2004 JEEP WRANGLER warning light

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.

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.

has been opened, and will remain on for 20 seconds after
exiting the vehicle.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.The trip odometer shows individual mileage up to 999.9
miles (1 600 km). To switch from odometer to trip
odometer, press the trip odometer button.
21. Anti-Lock (ABS) Warning Light
After ignition is turned on, illuminates to indi-
cate function check at vehicle start-up. If light
remains on after start-up or comes on and stays on at
road speeds, it may indicate that the ABS has detected
a malfunction or has become inoperative. The system
reverts to standard non-anti-lock brakes.
If both the red BRAKE warning light and the amber ABS
warning light are on, see your dealer immediately. Refer
to ªAnti-Lock Brake Systemº in Section 5 of this manual.
22. Brake Warning Light
After ignition is turned on, illuminates to in-
dicate function check at vehicle start-up. Indi-
cates parking brake is applied. If the light stays

for approximately two seconds. The light should then
turn off unless the parking brake is applied or a brake
fault is detected. If the light does not illuminate, have the
light inspected by an authorized dealer.
23. Low Fuel Warning Light
When the fuel level reaches approximately 2 U.S.
Gallons (7.6L) this light will come on and remain
on until fuel is added. The ªLow Fuel Warning
Lightº may turn on and off again, especially during
and after hard braking, accelerations, or turns. This
occurs due to the shifting of the fuel in the tank.
24. Fuel Cap Indicator
This symbol indicates the side of the vehicle
where the fuel cap is located.25. Fuel Gauge
The pointer shows the level of fuel in the fuel tank. When
the fuel gauge pointer initially moves to E, for your
safety, approximately 2 U.S. Gallons (7.6L) of fuel remain.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.

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

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 (Over-
drive) if the following conditions are present:
²
The transmission selector is in D (Drive).
²The O/D OFF switch has not been activated.
²Vehicle speed is above approximately 30 mph (48
km/h).
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.
168 STARTING AND OPERATING

NOTE:Shifting into or out of 4L is possible with the
vehicle completely stopped, however, difficulty may oc-
cur due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth align-
ment and shift completion to occur. The preferred
method is with the vehicle rolling at 2 to 3 mph (3 to 5
km/h). Avoid attempting to engage or disengage 4L with
the vehicle moving faster than 2 to 3 mph (3 to 5 km/h).
WARNING!
Failure to engage a position completely can cause
transfer case damage or loss of power and vehicle
control. You could have an injury accident. Do not
drive the vehicle unless the transfer case is fully
engaged.
TRAC-LOKŸ REAR AXLE
The Trac-LokŸ rear axle provides a constant driving
force to both rear wheels and reduces wheel spin caused
by the loss of traction at one driving wheel. If traction
differs between the two rear wheels, the differential
automatically proportions the usable torque by providing
more torque to the wheel that has traction.
Trac-LokŸ is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maxi-
mum traction. When starting with only one rear wheel on
an excessively slippery surface, slight application of the
parking brake may be necessary to gain maximum trac-
tion.
