High-pressure cleaners
G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to failures or leaks.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
X Remove the following types of dirt immedi-
ately, whilst avoiding rubbing too hard.
Soak:
R insect remains with insect remover
R bird droppings with water and rinse off the treated surface after-
wards.
Remove:
R
tree resin, oils, fuels and greases by rub-
bing gently with a cloth soaked in petro-
leum ether or lighter fluid.
R tar stain with tar remover
R wax with silicone remover
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. Otherwise, you could
damage the paintwork.
Cleaning the wheels !
Do not use acidic wheel cleaners to
remove brake dust. This could damage
wheel bolts and brake components.
Cleaning the windows X
Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
product approved and recommended by
Mercedes-Benz.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Under certain circumstances,
deposits such as leaves, petals and pollen
may prevent water from draining away
leading to corrosion damage.
Cleaning the wiper blades G
Risk of injury
Before cleaning the windscreen or wiper
blades, turn the key to position 0in the igni-
tion lock or press the Start/Stop button* until
all indicator lamps have gone out in the instru-
