2007 CADILLAC CTS V fuel

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.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is
possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 337.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the
light off.
210

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.

Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is
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.
215

One-to-Four Shift Message
(CTS-V Only)
This message indicates
that you can only shift
from FIRST (1) to
FOURTH (4) instead of
FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to
turn off this feature. This helps you get the
best possible fuel economy.
After shifting to FOURTH (4), you may downshift
to a lower gear if you prefer.
SeeManual Transmission Operation on page 126
for more information.
Notice:Forcing the shift lever into any gear
except FOURTH (4) when the 1 TO 4 SHIFT
message comes on may damage the
transmission. Shift only from FIRST (1) to
FOURTH (4) when the light comes on.
Driver Information Center (DIC)
The DIC gives you the status of many of your
vehicle’s systems. It is also used to display driver
personalization features and warning/status
messages. All messages will appear on the audio
system display.
If your vehicle has the Base audio system, use the
information contained in this manual for
instructions on operating the DIC for your vehicle.
If your vehicle has the Navigation system, see
the Navigation system manual for instructions on
operating the DIC for your vehicle.

Vehicle Information Menu Item
Descriptions
The following paragraphs contain a more detailed
description of each menu item:
OUTSIDE TEMP:If you select this item, the
current outside temperature is displayed at the top
of the screen. It will be in either degrees
Fahrenheit (°F) or degrees Celsius (°C) depending
upon whether the system is set for English or
metric units. If you wish to change the units, see
DIC Main Menu on page 228.
MI TRIP A and B (KM TRIP A and B):For
information on the trip odometers, seeTrip
Odometers on page 200.
MILES RANGE (KM RANGE):If you select this
item, the approximate number of remaining
miles or kilometers you can drive without refueling
is displayed. This estimate is based on the
current driving conditions and will change if the
driving conditions change. For example, if you are
driving in traffic making frequent stops, the
display may read one number, but if you enter the
freeway, the number may change even thoughyou still have the same amount of gas in the gas
tank. This is because different driving conditions
produce different fuel economies. Generally,
freeway driving produces better fuel economy than
city driving.
If your vehicle is low on fuel, the Fuel Level Low
message will be displayed. See “Fuel Level
Low” underDIC Warnings and Messages on
page 232for more information.
MPG AVG (L/100 KM AVG):If you select this
item, the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km)
is displayed. This number is calculated based
on the number of mpg (L/100 km) recorded since
the last time this menu item was reset.
To reset the MPG AVG (L/100 KM AVG), press
the CLR button located to the right of the screen.
The display will return to zero.
MPG INST (L/100 KM INST):If you select this
item, the current fuel economy is displayed. This
number reects only the fuel economy that the
vehicle has right now and will change frequently as
driving conditions change. Unlike average fuel
economy, this menu item cannot be reset.
225

GAL FUEL USED (L FUEL USED):If you select
this item, the number of gallons or liters of fuel
used since the last reset of this menu item
is displayed.
To reset GAL FUEL USED (L FUEL USED), press
the CLR button located to the right of the screen.
The display will return to zero.
AVG MPH (AVG KM/H):If you select this item,
the average speed of the vehicle is displayed
in miles per hour (mph) or kilometers per
hour (km/h). This average is calculated based on
the various vehicle speeds recorded since the
last reset of this menu item.
To reset AVG MPH (AVG KM/H), press the
CLR button located to the right of the screen.
The display will return to zero.
TIMER:If you select this item, a timing feature is
displayed. The timer functions like a stopwatch
in that you can record the time it takes to
travel from one point to another.
To turn on the timer, press the CLR button located
to the right of the screen once. The display will
read 00:00:00 TIMER ON and begin counting.To turn off the timer, press the CLR button again.
When the timer is off, the display will show the

will stop.
To reset the timer, turn off the timer and then
press and hold the CLR button. The display will
return to zero.
BATTERY VOLTS:If you select this item, the
current battery voltage is displayed. If the voltage
is in the normal range, the display will have
OK after it. For example, the display may read
13.2 BATTERY VOLTS OK.
If there is a problem with the battery charging
system, there are four possible DIC messages that
may be displayed. SeeDIC Warnings and
Messages on page 232for more information.
ENGINE OIL LIFE:If you select this item,
the percentage of remaining oil life is displayed.
