Rear View Mirrors
Auto-dimming Interior Mirror
When the ignition is switched on the auto-dimming
interior mirror will darken automatically depending
on the amount of light shining into the vehicle
through the rear window glass. The auto-dimming
feature will turn off when reverse gear is selected.
The auto-dimming feature on the interior rear view
mirror will not operate correctly if light through the
rear window glass is obstructed.
Exterior Mirror Foldback Relay
NOTE: On left-hand drive vehicles, the exterior
mirror foldback relay is positioned on the left–hand
side of the vehicle under the rear seat cushion. On
right-hand drive vehicles, the exterior mirror
foldback relay is positioned on the right–hand side
of the vehicle under the rear seat cushion.
To gain access to the exterior mirror foldback relay,
the C-pillar lower trim panel and the rear scuff plate
trim panel must be removed to allow the carpet to
be detached from the floor panel.
