length CHEVROLET SUBURBAN 1997 Owners Manual

Police records show that almost half of all motor
vehicle-related deaths involve alcohol.
In most cases,
these deaths are the result
of someone who was drinking
and driving. In recent years, some 17,000 annual motor
vehicle-related deaths have been associated with the use
of alcohol, with more than
300,000 people injured.
Many adults
-- by some estimates, nearly half the adult
population
-- choose never to drink alcohol, so they
never drive after drinking. For persons under 2
1, it’s
against the law in every
U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws.
The obvious way to solve this highway safety problem
is for people never to drink alcohol and then drive. But
what if people do?
How much is “too much” if the
driver plans to drive? It’s a lot less than many might
think. Although it depends on each person and situation,
here is some general information on the problem. The
Blood Alcohol Concentration (BAC)
of someone
who is drinking depends upon four things:
0 The amount of alcohol consumed
0 The drinker’s body weight
0 The amount of food that is consumed before and
during drinking
0 The length of time it has taken the drinker to
According to the American Medical Association, a
180-lb. (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about
0.06 percent. The person would reach the
same BAC by drinking three 4-ounce (120 ml) glasses
of wine or three mixed drinks
if each had 1 - 1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.

Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline of a hill. If this happens,
you have to decide
whether to try to drive across the incline. Here are some
things to consider:
0
0
0
A hill that can be driven straight up or down may be
too steep to drive across. When you go straight up or
down a hill, the length
of the wheel base (the
distance from the front wheels to the rear wheels)
reduces the likelihood the vehicle will tumble end
over end.
But when you drive across an incline, the
much more narrow track width (the distance between
the left and right wheels) may not prevent the vehicle
from tilting and rolling over. Also, driving across an
incline puts more weight on the downhill wheels.
This could cause a downhill slide or a rollover.
Surface conditions can be a problem when you drive
across a hill. Loose gravel, muddy spots, or even wet
grass can cause your tires
to slip sideways, downhill.
If the vehicle slips sideways, it can hit something
that will trip it (a rock, a rut, etc.) and roll over.
Hidden obstacles can make the steepness
of the
incline even worse. If you drive across a rock with
the uphill wheels, or if the downhill wheels drop into
a rut or depression, your vehicle can tilt even more. For reasons
like these, you need to decide carefully
whether to try to drive across an incline. Just because
the trail goes across the incline doesn’t mean you have
to drive it. The last vehicle to try it might have
rolled over.
--
Driving across an incline that’s too steep will
make your vehicle roll over.
You could be
seriously injured or killed. If you have any doubt
about the steepness of the incline, don’t drive
across it. Find another route instead.
Q: What if I’m driving across an incline that’s not
too steep, but I hit some loose gravel and start to
slide downhill. What should I do?
A: If you feel your vehicle starting to slide sideways,
turn downhill. This should help straighten out the
vehicle and prevent the side slipping. However,
a
much better way to prevent this is to get out and
“walk the course”
so you know what the surface is
like before you drive it.
