DescriptionThe two external rearview mirrors are adjusted by the control on the driver's door armrest, illuminated when the side lights are on. The two mirrors are adjusted by a single button pressed in the four directions: a switch selects the right or left mirror.The button, which can be pressed in four directions, controls two electric motors located in each of the two mirrors: one motor rotates the mirror on a horizontal axis, while the other on a vertical axis.The circuit for adjusting and folding the external rearview mirrors is protected by a fuse located in the junction unit.The mirrors can only be adjusted and folded when the ignition is on.The electronic rearview mirror incorporates an electronic device which permits automatic operation of the anti-dazzle feature.The device can only operate when the ignition is on, and is protected by a fuse in the junction unit.The automatic anti-dazzle function is disabled when reverse gear is engaged.
Functional description The two-way switch controlling mirrors H31 operates electric motors located in the right and left electrically-operated door mirrors P60 and P61 respectively. The switch is supplied when the ignition is turned on (INT/A) from fuse line F5 of junction unit B1 to pins 1 and 4 of H31 , while pin 2 is earthed. The mirror is adjusted by operating the switch in one or other directions. Positive and earth signals are then sent to one of the two motors to determine the direction of rotation. The motors that govern vertical position are connected to pins 2 of connector A of mirrors P60 and P61 . The motors that govern horizontal position are connected to pins 3 of the same connectors. According to the selector position, either the left motors (output signals from pins 8 and 9 of control H31 ) or the right motors (output signals from pins 7 and 10 of H31 ) are connected; the common supply comes from pin 3 and is connected to pin 1 of connector A of P60 or P61 . The mirrors are folded down by operating mirror control switch H31 : pins 1 and 2 of connector D of P60 and P61 . they are connected respectively to pins 11 and 5, and pins 12 and 6 of mirror control H31 . Switch H31 is lit by ignition-operated power source (INT/A) from the line of fuse F5 of junction unit B1 . The electrochromatic interior rear view mirror P65 contains an electronic device that controls the mirror's automatic antiglare function. Device P65 is supplied by ignition-operated line (INT/A) of relay R1 protected by fuse F9 . When a reverse engagement signal ( 3309201SeeE2022REVERSING LIGHTS ) is received, the antiglare function is disabled.
