CAUTION
Use the headlights with the engine run-
ning to avoid discharging the vehicle
battery.
Autolight system
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:∙ Turn on the headlights, front parking, tail, license plate and instrument panel
lights automatically when it is dark.
∙ Turn off all the lights when it is light.
∙ Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed. NOTE:
Autolight activation sensitivity and the
time delay for autolight shutoff can be
adjusted. For additional information, re-
fer to “Vehicle information display ” in
this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF (if so equipped),
,
or
position.

Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.

proximately 25 mph (40 km/h) and above. If
an oncoming vehicle or leading vehicle ap-
pears in front of your vehicle when the
headlight high beam is on, the headlight
will be switched to the low beam automati-
cally.
WARNING
∙ The High Beam Assist system is a con- venience but it is not a substitute for
safe driving operation. The driver
should remain alert at all times, en-
sure safe driving practices and switch
the high beams and low beam manu-
ally when necessary.
∙ The high beam or low beam may not switch automatically under the fol-
lowing conditions. Switch the high
beam and low beam manually.
– During bad weather (rain, fog, snow, wind, etc.).
– When a light source similar to a headlight or tail light is in the vicin-
ity of the vehicle.

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 de- vices 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
vehicle’s battery is discharged or is dis-
connected, HomeLink® will retain all
programming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, refer to “Programming
HomeLink®” in this section.

WARNING
∙ Your vehicle’s engine should beturned off while programming the
HomeLink® Universal Transceiver. For
additional information, refer to
“Push-button ignition switch” in the
“Starting and driving” section of this
manual. Do not breathe exhaust
gases; they contain colorless and
odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause
unconsciousness or death.
∙ Do not use the HomeLink® Universal Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent 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
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice being programmed to HomeLink®
for quicker programming and accurate
transmission of the radio frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
1in view.
