Tilt Steering Wheel
A tilt steering wheel allows you to
adjust the steering wheel before you
drive. You can also raise it to the
highest level to give your legs more
room when you exit and enter the
vehicle.
To tilt the wheel, hold the steering
wheel and pull the lever. Move the
steering wheel
to a comfortable level,
then release the lever to lock the wheel
in place.

Anti-Lock Brakes (ABS)
Your vehicle has an advanced electronic
braking system that can help you keep
it under control. When you start your
vehicle and begin to drive away, you
may hear a momentary motor or
clicking noise. This is the ABS system
testing itself. Here’s how anti-lock works.
Let’s say
the road is wet. You’re driving safely.
Suddenly an animal jumps out in front
You slam on the brakes. Here’s what
happens with
ABS.
A computer senses that the wheels are
slowing down. If one of the wheels is
about to stop rolling, the computer will
separately work the brakes at each front
wheel and at the rear wheels. The anti-
lock system can change the brake
pressure faster than any driver could.
The computer is programmed to make
the most of available tire and road
conditions. You can steer around the
obstacle while braking hard.
of
you.
As you brake, your computer keeps
receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn’t change
the time you need to get your foot up to
the brake pedal.
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.
To Use Four-wheel 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.

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.

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, you’ll 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.
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.
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. Unless you have traction control
and the system is on, 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.

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
quicldy 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 braking
system (ABS) helps avoid only the
braking skid.

Controlling your vehicle is the key to
successful off-road driving. One of the
best ways to control your vehicle is to
control your speed. Here are some
things to keep in mind. At higher
speeds:
you approach things faster and you
have less time to scan the terrain for
obstacles.
you have less time to react.
you have more vehicle bounce when
you drive over obstacles.
you’ll need more distance for braking,
especially since you’re on an unpaved
surface.
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.
Surface 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.
Surface 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?
Will the surface texture change
Does the travel take you uphill or
abruptly
up ahead?
downhill? (There’s more discussion of
these subjects later.)
change direction quickly?
Will you have to stop suddenly or
When you drive over obstacles or rough
terrain, keep a firm grip on the steering
wheel. Ruts, troughs, or other surface
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.

Stalling on an Mine
If your vehicle stalls when you’re
crossing an incline, be sure you (and
your passengers) get
out on the uphill
side, even if the door there is harder to
open. If you get out on the downhill
side and the vehicle starts to roll over,
you’ll be right in its path.
If you have to walk down the slope, stay
out of the path the vehicle will take if it
does roll over.
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, 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.

Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not, It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift
down, you
might have to use your brakes
so much
that they would get hot and no longer
work well. On
a long uphill grade, shift down and
reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If you are towing a trailer that weighs
more than
3,000 pounds (1 350 kg), it’s
best to drive in
D instead of Overdrive
(or, as you need to, a lower gear). This
will minimize heat build-up and extend
the life of your transmission.
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake and then
shift to
P (Park).
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on
a Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of
the chocks.
store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more
often when you’re pulling a trailer. See
the Maintenance Schedule for more on
this. Things that are especially
important in trailer operation are
automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt,
cooling system, and brake adjustment.
Each of these is covered in this manual,

Towing Your Bravada
Try to have a GM dealer or a
professional towing service tow your
vehicle. The usual towing equipment is:
(A) Sling-type tow truck
(B) Wheel-lift tow truck
(C) Car carrier
If your vehicle has been changed or
modified since it was factory-new by
adding aftermarket items like aero
skirting or special tires and wheels,
these instructions may not be correct.
Before you do anything, turn on the
hazard warning flashers.
NOTICE:
Dollies must be used on ground
wheels or vehicle damage will occur.
When you call, tell the towing service:
That your vehicle has all-wheel drive
and cannot be towed with any wheels
in contact with the ground. Your
vehicle requires dollies with sling-type
or wheel-lift equipment, or a car
carrier.
The make, model, and year of your
vehicle.
Whether you can still move the shift
lever.
If there was an accident, what was
damaged.
When the towing service arrives, let the
tow operator how that this manual
contains towing instructions. The
operator may want to see them.
