lock OLDSMOBILE BRAVADA 1997 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 sometime that your right wheels have
dropped off the edge of a road onto the shoulder while
you’re driving.
OFF- ROAD RECOVERY
/
7577 edge of paved surface
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
Oldsmobile’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 multiplrpose 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
LISLI~~~Y 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. Oldsmobile recognizes these concerns and
urges every off-roader to follow these basic rules for
protecting the environment:
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 from 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 OY oad 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.

Apm I ~ ~ ~ hing 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)?
0 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 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.
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.

0 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 mist 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.
0 Never attempt to turn around if you are about to stall
when going up
a hill. If the hili 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.
Q: 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.
Driving Downhill
When off-roading takes you downhill, you’ll want to
consider
a number of things:
0
0
0
0
How steep is the downhill? Will I be able to maintain
vehicle control?
What’s the surfice like? Smooth? Rough? Slippery?
Hard-pac ked dirt‘? Gravel?
Are there. hidden surface obstacles‘? Ruts?
Logs? Boulders?
What’s at the bottom
of the hill‘? Is there a hidden
creek bank
or even a river bottom with large rocks‘?

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; OOC) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever
the condition -- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Accelerate gently. Try not to break
the fragile traction. If
you accelerate too fast, the drive wheels will spin and
polish
the surface under the tires even more.
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.
Allow greater following distance on any
slippery road.
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.

Know 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 well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
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 uncomfortable
from the cold.
But 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 light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle,
on the driver’s side corner frame
crossmember. The heavy-duty trailer wiring has
a
30-amp feed wire with an inline fuse located by the
junction block. See “Fuses and Circuit Breakers”
in the
Index. Both harnesses have no connector and should be
wired by
ilt 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 (eight-wire harness only).
Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
White (Light Gage): 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.
