Rinse the sponge or glove thoroughly and often. 
Clean the wheels and under the door sills last. Use a different sponge 
or wash mitt. 
  WARNING 
After the vehicle has been washed, the wet brakes or, in winter, 
brake discs or pads coated with ice, react slower and need 
longer stopping distances. 
  Always dry the brakes and clean off any ice coatings with a 
few careful applications of the brake. Make sure not to endan-
ger other motorists or cyclists or disobey legal requirements.  
  CAUTION 
Sharp edges under the vehicle can cut exposed skin. 
  Always protect your hands and arms from cuts on sharp 
metal edges when cleaning the underbody, the inside of the 
wheel housings, etc.  
  NOTICE 
  The water temperature must not be more than +140 °F 
(+60 °C). 
  To help prevent damage to the paint, do not wash the vehicle 
in direct sunlight. 
  Do not use insect sponges, abrasive kitchen sponges or simi-
lar things to clean the vehicle. These can damage the paint fin-
ish. 
  Never clean headlights with a dry cloth or sponge. Always use 
a wet cloth or sponge. For best results use soapy water. 
  When washing or rinsing the vehicle in cold weather, do not 
let water get into the lock cylinders or point the hose at gaps 
around the doors, hood, or luggage compartment lid. The water 
could freeze on the locks and seals and make it difficult to open 
the vehicle!
