A WORD ABOUT YOUR KEYS
The keys for your new vehicle are enclosed in a plastic
bag with the key code number on it. If you received your
keys without the bag, ask your dealer to give you the
number. The key code can also be obtained by the dealer
from your vehicle invoice.
Ignition Key
Insert the key fully, then turn the switch to one of the four
illustrated positions. The key can be inserted or with-
drawn only in the LOCK position. To remove the ignition key on models with an automatic
transmission, place the gearshift lever in P (Park), turn
the ignition key to LOCK, and remove the key.

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 — 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.

13. Oil Pressure Gauge Indicates engine oil pressure. This gauge does not
indicate oil level, and pressure varies with engine
speed, temperature and oil viscosity. Consistent lower
readings indicate possible malfunction. Seek authorized
service.
14. 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, tempera-
ture is indicated in degrees fahrenheit; in Canadian
vehicles in degrees centigrade.
15. 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.
16. 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.
17. 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.

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 — 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

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.
Automatic Shift Controls
188 STARTING AND OPERATING

R (Reverse)
For moving the vehicle rearward. Always stop before
moving the lever to R (Reverse), except when rocking the
vehicle.
N (Neutral)
Engine may be started in this position.
NOTE: Towing the vehicle, coasting, or otherwise driv-
ing with the transmission in N (Neutral) can cause severe
damage to the transmission.
WARNING!
Do not coast in N (Neutral) and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle.
Overdrive (O/D)
For most city and highway driving. The transmission
contains an electronically controlled Overdrive, and will
automatically shift from D (Drive) to O/D (Overdrive) if
the following conditions are present:
•The transmission selector is in D (Drive).
•The O/D OFF switch has not been activated.
•Vehicle speed is above approximately 30 mph (48
km/h).
STARTING AND OPERATING 191

When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup. Overdrive can be locked out by pressing the O/D OFF
switch located on the instrument panel. The O/D OFF
indicator light (on the switch) will illuminate to show
that the switch has been activated. When the indicator
light is on, Overdrive is locked out. Pressing the switch a
second time restores the Overdrive function. The lockout
feature is useful when towing a trailer or carrying a
heavy load.
2 (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.
Overdrive Off Switch
192 STARTING AND OPERATING

WARNING!
Never use P (Park) position with an automatic trans-
mission as a substitute for the parking brake. Al-
ways apply parking brake fully when parked to
guard against vehicle movement and possible injury
or damage.
CAUTION!
•Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK so the steering
wheel and shift lever are released. Otherwise,
damage to steering column or shifter could result.
•Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These prac-
tices can overheat and damage the transmission.
•When “rocking” a stuck vehicle by moving be-
tween D (Drive) and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
STARTING AND OPERATING 193

NOTE:The transmission electronics constantly monitor
the transmission oil temperature. If the transmission gets
too hot, the transmission will change the way it shifts to
help control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough, the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
