is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, 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 Vehicle Security Light
begins to flash after the bulb check, it indicates that someone used an invalid key to try 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 Key
Immobilizer 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 keys provided with your new vehicle have
been programmed to the vehicle electronics.

NOTE:Changes or modifications not expressly ap-
proved by the party responsible for compliance could
void the user’s authority to operate the equipment.
If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. Weak battery in RKE transmitter. The expected life of
the battery is from one to two years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m). NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and RKE transmitter
may reduce this range.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK.
•Doors closed.
•Hood closed.
•Liftgate closed.
•Hazard switch off.
•Brake switch inactive (brake pedal not pressed).
•Ignition key removed from ignition switch.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 27

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•How various systems in your vehicle were operating;
•Whether or not the driver and passenger safety belts
were buckled/fastened;
•How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
•How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation.

WARNING! (Continued)
•If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set
the blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
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.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING! (Continued)
•Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Ob-
jects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
92 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

5. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the PARK position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate 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 first turned to ON/RUN and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer. 6. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, 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 MIL 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.
226 UNDERSTANDING YOUR INSTRUMENT PANEL

If the vehicle electronics sense that the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on, a
continuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
11. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If EquippedThe “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected. NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to
ON/RUN.
•Each time the ignition is turned to ON/RUN, the ESC
system will be ON, even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
12. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on
briefly as a bulb check. If the light stays on or comes on
while driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
