• Never use daytime running lights to see where you are going.
They are not bright enough and will not let you see far enough ahead for safety , espe cially at dusk or when it is dark. Always
switch on the low beams at dusk or when it is dark .
• Automatic headlights are only intended to assist the driver .
They do not relieve the driver of his responsibility to check the headlights and to turn them on manually according to the current
light and visibility conditions. For example , fog and rain cannot be
detected by the light sensors . So always switch on the headlights
under these weather conditions and when driving in the dark
tD .
• Crashes can happen when you cannot see the road ahead and
when you cannot be seen by other motorists.
-Always turn on the headlights so that you can see ahead and
so that others can see your car from the back.
