WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis componentsr eplaced
immediately.
! Observe the minimum distance to be
maintained between the nozzle of the
power washer and objec ttobe cleaned, as
outlined below:
R approximately 2.2 ft(70 cm) when using
round-jet nozzles
R approximately 1ft(30 cm) whe nusing
25°flat-spray jets and dirt blasters
Keep the water jet moving while cleaning.
To avoid causing damage, do not point the
water jet directly at:
R door joints
R brake hoses
R electrical components
R electrical connections
R seals
R drive train, especially not at the
intermediate bearing of the propeller
shaft
R rear view camera (camera lens and
microphone opening on the bottom)
Keep a minimum distance of
1.6 ft(50 cm).
Cleaning the engine !
Water must not enter intake or ventilation
openings. When cleaning with high
pressure water or steam cleaners, the spray must not be aimed directly at
electrical components or the terminals of
electrical lines.
Preserve the engine after the engine has
been cleaned. Protect the belt drive system
from exposure to the preservative agent.
Also observe the information in the section
"Powerw asher" (Y page 257).
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces .You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by
inadequate care cannot always be completely
repaired. In such cases, visit a qualified
specialist workshop.
X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
