Safety notes
G
Warning!
In order to avoid possible loss of vehicle
control
the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts G
Warning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle. Never ride in a moving vehicle with the seat
backrest
in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body. G
Warning!
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust
the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
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!
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 section “Children in the
vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints 62

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
The seats can be adjusted either manually or
electrically, depending on the vehicle’s
equipment.
! 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.
Manual seat adjustment X
Seat fore and aft adjustment: Pull
handle :.
X Slide the seat to the desired position.
X Allow handle : to reengage with an
audible click. X
Check for proper engagement before
driving.
X Seat height: Pull or push handle ; up or
down and adjust the seat height until your
legs are lightly supported.
X Seat backrest tilt: Pull handle = and
adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
X Release handle = when the desired seat
backrest tilt is reached.
When you hear an audible click, the seat
backrest is again fixed into place.
Power seats 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.

Easy-entry/exit feature
This feature allows the driver an easier entry
into and exit from the vehicle. When entering
and exiting the vehicle, the steering wheel is
in its uppermost position.
The easy-entry/exit feature can be activated
or deactivated in the Convenience submenu
of the control system (Y page 108). G
Warning!
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement do one of
the following:
R Move steering wheel adjustment stalk.
R Press one of the memory position buttons.
R Press memory button M.
Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you close the driver’s door with
the ignition switched on. The steering wheel
will also return to its last set position when
you insert the SmartKey into the starter
switch.
i The last set steering wheel position is
stored when the ignition is switched off or
the position is stored in memory
(Y page 70).
With the easy-entry/exit feature activated,
the steering wheel tilts upwards when you
remove the SmartKey from the starter switch. The steering wheel also tilts upwards when
you open the driver’s door with the SmartKey
in starter switch position
0 or 1.
i When the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will no longer be able to
move upward when the easy-entry/exit
feature is activated.
The adjustment procedure is briefly
interrupted when the engine is started. G
Warning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All steering wheel adjustment must
be completed before setting the vehicle in
motion. Driving off with the steering wheel
still adjusting could cause the driver to lose
control of the vehicle.
Crash-responsive exit aid When you open the driver’s door after an
accident has occurred, the steering column
moves up. The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
occupants.
The crash-responsive exit aid can only be
triggered when the easy-entry/exit feature is
activated via the control system.
