fuel CADILLAC CTS 2008 2.G User Guide

An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 5-9. The diagnostic system can
determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
If the vehicle has been driven through a deep
puddle of water, the vehicle’s electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run
as efficiently as designed and may cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one
full tank of the proper fuel to turn the light off.
SeeGasoline Octane on page 5-7.
If none of the above have made the light turn off,
your dealer/retailer can check the vehicle.The dealer/retailer has the proper test equipment
and diagnostic tools to x any mechanical or
electrical problems that might have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on or not working properly.
The 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 the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD system readiness, your dealer/retailer can
prepare the vehicle for inspection.

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for 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/RUN 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. SeeDIC Warnings and
Messages on page 3-56for more information.
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.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC is
also used to display warning/status messages.
All messages appear in the DIC display located at the
bottom of the instrument panel cluster. The DIC buttons
are located on the instrument panel, next to the
steering wheel.
The DIC comes on when the ignition is on. After a short
delay, the DIC displays the information that was last
displayed before the engine was turned off.
The top line of the DIC display shows the DIC
information. The bottom line of the DIC display shows
the compass. The compass displays in the trip/fuel
menus and in some vehicle information menus.
If a problem is detected, a warning message appears
on the display. Take any message that appears on
the display seriously and remember that clearing
the message only makes the message disappear,
and does not correct the problem.
DIC Operation and Displays
The Driver Information
Center (DIC) has different
displays which can be
accessed by pressing the
DIC buttons located on
the instrument panel, next
to the steering wheel.
3Trip/Fuel:Press this button to scroll through the
trip and fuel displays. See “Trip/Fuel Display Menu
Items” following for more information on these displays.

Trip/Fuel Display Menu Items
3
(Trip/Fuel):The following display menu items can
be displayed by pressing the trip/fuel button:
Odometer
This display shows the distance the vehicle has been
driven in either miles (mi) or kilometers (km).
Trip A or Trip B
These displays show the current distance traveled since
the last reset for each trip odometer in either miles (mi)
or kilometers (km). Both odometers can be used at
the same time. Each trip odometer can be reset to zero
separately by pressing and holding the set/reset button
for a few seconds while the desired trip odometer is
displayed.
Fuel Range
This display shows the approximate number of
remaining miles (mi) or kilometers (km) you can drive
without relling the fuel tank. This estimate is based
on the current driving conditions and changes if the
driving conditions change. For example, if you are
driving in traffic and making frequent stops, the display
may read one number, but if you enter the freeway,
the number may change even though you still have the
same amount of fuel in the fuel tank. This is because
different driving conditions produce different fuel
economies. Generally, freeway driving produces better
fuel economy than city driving.
Once the range drops below about 30 miles (48 km)
remaining, the display shows Low Range.
If your vehicle is low on fuel, the Fuel Level Low
message displays. See “Fuel Level Low” under
DIC Warnings and Messages on page 3-56for more
information.

the fuel economy that the vehicle has right now
and changes frequently as driving conditions change.
Unlike average economy, this display cannot be reset.
AVG (Average) Speed
This display shows the average speed of the vehicle
in either 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 display. To reset this display to zero, press the
set/reset button.
Speedometer
