Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
Vacation/Storage
Before 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 fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your cabin
air filter, and to have it replaced when needed.

Before You Begin Programming HomeLink
Ensure your vehicle is parked outside of the garage before
you begin programming.
For efficient programming and accurate transmission of
the radio-frequency signal it is recommended that a new
battery be placed in the hand-held transmitter of the device
that is being programmed to the HomeLink system.
To erase the channels place the ignition in the ON/RUN
position and push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds. The instrument
cluster display will display “CLEARING CHANNELS.”
Release the buttons when “CHANNELS CLEARED” ap-
pears on the display.
NOTE:
•For vehicle’s equipped with Keyless Enter-N-Go, place
the ignition in the RUN position with the Engine ON.
Make sure while programming HomeLink with the
engine ON that your vehicle is outside of your garage, or
that the garage door remains open at all times. •
Erasing all channels should only be performed when
programming HomeLink for the first time. Do not erase
channels when programming additional buttons.
• If you have any problems, or require assistance, please
call toll-free 1-800-355-3515 or, on the Internet at
HomeLink.com for information or assistance.
Programming A Rolling Code
For programming garage door openers that were manufac-
tured after 1995. These garage door openers can be identi-
fied by the “LEARN” or “TRAIN” button located where
the hanging antenna is attached to the garage door opener.
It is NOT the button that is normally used to open and
close the door. The name and color of the button may vary
by manufacturer.

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 signals
to time-out (or quit) after several seconds of transmission –
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. Turn the ignition switch to the ON/RUN position.
NOTE:
For vehicle’s equipped with Keyless Enter-N-Go,
place the ignition in the RUN position with the Engine ON.
For vehicle’s equipped with Keyless Enter-N-Go, place the

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.
(Continued)
CAUTION! (Continued)
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.
Cigar Lighter And Ash Receiver — If Equipped
A removable cigar lighter and ash receiver are available.
For vehicles with a bench seat, the cup holder tray can be
used to hold the ash receiver.
Power Inverter — If Equipped
A 115 or 230 Volt (150 Watts Maximum) outlet is located on
the center stack of the instrument panel, to the right of the
radio. This outlet can power cellular phones, electronics and
other low power devices requiring power up to 150 Watts.
Certain high-end video game consoles will exceed this power
limit, as will most power tools.
The power inverter is designed with built-in overload
protection. If the power rating of 150 Watts is exceeded, the
power inverter will automatically shut down. Once the
electrical device has been removed from the outlet the
inverter should automatically reset.

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Instrument Cluster Display •When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily. •
The gauge pointer will likely indicate a higher tem-
perature 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.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age 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,” turn the engine off immediately and call an
authorized dealer for service.
