2004 JEEP WRANGLER parking brake

NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshafts speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H positions
at a given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2H Position
Rear Wheel Drive High Range Ð Normal street and
highway driving. Dry hard surfaced roads.
STARTING AND OPERATING 171

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.

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the BRAKE warning light in the instrument
cluster will light.
NOTE:The BRAKE warning light indicates only that
the parking brake is applied. It does not indicate the
degree of brake application.
NOTE:If the parking brake is applied and the vehicle is
in motion, the BRAKE warning light will flash and a
chime will sound.
Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position (automatic
transmission) or first gear (manual transmission). Make
certain the transfer case is in gear. Failure to do so may
cause the vehicle to roll and cause damage or injury.
STARTING AND OPERATING 175

WARNING!
²Always fully apply the parking brake when leav-
ing your vehicle, or vehicle may roll and cause
damage or injury. Also be certain to leave a
automatic transmission in P (Park), or a manual
transmission in 1st gear. Make certain the transfer
case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
²If the parking brake is released, and the BRAKE
warning light glows while the ignition switch is
ON or the engine is running, there may be a brake
system problem. Brake pedal travel, effort and
stopping distances may increase, and you should
obtain corrective service immediately.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).
The parking brake should always be applied when the
driver is not in the vehicle.
WARNING!
²Leaving children unattended in a vehicle is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don't leave the keys in the ignition. A child
could operate controls or move the vehicle.
To release the parking brake, pull up slightly, press center
button, then lower lever completely.
176 STARTING AND OPERATING

If the parking brake is not completely released, the
BRAKE warning light will remain on.
NOTE:Your vehicle has automatically adjusting rear
brakes and we do not recommend any adjustment other
than the maintenance performed by your authorized
dealer.
ABOUT YOUR BRAKES
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications
with the engine off), the brakes will still function. The
effort required to brake the vehicle will be much greater
than that required with the power system operating.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
If either of two hydraulic systems lose normal capability,
the remaining system will still function with some loss of
overall braking effectiveness. This will be evident by
increased pedal travel during application and greater
pedal force required to slow or stop.

WARNING!
To use your brakes and decelerate more safely, follow these
tips:
²Do not ªrideº the brakes by resting your foot on the pedal.
This could overheat the brakes and result in unpredictable
braking action, longer stopping distances, or brake damage.
²When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
²Do not downshift on icy or slippery roads, because engine
braking may cause skidding and loss of control.
²Engines may idle at higher speeds during warm-up, which
could cause rear wheels to spin and result in loss of vehicle
control. Be especially careful while driving on slippery
roads, in close-quarter maneuvering, parking or stopping.
Remember, always engage 4-wheel drive when driving on
slippery roads.
²Do not drive too fast for road conditions, especially when
roads are wet or slushy. A wedge of water can build up
between the tire tread and the road. This hydroplaning
action can cause loss of traction, braking ability, and
control. Under such conditions, engage 4-wheel drive.
²After going through deep water or a car wash, brakes may
become wet, resulting in poor performance and unpredict-
able braking action. Dry the brakes by gentle, intermittent
pedal action while driving at very slow speeds.
WARNING!
The weight and position of cargo and passengers can
change the vehicle center of gravity and vehicle han-
dling. To avoid loss of control resulting in personal
injury, follow these guidelines:
²Always place cargo evenly on the cargo floor, and
locate heavier objects as low and as far forward as
possible.
²Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed weight
over or behind the rear axle can cause the rear of the
vehicle to sway.
²Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or become
a dangerous projectile in a sudden stop or collision.
²The rear cargo space is intended for load carrying
purposes only, not for passengers, who should sit in
seats and use seat belts.
²On hardtop models, do not drive with the lift glass
up. On fabric top models, do not drive with the rear
window curtain up unless the side curtains are also
open. This will prevent dangerous exhaust fumes
from entering the vehicle.
178 STARTING AND OPERATING

6. Release brake pedal and ensure that there is no vehicle
movement.
7. Shut the engine off and place the ignition key into the
unlocked OFF position.
8. Shift automatic transmission into P (Park).
9. Apply parking brake.
10. Attach vehicle to the tow vehicle with tow bar.
11. Release parking brake.
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into P (Park) with the transfer case
in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
off prior to shifting the transmission into P (Park)
(refer to steps7±8above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift automatic transmission into N (Neutral) or de-
press clutch pedal on manual transmission.
2. Shift transfer case lever into desired position.
3. Shift automatic transmission into D (Drive) or release
clutch on manual transmissions.
NOTE:When shifting out of transfer case N (Neutral)
on automatic transmission equipped vehicles, turning
the engine off may be required to avoid gear clash.
206 STARTING AND OPERATING

WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
²Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
