Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.
NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment. A towing dolly must be used
under the drive wheels when towing from the front.

Towing Limits
-- 35 mph (56 km/h),
50 miles (80 km)
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.

Engine Fan Noise
Your 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 you may hear an increase in
fan noise. This is normal and should not be mistaken as
the transmission slipping or making extra shifts. It is
merely the cooling system functioning properly. The fan
will slow down when additional cooling is not required
and the clutch partially disengages.
You may also hear this fan noise when you start
the engine. It will go away as the fan clutch
partially disengages.
If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create 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 out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
The following steps will tell you how to use the jack and
change a tire.

Turn the ratchet counterclockwise to lower the spare tire
to the ground. If you are changing a flat rear tire and the
vehicle is already jacked up, use the jack handle and
extension to hook the cable. Then pull the spare from
beneath the vehicle. If the retainer pulls out, hook the
inside of the wheel and pull the spare tire out from under
the vehicle.
When the tire has been lowered, tilt the retainer at the
end of the cable and pull it through the wheel opening.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before the cable is restored.

5-26 Removing the Wheel Covers and Locking
Wheel Nuts
1. You will need to take off the wheel nut caps to reach
your wheel nuts. When using the ratchet and socket,
make sure the DOWN side faces you.
2. Loosen the plastic nut caps.

3. Remove the center cap.
Removing the Flat Tire and Installing the
Spare Tire
1. With the DOWN side facing you, use the ratchet and
socket to loosen all the wheel nuts. Don't remove
them yet.

5. Raise the vehicle by turning the ratchet clockwise.
Make sure the UP mark faces you. 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, and take off the
flat tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.

CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
8. Replace the wheel nuts
with the rounded end of
the nuts toward the
wheel. Tighten each
wheel nut by hand until
the wheel is held against
the hub.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
