High-pressure cleaning

G
WARNING
The water jet from a round-jet nozzle (dirt
grinder) can cause damage to tyres, suspen-
sion components or air bellows that is not
visible from the outside. Components that
have been damaged in this way can unex-
pectedly fail. There is a risk of an accident.
Do not use a high-pressure cleaner with a
round-jet nozzle to clean your vehicle. Have
damaged tyres, suspension components or
air bellows replaced immediately.
! Never use a high-pressure cleaner in the
vehicle interior. The pressurised water cre-
ated by the high-pressure cleaner and the
associated spray could cause considerable
damage to the vehicle.
®
! The BlueTec exhaust gas aftertreatment
system may only be cleaned when it is cool.
The sensors could otherwise be damaged.
When cleaning, make sure never to point
the water jet at the exhaust pipe. The
exhaust gas aftertreatment could other-
wise be damaged.
! When using a high-pressure cleaner, keep
a minimum distance between the high-
pressure nozzle and the vehicle parts. Parts
of the vehicle or engine can otherwise be
damaged.
Observe the following minimum distances:
Round spray jet approximately 70 cm
R
25°flat-spray jet approximately 30 cm
R
Dirt grinder approximately 30 cm
R
! Keep the water jet moving constantly
while cleaning. In this way, you will avoid
causing damage.
Do not point the water jet at:
door joints
R
air bellows
R
brake hoses
R
wheel balance weights
R
electrical components
