12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!(Continued)
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove the Key Fob from vehicle, place the ignition
in the OFF and lock all doors when leaving the
vehicle unattended.
SENTRY KEY®
The Sentry Key® Immobilizer System prevents unau-
thorized 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 with a factory-mated Remote
Keyless Entry (RKE) transmitter, an Ignition Node Mod-
ule, Keyless Ignition Node (KIN) 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 will not allow
the engine to crank if an invalid Key Fob is 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.
NOTE:A Key Fob that has not been programmed is also
considered an invalid key.
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 light begins to flash after
the bulb check, it indicates that someone used an invalid

If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. A weak battery in the transmitter. The expected life of
the battery is a minimum of three 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 the RKE trans-
mitter 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
•HAZARD switch off
•BRAKE switch inactive (brake pedal not pressed)
•Battery at an acceptable charge level
28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition is first placed in the
ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenancefree, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
•The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition is first
placed in the ON/RUN position.
•The Air Bag Warning Light remains on after the four to
eight-second interval.
•The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.

100 to 300 miles (161 to 483 km):
•Depress the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration in lower
gears (1st to 3rd gears).
•Avoid aggressive braking.
•Drive with the engine speed less than 5,000 RPM.
•Maintain vehicle speed below 70 mph (112 km/h) and
observe local speed limits.
300 to 500 miles (483 to 805 km):
•Exercise the full engine rpm range, shifting manually
(paddles or gear shift) at higher rpms when possible.
•Do not perform sustained operation with the accelera-
tor pedal at wide open throttle.
•Maintain vehicle speed below 85 mph (136 km/h) and
observe local speed limits.For the first 1500 mi (2414 km):
•Do not participate in track events, sport driving
schools, or similar activities during the first 1500 mi
(2414 km).
NOTE:Check engine oil with every refueling and add if
necessary. Oil and fuel consumption may be higher
through the first oil change interval.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 107

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 seat 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 seat
belt or retractor condition, replace the seat 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

Door Latches
Check for proper 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 (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. 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.3. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
4. High Beam Indicator
Indicates that headlights are on high beam.
