brakes CADILLAC CTS V 2007 1.G Owners Manual

Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
You must fully apply your regular brakes rst
and then press the shift lever button before you
can shift from PARK (P) when the ignition key is
in ON. If you cannot shift out of PARK (P),
ease pressure on the shift lever and push the shift
lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear.
SeeShifting Out of Park (P) on page 132.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
REVERSE (R):Use this gear to back up.
At low vehicle speeds, you can also use
REVERSE (R) to rock your vehicle back and forth
to get out of snow, ice, or sand without damaging
your transmission. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 320for
additional information.NEUTRAL (N):In this position, the engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
You can also use NEUTRAL (N) when your
vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.
123

DRIVE (D):This position is for normal driving.
It provides the best fuel economy for your vehicle.
If you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more,
push the accelerator all the way down.
The transmission will shift down to a lower gear
and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 303
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only
the accelerator pedal may damage the
transmission. If you are stuck, do not spin
the tires. When stopping on a hill, use
the brakes to hold the vehicle in place.
Driver Shift Control (DSC)
Notice:If you drive your vehicle at high RPMs
without upshifting while using Driver Shift
Control (DSC), you could damage your
vehicle. Always upshift when necessary while
using DSC.
Your automatic transmission has a Driver Shift
Control (DSC) feature that allows you to change
gears similar to a manual transmission. To use the
DSC feature:
1. Slide the shift lever over from DRIVE (D) to
the right into the DSC area.
The sport mode light in
the instrument panel
cluster will come on.
If you do not move the shift lever forward or
rearward, the vehicle will be in sport mode.
When you are in the sport mode the
vehicle will still shift automatically.
124

Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
the light will come
on when your engine is
started and stay on
for several seconds.
This is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the anti-lock
portion of the brake system. If the brake system
warning light is not on, you still have brakes,
but you do not have anti-lock brakes. SeeBrake
System Warning Light on page 205for more
information.
If the light stays on, turn the ignition to OFF. If the
light comes on when you are driving, stop as
soon as possible and turn the ignition off. Then
start the engine again to reset the system. If
the light still stays on, or comes on again while
you are driving, your vehicle needs service.If the regular brake system warning light is not on,
you still have brakes, but you do not have
anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 205for more information.
The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
If the TC (traction
control) warning light
comes on and stays on,
there may be a
problem with the traction
control system.

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. SeeTraction
Control System (TCS) (CTS) on page 293or
Traction Control System (TCS) (CTS-V) on
page 295.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 332.
Braking
SeeBrake System Warning Light on page 205.
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 the brakes; the weight of the vehicle;
and the amount of brake force applied.
290

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 may not have
time to cool between hard stops. The 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 vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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 332.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 the 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 the
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 206.
291

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, the computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
292

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 the 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 the anti-lock pump or motor operate, and feel
the brake pedal pulsate, 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)
(CTS)
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 brakes the spinning wheel(s) and/or
reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
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 206. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.
293

Traction Control System (TCS)
(CTS-V)
Your vehicle has 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 brakes the spinning wheel(s)
and/or reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal.
This warning light will
come on to let you
know if there’s a
problem with your
traction control system.
SeeTraction Control System (TCS) Warning Light
on page 206. 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. Additionally, turning the
traction control system off on some surfaces, such
as deep snow and loose gravel, will assist vehicle
motion at lower speeds. SeeRocking Your Vehicle
to Get It Out on page 321andIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 320for
more information. See alsoWinter Driving on
page 316for information on using TCS when
driving in snowy or icy conditions.
You can turn the system
off by pressing the
TC (traction control)
button located on
the steering wheel.
295

Limited-Slip Rear Axle
If your vehicle has this feature, 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
Your vehicle may have an electronic stability
control system called StabiliTrak®.Itisan
advanced computer controlled system that assists
you with directional control of the vehicle in
difficult driving conditions.
StabiliTrak
®activates when the computer senses
a discrepancy between your intended path
and the direction the vehicle is actually traveling.
StabiliTrak
®selectively applies braking pressure
at any one of the vehicle’s brakes to help steer the
vehicle in the direction which you are steering.
When the system activates, a Stability System
Engaged message will be displayed on the
Driver Information Center. SeeDIC Warningsand Messages on page 232. You may also hear
a noise or feel vibration in the brake pedal.
This is normal. Continue to steer the vehicle in the
direction you want it to go.
If there is a problem detected with StabiliTrak
®,
a Service Stability System message will be
displayed on the Driver Information Center.
SeeDIC Warnings and Messages on page 232.
When this message is displayed, the system is not
operational. Driving should be adjusted accordingly.
StabiliTrak
®comes on automatically whenever
you start your vehicle. To help assist you with
directional control of the vehicle, you should always
leave the system on. You can turn StabiliTrak
®off if
you ever need to through the TC (traction control)
on/off button. SeeTraction Control System (TCS)
(CTS) on page 293orTraction Control System
(TCS) (CTS-V) on page 295.
If your vehicle is in cruise control when the
StabiliTrak
®activates, the cruise control will
automatically disengage. When road conditions
allow you to safely use it again, you may reengage
the cruise control. SeeCruise Control on
page 176for more information.
