310 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the keys in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
Start the engine with the shift lever in the NEUTRAL or
PARK position. 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
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Tip Start Feature
Turn the ignition switch to 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 seconds. If this
occurs, turn the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.

STARTING AND OPERATING 313

AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or 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 move the shift lever out of PARK or
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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key to the LOCK position. The key
can only be removed from the ignition when the ignition
is in the LOCK position. Once the key is removed, the
shift lever is locked in PARK.
316 STARTING AND OPERATING

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to the ON or
START position (engine running or not) and the brake
pedal must be pressed.
Four–Speed Automatic Transmission
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only second gear operation. Normal
operation will resume once the transmission temperature
has risen to a suitable level.
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
when moving the shift lever between these gears.
Gear Ranges
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
Shift Lever

STARTING AND OPERATING 317

the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever in the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.
•It is dangerous to move the shift lever out of PARK
or 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 right foot is firmly on the brake pedal.
REVERSE
This range is for moving the vehicle rearward. Use this
range only after the vehicle has come to a complete stop.
NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake and
shift the transmission into PARK if you must leave the
vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with shift lever in NEUTRAL can result in
severe transmission damage. Refer to “Recreational Tow-
ing” in “Starting and Operating” and “Towing a Disabled
Vehicle” in “What To Do In Emergencies” for further
information.
DRIVE
This range is used for most city and highway driving.
318 STARTING AND OPERATING

WARNING!
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging
the parking brake. The transfer case NEUTRAL
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.
•Always engage the parking brake when powering
down the vehicle if the “SERV 4WD Warning
Light” is illuminated. Not engaging the parking
brake may allow the vehicle to roll, which may
cause personal injury.(Continued)
WARNING! (Continued)
•Since four-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit. You or others could be injured.
