Example: washer fluid reservoir
XTo open: pull cap:upwards by the tab.
X Add the premixed washer fluid.
X To close: press cap :onto the filler neck
until it engages.
On vehicles with the headlamp cleaning sys-
tem, the recommended minimum washer
fluid level is 0.92 US ga l(3.5 liters). On vehi-
cles without the headlamp cleaning system,
the recommended minimum washer fluid
level is 0.26 US gal (1liter). If the washer fluid
level drops below the recommended mini-
mum fluid level of 0.26 US gal (1 liter), a mes-
sage appears in the multifunction display
prompting you to add washer fluid( Y page 148).
Further information on windshield washer
fluid/antifreeze ( Ypage 265).
Brake fluid level
!If you notice that the brake fluid level in
the brake fluid reservoir has fallen to the
MIN mark or less, check the brake system
immediately for leaks. Also check the thick-
ness of the brake linings. Visit a qualified
specialist workshop immediately.
Do not add brake fluid. This does not cor-
rect the error.
Only check the brake fluid level when the
vehicle is on a level surface.
If the brake fluid level is between MIN mark :and MAX mark ;on the brake fluid
reservoir, it is correct.

Care
General notes
GWARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the particu-
lar container. Always open your vehicle's
doors or windows when cleaning the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children.
!For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner. Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
Exterior care
Information in the Digital Operator's Manual
In the Digital Operator's Manual you will find
information on the following topics: R Washing by hand
R Power washers
R Cleaning the wheels
R Cleaning the paintwork
R Matte finish care
R Cleaning the windows
R Cleaning wiper blades
R Cleaning the headlamps
R Cleaning the sensors
R Cleaning the rear view camera

Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can damage the paintwork or plastic parts.
!Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. The exterior mirrors could other-
wise be damaged.
