1998 GMC ENVOY stop start

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay
on
for several seconds.
That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is
also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the
red area, your engine is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions,
you should pull off the road, stop your
vehicle and turn off
the engine as soon as possible.
The “Problems on the Road” section
of this manual
shows you what to do. See “Engine Overheating”
in
the Index.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon
as it is possible.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If
the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following.
If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put
fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed.
A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.

And, of course, actual stopping distances vary greatly
with the surface of the road (whether it‘s pavement or
gravel);
the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in
spurts -- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out rnucit faster
if you
do a lot of heavy braking.
If you keep pace with the
traffic and allow realistic following distances, you
will
eliminate a lot of unnecessary braking. Th, ti t means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder
to push down. If your engine
stops,
you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used
up, it may take longer to stop and the brake pedal
will be harder
to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent
;1 braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system
will check itself. You may
hear
a momentary motor or clicking noise while this test
is going on. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light
will stay on.

Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back into
the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway
is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds.
A miscalculation, an error in
judgment, or a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road, to the sides and
to crossroads for situations that might affect your
passing patterns.
If you have any doubt whatsoever
about making a successful pass, wait for
a
better time.
0 Watch for traffic signs, pavement markings and lines.
If you can see
a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center
line usually indicates it‘s all right to pass
(providing the road ahead is clear). Never cross a solid
line on your side
of the lane or a double solid line,
even
if the road seems empty of approaching traffic.
Do not get too close to the vehicle you want to pass
while you‘re awaiting an opportunity. For one thing,
following too closely reduces
your area of vision,
especially
if you’re following a larger vehicle. Also,
you won’t have adequate space if the vehicle ahead
suddenly slows or stops. Keep back
a
reasonable distance.
When it looks like a chance to pass is coming up,
start to accelerate but stay
in the right lane and don’t
increasing speed as the time comes to move into the
other lane.
If the way is clear to pass, you will have a
“running start” that more than makes up for the
distance you would lose by dropping back. And
if
something happens to cause you to cancel your pass,
you need only slow down and drop back again
and
wait for another opportunity.
b cret too close. Time your move so you will be
If other cars are lined up to pass a slow vehicle, wait
your turn.
But take care that someone isn’t trying to
pass you
as you pull out to pass the slow vehicle.
Remember
to glance over your shoulder and check
the blind spot.

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
surfxes because stopping distance will be longer and
vehicle control more limited.
While driving on a surfxe
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 surfdce 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 Gu idelines
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 two-wheel-drive vehicles any more than
low-slung sports cars are designed to perform
satisfxtorily 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.

Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain.
You need to be familiar with the telrain and its
many different features. Here are some things to consider.
S~lr$uce Conditions. Off-roading can take you over
hard-packed dirt, gravel, rocks, grass, sand, mud, snow
or ice. Each of these surfaces affects the steering,
acceleration and braking of your vehicle
in different
ways. Depending upon the kind of surface
you are on,
you may experience slipping, sliding, wheel spinning,
delayed acceleration, poor traction and longer
braking distances.
Su$ace Obstucles . 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:
0 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.)
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
surhce 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.
