3Door released
The child-proof lock on the doors enable you to
secure each door individually.
A door with an activated child-proof lock cannot
be opened from the inside. If the vehicle is
unlocked, the door can be opened from the out-
side.
Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured
in the vehicle, they could press buttons or
switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
Driving safety systems
Overview
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lock Braking System)
RASR (Acceleration SkidControl)
RBAS (B rakeAssist System)
REBD (Electronic Brake Force Distribution)
RESP®(Electronic StabilityProgram)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of accident nor override the
laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed, braking in good time
and for staying in your lane. Always adapt your
driving style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry
Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 248).
ABS (Anti-lock Braking System)
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 54).
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.
54Driving safety systems
Safety
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 196).
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 54).
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 196).
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 awa
y 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.
For this reason, deactivate ASR only briefly
and when absolutely necessary.
When ESP®is intervening and the dwarning
lamp in the instrument cluster is flashing, leave
