Safety Warnings and Symbols
There are a number of safety cautions in this book. We
use a box and the word CAUTION to tell about things
that could hurt you if you were to ignore the warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is.
Then we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you do not,
you or others could be hurt.
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Do Not,”
“Do Not do this” or
“Do Not let this happen.”
iii

Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice: These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell 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.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specific component, control, message,
gage, or indicator.
If you need help figuring out a specific name of a
component, gage, or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages, and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

These are some examples of symbols that may be found on the vehicle:

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 do not want to. Adjust the driver’s
seat only when the vehicle is not moving. If your vehicle has a manual bucket or a split bench
seat, you can adjust the seat forward or rearward with
the bar located under the front of the seat cushion.
Lift the bar to unlock the seat. 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.
1-3

Power Seats
If your vehicle has power seats, the controls are located
on the outboard side of the seats.
•Raise or lower the front of the seat cushion by
raising or lowering the front of the horizontal control.
•Raise or lower the rear of the seat cushion by
raising or lowering the rear of the horizontal control.
•Raise or lower the entire seat cushion by raising or
lowering the whole horizontal control.
•Move the seat forward or rearward by moving the
horizontal control forward or rearward.
If your vehicle has power reclining seatbacks, the
control is located rear of the power seat control on the
outboard side of the seats. Adjust the angle of the
seatback by pressing the vertical control forward
or rearward. See Reclining Seatbacks on page 1-6.
If your vehicle has manual reclining seatbacks,
see Reclining Seatbacks on page 1-6.
Power Lumbar
Your vehicle may have this feature.
The control is located
on the outboard side
of the seat cushion.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your seating
position changes, as it may during long trips, so
should the position of your lumbar support. Adjust the
seat as needed.
1-4

Heated Seats
If your vehicle has this
feature, the buttons are
located on the front doors.
The engine must be
running for the heated
seats to work.
To heat the entire seat, press the horizontal button
with the heated seat and seatback symbol. Press the
button to cycle through the temperature settings of
high, medium and low and to turn the heated seat off.
Indicator lights will be lit to designate the level of
heat selected: three for high, two for medium, and
one for low.
To heat only the seatback, press the vertical button
with the heated seatback symbol. An indicator light on
the seatback button will be lit to designate that only
the seatback is being heated. Additional presses of the
seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again to
heat the whole seat.
The heated seats will be canceled after the ignition is
turned off. If you still want to use the heated seat feature
after you restart your vehicle, you will need to press
the heated seat button again.
1-5

Reclining Seatbacks
{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 push and pull on the seatback to be
sure it is locked.
To adjust the seatback, lift the manual lever located
on the outboard side of the seat. Release the
lever to lock the seatback in the desired position.
Lift the lever again without pushing on the seatback
and the seatback will go to an upright position.
If your vehicle has power seats with a power recliner,
see Power Seats on page 1-4 for further information on
how to operate the reclining seatback feature.
1-6

{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. 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.
Do not have a seatback reclined if your vehicle is moving.
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.
Pull the head restraint up to raise it. Push the head
restraint down to lower it.
Your rear seats may have head restraints that can be
adjusted up and down.

the cushion, try moving the front seat forward and/or
bring the front seatback more upright.
Once the seatbacks are folded forward, on extended
models only, the rear seat footwell area will be exposed
and will have to be covered by the load floor panels.
To create a load floor, do the following:

forward on the latches.
2. Fold the panels back to cover the rear seat
footwell area.

to be sure that the safety belts are properly
routed and attached, and are not twisted.
