Downloaded from www.Manualslib.com manuals search engine Towing Your Vehicle
Try to have a GM dealer or a professional towing service tow your vehicle.
They can provide the right equipment and know how to tow it without
damage.
If your vehicle has been changed or modified since it was factory-new by
adding aftermarket items like fog lamps, aero skirting, or special tires and
wheels, these things could be damaged during towing.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:
That, if your vehicle has all-wheel drive or rear-wheel drive with fog
lamps, it cannot be towed from the front with sling-type equipment.
That your vehicle has rear-wheel drive, or that it has the all-wheel-drive
option.
The make, model, and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
* To help avoid injury to you or others:
I
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
Always use separate safety chains on each side when towing a
truck.
I vehicle.
When your vehicle is being towed, have the ignition key
off. The steering
wheel should be clamped in a straight-ahead position, with a clamping device
designed
for towing service. Do not use the vehicle’s steering column lock for
this. The transmission should be in
N (Neutral) and the parking brake
released.
If your vehicle has the all-wheel drive option, it can only be towed with
all four wheels
off the ground. A dolly must be used under the un-raised
wheels when towing or the vehicle must be transported
on a flat bed
carrier.

Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged,
the fan spins faster
to provide more air to cool the engine. In most every day
driving conditions, the clutch is not engaged. This improves fu\
el economy and
reduces fan noise. Under heavy vehicle loading, trailer towing \
andlor high
outside temperatures, the fan speed increases when the clutch e\
ngages.
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 whe\
n additional
cooling is not required and the clutch disengages.
You may also hear this fan noise when you start the engine.
It will go away
as the fan clutch disengages.
If a Tim 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, 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 co\
ntrol 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 your 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.
I CAUTION
4
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 P (Park).
3. Turn off the engine.
To be even more certain the vehicle won’t move, you can put chocks
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.

You have two wheel blocks stored with your jack. Place blocks at the front

of the tire farthest away from the one being changed. That would

Put your spare tire near the flat tire. Remove the wheel trim.

If there is a wheel cover, remove it by using the flat end of the extension.
Pry along the edge of the wheel cover until it comes off. Be careful; the rim
edges may be sharp. Don't
try to remove it with your bare hands.

To make your tires last longer, have them inspected and rotated a\
t the
mileages recommended in the Maintenance Schedule. See “Scheduled
Maintenance Services” in the Index.
Use this rotation pattern.
If your vehicle has front tires with different load ratings or tread designs (such
as all season vs. on/off road) than the rear tires, don’t \
rotate your tires front
to rear.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the CertificationRire label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
