The doors and the tailgate lock automati-
cally when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.For information on towing the vehicle, see
“Towing the vehicle” (
page 518).
You can deactivate the automatic locking
mode using the control system
(

Locking and unlocking from the inside
You can lock or unlock the doors and the
tailgate from inside using the central lock-
ing or unlocking switch. This can be useful,
for example, if you want to lock the vehicle
before starting to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking or unlock-
ing switch.
i
To prevent a possible inadvertent lockout,
the tailgate will open automatically if a SmartKey
with KEYLESS-GO* is recognized inside the
vehicle.

The doors unlock automatically after an
accident if the force of the impact exceeds a
preset threshold.
The vehicle automatically locks when the ignition
is switched on and the wheels are turning at

Rear seat head restraints
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is 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.
Warning!
G
Do not drive the vehicle without the seat
head restraints installed when the rear seats
are occupied. Head restraints are intended
to help reduce injuries during an accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the oc-
cupant adjust the head restraint properly.
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way 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 re-
duce the potential for injury to the head and
neck in the event of an accident or similar
situation.
134 Controls in detailMemory function*Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach and comfort. The head
restraint should also be adjusted for
proper height. See also the section on
air bags (
page 71) for proper seat posi-
tioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small chil-
dren should be seated in a properly se-
cured restraint system that complies with
U.S. Federal Motor Vehicle Safety Stan-
dard 213 and 225 and Canadian Motor Ve-
hicle Safety Standards 213 and 210.2.With the memory function you can store up
to three different settings for each front
seat.
The following settings are saved for each
stored position on the entry side of the
driver’s seat:
Driver’s seat, head restraint height and
backrest position
Steering wheel position
Driver’s side exterior rear view mirror
position
Passenger-side exterior rear view
