What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is running, the light will either stay on or flash de-
pending on the nature of the problem. Cycle the ignition key when the vehicle is safely and
completely stopped and the transmission is placed in the PARK position. The light should
turn off. If the light remains on with the engine running, your vehicle will usually be driv-
able; however, see an authorized dealer for service as soon as possible.
If the light continues to flash when the engine is running, immediate service is required and
you may experience reduced performance, an elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on when the ignition is first placed in the
MAR (ACC/ON/RUN) position and remain on briefly as a bulb check. If the light does not
come on during starting, have the system checked by an authorized dealer.
