dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.

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 (E lectronic 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.
52Driving safety systems
Safety
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.

erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rthe water level of standing water should not
be above the lower edge of the front bumper
Rdo not drive faster than walking speed
Driving in winter
General notes
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop in good time at the onset of
winter.
iDo not cover the radiator, e.g. with a winter
cover. The measurements of the on-board
diagnostic system may otherwise return inac-
curate values. Some of these values are
legally prescribed and must therefore always
be exact. Observe the notes in the "Winter operation" sec-
tion (
Ypage 249).
Slippery road surfaces
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GWARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N. Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to neutral position N.
XTry to maintain control of the vehicle using
corrective steering.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.
You can find further information on winter tires
and snow chains in the "Winter operation" sec-
tion (
Ypage 249).
