DESCRIPTION AND OPERATION
Description
General
The interior mirror incorporates either manual or automatic dimming and has the security system alarm LED installed
on the underside of the mirror housing. Manual dimming is performed by rotating the cover of the alarm LED.
Automatic dimming is performed by electrochromic mirror glass.
On vehicles with a central door locking system operated by an infrared remote handset, the infrared receiver is also
incorporated into the mirror housing.
NAS vehicles all have automatic dimming and also incorporate a HomeLink® universal transmitter in the mirror
housing.
NOTE: HomeLink is a registered trademark owned by the Prince Corporation, Holland, Michigan, USA. Tel: 1–800–
355–3515.
The interior mirror is connected to the vehicle wiring by an electrical connector concealed by the finishers covering
the mounting stem. A permanent power feed from the passenger compartment fusebox supplies the alarm LED and,
where fitted, the infrared receiver, which are controlled by the Body Control Unit (BCU). When the ignition switch is in
position II, a second power feed, also from the passenger compartment fusebox, supplies the electrochromic mirror
circuits and the universal transmitter.
