CADILLAC CTS 2007 1.G Owners Manual

Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 334. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.If your vehicle has this
light, it will come on
when there is a problem
with your engine oil
pressure.
This light will come on when you turn your key to
ON or START. It goes off once you start the
engine. That is a check to be sure the light works.
If it does not come on, be sure to have it xed
so it will be there to warn you if there is a problem.
When the light comes on and stays on, it means
that oil is not owing through your engine properly.
You could be low on oil and you might have
some other system problem. SeeEngine Oil on
page 346for more information.
212

Sport Mode Light
(Automatic Transmission/CTS)
This light will come on
while the sport mode is
in use.
When you turn off the sport mode, the light will go
out. If it stays on, your vehicle may need service.
See your dealer. See “Sport Mode” under
Automatic Transmission Operation on page 122
for more information.

regarding this light, see
Theft-Deterrent
System on page 111.
Fog Lamp Light
This light will come on
when the fog lamps are
in use.
The light will go out when the fog lamps are
turned off. SeeFog Lamps on page 183for more
information.
Lights On Reminder
This light comes on
whenever the parking
lamps are on.
SeeHeadlamps on Reminder on page 181for
more information.
213

turned off. SeeCruise Control on page 176for
more information.
Highbeam On Light
This light comes on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 172for more information.
Fuel Gage
The fuel gage shows
approximately how
much fuel is in the fuel
tank. It works only
when the ignition is in
the ON position.
If the fuel supply gets low, the Fuel Level Low
message will appear on the Driver Information
Center (DIC) and a single chime will sound. See
DIC Warnings and Messages on page 232for
more information.
214

Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the tank
than the gage indicated. For example, the gage
may have indicated that the tank was half full,
but it actually took a little more or less than half
the tank’s capacity to ll the tank.
Message Center
Message Center (CTS-V)
Your vehicle may have a message center that can
display information relating to powertrain uids, tire
pressures, vehicle dynamics, speedometer and
odometer information, and transmission status.
It also displays warning messages. There are
two different areas where message center
information will be displayed. One display is inside
of the tachometer and the other is inside of the
speedometer.These are the controls
for the message center.
They are located on
the left spoke of
the steering wheel.
The outboard switch (A and B) controls the display
of information inside of the tachometer. The
upper button (C) on the inboard switch controls
the display of information inside of the
speedometer. The lower button (D) on the inboard
switch turns the traction control on or off. See
Traction Control System (TCS) (CTS) on page 293
orTraction Control System (TCS) (CTS-V) on
page 295for more information.

Speedometer Display
This display will show information relating to
vehicle speed, odometer, and transmission status.
The information displayed can be changed by
pressing (C). Pressing this button cycles the
displayed information as follows: digital
speedometer only, odometer only, speedometer
and odometer, or blank display.
When the transmission is shifted into
REVERSE (R), an R will appear in the
upper right corner.
During slow speed maneuvers, the engine’s
computer may command the transmission to
engage the Skip Shift feature. For more
information seeManual Transmission Operation
on page 126.
Tachometer Display
Press (B) to cycle through the following displays:
coolant temperature, oil pressure, oil temperature,
transmission temperature, tire pressure, and
lateral acceleration. Press (A) to cycle through the
displays in reverse order. If you press (A), for
about one second, the display will become blank.
Coolant Temperature
When the coolant
temperature displays
you will see the coolant
temperature symbol.
The temperature displays in degrees Fahrenheit or
Celsius with a graph beneath the reading. If the
graph shows the temperature in the shaded
area all the way on the right, then the coolant
temperature is hot. SeeEngine Overheating
on page 360for more information.
216

Oil Pressure
When the oil pressure
displays you will see the
oil pressure symbol.
The oil pressure displays in psi or kPa with a
graph beneath the reading. If the graph shows the
pressure in the shaded area all the way to the
left, then the oil pressure is low. SeeEngine Oil on
page 346andDIC Warnings and Messages on
page 232for more information.
Oil Temperature
When the oil
temperature displays
you will see the oil
temperature symbol.The temperature displays in degrees Fahrenheit or
Celsius with a graph beneath the reading. If the
graph shows the temperature in the shaded
area all the way on the right, then the oil
temperature is hot. SeeEngine Oil on page 346
for more information.
Transmission Temperature
When the transmission
temperature displays
you will see the
transmission
temperature symbol.
The temperature displays in degrees Fahrenheit or
Celsius with a graph beneath the reading. If the
graph shows the temperature in the shaded
area all the way on the right, then the transmission
temperature is hot. SeeDIC Warnings and
Messages on page 232andManual Transmission
Fluid on page 354for more information.
217

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 on page 405for 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 (B) 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 (A) or (B) will acknowledge the warning
and then display the gage relating to the message.
For instance, if a tire is below the minimum
recommended pressure, the tire pressure warning
message will blink on and off (ve 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.
218

Transmission Fluid Hot Message
When you see this
ashing symbol, the
transmission uid
temperature is high
(290°F (143°C)).
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press this button, the
warning will redisplay every 10 minutes until the
temperature returns to the normal operating range.
If this message appears, you may continue to drive
at a slower speed while monitoring the transmission
uid temperature. Ideally, the transmission oil
temperature should not rise above 265°F (129°C). If
you regularly experience temperatures above this
limit due to high performance operation, it is
recommended to use an auxiliary uid cooler for the
transmission and differential. See your dealer for
details. If this warning is displayed during normal
vehicle operation on at roads, your vehicle may
need service. See your dealer for an inspection.
SeeDIC Warnings and Messages on page 232and
