2006 CADILLAC XLR wheel

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.ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.

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
hear a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With ABS, 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)
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 one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system works the rear brakes and reduces engine
power to limit wheel spin.
The TRAC SYSTEM ACTIVE message will display on
the Driver Information Center (DIC) when the traction
control system is limiting wheel spin. SeeDIC Warnings
and Messages on page 3-67. 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
reengage the cruise control. SeeAdaptive Cruise
Control on page 3-15orCruise Control on page 3-12
for more information.

This warning light will
come on to let you know
if there is a problem
with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-56. When this warning light is 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 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 5-32andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 5-32
for more information.To turn the system off,
press the front part of
the traction control button
located on the center
console.
The TRACTION SYSTEM-OFF message will display on
the DIC and the traction control system warning light
will come on. If the system is limiting wheel spin when
you press the button, the TRACTION SYSTEM-OFF
message will display — but the system will not turn off
right away. It will wait until there is 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 SYSTEM-ON message
should display briey on the Driver Information Center.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 6-3for more information.

Magnetic Ride Control
Magnetic Ride Control 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 RIDE
CONTROL message. SeeDIC Warnings and Messages
on page 3-67for more information. See your dealer
for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works
like a standard axle most of the time, but when one
of the rear wheels has no traction and the other
does, this feature will allow the wheel with traction
to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a 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.
When you rst start your vehicle and begin to drive
away (6 mph (10 km/h)), especially during cold weather,
the message STABILITRAK WARMING may be
displayed in the Driver Information Center (DIC), the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The
StabiliTrak
®System performance is affected until the
message, STABILITRAK READY, is displayed in
the DIC. This can take up to 15 minutes.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph (30 km/h)
for 10 seconds if the steering is not centered.
The system is off until the STABILITRAK ACTIVE
message is displayed.

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
Your vehicle is equipped with a steering system that
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.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do
their work where the tires meet the road. Adding the
sudden acceleration can demand too much of those
places. You can lose control. SeeTraction Control
System (TCS) on page 5-9.
What should you do if this ever happens? Ease up
on the accelerator pedal, steer the vehicle the way
you want it to go, and slow down.
5-13

Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions. Under
less favorable conditions you will want to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while your
front wheels are straight ahead.
Try to adjust your speed so you can “drive” through
the curve. Maintain a reasonable, steady speed.
Wait to accelerate until you are out of the curve, and
then accelerate gently into the straightaway.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 6-3.Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
nd 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.
You can avoid these problems by braking — if you can
stop in time. But sometimes you cannot; there is not
room. That is the time for evasive action — steering
around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes.
SeeBraking on page 5-6. It is better to remove as much
speed as you can from a possible collision. Then steer
around the problem, to the left or right depending on the
space available.
5-14

An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can turn
it a full 180 degrees very quickly without removing either
hand. But you have to act fast, steer quickly, and just as
quickly straighten the wheel once you have avoided
the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive
driving at all times and wear safety belts properly.
Off-Road Recovery
You may nd that your right wheels have dropped off the
edge of a road onto the shoulder while you are driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that your vehicle straddles the edge of
the pavement. You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
the pavement edge. Then turn your steering wheel
to go straight down the roadway.
5-15

Check your 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 inside mirror, activate your right lane change
signal and move back into the right lane. Remember
that your 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.
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.
