lock OLDSMOBILE BRAVADA 1998 Workshop Manual

An emergency like this requires close attention and a
quick decision. If you
are holding the steering wheel at ’
the recommended 9 and 3 o’clock positions, you can
turn it a full
180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly.
Off-Road Recovery
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you’re driving.
If the level
of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease
off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to one-quarter turn
until the right front tire contacts the pavement edge. Then turn your steering wheel to go straight down the roadway.

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.
111 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,
c gravel or other material is on the road. For safety, you'll
want to slow down
and ad-just 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 OF
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 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.
Operating Your Bravada
Off Paved Roads
Many of the same design features that help make
Bravada responsive
on paved roads during poor weather
conditions
-- features like the locking rear axle and
all-wheel drive
-- help make it much better suited for
off-road use than
a conventional passenger car. Its
higher ground clearance also helps Bravada step over
some off-road obstacles.
But Bravada doesn‘t have
features like special underbody shielding and a transfer
case low gear range, things that are usually thought
necessary for extended or severe off-road service. This
guide is for operating your Bravada off paved roads.
Also, see “Anti-Lock Brakes” in the Index.
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.

Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However,
it also raises environmental
concerns.
GM recognizes these concerns and urges
every off-roader to follow these basic rules for
protecting the environment:
0
0
0
0
0
Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage
the
environment -- shrubs, flowers, trees, grasses -- or
disturb wildlife (this includes wheel-spinning,
breaking down trees or unnecessary driving through
streams or
over soft ground).
Always carry a litter bag
. . . make sure all refuse is
removed
f~'om any campsite before leaving.
Take extreme care
with open fires (where permitted),
camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch fire from the
heat of the vehicle's exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to
a remote area. Know the terrain and plan your route.
You are much less likely to get bad surprises. Get
accurate maps of trails and terrain.
Try to learn of any
blocked or closed roads.
It's also
a good idea to travel with at least one other
vehicle.
If something happens to one of them, the other
can help quickly.
Getting Familiar with Off-Road Driving
It's a good idea to practice in an area that's safe and
close to home before you go into the wilderness.
Off-road driving does require some new and different
driving skills. Here's what we mean.
Tune your senses to different kinds
of signals. Your
eyes, for example, need to constantly sweep
the terrain
for unexpected obstacles. Your ears need to listen for
unusual tire or engine sounds. With
your arms, hands,
feet and body, you'll need to respond to vibrations and
vehicle bounce.

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.
Here are some other things to consider as you approach
a
hill.
0 Is there a constant incline, or does the hill get sharply
steeper
in places?
Is there good traction on the hillside, or will the
surface cause tire slipping?
0 Is there a straight path up or down the hill so you
won’t have to make turning maneuvers‘?
0 Are there obstructions on the hill that can block your
path (boulders, trees,
logs or ruts)?
What’s beyond the hill? Is there a cliff, an
embankment,
a drop-off, a fence? Get out and
walk the
hill if you don’t know. It’s the smart way
to find out.
Is the hill simply too rough‘? Steep hills often have
ruts, gullies, troughs and exposed rocks because they
are more susceptible to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.
0
0
0
Use a low gear and get a firm grip on the
steering wheel.
Get a smooth start
up the hill and try to maintain
your speed. Don’t use more power than you need,
because you don’t want your wheels to start spinning
or sliding.
Try to drive straight
up the hill if at all possible. If
the path twists and turns, you might want to find
another route.

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.
0 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.
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.
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.

What’s the worst time for this? “Wet ice.” Very cold
snow
or ice can be slick and hard to drive on. But wet
ice can be even more trouble because
it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32°F; 0°C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever

Your anti-lock brakes improve your vehicle’s stability
when
you make a hard stop on a slippery road. Even
though you have an anti-lock braking system, you‘ll
want to begin stopping sooner- than
you would on dry
pavement. See “Anti-Lock“
in the Index.
0 Allow greater following distance on any
slippery road.
0 Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear
in
shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface of a curve
or an overpass may
remain icy when the surrounding roads are clear.
If
you see a patch of ice ahead of you, brake before you
are
on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can't see it or smell it,
so you might not
know it is
in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open
a window just a little on the side of the
vehicle that's away from the wind. This
will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine. make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for
the heat that you get and it keeps the
battery charged. You will need
a we.11-charged battery to
restart the vehicle. and possibly
for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and
close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncornfortable
from the
cold. BLI~ do it as little as possible. Preserve the
fuel
as long as you can. To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Trailer Wiring Harness
The trailer wiring harness is an eight-wire harness
assembly. The harness
is stored under the vehicle, on the
driver's side corner frame crossmember. The harness has
a 30-amp feed wire
with an inline fuse located by the
junction block. See "Fuses and Circuit Breakers"
in the
Index. The harness does not have
a connector and
should be wired by
a qualified electrical technician. The
technician can use the following color code chart when
connecting
the wiring harness to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
Red: Use for battery charging; it connects to the
starter solenoid.
Light Green: Back-up lamps.
Brown: Tdillarnps and parking lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gauge): Ground wire.
White (Light Gauge): Auxiliary stoplamp.
Securely attach the harness to the trailer, then tape
or strap it to your vehicle's frame rail. Be sure you leave
it loose enough so the wiring doesn't bend or break, but
not
so loose that it drags on the ground. Store the
harness
in its original place. Wrap the harness together
and tie
it neatly so it won't be damaged.
