Vehicle Damage Warnings
Also, in this book you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You’ll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specic component, control,
message, gage or indicator.

component, gage or indicator, reference the following

Section 1 Seats and Restraint Systems
1-1

Front Seats
Manual Seats
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal
when you don’t want to. Adjust the driver’s
seat only when the vehicle is not moving.
Lift the bar located under the front of the passenger’s
seat to unlock the seat. Slide the seat to the desired
position and release the bar. Try to move the seat to be
sure it is locked into place.
1-2

Six-Way Power Seats
If the vehicle has a driver’s
side power seat, the
control for it is located on
the outboard side of
the seat cushion.
To move the seat forward or rearward, push the
control forward or rearward.
To raise or lower the entire seat, push the control
up or down.
To raise or lower the front of the seat, push the
front of the control up or down.
To raise or lower the rear of the seat, push the rear
of the control up or down.
Reclining Seatbacks
Lift the lever located on the outboard side of the seat to
release the seatback, then move the seatback to the
desired position. Release the lever to lock the seatback
in place. Pull up on the lever without pushing on the
seatback and the seatback will move forward.
1-3

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
Rear Seats
Split Folding Rear Seat
If the vehicle has a split folding seat, you can gain
access to the interior of the vehicle through the trunk.
To do this, pull forward
on the seat tab, located
on the side of the rear
seat, to move the
rear seatback down.
To return the seatback to its original position, push it
back up, making sure the seat latch locks it in place.

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:
Don’t let anyone ride where he or she can’t
wear a safety belt properly. If you are in a
crash and you’re 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.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-30.
1-6

Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn’t long enough, seeSafety Belt
Extender on page 1-27.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
