The HomeLinktWireless Control System provides a
convenient way to replace up to three hand-held radio-
frequency (RF) transmitters used to activate devices such
as gate operators, garage door openers, entry door locks,
security systems, even home lighting. Additional
HomeLink information can be found at:
www.homelink.comor by calling1-800-355-3515.

WARNING!
Before programming HomeLink to a garage door
opener or gate operator, make sure that people and
objects are out of the way of the device to prevent
potential harm or damage. When programming a
garage door opener, it is advised to park outside of
the garage. Do not use HomeLink with any garage
door opener that lacks safety stop and reverse fea-
tures as required by U.S. federal safety standards
(this includes any garage door opener model manu-
factured before April 1, 1982). A garage door that
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.com or by calling:
1-800-355-3515.
Retain the original transmitter of the RF device you are
programming for use in other vehicles as well as for
future HomeLink programming. It is also suggested that
upon the sale of the vehicle, the programmed HomeLink
buttons be erased for security purposes. To erase the
programmed buttons, perform the procedure shown
below under9When Your Vehicle Is New9, or, for assis-
tance, contact HomeLink at:www.homelink.comor by
calling:1-800-355-3515.
When Your Vehicle Is New
Prior to programming HomeLink for the first time the
factory test codes must be erased. To erase HomeLink
memory, press and hold the two outer HomeLink buttons
(buttons one and three). The message CLEARING
CHANNELS will appear on the HomeLink display. After
approximately 20 seconds, the message CHANNELS
CLEARED will appear on the EVIC display. Do not hold
the buttons for longer than 30 seconds.

Programming HomeLink
NOTE:It is recommended that a new battery be placed
in the hand-held transmitter of the device being pro-
grammed to HomeLink for quicker training and accurate
transmission of the radio frequency signal.
WARNING!
Vehicle exhaust contains carbon monoxide, a danger-
ous gas. Do not run the vehicle's engine while
programming HomeLink. Exhaust gas can cause se-
rious injury or death.
WARNING!
Your motorized door or gate will open and close
while you are programming HomeLink. Do not
program HomeLink if people or pets are in the path
of the door or gate. A moving door or gate can cause
serious injury or death to people and pets or damage
to objects.
1. Position the end of your hand-held transmitter 1-3
inches (5-14 cm) away from the lower left corner of the
EVIC display while keeping the display in view.
NOTE:Some gate operators and garage door openers
may require you to replace the next step with procedures
noted in the9Gate Operator/Canadian Programming9
section.
2. Simultaneously press and hold both the desired
HomeLink button and the hand-held transmitter button.
108 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

After a short time, the message TRAINING will show on
HomeLink display.Do not release the buttons until the
next step has been completed.
3. When the message TRAINED appears on the
HomeLink display, release both the HomeLink and hand-
held transmitter buttons.NOTE:If the HomeLink display does not change to
TRAINED, contact HomeLink atwww.homelink.comor
call1-800-355-3515for assistance.
4. Press and hold the just-trained HomeLink button.
TRANSMIT should appear on the display.
If your device activates when the HomeLink button is
depressed and released, programming is complete.
NOTE:To program the remaining two HomeLink but-
tons, simply repeat the9Programming HomeLink9pro-
cess.
If the message TRANSMIT appears on the HomeLink
display but your device does not activate, the device may
be equipped with a9rolling code9system. Continue with
steps five through seven below to complete the program-
ming of a rolling code equipped device (most commonly
a garage door opener).

Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to9time-out9(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 to9time-out9in the same manner.
If you live in Canada or you are having difficulties
programming a gate operator by using the9Program-
ming HomeLink9procedures (regardless of where you
live), replace step two with the following:
NOTE:If programming a garage door opener or gate
operator, it is advised to unplug the device during the
9cycling9process to prevent possible overheating.
Press and hold the HomeLink button while you press
and release - every two seconds ((cycle() your hand-heldtransmitter button until the radio signal has success-
fully been accepted by HomeLink. (The message
TRAINED will appear on the HomeLink display.)
Proceed with the remaining steps under9Programming
HomeLink9to complete.
Using HomeLink
To operate, simply press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e. garage door opener, gate operator,
security system, entry door lock, home/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 or questions,
contact HomeLink at:www.homelink.comor1-800-355-
3515.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gage reads high, 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 in
the high range, turn the engine off immediately, and
call for service.
15. Reset Button
Press this button to toggle between the odometer and trip
odometer display. When in the trip odometer mode,
holding the button in resets the trip odometer.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. There are six digits including leading zeros.
The odometer is tamper-resistant.U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer records distance in miles from when-
ever the ªResetº button is pushed. To switch from the
odometer being displayed to the trip odometer being
displayed, press the ªResetº button.
17. O/D (Overdrive) Off Indicator Light
This light will illuminate when the O/D OFF
button has been selected. The O/D OFF button is
located on the gear shift lever.

ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
Clock Setting Procedure
1. Turn the ignition switch to the ON or ACC position
and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
