NOTICE
■Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alkaline solu-
tions, dye, bleach or other detergent. Doing so may discolor the vehicle interior or
cause streaks or damage to painted surfaces.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces.
●Remove any dust or dirt on leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended periods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or that contain wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
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 under the floor of the vehicle, and may also
cause the body to rust.
■Cleaning the inside of the windshield/rear window
●Be careful not to scratch or damage the heater wires or antenna.
●Do not use glass cleaner to clean the windshield/rear window, as this may cause
damage to the rear window defogger heater wires or wire antenna in the wind-
shield. Use a cloth dampened with lukewarm water to gently wipe the window
clean. Wipe the window in strokes running parallel to the heater wires or antenna.
