eMotor Overspeed Feature
Caution: Failure to heed overspeed warnings may result in damage to the bearings and transmission of the vehicle, as well as potential damage to property, or personal injury.
This feature aims to prevent the motor speed from exceeding a series of thresholds by limiting power to the motor and presenting messages of increasing severity to the driver, instructing them to apply the service brakes.
If the eMotor's speed reaches the first threshold, power to the motor is reduced to slow the vehicle. If the truck is going downhill in manual mode, and is in first gear, the eMotor speed may still increase.
If the eMotor's speed reaches the motor's maximum limit, an amber caution appears, instructing the driver to apply the service brakes. See Fig.. Do not rely on recuperative braking to slow the vehicle at this point.

This caution can be dismissed by pressing the back button on the left-hand switch pod.
If the eMotor's speed exceeds the motor's limit, an acoustic alert activates and a red warning, as shown, see Fig..instructs the driver to apply the service brakes.
