&
WARNING Risk of an accident when using
high-pr
essure cleaners with round-spray
nozzles
The water jet can cause externally invisible
damag
e.
Components damaged in this way may unex-
pectedly fail. 
Do not use a high-pressure cleaner with
r

ound-spray nozzles. 
Have damaged tyres or chassis parts
r

eplaced immediately. To avoid damage to your vehicle, observe the fol-
lo
wing when using a high-pressure cleaner:
= The key is at a minimum distance of 3 m away
from the vehicle. Otherwise, the tailgate could
open unintentionally.
= Maintain a distance of at least 30 cm to the
vehicle.
= Vehicles with decorative foils: Parts of your
vehicle are covered with a decorative foil.
Maintain a distance of at least 70 cm between
the foil-covered parts of the vehicle and the
nozzle of the high-pressure cleaner. Move the
high-pressure cleaner nozzle around whilst
cleaning. The water temperature of the high-
pressure cleaner must not exceed 60°C.
= Observe the information on the correct dis-
tance in the equipment manufacturer's oper-
ating instructions.
= Do not direct the nozzle of the high-pressure
cleaner directly at sensitive parts, e.g. tyres,
gaps, electrical components, batteries, illumi-
nants or louvres. 392
Maintenance and care

Washing the vehicle by hand
*
NOTE Engine damag e due to water ingress 
Take care not to point the water jet
dir

ectly towards the air inlet grille below

some countr
ies, washing by hand is permitted
only in specially designated wash bays). 
Use a mild cleaning agent (e.g. car shampoo). 
Wash the vehicle with lukewarm water using a
sos car spong

e. When doing so, do not
expose the vehicle to direct sunlight. 
Carefully hose the vehicle oM wit

or cleaning, use plenty of water and a mild
cleaning agent without additives or abrasive
substances (e.g. a car shampoo approved for
Mercedes-Benz).
= Remove dirt as soon as possible. Avoid rub-
bing too hard in order not to damage the dec-
orative Nlm irreparably.
= If there is dirt on the Nnish or if the decorative
Nlm is dull: use the paint cleaner recommen-
ded and approved for Mercedes-Benz.
= Insect remains: soak with insect remover and
rinse oM the treated areas aserwards.
= Bird droppings: soak with water and rinse oM
aserwards.

Nlms are impaired by:
- Sunlight
- Temperature (e.g. hot air blower) -
W eather conditions
- Stone chippings and dirt
- Chemical cleaning agents
- Oily products
= Do not use polish on matt decorative Nlm. Pol-

wrapped surface.
= Do not treat matt or structured decorative
Nlms with wax. Permanent stains may occur.
Scratches, corrosive deposits, areas aMected by
corrosion and damage caused by incorrect care
cannot always be completely repaired. In this
case, contact a qualiNed specialist workshop.
You can obtain more information on care and
cleaning agents from the manufacturer.
In the case of Nlm-wrapped surfaces, visual diMer-
ences may occur between the surfaces that were
not protected by a decorative Nlm aser a decora-
tive Nlm has been removed.
