WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.
Service engine soon
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine’s emission control
systems may be malfunctioning. The light may illuminate without a
driveability concern being noted. The vehicle will usually be drivable and
will not require towing.
Light remains on:
Temporary malfunctions may cause the light to illuminate. Examples are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light
should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.

HOMELINKUNIVERSAL TRANSCEIVER (IF EQUIPPED)
The HomeLinkUniversal Transceiver, located on the driver’s visor,
provides a convenient way to replace up to three hand-held transmitters
with a single built-in device. This feature will learn the radio frequency
codes of most current transmitters to operate garage doors, entry gate
operators, security systems, entry door locks, and home or office lighting.
When programming your HomeLinkUniversal Transceiver to a
garage door or gate, be sure that people and objects are out of
the way to prevent potential harm or damage.
Do not use the HomeLinkUniversal Transceiver with any garage door
opener that lacks safety stop and reverse features as required by U.S.
federal safety standards (this includes any garage door opener model
manufactured before April 1, 1982). A garage door which cannot detect
an object, signaling the door to stop and reverse, does not meet current
U.S. federal safety standards. For more information, contact HomeLink
at:www.homelink.comor1–800–355–3515.

Retain the original transmitter for use in other vehicles as well as for
future programming procedures (i.e. new HomeLinkequipped vehicle
purchase). It is also suggested that upon the sale of the vehicle, the
programmed HomelinkUniversal Transceiver buttons be erased for
security purposes, refer toProgrammingin this section.
Programming
Do not program the HomeLinkUniversal Transceiver with the
vehicle parked in the garage.
Note:Your vehicle may require the ignition switch to be turned to the
ACC position for programming and/or operation of the HomeLink.Itis
also recommended that a new battery be placed in the hand-held
transmitter of the device being programmed to HomeLinkfor quicker
training and accurate transmission of the radio-frequency signal.
1. Press and hold the two outside
buttons releasing only when the red
light begins to flash after 20
seconds.Do notrepeat step one to
program additional hand-held
transmitters to the remaining two
HomeLinkbuttons. This will erase
previously programmed hand-held
transmitter signals into HomeLink.
2. Position the end of your
hand-held transmitter 2–8cm(1–3 inches) away from the HomeLink
Universal Transceiver surface (located on your visor) while keeping the
red light in view.
3. Simultaneously press and hold
both the HomeLinkand 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 replace
step 3 with procedures noted in the
“Gate Operator and Canadian Programming”section for Canadian
residents.
4. The red light will flash slowly and then rapidly. Release both buttons
when the red light flashes rapidly. (The rapid flashing light indicates
acceptance of the hand-held transmitters’radio frequency signals.)

•Continue to press and hold the HomeLinkbutton (note step 3 in the
“Programming”section) while you press and release—every two
seconds(“cycle”) your hand-held transmitter until the frequency
signal has been accepted by the HomeLink. The red indicator light
will flash slowly and then rapidly after HomeLinkaccepts the radio
frequency signal.
•Proceed with step 4 in the“Programming”section.
Operating the HomeLinkUniversal Transceiver
To operate, simply press and release
the appropriate HomeLinkbutton.
Activation will now occur for the
trained product (garage door, gate
operator, security system, entry
door lock, or home or office lighting
etc.). For convenience, the
hand-held transmitter of the device
may also be used at any time. In the event that there are still
programming difficulties, contact Homelinkatwww.homelink.comor
1–800–355–3515.
Erasing HomeLinkbuttons
To erase the three programmed
buttons (individual buttons cannot
be erased):
•Press and hold the two outer
HomeLinkbuttons until the red
indicator light begins to
flash-after 20 seconds. Release
both buttons. Do not hold for
longer that 30 seconds.
HomeLinkis now in the train (or
learning) mode and can be programmed at any time beginning with step
2inthe“Programming”section.
Reprogramming a single HomeLinkbutton
To program a device to HomeLinkusing a HomeLinkbutton previously
trained, follow these steps:
1. Press and hold the desired HomeLinkbutton.Do NOTrelease the
