Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter (if equipped).
When closing the trunk, close from the center to ensure
it fully latches. Although you may use one hand to
unlock the trunk, it is recommended that two hands on
the upper surface be used to close the 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 with the setting
on any airflow selection except maximum.
That will force outside air into your vehicle.
See ªComfort Controlsº 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.

Ashtrays and Cigarette Lighter
(If Equipped)
To use the lighter, just push it in all the way and let go.
When it's ready, it will pop back out by itself.
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.
To clean the center console ashtray, remove the entire
ashtray and empty it. The ashtray can be placed in the
rear cupholder for the rear seat passengers to use.
NOTICE:
Don't put papers and other things that burn into
your ashtrays. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
Sun Visors
To block out glare, you can swing down the visors.
You can also swing them to the side.

2-66 Enhanced Traction System Active Light
United States Canada
When your Enhanced Traction System is limiting wheel
spin, this light will come on. Slippery road conditions
may exist if the Enhanced Traction System active light
comes on, so adjust your driving accordingly.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
there to tell you when the system is active.
Engine Coolant Temperature Gage
United States Canada
Your vehicle is equipped with one of these gages.
With the ignition in RUN, this gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot! It means that your engine coolant has
overheated. The CHECK GAGES light should come on
if this condition exists. See ªCheck Gages Lightº later in
this section for more information. If you have been
operating your vehicle under normal conditions, you
should pull off the road, stop your vehicle and turn off
the engine as soon as possible.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.

2-67 Low Coolant Warning Light
This light comes on
briefly when you turn
your ignition on.
If this light comes on and stays on, the coolant level in
your vehicle is low. If the light is on along with an
overheat warning, you may have a serious overheating
problem. See ªEngine Coolant Temperature Gageº in
the Index.
NOTICE:
Damage to your engine from neglected coolant
problems can be costly and is not covered by
your warranty.
See ªEngine Coolantº in the Index for information
on what to do. Your vehicle should be serviced as soon
as possible.
Malfunction Indicator Lamp
(Check Engine Light)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.

Comfort Controls
This section tells you how to make your air system
work for you. With these systems, you can control the
ventilation and heating in your vehicle. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Climate Control System
Fan Knob
The left knob selects the force of air you want.
Turn the knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the
fan off, turn the mode knob all the way counterclockwise
to OFF. In any other setting, the fan will run continuously
with the ignition on. The fan must be on to run the air
conditioning compressor.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward
red (clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, set the
temperature to a comfortable setting.

3-4 Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
For quick cool
-down on very hot days, use the
maximum mode setting with the temperature knob
all the way in the blue area. If this setting is used for
long periods of time, the air in your vehicle may become
too dry. The best cool
-down happens if you start in
one of the other modes and then switch to maximum.
For normal cooling on hot days, use vent with the
temperature knob in the blue area and the A/C button
pressed in. The system will bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level with the temperature knob in the
middle and the A/C button pressed in. The system will
bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use defrost with the temperature knob all the way
in the red area. To warm passengers while keeping the
windows clean, use defog.

3-6 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use vent to direct outside air through
your vehicle. Your vehicle also has the flow
-through
ventilation system.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to floor and the fan to the highest speed
for a few moments before driving off. This helps
clear the intake ducts of snow and moisture and
reduces the chance of fogging the inside of
your windows.

Keep the air path under the front seats clear
of objects. This helps air circulate throughout
your vehicle.

4-41 Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before you 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 a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to reduce
engine load. See ªEngine Overheatingº in the Index.
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 don't shift into
PARK (P) yet or into gear for a manual transaxle.
When parking uphill, turn your wheels away from
the curb. When parking downhill, turn your wheels
into the curb.
2. Have someone place chocks under 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 apply your parking
brake, and then shift to PARK (P).
5. Release the regular brakes.

4-42 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

release the parking brake.
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 fluid (don't overfill),
engine oil, drive belt, cooling system and brake system.Each of these is covered in this manual, and the Index
will help you find 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. See ªEngine Overheatingº
in the Index.
Towing a Trailer
(Models with 2.2L L4 (LN2) Engine
or Manual Transaxle)
Do not tow a trailer if your vehicle is:

equipped with a 2.2L L4 (LN2) engine or

equipped with a manual transaxle.
