Notice:If you operate the convertible top switch
continuously while the ignition is in ACCESSORY,
the battery will drain and you might not be able
to start your vehicle. Do not use the convertible top
switch for extended periods of time when the
ignition is in ACCESSORY.

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 are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can
lose control of your vehicle.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.
Braking
SeeBrake System Warning Light on page 3-30.
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.
4-6
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 has anti-lock brakes. 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.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-31.
4-7
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly 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
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
(Automatic Transmission)
Your 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 rear wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also up-shift the transmission to limit wheel spin.
You may feel or hear the system working, but this
is normal.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 3-10.
The Traction Control System operates in all transmission
shift lever positions except for FIRST (1). This is
normal. The system is deactivated when the
transmission is shifted into FIRST (1). In this situation,
the traction control system warning light on the
instrument panel cluster will come on. This is normal.
The system can upshift the transmission only as high as
the shift lever position you’ve chosen, so you should
use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-19.
When the system is on,
this warning light will come
on to let you know if
there’s a problem.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
4-9
If the Traction Control System (TCS) is on and you drive
faster than 100 mph (161 km/h), the system will turn
off and the TC warning light will come on. The TCS will
turn back on and the TC warning light will go out
once the vehicle speed falls below 90 mph (145 km/h).
SeeTraction Control System (TCS) Warning Light
on page 3-32.
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
ever need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking Your
Vehicle to Get It Out on page 4-28andIf Your Vehicle
is Stuck in Sand, Mud, Ice or Snow on page 4-28
for more information.To turn the system on or
off, press the traction
control button located on
your center console
switchbank. SeeCenter
Console Switchbank on
page 3-19for more
information.
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 and the system will turn off right away.
You can turn the system back on at any time by
pressing the button again. The Traction Control System
warning light should go off.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3for more information.
4-10
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 reflections
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
•Turn on your low-beam headlamps — not just
your parking lamps — to help make you more
visible to others.
•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 5-51.
