Pull the lever toward you to switch the headlights back to
low beam. If the driver’s door is open, and the headlights
or park lights are left on, the high beam indicator light
will remain illuminated and a chime will sound.
11. Brake Warning LightThis 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 capac-
ity 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 Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer. The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
12. Anti-Lock Brake (ABS) Light
After the ignition is turned on, the Anti-Lock
Brake System (ABS) light illuminates to indicate
function check at vehicle start-up. If the light remains on
after start-up or comes on and stays on at road speeds, it
may indicate that the ABS has detected a malfunction or
has become inoperative. The system reverts to standard
non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning
Light are on, see an authorized dealer immediately. Refer
to “Anti-Lock Brake System” in “Starting And
Operating”.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.
(Continued)
WARNING! (Continued)
•Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave Keyless Enter-N-Go™ in the ACC or ON/
RUN mode. A child could operate power windows,
other controls, or move the vehicle.
Manual Transmission — If Equipped
Apply the parking brake, place the shift lever in NEU-
TRAL, and press the clutch pedal before starting the
vehicle. This vehicle is equipped with a clutch interlock-
ing ignition system. It will not start unless the clutch
pedal is pressed to the floor.
Four-Wheel Drive Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to press the clutch pedal.
418 STARTING AND OPERATING

The “4WD Indicator Light” will illuminate when the
transfer case has been shifted into this mode.
Automatic Transmission — If Equipped
Start the vehicle with the shift lever in the PARK position
(vehicle can also be started in NEUTRAL). Apply the
brake before shifting to any driving range.
Normal Starting
NOTE:Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK/
OFF position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
Tip Start Feature — Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (Below –20°F Or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
