In cars with an automatic transmission, the indicator lamp switches on when the SPORT button on the selector lever is pressed. The sport function can be activated when the selector is in position D or N.

In SPORT mode, the transmission remains longer in each gear.

The lamp is supplied with current in the main instrument unit and grounded by the main instrument unit control module. The TCM continuously sends bus information SPORT, unit ON/OFF.

On receiving SPORT ON, the control module grounds the output of the lamp which then lights up.

The indicator lamp goes out under the following conditions:

• When the sport button is depressed again.
• When the transmission is in Limp-home mode.
• When Winter mode is selected.
• If the ignition is turned off and then on again.
• The selector lever is moved to P or R.
