vehicle can be used to start and operate the vehicle. The
system will shut the engine off in two seconds if an
invalid Key Fob is used to start the engine.
After turning the ignition switch to the ON/RUN posi-
tion, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the light begins to flash after
the bulb check, it indicates that someone used an invalid
Key Fob to start the engine. Either of these conditions will
result in the engine being shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.CAUTION!
The Sentry KeyImmobilizer system is not compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.

Also, the ORC turns on the Air Bag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Air Bag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.

Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates

vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to feel
the air directed against the windshield. See your autho-
rized dealer for service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell of your
vehicle. Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so that they
cannot slip out of position and interfere with the pedals
or impair safe operation of your vehicle in other ways.

Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
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.
Lane Change Assist
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash
three times then automatically turn off.
Flash-To-Pass
You can signal another vehicle with your headlights by
partially pulling the multifunction lever toward the steer-
ing wheel. This will cause the high beam headlights to
turn on until the lever is released.Multifunction Lever

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Air Bag Warning LightThis light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to the ON/RUN position. If the light is
either not on during starting, stays on, or turns
on while driving, have the system inspected at an autho-
rized dealer as soon as possible. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.

lights or headlights are turned on.
13. Seat Belt Reminder Light When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information. 14. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
