Electronic PRNDL Display: Description and Operation
Upshift Light

DESCRIPTION

This lamp is used on most models equipped with manual transmission. 

OPERATION

The Upshift lamp is illuminated to inform the driver of ideal shift points, with improved fuel economy as the specific objective. When the light is
illuminated, the transmission should be shifted to the next highest gear, if driving conditions permit such an action.
