StabiliTrak®/Traction Control
System (TCS) Warning Light
The Traction Control
System (TCS)/StabiliTrak
warning light should
come on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the light comes on or stays on while driving, there
may be a problem with the TCS/StabiliTrak and the
vehicle may need service. When this warning light is on,
the system does not limit wheel spin. Adjust driving
accordingly.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the light comes on and stays on while driving, the
vehicle may have a problem with the cooling system.
Stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime sounds when this light is on.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the engine coolant overheats the engine coolant
temperature warning light will come on. SeeEngine
Overheating on page 5-37andEngine Coolant
Temperature Warning Light on page 3-41for more
information.
Tire Pressure Light
For vehicles with a tire
pressure light, this light
comes on briey when the
engine is started and
provides information about
tire pressures and the
Tire Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information Center
(DIC), can accompany the light. SeeDIC Warnings and
Messages on page 3-58for more information. Stop and
check the tires as soon as it is safe to do so. If a tire is
underinated, inate to the proper pressure. SeeTires on
page 5-61for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes for
about a minute and stays on steady for the remainder
of the ignition cycle. This sequence repeats with
every ignition cycle. SeeTire Pressure Monitor System
on page 5-71for more information. United States

Engine Oil Pressure Gage
For vehicles with an engine oil pressure gage. It shows
the engine oil pressure in psi (pounds per square inch)
when the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but if readings are outside
the normal operating range, the oil pressure light will
come on. SeeOil Pressure Light on page 3-46for more
information.A reading outside the normal operating range may be
caused by a dangerously low oil level or some other
problem causing low oil pressure. Oil should be
checked as soon as possible. See Oil pressure Low
Stop Engine underDIC Warnings and Messages
on page 3-58andEngine Oil on page 5-18.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States

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

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.
