
traction limit because one side of the road is
slippery, for example, that wheel is braked.
The traction is then increased in this situation.
Ractive brake intervention by ESP®to increase
driving stability remains active. The d
warning lamp in the instrument cluster
flashes when ESP
®is intervening.
BAS (Brake Assist System)
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if the
BAS driving safety system is malfunctioning,
the : warning lamp lights up while the
engine is running (
Ypage 195).
BAS operates in emergency braking situations.
If you depress the brake quickly, BAS automat-
ically increases the brake pressure, thereby
reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
EBD (electronic brake force distribu-
tion)
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Observe the information on warning and indica-
tor lamps (
Ypage 195).
ESP®(Electronic Stability Program)
Important safety notes
GWARNING
If ESP
®is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®checked at a qualified specialist
workshop.
!Do not run the vehicle on a roller dynamom-
eter (e.g. for performance tests). If you must
operate the vehicle on a roller dynamometer,
54Driving safety systems
Safety
please consult a qualified specialist workshop
in advance. You could otherwise damage the
drive train or the brake system.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ESP
®will be deac-
tivated for the duration of the activation/deac-
tivation process.
If ESP
®is malfunctioning, the hindicator
lamp lights up while the engine is running and
the engine power may be reduced
(
Ypage 194).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
4ETS (Electronic Traction System)
!A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
4ETS is only active when all-wheel drive is acti-
vated (
Ypage 148).
4ETS ensures permanent drive for all four
wheels, and together with ESP
®it improves the
vehicle's traction.
If a driven wheel spins due to lack of traction:
RWhen pulling away, make use of the traction
control integrated in ESP®. Depress the
accelerator pedal as far as necessary.
RWhile driving, slowly take your foot off the
accelerator pedal.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 249). This is the only way to get the full
benefit from the all-wheel drive system.
Crosswind Assist
Crosswind Assist does not work if ESP®is deac-
tivated or disabled because of a malfunction.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
as a result of uneven surfaces or potholes
Rif the vehicle loses traction, e.g. on snow or
ice or when aquaplaning
Rto large and sudden steering movements by
the driver Crosswind Assist is operational again as soon as
the driving conditions return to normal.
Crosswind Assist detects strong crosswind
gusts that can impair the road holding of your
vehicle when driving straight ahead. Crosswind
Assist intervenes depending on the direction
and strength of the crosswind.
A stabilizing brake application helps you to keep
the vehicle on track.
Information appears in the instrument cluster In the event that Crosswind Assist intervenes
noticeably.
On vehicles without steering wheel buttons:
the d indicator lamp in the instrument clus-
ter flashes.
On vehicles with steering wheel buttons: the
d indicator lamp in the instrument cluster
flashes and the message Crosswind Assist
Activeappears in the multifunction display.
Crosswind Assist is active above a vehicle speed
of 50 mph (80 km/h) when the vehicle is driving
straight ahead or cornering gently.
Emergency exit
Emergency exit window
GWARNING
The emergency exit window cannot be locked in place. You risk injury if you exit the vehicle
through the emergency exit window.
RMake sure that nobody becomes trapped,
both when closing and when opening the
emergency exit window.
RThe opened emergency exit window must
be held in place by another person.
Pay attention to traffic conditions.
GWARNING
If the emergency exit window is unlocked
while driving, it could open and slam shut and consequently fall down. There is a risk of an
accident and injury.
Before starting off, make sure that the emer-
gency exit window is locked and the locking
pins are undamaged.
!Make sure there is sufficient clearance
when opening the emergency exit window.
