Satellite Antenna
To ensure optimum reception, do not place items on the
roof around the rooftop antenna location or strap items to
the trunk lid around the trunk lid antenna (if equipped).
Metal objects placed within the line of sight of the
antenna will cause decreased performance. Larger lug-
gage items such as bikes should be placed as far rearward
as possible, within the loading design of the rack. Do not
place items directly on or above the antenna.
Reception Quality
Satellite reception may be interrupted due to one of the
following reasons.
•The vehicle is parked in an underground parking
structure or under a physical obstacle.
•Dense tree coverage may interrupt reception in the
form of short audio mutes.
•Driving under wide bridges or along tall buildings can
cause intermittent reception.
•Placing objects over or too close to the antenna can
cause signal blockage.

lation system in this vehicle consist of a series of rotary
knobs, and a push-button. These comfort controls can be
set to obtain desired interior conditions.
Blower Control
The rotary knob on the left controls the blower and can be
set in one of four positions from Low to High.
Temperature Control
The degree of comfort can be selected by rotating the
temperature control knob on the right. The coldest tem-
perature setting is fully counterclockwise and the warm-
est setting fully clockwise. The knob can be positioned at
any detent.
Air Conditioning Operation

normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
Mode Control
The mode selector (the center rotary knob and the
push-button above it) can be set in any of the following
positions:
OFF
This position turns off the blower motor and outside
air will not pass through any outlets.
Recirculate (Max A/C)
Air flows through the outlets located in the
instrument panel. Allows for circulation of
interior air only which will cool the cabin
faster. This setting can be used in very hot
weather to maximize the effect of the air conditioner. This
mode can also be used to temporarily block out outsideodors, smoke, and dust. Slight airflow from the floor
outlets and the defrost outlets, located at the base of the
windshield, may be noticed.
Panel
Air flows through the outlets located in the instru-
ment panel. Slight airflow from the defrost outlet,
located at the base of the windshield, may be noticed.
Bi-Level
Air flows through the outlets located in the instru-
ment panel, on the floor, and in the rear of the center
console. Slight airflow from the defrost outlet, located at
the base of the windshield, may be noticed.
Floor
Air flows through the floor outlets located under
the instrument panel and through the outlets lo-
cated in the rear of the center console. Slight airflow from
the defrost outlet, located at the base of the windshield,
may be noticed. The air conditioning system has been

208 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
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, which requires the clutch to
be fully depressed before starting the vehicle.
4WD 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 depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
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.
STARTING AND OPERATING 211

NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P).
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.
Extreme Cold Weather (below –20°F (–29°C)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
Ignition Key Positions
212 STARTING AND OPERATING

CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant 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 cord is found under the hood
clipped to the heater line on the left side of the engine
(3.7L Engines).
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.

MANUAL TRANSMISSION
Clutch Interlocking Ignition System
2WD Models Only — Manual transmission vehicles are
equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
4WD Models Only — The exception to this clutch inter-
lock is 4WD models equipped with a manual transmis-
sion. For these models, the clutch interlock feature is
overridden when the vehicle is operated in 4L to enhance
off-road capability. Refer to “Starting Procedures —
Manual Transmission (4WD Models Only)” in this sec-
tion.
6-Speed Manual Transmission
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.
Follow the shift pattern on the gearshift knob.
NOTE:The backup lights will come on when your
vehicle is in R (Reverse) gear and the ignition is in the ON
position.
216 STARTING AND OPERATING

AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into P (Park) only after the vehicle has come
to a complete stop.
•Shift into or out of R (Reverse) only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from R (Reverse), P (Park), or N
(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 shift the selector lever out of P
(Park) or N (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.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of P (Park) and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of P
(Park).
