trailer stabi-
lisation (Y page 55).
In Germany, th emaximum permissible speed
for vehicle/trailer combinations depends on
th et ype of trailer and is either 80 km/h or
10 0k m/ h. In som ecountries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations .Before beginnin gthe
journey, check th etrailer' sdocuments to see
what th emaximum permitted spee dis.
For certain Mercedes-Ben zvehicles, th emax-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical
data" sectio ntofindo ut whether this applies
to your vehicle .Ifyou utilise any of th eadded
maximum rear axle load when towing atrailer,
th ev ehicle/trailer combinatio nmay not
excee damaximum spee dof100km/h for
reason sconcernin gthe operatin gpermit. This also applies in countries in whic
hthe
permissible maximum spee dfor vehicle/
trailer combinations is abov e100 km/h. G

Always observ ethe maximum spee dpermit-
te dinG ermany for vehicle/traile rcombina-
tions ,eveninc ountries wher ehigher speeds
are permitted. This lower sthe riskofana cci-
dent.
When towing atrailer, your vehicle's handling
characteristic swill be different in comparison
to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleratio nand gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected mor ebystron gc rosswinds
R demands mor esensitive steering
R consumes mor efuel
On lon gand steep downhill gradients ,you
must selec talower gear in good time, or on
vehicle switha utomatic transmission*, select
shif trange 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONI CorDIS-
TRONIC PLUS*.
This will use th ebraking effect of th eengine,
so less braking will be required to maintain
th es peed. This relieves th eload on th ebrake
system and prevents th ebrakes from over-
heating and wearin gtoo quickly. If you need
additional braking ,depress th ebrak epedal
repeatedly rather than continuously. G
Ris
kofa ccident
Never depress th ebrak epedal continuously
while th evehicle is in motion ,e.g.n ever cause
th eb rakes to rub by applyin gconstant slight
pedal pressure .This causes th ebrak esystem
to overheat, increases th ebraking distance
and can lead to th ebrakes failin gcompletely. Trailer towing*

Risk of accident
Braking efficiency is reduce dafterw ashing
the vehicle .Thisc ould cause an accident. For
this reason, following acar wash, drive with
particula rcare unti lthe brakes are dry.
You can wash the vehicle in an automatic car
wash from the beginning.
! We recommend automatic car washes
with an adjustable 38
high-pressure pre-
cleaning program. In car washe sthat use
hig hw ater pressures, there is adanger that
as mall quantity of water may leak into the
vehicle.
! Cabriolet: do not treatthe vehicle with
hot wa xunder any circumstances.
! Cabriolet: pull the key ou tofthe ignition
lock whe nwashing the vehicle .This
ensures that the wind deflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitabl efor the size of the vehicle .Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise ariskofd am-
ag etot he exterior mirrors.
! Whe nwashing your vehicle in atow-
through car wash, make sure that the auto-
mati ctransmission* is in position N.The
vehicle could otherwise be damaged.
! Make sure that the sid ewindow sare com-
pletel yclosed, that the ventilation/heater
blower is fully turne doff and that the wind-
scree nwiper switch is set to 0.Otherwise,
the rain/light senso rmay be activated, trig-
gering unintende dwiper movements. This
could cause damag etothe vehicle.
After using an automatic car wash, wipe off
wa xa nd drying agents from the windscreen and the wiper blades. Thi
swillp revent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not us ehigh-pressure cleaners with circu-
lar-jet nozzle s(dirt grinders )toclean your
vehicle ,inparticula rthe tyres. You could oth-
erwise damag ethe tyre sand cause an acci-
dent.
! Observe the instructions issue dbythe
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleane rand the
vehicle (a tleast 30 cm).
Move the high-pressure cleane rnozzle
around whe ncleaning your vehicle.
Do not ai mdirectl yata ny of the following:
R tyres
R doo rjoint
R soft top (Cabriolet)
R wind deflector net (Cabriolet)
R electrical components
R battery
R connectors
R lights

Do not clean the camera lens and the area
around the reversing camera with ahigh-
pressure cleaner.
Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. Reg-
ularc are of the exhaust tail pipes will ensure
that their original shine is restored.
! Do not clean the exhaust tail pipes with
alkaline-based cleaning agents such as
wheel cleaner.
X Cleant he exhaust tail pipes with achrome
care product approved by Mercedes-Benz.
Trailer tow hitch* The ball coupling must be cleaned if it
becomes dirty or corroded.
X Remove any rust using awire brush.
X Remove dirt with aclean, lint-free cloth or
ab rush.
! Do not clean the ball coupling with ahigh-
pressure cleaner. Do not use solvents. X
After cleaning, lightly oil or grease ball cou-
pling 0046.
X Check that the vehicle's trailer tow hitch is
working properly.
! Observe the note on care provided by the
trailer manufacturer. i
Maintenance of the ball coupling and
trailer tow hitch can also be performed by
any Mercedes-Benz Service Centre. H
Environmental note
Dispose of oily and greasy cloths in an envi-
ronmentally-responsible manner. Interior care
Cleaning the steering wheelb oss and
dashboard G
Risk of injury
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult, plastic
parts may break awayw hen an airbagis
deployed, which may result in severe injuries.
X Wipe the dashboard and steering wheel
boss with adamp, lint-free cloth (e.g. a
microfibre cloth) and cleaning agent.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
