leather surfaces immediately.
●Do not expose the vehicle to
direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.
●Do not place items made of
vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■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 such as the
audio system above or under the
