Seats
Seat adjustmentWarning!
G
All seat, head restraint adjustments, as well
as fastening of seat belts, must be done be-
fore 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 nearly upright position and
seat belts are properly positioned on the
body.
Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt
(page 395).
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 the
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 injury to per-
sons.
Warning!

in an accident and/or serious personal
injury.
