Downloaded from www.Manualslib.com manuals search engine Engine Fan Noise
This 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 every day driving
conditions, the clutch is
not engaged. This improves
fuel economy and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or high outside
temperatures, the’ fan speed increases when
the clutch
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 disengages.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch 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.

Downloaded from www.Manualslib.com manuals search engine 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.
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 an automatic transmission shift lever in
PARK (P) or shift
a manual transmission to
FIRST (1)
or REVERSE (R).
3. If you have a four-wheel-drive vehicle
with
a manual transfer case shift lever,
be sure the transfer case is in
a drive
gear
-- not in NEUTRAL (N).
CAUTION: (Continued) CAUTION: (Continued)
4. Turn off the
engine.
5. Put the wheel 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.

Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can
help you get out when you’re stuck, but
you must use caution.
A CAUTION:
If you let your tires spin at high speed, thej In
explode, and you or others could be injured. And,
the transmission or other parts of the vehicle
can overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 kmh) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.

Downloaded from www.Manualslib.com manuals search engine Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around
your front wheels. Then shift back
and forth between REVERSE (R) and a forward gear (or
with a manual transmission, between FIRST
(1) or
SECOND (2) and REVERSE(R)), spinning the wheels
as little as possible. Release the accelerator pedal while
you shift, and press lightly on the accelerator pedal
when the transmission is in gear.
If that doesn’t get you
out after a few tries, you may need to be towed out. Or,
you can use your recovery hooks if your vehicle has
them. If you do need
to be towed out, see “Towing Your
Vehicle” in the Index.
Using the Recovery Hooks
.“ .
Your vehicle may be equipped with recovery hooks.
The recovery hooks are provided at the front of your
vehicle.
You may need to use them if you’re stuck
off-road and need
to be pulled to some place where
you can continue driving.

When to Check and Change
A good time to check your automatic transmission fluid
level
is when the engine oil is changed.
Change both
the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter
do not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).

Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F ( 10°C), drive the
vehicle in
DRIVE (D) until the engine temperature gage
moves and
then remains steady for 10 minutes. Then
follow the
hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10°C) or
more. If it's colder than 50°F (lO"C), you may have to
idle the engine longer. Should
the fluid level be low
during a cold check, you
must perform a hot check
before adding fluid. This will give you
a more accurate
reading
of the fluid level.

then
pull it back out again,
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all
the way; then flip the handle
down
to lock the dipstick in place.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as
a reference.) If
the fluid level is low, add only enough
of the proper
fluid to bring the level up
to the HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint. Don ’t overfill. We recommend you use only fluid
labeled DEXR0N’-111, because fluid with that label is
made especially
for your automatic transmission.
Damage caused by fluid other than DEXRON@-I11 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.

, Too much or too little fluid can dafnage your
l transmission. Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting
a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission is
cool enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. , If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid as described in
the next steps.
