BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs must
be marked with an authorized “D.O.T.” for North America and an “E” for
Europe to ensure lamp performance, light brightness and pattern and safe
visibility. The correct bulbs will not damage the lamp assembly or void the
lamp assembly warranty and will provide quality bulb burn time.

diodes (LED). If one or more LEDs burn out, the complete lamp module
has to be replaced. See your authorized dealer for the replacement LED
module.

HOMELINKWIRELESS CONTROL SYSTEM (IF EQUIPPED)
The HomeLinkWireless Control
System, 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
transmitters to operate garage
doors, entry gate operators, security systems, entry door locks, and
home or office lighting.
When programming your HomeLinkWireless Control System 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 HomeLinkWireless Control System 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
HomeLinkat: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 Homelinkbuttons be erased for security purposes, refer to
Programmingin this section.
