NOTICE
Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic or
cause damage.
3. Rinse thoroughly — dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard — you might scratch the
paint.
NOTICE
D To prevent damage to the antenna, make sure it is
removed before driving your vehicle through an
automatic car wash.
D When your vehicle goes through an automatic car
wash, make sure the power back door system is off.
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.
Automatic car wash
