The Tire Pressure Monitoring Telltale Lamp will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. The audible
chime will sound once every ignition cycle for each
condition that it detects. Should this occur, you should
stop as soon as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to the
pressure recommended by the vehicle manufacturer. The
system will automatically update and the TPM warning
lamp will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 10 minutes above 15 mph (25 kph) to receive
this information.
A low spare tire will not cause the Tire Pressure Moni-
toring Telltale Lamp to illuminate or the chime to sound.
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 60 seconds, and an audible chime will soundwhen a system fault is detected. The flash cycle will
repeat every ten minutes, without an audible chime, until
the fault condition no longer exists. If the ignition key is
cycled, this sequence will repeat, providing the system
fault still exists.
NOTE:A non-matching or compact spare wheel and
tire assembly does not have a tire pressure monitoring
sensor; therefore, it will not be monitored by the Tire
Pressure Monitor System (TPMS). If the non-matching or
compact spare tire was used in place of one of the four
road tires, a system fault will occur while driving the
vehicle. In case of a low pressure condition (ie. flat tire),
the “Tire Pressure Monitoring Telltale Light” will remain
on solid until the original road tire has been properly
repaired, and put back onto the vehicle in place of the
non-matching or compact spare tire.

•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or 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 automatic transmission in
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block orchockthe 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. GVWR2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized
(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 the
Tires–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.

JACKING INSTRUCTIONS
Removing The Spare Tire
The spare tire on your vehicle is located underneath the
vehicle in the rear.
Remove the spare tire before attempting to jack the truck.1. Remove the rubber plug from the floor in the cargo
area.
2. Engage the jack wrench extension to the spare tire
winch through the hole in the floor.
3. Turn the wrench counterclockwise to lower the spare
tire. Continue to turn the wrench until the spare tire can
be pulled out from under the vehicle.
348 WHAT TO DO IN EMERGENCIES

It is recommended that you stow the flat or spare to
avoid tangling the loose cable.
CAUTION!
The winch mechanism is designed for use with the
jack extension tube only. Use of an air wrench or
other power tools is not recommended and can
damage the winch.
Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle 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.
Do not raise this vehicle using a bumper jack. The scissor
jack is designed as a tool for changing tires on this vehicle
only. It is not recommended that the jack be used for
service purposes or to lift more than one wheel at a time.

Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission). On Four
Wheel Drive vehicles, shift the transfer case to the “4L”
position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Instructions
1. 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.
350 WHAT TO DO IN EMERGENCIES

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.
4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. Lightly tighten the nuts. To
avoid risk of forcing the vehicle off the jack, do not fully
tighten the nuts until the vehicle has been lowered.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
6. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 135 ± 10 ft.
lbs. (183 ± 14 N·m) dynamic torque. If in doubt about the
correct tightness, have them checked with a torque
wrench by your dealer or at a service station.

WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack, tools and the extra tire and
wheel in the places provided.
7. Remove wheel blocks. Do not install chrome or alu-
minum wheel center caps on the spare wheel. This may
result in cap damage.
8. Lower the jack to its fully closed position. Stow the
replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
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.
•Block the wheel diagonally opposite the wheel to be
raised.
•Apply the parking brake firmly before jacking.
•Never start 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.
•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 value stem
facing the ground.
