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 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
For your protection, drive only with properly 
positioned head restraints.
Adjust head restraint so that the head 
restraint supports the back of the head at 
eye level. This will reduce the potential 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 in-
tended to help reduce injuries during an 
accident.
iAdjust the head restraint in such a way that 
it is as close to the head as possible.

Mirrors
Adjust the interior and exterior rear view 
mirrors before driving so that you have a 
good view of the road and traffic condi-
tions.

for a wider field of view). Objects in mirror 
are closer than they appear. Check your in-
terior rear view mirror or glance over your 
shoulder before changing lanes.
!If an exterior rear view mirror housing is 
forcibly pushed forward (hit from the rear) or 
rearward (hit from the front), reposition it by 
applying firm pressure until it snaps into place. 
The exterior rear view mirror housing is now 
properly positioned and you can adjust the 
mirror in the usual manner.
