Tire Pressure Light (CTS-V Only)
If the vehicle has the Tire
Pressure Monitor System,
this light will come on if
the system detects low
tire pressure.
This light will also come on for a bulb check when the
vehicle is started.
See Tire Pressure Monitor System on page 5-68 for
more information.
For more information on the proper tire pressure, see
Loading Your Vehicle on page 4-32 . For more

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which monitors
operation of the fuel,
ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice: If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
