Content Theft-Deterrent System

System
• Lock the doors using the power door
lock switch or by pressing the Lock
button on the Remote Keyless Entry
transmitter.
• After closing all doors, the security
light on the instrument panel cluster
stops flashing and remains lit. After a
delay of about 30 seconds, the lamp
darkens and the system arms itself.
• When arming with the power door
lock switch, at least one door must be
open and the key must be removed
from the ignition. (A door does not
have to be open to arm the system
with the Remote Keyless Entry
transmitter.)
• The system will not arm if the door is
locked with a key or the manual door
lock button is pressed.
• If the alarm is tripped, the horn
sounds and the headlamps/taillamps
flash for about two minutes. The
alarm sounds whenever a locked
door is opened without the key or
Remote Keyless Entry transmitter,
or if someone attempts to turn on
the ignition without the correct key.

Unlock on the Remote Keyless Entry

PERFORMANCE & MAINTENANCE
Malfunction Indicator Lamp
(Service Engine Soon Lamp)
This instrument panel cluster lamp
illuminates under a variety of conditions
when the On-Board Diagnostics II (OBD
II) system detects a malfunction in the
vehicle’s emission controls.
If the Malfunction Indicator Lamp
is lit steadily, check the gas cap to
ensure it is present and securely
fastened
• Turn the cap clockwise until a ratch-
eting sound is heard, signaling that it
is secure.
• If this is the cause of the condition, a
few driving trips with the cap installed
properly should turn the light off.
See Section 3 of your Owner Manual.
Electronically Controlled
Air Suspension (if equipped)
Occasional whirring and/or hissing
sound under the rear of the vehicle
• This sound indicates that the sys-
tem’s air compressor is operating to
provide a level ride height, and is
normal.
See Section 4 of your Owner Manual.
Luggage Carrier (if equipped)
Slide the crossrails to desired
position
1. Pull up the lever on each side of the
crossrail. This will release the cross-
rail and allow you to slide it.
2. When the crossrail is where you want
it, press down on the levers to lock it
in place.
Reduce wind noise when the roof
luggage carrier is not in use
• Position the rear crossrail at the
rearmost position and the front
crossrail above the rearmost portion
of the rear door opening (above the
C-pillar).
See Section 2 of your Owner Manual.
Note:Never carry anything on the vehi-
cle roof that is longer or wider than the
luggage carrier itself. (Examples: ply-
wood, paneling, a mattress.) The load
could be violently torn off, causing you
or others to have a collision.
Loading cargo that weighs more than
220 pounds (100 kg) on the luggage
carrier may damage your vehicle.
