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.

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

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.

the side vents toward the side windows.
For increased air flow to the side vents,
close the center vents.

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.

To Add Coolant
If you need more coolant, add the proper
mix
at the coolant recovery tank.
Add coolant mix at the recovery tank,
but be careful not
to spill it.
I Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105 1tPa) pressure-type cap and
must be tightly installed
to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube
on the radiator
filler neck.
When you replace your radiator
pressure cap, an AC@ cap
is
recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow
of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
