When Driving
Switches and Controls
NOTE
The headlights, other exterior lights and instrument panel illumination may not turn
off immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traf c jams inside tunnels, or in indoor parking
lots.
In this case, the lights turn off if the light switch is turned to the position.
When the headlight switch is in the position and the ignition is switched to ACC
or the ignition is switched off, the headlights, other exterior lights and instrument panel
illumination will turn off.
The instrument panel illumination can be adjusted by rotating the knob in the
instrument cluster. Also, the antidazzle mode can be changed by rotating the knob until
a beep sound is heard. To adjust the brightness of the instrument panel illumination:
Refer to Instrument Panel Illumination on page 4-28 .
The sensitivity of the AUTO lights may be changed by an Authorised Mazda Repairer.
Refer to Personalisation Features on page 9-10 .
