(12) Move both outer rear view mirror assemblies to the retract position.

(13) Press the retractable outer mirror switch.

(14) Check that both outer rear view mirror assemblies move from the retract position to the driving position.

(15) Move both outer rear view mirror assemblies to the retract position.

(16) Move one of the outer rear view mirror assemblies to the driving position by hand.

(17) Press the retractable outer mirror switch.

(18) Check that the retracted outer rear view mirror assembly moves to the driving position.

(c) Check the operation of the outer rear view mirror assemblies according to retractable outer mirror switch operations and engine switch condition.

(1) When the outer rear view mirror assemblies are operating, turn the engine switch off and check that the mirror operation stops immediately.

(2) Turn the engine switch on (ACC) and press the retractable outer mirror switch. Check that the outer rear view mirror assemblies operate in the opposite direction.

(d) Check the operation of the outer rear view mirror assembly when it is blocked by an obstacle.

(1) When an outer rear view mirror assembly is moving to the retracted or driving position, block it by hand. Check that stops moving.

(2) With the outer rear view mirror assembly stopped partway, push the retractable outer mirror switch. Check that the outer rear view mirror assembly moves in the opposite direction.

(a) With the engine switch off and the retractable outer mirror switch in auto position, when the doors are unlocked through the entry function, wireless function or key-linked function, check that both outer rear view mirror assemblies move from the retract position to the driving position, and stop in the driving position.

(b) With the engine switch off and the retractable outer mirror switch in auto position, when the doors are locked through the entry function, wireless function or key-linked function, check that both outer rear view mirror assemblies move from the driving position to the retract position, and stop in the retract position.

(c) When the engine switch is on (ACC) and then turned off while the retractable outer mirror switch is in auto position, check that both outer rear view mirror assemblies automatically move from the driving position to the retract position.

(d) When the engine switch is off and then turned on (ACC) while the retractable outer mirror switch is in auto position, check that both outer rear view mirror assemblies automatically move from the retract position to the driving position.

CHECK REVERSE SHIFT-LINKED FUNCTION

(a) Turn the engine switch on (IG).

(b) Turn the mirror select switch L or R switch on.
