Points to remember
For information about folding the rear bench
seat forwards, see the "Luggage compart-
ment enlargement" section (Y page 132).
Depending on the vehicle's equipment, the
seats can adjusted either manually/electri-
cally or electrically*. 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.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 40). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
The rear-compartment head restraints can
be removed (Y page 64).

Steering wheel
Points to remember
Depending on the vehicle equipment, you can
adjust the steering wheel either manually or
electrically*. 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 Adjusting the steering wheel man-

Easy-entry/exit feature*
The easy-entry/exit feature makes getting in
and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock
R open the driver's door when the key in the
ignition lock is in position 0or 1.
When the key is inserted into the ignition lock
with the driver's door closed, the steering
wheel is automatically moved to the previ-
ously set position. 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 becoming trapped, stop the
adjustment procedure. To halt the procedure:
R press the steering-column adjustment
switch
R press one of the memory function position
buttons
The steering column stops moving immedi-
ately.
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 most recent position of the steering
wheel is stored when you switch off the igni-
tion or when you store a memory position
(Y page 69).
You can activate and deactivate the easy-
entry/exit feature via the on-board computer
(Y page 104). Mirrors

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. Mirrors
