STARTING AND OPERATING 415

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.
5
STARTING AND OPERATING 419

After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is found under the hood
bundled in front of the battery tray.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt AC
electrical cord could cause electrocution.
MANUAL TRANSMISSION — IF EQUIPPED
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.
422 STARTING AND OPERATING

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.
CAUTION!
•Skipping gears and downshifting into lower gears at
higher vehicle speeds can damage the engine and

CAUTION! (Continued)
clutch systems, Any attempt to shift into lower gear
with clutch pedal depressed may result damage to
the clutch system. Shifting into lower gear and
releasing the clutch may result in engine damage.
•When descending a hill, be very careful to down-
shift one gear at a time to prevent overspeeding the
engine which can cause engine damage, and/or
clutch damage, even if the clutch pedal is pressed. If
transfer case is in low range the vehicle speeds to
cause engine and clutch damage are significantly
lower.
•Failure to follow the maximum recommended
downshifting speeds may cause the engine damage
and/or damage the clutch, even if the clutch pedal is
pressed.
•Descending a hill in low range with clutch pedal
depressed could result in clutch damage

STARTING AND OPERATING 425

Reverse Shifting
To shift into REVERSE, bring the vehicle to a complete
stop. Press the clutch and pause briefly to allow the gear
train to stop rotating. Beginning from the NEUTRAL
position, move the shift lever in one quick, smooth
motion straight across and into the REVERSE area (the
driver will feel a firm “click” as the shifter passes the
“knock-over”). Complete the shift by pulling the shift
lever into REVERSE.
The “knock-over” provides a resistance to the driver
from accidentally entering the REVERSE shift area and
warns the driver that they are about to shift the trans-
mission into REVERSE. Due to this feature, a slow shift to
REVERSE can be perceived as a high shift effort.
AUTOMATIC TRANSMISSION — IF EQUIPPED
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 between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.

STARTING AND OPERATING 427

WARNING!
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the ignition key.
Once the key is removed, the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion key and lock your vehicle.

seriously or fatally injured. Children should be

or the shift lever.
• Do not leave the ignition key/Key Fob in or near
the vehicle, or in a location accessible to children. A
child could operate power windows, other controls,
or move the vehicle.
