Chrysler 2004 PT Cruiser - Manual (Page 134)

20. Airbag Light
The light comes on and remains on for 6 to 8
seconds as a bulb check when the ignition switch
is first turned ON. If the light does not come on
during starting, stays on, or comes on while driving, have
the system checked by an authorized dealer.
21. Trac Off Light — If Equipped
The TRAC OFF light will illuminate momentarily as a
bulb check when the ignition switch is first turned ON. If
the light does not come on, have the system checked.
The light will also come on if:
• The Traction Control switch has been used to turn
the system off,
• There is an anti-lock system failure,
• There is a Traction Control system failure,
• The system has been automatically deactivated to
prevent damage to the brake system due to over-
heated brake temperatures.
NOTE: Extended heavy use of Traction Control may
cause the system to deactivate and turn on the TRAC
OFF Light. This is to prevent overheating of the brake
system and is a normal condition. The system will remain
disabled for about 4 minutes until the brakes have
cooled. The system will automatically reactivate and turn
off the TRAC OFF Light.
22. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position
before engine start. If the bulb does not come on when
turning the key from OFF to ON/RUN, have the condi-
tion checked promptly.
