Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON position, and the brake
pedal is depressed.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visible signals. For the
first three minutes the horn will sound and the headlights
and security telltale will flash repeatedly. For an addi-
tional 15 minutes only, the headlights and security telltalewill flash. The engine will run only if a valid Sentry Keyt
is used to start the vehicle. Use of the Sentry Keytwill
disable the alarm.
Rearming of the System:
The Security Alarm System will rearm itself after the 15
additional minutes of headlights and security telltale
flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
To Set the Alarm
The alarm will set when you use the power door locks, or
use the Remote Keyless Entry (RKE) Transmitter to
LOCK the doors. After all the doors are locked and
closed, the SECURITY light in the instrument cluster will
flash rapidly to signal that the system is arming. The
SECURITY light in the instrument panel cluster will flash
rapidly for about 16 seconds to indicate that the alarm is

To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other abrasive materials to clean the lenses.
Daytime Running Lights (Canada Only and Fleet
Vehicles)
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear
except PARK. This provides a constant9Lights ON9
condition until the ignition is turned OFF. The lights
illuminate at less than 50% of normal intensity. If the
parking brake is applied, the Daytime Running Lights
(DRL) will turn OFF. Also, if a turn signal is activated, the
DRL lamp on the same side of the vehicle will turn off for
the duration of the turn signal activation. Once the turn
signal is no longer active, the DRL lamp will illuminate.
Lights-on Reminder
If the headlights, parking lights, or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver's door is opened.
Fog Lights Ð If Equipped
The fog lights are turned ON by placing the
headlight rotary control in the parking light or
headlight position and pushing in the headlight
rotary control. The fog lights will operate only when the
parking lights are on or when the vehicle headlights are
on low beam. An indicator light located in the instrument
cluster will illuminate when the fog lights are on. The fog
lights will turn off when the switch is pushed a second
time, when the headlight switch is rotated to the OFF
position, or the high beam is selected.

NOTE:The Electronic Speed Control System has been
designed to shut down if multiple speed control switch
buttons (i.e., SET and CANCEL) are operated simulta-
neously, in order to ensure proper operation. The system
can be reactivated by pushing the speed control switch
ON/OFF button and re-establishing the desired vehicle
SET speed.
To Activate
Push the ON/OFF button to the ON position. An indi-
cator light in the instrument cluster illuminates when the
system is on.
To Set At A Desired Speed
When the vehicle has reached the desired speed, press
and release the SET button. Release the accelerator and
the vehicle will operate at the selected speed.
To Deactivate
A soft tap on the brake pedal, normal braking, clutch
pressure while slowing the vehicle, or pressing the CAN-
CEL button will deactivate speed control without erasing
the memory. Pushing the ON/OFF button to the OFF
position or turning off the ignition erases the memory.
WARNING!
Leaving the speed control ON when not in use is
dangerous. You could accidentally set the system to
cause it to go faster than you want. You could lose
control and have an accident. Always leave the sys-
tem OFF when you aren't using it.

17. Malfunction Indicator Light (MIL)
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for
five seconds, and remain on until the vehicle is started. If
the bulb does not come on during starting, have the
condition investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on.
194 UNDERSTANDING YOUR INSTRUMENT PANEL

If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicatesthat the anti-lock portion of the brake system is not
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed.
20. Cargo Light
The Cargo Light will illuminate when the
Cargo Light is activated by pressing the Cargo
Light Button on the headlight switch.
21. Electronic Throttle Control (ETC)
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected, the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your authorized dealer for service as soon
as possible. If the light is flashing when the engine is
running, immediate service is required and you may
