This system is controlled by the electronic control sway bar
switch located below the instrument panel.Sway Bar Disconnect Button
Push the SWAY BAR switch to activate the system. Push the
switch again to deactivate the system. The “Sway Bar Indi -
cator Light” (located in the instrument cluster) will illumi -
nate when the bar is disconnected. The “Sway Bar Indicator
Light” will flash during activation transition, or when activa -
tion conditions are not met. The stabilizer/sway bar should
remain in on-road mode during normal driving conditions. To disconnect the stabilizer/sway bar, shift to either 4HI or
4LO and push the SWAY BAR button to obtain the Off-Road
position. Refer to “Four Wheel Drive Operation” in “Starting
And Operating” for further information. The “Sway Bar
Indicator Light” will flash until the stabilizer/sway bar has
been fully disconnected.
NOTE:
The stabilizer/sway bar may be torque locked due to left and
right suspension height differences. This condition is due to
driving surface differences or vehicle loading. In order for
the Stabilizer/Sway Bar to disconnect/reconnect, the rightWARNING!
Do not disconnect the stabilizer bar and drive on hard
surfaced roads or at speeds above 18 mph (29 km/h), you
may lose control of the vehicle, which could result in
serious injury or death. The front stabilizer bar enhances
vehicle stability and assists in maintaining control of the
vehicle. The system monitors vehicle speed and will
attempt to reconnect the stabilizer bar at speeds over
18 mph (29 km/h). This is indicated by a flashing off road
light and solid on road light. Once vehicle speed is
reduced below 14 mph (22 km/h), the system will
attempt to return to the Off-Road mode.

336 STARTING AND OPERATING
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
• Completely inspect the underbody of your vehicle. Checktires, body structure, steering, suspension, and exhaust
system for damage.
• Inspect the radiator for mud and debris and clean as required.
• Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and suspension.
Retighten them, if required, and torque to the values spec -
ified in the Service Manual.
• Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts. • After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
• If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for impacted
material. Impacted material can cause a wheel imbalance
and freeing the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in
dirty conditions, get your brakes checked and cleaned as
necessary.

Dual Rear Wheel Jack Placement
6. Finish tightening the lug nuts. Push down on the lug wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. For the correct lug nut
torque refer to “Torque Specifications” in “Technical
Specifications”. If in doubt about the correct tightness,
have them checked with a torque wrench by an autho -
rized dealer or service station. 7. Install the wheel center cap and remove the wheel blocks.
Do not install chrome or aluminum wheel center caps on
the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as previously described.
NOTE:
The bottle jack will not lower by turning the dial (thumb -
wheel) by hand, it may be necessary to use the jack driver in
order to lower the jack
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute
with chrome plated lug nuts.
WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

528 SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used. Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis
-
sion Fluid (ATF) is an engineered product and its perfor -
mance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the transmis -
sion. Avoid using transmission sealers as they may
adversely affect seals.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate the brake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.

TECHNICAL SPECIFICATIONS 565
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
Hydraulic Brake Assist — 2500/3500 Models Only
(Except Power Wagon)
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.

6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine. This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number range of 87 to 89 as
specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso -
line with an octane number lower than 87 can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before considering
service for the vehicle.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.8
