ROCK-TRAC™
• The transfer case provides four modepositions: 2H (Two-wheel drive high
range), 4H (Four-wheel drive high
range), N (Neutral), and 4L (Four-wheel
drive low range).
• The transfer case is intended to be driven in the 2H position for normal
street and highway conditions such as
hard-surfaced roads.
• Shifting between 2H and 4H can be made with the vehicle stopped or in
motion. Shift the transfer case lever
firmly to 4H at any speed up to 50 mph
(80 km/h).
• Shifting between 4H and 4L can be made with the vehicle rolling at 2 to
3 mph (3 to 5 km/h), shift the automatic
transmission in NEUTRAL or fully
depress the clutch pedal on a manual
transmission. Shift the transfer case
lever firmly to 4L (do not pause with the
transfer case in NEUTRAL).
NOTE: To enhance off-road
performance in 4L mode, manual
transmission vehicles will start
regardless of whether or not the clutch
pedal is depressed.

RECREATIONAL TOWING
(BEHIND MOTORHOME)
Towing - Two-Wheel Drive
Models
• Recreational towing with all fourwheels on the ground is allowed ONLY
if the rear driveshaft is removed. See
your authorized dealer or refer to the
Service Manual. Towing with the rear
wheels on the ground while the
driveshaft is connected can result in
severe transmission damage.
WARNING!
If the driveshaft is removed, the
vehicle can roll even if the
transmission is in PARK, which could
cause serious injury or death.
• The parking brake must be firmly engaged and the wheels chocked
during driveshaft removal and
installation. The parking brake must
remain engaged unless the vehicle is
securely and properly connected to the
tow vehicle, or the driveshaft is
completely reinstalled. See your
authorized dealer for proper driveshaft
removal and reinstallation procedures,
including flange orientation/alignment,
use of thread-locking compound,
proper bolt torque specifications, etc.
Towing - Four-Wheel Drive

Preparations For Jacking
• Park on a firm, level surface. Avoid ice or slippery areas.
• Set the parking brake and shift the automatic transmission into PARK, or a manualtransmission into REVERSE.
• Turn the ignition to LOCK and turn on the Hazard Warning flasher. • Block both the front and rear of the wheeldiagonally opposite of the jacking position.
For example, if changing the right front tire,
block the left rear wheel.
NOTE: Passengers should not remain in the
vehicle when the vehicle is being jacked.
Jacking And Tire Changing Instructions
WARNING!
Carefully follow these tire changing procedures to help prevent personal injury or
damage to your vehicle: Always park on a firm, level surface as far from the edge of
the roadway as possible before raising the vehicle.
• Remove the spare tire, jack and tools from the stored location.
• Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground.
• Assemble the jack and jacking tools. Connect the jack handle driver to the extension, then to the lug wrench.
• Operate the jack from the front or the rear of the vehicle. Place the jack under the axle tube. Do not raise the vehicle until you are sure the jack is fully engaged.
WHAT TO DO IN EMERGENCIES

WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can startanytime the ignition switch is on. You can be injured by moving fan blades.
• Remove any metal jewelry such as watch bands or bracelets that might make an inadvertent electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• If using a another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in personal injury or property damage
due to battery explosion.
CAUTION!
Failure to follow these procedures could result in damage to the charging system of
the booster vehicle or the discharged vehicle.
• Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged vehicle.
• Connect the opposite end of the positive (+) jumper cable to the positive (+) post of the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery.
• Connect the opposite end of the negative (-) jumper cable to a good engine ground (exposed metal part of the discharged vehicle’s engine) away from the battery and the
fuel injection system.
