Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO),
follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
• If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is
set at high speed. DO NOT use the recirculation
mode.

WARNING! (Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.

Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink®
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. Cycle the ignition to the ON/RUN position.
2.
Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLink® button 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 indi-
cator 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.

release of the switch, the wipers will resume the continu-
ous rear wiper operation. When this rotary control is in
the OFF position, rotating it downward will activate the
rear washer pump which will continue to operate as long
as the switch is held. Once the switch is released it will
return to the OFF position and the wipers will cycle
several times before returning to the parked position.
NOTE:As a protective measure, the pump will stop if the
switch is held for more than 20 seconds. Once the switch
is released the pump will resume normal operation.
If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the “park”
position.
Rear Window Defroster
The rear window defroster button is located on
the climate control panel. Press this button to turn
on the rear window defroster and the heated outside mirrors (if equipped). An indicator in the button will
illuminate when the rear window defroster is on. The
rear window defroster automatically turns off after ap-
proximately 10 minutes. For an additional five minutes of
operation, press the button a second time.
NOTE:
To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.

•Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position. The light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing. •
Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a single
chime will sound after reaching a set threshold. Further
overheating will cause the temperature 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 more information.
