heater on to avoid the possibility of burns:

• Persons with sensitive skin
• Persons who are fatigued

objects (needles, nails, etc.) into the seat.

Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl or 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

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.
