Pressing the KEYLESS-GO start/stop but-
ton on the gear selector lever corresponds
to turning the SmartKey to the various
starter switch positions.
If you firmly depress the brake pedal dur-
ing pressing the KEYLESS-GO start/stop
button, the engine starts automatically.
iWhen you switch on the ignition, the in-
dicator and warning lamps (except low
beam headlamp indicator lamp, high
beam headlamp indicator lamp, and
turn signal indicator lamps unless acti-
vated) 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) should go out when the en-
gine is running. This indicates that the
respective systems are operational.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in position P.

starter switch, the starter battery may
not be sufficiently charged.
Check the battery and charge it if

40 Getting startedAdjustingSeatsWarning!
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
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 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 47).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the start-
er switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
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. Unsu-
pervised use of vehicle equipment 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. Re-
gardless 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 recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 78).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

42 Getting startedAdjustingHead restraint height
Press the switch up or down in direc-
tion of arrow1.Head restraint tilt
Manually adjust the angle of the head re-
straint.
Push or pull on the lower edge of the
head restraint cushion.
For more information on seats, see the
“Controls in detail” section (
page 131).
Steering wheel
iAdjust the head restraint in such a way
that it is as close to the head as possi-
ble.Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial 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 intend-
ed to help reduce injuries during an acci-
dent.
iAdjust the head restraint in such a way
that it is as close to the head as possi-
ble.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the start-
er switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the steering wheel adjustment feature can
be operated when the driver’s 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.
