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

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.
