light Oldsmobile Bravada 2003 s Repair Manual

An emergency like this requires close attention and a
quick decision.
If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you
can turn it a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer
quickly, and just as quickly straighten the wheel once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving
at all times and wear safety belts properly.
Off-Road Recovery
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you’re driving.
If the level of the shoulder
is only slightly below the
pavement, recovery should be fairly easy. Ease
off the
accelerator and then,
if there is nothing in the way,
steer
so that your vehicle straddles the edge of
the pavement.
You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
the pavement edge. Then turn your steering wheel
to go
straight down the roadway.
4-1 2

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.
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 on page 4-2.
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 understanding of what your vehicle can and can’t
do. There are some hills that simply can’t be driven, no
matter how well bui he vehicle.
Man) ills are ~..-.ply .,o steep for any vehicle.
If you drive up them, you will stall. If you drive
down them, you can’t control your speed.
If you
drive across them, you
will roll over. You could
be seriously injured or killed. If you have any
doubt about the steepness, don’t drive the hill.
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.
4-1 9

Q: 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.
Driving Downhill
When off-roading takes you downhill, you’ll want to
consider a number of things:
How steep is the downhill? Will I be able to maintain
vehicle control?
What’s the surface like? Smooth? Rough? Slippery?
Are there hidden surface obstacles? Ruts? Logs?
Hard-packed dirt? Gravel?
Boulders?
What’s at the bottom of the hill? Is there a there a
hidden creek bank or even a river bottom with
large rocks?
If you decide you can go down a hill safely, then
try to
keep your vehicle headed straight down, and use a
low gear. This way, engine drag can help your brakes
and they won’t have
to do all the work. Descend slowly,
keeping your vehicle under control at all times.
4-22
Heavy braki.., when going down a hill can
cause your brakes to overheat and fade. This
could cause
loss of control and a serious
accident. Apply the brakes lightly when
descending a hill and use a low gear to keep
vehicle speed under control.
Q: Are there some things I should not do when
driving down
a hill?
A: Yes! These are important because if you ignore
them you could
lose control and have a serious
accident.
When driving downhill, avoid turns that take you
across the incline
of the hill. A hill that’s not too
steep to drive down may be too steep to drive
across. You could roll over
if you don’t drive straight
down.
Never go downhill with the transmission in
NEUTRAL (N). This is called “free wheeling”. Your
brakes will have to do all the work and could
overheat and fade.

Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired
- by
alcohol or drugs, with night vision problems, or by fatigue. Here are
some tips on night driving.
Drive defensively.
Don’t drink and drive.
Since you can’t see as well, you may need to slow
down and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But
as we get older these differences increase.
A
50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your
night vision. For example,
if you spend the day in bright
sunshine you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to night. But
if
you’re driving, don’t wear sunglasses at night. They may
cut down on glare from headlamps, but they also make a lot of things invisible.

The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy
rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the road
and even people walking.
It’s wise to keep your wiping equipment
in good shape
and keep your windshield washer tank filled with
washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield, or when strips of rubber start
to
separate from the inserts. Driving too fast through large
water puddles or even
going through some car washes can cause problems,
too. The water may affect your brakes. Try to avoid
puddles. But
if you can’t, try to slow down before you
hi tem.

Wet brakes can cause accidents. They won’t
work as well in a quick stop and may cause
pulling to one side. You could lose control
of
the vehicle.
After driving through a large puddle
of water
or a car wash, apply your brake pedal lightly
until your brakes work normally.

Hydroplaning C ‘vir T’ lough --
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen
if the road is wet enough and
you’re going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can
if
your tires do not have much tread or if the pressure in
one or more is low.
It can happen if a lot of water is
standing on the road. If you can see reflections
from trees, telephone poles or other vehicles, and
raindrops “dimple” the water’s surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t
a hard and fast rule about hydroplaning.
The best advice
is to slow down when it is raining.
Driving Through Deep Standing Water
Notice: If you drive too quickly through deep
puddles or standing water, water can come
in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle.
If
you can’t avoid deep puddles or standing water,
drive through them very slowly.

Flowing or rushing water creates strong
forces.
If you try to drive through flowing
water, as you might
at a low water crossing,
your vehicle can be carried away.
As little as
six inches of flowing water can carry away
a
smaller vehicle. If this happens, you and other
vehicle occupants could drown. Don’t ignore police warning signs, and otherwise be very
cautious about trying to drive through flowing
water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared
to have your
view restricted by road spray.
Have good tires with proper tread depth. See Tires
on page 5-52.

City Driving One of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention
to traffic signals.
Here are ways to increase your safety
in city driving:
Know the best way to get to where you are
going. Get a city map and plan your trip into
an unknown part of the city just as you would for a
cross-country trip.
most large cities. You’ll save time and energy.
See
Freeway Driving on page 4-32.
Treat a green light as a warning signal. A traffic
light is there because the corner is busy enough
to need it. When a light turns green, and just before
you start to move, check both ways for vehicles
that have not cleared the intersection or may
be running the red light.
e Try to use the freeways that rim and crisscross
4-31

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to
move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance.
If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll be
ready and willing to help
if you need it.
Here are some things you can check before a trip:
e
0
e
Windshield Washer Fluid: Is the reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
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 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
very careful.
4-36

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
floor mats
- anything you can wrap around
yourself or tuck under your clothing to keep warm.
-.-
You can run the engine to keep warm, but be careful. Snow can trap ~,,raust
,,ses u..,er your
vehicle. This can cause deadly
CO (carbon
monoxide) gas to get inside.
CO could
overcome you and
kill you. You can’t see it or
smell
it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow
doesn’t collect there.
Open a window
just a little on the side of the
vehicle that’s away from the wind. This will
help keep
CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
