Once you decide you can safely drive
up the hill, you need to take some
special steps.
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.
Ease up on your speed as you
approach the top of the.hill..
Attach a flag to the vehicle to make
you more visible to approaching
traffic on trails or hills.
Sound the horn as you approach the
top of the hill to let opposing traffic
know you’re there.
Use your headlights even during the
day. They make you more visible to
oncoming traffic.
Q: What should I do if my vehicle
stalls,
or is about 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.
the transmission into reverse,
release the parking brake, and
slowly back down the hill in reverse.
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
P (Park) and
restart the engine. Then, shift to
reverse, release the parking brake,
and slowly back down the hill as
straight as possible in reverse.
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.
If your engine is still running, shift

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
N (Neutral) 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 into
reverse, 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.
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 P (Park), and turn off
the engine. Leave the vehicle and go get some nelp. 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:
How steep is the downhill? Will I be
able
to maintain vehicle control?
What’s the surface like? Smooth?
Rough? Slippery? Hard-packed 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?
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.
Q: Are there some things I should not
do when driving down a hill?
A: Yes! These are important because if
you ignore them you could lose
control and have a serious accident.
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 be too steep to
drive across. You could roll over
if
you don’t drive straight down.
transmission in
N (Neutral). This
is called “free-wheeling.” Your
brakes will have to do all the work
and could overheat and fade.
Never go downhill with the
ProCarManuals.com

Q: Am I likely to stall when going
downhill?
A It’s much more likely to happen
going uphill. But if it happens going
downhill, here’s what to do.
Stop your vehicle by applying the
regular brakes. Apply the parking
brake.
Shift to P (Park) and, while still
braking, restart the engine.
Shift back to a low gear, release the
parking brake, and drive straight
down.
If the engine won’t start, get out
and get help.
Driving Across an Incline
Sooner or later, an off-road trail will
probably go across the incline of a
hill. If
this happens, you have to decide
whether to
try to drive across the incline.
Here are some things to consider:
A hill that can be driven straight up or
down may be too steep to drive
across. When you go straight up or
down
a hill, the length of the wheel
base (the distance from the front wheels
to the rear wheels) reduces the
likelihood the vehicle will tumble end
over end. But when you drive across
an incline, the much more narrow
track width (the distance between the
left and right wheels) may not prevent
the vehicle from tilting and rolling
over. Also, driving across an incline
puts more weight
on the downhill
wheels. This could cause
a downhill
slide or a rollover.
Surface conditions can be a problem
when you drive across a hill. Loose
gravel, muddy spots, or even wet grass
can cause your tires to slip sideways,
downhill. If the vehicle slips sideways,
it can hit something that will trip it (a
rock, a rut, etc.) and roll over.
Hidden obstacles can make the
steepness of the incline even worse. If
you drive across a rock with the uphill
wheels, or if the downhill wheels drop
into a rut or depression, your vehicle
can tilt even more.
For reasons like these, you need to
decide carefully whether to
try to drive across
an incline. Just because the trail
goes across the incline doesn’t mean
you have to drive it. The last vehicle to
try it might have rolled over.
Q: What if I’m driving across an
incline that’s not too steep, but
I
hit some loose gravel and start to
slide downhill. What should I do?
A: If you feel your vehicle starting to
slide sideways, turn downhill. This
should help straighten out the
vehicle and prevent the side slipping.
However, a much better way to
prevent this is
to get out and “walk
the course”
so you know what the
surface is like before you drive it.

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.

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 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.
After OtY-Road Driving
Remove any brush or debris that has
collected on the underbody, chassis or
under the hood. These accumulations
can be a fire hazard.
After operation
in mud or sand, have
the brake linings cleaned and checked.
These substances can cause glazing and
uneven braking. Check the body
structure, steering, suspension, wheels,
tires, and exhaust system for damage.
Also, check the fuel lines and cooling
system for any leakage.
Your vehicle
will require more frequent
service due to off-road use. Refer to the
Maintenance Schedule for additional
information.

The exit ramp can be curved, sometimes
quite sharply.
The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of
motion. After driving for any distance at
higher speeds, you may tend to think you
are going slower than you actually are.
I Before Leaving on a Long
Tip
Make sure you’re ready. Try to be well
rested. If
you must start when you’re
not fresh
- such as after a day’s work
- don’t plan to make too many miles
that first part of the journey. Wear
comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready to go.
If it needs service, have it
done before starting out.
Of course,
you’ll find experienced and able service
experts in Oldsmobile dealerships all
across North America. They’ll be ready
and willing to help if you need it.
Here are some things you can check
before a trip:
Windshield Washer Fluid Is the
reservoir full? Are all windows clean
inside and outside?
shape?
you checked all levels?
Wiper Blades: Are they in good
Fuel, Engine Oil, Other Fluids: Have
Lights: Are they all working? Are the
lenses clean?
Tires: They are vitally important to a
safe, trouble-free trip. Is the tread
good enough for long-distance
driving? Are the tires all inflated to
the recommended pressure?
Weather Forecasts: What’s the
weather outlook along your route?
Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or
whatever.
There is something about an easy
stretch of road with the same scenery, along
with the hum of the tires on the
road, the drone of the engine, and the
rush of the wind against the vehicle that
can make you sleepy. Don’t let it
happen
to you! If it does, your vehicle
can leave the road in
less than a
second, and you could crash and be
injured.
What can you do about highway
hypnosis? First, be aware that it can
happen.
Then here are some tips:
Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road
ahead and to the sides. Check your
mirrors and your instruments
frequently.
If you get sleepy, pull off the road into
a rest, service, or parking area and
take a nap, get some exercise, or both.
For safety, treat drowsiness on the
highway as an emergency.

Winter Driving
Here are some tips for winter driving:
Have your Oldsmobile in good shape
for winter. Be sure your engine
coolant mix is correct.
You may want to put winter
emergency supplies in your vehicle.
Include an ice scraper,
a small brush or
broom,
a supply of windshield washer
fluid,
a rag, some winter outer clothing,
a small shovel, a flashlight, a red cloth,
and a couple of reflective warning
triangles. And, if you will be driving
under severe conditions, include a small
bag of sand, a piece of old carpet or a
couple
of burlap bags to help provide
traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where
your tires meet the road probably have
good traction.
However,
if there is snow or ice
between your tires and the road, you
can have a very slippery situation.
You’ll have a lot less traction or “grip”
and will need to be very careful.
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
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 ability to 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.

deal longer and not nearly so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, tires and mirror
adjustment.
If the trailer has electric
brakes, start your vehicle and trailer
moving and then apply the trailer brake
controller by hand to be sure the brakes
are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to
be sure that the load is secure, and that
the lights and any trailer brakes are still
working.
following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help
you avoid situations that
require heavy braking and sudden turns.
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer.
And, because you’re a good deal longer,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the
trailer to the left, just move that hand to
the left. To move the trailer to the right,
move your hand to the right. Always
back up slowly and, if possible, have
someone guide you.
Making Turns
When you’re turning with a trailer,
make wider turns than normal. Do this
so your trailer won’t strilte soft
shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.

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.
