30 GETTING TO KNOW YOUR VEHICLE
SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition and
a RF receiver to prevent unauthorized vehicle operation.
Therefore, only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The system
cannot reprogram a key fob obtained from another vehicle.
After turning the ignition switch to the ON/RUN position,
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 addi-
tion, if the light begins to flash after the bulb check, it indi -
cates that someone attempted to start the engine with an
invalid key fob. In the event that a valid key fob is used to
start the engine but there is an issue with the vehicle elec -
tronics, the engine will start and shut off after two seconds. If the vehicle security light turns on during normal vehicle
operation (vehicle running for longer than ten seconds), 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.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Key Programming
Programming key fobs may be performed at an authorized
dealer.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

Front Fog Lights — If Equipped
To activate the front fog lights, turn on the parking lights or
low beam headlights and push in the center of the headlight
switch control knob. Pushing the headlight switch control
knob a second time will turn the front fog lights off.Front Fog Light Switch
Turn Signals

each side of the instrument cluster display will 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 — If Equipped
Tap the multifunction 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.

— Air Bag Warning Light
This warning light will illuminate to indicate a fault with the
air bag, and will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or ACC/
ON/RUN position. This light will illuminate with a single
chime when a fault with the air bag has been detected, it will
stay on until the fault is cleared. If the light is either not on
during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible.
— Brake Warning Light
This warning 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.
The dual brake system provides a reserve braking capacity in
the event of a failure to a portion of the hydraulic system. A
leak in either half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when the brake
fluid level in the master cylinder has dropped below a spec
-
ified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The vehicle
should have service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

— Battery Charge Warning Light
This warning light will illuminate when the battery is not
charging properly. If it stays on while the engine is running,
there may be a malfunction with the charging system.
Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine oil
pressure. If the light turns on while driving, stop the vehicle,
shut off the engine as soon as possible, and contact an autho -
rized dealer. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil
temperature is high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. Wait
for oil temperature to return to normal levels. — Electronic Throttle Control (ETC) Warning Light
This warning light will illuminate to indicate a problem with
the Electronic Throttle Control (ETC) system. If a problem is
detected while the vehicle is running, the light will either
stay on or flash depending on the nature of the problem.
Cycle the ignition when the vehicle is safely and completely
stopped and the transmission is placed in the PARK position.
The light should turn off. If the light remains on with the
vehicle running, your vehicle will usually be drivable;
however, see an authorized dealer for service as soon as
possible.
NOTE:
This light may turn on if the accelerator and brake pedals are
pressed at the same time.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have the
system checked by an authorized dealer.

Yellow Warning Lights
— Adaptive Cruise Control (ACC) Fault Warning Light
— If Equipped
This warning light will illuminate to indicate a fault in the
ACC system. Contact a local authorized dealer for service.
For further information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Air Suspension Fault Warning Light — If Equipped
This light will illuminate when a fault is detected with the air
suspension system.
— Engine Check/Malfunction Indicator Warning Light
(MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control
systems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from OFF
to ON/RUN, have the condition checked promptly. Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the vehicle
will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.

vated when the multifunction lever is moved down (left) or
up (right). NOTE:
• A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either indi -
cator flashes at a rapid rate.
• If equipped with fog lamps, the fog lamp on the side of the activated turn signal will also illuminate to provide addi -
tional light when turning.

194 GETTING TO KNOW YOUR INSTRUMENT PANEL
NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi-
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about ten seconds and thenreturn to being fully illuminated until you turn OFF the
ignition or start the engine. This means that your
vehicle's OBD II system is not ready and you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off position
or start the engine. This means that your vehicle's OBD
II system is ready and you can proceed to the I/M
station. If your OBD II system is
not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready.
Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper -
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
