                 COOLANT

                 REPLACEMENT
                      CAUTION
                                                                                                                     61
                 Top up the refrigerant after adding some coolant.

                 Use the right refrigerant service systems designed for this model.

                 Since leakage is common in the A/C system, keep the workspace well ventilated.

                 Collect and dispose the coolant as required.


                 After collecting the refrigerant or replacing the A/C parts, refill the coolant.
