Front Heated SeatsÐIf Equipped
Heated seats provide comfort and warmth on cold days
and can help soothe sore muscles and backs. The heaters
provide the same heat level for both cushion and back.
The front driver and passenger seats are heated. The
controls for each heater are located near the bottomcenter of the instrument panel. After turning on the
ignition, you can choose from High, Low, or Off heat
settings. Amber LEDs on the side of each switch indicate
the level of heat in use. Two LEDs are illuminated for
high, one for low, and none for off. Pressing the switch
once will select high-level heating.

Pressing the switch a second time will select low-level
heating. Pressing the switch a third time will shut the
heating elements off.
When high-temperature heating is selected, the heaters
provide a boosted heat level during the first four minutes
of operation after heating is activated. The heat output
then drops to the normal high-temperature level. If
high-level heating is selected, the system will automati-
cally switch to the low level after 30 minutes of continu-
ous operation. At that time, the number of illuminated
LEDs changes from two to one, indicating the change.
Operation on the low setting also turns off automatically
after 30 minutes.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.WARNING!
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat.

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to ªtime-outº (or quit) after several seconds of
transmission ± which may not be long enough for
HomeLinktto pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to ªtime-outº in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace ªProgramming
HomeLinkº Step 3 with the following:
3. Continue to press and hold the HomeLinktbutton
while you press and release - every two seconds
(ªcycleº) your hand-held transmitter until HomeLinkthas successfully accepted the frequency signal. The
EVIC display will change from ªCHANNEL # TRAIN-
INGº to ªCHANNEL # TRAINED.º
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under ªProgramming
HomeLink.º earlier in this section.
Using HomeLinkT
To operate, simply press and release the programmed
HomeLinktbutton. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc. The hand-held transmitter of the device may also be
used at any time.

CLIMATE CONTROLS
Manual Air Conditioning and Heating System Ð If
Equipped
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.
The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow, and they can be adjusted to direct
airflow where the occupant desires.
Manual Air Conditioning and Heating Controls

NOTE:The numbers on the temperature dial represent
a comfort setting when the Mode knob is set to Auto, and
not the actual air temperature.
Operation of the system is quite simple. Begin by turning
the right mode knob to AUTO, and place the blower
control (left knob) to either LO AUTO or HI AUTO. The
LO AUTO position should be used for front seat occu-
pants only. The HI AUTO position should be used when
more air flow is desired, or when rear seat occupants are
present. Dial in the comfort setting you would like the
system to maintain by rotating the driver's or passenger's
control knob. Once the comfort level is selected the
system will maintain that level automatically using the
heating system. Should the desired comfort level require
air conditioning, the system will automatically make the
adjustment.You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. How-
ever, if the driver and/or passenger temperature knobs
are set to the full hot or full cold positions, the air
temperature out of the ducts will be full hot or full cold
respectively. With the temperature setting in these posi-
tions, the system does not attempt automatic comfort
control.
The air conditioning in this system is automatic.
Pressing this button while in AUTO mode will
cause the LED to flash three times and remain off.
This indicates that the system is in AUTO and requesting
the air conditioning is not necessary.

Rear Climate Control Ð If Equipped
The Manual Rear Climate Control system has one floor
air outlet (passenger side), and two panel outlets in the
rear quarter trim (on each side). The unit provides warm
or cool air through the floor and upper outlets.
If rear heating/cooling is desired, press the ªRear On/Off
Switchº (located in the upper switch bank above the
controls) and select ªFloorº ªBi-Levelº or ªPanelº from
the Rear Control Panel (right knob located on the right
rear quarter trim panel).

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift intoN (Neutral) and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.WARNING!
²Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don't leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
²Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
²Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the gear selection lever. Ac-
cidents can also be caused by pressing the accel-
erator pedal. This may cause excessive heat in the
exhaust system, resulting in overheating and ve-
hicle fire, which may cause serious or fatal
injuries.

OVER TEMPº message may display and the transmis-
sion may downshift out of Overdrive until the transmis-
sion cools down. After cool down, the transmission will
resume normal operation.
In high ambient temperatures with sustained high engine
speed and load, an upshift followed shortly thereafter by
a downshift may occur. This is a normal part of the
overheat protection strategy when operating in the
ªTow/Haulº mode.
The transmission will downshift from Overdrive to the
most desirable gear if the accelerator pedal is fully
depressed at vehicle speeds above approximately 35 mph
(56 km/h).
When To Use ªTOW/HAULº Mode Ð If Equipped
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº switch. This will improve
performance and reduce the potential for transmissionoverheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, the transmission will
shift to direct gear and Overdrive will be enabled under
steady cruise conditions.
The ªTOW/HAULº light will illuminate in the instru-
ment cluster to indicate when the switch has beenTOW/HAUL Switch
