Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It makes sure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working.
If it does not come on, have the vehicle serviced by
your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a
required Emission Inspection/Maintenance test.
SeeAccessories and Modifications on page 5-3.

This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
The following can prevent more serious damage to
the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 5-8. 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 5-6.

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.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.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 3-58for 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.
3-49

Boost Gage
For the CTS-V, this gage is located in the instrument
panel cluster.
This gage indicates positive manifold pressure which is
the induction air pressure level in the intake manifold
before it enters the combustion chamber. This gage
reads zero under light throttle before boost is generated.
This gage automatically resets to zero every time the
engine is started.
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. United States

(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.
3-51

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 the vehicle is low on fuel, the Fuel Level Low message
displays. See “Fuel Level Low” underDIC Warnings
and Messages on page 3-58for more information.
AVG (Average) Economy
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number
of mpg (L/100 km) recorded since the last time this
display was reset. To reset this display to zero, press
the set/reset button.
Timer
This display can be used like a stopwatch. You can
record the time it takes to travel from one point to
another. To access the timer, press the trip/fuel button
until Timer 00:00:00 displays.
To turn on the timer, press the set/reset button until the
timer starts.
To turn off the timer, press the set/reset button again.
The timer stops and displays the end timing value.
To reset the timer to zero, press and hold the set/reset
button after the timer has been stopped.
Inst (Instantaneous) Economy
This display shows the current fuel economy in either
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). This number reects only 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.
