Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLY if the rear wheels are OFF the ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly set the parking brake. Place automatic transmis-
sion in PARK, manual transmission in gear (not in Neutral).
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Remove the key fob from the ignition switch.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position. CAUTION!• Towing with the rear wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
• Do not disconnect the driveshaft because fluid
will leak from the transmission, causing damage
to internal parts.
Recreational Towing – Four-Wheel Drive Models
NOTE: Both the manual shift and electronic shift trans-
fer cases must be shifted into NEUTRAL for recreational
towing. Automatic transmissions must be shifted into
PARK for recreational towing. Manual transmissions
must be placed in gear (NOT in NEUTRAL) for recre-
ational towing. Refer to the following for the proper
transfer case NEUTRAL shifting procedure for your
vehicle. 5 STARTING AND OPERATING 345

WARNING! (Continued)• Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
(Continued) WARNING! (Continued)• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
1. If equipped, remove the spare wheel, jack, and tools
from storage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground. Jack Warning Label

3. When changing the front wheel, assemble the jack
drive tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle as close to
the tire as possible with the drive tubes extending to the
front. Connect the jack tube extension and wheel wrench. When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Securely place the jack under the sway
bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing forward in vehicle.
Connect the jack tube extension and lug wrench.

WARNING!• Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also labeled on the origi-
nal factory installed hydraulic master cylinder
reservoir.
(Continued) WARNING! (Continued)• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a accident.
• 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.
