THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized 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 RKE Key Fob, an Ignition Node
Module, Keyless Push Button Ignition and a RF receiver
to prevent unauthorized vehicle operation. Therefore,
only RKE 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 RKE Key
Fob is used to start and operate the vehicle. The system
will shut the engine off in two seconds if an invalid RKE
Key Fob is used to start the engine.
NOTE:A RKE Key Fob that has not been programmed is
also considered an invalid key. During normal operation, after placing the keyless igni-
tion in 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 addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid RKE Key Fob 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
seconds), it indicates that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition must be changed
from the START or ON/RUN position to the OFF posi-
tion. Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the engine
compartment and fuel tank before resetting the system
and starting the engine.
Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Re-
straint Controller (ORC) monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition is placed in the
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

START or ON/RUN position. If the ignition is in the OFF
position or in the ACC position, the air bag system is not
on and the air bags will not inflate.
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. Thediagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, 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.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

483 to 805 km (300 to 500 miles):
•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 136 km/h (85 mph) 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. Running the engine
with an oil level below the add mark can cause severe
engine damageSAFETY 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
cause serious injury or death.
• It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
•
Do not allow people to ride in any area of your vehicle
that is not equipped with seats and seat belts.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 109

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 objects
lodged 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 brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
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.

This light will flash at a fast rate for approximately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly until the vehicle is disarmed.
Oil Pressure Warning Light
Red Telltale
Light What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. 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.

Electronic Throttle Control (ETC) Warning Light
Red TelltaleLight What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is running, the light will either stay on or flash de-
pending on the nature of the problem. Cycle the ignition key 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 engine running, your vehicle will usually be driv-
able; however, see an authorized dealer for service as soon as possible.
If the light continues to flash when the engine 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 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 authorized dealer.
