Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
Engine Exhaust on page 2-37.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-28.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake after you move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-33.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-41.

Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
internet at: www.homelink.com or by calling
1-800-355-3515.Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.

Exterior Lamps
The exterior lamp control
is located to the left of the
steering wheel on the
instrument panel.
O(Exterior Lamp Control):Turn the control with
this symbol on it to operate the exterior lamps.The exterior lamp control has three positions:
9(Off):Turn the control to this position to turn off all
lamps except the Daytime Running Lamps (DRL).
;(Parking Lamp):Turn the control to this position
to turn on the parking lamps together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
The parking brake indicator light will come on and stay

3-17

Reading Lamps
The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than
normal to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the fan may cut back to a
lower speed. For more battery saving information, see
“Battery Saver Active Message” underDIC Warnings
and Messages on page 3-65.

yPASS TEMPz(Passenger’s Temperature):
Press this switch to turn the passengers’ climate control
systems on. Press this switch to manually increase
or decrease the temperature for the front passenger.
PASS OFF (Passenger’s Climate Control):Press this
button to turn all passenger climate control systems off.
If the passenger’s temperature switch is turned off, the
driver’s temperature knob will control the temperature for
the entire vehicle.
A/C (Air Conditioning):Press this button to override
the automatic system and turn the air-conditioning
system on or off. When in AUTO the air-conditioning
compressor will come on automatically, as necessary.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Open all outlets.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, after the air in your
vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
If your vehicle has the memory option, it can be used to
recall your climate control settings. For more information,
seeClimate Controls Personalization on page 3-43.

1FRONT (Defrost):Pressing FRONT directs most of
the air to the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode, the
system will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Do not drive the
vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
The rear window defogger will turn off approximately 10
minutes after the button is pressed. If turned on
again, the defogger will only run for approximately ve
minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
REAR button is pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the levers located in the center of each outlet to
change the direction of the airow. Use the thumbwheels
to open or close the outlets.

y9z(Fan):Pressing this switch cancels automatic
operation and places the system in manual mode.
Press this switch to increase or decrease the fan speed.
Press the MODE switch until AUTO is displayed to
return to automatic operation.
yTEMPz(Temperature):Press this switch to
increase or decrease the temperature for the rear seat
passengers.
For cool air to be sent to the rear of the vehicle, the
air-conditioning system on the main climate-control
panel must be on. If it is not on, then the temperature in
the rear of the vehicle will remain at cabin temperature.
Be sure to keep the area under the front seats clear
of any objects so that the air inside of your vehicle can
circulate effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it may need to
be changed periodically. For how often to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
