VOLTS
Voltmeter (STANDARD CLUSTER)
Your charging system gage will show
the rate of charge when the engine is
running. When the engine is not
running but the ignition is on (in the
Run position), the display measures thc
voltage output of your battery.
The reading will change as the rate
of
charge changes (with engine speed,
etc.), but readings between the warning
zones indicate the normal operating
range. Readings in either warning zone
indicate a possible problem with your
charging system. Have your Oldsmobilc
serviced immediately.

Brake System Warning Light
Your Oldsmobile’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 as you start
the vehicle. If it doesn’t come on then,
have it fixed
so it will be ready 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 Truck in the Index.)
The brake system warning light will also
come on when you set your parking
brake, and it 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.

ducts at your feet. At times this
temperature difference may be more
apparent than others.
VENT: The vent setting brings in
outside air through the instrument
panel outlets and at your front side
windows.
HTR The heater setting brings in most
heated air through the heater ducts, and
some through the defroster vents.
If you have the optional engine coolant
heater and use it during cold weather,
20°F (-8°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Coolant Heater.

windshield and side windows. Some
will also
go to the floor vents.
The air conditioner will also run in this
setting to remove moisture from the air
when the temperature is above
40°F
(4°C). Adjust the temperature control
as desired.

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,
ProCarManuals.com

Here you’ll find what to do about some
problems that can occur on the road

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.
