Braking
SeeBrake System Warning Light on page 3-36.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That 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 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 is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your 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. 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 are driving, brake
normally but do not 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.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.

Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will come
on brie y when you
start your vehicle.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You
slam on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
4-7

If your vehicle is in cruise control when the traction
control 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 3-11.
The Traction Control System operates in all transaxle
shift lever positions except park or neutral. But the
system can upshift the transaxle only as high as the
shift lever position you’ve chosen, so you should use
the lower gears only when necessary. SeeAutomatic
Transaxle Operation (Base Models) on page 2-27
orAutomatic Transaxle Operation (SS Models)
on page 2-30.
When the system is off,
this warning light, located
on the instrument panel
cluster, will come on to
let you know if there’s
a problem, or if the system
has been turned off.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction Control
System on. But you can turn the system off if you prefer.
To turn the system on or off, press the TC button
located under the climate controls. In order to effectively
“rock” the vehicle, you will need to turn off TCS.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. Press the TC button again
to turn the system back on. The traction control system
warning light will go off.
When you turn the system off, the Traction Control
System warning light will come on and stay on. If the
Traction Control System is limiting wheel spin when you
press the button to turn the system off, the warning
light will come on — but the system won’t turn off right
away. It will wait until there’s no longer a current
need to limit wheel spin.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3for more information.

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.
This light will come on
when your Enhanced
Traction System is
engaged and limiting
wheel spin.
You may feel or hear the system working, but this is
normal.
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 3-11.The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you’ve
chosen, so you should use the lower gears only
when necessary.
When the system is on,
this warning light will
come on to let you know
there’s a problem.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
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.
4-11

To turn the system on
or off, press the traction
control button located
on the center console
under the climate
control system.
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on.
If the Enhanced Traction System is limiting wheel spin
when you press the button to turn the system off,
the warning light will come on — 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
pressing the button again. The traction control system
warning light should go off.Steering
Electric Power Steering
If your vehicle has the electric power steering system
and the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power steering
assist because the electric power steering system is not
functioning, you can steer, but it will take more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering assist.
The normal amount of power steering assist should return
shortly after a few normal steering movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems, contact your dealer for service repairs.
SeeDIC Warnings and Messages on page 3-50.
Hydraulic Power Steering
If your vehicle has the hydraulic power steering system
and you lose power steering assist because the engine
stops or the power steering system is not functioning, you
can steer, but it will take much more effort.
4-12

Hydroplaning
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 are going fast enough. When your vehicle
is hydroplaning, it has little or no contact with the road.
Hydroplaning does not 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 re ections 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 is not 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 cannot avoid deep puddles or standing water,
drive through them very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing water,
as you might at a low water crossing, your
vehicle can be carried away. As little as
six inches of owing water can carry away a
smaller vehicle. If this happens, you and other
vehicle occupants could drown. Do not ignore
police warning signs, and otherwise be very
cautious about trying to drive through
owing 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.
SeeTires on page 5-54.
