Instruments and Controls 5-13 Charging System Light If a short distance must be driven with the light on, be sure to turn off all accessories, such as the radio and air conditioner. Malfunction Indicator Lamp The charging system light comes on briefly when the ignition is turned on, but the engine is not running, as a check to show the light is working. The light turns off when the engine is started. If it does not, have the vehicle serviced by your dealer. If the light stays on, or comes on while driving, there could be a problem with the electrical charging system. Have it checked by your dealer. Driving while this light is on could drain the battery. A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors the operation of the vehicle to ensure emissions are at acceptable levels, helping to maintain a clean environment. The malfunction indicator lamp comes on when the vehicle is placed in ON/RUN for key access or Service Only Mode for keyless access, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. See Ignition Positions (Key Access) on page 9‑14 or Ignition Positions (Keyless Access) on page 9‑17 for more information. If the malfunction indicator lamp comes on while the engine is running, this indicates that the OBD II system has detected a problem and diagnosis and service might be 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 also assists the dealer technician in correctly diagnosing any malfunction.
