156 Vehicle care and cleaning
_& WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp metal components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications .
@ Note
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors. Power folding exterior mir­ rors* must only be folded in and out us­
ing the power folding function.
- To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To reduce the risk of damage, do not
wash the power top with a pressure
washer. -
To reduce the risk of damage, do not
wash decorative decals* with a pressure
washer.
- To reduc e the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:

surface, do not use polishing agents or
hard wax.
