1997 CHEVROLET TAHOE brake

Downloaded from www.Manualslib.com manuals search engine Suppose you’re steering through a sharp curve.
Then you suddenly accelerate. Both control
systems
-- steering and acceleration -- have to do their
work where the tires meet the road. Adding the sudden
acceleration can demand too much of those places. You
can
lose control.
What should you do if
this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to
go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed
so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out
of the curve, and then
accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and find a truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front
of you. You can avoid these
problems by braking
-- if you can stop in time. But
sometimes you can’t; there isn’t room. That’s the time \
for
evasive action
-- steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. (See “Braking in
Emergencies’’ earlier in this section.) It is better to
remove as much speed
as you can from a possible
collision. Then steer around the problem, to the left or
right depending on the space available.

Check your mirrors, glance over your shoulder and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that if
your right outside mirror is convex, the vehicle you
just passed may seem to be farther away from you
than it really is.)
Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle
too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting
to turn.
If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.
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.
4-13

Downloaded from www.Manualslib.com manuals search engine 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 defied as a utility
vehicle in Consumer Information Regulations issued by
the National Highway Trafpc 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
two-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.
Off-Road Driving with Your
Four-Wheel-Drive Vehicle
This off-road guide is for vehicles that have
four-wheel drive.
Also, see “Anti-Lock Brakes”
in the Index.
If your vehicle doesn’t have four-wheel drive, you
shouldn’t drive off-road unless you’re on
a level,
solid surface.
Off-road driving can
be great fun. But it does have some
definite hazards. The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North
American road system behind. Traffic lanes aren’t
marked. Curves aren’t banked. There are no road signs.
Surfaces can be slippery, rough, uphill or downhill. In
short, you’ve gone right back to nature.
Off-road driving involves some new skills.
And that’s
why it’s very important that you read this guide. You’ll
find many driving tips
and suggestions. These will help
make your off-road driving safer and more enjoyable.

to stall, and
I can’t make it up the hill?
A: If this happens, there are some things you should

do, and there are some things you must not do.
First, here’s what you
should do:
Push the brake pedal
to stop the vehicle and keep it
from rolling backwards. Also, apply the parking brake.
If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and slowly back down
the hill in REVERSE (R).
If your engine has stopped running, you’ll need to
restart it. With the brake pedal depressed and the
parking brake still applied, shift the transmission to
PARK (P) and restart the engine. Then, shift to
REVERSE
(R), release the parking brake, and
slowly back down the hill as straight as possible in
REVERSE (R).
As you are backing down the hill, put your left hand
on the steering wheel at the
12 o’clock position. This
way, you’ll be able to tell
if your wheels are straight
and maneuver as
you back down. It’s best that you
back down the hill with your wheels straight rather
than in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of a rollover.
Here are some things you
must not do if you stall, or are
about to stall, when going up a hill.
Never attempt to prevent a stall by shifting into
NEUTRAL (N) to “rev-up” the engine and regain
forward momentum. This won’t work. Your vehicle
will roll backwards very quickly and you could go
out of control.
Instead, apply the regular brake to stop the
vehicle. Then apply the parking brake. Shift to
REVERSE
(R), release the parking brake, and
slowly back straight down.
0 Never attempt to turn around if you are about to stall
when going up a hill. If the hill is steep enough to
stall your vehicle, it’s steep enough to cause you to
roll over if you turn around. If you can’t make it up
the hill, you must back straight down the hill.

Downloaded from www.Manualslib.com manuals search engine @ Suppose, after stalling, I try to back down the
hill and decide
I just can’t do it. What should
I do?
A: Set the parking brake, put your transmission in
PARK (P) and turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill
side and stay clear of the path the vehicle would
take if it rolled downhill.
Do not shift the transfer
case to
NEUTRAL (N) when you leave the vehicle.
Leave it in some gear.
A CAUTIG1.I:
- I
Shifting the transfer case to NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is in PARK
(P). This is because the
NEUTRAL
(N) position on the transfer case
overrides the transmission.
If you are going to
leave your vehicle, set the parking brake and
shift the transmission to PARK
(P). But do not
shift the transfer case to the NEUTRAL
(N)
position. Leave the transfer case in the 2 Wheel, 4
High or 4 Low position.

When off-roading takes you downhill, you’ll want to
consider
a number of things:
0 How steep is the downhill? Will I be able to maintain
vehicle control?
0 What’s the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
0 What’s at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large rocks?
If you decide you can go down a
hill safely, then try to
keep your vehicle headed straight down, and use a low
gear. This way, engine drag can help your brakes and
they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.

A C UTT3N:

Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could cause loss
of control and a serious accident.
Apply the brakes lightly when descending a
hill and use a low gear to keep vehicle speed
under control.

When driving downhill, avoid turns that take
you
across the incline of the hill. A hill that’s not too
steep to drive down may

You could roll over if you don’t drive straight down.
Never
go downhill with the transmission in

it happens going downhill, here’s what
to do.

Downloaded from www.Manualslib.com manuals search engine 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. through.
Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly. At
fast speeds, water splashes on your ignition system and
your vehicle can stall. Stalling can
also occur if you get
your tailpipe under water. And, as long as your tailpipe
is
under water, you’ll never be able to start your engine.
When you
go through water, remember that when your
brakes get wet, it may take you longer to stop.

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.
Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t
try it -- you probably won’t get
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.
