ELECTRICAL POWER OUTLET
To the right of the cigar lighter (if equipped) is the 12 volt
power outlet. The outlet is connected directly to the
battery, items plugged into this outlet may discharge the
battery and/or prevent engine starting. The outlet in-
cludes a tethered cap labeled with a battery symbol
indicating the power source.
Electrical Outlet Use With Engine Off
WARNING!
²Many accessories that can be plugged in draw
power from the vehicle's battery, even when not
in use (i.e. cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
²Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
²After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
alternator to recharge the vehicle's battery.
²Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or acces-
sory bracket from the plug. Improper use of the
power outlet can cause damage not covered by
your warranty.

NOTE:Before lowering windshield, disconnect the
electrical connector for the inside Compass/Temperature
mirror (if equipped).
If required for certain off-road uses, the side bars can be
removed and the windshield folded down. However, the
protection afforded by these features is then lost. If you
remove the side bars and fold down the windshield,
drive slowly and cautiously. It is recommended that the
speed of the vehicle be limited to 10 mph (16 km/h), with
low range operation preferred, if you are driving off-road
with the windshield folded down.
Raise the windshield and reinstall the side bars as soon as
the task that required their removal is completed and
before you return to on-road driving. Both you and your
passenger should wear seat belts at all times, on-road and
off-road, regardless of whether the windshield is raised
or folded down.Outside rear view mirrors are mounted on the doors. If
you choose to remove the doors, see your authorized
dealer for a replacement cowl-mounted outside mirror.
Federal law requires outside mirrors on vehicles for
on-road use.
NOTE:If the doors are removed, the courtesy lights
will remain on. To turn these lights off, remove fuse #4 in
the fuse panel. Refer to ªFuse Panelº in Section 7 of this
manual.

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.

WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
After Starting
The idle speed will automatically decrease as the engine
warms up.
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.
ENGINE BLOCK HEATER Ð 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 tie rod
between the radiator grille and the dash panel.
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 0ÉF (-18ÉC) are
expected to last for several days.
162 STARTING AND OPERATING

Set the parking brake, place an automatic transmission in
P (Park) (or N (Neutral) for a manual transmission). Turn
off lights, heater, and other electrical loads. Observe
charge indicator in the battery. If indicator is light or
yellow, replace the battery.
CAUTION!
Use the ªJump Startingº procedure only when the
charge indicator is dark in the center. Do not attempt
jump starting when the battery charge indicator is
bright or yellow. If the charge indicator is dark and
has a green dot in the center, failure to start is not
due to a discharged battery and the cranking system
should be checked.
1. Attach one end of the jumper cable to the positive
terminal of the discharged battery and the other end of
the same cable to the positive terminal of the booster
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
2. Connect one end of the other jumper cable to the
negative terminal of the booster battery. Connect the
other end of the jumper cable to a good ground on the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.

WARNING!
²Do not connect the cable to the negative terminal
of the discharged battery. The resulting electrical
spark could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting to jump start.
3. Take care that the clamps from one cable do not touch
clamps from the other cable. Do not lean over the battery
when making the connection. The negative connection
must provide good electrical conductivity and current
carrying capacity.4. After the engine is started or if the engine fails to start,
the cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine
ground.
b. Disconnect the negative cable at the negative
terminal on the booster battery.
c. Disconnect the cable from the positive terminals
of both batteries.
WARNING!
Any procedure other than above could result in:
²Personal injury caused by electrolyte squirting
out the battery vent.
²Personal injury or property damage due to battery
explosion.
²Damage to charging system of booster vehicle or
of immobilized vehicle.
