Air Conditioner (Option)

While the engine and the air conditioner are running, be sure not to touch the rotating objects (fan belt, etc.).

Do not disconnect the piping of the air conditioner carelessly. To replenish refrigerant gas, do not use an improper method.

Touching the air conditioner’s piping is dangerous since it is filled with high-pressure refrigerant gas. Anyone other than qualified persons must not touch the piping.
