38 Getting startedAdjustingSeats
The seats can be adjusted either manually 
or electrically, depending on the vehicle’s 
equipment.
For more information, see “Seats” 
(page 104).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 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 47).
Never place hands under the seat or near 
moving parts while the 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 op-
erated 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.

pervised use of vehicle equipment may 
cause an accident and/or serious personal 
injury.
!Do not drive the vehicle until you have 
properly locked the steering column.Warning!
G
Only adjust the steering wheel with the vehi-
cle at a standstill and make sure the steer-
ing column is securely locked in place 
before driving off.
Driving without the steering column locked 
may cause an unexpected steering wheel 
movement which could cause the driver to 
lose control of the vehicle. Make sure the 
steering column is securely locked by trying 
to move it up and down, and in and out be-
fore driving off.

in mind that a considerably higher degree of 
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or 
leaves can come into contact with the hot 
exhaust system, as these materials could be 
ignited and cause a vehicle fire.
