For additional information, see “Exterior and
interior lights” (P. 8-24).The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency devices
such as garage doors, gates, home and
office lighting, entry door locks and security
systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the vehi-
cle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, see “Programming
HomeLink®” (P. 2-74).WARNING
• Your vehicle's engine should be turned
off while programming the HomeLink®
Universal Transceiver. For additional in-
formation, see “Push-button ignition
switch” (P. 5-13). Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door opener
that lacks safety stop and reverse fea-
tures as required by federal safety stan-
dards. (These standards became effec-
tive for opener models manufactured
after April 1, 1982.) A garage door
opener which cannot detect an object in
the path of a closing garage door and
then automatically stop and reverse
does not meet current federal safety
standards. Using a garage door opener
without these features increases the risk
of serious injury or death.
• During the programming procedure your
garage door or security gate will open
and close (if the transmitter is within
range). Make sure that people or objects
are clear of the garage door, gate, etc.,
that you are programming.

PROGRAMMING HOMELINK®
If you have any questions or are having diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call
1-800-355-3515.
NOTE:
Place the ignition switch in the ON position
(without starting the engine) when pro-
gramming HomeLink®. It is also recom-
mended that a new battery be placed in the
hand-held transmitter of the device being
programmed to HomeLink® for quicker pro-
gramming and accurate transmission of the
radio frequency.1. Position the end of your hand-held trans-
mitter 1–3 in (2–8 cm) away from the
HomeLink® surface, keeping the
HomeLink® indicator light
O1in view. 2. Using both hands, simultaneously press
and hold the desired HomeLink® button
and hand-held transmitter button. DO
NOT release until the HomeLink® indica-
tor light
O1flashes slowly and then rap-
idly. When the indicator light flashes rap-
idly, both buttons may be released. (The
rapid flashing indicates successful
programming.)
NOTE:
Some devices may require you to replace
Step 2 with the cycling procedure noted in
“Programming HomeLink® for Canadian
customers and gate openers” (P. 2-75).

OPERATING RANGE
WARNING
• To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.
• Do not use Remote Engine Start in closed
spaces such as a garage. Do not breathe
exhaust gases; they contain colorless
and odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause un-
consciousness or death.
CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating lo-
cation, the Intelligent Key operating range
becomes narrower, and the Intelligent Key
may not function properly.
The Remote Engine Start function can only
be used when the Intelligent Key is within the
specified operating range from the vehicle.
The Remote Engine Start operating range is
approximately 197 ft (60 m) from the vehicle.
REMOTE STARTING THE
VEHICLE

form the following:
1. Aim the Intelligent Key at the vehicle.
2. Press the
button to lock all doors.
3. Within 5 seconds press and hold the

Pre-driving checks and adjustments3-19

The following events will occur when the en-
gine starts:
• The parking lights will turn on and remainon as long as the engine is running.
• The doors will be locked and the climate control system may come on.
• The engine will continue to run for 10 min- utes. Repeat the steps to extend the time
for an additional 10 minutes. For additional
information, see “Extending engine run
time” (P. 3-20).
Press and hold the brake pedal while switch-
ing the ignition to the ON position before
driving. For additional information, see “Driv-
ing the vehicle” (P. 5-18).
EXTENDING ENGINE RUN TIME
The Remote Engine Start feature can be ex-
tended one time by performing the steps
listed in “Remote starting the vehicle”
(P. 3-19). Run time will be calculated as
follows:
• The first 10 minute run time will start when the Remote Engine Start function is
performed. • The second 10 minutes will start immedi-
ately when the Remote Engine Start func-
tion is performed again. For example, if the
engine has been running for 5 minutes, and
10 minutes are added, the engine will run
for a total of 15 minutes.
• Extending engine run time will bring you to the two Remote Engine Start limit.
A maximum of two Remote Engine Starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON
position and then back to the OFF position
before the Remote Engine Start procedure
can be used again.

the engine compartment, to avoid injury
do not open the hood.
• Do not pull the hood lock release handle
or push the hood down after the pop-up
engine hood system activates. Doing so
could cause personal injury or damage to
