R
Adjust the head restraint so that it is as
close
to the head as possible. The center of
the head restraint must support the back of
the head at eye level.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury. G
Warning!
The power seats can be operated at any time.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury. G
Warning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children

be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint. G
Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust

the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation. Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident.
Seat adjustment
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items.
Power seats !
When the second-row seats are folded
forward, e.g. for cargo volume expansion,
the front seats may not be moved to the
rearmost position. Otherwise you could
damage the front and second-row seats.
! When

adjusting the seat backrest tilt and
head restraint height, make sure the sun
visor is folded up. If the head restraint is in
the uppermost position, it could hit and
damage the sun visor.
i Vehicles without memory function:
The seats can be adjusted within 5 minutes
after either front door has been opened.
The counter resets each time
R you open or close a front door
R you insert the SmartKey into the starter
switch
R you remove the SmartKey from the
starter switch
R you switch the ignition on or off
Just like in vehicles with memory function,
the power seats can be operated at any
time when the ignition is switched on.
i The memory function (Y page 96) lets
you store the settings for the seat position
together with the settings for the steering
wheel (electrical) and exterior rear view
mirrors. 82

G
Warning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the parking brake in addition
to shifting the automatic transmission into
park position P.
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.
X Depress the brake pedal.
X Shift the automatic transmission into drive
position D or reverse gear R.
X Release the brake pedal.
X Carefully depress the accelerator pedal.

control is beneficial because it keeps the vehicle level at the rear axle constant,
independent of the load.

Observe the information on towing a
trailer, see “Trailer towing” ( Y page 256). AIRMATIC
The AIRMATIC lets you select the chassis and
suspension setup. The chassis and
suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The AIRMATIC consists of two components.
The Adaptive Damping System (ADS)
(Y page 153) and the vehicle level control
(Y page 154). Adaptive Damping System (ADS)
The Adaptive Damping System (ADS) is
controlled electronically and operates
continuously. It adjusts the damping
characteristics to the current operating and
driving conditions. The damping is adjusted
individually for each wheel. Driving safety and
tire comfort are increased.
The fine tuning of the damping is dependent
on:
R your driving style
R road surface conditions
R your personal settings The following settings are available:

X Start the engine.
X Press ADS switch : repeatedly until the
desired suspension tuning is reached.
The setting remains stored when you turn off
the engine. Vehicle level control
Your vehicle automatically adjusts its ride
height.
The all-around vehicle level control provides
best possible suspension and constant
ground clearance. The vehicle lowers at high
speed automatically in order to increase
driving safety and to reduce fuel
consumption.
Changes to the vehicle level should be made
while the vehicle is moving. The vehicle will
then reach the set level as fast as possible.
When you park the vehicle and the ambient
temperature changes, the vehicle level may
change visibly. When the temperature drops,
the vehicle lowers. When the temperature
rises, the vehicle raises.
The vehicle begins adjusting to the set vehicle
level as soon as the doors or tailgate are
unlocked or opened or closed with the vehicle
unlocked.
For major changes in vehicle level, the engine
must be running. G
Warning!
Make sure no one is near the wheel housing
or under the vehicle when you lower the
vehicle while it is standing still. Limbs could
become wedged into or under the vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate closed.
Lowering is interrupted if a door or the tailgate is opened and will continue after the door is
closed again.
! Keep in mind that on rough or uneven
roads, adjusting the vehicle to a lower level
may cause the vehicle underbody to come
in contact with the road and result in
damage to the vehicle underbody. Always
make sure the vehicle has sufficient ground
clearance before adjusting it to a lower
level.
! Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.
