Torque Lock
If you are parking on a hill and you
don’t shift your transmission into
P
(Park) properly, the weight of the
vehicle may put too much force on the
parking pawl in the transmission. You
may find it difficult
to pull the shift
lever out of
P (Park). This is called
“torque lock.”
To prevent torque lock,
set the parking brake and then shift into
P (Park) properly before you leave the
driver’s seat.
To find out how, see
Shifting Into P (Park) in the Index.
When you are ready to drive, move the
shift lever out of
P (Park) BEFORE you
release the parking brake.
If “torque lock” does occur, you may
need to have another vehicle push yours
a little uphill to take some
of the
pressure from the transmission,
so you
can pull the
shift lever out of P (Park).

Driving Uphi//
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.

Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving
in flat or rolling
terrain.
If you drive regularly in steep country,
or
if you’re planning to visit there, here
are some tips that can make your trips
safer and more enjoyable. (See
Off-
Road Driving in the Index for
information about driving off-road.)
Keep your vehicle in good shape.
Check
all fluid levels and also the
brakes, tires, cooling system and
transmission. These parts can work
hard on mountain roads.
how how to go down hills. The most
important thing to how is this: let
your engine do some
of the slowing down.
Shift to
a lower gear when you
go
down a steep or long hill.
Know how to go uphill. You may
want to shift
down to a lower gear.
The lower gears help cool your engine
and transmission, and you can climb
the hill better.
Stay in your own lane when driving on
two-lane roads in hills or mountains.
Don’t swing wide or cut across the
center of the road. Drive at speeds that
let you stay in your
own lane.
As you go over the top of a hill, be
alert. There could be something in
your lane, like a stalled car or an
accident.
You may see highway signs on
mountains that warn of special
problems. Examples are long grades,
passing or no-passing zones, a falling
rocks area, or winding roads. Be alert
to these and tale appropriate action.

Your Driving and the Road
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,

NOTICE:
~~
Ignoring these steps could result in
costly damage to your vehicle that
wouldn’t be covered by your
warranty. Trying to start your
Oldsmobile by pushing or pulling it
won’t work, and it could damage
your vehicle.
To Jump Start Your Oldsmobile:
1. Check the other vehicle. It must have
a 12-volt battery with a negative
ground system.
NOTICE:
If the other system isn’t a 12-volt
system with a negative ground,
both vehicles can be damaged.
2. Get the vehicles close enough so the
jumper cables can reach, but be sure
the vehicles aren’t touching each
other. If they are, it could cause a
ground connection you don’t want.
You wouldn’t be able to start your
Oldsmobile, and the bad grounding
could damage the electrical systems.
You could be injured if the vehicles roll.
Set the parking brake
firmly on each
vehicle. Put an automatic transmission
in P (Park) or a manual transmission in
N (Neutral).
3. Turn off the ignition on both
vehicles. Turn
off all lights that aren’t
needed, and radios. This will avoid
sparks and help save both batteries.
And it could save your radio!
NOTICE:
If you leave your radio on, it could
be badly damaged. The repairs
wouldn’t be covered by your
warranty.
4. Open the hoods and locate the
batteries. Find the positive
(+) and
negative
(-) terminals on each
battery.

When your vehicle is being towed, have
the ignition key off. The steering wheel
should be clamped in a straight-ahead
position, with a clamping device
designed for towing service.
Do not use
the vehicle’s steering column lock for
this. The transmission should be in
P (Park) and the parking brake
released.
Don’t have your Bravada towed with
the wheels in contact with the ground.
If your vehicle is being towed with
sling-type or wheel-lift equipment,
either the front or rear wheels must be
supported on a dolly.
If towing your Bravada with a car
carrier, block supports may be required
to prevent damage to the vehicle.

Engine Fan Noise
This vehicle has a clutched engine
cooling fan. When the clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most everyday
driving conditions the clutch is not
engaged. This improves fuel economy
and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or
high outside temperatures, the fan speed
increases when the clutch engages.
So
you may hear an increase in fan noise.
This is normal and should not be
mistaken as the transmission slipping or
making extra shifts. It is merely the
cooling system functioning properly.
The fan will slow down when additional
cooling is not required and the clutch
disengages. You may also hear this fan
noise when you start the engine. It will
go away
as the fan clutch disengages.
I Ifa Tire Goes Flat
It’s unusual for a tire to “blow out”
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire
will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the same correction you’d use in a skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes
flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.
I Changing a Flat Tire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn
on your hazard
warning flashers.
