VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, liftgate flipper glass, and ignition for unautho-
rized operation. When the alarm is activated, the Vehicle
Security Alarm provides both audio and visual signals.
The horn will sound, the headlights, park lamps and/or
turn signals will flash repeatedly for three minutes. If the
disturbance is still present (driver’s door, passenger door,
other doors, ignition) after three minutes, the headlights,
park lamps and/or turn signals will flash for an addi-
tional 15 minutes.
NOTE:The Panic and Security alarms are quite differ-
ent. Please take a moment to activate the Panic and the
Security modes to hear the differences in the horn. In case one should go off in the future, you will need to know
which mode has been activated in order to deactivate it.
Rearming The System
If something triggers the alarm, and no action is taken to
disarm it, the Vehicle Security Alarm will turn off the
horn after three minutes, turn off all of the visual signals
after 15 minutes, and then the Vehicle Security Alarm will
rearm itself.
To Set the Alarm
The alarm will set when you use the Remote Keyless
Entry (RKE) transmitter to lock the doors and liftgate, or
when you use the power door lock switch while the door
is open. After all the doors are locked and closed, the
Vehicle Security Light (located in the instrument cluster)
will flash rapidly for about 16 seconds to signal that the
Vehicle Security Alarm is arming. During this 16 second
arming period, opening any door or the liftgate will

It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted. The diagnostics also record the nature of the
malfunction.
WARNING!
Ignoring the Airbag Warning Light in your instru-
ment panel could mean you won’t have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
Driver and Passenger Airbag Inflator Units
The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator units.
A large quantity of non-toxic gas is generated to inflatethe Advanced Front Airbags. Different airbag inflation
rates are possible, based on the collision type and sever-
ity. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold out
of the way as the bags inflate to their full size. The bags
fully inflate in about 50 to 70 milliseconds. This is about
half of the time it takes to blink your eyes. The bags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides of
the airbag. In this way, the airbags do not interfere with
your control of the vehicle.Supplemental Side Airbag Inflatable Curtain
(SABIC) Inflator Units — If Equipped
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may

NOTE:
•Turning on the high beam headlights turns off the fog
lights.
•A front fog light is a lighting device that provides
illumination in front of the vehicle under conditions of
fog, rain, snow, or dust. The front fog lights supple-
ment the low beams of a standard headlight system.
•Proper aim and adjustment of the front fog lights
should be made to prevent excessive glare for other
drivers.
Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show
proper operation of the front and rear turn signal lights.NOTE:
If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective outside
light bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective.Turn Signal Control

System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep ParkSenseoperating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSense off, the instrument cluster
will display “PARK ASSIST DISABLED.” Further-
more, once you turn ParkSense off, it remains off
until you turn it on again, even if you cycle the ignition
key.
•When you move the shift lever to the REVERSE
position and ParkSense is turned off, the instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSense system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM”. If this
occurs making sure the rear fascia/bumper is free
from snow, ice, mud, dirt and debris, see your autho-
rized dealer.
•Clean the ParkSense sensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt, or debris.
Failure to do so can result in the system not working
properly. ParkSense might not detect an obstacle
behind the fascia/bumper, or it could provide a false
indication that an obstacle is behind the fascia/
bumper.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 123

•Objects must not be within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the instrument cluster.
CAUTION!
•ParkSenseis only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected or not detected at all. Obstacles located
above or below the sensors will not be detected
when they are in close proximity.
•The vehicle must be driven slowly when using Park-
Sense to be able to stop in time when the obstacle is
detected. It is recommended that the driver looks over
his/her shoulder when using ParkSense.
WARNING!
•Drivers must be careful when backing up even
when using the ParkSense Rear Park Assist Sys-
tem. Always check carefully behind your vehicle,
look behind you, and be sure to check for pedes-
trians, animals, other vehicles, obstructions, and
blind spots before backing up. You are responsible
for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
