Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
■When cleaning the inside of the windshield (vehicles with LKA [Lane-Keeping
Assist])
