Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock Release
The trunk lock release
button is located on the left
side of the instrument
panel below the lamp
controls.
Press the trunk lock release button upward to open the
trunk. To use this feature, your vehicle must be in
PARK (P) or NEUTRAL (N) and the valet lockout switch
must be in the OFF position.

Trunk Lid Tie Down
{CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can't see or smell CO. It
can cause unconsciousness and even death. If
you ever need to drive with your trunk lid
open, then:
·Make sure all windows, the rear seat
pass-through and sunroof are closed.
·Turn the fan on your heating and cooling
system to its highest speed, with the
setting on AUTO and temperature between
65ÉF (18ÉC) and 85ÉF (29ÉC). This forces
fresh outside air into your vehicle.
·Open all air ducts on the instrument panel.
Don't use the trunk lid tie down if you are
towing a trailer because of the danger of CO.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.

Ashtrays and Cigarette Lighter
The ashtrays and cigarette lighters may be ordered
through your dealer.
Notice:Don't put papers or other ¯ammable
items into your ashtrays. Hot cigarettes or other
smoking materials could ignite them, causing
a damaging ®re.
Front Ashtray
The front ashtray is located below the climate control
system on the instrument panel.
Press on the lower edge of the cover to access the
ashtray. To clean the ashtray, lift it out by pulling on the
snuffer.
Rear Ashtray
The ashtrays are located on the door armrests. To use
an ashtray, lift the lid.
Cigarette Lighter
Notice:Don't hold a cigarette lighter in with your
hand while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
The front cigarette lighter is located on the center
console in the passenger's side footwell. Open the ¯ip
out door to access the cigarette lighter. Your vehicle
may also have a lighter on the back of the center
console near the rear seat air outlet.
Press the lighter all the way in and release it. It will
pop back out by itself once the element has heated
for use.
Cigarette lighters can be used to provide electrical
power to accessories. See
Accessory Power Outlets on
page 3-26for more information.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode and
the fan speed. AUTO will appear on the display.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70ÉF (21ÉC) and 80ÉF (27ÉC).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the ¯oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see ªSensorsº later in
this section.

Engine Coolant Temperature
Warning Light
This light tells you that
your engine has
overheated. As a check,
the light should come
on for a few seconds when
you start your engine.
If this light comes on and stays on, you should
stop your vehicle and turn the engine off as soon as
possible. A warning chime should also sound if this light
comes on.
See
Engine Overheating on page 5-28.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the shaded area, the engine
is too hot.
That reading means the same thing as the warning
light ± the engine coolant has overheated. See
Engine
Overheating on page 5-28.

Driving on Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On long uphill grades, reduce speed to 45 to 50 mph
(70 to 90 km/h) and avoid prolonged use of SECOND (2)
gear and engine speeds above 3800 rpm.
Climbing grades steeper than four percent at
temperatures above 90É F (32É C) with a loaded vehicle
and trailer is not recommended. The cooling system
may temporarily overheat. See
Engine Overheating on
page 5-28.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks behind the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) ®rmly and apply your parking brake.
5. Release the regular brakes.
4-41

When You Are Ready to Leave After
Parking on a Hill:
1. Apply your regular brakes and hold the pedal down
while you:
·start your engine,
·shift into a gear, and
·make sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle ¯uid (don't over®ll),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you ®nd them quickly. If you're trailering,
it's a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-28.
