The brakes function as usual again if:
R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to the maximum vehicle speed, adaptive
Brake Assist can react to moving obstacles
that have already been recognized as such at
least once over the period of observation.
Adaptive Brake Assist does not react to sta-
tionary obstacles.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R it is snowing or raining heavily
R there is interference from other radar sour-
ces
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle is traveling in front, e.g. a
motorbike
R a vehicle is traveling in front on a different
line
If adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the full brake boosting effect with the help of
BAS remains available.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. ASR (acceleration skid control)
General notes Important safety notes
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.
Vehicles without steering wheel buttons: if
ASR is malfunctioning, the
003Dindicator
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 221).
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 signifi-
cantly 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 with-
out 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 0072warning lamp in
the instrument cluster flashes.
Activating/deactivating ASR G
WARNING
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 brak-
ing automatically triggered by ESP ®
can
damage the brake system.
For this reason, deactivate ASR only briefly
and when absolutely necessary. 60
Driving safety systemsSafety
When ESP
®
is intervening and the 0072warn-
ing lamp in the instrument cluster is flashing,
leave ASR on. In this case, only depress the
accelerator pedal as far as required when
pulling away.
X Press the 00E3button.
If ASR is deactivated, the 0072warning
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:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ASR:
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels will then achieve a cutting effect for
better traction.
R traction 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.
R active brake intervention by ESP ®
to
increase driving stability remains active.
The 0072 warning lamp in the instrument
cluster flashes when ESP ®
is intervening. Emergency exit

Electrical step
The sliding door of your vehicle can be equip-
ped with an electrical access step.
X When getting in and out of the vehicle, use
the grab handles and electrical step 0043.
Electrical step 0043automatically extends
when the sliding door is opened and retracts
when it is closed.
Electrical step 0043is equipped with an
obstruction detection device on the front
side. If the step comes into contact with an
obstacle while it is extending, it stops.
After you have removed the obstacle, you
must first close the sliding door and open it
once again so that the step can extend com-
pletely.
i If the electrical step obstructs loading,
you can prevent the step from extending
when opening the sliding door via obstacle
detection. The electrical step can then
remain retracted and a forklift or other lift- ing equipment can be moved nearer to the
cargo compartment.
Vehicles without steering-wheel buttons: if
the 003E indicator lamp in the instrument
cluster lights up and a warning tone sounds,
electrical step 0043is malfunctioning
(Y page 230).
Vehicles with steering-wheel buttons: if the
Electrical Step
Electrical Step message is shown in the
display and a warning tone sounds, electrical
step 0043is malfunctioning (Y page 219).
If electrical step 0043is malfunctioning, the
step may only partially extend/retract or may
not extend/retract at all. If a malfunction
does occur, you will have to retract and lock
electrical step 0043manually before continuing
the journey (Y page 74).
Before passengers get out of the vehicle, let
them know that electrical step 0043might not
be extended. Emergency release
! Driving with the step extended may result
in it being damaged.
If the electrical step does not retract auto-
matically, you will have to push it in and
lock it into place manually before continu-
ing your journey. X

Important safety notes
G
WARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control
of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the engine. G
WARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the
seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat. G
WARNING
If head restraints are not installed and
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly. Observe the following points:
R
Position the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
R Your arms should be slightly bent when you
are holding the steering wheel.
R Avoid seat positions that prevent the seat
belt from being routed correctly. The
shoulder section of the belt must be routed
over the middle of your shoulder and be
pulled tight against your upper body. The
lap belt must always pass across your lap
as low down as possible, i.e. over your hip
joints.
R Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
Observe also the safety notes in the section
on "Air bags" (Y page 44) and "Children in the
vehicle" ( Ypage 50).
If you swap over the head restraints for the
front and rear seats, you will not be able to
adjust the height and angle of the head
restraints to the correct position.
Use the head restraint pad to adjust the head
restraint so that it is as close as possible to
the back of your head.
Before the journey, make sure the head
restraints have been correctly set for each of
the vehicle's passengers (Y page 86).82
