Water Management While Driving

When driving at a speed of 80 km/h (50 mph) or faster (depending on how heavy it is raining), drips can form along the side window. At higher speeds and when it is raining very heavily, more drips will accumulate until - in extreme cases - a flowing jet of water can form.

The water flowing back onto the side windows can leak into the passenger compartment at the point where the convertible top and top of the side window meet. Water management is designed so that the water on the inside of the hood cover and B-pillar seal flows down onto the B-pillar trim and runs off between the seat belt and B-pillar trim into the water drip tray.
