2006 CADILLAC DTS brake light

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

The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy
rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the road,
and even people walking.
It is wise to keep your windshield wiping equipment in
good shape and keep your windshield washer uid
reservoir lled with washer uid. Replace your
windshield wiper inserts when they show signs of
streaking or missing areas on the windshield, or when
strips of rubber start to separate from the inserts.
{CAUTION:
Wet brakes can cause accidents. They will not
work as well in a quick stop and may cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water
or a car wash, apply your brake pedal lightly
until your brakes work normally.Driving too fast through large water puddles or even
going through some car washes can cause problems,
too. The water may affect your brakes. Try to avoid
puddles. But if you cannot, try to slow down before
you hit them.
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 reections
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.

Always clean the brake uid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake uid.
Notice:
Using the wrong uid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system parts so
badly that they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s painted
surfaces, the paint nish can be damaged. Be
careful not to spill brake uid on your vehicle. If
you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-86.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving, except when you are pushing on the
brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are rst applied or lightly
applied. This does not mean something is wrong with
your brakes.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on the other
vehicle. Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−) jump
starting terminal.The remote positive (+) terminal is located in the
engine compartment on the passenger’s side of the
vehicle. Lift the red plastic cap to access the
terminal. SeeEngine Compartment Overview on
page 5-12for more information on the location
of the remote positive (+) terminal.
A second remote positive (+) terminal is located on
the rear underseat fuse block.
The remote negative (−) terminal is located behind
the power steering pulley, near the engine cover.
It is marked GND (−). 4.6L LD8 Engine shown, 4.6L L37 Engine similar
