Precautions to Handle Retractable Power Door MirrorsBIS0010G

Do not manually operate retractable power door mirrors. If mirror
is operated manually, be sure to use the retracting switch to
move mirror fully to the opposite direction until it stops. In this
case, a loud click sound is heard, but it is not abnormal. (If mirror
body is manually moved to the neutral position, door mirror will
have some disturbing symptoms during driving, including vibra-
tion, rough retracting movement, or sometimes no retracting.)
CAUTION:
Tilting mirror body forward with excessive force may dam-
age it.

When operating retracting switch to move mirror from the neu-
tral position to the fully-closed (backward limit) position, at the
beginning of the movement a faint click sound is heard, but it is not abnormal.

RH and LH retractable power door mirror bodies have different mounting angles in the neutral position.
This is why the RH mirror body delays slightly when operated with the retracting switch.
NOTE:

When the retractable power door mirror body is in the neutral
position, if retracting switch is operated to the opening direc-
tion while pressing it forward, mirror body is moved to the for-
ward limit position, but it is not abnormal. In this case, be sure
to operate retracting switch to move mirror to the fully-closed
(backward limit) position.

When the retracting switch is operated continuously 5 times
or more, the retractable power door mirror may be inactivated
to prevent overheating. In this case, wait for approximately 5
minutes to recover.
