to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out 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.
1. Turn the ignition switch to the ON/RUN position.
2. Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLinkbutton you wish to program
while keeping the HomeLink indicator light in view.
3. Continue to press and hold the HomeLink button,
while you press and release (“cycle”), your hand-held
transmitter every two seconds until HomeLink has
successfully accepted the frequency signal. The indicator
light will flash slowly and then rapidly when fully
trained. 4. Watch for the HomeLink
indicator to change flash
rates. When it changes, it is programmed. It may take up
to 30 seconds or longer in rare cases. The garage door
may open and close while you are programming.
5. Press and hold the programmed HomeLink button
and observe the indicator light.
•If the indicator light stays on constantly, program-
ming is complete and the garage door/device
should activate when the HomeLink button is
pressed.
•To program the two remaining HomeLink buttons,
repeat each step for each remaining button. DO
NOT erase the channels.
If you unplugged the garage door opener/device for
programming, plug it back in at this time.

21. SERV (Service) 4WD Indicator Light — If EquippedThe “SERV 4WD Indicator Light” will turn on
when the ignition key is turned to the ON/
RUN position and it will stay on for two
seconds. If the light stays on or turns on during
driving, it means that the 4WD system is not functioning
properly and that service is required.
22. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As engine coolant temperatures rise and the
gauge approaches H,this indicator will illuminate
and a single chime will sound after reaching a set
threshold. Further overheating will cause the tempera-
ture gauge to pass H,the indicator will continuously
flash and a continuous chime will occur until the engine
is allowed to cool. If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
23. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pressing the Recirculation button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pressed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation Mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode knob to Panel, Panel/Floor and then
press the Recirculation button. This feature reduces the
possibility of window fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation Mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fourth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
•the shift lever is in the DRIVE position,
•the transmission fluid has reached an adequate tem-
perature,
•the engine coolant has reached an adequate tempera-
ture,
•vehicle speed is sufficiently high,
•the driver is not heavily pressing the accelerator, and
•the TOW/HAUL button has not been activated.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to select TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, the transmission will downshift into third gear.

STARTING AND OPERATING 331

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
switch bank below the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating your engine by taking the
appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately and call for service.
434 WHAT TO DO IN EMERGENCIES

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the
wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.NOTE:
If your vehicle is equipped with Traction Con-
trol or Electronic Stability Control (ESC), turn the system
OFF before attempting to “rock” the vehicle.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
448 WHAT TO DO IN EMERGENCIES

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately. To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
