3Starting position
When you switch on the ignition, all lamps in
the instrument cluster come on. The low-
beam headlamp indicator lamp, high-beam
headlamp indicator lamp, and turn signal
indicator lamps will only come on if activated.
If a lamp in the instrument cluster fails to
come on when the ignition is switched on,
have it checked and replaced if necessary. If
a lamp in the instrument cluster remains on
after starting the engine or comes on while
driving, refer to “Lamps in instrument cluster”
(Y page 219).
If the SmartKey is left in starter switch
position 0 for an extended period of time, it
can no longer be turned in the starter switch.
In this case, the steering is locked. To unlock,
remove SmartKey from the starter switch and
reinsert.
The steering is locked when the SmartKey is
removed from the starter switch.
XAlways remove the SmartKey from the
starter switch when the engine is not in
operation.
This will help to prevent accelerated vehicle
battery discharge or a completely
discharged vehicle battery.
If the SmartKey cannot be turned in the
starter switch, the vehicle battery may not be
sufficiently charged.
XCheck the vehicle battery and charge it if
necessary (Y page 244).

Safety notes
GWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
Rseat adjustment
Rhead restraint adjustment
Rsteering wheel adjustment
Rrear view mirror adjustment
Rfastening of seat belts
GWarning!
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.

GWarning!
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
RAdjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
RAdjust 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.
RAdjust 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.
RNever 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.
GWarning!
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.
GWarning!
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.

Rear seat head restraintsGWarning!
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
GWarning!
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 reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
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.
