.Check that good quality fuel is
used. 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, misfiring,
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 may require at least one full tank
of the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑47.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel to the next to the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when the ignition is turned to ON/RUN
while the engine is off. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or 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 II
system readiness, your dealer
can prepare the vehicle for
inspection.

Antilock Brake System
(ABS) Warning Light
The Antilock Brake System (ABS),
this light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. A chime may also sound when
the light comes on steady. If this
happens, start the engine again to
reset the system. If the ABS light
stays on, or comes on again while driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes.
If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light on
page 5‑22.

Information Center (DIC), see Driver
Information Center (DIC) on
page 5‑27 for all brake-related DIC
messages.
Up-Shift Light
The vehicle may have an up-shift
light. It indicates when to shift to the
next higher gear for best fuel
economy. See
Manual Transmission on
page 9‑29 for more information.
For the CTS-V, the tracer lights
function as a performance up-shift
light.
The tracers flash to indicate when to
shift to the next higher gear to avoid
the engine speed limit. See

System (TCS) indicator/warning
light comes on briefly when the
engine is started. If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally,
the indicator light turns off.
If the light is on and not flashing, the
TCS, and potentially the StabiliTrak
system have been disabled. A DIC
message may display. Check the
DIC messages to determine which
feature(s) is no longer functioning
and whether the vehicle requires
service.
If the indicator/warning light is on
and flashing, the TCS and/or the
StabiliTrak system is actively
working.

Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. SeeTire Messages on
page 5‑43. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10‑66. When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See
Tire Pressure Monitor
Operation on page 10‑69.
Engine Oil Pressure Light
Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on, have the
vehicle serviced by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.

BATTERY VOLTS LOW
This message displays when the
electrical system is charging less
than 10 volts or the battery has
been drained.
If this message appears
immediately after starting the
engine, it is possible that the
generator can still recharge the
battery. The battery should recharge
while driving, but may take a few
hours to do so. Consider using an
auxiliary charger to boost the
battery after returning home or
arriving at a final destination. Make
sure you follow the manufacturer's
instructions.
If this message appears while
driving or after starting the vehicle
and stays on, have it checked
immediately to determine the cause
of this problem.
To help the generator recharge the
battery quickly, reduce the load on
the electrical system by turning off
the accessories.The normal battery voltage range is
11.5 to 15.5 volts. Monitor battery
voltage on the DIC by pressing the
vehicle information button until
Battery Voltage is displayed.
SERVICE BATTERY
CHARGING SYSTEM
This message displays when there
is a problem with the generator and

so. Have the electrical system
checked by your dealer. Under
certain conditions, the charging
system light may also turn on in the
instrument cluster. See
