You can obtain a French copy of this manual from your
dealer or from:
Helm, Incorporated
P.O. Box 07130
Detroit, MI 48207
How to Use This Manual
Many people read their owner’s manual from beginning
to end when they first receive their new vehicle. If
you do this, it will help you learn about the features and
controls for your vehicle. In this manual, you will find
that pictures and words work together to explain things.
Index
A good place to look for what you need is the Index in
back of the manual. It is an alphabetical list of what
is in the manual, and the page number where you will
find it.
ii

Safety Warnings and Symbols
You will find a number of safety cautions in this book.
We use a box and the word CAUTION to tell you 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 don’t, you
or others could be hurt.
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Don’t,”
“Don’t do this” or “Don’t let
this happen.”
iii

Vehicle Damage Warnings
Also, in this book you will find 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 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
Power Seats
The power seat controls
are located on the
outboard sides of the front
seat cushions.
•Move the front of the seat control up or down to
adjust the front portion of the cushion.
•Move the rear of the seat control up or down to
adjust the rear portion of the cushion.
•Lift up or push down on the center of the seat
control to move the entire seat up or down.
•Slide the seat control forward or rearward to move
the seat forward or rearward.
Power Lumbar
If your vehicle has this
feature, the control is
located on the outboard
sides of the front seats.
Use the power seat controls first to get the proper
position, then continue with the lumbar adjustment.
Press the lumbar control forward to increase support
and rearward to decrease support. Press the control up
or down to raise or lower the support mechanism.
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.
1-2

Massaging Lumbar
If your vehicle has this
feature, the control is
located on the outboard
sides of the front
seats. With the ignition on,
briefly press the top of
the control where it
is marked AUTO to
activate the massaging
lumbar feature.
The massage cycle will run continuously for up to
10 minutes and can be interrupted by briefly pressing the
bottom of the control. The lumbar support can be
adjusted during the massage cycle by moving the control
forward to increase support and rearward to decrease
support. The massage cycle will continue to run even if
the ignition is turned to OFF unless interrupted.
If your vehicle has this feature, it will not have the
adaptive seat feature.
Heated Seats
Your vehicle may have heated rear seats.
The buttons are located on the rear seat armrests.
Press the buttons to turn the feature on. Press them
again to turn off the heated seats. The feature will also
shut off when the ignition is turned to OFF.
1-3

The HEAT/OFF button controls the temperature settings
HI, MED and LO. The other button is to choose BACK
ONLY heating. The LO setting warms the seatback and
cushion until the seat approximates body temperature.
The MED and HI settings heat the seatback and
seat cushion to a slightly higher temperature, and the
BACK ONLY heats only the seatback.
The temperature can be adjusted by pushing the button
from HI to LO or, until the desired setting is reached.
You will be able to feel heat in about two minutes.
To heat just the seatback, push the BACK ONLY button
once, after first activating the heated seat feature. To
resume heat to both the seat cushion and seatback,
press the button again.
Heated and Cooled Seats
Your vehicle may have heated and cooled front seats.
The buttons are located on
the front seat armrests.
I(Heated Seatback): Press this button to turn on the
heated seatback.
J(Heated Seat and Seatback): Press this button to
turn on the heated seat and seatback.
H(Cooled Seat): Press this button to turn on the
cooled seat.
Press the button to turn on the feature that you want. A
light on the button will display to show which feature
is on.
1-4

There are three temperature ranges for each feature.
A light bar on the controls will display which setting the
feature is in; high, medium or low. The longest bar
shows the high range and the shortest bar shows the
low range.
When you press a button, the feature will turn on at the
highest setting. Each time you press the button, the
feature will go down on temperature setting.
To turn the feature off, keep pressing the button until
the display lights turn off.
Reclining Seatbacks
The recliner controls are
located on the outboard
sides of the front seats.
Press the recliner control forward or rearward to adjust
the seatback forward or rearward.
1-5

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 can’t do their job
when you’re reclined like this.
The shoulder belt can’t do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can’t 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.
1-6

Rear Seats
Power Lumbar
Your vehicle may be equipped with four-way lumbar
support, without the massage feature, for the outboard
rear seating positions.
The rear lumbar support
controls are located on the
rear door trim panels.
To activate the rear lumbar support feature, push
forward on the control to increase support or rearward
to decrease support. The lumbar control can also
be moved up and down to adjust the location of the
support.
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.
1-7

{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 3-46.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why: They work.
You never know if you’ll be in a crash. If you do have a
crash, you don’t 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 wouldn’t 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!
1-8

Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it’s just a seat on
wheels.
Put someone on it.
1-9

Get it up to speed. Then stop the vehicle. The rider
doesn’t stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield...
1-10

or the instrument panel... or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.
1-11

Questions and Answers About
Safety Belts
Q: Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A: You could be – whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re upside down. And your chance
of being conscious during and after an accident,
so you can unbuckle and get out, is much greater if
you are belted.
Q: If my vehicle has air bags, why should I have to
wear safety belts?
A: Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they work with
safety belts – not instead of them. Every air bag
system ever offered for sale has required the
use of safety belts. Even if you’re in a vehicle that
has air bags, you still have to buckle up to get
the most protection. That’s true not only in frontal
collisions, but especially in side and other
collisions.
Q: If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A: You may be an excellent driver, but if you’re in an
accident – even one that isn’t your fault – you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, see Older Children on page 1-28
or Infants and Young Children on page 1-30. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
1-12

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 lap–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.
1-13

4. Push the latch plate into the buckle until it clicks.
Be sure to use the correct buckle when buckling
your lap-shoulder belt. If you find that the latch plate
will not go fully into the buckle, see if you are
using the buckle for the center passenger position.
Pull up on the latch plate to make sure it is
secure. If the belt isn’t long enough, see Safety 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.
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you’d be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of
the body are best able to take belt restraining forces.
The safety belt locks if there’s a sudden stop or crash,
or if you pull the safety belt very quickly out of the
retractor.
