NOTICE:
Do not tow the vehicle from the rear with loads
approaching the rated
GVW as the weight
transfer will cause the front suspension
to
become overloaded.
NOTICE:
Do not tow with the sling-type equipment or the
rear bumper will be damaged. Use wheel lift or
car-carrier equipment. Additional ramping may
be required for car-carrier equipment. Use safety
chains and wheel straps.
Towing
a vehicle over rough surfaces could
damage a vehicle.
To help avoid damage, install a
towing dolly and raise the vehicle until adequate
clearance is obtained between the ground and/or
wheel-lift equipment.

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 “blow out” 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 “blowout,” 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.

If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers.
a CAUl ION:
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.

Downloaded from www.Manualslib.com manuals search engine The ratchet has a DOWN side and an UP side.
Attach the ratchet, with the
DOWN side facing you, to
the extension. The extension has a socket end and
a flat
chisel end.
Put the flat end
of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft. 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.

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.

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.
2. The jack has a bolt on the end. Attach the socket end
of the extension to thejack bolt.
Attach
the ratchet to the extension with the UP side
facing
you.

r
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make the vehicle fall.
To avoid personal injury and
vehicle damage, be sure
to fit the jack lift head into
the proper location before raising your vehicle.
5. Raise the vehicle by rotating 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.

Downloaded from www.Manualslib.com manuals search engine A 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.
A 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 rotating the jack handle
counterclockwise. Lower the jack completely.
