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

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 do not want to. Adjust the driver’s
seat only when the vehicle is not moving. 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.
1-2

Six-Way Power Seats
Your vehicle may have
this feature. If it does,
the six-way power
seat control is located
on the outboard side
of the driver’s seat. Your
vehicle may also have
a passenger’s six-way
power seat.
•Move the front of the control up or down to adjust
the front portion of the cushion up or down.
•Move the rear of the control up or down to adjust
the rear portion of the cushion up or down.
•To move the whole seat forward or rearward, slide
the control forward or rearward.
Power Lumbar
If your vehicle has this
feature, the control is
located on the outboard
side of the seat(s).
Press and hold the front of the control until you have
the desired lumbar support. To decrease lumbar
support, press and hold the rear of the control.
1-3

Heated Seats
If your vehicle has this
feature, the controls are
located on the outboard
side of the front seats.
This feature will heat the cushion and back of the seats.
Press the top of the switch to turn the heat to the
high setting. Press the bottom of the switch to turn the
heat to the low setting. Put the switch in the center
position to turn the heat off.
The ignition must be on for the heated seat feature to
work. The seat will heat to the last setting if the ignition
has been turned off and then turned back on.
The passenger’s safety belt must be engaged for the
heated seat feature to work on the passenger’s seat.
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.
Your seats have manual reclining seatbacks. The lever
used to operate them is located on the outboard
side of the seats.
1-4

To recline the seatback, do the following:
1. Lift the recline lever.
2. Move the seatback to the desired position, then
release the lever to lock the seatback in place.
3. Push and pull on the seatback to make sure it is
locked.
To return the seatback to an upright position, do the
following:
1. Lift the lever fully without applying pressure to the
seatback and the seatback will return to the upright
position.
{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.
2. Push and pull on the seatback to make sure it is
locked.
1-5

{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.
Do not have a seatback reclined if your vehicle is moving.
1-6

Head Restraints
Adjust the head restraint so that the top of the restraint
is at the same height as the occupant’s head. This
position reduces the chance of a neck injury in a crash.
Pull the head restraint up
to raise it. To lower the
head restraint, press
the button, located on
the top of the seatback,
and push the head
restraint down.
1-7

Rear Seats
60/40 Split Bench Seat
The 60/40 split bench seats can be folded to give you
more cargo space.
Folding the Seatbacks
To fold the rear seatback(s), do the following:
1. Make sure that nothing is on, under, or in front of
the seat.
2. Place your hand under
the front of the seat
cushion and lift
the cushion up while
moving it forward.
There is a label below
the seat cushion
with instructions to
aid in seat operation.
3. Pull the cushion forward until it rests in the footwell.
Notice: Folding a rear seat with the safety belts
still fastened may cause damage to the seat or
the safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
1-8

4. Lift the latch on top of the seatback and pull the
seatback forward. Fold the seatback down until it
is nearly flat.
5. If the seatback will not fold nearly flat, try moving
the front seat forward and/or moving the front
seatback more upright.
6. Repeat the steps for the other half of the 60/40 split
bench seat.
1-9

Returning the Seatbacks to an
Upright Position
{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.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
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.
To return the seatback(s) to the upright position, do the
following:
1. Lift the seatback up and push it rearward all the way.
2. Place your hand under the front of the seat cushion
and lift the cushion while moving it rearward until it
latches into position.
3. Pull forward on the seatback and push down on the
seat cushion to make sure the seat is securely in
place.
1-10

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 cannot
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.
{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 indicators to remind you and your
passengers to buckle your safety belts. See Safety Belt
Reminder Light on page 3-27 and Passenger Safety
Belt Reminder Light on page 3-27.
1-11

In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why: They work.
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person would not
survive. But most crashes are in between. In many of
them, people who buckle up can survive and sometimes
walk away. Without belts they could have been badly
hurt or killed.
After more than 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up
does matter...a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Take the simplest vehicle. Suppose it is just a seat
on wheels.
1-12

Put someone on it. Get it up to speed. Then stop the vehicle. The rider
does not stop.
1-13

The person keeps going until stopped by something.
In a real vehicle, it could be the windshield...
or the instrument panel...
