High Voltage Safety
Emergency Shutdown Procedure
In the event that the vehicle must be shut down immediately, bring the vehicle to a complete stop. While still pressing the service brake
pedal, enter Park Mode by engaging the park brake and then switch the ignition key to the “OFF” position. Ensure that the parking brake is
engaged and exit the vehicle safely.
High Voltage Manual Service Disconnects (MSD)
The high voltage battery system is equipped with two safety devices to disconnect the high
voltage current path. These devices are called Manual Service Dis-
connects (MSD). They should be left alone unless there is a good
reason to remove them.
To disconnect the high voltage batteries, isolating them from the
bus, follow these steps.
1. Disconnect the 12V battery (standard group 31) first by
removing the ground cable from the battery. The battery
compartment is located street side under driver’s window.
2. Remove the shunt portion (front cover) of each MSD
to disconnect the High Voltage. This can be done by
first pushing in on the orange locking tab centrally lo-
cated on the black locking handle. While the tab is in
the “in” or unlocked position, rotate the black locking
handle
down and forward
to the end of travel which
will be approximately 90° from the locked position.
