3-86

Braking
SeeBrake System Warning Light on page 3-62.
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 Modications
on page 5-3.
4-6

Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System (ABS), an
advanced electronic braking system that will help prevent
a braking skid.
When you start your engine and begin to drive away,
ABS will check itself. You may hear a momentary motor
or clicking noise while this test is going on, and you may
even notice that your brake pedal moves a little.
This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-63.
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 front wheel
and at both rear wheels.
4-7

Traction Control System (TCS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that the
front wheels are spinning too much or beginning to lose
traction. When this happens, the system works the front
brakes and reduces engine power (by closing the throttle
and managing engine spark) to limit wheel spin.
The traction control system and StabiliTrak
®warning
light will ash when the traction control system is limiting
wheel spin. SeeTraction Control System (TCS)
Warning Light on page 3-64andStabiliTrak
®Indicator
Light on page 3-64for more information. 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 3-16orAdaptive Cruise Control on page 3-19
for more information.The SERVICE TRACTION CONTROL message, the
traction control system warning light and the StabiliTrak
®
warning light will come on to let you know if there is a
problem with the traction control system. SeeDIC
Warnings and Messages on page 3-76.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
You can turn the system on or off at any time by
pressing the traction control system button located on
the console or on the end of the column shifter. The DIC
will display TRACTION CONTROL OFF when you
press the button.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information.
4-9

Magnetic Ride Control
Your vehicle may have a feature called Magnetic Ride
Control that automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response. If the
controller detects a problem within the system, the
DIC will display a SERVICE SUSPENSION SYS
message. SeeDIC Warnings and Messages on
page 3-76for more information. If this message appears,
have your vehicle serviced at your dealership.
Electronically Controlled Air Ride
Suspension
If you have a Cadillac Professional Vehicle, you may
have a feature called Electronically Controlled Air
Suspension. Air ride control is achieved through a
computer used to control and monitor the system. The
controller receives input from two height sensors to
determine the proper system response. If the controller
detects a problem with the system, the Driver
Information Center (DIC) will display a SERVICE
SUSPENSION SYS message. If this message appears,
have your vehicle serviced at your dealership.
StabiliTrak®System
Your vehicle may have this feature. The StabiliTrak®
system is an advanced computer controlled system that
helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power.
The StabiliTrak
®system comes on automatically
whenever you start your vehicle. The system cannot be
turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system and
StabiliTrak
®warning light on the instrument panel
cluster will be on after rst driving the vehicle and
exceeding 30 mph 48 (km/h) for 30 seconds. The
StabiliTrak
®system is off until the light has turned off.
This could take up to 15 minutes.
The traction control system and StabiliTrak
®warning
light on the instrument panel cluster will ash when the
system is operating. SeeTraction Control System
(TCS) Warning Light on page 3-64and
StabiliTrak
®Indicator Light on page 3-64for more
information. You may also feel or hear the system
working. This is normal.
4-10

The SERVICE STABILITRAK message will be displayed
and the traction control system and StabiliTrak®warning
light on the instrument panel cluster will come on if there
is a problem with the system. When this light and the
SERVICE STABILITRAK message are on, the system is
not operational. Adjust your driving accordingly.
Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking. If the
system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver to
maintain brake application. When this happens the brake
pedal will feel easier to push. Just hold the brake pedal
down rmly and let the system work for you. You may feel
the brakes vibrate, or you may notice some noise but this
is normal. The brakes will return to normal operation after
the brake pedal has been released.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Magnetic Speed Variable Assist
Steering System
This system continuously adjusts the effort you feel
when steering at all vehicle speeds. It provides ease
when parking, yet a rm, solid feel at highway speeds.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.
4-11

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 5-49.
