CAUTION
Avoid activating the washer system when it is frozen or the fluid reservoir

Headlight washer*
To save washer fluid, the headlights are washed automatically according to a
defined interval when the headlights are on.
Reduced washing
When there is about 1 liter (1 qt) of washer fluid left in the reservoir and
the Washer fluid Level low, refill message is displayed in the instrument
panel together with the
symbol, the
washer fluid supply to the headlights is cut off. This is to prioritize windshield
cleaning and visibility through it. The headlights are only washed if high or low
beam is on.
