2004 JEEP WRANGLER wheel

2 (Second)
For moderate grades and to assist braking on dry
pavement or in mud and snow. Begins at a stop in low
gear with automatic upshift to 2nd gear. Will not shift
to 3rd.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or
on steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.
WARNING!
Never use P (Park) position with an automatic trans-
mission as a substitute for the parking brake. Al-
ways apply parking brake fully when parked to
guard against vehicle movement and possible injury
or damage.
CAUTION!
²Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK so the steering
wheel and shift lever are released. Otherwise,
damage to steering column or shifter could result.
²Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These prac-
tices can overheat and damage the transmission.
²When ªrockingº a stuck vehicle by moving be-
tween D (Drive) and R (Reverse), do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.

Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
FOUR±WHEEL DRIVE OPERATION
(COMMAND-TRACŸ OR ROCK-TRACŸ) Ð IF
EQUIPPEDOperating Instructions/Precautions
The transfer case provides four mode positions Ð two
(rear) wheel drive high range, four wheel drive high
range, neutral, and four wheel drive low range.
This transfer case is intended to be driven in the two
wheel drive (2H) position for normal street and highway
conditions such as dry hard surfaced roads.
In the events when additional traction is required, the
transfer case 4H and 4L positions can be used to lock the
front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by simply moving the shift lever to these
positions. The 4H and 4L positions are intended for loose,
slippery road surfaces only. Driving in the 4H and 4L
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
The 4WD indicator light, located in the instrument panel,
alerts the driver that the vehicle is in four wheel drive
and that the front and rear driveshafts are locked to-
gether. This light illuminates when the transfer case is
shifted to either the 4H or 4L positions.
170 STARTING AND OPERATING

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
5

4H Position
Four Wheel Drive High Range Ð Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction for loose,
slippery road surfaces.
N (Neutral) Position
Neutral Ð Disengages both the front and rear driveshafts
from the powertrain. To be used for flat towing behind
another vehicle. Refer to ªRecreational Towingº in Sec-
tion 5 of this manual.
4L Position
Four Wheel Drive Low Range Ð Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction and maxi-
mum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 55 mph (88 km/h). With the
vehicle in motion, the transfer case will engage/
disengage faster if you momentarily release the accelera-
tor pedal after completing the shift. Apply a constant
force when shifting the transfer case lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (Neutral) or depress the
clutch pedal on a manual transmission. While the vehicle
is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE:Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift the auto-
matic transmission to N (Neutral), hold foot on brake,
and turn the engine OFF. Make shift to desired mode.
172 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.

WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear
wheel remaining on the ground and cause you to
lose control of your vehicle.
AXLE LOCK (TRU±LOKŸ) Ð IF EQUIPPED
The Axle Locker switch is located on the lower center of
the instrument panel. This feature will only activate
when the following conditions are met:
²Key in ignition, vehicle in 4L (Low) range.
²The vehicle must be traveling at 10 mph (16 km/h) or
less.
To activate the system, press the switch once to lock the
rear axle only (the REAR LOCK indicator light will
illuminate), press the switch again to lock the front axle
(the FRONT LOCK indicator light will illuminate). Once
the rear axle is locked, pressing the switch again will lock
or unlock the front axle.
NOTE:The indicator lights will flash until the axles are
fully locked or unlocked. A chime will sound three times
and the indicator lights will continue to flash at a
different rate if the key is removed while the axles are still
in the locked position.
To unlock the axles, pull up on the switch.
174 STARTING AND OPERATING

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

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.
