Passing
The driver of a vehicle about to pass
another on a two-lane highway waits for
just the right moment, accelerates,
moves around the vehicle ahead, then
goes back into the right lane again.
A
simple maneuver?
Not necessarily! Passing another vehicle
on a two-lane highway is a potentially
dangerous move, since the passing
vehicle occupies the same lane as
oncoming traffic for several seconds.
A
miscalculation, an error in judgment, or
a brief surrender to frustration or anger
can suddenly put the passing driver face
to face with the worst of all traffic
accidents
- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road,
to the sides, and to crossroads for
situations that might affect your
passing patterns. If you have any
doubt whatsoever about making a
successful pass, wait for a better time.
markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
Watch for traffic signs, pavement pass.
A broken
center line usually
indicates it’s all right to pass
(providing the road ahead
is clear).
Never cross a solid line on your side
of the lane or a double solid line, even
if the road seems empty of
approaching traffic.
Do not get too close to the vehicle you
want to pass while you’re awaiting an
opportunity. For one thing, following
too closely reduces your area of vision,
especially
if you’re following a larger
vehicle.
Also, you won’t have
adequate space
if the vehicle ahead
suddenly slows or stops. Keep back a
reasonable distance.
When it looks like a chance to pass is
coming up, start to accelerate but stay
in the right lane and don’t get too close.
Time your move
so you will be
increasing speed as the time comes to
move into the other lane. If the way is
clear to pass, you
will have a “running
start” that more than makes up for the
distance you would lose by dropping
back. And
if something happens to
cause you to cancel your pass, you need
only slow down and drop back again
and wait for another opportunity.
If other cars are lined up to pass a
slow vehicle, wait your turn. But take
care that.someone isn’t trying to pass
you as you pull out to pass the slow
vehicle. Remember to glance over your
shoulder and check the blind spot.
Check your mirrors, glance over your
shoulder, and start your left lane
change signal before moving out of the
right lane to pass. When you are far
enough ahead of the passed vehicle to
see its front in your inside mirror,
activate your right lane change signal
and move back into the right lane.
(Remember that your right outside
mirror is convex. The vehicle you just
passed may seem to be farther away
from
you than it really is.)
Try not to pass more than one vehicle
at a time on two-lane roads. Reconsider
before passing the next vehicle.
Don’t overtake a slowly moving
vehicle
too rapidly. Even though the
brake lights are not flashing, it may be
slowing down or starting to turn.
If you’re being passed, make it easy
for the following driver to get ahead of
you. Perhaps you can ease a little to
the right.

Controlling your vehicle is the key to
successful off-road driving. One of the
best ways to control your vehicle is to
control your speed. Here are some
things to keep in mind. At higher
speeds:
you approach things faster and you
have less time to scan the terrain for
obstacles.
you have less time to react.
you have more vehicle bounce when
you drive over obstacles.
you’ll need more distance for braking,
especially since you’re on an unpaved
surface.
Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain.
You
need to be familiar with the terrain and
its many different features. Here are
some things to consider.
Surface Conditions
Off-roading can take you over hard-
packed
dirt, gravel, rocks, grass, sand,
mud, snow or ice. Each
of these surfaces
affects the steering, acceleration, and
braking of your vehicle in different ways.
Depending upon the kind of surface you
are on, you may experience slipping,
sliding, wheel spinning, delayed
acceleration, poor traction, and longer
braking distances.
Surface Obstacles
Unseen or hidden obstacles can be
hazardous. A rock, log, hole, rut, or
bump can startle you
if you’re not
prepared for them. Often these obstacles
are hidden by grass, bushes, snow or
even the rise and
fall of the terrain itself.
Here are some things to consider:
Is the path ahead clear?
Will the surface texture change
Does the travel take you uphill or
abruptly
up ahead?
downhill? (There’s more discussion of
these subjects later.)
change direction quickly?
Will you have to stop suddenly or
When you drive over obstacles or rough
terrain, keep a firm grip on the steering
wheel. Ruts, troughs, or other surface
features can jerk the wheel out of your
hands
if you’re not prepared.
When you drive over bumps, rocks, or
other obstacles, your wheels can leave
the ground. If this happens, even with
one or two wheels, you can’t control the
vehicle as well or at all.
Because you will be on an unpaved
surface, it’s especially important to
avoid sudden acceleration, sudden
turns, or sudden braking.
In a way, off-road driving requires a
different kind of alertness from driving
on paved roads and highways. There are
no road signs, posted speed limits or
signal lights.
You have to use your own
good judgment about what is safe and
what isn’t.

Your Driving and the Road

Drinking and driving can be very
dangerous on any road. And this is
certainly true for off-road driving. At the
very time you need special alertness and
driving skills, your reflexes, perceptions
and judgment can be affected by even a
small amount of alcohol.
You could
have a serious
- or even fatal -
accident if you drink and drive or ride
with a driver who has been drinking.
(See
Drunken Driving in the Index.)
Driving On Off-Road Hills
Off-road driving often takes you up,
down, or across a hill. Driving safely on
hills requires good judgment and an
understanding of what your vehicle can
and can’t do. There are some hills that
simply can’t be driven, no matter how
well built the vehicle.
Approaching a Hill
When you approach a hill, you need to
decide
if it’s one of those hills that’s just
too steep to climb, descend, or cross.
Steepness can be hard to judge. On a
very small hill, for example, there may
be a smooth, constant incline with only
a small change in elevation where you
can easily see all the way to the top. On
a large hill, the incline may get steeper
as you near the top, but you may not
see this because the crest of the hill is
hidden by bushes, grass, or shrubs.
Here are some other things to consider
as you approach a hill.
Is there a constant incline, or does the
hill get sharply steeper in places?
Is there good traction on the hillside,
or will the surface cause tire slipping?
Is there a straight path up or down
the hill
so you won’t have to make
turning maneuvers?
Are there obstructions on the hill that
can block your path (boulders, trees,
logs or ruts)?
What’s beyond the hill? Is there a cliff,
an embanlunent, a drop-off, a fence?
Get out and walk the hill
if you don’t
know. It’s the smart way to find out.
Is the hill simply too rough? Steep hills
often have ruts, gullies, troughs and
exposed rocks because they are more
susceptible to the effects of erosion.

Towinga Trailer
NOTICE:
Pulling a trailer improperly can
damage your vehicle and result in
costly repairs not covered by your
warranty. To pull a trailer correctly,
follow the advice in this section,
and see your Oldsmobile dealer for
important information about
towing a trailer with your vehicle. Every Bravada is ready for some trailer
towing. If it was built with trailering
options, as many are, it’s ready for
heavier trailers. But trailering is different
than just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful,
safe trailering takes correct equipment,
and it has to be used properly.
That’s thereason for this section. In it are
many time-tested, important trailering
tips and safety rules. Many
of these are
important for your safety and that of your
passengers.
So please read this section
carefully before you pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws having
to do with trailering. Make sure your
rig will be legal, not only where you
live but
also where you’ll be driving. A
good source for this information can
be state or provincial police.
Consider using a sway control if your
trailer will weigh
2,000 pounds (900
kg) or less. You should always use a
sway control if your trailer will weigh
more than
2,000 pounds (900 kg). You
can ask
a hitch dealer about sway
controls.
Don’t tow a trailer at all during the
first
500 miles (800 lun) your new
vehicle is driven. Your engine, axle or
other parts could be damaged.
Then, during the first 500 miles (800
km) that you tow a trailer, don’t drive
over
50 mph (80 km/h) and don’t
make starts at full throttle. This helps
your engine and other parts of your
vehicle wear in at the heavier loads.
Three important considerations have
to
do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
5,250
pounds (2 380 kg). But even that can be
too heavy.
It depends on how you plan to use your
rig. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a
trailer are all important. And, it can also
depend on any special equipment that
you have on your vehicle.

An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0°F (-18°C) or colder. If
your vehicle has this option, see Engine
Coolant Heater
in the Index.
What to Do with Used Oil
Did you laow that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer? Don’t let used oil stay on
your skin for very long. Clean your skin
and nails with soap and water, or a
good hand cleaner. Wash or properly
throw away clothing or rags containing
used engine oil. (See the manufacturer’s
warnings about the use and disposal of
oil products.)
Used oil can be a real threat to the
environment.
If you change your own
oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t
ever dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies
of
water. Instead, recycle it by taking it to a
place that collects used oil.
If you have a
problem properly disposing of your used
oil, ask your dealer, a service station or a
local recycling center for help.

Automatic Transmission Fluid
When to Check and Change
4 good time to check your automatic
transmission fluid level is when the
:ngine oil is changed. Refer to the
Maintenance Schedule to determine
when to change your fluid. See
Scheduled Maintenance Services in
the
Index.
How to Check
Because this operation can be a little
difficult, you may choose to have this
done at an Oldsmobile dealership
Service Department.
If you do it yourself, be sure to follow
all the instructions here, or you could
get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can
damage your transmission.
Too
much can mean that some of the
fluid could come out and fall on hot
engine parts or exhaust system,
starting a fire. Be sure to get an
accurate reading if you check your
transmission fluid.
Wait at least
30 minutes before
checking the transmission fluid level if
you have been driving:
When outside temperatures are abovc

90°F (32°C).
In
heavy traffic - especially in hot
weather.
While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is
180°F to 200°F
(82°C to 93°C).
To Check Transmission Fluid Hot:
Get the vehicle warmed up by driving
about
15 miles (24 km) when outside
temperatures are above
50°F (10°C). If
it's colder than
50°F ( 10°C), drive the
vehicle in
D (3rd Gear) until the engine
temperature gage moves and then
remains steady for ten minutes. Then
follow the hot check procedures.
To Check Transmission Fluid Cold:
A cold check is made after the vehicle
has been sitting for eight hours or more
with the engine off and is used only as a
reference. Let the engine run at idle for
five minutes if outside temperatures are
50°F (10°C) or more. If it's colder than
50°F (lO"C), you may have to idle the
engine longer. Should the fluid level be
low during a cold check, you
must
perform a hot check before adding fluid.
This will give you a more accurate
reading of the fluid level.

9. Air Cleaner Filter Replacement': -
Replace every 30,000 miles (50 000
km) or more often under dusty
conditions. Ask your dealer for the
proper replacement intervals for your
driving conditions.
10. Fuel Tank, Cap and Lines
Inspection*t
- Inspect fuel tank,
cap and lines (including fuel rails
and injection assembly) for damage
or leaks. Inspect fuel cap gasket for
an even filler neck imprint or any
damage. Replace parts as needed.
1 1. Positive Crankcase Ventilation
(PCV) System 1nspection':t

Inspect the system for proper
function. Replace any worn, plugged
or collapsed hoses and seals.
Replace valve only if necessary.
12. Fuel Filter Replacement'$t -
Replace the fuel filter every 30,000
miles (50 000 ltrn), or sooner if
clogged.
13. Engine Timing and Distributor Check':'t
- Adjust the timing to
the underhood label specifications.
Inspect the inside and outside of the
distributor cap and rotor for craclts, carbon tracking and corrosion.
Clean or replace
as needed.
14. Differential (Axle) Service-Check
rear/front differential fluid level and
add as needed. Check constant
velocity joints and axle seals for
leaking.
Locking Rear Differential -Drain
fluid at first engine oil change and
refill. Check fluid level and add as
needed at subsequent oil changes. In
dusty areas, or trailer towing
applications, drain fluid at every
15,000 miles (25 000 ltm) and refill.
More frequent lubrication may be
required during heavy-duty or off-
road use. A fluid loss in this system
may indicate
a problem. Have it
inspected and repaired at once.
15. Brake Systems Inspection-When
the engine oil is changed, inspect
the lines and hoses for proper
hookup, binding, leaks, craclts,
chafing, etc. Check the parking
brake adjustment and the fluid level
in the master cylinder. A low brake
fluid level can indicate worn disc
brake pads which may need to be
serviced.
A fluid loss in this system may indicate a problem. See
the
Index under Brake System Warning
Light. When the wheels are
removed for rotation, inspect disc
brake pads for wear and rotors for
surface condition. Also inspect
drum brake linings for wear and
craclts. Inspect other brake parts,
including drums, wheel cylinders,
calipers, parking brake, etc. at the
same time.
You may need to have your brakes
inspected more often
if your driving
habits or conditions result in
frequent braking.
16. Transfer Case Fluid Change -In
heavy or frequent trailer towing
applications, drain fluid and refill
every
30,000 miles (50 000 ltm).
