1996 CHEVROLET BLAZER traction control

Downloaded from www.Manualslib.com manuals search engine If you skip more than onc ,ear when you
downshift, you could lose control of your vehicle. And you could injure yourself or others. Don’t shift
down more than one gear when you downshift.
If your vehicle has four-wheel drive and is equipped
with a manual transmission, disregard the shift light
when the transfer case is in
4LO.
Locking Rear Axle
If you have this reature, your rear axle can give you
additional traction
on snow, mud, ice, sand or gravel. It
works like a standard axle most
of the time, but when
one of the rear wheels has no traction and the other does,
the locking feature will allow the wheel with traction to
move the vehicle.
All-Wheel Drive (Option)
If your vehicle has all-wheel drive, your engine’s
driving power is
sent to all four wheels for extra
traction. This
is like four-wheel drive, but there is no
lever or switch to engage or disengage the front
axle.
It is fully automatic and adjusts itself as needed for
road conditions.
Four-wheel Drive (Option)
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction.
To shift out of two-wheel drive and into
four-wheel drive, move the transfer case shift lever
to
4HI or 4LO. You should use 2HI for most normal
driving conditions.
NOTICE:
Driving in the 4HI or 4LO positions for a long
time on dry or wet pavement could shorten the life of your vehicle’s drivetrain.

Downloaded from www.Manualslib.com manuals search engine To shift into or out of 4LO:
1. The vehicle must be moving less than 3 mph
(4.8 kmrdh) with the transmission in NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method for shifting into or
out of
4LO is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 kdh).
2. Press the transfer case shift button and shift in one
continuous motion.
Don’t pause
in N SET PARK BRAKE as you shift into
or out
of 4L0, or your gears could clash.
Remember that driving in
4HI or 4LO may reduce
fuel economy.
Also, driving in four-wheel drive on
dry.pavement could cause your tires to wear faster and
make your transfer case harder
to shift and reduce
powertrain longevity.
Electronic Transfer Case (Option)
If your four-wheel-drive
vehicle has the electronic
transfer case, the transfer
case switches are above
the radio controls.
Use these switches to shift into and out of four-wheel
drive. You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is
not engaged in
two-wheel drive.
4HI: This setting engages your front axle to help
drive your vehicle.
Use 4HI when you need extra
traction, such as on snowy or icy roads, or
in most
off-road situations.

With cruise control, you can
maintain a speed
of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does
not
work at speeds below about
25 mph (40 kdh).
If
you have an automatic transmission and you apply
your brakes, the cruise control will
shut off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will
shut off.

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t change the time you need
to get your foot up
to the brake pedal or always decrease
stopping distance. If
you get too close to the vehicle in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though
you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may feel the brakes
vibrate, or
you may notice some noise, but this is normal.
On vehicles with four-wheel drive, your anti-lock brakes
work at all times
-- whether you are in two-wheel drive
or four-wheel
drive.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen
on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws
of physics when driving on curves. The
traction
of the tires against the road surface makes it
possible
for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep
the vehicle going
in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, yodll understand this.
The traction you can get in a curve depends on the
condition
of your tires and the road surface, the angle at
which the curve
is banked, and your speed. While you’re
in
a curve, speed is the one factor you can control.

Downloaded from www.Manualslib.com manuals search engine Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet
the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to
steer and constantly seek
an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”
those conditions. But skids are always possible.
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.

Downloaded from www.Manualslib.com manuals search engine Controlling your vehicle is the key to successful
off-road driving. One of
the best ways to control your

you’ll need more distance
for braking, especially
since you’re on an unpaved surface.
When you’re driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash.
So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.
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.
Surjizce Conditions. 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.
Sutfkce 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?
0 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?

Downloaded from www.Manualslib.com manuals search engine 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, €or 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.
I
Driving on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces ‘only.

Downloaded from www.Manualslib.com manuals search engine Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires
of different sizes may also cause
damage to your vehicle. Be sure
to use the same
size and type tires
on all wheels.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold
in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production tires. While the tires
available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may have
poor traction performance.
