420 STARTING AND OPERATING
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact sparetire.
• Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
• Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires” in
“Servicing And Maintenance” for proper tire inflation
procedures.
• 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” in “Servicing And Main -
tenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And Maintenance” 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
• Do
not interconnect 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 actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic brake
controller is not required.

• Trailer brakes are recommended for trailers over 1,000 lbs (453 kg) and required for trailers in excess of 2,000 lbs (907 kg).

WARNING!
• Do not connect trailer brakes to your vehicle's hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an accident.

Jacking Instructions
Jack Warning Label
WARNING!
Carefully follow these tire changing warnings 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.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Apply the parking brake firmly and set the transmis -
sion 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.• To assure that spare tires, flat or inflated, are securelystowed, spares must be stowed with the valve stem
facing the ground.

IN CASE OF EMERGENCY 481
NOTE:
If 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.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.
5. Remove the lug nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install the spare wheel and lug
nuts with the cone shaped end of the wheel nuts toward
the wheel. On 3500 dual rear-wheel models (DRW)
trucks, if the outer tire is being replaced then leave the
inner wheel on the vehicle. If the inner wheel is being replaced remove the outer wheel and replace the inner
wheel. The wheel nuts are a two-piece assembly with a
flat face. Lightly tighten the lug nuts. To avoid the risk of
forcing the vehicle off the jack, do not fully tighten the lug
nuts until the vehicle has been lowered.
Rear Inner Wheel Proper Placement (Dual Rear Wheel Equipped)
CAUTION!
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.6

IN CASE OF EMERGENCY 483
To Stow The Flat Or Spare
NOTE:
Have the flat tire repaired or replaced immediately.1. Turn the wheel so that the valve stem is facing the ground
and toward the rear of the vehicle for convenience in
checking the spare tire inflation. Slide the wheel retainer
through the center of the wheel.
Reinstalling The Retainer
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. Have the deflated (flat) tire repaired or
replaced immediately.

IN CASE OF EMERGENCY 495
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.
NOTE:
Vehicles equipped with the Air Suspension System must be
placed in Transport mode, before tying them down (from the
body) on a trailer or flatbed truck. If the vehicle cannot be
placed in Transport mode (for example, engine will not run),
tie-downs must be fastened to the axles (not to the body).
Failure to follow these instructions may cause fault codes to
be set and/or cause loss of proper tie-down tension.
Refer to "Air Suspension System — If Equipped" in "Starting
And Operating" for more information.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating and failure. Allow the engine
to idle with the transmission in NEUTRAL for at least
one minute after every five rocking-motion cycles. This
will minimize overheating and reduce the risk of trans -
mission failure during prolonged efforts to free a stuck
vehicle.
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving 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 30 mph
(48 km/h) while in gear (no transmission shifting occur -
ring).
