Warning (Continued)
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer. See“Driving on
Grades” underTrailer Towing on
page 9-46. If the overheat warning is displayed
with no sign of steam:
1. Turn the air off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the engine coolant temperature
gauge is no longer in the overheat
zone or an overheat warning no
longer displays, the vehicle can be
driven. Continue to drive the vehicle
slowly for about 10 minutes. Keep a
safe vehicle distance from the
vehicle in front. If the warning does
not come back on, continue to drive
normally and have the cooling
system checked for proper fit and
function.
If the warning continues, pull over,
stop, and park the vehicle
right away. If there is still no sign of steam,
push down the accelerator until the
engine speed is about twice as fast
as normal idle speed for at least
three minutes while parked. If the
warning is still on, turn off the
engine until it cools down.
If the decision is made not to lift the
hood, get service help right away.
Engine Fan
The vehicle has a clutched engine
cooling fan. When the clutch is
engaged, the fan spins faster to
provide more air to cool the engine.
In most everyday driving conditions,
the fan is spinning slower and the
clutch is not fully engaged. This
improves fuel economy and reduces
fan noise. Under heavy vehicle
loading, trailer towing, and/or high
outside temperatures, the fan speed
increases as the clutch more fully
engages, so an increase in fan
noise may be heard. This is normal
and should not be mistaken as the
transmission slipping or making

Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on
page 10-51.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12-2.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Dual Tire Rotation
When the vehicle is new,
or whenever a wheel, wheel bolt,
or wheel nut is replaced, check the
wheel nut torque after
160, 1 600, and 10 000 km (100,
1,000, and 6,000 mi) of driving. For
proper wheel nut tightening
information, see “Removing the Flat
Tire and Installing the Spare Tire”
under Tire Changing on page 10-65.
Also see “Wheel Nut Torque” under
Capacities and Specifications on
page 12-2.
The outer tire on a dual wheel setup
generally wears faster than the
inner tire. Tires last longer and wear
more evenly if they are rotated. See
Tire Inspection on page 10-55
and Tire Rotation on page 10-55.
Also see Maintenance Schedule on
page 11-3.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
can lose air suddenly or catch
fire. You or others could be
injured. Properly inflate all tires,
including the spare.
See Tires on page 10-40 andTire
Pressure on page 10-49 for more
information on proper tire inflation.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.

Warning (Continued)
crash. To help avoid damage to
the vehicle, drive slowly, readjust,
or remove the device if it is
contacting the vehicle. Do not
spin the vehicle's tires. Follow the
manufacturer's instructions.
{Caution
Use tire chains only where legal
and only when necessary. Use
chains that are the proper size for
the tires. Install them on the tires
of the rear axle. Do not use
chains on the tires of the front
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues,(Continued)
Caution (Continued)
slow down until it stops. Driving
too fast or spinning the wheels
with chains on will damage the
vehicle.
For Cutaway models with LT245/
75R16, LT225/75R16 or LT215/
85R16 size single or dual rear tires,
use Low Profile Z-Chain or SAE
Class S cables.
For Cargo or Passenger models
with P245/70R17, LT225/75R16 or
LT245/75R16 size tires, use Low
Profile Z-Chain cables. SAE Class S
chains are not recommended.
If the vehicle has dual rear tires, do
not use individual tire chains. Use
tire chains that fit across both dual
tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. See Tires
on page 10-40. If air goes out of a
tire, it is much more likely to leak
out slowly. But if there ever is a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.

in order to avoid any
interference with the exhaust
pipe (2).
{Warning
Getting under a vehicle when it is
jacked up is dangerous. If the
vehicle slips off the jack you could
be badly injured or killed. Never
get under a vehicle when it is
supported only by a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.5. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit.
6. Remove all the wheel nuts.
7. Take the flat tire off of themounting surface.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.

8. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel.
{Warning
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
9. Put the wheel nuts back on withthe rounded end of the nuts
toward the wheel. Tighten each
wheel nut by hand until the
wheel is held against the hub.
10. Turn the jack handle counterclockwise to lower the
vehicle. Lower the jack
completely.
{Warning
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
{Warning
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are
damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in

Storing a Flat or Spare Tire
and Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
1. Put the tire on the ground at the rear of the vehicle with the valve
stem pointed down.2. Pull the retaining bar through thecenter of the wheel, making sure
it is properly attached.
3. Pull the wheel toward the rear of the vehicle, keeping the cable
tight.
4. Open the passenger side rear door.
5. Insert the chisel end of the hoist handle, on an angle, through the
hole in the rear floor panel
above the bumper.
6. Turn the wheel wrench clockwise to fully raise the tire
against the underside of the
vehicle. Continue turning the
wheel wrench until the tire is
secure and the cable is tight. Two clicks should occur. The
spare tire hoist cannot be
overtightened.
7. Make sure the tire is stored
securely. Push, pull (1), and then
try to turn (2) the tire. If the tire
moves, use the wheel wrench to
tighten the cable.
Two clicks mean the tire is up all
the way.
8. Return the jacking equipment to the proper location. Secure the
items and replace the jack cover.

Towing the Vehicle
{Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Have the vehicle towed on a flatbed
car carrier or a wheel lift tow truck.
If a wheel lift tow truck is used, the
drive wheels cannot contact the
road while the vehicle is being
towed. A wheel dolly must be used
to lift all drive wheels off the ground.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle, such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly.
Here are some important things to
consider before recreational vehicle
towing:
.What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations.
.What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.

.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Dinghy Towing
Two-Wheel-Drive Vehicles
{Caution
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not
be covered by the vehicle
warranty. Do not tow the vehicle
with all four wheels on the
ground.
The vehicle should not be towed
with all four wheels on the ground.
Dolly Towing
Rear Towing (Rear Wheels Off the
Ground)
Use the following procedure to tow
the vehicle from the rear:
1. Attach the dolly to the tow vehicle following the dolly
manufacturer's instructions.
2. Drive the rear wheels onto the dolly.
3. Firmly set the parking brake. See Parking Brake on
page 9-29.
