Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (1 6 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other.
AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise
if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful
to your hearing. Take precautions by
adjusting
the volume control on your radio to a safe
sound level before your hearing adapts to it.

Operating Your Bravada Off Paved Roads
Many of the s’ame design features that help make
Bravada responsive on paved roads during poor weather conditions
-- features like the locking rear axle and
all-wheel drive
-.- help make it much better suited for.
off-road use than a conventional passenger car. Its
higher.ground clearance also helps Bravada step over
some off-road obstacles. But Bravada doesn’t have
features like special underbody shielding and a transfer
case low gear range, things that are usually thought
necessary for extended or severe off-road service. This
guide is for operating your Bravada off paved roads.
Also, see “Anti-Lock Brakes” in the Index.
Off-road driving can be great fun. But it does have
I r some definite hazards. The greatest of these is the
’ terrain itself.
t
“Off-roading” means you’ve left the great North
marked. Curves aren’t banked. There are no road signs.
Surfaces can be slippery, rough, uphill or downhill. In
Off-road driving involves some new skills. And that’s
why it’s very important that you read this guide. You’ll
find many driving tips and suggestions. These will help

hort, you’ve gone right back
to nature.
Before You Go Off-Roading
There are some things to do before ,you go out. For
example, be sure to have all necessary maintenance and
service work done. Check to make sure all underbody
shields (if
so equipped) are properly attached. Be sure
you read all the information about your
four-wheel-drive vehicle in this manual.
Is there enough
fuel? Is the spare tire fully inflated? Are the fluid levels
up where they should be? What are the local laws that
apply to off-roading where you’ll be driving?
If you
don’t
know, you should check with law enforcement
people in the area. Will you be on someone’s private
land? If
so, be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain doesn’t toss things around.

Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load floor can
be tossed about when driving over rough
terrain. You or your passengers can
be struck by flying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center
of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the roof.
Keep cargo in the cargo area as far forward
and low as possible.
You’ll find other important information in this manual.

in the Index.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However,
it also raises environmental
concerns. Oldsmobile recognizes these concerns
and
urges every off-roader to follow these basic rules for
protecting the environment:

Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving: obey
all posted regulations.
Avoid any driving practice that could damage the
environment
-- shrubs. flowers, trees, grasses -- or
disturb wildlife (this includes wheel-spinning.
breaking down trees
or unnecessary driving through
streams or over soft ground).
Always carry
a litter bag . . . make sure all refuse is
removed from any campsite before leaving.
Take extreme care
with open fires (where permitted),
camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch
fire from the
heat of the vehicle‘s exhaust system.

Winter Driving
Here are some tips for winter driving:
0 Have your Oldsmobile in good shape for winter.
0 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.

Driving with a Trailer
A CAUTION:
If you have a rear-most window open and you
pull
a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.)
To
maximize your safety when towing a trailer:
a
a
a
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through
a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
MAX A/C because.it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.)
L
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yaurself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle
you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
’
lamps, 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 ,lamps and any trailer brakes
are still working.

Trailer Wiring Harness
The light duty trailer wiring is a six-wire harness
assembly. The optional heavy duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, on the driver’s side corner frame
crossmember. The heavy duty trailer wiring
has a
30-amp feed wire with an inline fuse located by the
junction block. See “Fuses and Circuit Breakers”
in the
Index. Both harnesses have no 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.
0 DARK BLUE: Use for electric trailer brakes or
auxiliary wiring.
0 RED: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 LIGHT GREEN: Back-up lamps (eight-wire
harness only).
BROWN: Taillamps and parking lamps.
YELLOW: Left stoplamp and turn signal.
DARK GREEN: Right stoplamp and turn signal.
WHITE (Heavy Gage): Ground wire.
WHITE (Light Gage): 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.
