PRECAUTIONS

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

• Put a “CAUTION: FLAMMABLE” sign in the workshop.
  
• Be sure to work in a well ventilated area and furnish workshop with a CO₂ fire extinguisher.
