When Driving
Switches and Controls
Auto-light control
When the headlight switch is in the
sensor senses the surrounding lightness or darkness and automatically turns the headlights,
other exterior lights and instrument panel illumination on or off (see chart above).
Do not shade the light sensor by adhering a sticker or a label on the windscreen.
Otherwise the light sensor will not operate correctly.
The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windscreen when the wiper lever is in the
ignition is switched ON as ngers could be pinched or the wipers and wiper blades
damaged when the wipers activate automatically. If you are going to clean the
windscreen, be sure the wipers are turned off completely — this is particularly
important when clearing ice and snow — when it is particularly tempting to leave the
engine running.
