Information on using a high-p
ressure cleaner 000A
WARNING Risk of an accident when
using high-pressure cleane rswith circu‐
lar jet nozzles
The wate r jet of a circular jet nozzle (dirt
grinder) can cause extern ally invisible dam‐
age tothe tyres or chassis parts.
Components damaged in this wa y may unex‐
pec tedly fail. 0007
Do not use high-pressure cleaners with
circular jet nozzles toclean theve hicle. 0007
Have damaged tyres or chassis parts
re placed immediatel y. To
avo id damage to yourvehicle, obser vethefo l‐
lowing when using a high-pressure cleaner:
R keep theke y at least 3 m away from theve hi‐
cle. Otherwise the boot lid could open unin‐
te ntional ly. R
maintain a dis tance of at least 30 cm tothe
ve hicle.
R vehicles with deco rative foil: parts of your
ve hicle are co vered with a decorative foil.
Maintain a dis tance of at least 70 cm
between thefo il-c ove red parts of theve hicle
and the nozzle of the high-pressure cleaner.
Mo vethe high-pressure cleaner nozzle
around whilst cleaning. The waterte mp era‐
ture of the high-pressure cleaner must not
exc eed 60 °C.
R obser vethe information on the cor rect dis‐
ta nce in the equipment manufacturer's oper‐
ating instructions.
R do not point the nozzle of the high-pressure
cleaner directly at sensitive parts such as
tyres, the soft top, the wind deflector net,
slits, electrical component parts, batteries,
light sources and ventilation sl ots. Wa
shing theve hicle byhand Obser
vethe legal requ irements, e.g. in a number
of countries, washing byhand is only permitted
in specially designated wash ba ys. 0007
Use a mild cleaning agent, e.g. car shampoo. 0007
Washtheve hicle with luk ewarmwate r using
a soft car sponge. When doing so, do not
ex pose theve hicle todirect sunlight. 0007
Carefully hose theve hicle off with water and
dry using a chamois. Take care not topoint
th ewate r jet directly towa rdsth e air inlet
grille. Maintenance and care

WARNING Risk of accident when driving
in eme rgency mode
When driving in emer gency mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating stronglyand
when braking. 0007
Do not exceed the permissible maxi‐
mum speed. 0007
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road). This applies, in pa
rticular, toa loaded
ve hicle. 0007
Stop driving in the emer gency mode if
yo u notice:
R banging noise
R vehicle vibration
R smoke which smells like rubber
R continuous ESP ®

After driving in emergency mode ha ve
th erims checkedby aqu alified special‐
ist workshop with rega rd totheir fur ther
use. 0007
The defective tire must be replaced in
eve rycase. Wi
th MOExtended tyres (run-flat tyres), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tyres. How‐
eve r,th e tyre af fected must not show any clearly
visible damage. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears onthe side
wa ll of the tyre.
Ve hicles with tyre pressure loss warning sys‐

conjunction wi than activated tyre pressure loss
wa rning sy stem.
Ve hicles with tyre pressure monitoring sys‐
te m: MOExtended tyres may only be used in
conjunction wi than activated tyre pressure mon‐
itoring sy stem.
If a pressure loss warning message appears in
th e multifunction displa y,proceed as follo ws:
R Check the tyre for dama ge.

Let the tyre inflation compressor runfo r a
maximum of ten minu tes.
The tyre should then ha veattained a tyre
pressure of at least 200 kPa (2.0 bar/

If tyre sealant leaks out, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clear water.

WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs driving characteristics and is not
suitable for higher speeds. 0007

Note
s on noise or unusual handling charac‐
te rist ics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling
ch aracteristics. If youfind no signs of damage,
ha ve the tyres and wheels checked at a qualified
specialist workshop. Note

WARNING Risk of accident from dam‐
aged tyres
Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. 0007
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (0013 page 432).
R Visually inspect tyres and wheels for dam‐
age.
R Check theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.
R Visual check of the tyre tread dep thand the
tyre contact su rface across the entire width.
The minimum tread dep thfor summer tyres
is 3 mm and for winter tyres 4 mm. Note
