Autolamp delay system (if equipped)
If your vehicle is equipped with autolamps, you can set the delay time to
keep the headlights on for up to three minutes after the key is turned
off. The delay time is set to 20 seconds at the factory, but the delay time
may be changed by following the steps below (Steps 1 through 6 must
be done within 10 seconds):
1. Turn the key to the off position.
2. Rotate the headlamp control to
the autolamp position.
3. Rotate the headlamp control to
the off position.
4. Turn the key to the on position.
5. Turn the key back to the off
position.
6. Turn the headlamp control to the
autolamp position (the headlights should turn on).
7. Turn the headlamp control to the off position when the desired delay
time (up to 3 minutes) has been reached.
Fog lamp control
The headlamp control also operates
the fog lamps. The fog lamps can be
turned on when the headlamp
control is in the
or
positions and the high beams are
not turned on.
Pull the headlamp control towards
you to turn the fog lamps on. The
fog lamp indicator light
will
illuminate.

Interior lighting battery saver
The interior lamps will automatically extinguish after 10 minutes when
the ignition key is in the off/lock position, a door has been left open or
the interior lamp controls are in the on position.
BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to dealer for service if any of the above conditions of
unacceptable moisture are present.

KEYS
Your vehicle is equipped with two
Integrated Keyhead Transmitters
(IKTs). The key blade functions as a
programmed key which starts the
vehicle and unlocks/locks all the
doors. The transmitter portion
functions as the remote entry
transmitter.
Your IKTs are programmed to your vehicle; using a non-programmed key
will not permit your vehicle to start. If you lose your authorized dealer
supplied IKTs, replacement IKTs are available through your authorized
dealer. Standard SecuriLock™ keys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired.
Always carry a spare key with you in case of an emergency.
For more information regarding programming replacement IKTs, refer to
theSecuriLock™ passive anti-theft systemsection later in this chapter.
Note:Your vehicle’s IKTs were
issued with a security label that
provides important vehicle key cut
information. It is recommended that
you keep the label in a safe place
for future reference.
