Driving and Operating 9-3
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.
Control of a Vehicle
The following three systems
help to control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of the
vehicle. See Traction Control
System (TCS) on page 9‑29.
Adding non‐dealer accessories
can affect vehicle performance.
See Accessories and Modifications
on page 10‑3.
Braking
See Brake System Warning Light on
page 5‑19.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average reaction time is about
three‐fourths of a second. But that
is 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 three‐fourths of a
second, a vehicle moving at
100 km/h (60 mph) travels
20 m (66 ft). That could be a lot of
distance in an emergency, so
keeping enough space between
the vehicle and others is important. And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
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. The brakes might not
have time to cool between hard
stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.

9-4 Driving and Operating
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is
applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
Adding non‐dealer accessories can
affect vehicle performance. See
Accessories and Modifications on
page 10‑3.Steering
Power Steering
If power steering assist is lost
because the engine stops or the
system is not functioning, the
vehicle can be steered but it will
take more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the road
surface, the angle at which the
curve is banked, and vehicle speed.
While in a curve, speed is the one
factor that can be controlled.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until 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. These problems can
be avoided by braking—if you can
stop in time. But sometimes you
cannot stop in time because there is
no room. That is the time for
evasive action —steering around
the problem.
The vehicle can perform very well in
emergencies like these. First apply
the brakes —but, unless the vehicle
has antilock brakes, not enough to
lock the wheels. See Braking on
page 9‑3. It is better to remove as
much speed as possible from a

Black plate (6,1)Chevrolet Impala Owner Manual - 2011
9-6 Driving and Operating
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 the vehicle's three control
systems. In the braking skid, the
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.
If the 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, the 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,
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.
While driving on a surface with
reduced traction, try 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
the 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 the vehicle has the Antilock Brake
System (ABS), remember: It helps
avoid only the braking skid. If the
vehicle does 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 and Operating 9-7
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.(Continued)
WARNING (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When your vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑38.
.Turn off cruise control.

Driving and Operating 9-9
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in
your own lane.
.Top of hills: Be
alert—something could
be in your lane (stalled car,
accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or
grip. Wet ice can occur at about
0°C (32°F) when freezing rain
begins to fall, resulting in even less
traction. Avoid driving on wet ice or
in freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction. Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑27 improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on
slippery surfaces.

Parking Brake
The parking brake is located to the
left of the brake pedal, near the
driver door.
To set the parking brake, hold the
brake pedal down, then push down
the parking brake pedal.
To release the parking brake, hold
the brake pedal down and push the
parking brake pedal. When you lift
your foot off the parking brake
pedal, the pedal will follow it to the
released position.A warning chime will sound and a
brake warning light located on the
instrument panel cluster will come
on, if the parking brake is set, the
ignition is on, and the vehicle speed
is greater than 8 km/h (5 mph).
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑41.
Ride Control Systems
Traction Control
System (TCS)
The vehicle may have a Traction
Control System (TCS) 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 transmission
and apply the front brakes to limit
wheel spin.
This light will flash when the TCS is
limiting wheel spin.
