Rearview mirror
Auto-dim function
An integrated sensor reacts to headlights from
following traffic and automatically reduces
glare.
Rearview mirror with compass (option)
The upper right-hand corner of the rearview
mirror has an integrated display that shows the
compass direction toward which the car is
pointing. Eight different directions can be dis-
played:
N , NE , E , SE , S , SW , W and NW . The
display shows your car's orientation with
respect to true north.
Calibrating the compass
The earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. A "
C " will be displayed if cali-
bration becomes necessary.
To calibrate the compass:
1. Stop the car in a large, open area, away
from traffic.
2. Using a pen or similar object, hold the button
(1) depressed for at least 6 seconds. " C " will
be displayed.
