warning light JEEP WRANGLER 2004 TJ / 2.G Owners Manual

WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you
have airbags.
²Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
Airbag System Components
The airbag system consists of the following:
²Airbag Control Module (ACM)
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Steering Wheel And Column
²Instrument Panel
²Crash Sensor
²Interconnecting Wiring
²Knee Impact Bolsters
²Passenger Airbag ON/OFF Switch (If Equipped)
How The Airbag System Works
²
TheAirbag Control Module (ACM)determines if a
frontal collision is severe enough to require the airbags
to inflate.
²The ACM will not detect side, roll over, or rear
impacts.
²The ACM also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON position. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
ignition key is in the OFF or ACC position, or not in
the ignition, the airbags are not on and will not inflate.
24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²Also, the ACM turns on the ªAirbag Warning Lightº in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously. If the
ACM detects a malfunction, the ªAirbag Warning
Lightº will illuminate for a minimum of 12 seconds
and will remain illuminated as long as the malfunction
exists.
WARNING!
Ignoring the ªAirbag Warning Lightº in your instru-
ment panel could mean you won't have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and in the
instrument panel. When the ACM detects a collision
requiring the airbags, it signals the inflator units. A
large quantity of nontoxic gas is generated to inflate
the airbags. The airbag covers separate and fold out of
the way as the bags inflate to full size. The bags fully
inflate in about 50 milliseconds. This is about half of
the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger. The driver's front airbag gas is vented
through the airbag material towards the instrument
panel. The passenger's front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
²TheKnee Impact Bolstershelp protect the knees and
position the driver and front passenger's for the best
interaction with the front airbag.

To Shut Off the Passenger Airbag
1. Turn ignition to OFF position.
2. Remove the water-resistant plug.
3. Place the ignition key in the Passenger Airbag ON/
OFF Switch, press inward and turn the key to the right to
the OFF position. This will shut off the passenger airbag.
4. Reinstall the water-resistant plug.
NOTE:When the Passenger Airbag ON/OFF Switch is
in the OFF position, a indicator light will illuminate when
the ignition is ON. If the indicator light does not illumi-
nate for 3 seconds after the ignition is turned ON, or
when the Passenger Airbag ON/OFF Switch is turned
OFF (while ignition is in the ON position), have an
authorized dealer service the system immediately.
To Turn On the Passenger Airbag
1. Turn ignition to OFF position.
2. Remove the water-resistant plug.3. Place the ignition key in the Passenger Airbag ON/
OFF Switch, press inward and turn the key to the left to
the ON position. This will turn on the passenger airbag.
4. Reinstall the water-resistant plug.
NOTE:Do not turn the Passenger Airbag ON/OFF
Switch on or off with the ignition in the ON/RUN or
START positions, as the ACM could cause the ªAirbag
Warning Lampº to illuminate.
If A Deployment Occurs
The airbag system is designed to deploy when the impact
sensors detect a moderate-to-severe frontal collision, to
help restrain the driver and right front passenger, and
then to immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or frame.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has airbags.
Airbag Warning Light
You will want to have the airbags ready to inflate for your
protection in an collision. While the airbag system is
designed to be maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
²The ªAirbag Warning Lightº does not come on or
flickers during the 6 to 8 seconds when the ignition
switch is first turned on.
²The ªAirbag Warning Lightº remains on or flickers
after the 6 to 8 second interval.
²The ªAirbag Warning Lightº flickers or comes on and
remains on while driving.
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time-babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle isstopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
²On hardtop models, keep the tailgate window closed
when driving your vehicle. On fabric top models, do
not drive with the rear window curtain up unless the
side curtains are also open. This will prevent carbon
monoxide and other poisonous exhaust gases from
entering the vehicle.
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a indicator check when the ignition switch is
first turned on. If the indicator is not lit during starting,
have it serviced. If the light stays on or comes on while
driving, have the system checked by an authorized
dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.

The overhead light comes on when a door is opened. It
may also be turned on by rotating the control for the
dimmer switch on the muti-function control lever fully
upward.
The overhead light will automatically turn off in about 20
minutes if a door is left open or the dimmer control is left
in the dome light position. Turn the ignition switch ON to
restore the overhead light operation.
Daytime Brightness Feature
Certain instrument panel components (odometer, radio
display) can be illuminated at full brightness during the
daytime. This can be helpful when driving with your
headlights on during the daytime such as in a parade or
a funeral procession. To activate this feature, rotate the
left stalk one detent lower than the dome light.
Multi-Function Control Lever
The multi-function control lever controls the operation of
the parking lights, headlights, headlight beam selection,
passing light, fog lights, instrument panel light dimming,
and turn signals.
56 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. (If the vehicle speed drops below 30 mph (48
km/h), the Speed Control will automatically disengage).
If this happens, you can push down on the accelerator
pedal to maintain the desired speed.
WARNING!
Leaving the Speed Control on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always turn the system
off when you are not using it.
CIGAR LIGHTER AND ASHTRAYS Ð IF
EQUIPPED
The vehicle may be equipped with a cigar lighter recep-
tacle, element, and ashtray (Smoker's Package Only). The
cigar lighter will be located in the lower instrument panel
(near the heater controls), and the removable ashtray will
be located in the center console.
62 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
