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 ignition keys which have an
embedded electronic chip (transponder) to
prevent unauthorized vehicle operation.
Therefore, only keys that are programmed to
the vehicle can be used to start and operate the
vehicle.
If the vehicle security light is on after the key is
turned to the MAR (ACC/ON/RUN) position, it
indicates that there is a problem with the
electronics.All of the keys provided with your new vehicle
have been programmed to the vehicle
electronics.
NOTE:
A key which 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
Ú
page 274.
IGNITION SWITCH

1. Place the gear selector in PARK.

2. Rotate the key to the STOP (OFF/LOCK)
position.
3. Remove the key from the mechanical ignition switch.

Door Open Warning Light
This indicator will illuminate when one
or more door(s) are not fully closed.
NOTE:
If the vehicle is moving and a door is opened,
there will also be a single chime.
Electronic Throttle Control Warning Light
This warning light will illuminate to
inform of 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 (P) 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.
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
MAR/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.
Transmission Fault Warning Light
This light will illuminate (together with
a message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Temperature Warning Light
This light warns of an overheated
engine condition. If the engine
coolant temperature is too high, this
indicator will illuminate and a single
chime will sound.

If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle.
If the temperature reading does not return to
normal, turn the engine off immediately and call
for service
Ú
page 206.

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
