consumers) and driving position.
All lamps (except low beam headlamp
indicator lamp, high beam headlamp in-
dicator lamp, and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. 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 re-
mains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (page 322).
3Starting position
iWhen you switch on ignition, the indicator
and warning lamps (except low beam headlamp
indicator lamp, high beam headlamp indicator
lamp, and turn signal indicator lamps unless ac-
tivated) in the instrument cluster come on. The
indicator and warning lamps (except low beam
headlamp indicator lamp, high beam headlamp
indicator lamp, and turn signal indicator lamps if
activated) will go out when the engine is running.
This indicates that the respective systems are
operational.
iVehicles with automatic transmission*:
The SmartKey can only be removed from the
starter switch with the gear selector lever in
positionP.
iIf the SmartKey is left in starter switch
position0 for an extended period of time, it can
no longer be turned in the switch. In this case,
the steering is locked. To unlock, remove
SmartKey from starter switch and reinsert.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be sufficient-
ly charged.

Check the battery and charge it if necessary
(
page 383).

Get a jump start (page 386).
To prevent accelerated vehicle battery discharge
or a completely discharged battery, always re-
move the SmartKey from the starter switch when
the engine is not in operation.

34 Getting started
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information, see “Seats”
(
page 101).
Warning!G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!G
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
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat back and seat belts
provide the best restraint when the wearer
is in a nearly upright position and belts are
properly positioned on the body. Your seat
must be adjusted so that you can correctly
fasten your seat belt (
page 43).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the power seats* can be
operated when the respective door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing 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
appropriate infant, or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional
information, see “Children in the vehicle”
(
page 74).
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.
!When moving the seats, make sure that
there are no items in the footwell or behind the
seat. Otherwise you could damage the seats.

removed while in their liquid state and by apply-
ing plenty of water.
