STARTING AND OPERATING 413

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.
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
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.

Manual Transmission Shift Speeds in MPH (KM/H)
Engine Speeds 1 to 2 2 to 3 3 to 4 4 to 5 5 to 6 3.6L Accel. 15 (24) 24 (39) 34 (55) 47 (76) 56 (90)
Cruise 10 (16) 19 (31) 27 (43) 37 (60) 41 (66)
NOTE: Vehicle speeds shown in the chart above are for
2H and 4H only, vehicle speeds in 4L would be signifi-
cantly less.
Downshifting
Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip, and the vehicle could skid.
420 STARTING AND OPERATING

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:
•After selecting any gear range, wait a moment to allow
the selected gear to engage before accelerating. This is
especially important when the engine is cold.
• If there is a need to restart the engine, be sure to cycle
the ignition to the OFF position before restarting.
Transmission gear engagement may be delayed after
restarting the engine if the key is not cycled to the OFF
position first.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range.
When parking on a level surface, you may place the shift
lever in PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
426 STARTING AND OPERATING

WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.

Actual Gear(s)
Allowed 1 1-2 1-3 1-4 1-5
NOTE: To select the proper gear position for maximum
deceleration (engine braking), tap the shift lever to the
left (-) repeatedly as the vehicle slows. The transmission
will shift to the range from which the vehicle can best be
slowed down.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear). The transmission will
automatically shift into Overdrive if the following con-
ditions are present:
• the shift lever is in the DRIVE position,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the accelerator.
432 STARTING AND OPERATING

FOUR–WHEEL DRIVE OPERATION
(COMMAND-TRAC I® OR ROCK-TRAC®)
WARNING!
Failure to engage a position completely can cause
transfer case damage or loss of power and vehicle
control. You could have a collision. Do not drive the
vehicle unless the transfer case is fully engaged.
Operating Instructions/Precautions
The transfer case provides four mode positions:
•2H (Two-wheel drive high range)
• 4H (Four-wheel drive high range)
• N (Neutral)
• 4L (Four-wheel drive low range) The transfer case is intended to be driven in the 2H
position for normal street and highway conditions such
as hard-surfaced roads.
