Manual Seats
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle

when you do not want to. Adjust the driver’s
seat only when the vehicle is not moving.
Your vehicle has manual seats. Lift the bar located
under the front of the seat to unlock it. Slide the seat to
where you want it and release the bar. Try to move
the seat with your body to be sure the seat is locked in
place.

Your vehicle may have heated front seats. This feature
heats the seat cushions. The switches are located on the

indicator lights to turn on
the heated seat at the

indicator light to go to the low setting. The indicator light
will be lit to indicate that the setting is on low. Return
the switch to the center to turn off the heated seat.

setting will be retained when the vehicle is started again.

{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.But do not have a seatback reclined if your vehicle is
moving.{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job because it
will not be against your body. Instead, it will be
in front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt cannot do its job either. In a crash
the belt could go up over your abdomen. The
belt forces would be there, not at your pelvic
bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.

If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
pull forward on the top of the seatback at the

{CAUTION:
A safety belt that is improperly routed, not

the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.
Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she can not
wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers’ belts are
fastened properly too.
