Care of exterior
Washing
Frequen t washing pro tects the vehi cle.
Th e bes t protection against envi ronmental influences is frequent
washing and waxing . How often this is required depends on:
• Ho w much the vehic le is used
• Where the vehic le is parked (garage, in the open under trees,
etc.)
• T he seasonal and weather conditions
• Environmenta l influences
T he longer bird droppings, insects, tree resin, road and industrial
gri me, tar, soot, road salt and ot her materials rema in on the ve hicle
body, the more lasting their destruc tive effects will be . High temper ­
atu res caused by exp osu re to in tense s un ligh t inte nsify the c orro -
sive effect, particularly when humidity is high as well.
