4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The SKIS indicator
light will stop flashing, turn on for 3 seconds; then turn
off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.
General Information
The Sentry Key Immobilizer System complies with FCC
rules part 15 and with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
STEERING WHEEL LOCK Ð IF EQUIPPED
Your vehicle may be equipped with a passive steering
wheel lock (manual transmission only). This lock pre-
vents steering the vehicle without the ignition key. If the
steering wheel is moved a half turn in either direction
and the key is not in the ignition, the steering wheel will
lock.
To Manually Lock the Steering Wheel
With the engine running, rotate the steering wheel 1/2
revolution from straight ahead position, turn off the
engine and remove the key. Rotate the steering wheel
slightly in both directions until the lock engages.
To Release the Steering Wheel Lock
Insert the key in the ignition and turn the wheel slightly
to the right or left to disengage the lock.

the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

MIRRORS
Inside Day/Night Mirror
The mirror should be adjusted to center on the view
through the rear window. A two-point pivot system
allows for horizontal and vertical adjustment of the
mirror.
Annoying headlight glare can be reduced by moving the
small control under the mirror to the night position
(toward rear of vehicle). The mirror should be adjusted
while set in the day position (toward windshield).
Inside Automatic Dimming Compass/Temperature
Mirror Ð If Equipped
The automatic day/night mirror is equipped with three
buttons: the left switch for the left LED lamp, the right
switch for the right side LED lamp and the center switch
for the compass/temperature function. Pressing the left
and right switches simultaneously for more than 5 sec-
onds will turn the auto dim function on or off. If the
feature is turned off, it will automatically turn back on
with the next ignition cycle. A green light next to the right
button will indicate when the dimming feature is acti-
vated active. The mirror also senses the backup lamp
circuit, and will automatically disable its self-dimming
feature whenever the transmission gear selector is in the
R (Reverse) position.

15. Coolant Temperature Gauge
Indicates engine coolant temperature. The red
zone to the far right indicates possible overheat-
ing. Seek authorized service immediately if the
gauge operates in the red zone. In U.S. vehicles,
temperature is indicated in degrees fahrenheit; in
Canadian vehicles in degrees centigrade.
16. Airbag Warning Light
This indicator lights and remains lit for 6 to
8 seconds when the ignition is first turned
on. If the light does not come on for 6 to 8
seconds, stays on or comes on while driving,
have the airbag system checked by an authorized
dealer.
17. Check Gauges Warning Light
This light monitors the engine coolant tem-
perature, engine oil pressure, and voltage
gauges. If it detects an extreme condition a
chime will sound and the light will come on. If the
light comes on, check the operation of these gauges for
a malfunction condition.18. Malfunction Indicator Light
This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine,
and automatic transmission control systems.
The light will illuminate when the ignition is in the
ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON, have
the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the ªMalfunction Indicator
Lightº may flash to alert serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.

Clock Setting Procedure
1. Turn the ignition switch to the ON or ACC position
and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
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. It will not start unless the
clutch pedal is pressed to the floor.
WARNING!
You or others around you could be injured if you
attempt to start the engine with a manual transmis-
sion in gear Ð your vehicle will move. Remember,
always push the clutch pedal in fully and shift into
N (Neutral) before attempting to start the engine.
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.
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.
160 STARTING AND OPERATING

TRANSMISSION SHIFTING
5-Speed Manual Overdrive Transmission
Follow the shift pattern on the gearshift knob.
NOTE:The backup lights will come on when your
vehicle is in reverse gear and the ignition is in the ON
position.
WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
²Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, transmission damage may result.
²Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
STARTING AND OPERATING 163

²Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
²Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
²When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
²Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
²During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
²Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
²When ªrockingº a stuck vehicle by shifting between a
forward gear and reverse, do not spin wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
²The manual transmission may be equipped with a
ªReverse Blockerº to prevent inadvertent shifts from
5th gear to Reverse. If you experience difficulty shift-
ing into ªReverseº, make sure that you are not inad-
vertently moving the shift lever toward 5th gear when
shifting into ªReverse.º
Recommended Manual Transmission Shifting
Speeds
The ªShift Indicator Lightº in the instrument cluster
reminds you when to shift to the next higher gear (4.0L
Only). The manufacturer recommends that you use the
SIL for normal driving. The desired shift speeds are listed
in the chart below.

164 STARTING AND OPERATING

Clutch Interlocking Ignition System
Manual transmission vehicles are equipped with a clutch
interlock safety feature. With this feature engaged, you
must depress the clutch pedal to allow cranking of the
engine. To temporarily bypass this safety feature while
off-road driving, which will allow cranking the engine
without depressing the clutch, follow these steps:
1. Locate the instrument panel fuseblock behind the
glove compartment.
2. Put a 20 Amp fuse (optional) in the fuseblock cavity
(f20) marked as Transmission.
NOTE:A fuse is provided in fuseblock cavity (f19)
marked as Spare.
3. Be sure to re-engage the clutch interlock safety feature
by following these steps in reverse order when you are
finished off-road driving.
Automatic Transmission
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) 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.
