GMC SAVANA 1996 Owners Manual

It’s the amount of alcohol that counts. For example, if
the same per3on drank
three double martinis (3 ounces
or 90 ml of liquor each) within an hour, the person’s
BAC would be close to 0.12 percent. A person who
consumes food just before or during drinking will have
a somewhat lower
BAC level.
There is
a gender difference, too. Women generally have
a lower relative percentage
of body water than men. Since alcohol is carried
in body water, this means that a
woman generally will reach a higher BAC level than
a
man of her same body weight when each has the same
number
of drinks.
The law in many
U.S. states sets the legal limit at a BAC
of
0. IO percent. In a growing number of U.S. states, and
throughout Canada, the limit is
0.08 percent. In some
other countries, it’s even lower. The BAC limit for all
commercial drivers in the United States is
0.04 percent.
The BAC will be over
0.10 percent after three to six
drinks (in one hour). Of course, as we’ve seen, it
depends on how much alcohol
is in the drinks, and how .
quickly the person drinks them.
But the ability
to drive is affected well below a BAC
of
0.10 percent. Research shows that the driving
skills of many people
are impaired at a BAC
approaching
0.05 percent, and that the effects are worse
at night. All drivers are impaired at BAC levels above
0.05 percent. Statistics show that the chance of being
in a collision increases sharply for drivers who have a
BAC
of 0.05 percent or above. A driver with a BAC level
of
0.06 percent has doubled his or her chance of having a
collision. At a BAC level
of 0.10 percent, the chance of
this driver having a collision
is 12 times greater; at a level
of 0.15 percent, the chance is 25 times greater!

The body takes about an hour to rid itself of the alcohol
in one drink. No amount of coffee or number of cold
showers will speed that up.
“I’ll be careful” isn’t the
right answer. What
if t.here’s an emergency, a need to
take sudden action,
as when a child darts into the street?
A person with even a moderate BAC might not be able
to react quickly enough to avoid the collision.
There’s something else about drinking and driving that
many people don’t know. Medical research shows that
alcohol
in a person‘s system can make crash injuries
worse, especially injuries to the brain, spinal cord or
heart. This means that when anyone
who has been
drinking
-- driver or passenger -- is in a crash, that
person’s chance
of being killed or permanently disabled
is higher than if the person had not been drinking.
I A CAUTION:
I
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness and
judgment can be affected by even a small amount
of alcohol. You can have a serious -- or even
fatal
-- collision if you drive after drinking.
Please don’t drink and drive or ride with
a driver
who has been drinking. Ride home in a cab; or if
you’re with
a group, designate a driver who will
not drink.

Control of a Vehicle
You have three systems that make your vehicle go where
you want
it to go. They are the brakes, the steering and
the accelerator. All three systems have
to do their work
at the places where the tires meet the road.
Sometimes,
as when you're driving on snow or ice, it's
easy to
ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's
perception time. Then you have to bring up
your foot and do it. That's reuction tirne.
Average wcrc'tion time is about 3/4 of a second. But
that's only an average. It might be less with one
driver and as long as two or three seconds or more
with another. Age, physical condition, alertness,
coordination and eyesight all play a part.
So do alcohol,
drugs and frustration.
But even in 3/4 of a second, a
vehicle moving at
60 mph (100 km/h) travels 66 feet
(20 m). That could be a lot of distance in an emergency,
so keeping enough space between your vehicle and
others
is important.
And,
of course, actual stopping distances vary greatly
with the surface of the road (whether it's pavement or
gravel); the condition
of the road (wet, dry, icy); tire
tread; and the condition
of your brakes.

Avoid needless heavy braking. Some people drive in
spurts -- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This
is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes
will wear out much
faster if you
do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you
will eliminate a lot of unnecessary braking. That
means better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder
to push down. If your engine
stops, you
will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that
will help
prevent
a braking skid.
When you start
your engine and begin to drive away,
your anti-lock brake system
will check itself. You may
hear
a momentary motor or clicking noise while this test
is going on. This is normal.
ANTI -
LOCK
If there’s a problem with
the anti-lock brake system,
this warning light will stay
on. See ”Anti-Lock Brake
System Warning Light’’
in
the Index.

Remember: Anti-lock doesn‘t change the time you need
to get your foot
up to the brake pedal or always decrease
stopping distance.
If you get too close to the vehicle in
front of you, you won‘t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead
to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal
down and let anti-lock work for you. You may feel the
brakes vibrate,
or you may notice some noise. but this
is normal.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock,
you can steer and brake at the same
time.
In many emergencies, steering can help you more
than even the very best braking.

Power Steering
If you lose power steering assist because the engine
stops
or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen
on curves. Here’s why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes
it
possible for the vehicle to change its path when you turn
the front wheels. If there‘s no traction, inertia will keep
the vehicle going
in the same direction. If you‘ve ever
tried to steer a vehicle on wet ice, you’ll understand this.
4-8
ProCarManuals.com

The traction you can get in a curve depends on the
condition
of your tires and the road surface, the angle
at which
the curve is banked, and your speed.
While you’re
in a curve, speed is the one factor you
can control.
Suppose you’re steering through a sharp curve. Then you
suddenly accelerate. Both control systems
-- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too
much
of those places. You can lose control.
What should you do
if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want
it
to go, and slow down.
Speed limit signs near curves warn that
you should
adjust your speed. Of course,
the posted speeds are
based
on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed as you approach a
curve, do
it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed
so you can “drive” through the
curve. Maintain
a reasonable, steady speed, Wait to
accelerate
until you are out of the curve, and then
accelerate gently into
the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking.
For example, you come over a hill and
find
a truck stopped in your lane, or a car suddenly
pulls out from nowhere, or a child darts out from
between parked cars and stops right
in front of you.
You can avoid these problems by braking -- if you
can stop
in time. But sometimes you can’t; there isn’t
room. That’s the time for evasive action
-- steering
around the problem.
Your vehicle can perform very
well in emergencies like
these. First apply your brakes. (See “Braking
in
Emergencies” earlier in this section.) It is better to
remove as much speed
as you can from a possible
collision. Then steer around the problem, to
the left or
right depending on the space available.
4-9
ProCarManuals.com

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 vesy quickly without re~noving
either- hand.
But you have to act fast, steer quickly, and
just as quickly straighten the wheel once
YOLI have
avoided the object.
The fact that such emergency situations are ~dways
possible
is a good reason to practice defensive driving at
all times and wear safety belts properly.
Off-Road R covery
You may find sometime that your right wheels have
dropped
off the edge of a road onto the shoulder while
you're driving.
OFF-ROAD
QUARTER TURN LEFT APPROX.
SLOW DOWN
edge of paved surface
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.

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 an, crer can
suddenly put
the passing driver fzce 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.
Wdtch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it's all right
to pass
(providing the road ahead is cleat-). 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
increasing speed as the time colnes to move into the
other lane.
If the way is clear to pass, you will have
a "running start" that more than makes LIP for the
distance you would lose by dropping back. And if
something happens to cause ~OLI to cancel your pass,
you need only slow clown and drop back again and
wait for another opportunity.
L' (ret too close. Time your move so you will be
Ii'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.
Re~ne~nber to glance over your shoulder and check
the blind
spot.

0 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.)
0 Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
0 Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are
not flashing, it
may be slowing down or starting to turn.
0 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.
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road
to do what the driver has asked.
In any emergency, don’t give up. Keep trying to
steer and constantly seek an escape route or area
of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions, and
by not ”overdriving” those conditions.
But skids are
always possible.
The three types
of skids correspond to your vehicle’s
three control systems.
In the braking skid, your wheels
aren’t rolling.
In the steering or cornering skid, too
much speed or steering
in a curve causes tires to slip and
lose cornering force. And
in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled
by easing your foot oft’ the accelerator pedal.
