2004 Cadillac CTS/CTS-VOwner ManualM

THIRD (3):This position gives you more power. You
can use THIRD (3) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
If the shift lever is put into THIRD (3), the transmission
won’t shift into THIRD (3) until the vehicle is moving
slowly enough.
SECOND (2):This position gives you even more power
than THIRD (3). You can use it on very steep hills, or
in deep snow or mud. (If the shift lever is put in
SECOND (2), the transmission won’t shift into
SECOND (2) until the vehicle is going slowly enough).
FIRST (1):The transmission will automatically select
this gear when conditions indicate that more power
is needed. You cannot select this gear manually.
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.Shift Lock Release
(Automatic Transmission)
If your vehicle has a dead battery or a battery with low
voltage, you can still shift the vehicle into PARK (P)
and remove the ignition key. Use the following
procedure to release the shift lever:
1. Pull up on the rear part of the leather boot that
surrounds the shift lever.
2. Fold the boot upward to expose the mechanism
beneath the shift lever.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
That reading means the same thing as the warning
light – the engine coolant is very hot. SeeEngine
Overheating on page 5-31.
Tire Pressure Light (CTS-V)
This light will come on if
the system detects low
tire pressure.
This light will also come on for a bulb check when the
vehicle is started.
SeeTire Pressure Monitor System (CTS-V) on
page 5-70for more information.
For more information on the proper tire pressure,
seeLoading Your Vehicle on page 4-34. For more
information on your tires, seeTires on page 5-58. CTS shown,

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board Diagnostics
Second Generation) and is intended to assure that
emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The check engine light comes on to indicate that
there is a problem and service is required. Malfunctions
often will be indicated by the system before any
problem is apparent. This may prevent more serious
damage to your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may notbe as good, and your engine may not run as
smoothly. This could lead to costly repairs that
may not be covered by your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.

Tire Pressure
When the tire pressure is displayed you will see a
vehicle in the display. The numbers in each corner
represent the tire pressure for the corresponding tire.
The tire pressure will be displayed in psi or kPa.
If any of the tires are blinking on the vehicle in the
display, this means that the tire pressure in that tire is
either high or low. SeeTire Pressure Monitor System
(CTS-V) on page 5-70for more information.
Lateral Acceleration
Lateral acceleration is a measure of how hard you are
taking a corner. For example, when you are turning right
you will feel your body push to the left. This force is
measured in a “g”. This gage will display from 0.00 g to
1.2 g. The lowest reading means there is no lateral
acceleration. The highest reading means the force the
driver is feeling is 1.2 times the acceleration due
to gravity.
When the lower button on the outboard switch is
pressed and held while the Lateral Acceleration display
is being shown, the peak hold values—both tick
marks and numbers—will be reset to zero.
Warning Messages
The warning messages that are described in the
following text are also shown in the tachometer display.
While any warning messages are shown, pressing
either button on the outboard switch will acknowledge
the warning and then display the gage relating to
the error message. For instance, if a tire is below the
minimum recommended pressure, the tire pressure
warning message will blink on and off (5 times for a
low tire warning, continuously for a at tire warning).
The driver can go to the tire pressure display
immediately by pressing either button on the
outboard switch.
3-56

Tire Pressure Warning Message
When you see this ashing
symbol, one or more of the
vehicle’s tires is either
under or over-inated.
To acknowledge this warning, press either button on the
outboard switch on the left spoke of the steering
wheel. There are three levels of warning for this display:
1. High Tire Pressure (above 42 psi (290 kPa))
2. Low Tire Pressure (below 25 psi (170 kPa))
3. Flat Tire (below 5 psi (35 kPa))For conditions 1 and 2, this warning will ash ve times
and the display will then show the tire pressure gage.
For condition 3, this warning will ash continuously until
the driver acknowledges it. In any of the three cases,
the warning will redisplay every 10 minutes until
the situation is corrected. Conditions 2 and 3 will also
display a warning light elsewhere on the cluster that will
stay illuminated after this warning is acknowledged.
SeeTire Pressure Light (CTS-V) on page 3-46for more
information. Also seeTire Pressure Monitor System
(CTS-V) on page 5-70for more information on tire
pressure specications.

Starting Disabled – Throttle Problem
This symbol appears
with the Starting
Disabled – Throttle
Problem message.
This message appears when your vehicle’s throttle
system is not functioning properly. Have your vehicle
serviced by your GM dealer.
Theft Attempted
This symbol appears
with the Theft
Attempted message.
This message is displayed if the content theft-deterrent
system has detected a break-in attempt while you
were away from your vehicle.
Top Speed – Fuel Cut Off
This symbol appears with
the Top Speed – Fuel Cut
Off message.
This message will appear when the Engine Control
Module (ECM) detects that the maximum speed for your
vehicle has been reached. Your vehicle’s top speed is
based on the top speed rating of the tires. This ensures
that your vehicle stays in a safe operating range for
the tires.

{CAUTION:
Drinking and then driving is very dangerous.
Your reexes, perceptions, attentiveness, and
judgment can be affected by even a small
amount of alcohol. You can have a serious — or
even fatal — collision if you drive after drinking.
Please do not drink and drive or ride with a
driver who has been drinking. Ride home in a
cab; or if you are with a group, designate a
driver who will not drink.
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. Also seeTraction Control
System (TCS) (CTS) on page 4-8orTraction Control
System (TCS) (CTS-V) on page 4-9.

Steering Tips
Driving on Curves
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) (CTS) on page 4-8orTraction Control
System (TCS) (CTS-V) on page 4-9.
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.
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.
4-13

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.Remember: Any traction control system helps avoid only
the acceleration skid. If your traction control system is
off, then an acceleration skid is also best handled
by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including engine braking by shifting to a
lower gear. Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow
on the road to make a mirrored surface — and
slow down when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
