Seats
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.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate
controls properly.

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.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
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 unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.

forward and upward movement.
!When moving the seat, make sure there are
no items in the footwell or behind the seats. Oth-
erwise you could damage the seats.

the backrest locked in place. Therefore, the
backrest must be locked in place with the
vehicle in motion. Do not drive the vehicle
when the backrest is not locked in place.

pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment
procedure.

ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.

SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
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,
