Points to remember
G
Risk of injury
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could become trapped when
adjusting a seat. G
Risk of accident
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
Risk of injury
Make sure that nobody can become trapped
when you adjust the seat.
Observe the notes concerning the airbag sys-
tem.
Secure children as recommended; see "Chil-
dren in the vehicle" section. G
Risk of injury
Make sure that the central area of the head
restraint supports the back of your head at
about eye level. You could seriously injure
your neck if your head is not correctly sup-
ported by the head restraint in the event of an
accident. Never travel without a correctly
adjusted and engaged head restraint.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.

Risk of injury
When adjusting a front-passenger seat that is
occupied, make sure that it is as far away from
the front-passenger airbag as possible. The
front passenger could otherwise sustain seri-
ous or fatal injuries in the event of an accident
or braking manoeuvre.
Make sure that nobody can become trapped
when adjusting the seat.
The front-passenger seat can be adjusted
when there is no key in the ignition lock. For
this reason, children should never be left
unsupervised in the vehicle. They could
become trapped if the seats move.
You can use the seat switches on the driver's
side to adjust the front-passenger seat. 184

ment G
Risk of injury
On a seat which is occupied, pull the head
restraint up into the upright position. This
reduces the risk of injury to the passenger in
the event of an accident. G
Risk of injury
Make sure that nobody can become trapped
when folding the head restraints up or back.

Points to remember
G
Risk of injury
The electrically adjustable steering wheel can
be adjusted when the key is removed from the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle as they could
become trapped as the steering wheel is
adjusted. G
Risk of accident
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. Otherwise, you might drive
without the steering wheel adjustment mech-
anism being locked in position and be distrac-
ted from road and traffic conditions by an
unexpected movement of the steering wheel
and cause an accident.
However, the steerability of the vehicle is not
affected.
When you adjust the steering wheel, make
sure that:
R the steering wheel can be reached with
your arms slightly bent
R you can move your legs freely
R you can see all the displays in the instru-
ment cluster clearly Steering wheel

The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier. The steering wheel tilts upwards and the driv-
er's seat slides back if you:
R remove the key from the ignition lock
R open the driver's door when the key is in
the ignition lock or in position 1
i The steering wheel only moves upwards
if it has not already reached the upper end
stop. The driver's seat only moves back-
wards if it is not already in the rearmost
position.
If you insert the key into the ignition with the
driver's door closed, the position of the steer-
ing wheel and the driver's seat will be
changed to the last selected position.
i The adjustment procedure stops when
you begin driving. G
Risk of injury
Make sure that nobody can become trapped
when you activate the EASY-ENTRY/EXIT fea-
ture.
If there is a risk of entrapment by the steering
column, move the steering wheel adjustment
lever or press the position button of the mem-
ory function.
If there is a risk of entrapment by the seat, you
can also cancel the adjustment procedure by
moving the seat adjustment switch. The steer-
ing column and driver's seat* stop moving
immediately.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and,
thereby, unintentionally activate the EASY-
ENTRY feature and become trapped.
The last driving position of the steering wheel
or the seat is saved if:
R the ignition is switched off
or
R a memory position is stored.

lock. This makes it easier to exit the vehicle
or rescue the occupants. Mirrors
Exterior mirrors
G
Risk of accident
The exterior mirrors reduce the size of the
image. Objects are actually closer than they
appear. You could misjudge the distance from
vehicles driving behind and cause an acci-
dent, e.g. when changing lane. For this rea-
son, make sure of the actual distance from the
vehicle driving behind by glancing over your
shoulder.
The convex exterior mirrors provide a larger
field of vision.
At low outside temperatures the exterior mir-
rors are heated automatically. Adjusting the exterior mirrors
