2004 JEEP WRANGLER brake light

WARNING!
To help avoid personal injury, follow these tips:
²Never reach through the steering wheel to operate
steering column controls. Injury to your hands or
loss of vehicle control may result.
²If the engine stalls or power assist fails due to a
malfunction, vehicle steering and braking will
require greater effort.
ANTI-LOCK BRAKE SYSTEM Ð IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason, your
foot is on the brake when the vehicle reaches 12 mph (20
km/h), this check will be delayed until 25 mph (40
km/h).
The Anti-Lock Brake System pump motor runs during
the self-test and during an ABS stop to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation, this is normal.
During off-road use, loss of traction can temporarily
defeat the system and cause the warning light to illumi-
nate. Turn the ignition OFF and ON again to restore
Anti-Lock Brake System function.
STARTING AND OPERATING 179
5

Don't shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels
and traction will be lost.
Do not downshift on icy or slippery roads because engine
braking may cause skidding and loss of control.
When driving on soft sand, reduce your tire pressure to
15 psi (103 kPa) minimum to allow greater tire surface
area. You must return the tires to normal air pressure
before driving on pavement or other hard surfaces.
NOTE:Reduced tire pressures below 15 psi (103 kPa)
may cause tire unseating and loss of air pressure.
Hill Climbing
Before climbing a steep hill,change transmission to a
lower gear and shift the transfer case to 4L (Low). Use
first gear and 4L (Low) for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brake. Restart the engine and shift
to R (Reverse). Back up slowly down the hill allowing the
compression braking of the engine and transmission tohelp regulate your speed. If the brakes are required to
control vehicle speed, apply them lightly and avoid
locking or skidding the tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back care-
fully straight down a hill in R (Reverse) gear. Never
back down a hill in N (Neutral) or with the clutch
pedal depressed, using only the brake.
Remember, never drive diagonally across a hill, always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels sharply left and right. This will
provide fresh ªbiteº into the surface and will usually
provide traction to complete the climb.
182 STARTING AND OPERATING

²The weight of any other type of cargo or equipment
put in or on your vehicle.
Remember that everything put in or on the trailer adds to
the load on your vehicle.
Warranty Requirements
The manufacturer's warranty will apply to vehicles used
to tow trailers for noncommercial use, however the
following conditions must be met:
²The ªDº Overdrive range can be selected when tow-
ing. However, if frequent shifting occurs move the
shift lever to the next lower position to eliminate
excessive automatic transmission shifting. This action
will also reduce the possibility of transmission over-
heating and provide better engine braking. Refer to
ªTransmission Shiftingº in this section for additional
information.
²A load equalizing hitch is recommended for loaded
trailer weights above 1,000 lbs (454 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Connecting trailer brakes to your vehicle's hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
²Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
mandatory for motoring safety.
²Follow the maintenance intervals in schedule ªBº for
changing the automatic transmission fluid and filter, if
you REGULARLY tow a trailer for more than 45
minutes of continuous operation.
STARTING AND OPERATING 203
5

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.
WHAT TO DO IN EMERGENCIES 217
6

WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the BRAKE warning light shows system failureBe sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake fluid level
should be checked when pads are replaced. However,
low fluid level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended brake fluid, refer
to Recommended Fluids, Lubricants, and Genuine Parts
for correct fluid type.
WARNING!
²Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
²Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
244 MAINTAINING YOUR VEHICLE

NOTE:Most vehicles are operated under the conditions
listed for Schedule ªB.º
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule ªB.º
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²
Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent, add as required.
Once a Month
²
Check the tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of the coolant reservoir, brake
master cylinder, and transmission, and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²
Change the engine oil filter.
²Inspect the exhaust system.
²Inspect brake hoses.
²Check the coolant level, hoses, and clamps.
²Inspect manual transmission fluid level Ð if
equipped.
