Max Power mode
This is a Max Power Mode Indicator symbol. It belongs to the GMC Sienna electric vehicle (EV), which, when used, adjusts the acceleration pedal “map”. The symbol is a drawing that looks like Thor’s hammer with a lightning bolt inside.
- Before continuing, is one of these truly your symbol?? If yes, read on below.

Max Power mode provides maximum propulsion and is intended for short duration use. This is perhaps akin to various Sport Modes offered in internal combustion engine vehicles.
The mode is not intended for daily use. Engaging Max Power mode will not change an active drive mode but will provide additional propulsion torque for maximum acceleration.
It will not function when the vehicle battery charge is low and remaining in this mode will reduce the vehicle’s range.
