1998 OLDSMOBILE BRAVADA parking brake

Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on
if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it
means you have a brake problem.
Your vehicle‘s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can
still work and stop you. For good braking, though. you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on
BRAKE
-
briefly when you turn the
ignition key to
RUN. If it
doesn’t come on then,
have
it fixed so it will be
re.ady to warn you
if
there’s a problem.
If the light comes on while you are driving, pull off the
road and stop carefully.
You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have. the
vehicle towed for service. (See “Towing Your Vehicle“
in the Index.)
I CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
1 with the brake system warning light on can lead
~ to an accident. If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.

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 headlamps even during the day. They make
you more visible to oncoming traffic.
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:
0 Push the brake pedal to stop the vehicle and keep it
from rolling backwards.
Also, apply the parking brake.
0 If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill in
REVERSE (R).

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.

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 PARK (P) 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.
0 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.

When towing a trailer, the 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.
You should use THIRD
(3) when towing a trailer.
Operating your vehicle in THIRD
(3) when towing a
trailer will minimize heat buildup 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
PARK (P) yet. Then turn your wheels into the
curb
if facing downhill or into traffic if facing uphill.
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

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;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and 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, and‘the Index will help you
find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight

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.

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 vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly
on both vehicles involved in
the procedure. Put an automatic transmission vehicle
in
PARK (P) and a manual transmission vehicle in
NEUTRAL (N).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter, or accessory power outlets,
if you have this
option. Turn
off all lamps that aren’t needed as well
as radios. This will avoid sparks and help to save
both batteries. In addition,
it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn’t be covered by
your warranty.
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
