In vehicles with a rain sensor, the wipers turn on in the rain once the vehicle speed exceeds ap­
proximately 2 mph (4 km/h). The higher the sen­
sitivity of the rain sensor that is set (switch
@ to
the right), the earlier the w indshield w ipers react
to moisture on the windshield . You can deacti­
vate the rain sensor mode in the Infotainment
system, wh ich switches the intermittent mode
on. To do this, select :
I MENU I button> Vehicle>
