| The door control units read the position of the corresponding mirror adjustment switches. The switch is voltage-coded; an A/D channel is used for each corresponding direction of adjustment (up or down, left or right) and for each mirror selection function (driver/passenger side mirror, fold-in, zero position). The voltage on the switches is always determined correctly (between 6 V and 16 V). |
| The mirror heating is activated via a semi-conductor. The output is short-circuit-proof. To switch on the mirror heating, turn the adjustment switch to the centre position. Depending on the outside temperature, the mirrors' surfaces are heated until the ignition is switched off (even if the rotary switch is no longer in the centre position). |
| Via the CAR menu of the MMI or the sound system, the driver can set whether the exterior mirrors are folded in automatically or not when the vehicle is locked. Accordingly, the exterior mirrors automatically move back into the original position when the ignition is switched on. |
| The fold-in/out function is operated by turning the joystick switch (adjustment switch for mirror with fold-in feature -E168-). When the switch is turned to the "fold-in" position, the mirrors will immediately move to the parking position. |
| Tilting function of exterior mirror on passenger's side |
| The tilting function is only available in vehicles fitted with the memory for exterior mirrors. When the reverse gear is engaged, the mirror will tilt downwards slightly if the system is set to the exterior mirror on the passenger side. This enables the driver to see the kerb when parking. |
| The mirror moves back into its original position as soon as the reverse gear is disengaged and the vehicle's speed reaches approx. 15 km/h. In addition, the mirror also moves back into position if the system is switched back to the exterior mirror on the driver side or the ignition is switched off. |
| If the position of the mirror's surface is changed while the mirror is tilted downwards, this new position is automatically stored and assigned to the remote control key when the reverse gear is disengaged. |
| Automatic anti-dazzle function |
| The automatic anti-dazzle function is optional and is listed as such in the coding. The light sensor, which is fitted in the interior mirror, passes on the signal to activate the anti-dazzle function to the automatic anti-dazzle exterior mirrors (the signal is only looped through the front door control units). |
| The exterior mirrors are dimmed automatically together with the anti-dazzle interior mirror. When the ignition is switched on, the mirrors are dimmed automatically depending on the incidence of light (e.g. from the headlights of a vehicle travelling behind). |
| When the interior lights are switched on and reverse gear is engaged, the system returns the mirrors to the original setting (not dimmed). |
| If the automatic anti-dazzle function of the interior mirror is switched off, the automatic anti-dazzle function of the exterior mirrors is also deactivated. |
| The mirror memory is only fitted in conjunction with seats with memory function. Both systems are programmed and called up via a switch control panel in the driver door. In vehicles with the memory function for the driver seat, the settings for the exterior mirrors are automatically stored when the seat position is stored. |
| The turn signal repeaters have been designed with Light Emitting Diodes and are fitted in the housing of the the exterior mirrors. If one of the LEDs in the turn signal repeater is defective, the turn signal in the exterior mirror must be replaced completely. The turn signal repeaters are activated via the corresponding front door control unit. |
