STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle.
4WD 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 depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.
STARTING AND OPERATING 211

NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P).
Normal Starting
Normal starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the normal starting procedure.
Extreme Cold Weather (below –20°F (–29°C)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.

MANUAL TRANSMISSION
Clutch Interlocking Ignition System
2WD Models Only — Manual transmission vehicles are
equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
4WD Models Only — The exception to this clutch inter-
lock is 4WD models equipped with a manual transmis-
sion. For these models, the clutch interlock feature is
overridden when the vehicle is operated in 4L to enhance
off-road capability. Refer to “Starting Procedures —
Manual Transmission (4WD Models Only)” in this sec-
tion.
6-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the
vehicle, especially on an incline.
Follow the shift pattern on the gearshift knob.
NOTE:The backup lights will come on when your
vehicle is in R (Reverse) gear and the ignition is in the ON
position.
216 STARTING AND OPERATING

AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into P (Park) only after the vehicle has come
to a complete stop.
•Shift into or out of R (Reverse) only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from R (Reverse), P (Park), or N
(Neutral) into any forward gear when the engine
is above idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of P (Park) and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of P
(Park).
220 STARTING AND OPERATING

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE:The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
Be sure the parking brake is firmly set when parked, and the
gear shift lever is in the P (Park) position (automatic
transmission) or R (Reverse) or 1st gear (manual transmis-
sion). When parking on a hill, you should apply the parking
brake before placing the gear shift lever in P (Park), other-
wise the load on the transmission locking mechanism may
make it difficult to move the selector out of P (Park).
Parking Brake
240 STARTING AND OPERATING

WARNING!
•Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also, be certain to leave an automatic trans-
mission in P (Park), a manual transmission in R
(Reverse) or 1st gear. Failure to do so may allow the
vehicle to roll and cause damage or injury.
•Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake or the gear selector lever. Don’t
leave the keys in the ignition. A child could operate
power windows, other controls, or move the vehicle.
•Be sure the parking brake is fully disengaged before
driving, failure to do so can lead to brake problems
due to excessive heating of the rear brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
STARTING AND OPERATING 241
5

WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason, your
foot is on the brake when the vehicle reaches 12 mph
(20 km/h), this check will be delayed until 25 mph
(40 km/h).
The Anti-Lock Brake System pump motor runs during
the self-test and during an ABS stop to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation, this is normal.During off-road use, loss of traction can temporarily
defeat the system and cause the warning light to illumi-
nate. Turn the ignition OFF and ON again to restore
Anti-Lock Brake System function.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
242 STARTING AND OPERATING

Base System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•4 Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full sizespare wheel and tire assembly. The matching full size
spare tire can be used in place of any of the four road
tires.
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. The audible
chime will sound once every ignition cycle for each
condition that it detects. Should this occur, you should
stop as soon as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to the
vehicle’s recommended cold tire pressure. The system
will automatically update, and the “Tire Pressure Moni-
toring Light” will extinguish once the updated tire pres-
sures have been received. The vehicle may need to be
driven for up to 10 minutes above 15 mph (24 km/h) to
receive this information. A low spare tire will not cause
the “Tire Pressure Monitoring Telltale Light” to illumi-
nate or the chime to sound.
