(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)
Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires–General Information” in this section for infor-
mation on tire pressures and for proper tire inflation
procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires–General Infor-
mation” in this section for information on tread wear
indicators and for the proper inspection procedure.
When replacing tires, refer to “Tires–General Informa-
tion” in this section for information on replacement
tires and for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity
will not increase the vehicle’s GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
356 STARTING AND OPERATING

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the pointer drops back into the normal range 200–
230°F (93–110°C). If the pointer remains at 240°F
(116°C) or greater and you hear a chime, turn the
engine off immediately and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7 and follow the
warnings under the Cooling System Pressure Cap
paragraph.
TIREFIT TIRE REPAIR
Small punctures, particularly those in the tread, can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).

and forth approximately 30 ft (9.1 m) to distribute the
sealant more evenly within the tire.
12. Turn on the hazard warning flashers.13. Move the shift lever to the PARK position, turn off
the engine, and set the parking brake.
14. Disconnect the air pump hose (1) from the underside
of the sealant bottle (5) by flipping the hose valve open.
15. Connect the air pump hose valve to the tire valve and
flip the hose valve closed.
16. Leave the parking brake set and the shift lever in
PARK and start the engine.
17. Press the switch (3) on the air pump to I (ON). The air
pump should inflate the tire to at least 26 psi (1.8 bar)
within five minutes. If the tire inflates to this level,
proceed to the following step.NOTE:If a tire pressure of
26 psi (1.8 bar) is not obtained within five minutes, the
tire is too badly damaged. Do not attempt to drive the
vehicle further. Call for assistance.

Close the load floor cover. Replace the sealant bottle at
your nearest authorized MOPARparts dealership.
29. Have the tire inspected at the earliest opportunity at
an authorized dealer or tire service center.
NOTE:
•If a pressure of at least 19 psi (1.3 bar) cannot be
maintained in the tire, the tire is too badly damaged.
Do not attempt to drive the vehicle further. Call for
assistance.
•Do not operate the electric air pump for more than
eight minutes to avoid overheating. The air pump may
be used again once it has cooled down.
•Replace the TIREFIT sealant bottle (5) once every four
years to assure optimum operation of the system.
•If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material has dried,
it can easily be peeled off and properly discarded.
•Do not exceed 55 mph (90 km/h) until the tire has
been inspected.
370 WHAT TO DO IN EMERGENCIES

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between RE-
VERSE and DRIVE. Usually, the least accelerator pedal
pressure to maintain the rocking motion without spin-
ning the wheels is most effective.
NOTE:Turn off the Electronic Stability Program (ESP)
before rocking the vehicle. Refer to “Electronic Stability
Program,” or “Traction Control” in Section 5.CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween “1st” and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.
•Racing the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 35 mph (55 km/h).
374 WHAT TO DO IN EMERGENCIES

Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed, and refilled with
fresh coolant. Check the front of the A/C condenser for
any accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts, and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin todrain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the
intervals shown in the “Maintenance Schedule” in Sec-
tion 8.
If the solution is dirty or contains a considerable amount
of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze solution.
Selection of Coolant
Use only the manufacturer’s recommended coolant. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct coolant type.
398 MAINTAINING YOUR VEHICLE
