WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to

the hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL. Always,
block or \bchock\bthe trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW

Recreational Towing — Rear-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe 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 apply the parking brake. Shift the transmission into PARK. 4. Turn the ignition switch to the OFF position.
5. Properly secure the rear wheels to the dolly, following
the dolly manufacturer ’s instructions.
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.
588 STARTING AND OPERATING

WARNING!(Continued)
•Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set the automatic
transmission in PARK.
• 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. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
(Continued)
WARNING! (Continued)
•To assure that spare tires, flat or inflated, are

WHAT TO DO IN EMERGENCIES 609

NOTE:Double check to ensure the tire is snug against the
underbody of the vehicle. Damage to the winch cable
may result if the vehicle is driven with the tire loose.
WARNING!
Do not use power tools to winch the tire up or down.
Impact-type tools may damage the winch mecha-
nism.
13. Lower the jack to the fully closed position. Return the tools to the proper positions in the tool bag. Fold the
flap on the tool bag under the tools and roll the tools
in the bag underneath the others. Use the Velcro
straps to secure the tool bag to the jack with the lug
wrench on the forward side of the jack. Expand the
jack on the bracket by turning the thumb screw
clockwise until it is tight to prevent rattles.
14. Reinstall the plastic plug into the floor of the cargo area. Roll up and store the Jack, Tool Kit and Tire
Changing Instructions. Reinstall the cover for the jack
in the rear storage bin.

15. Have the aluminum road wheel and tire repaired assoon as possible and properly secure the spare tire,
jack and tool kit.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shapedend of the nut toward the wheel. Lightly tighten the
lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Refer to Torque Specifications for proper lug nut torque.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that all lug nuts are properly
seated against the wheel.
616 WHAT TO DO IN EMERGENCIES

WARNING!
•Do not use a chain for freeing a stuck vehicle.
Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged, caus-
ing serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
Release. Activating the Manual Park Release will
allow your vehicle to roll away if it is not secured by
the parking brake or by proper connection to a tow
vehicle. Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury or
death for those in or around the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery),
a Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.

WHAT TO DO IN EMERGENCIES 625

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the key fob is unavailable or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Rear Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) with the transmission in NEU-
TRAL. Speed must not exceed 30 mph (48 km/h) and the
distance must not exceed 30 miles (48 km).
CAUTION!
Towing faster than 30 mph (48 km/h) or farther than
30 miles (48 km) with rear wheels on the ground can
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
