Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm).
For eAssist vehicles, when the ignition is in ON/RUN, the tachometer indicates the vehicle status. When pointing to AUTO, the engine is off but the vehicle is on and can move. The engine could auto start at any time. When the indicator points to OFF, the vehicle is off.
When the engine is on, the tachometer will indicate the engine’s revolutions per minute (rpm). The tachometer may vary by several hundred rpm’s, during auto stop mode, when the engine is shutting off and restarting.
A slight bump may be felt when the transmission is determining the most fuel efficient operating range.
