1995 CHEVROLET SUBURBAN change wheel

The three types of skids correspond to your vehicle’s three control systems.
In the braking skid your wheels aren’t rolling. In the steering or cornering
skid, too much speed or steering
in a curve causes tires to slip and lose
cornering force. And in the acceleration skid too much throttle causes the
driving wheels to spin.
A cornering skid and an acceleration skid are best handled by easing your
foot off the accelerator pedal.
If your vehicle starts
to slide, ease your foot off the accelerator pedal and
quickly steer the way you want the vehicle to go. If
you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice, gravel, or other
material is on the road. For safety,
you’ll want to slow down and adjust your
driving to these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and vehicle control more
limited.
While driving
on a surface with reduced traction, try your best to avoid
sudden steering, acceleration, or braking (including engine braking by
shifting
to a lower gear). Any sudden changes could cause the tires to slide.
You may
not realize the surface is slippery until your vehicle is skidding.
Learn to recognize warning clues
- such as enough water, ice or packed
snow
on the road to make a “mirrored surface” - and slow down when you
have any doubt.
Remember: Any anti-lock brake system (ABS) helps avoid
only the braking
skid.
Driving Guidelines
This multipurpose passenger vehicle is defined as a utility vehicle in
Consumer Information Regulations issued by the National Highway Traffic
Safety Administration (NHTSA)
of the United States Department of
Transportation. Utility vehicles have higher ground clearance and a
narrower track to make them capable
of performing in a wide variety of
off-road applications. Specific design characteristics give them a higher
center of gravity than ordinary cars. An advantage of the higher ground
clearance is a better view
of the road allowing you to anticipate problems.
They are
not designed for cornering at the same speeds as conventional
2-wheel drive vehicles any more than low-slung sports cars are designed
to
perform satisfactorily under off-road conditions. If at all possible, avoid
sharp turns or abrupt maneuvers. As with other vehicles of this type, failure
to operate this vehicle correctly may result
in loss of control or vehicle
rollover.

Controlling your vehicle is the key to successful off-road driving. One of
the best ways to control your vehicle is to control your speed. Here are some
things to keep
in mind. At higher speeds:
you approach things faster and you have less time to scan the terrain for
obstacles.
you have less time to react.
you have more vehicle bounce when you drive over obstacles.
you’ll need more distance for braking, especially since you’re on an
unpaved surface.
Scanning the Terrain
Off-road driving can take you over many different kinds of terrain. You
need to be familiar with the terrain and its many different features. Here are
some things to consider.
Surface Cunditiuns. Off-roading can take you over hard-packed dirt,
gravel, rocks, grass, sand, mud, snow or ice. Each
of these surfaces affects
the steering, acceleration, and braking of your vehicle in different ways.
Depending upon the kind
of surface you are on, you may experience
slipping, sliding,
wheel spinning, delayed acceleration, poor traction, and
longer braking distances.
Surface Obstacles . Unseen or hidden obstacles can be hazardous. A rock,
log, hole, rut, or bump can startle you if you’re not prepared for them. Often
these obstacles are hidden by grass, bushes, snow or even the rise and fall
of
the terrain itself. Here are some things to consider:
Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill? (There’s more discussion
of these subjects later.)
0 Will you have to stop suddenly or change direction quickly?
When you drive over obstacles or rough terrain, keep a firm grip
on the
steering wheel. Ruts, troughs, or other surface features can jerk the wheel
out
of your hands if you’re not prepared.

When you drive over bumps, rocks, or other obstacles, your wheels can
leave the ground.
If this happens, even with one or two wheels, you can’t
control the vehicle as well or at all.
Because you will be on an unpaved surface, it’s especially important to
avoid sudden acceleration, sudden turns, or sudden braking.
In a way, off-road driving requires a different kind of alertness from driving
on paved roads and highways. There are no road signs, posted speed limits
or signal lights. You have to use your own good judgment about what is safe
and what isn’t.
Drinking and driving can be very dangerous on any road. And this is
certainly
true for off-road driving. At the very time you need special
alertness and driving skills, your reflexes, perceptions and judgment can be
affected by even
a small amount of alcohol. You could have a serious - or
even fatal
- accident if you drink and drive or ride with a driver who has
been drinking. (See “Drunken Driving” in the Index.)
Driving On Off-Road Hills
Off-road driving often takes you up, down, or across a hill. Driving safely
on hills requires good judgment and an understanding of what your vehicle
can and can’t do. There are some hills that simply can’t be driven, no matter
how well built the vehicle.
Approaching a Hill
When you approach a hill, you need to decide if it’s one of those hills that’s
just too steep to climb, descend, or cross. Steepness can be hard to judge.
On a very small hill, for example, there may be a smooth, constant incline
with only
a small change in elevation where you can easily see all the way
to the top. On a large hill, the incline may get steeper as you near the top,
but you may not see this because the crest of the hill is hidden by bushes,
grass, or shrubs.

Driving In Mud, Sand, Snow, Or Ice
When you drive in mud, snow or sand, your wheels won’t get good traction.
You can’t accelerate as quickly, turning is more difficult, and you’ll need
longer braking distances.
It’s best to
use a low gear when you’re in mud - the deeper the mud, the
lower the gear.
In really deep mud, the idea is to keep your vehicle moving
so you don’t get stuck.
When you drive on sand, you’ll sense a change in wheel traction. But it will
depend upon how loosely packed the sand is. On loosely packed sand (as on
beaches or sand dunes) your tires will tend to sink into the sand.
This has an
effect on steering, accelerating, and braking.
You may want to reduce the air
pressure in your tires slightly when driving
on sand. This will improve
traction.
Hard packed snow and ice offer the worst tire traction. On these surfaces,
it’s very easy to lose control. On wet ice, for example, the traction is
so poor
that you will have difficulty accelerating. And if you do get moving, poor
steering and difficult braking can cause
you to slide out of control.

To wing Your Vehicle
Try to have your 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 since it was factory-new, by adding such
things 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:
0 That your vehicle has rear-wheel drive, or that it has the four-wheel
drive option.
The make, model, and year of your vehicle.
0 Whether you can move the shift lever for the transmission and transfer
case, if you have one.
0 If there was an accident, what was damaged.
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 and transfer case, if you have one,
should be in NEUTRAL (N) and the parking brake released.

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 every day
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, 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.
