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 will be careful” is not the right answer. What if
there is 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 is something else about drinking and driving
that many people do not 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.
{CAUTION:
Drinking and then driving is very
dangerous. Your re exes, 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 do not drink and drive
or ride with a driver who has been
drinking. Ride home in a cab; or if you
are with a group, designate a driver
who will not drink.

Remember: ABS does not 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 will not 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 ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may
feel a slight brake pedal pulsation or notice some
noise, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a
situation that requires hard braking.
If you have ABS, you can steer and brake at the
same time. However, if you do not have ABS, your
rst reaction — to hit the brake pedal hard and
hold it down — may be the wrong thing to do.
Your wheels can stop rolling. Once they do, the
vehicle cannot respond to your steering.Momentum will carry it in whatever direction it was
headed when the wheels stopped rolling. That
could be off the road, into the very thing you were
trying to avoid, or into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can do this
by pushing on the brake pedal with steadily
increasing pressure.
In an emergency, you will probably want to
squeeze the brakes hard without locking the
wheels. If you hear or feel the wheels sliding, ease
off the brake pedal. This will help you retain
steering control. If you do have ABS, it is different.
SeeAnti-Lock Brake System (ABS) on page 243.
In many emergencies, steering can help you
more than even the very best braking.
245

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The
system operates only if it senses that one or
both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift
the transaxle to limit wheel spin. You may feel or
hear the system working, but this is normal.
A LOW TRACTION message will appear on the
Driver Information Center (DIC) when the traction
control system is actively limiting wheel spin.
Slippery road conditions may exist if this message
is displayed, so adjust your driving accordingly.
If your vehicle is in cruise control when the
Enhanced Traction System begins to limit wheel
spin, the cruise control will automatically
disengage. When road conditions allow you to
safely use it again, you may re-engage the cruise
control. SeeCruise Control on page 160.When the system is on,
this warning light will
come on to let you know
there’s a problem.
The Enhanced Traction System warning light may
come on for the following reasons:
If you turn the system off by moving the shift
lever to LOW (L), the warning light will come on
and stay on. To turn the system back on, move
the shift lever back to a position other than
LOW (L). The warning light should go off.
The warning light will come on when you set
your parking brake with the engine running, and
it will stay on if your parking brake does not
release fully. If the transaxle shift lever is in any
position other than LOW (L)and the warning
light stays on after your parking brake is fully
released, it means there is a problem with the
system.
If the traction control system is affected by an
engine related problem, the system will turn off
and the warning light will come on.
246

If the warning light stays on, or comes on when
you’re driving, there may be a problem with
your Enhanced Traction System and your vehicle
may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the transaxle shift lever is in any
position other than LOW (L), your vehicle needs
service.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system
off if you prefer.
To turn the system off, shift to LOW (L) or
REVERSE (R).When you turn the system off, the Enhanced
Traction System warning light will come on and stay
on when the gear shift is in LOW (L). The warning
light will not come on when the gear shift is in
REVERSE (R). If the Enhanced Traction System is
limiting wheel spin when you shift to LOW (L) or
REVERSE (R) to turn the system off, the warning
light will come on in LOW (L). But the system won’t
turn off right away. It will wait until there’s no longer
a current need to limit wheel spin.
You can turn the system back on at any time by
shifting to AUTOMATIC OVERDRIVE (D) or
INTERMEDIATE (I). The Enhanced Traction
System warning light should go off.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modifications on page 289for more information.

Watch 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 is
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 are awaiting an opportunity. For
one thing, following too closely reduces your
area of vision, especially if you are following a
larger vehicle. Also, you will not 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 do not 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 vehicles are lined up to pass a slow
vehicle, wait your turn. But take care that
someone is not 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 vehicle’s 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 vehicle’s inside
mirror, activate the right lane change signal and
move back into the right lane. Remember that
your vehicle’s passenger side 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.
Do not overtake a slowly moving vehicle too
rapidly. Even though the brake lamps are not
ashing, it may be slowing down or starting
to turn.
If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little to the right.
252

Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough
friction where the tires meet the road to do what the
driver has asked.
In any emergency, do not 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 are not 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 is best handled by easing your
foot off the accelerator pedal.
If you have the Enhanced Traction System (ETS),
remember: It helps to avoid only the acceleration
skid. SeeEnhanced Traction System (ETS)
on page 246. If you do not have the Enhanced
Traction System, or if the system is off, then
an acceleration skid is also best handled by easing
your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off
the accelerator pedal and quickly steer the
way you want the vehicle to go. If you start
steering quickly enough, your vehicle may
straighten out. Always be ready for a second skid
if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
253

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
If you have the Anti-Lock Brake System (ABS),
remember: It helps avoid only the braking skid. If
you do not have ABS, then in a braking skid,
where the wheels are no longer rolling, release
enough pressure on the brakes to get the wheels
rolling again. This restores steering control.
Push the brake pedal down steadily when you
have to stop suddenly. As long as the wheels are
rolling, you will have steering control.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.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot 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 vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.
254

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.
SeeTires on page 336.
City Driving
One of the biggest problems with city streets is
the amount of traffic on them. You will want
to watch out for what the other drivers are doing
and pay attention to traffic signals.
