• To maintain the High Voltage battery, drive your vehicle for more than 30 minutes
at least once every three months.
If road conditions are not suitable or desirable for driving, the following alternate
procedure can be used to maintain the vehicle's High Voltage battery if local idling
by-laws permit:

2. Depress the brake pedal and press the ENGINE START/STOP button as you
normally would to start the vehicle.

of this 30-minute run.
