Trunk
To open the trunk from the outside, use the key or
press the trunk release button on the remote keyless
entry transmitter.
When closing the trunk, close from the center of the lid
to ensure it fully latches.{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle. If your vehicle has
the remote start feature, the climate control system will
function as part of the remote start feature. The
system will return to the last settings the vehicle was at
when it was turned off.
Operation

(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air-conditioning
compressor.To change the air delivery settings, turn the right knob
to select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Some air may be directed toward the
side windows.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the side
window outlets.
:(Outside Air):Press the right side of this button to
turn the outside air mode on. When this mode is selected,
air from outside the vehicle will circulate throughout your
vehicle. When the button is pressed, an indicator light will
come on to let you know that it is activated. The outside
air mode can be used with all modes, but it cannot be
used with the recirculation mode. Pressing this button will
cancel the recirculation mode.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
defogger on or off. An indicator light will come on
to let you know that the rear window defogger is
activated. Be sure to clear as much snow from the rear
window as possible.
If driving below 50 mph (80 km/h), the rear window
defogger will turn off about 15 minutes after the button
is pressed. If turned on again, the defogger will only
run for about seven minutes before turning off. The
defogger can also be turned off by pressing the button
again or by turning off the engine.
If your vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger will remain on once
the button is pressed.
If your vehicle has the remote start feature, the rear
defogger will automatically be turned on if it is cold
outside. The indicator light will be on. When the vehicle
transitions out of the remote start mode, the rear
defogger will turn off.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Automatic Climate Control System
If your vehicle has this system, you can automatically
control the heating, cooling and ventilation in your
vehicle.
Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed control and the air delivery mode control knobs to
activate the automatic system. When automatic
operation is active the system will control the inside
temperature and air delivery.

Use the steps below to place the entire system in
automatic mode:
1. Place the fan knob and the mode knob to AUTO.
The display will now show the current set
temperature. When auto is selected, the air
conditioning operation and air inlet will be
automatically controlled. The air conditioning
compressor will run when the outside temperature
is over about 40°F (4°C). The air inlet will normally
be set to outside air. If it’s hot outside, the air
inlet may automatically switch to recirculate inside
air to help quickly cool down your vehicle.
2. Set the temperature.
To nd your comfort setting, start with an initial
temperature setting and allow about 20 minutes for
the system to regulate. Press the up or down
arrow temperature buttons to adjust the temperature
setting as necessary. If you choose the temperature
setting of 60°F (15°C) the system will remain at
the maximum cooling setting. If you choosethe temperature setting of 90°F (32°C) the system
will remain at the maximum heat setting. Choosing
either maximum setting will not cause the vehicle
to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps.
Also be careful not to cover the sensor grille on the
lower right side of the climate control faceplate.
This senses the inside vehicle temperature needed
for proper regulation.
To avoid blowing cold air at start-up in cold weather,
the system will delay turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the
fan knob will override this delay and change the fan
to a selected speed.

Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in at or rolling terrain.If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all uid
levels and also the brakes, tires, cooling system,
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.

Three important considerations have to do with weight:
the weight of the trailer
the weight of the trailer tongue
and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (453 kg). But
even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this
section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.When towing a trailer on long uphill grades and the
outside temperature is above 85°F (29°C), reduce your
vehicle speed to 45 mph (72 km/h) to avoid overheating
the engine cooling system.

information or advice, or you can write us at:

Driving On Grades
When towing a trailer on long uphill grades and the
outside temperature is above 85°F (29°C), reduce your
vehicle speed to 45 mph (72 km/h) to avoid overheating
the engine cooling system.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
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 is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transaxle 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 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 shift into PARK (P).
5. Release the regular brakes.
