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 speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c 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

You may still wish to further adjust the overall ®rmness
or softness of the seat cushion. To get to your
desired level of comfort, hold the control up to increase
the ®rmness, or down for less ®rmness. When you
let go of the control, the seat will automatically readjust
to your desired level of comfort.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support. The lumbar will then automatically
adjust to your body's positioning for the duration of the
trip in two to four-minute cycles.
If you exit the vehicle after the system has been
activated and the seat is left unoccupied for more than
two minutes, the system will de¯ate. You will then
need to readjust the lumbar support upon returning to
your vehicle.
To turn off the adaptive seat feature, brie¯y press the
bottom of the control. The seat will de¯ate when
the adaptive seat control or the ignition is turned off.
If your vehicle has this feature, massaging lumbar is not
available for your vehicle.Heated Seats
Your vehicle may have heated front and rear seats.
The buttons are located on the 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.
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.

Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-45.
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!
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.

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.
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 ®nd 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 1-28.
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.

1. 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.
2. Push the latch plate into the buckle until it clicks.
The latch plates for the safety belts in each rear
seating position vary in size. If the center rear or the
left rear latch plate is inserted into the incorrect
buckle, the plate will not latch properly. Be sure you
are using the correct buckle and that the latch
plate clicks when inserted into the buckle.

There is an air bag readiness light on the instrument
panel, which shows the words AIR BAG or an air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See
Air Bag Readiness Light on page 3-45for more information.
Where Are the Air Bags?
The driver's frontal air bag is in the middle of the
steering wheel. United States

Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you've had a crash, do you need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.

Your vehicle may be equipped with a trunk-lid tie down.
This feature is used to secure the trunk lid if it will
not close completely, such as when carrying large
packages in the trunk. Use the following steps to secure
the trunk lid:
1. Attach the clip end of the tie down to the D ring on
the trunk lid (A).
2. Attach the hook end of the tie down to the striker
located at the center of the trunk sill (B).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end release
and loosen the cord.
Emergency Trunk Release Handle
Notice:The emergency trunk release handle is not
designed to be used to tie down the trunk lid or
as an anchor point when securing items in the trunk.
Improper use of the emergency trunk release
handle could damage it.
There is a glow-in-the-dark emergency trunk release
handle located inside the trunk near the latch. This
handle will glow following exposure to light. Pull the
release handle upward to open the trunk from the inside.

Anti-Pinch Feature
If a hand, an arm or another object is above the middle of
the window and is in the path of the window when the
express-up feature is active, the window will stop at the
obstruction and express-open to a preset factory position.
{CAUTION:
Pressing and holding the power window
control will turn off the anti-pinch feature. If
this happens, a power window won't stop if
something gets in the way. You or others
could be injured, and your window could be
damaged. Be careful not to press and hold the
power window control.
Window Lockout
The rear window lockout
button is located on the
driver's door armrest next
to the window switches.
Pressing this button will disable the rear window
controls. The light on the button will illuminate, indicating
the feature is in use. The rear windows still can be
raised or lowered using the driver's window switches
when the lockout feature is active.
To restore power to the rear windows, press the button
again. The light on the button will go out.
