sumers, such as seat adjustment*
2Ignition (power supply for all electrical 
consumers) and driving position
All lamps (except high beam headlamp 
indicator 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, see “Lamps in 
instrument cluster” (
page 348).
3Starting position
!A side window will not work if it is blocked 
with ice or if the battery needs charging. If you 
cannot shut a door, do not force it or you could 
damage the door or the side window. 
Fix whatever is affecting the window before 
trying to shut the door.
iWithout the antenna on the left rear side 
of the vehicle installed, the SmartKey signaling 
range is considerably reduced. 
Hold the SmartKey in close proximity towards 
the antenna base when locking or unlocking 
the vehicle.
Warning!G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you, and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. 
A child’s unsupervised access to a vehicle 
could result in an accident and/or serious 
personal injury.

38 Getting started
Unlocking
For information on starting the engine, see 
(
page 51).
iWhen you switch on ignition, the indicator 
and warning lamps (except high beam headlamp 
indicator lamp and turn signal indicator lamps 
unless activated) in the instrument cluster come 
on. The indicator and warning lamps (except high 
beam headlamp indicator lamp and turn signal 
indicator lamps if activated) will go out when the 
engine is running. This indicates that the respec-
tive 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 
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.
!If the SmartKey cannot be turned in the 
starter switch, the vehicle battery may not be 
sufficiently charged.
Check the vehicle battery and charge it if 
necessary (
page 422).
Get a jump start (page 426).
To prevent accelerated vehicle battery discharge 
or a completely discharged vehicle battery, 
always remove the SmartKey from the starter 
switch when the engine is not in operation.

Adjusting
Adjusting
Seats
The seats can be adjusted either manually 
or electrically, depending on the vehicle’s 
equipment.
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 seat belt would apply force at 
the abdomen or neck. That could cause se-
rious 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 posi-
tioned on the body.
Your seat must be adjusted so that you can 
correctly fasten your seat belt (
page 48).
Observe the following points:
Adjust the seat backrest until your arms 
are slightly angled when holding the 
steering wheel.
Adjust 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.
Adjust 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.
Never place hands under the seat or 
near any moving parts while a seat is 
being adjusted.
Failure to do so could result in result in an 
accident and/or serious personal injury.

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 op-
erated when the respective door is open. 
Therefore, do not leave children unattended 
in the vehicle, or with access to an unlocked 
vehicle. A child’s unsupervised access to a 
vehicle could result in an accident and/or 
serious personal injury.
Warning!G
Children 12 years old and under must be 
seated and properly secured in an appropri-
ate 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 79).
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 there are 
no items in the footwell or behind the seats; 
otherwise you could damage the seats.
