WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operat ion in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers (vehicles with outside rear view mirror defoggers) are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on. (vehicles with wind-
shield wiper de-icer)
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

■Circling calibration
When “C” appears on the dis-
play, drive the vehicle at 5 mph
(8 km/h) or less in a circle until
a direction is displayed.
If there is not enough space to
drive in a circle, drive around the
block until the direction is dis-
played.
■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
● The vehicle is on an inclined surface.
● The vehicle is in a place where the earth’s magnetic field is subject to inter-
ference by artificial magnetic fiel ds (underground car park/parking lot, under
a steel tower, between buildings, roof car park/parking lot, near an intersec-
tion, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
● The battery has been disconnected.
● A door is open.
WARNING
■While driving the vehicle
Do not adjust the display. Adjust the display only when the vehicle is
stopped.
■ When doing the circling calibration
Secure a wide space, and watch out for people and vehicles in the vicinity.
Do not violate any local traffic rules while performing circling calibration.
