Environmental note
Daimler's declared polic yisone of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
plane ttobeu sed sparingl yand in amanner
which takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors.
You shoul dbear the following in mind:
Operating conditions
R avoid short trips as these increase fuel con-
sumption.
R mak esure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protec tion. You should
therefor eadhere to the service inter vals.
R always have maintenance work carried out
at aq ualified specialist workshop ,e.g. a
Mercedes-Benz Service Centre.
Personal driving style
R do not depress the accelerator pedal when
starti ngthe engine.
R do not warm up the engine with the vehicle
stationary. R
drive carefully and maintain asafe distance
from the vehicle in front.
R avoid frequent, sudden acceleration.
R change gear in good time and use each gear
only up to 2
/ 3 of its maximum engine
speed.
R switch off the engine in stationary traffic. Returning used vehicles
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles of up to 3.5 tgros svehicle weight, in
accordance with national regulations. For
sever alyears, Mercedes-Benz has been
meeting all the lega lrequirements for a
design which allows for recycling and reuse.
There is anetwor kofreturnpoint sand dis-
ass embly plants which can recycle your vehi-
cle in an environmentally-responsibl eman-
ner. The options for recyclin gvehicles and
part sare constantly being developed and
improved. This means that your Mercedes-
Benz will als ocontinue to meet even the
inc reased recyclin gquotas in the future in
good time. You can obtain further information
from your national Mercedes -Ben zh omepage
or your national hotlin enumber. Vehicle equipment

Gen
eral information i
When towing atrail er,s et the tyr epres-
sure on th erear axle of the towing vehicle
for am aximum load; se ethe tyr epressure
table in th efuel filler flap.
You will find installatio ndimensions and loads
in the "Technical data” section
(Y page 322).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However ,the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight .Do
not use anoseweight of less than 50 kg,
otherwise the trailer ma ycome loose.
Bear in min dthat the payload and the rear
axl eload ar ereduced by the actual nose-
weight.
Please not ethat when towing atrailer, PARK-
TRONIC (Y page 174) and parkin gguidance
(Y page 177 )are onl yavail ablew ith limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer wit haheight-adjustable draw-
bar.
Driving tips i
Observ ethe notes on ESP ®
trailer stabi-
lisation (Y page 58).
In Germany, the maximum permissible speed
for vehicle/ trailer combinations depends on
the type of trailer and is either 80 km/ hor
100 km/h. In some countries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Befor ebeginnin gthe
journey ,check the trailer's documen tsto see
what the maximum permitted speed is.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical data
"section to fin dout whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing atrailer,
th ev ehicle/ trailer combination may not
exceed amaximum spee dof100 km/h for
reasons concerning the operating permit.
This als oapplies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 10 0km/h.
When towing atrailer, your vehicle's handling
characteristics wil lbedifferent in comparison
to when drivin gwithout atrailer.
Th ev ehicle/ trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demand smore sensitive steering
R consume smore fuel
On long and steep downhil lgradients ,you
must shift to alower gear in good time, or on
vehicles with automatic transmission ,select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly .Ifyou need
additional braking, depress the brake pedal
repeatedly rather than con tinuously.
Driving tips R
Maintain agreater distance from th evehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea 188

possible ,whilst avoidin grubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils ,fuels and greases by rubbing gently
with acloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remov etar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Care and treatment of mat tpaintwork If you
rvehicle has aclear matt finish, observe
the following instruc tions in order to avoid
damage to the paintwor kdue to incorrect
care.
! Under no circumstances should you pol-
ish the vehicle. Polishing will make the
paintwork shine.
! Do not use paintwork cleaner, grinding or
polishing products or glos spreservers such
as wax .These product sare onl ysuitable for
high-glos ssurfaces. Using them on vehi-
cles with matt paintwork can cause severe damage to the surface (shiny, mottled
patches).
Always have paintwork repairs performed
at
aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre.
! Do not use wash programs with ahot wax
treatmen tunder any circumstances.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Be nz care products.
Cleanin gthe cabriolet soft top X
Light soiling: you can clean the sof ttop
whil eitisd ry or rinse it with clear water.
X Norma ltoheavy soiling: clean theroof
wit hab rush and clear water. Clean stains
and othe rdirt wit habrush and aMercedes-
Ben zrecom mended and approved cleani ng
agent. Always brush from fron ttoback in
the direction of the fabric.
! Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as
they are corrosive and, therefore, can make
the soft- topf abric leak. Do not use high-
pressure cleanin gequipmen ttoclean the
vehicle. Do not use sharp-edged equipment
to remov eice and snow.
Frequent cleaning reduce sthe resistanc eto
dirt of the soft top.
To restore this resistanc etodirt, clean the
soft top using soft top cleanin gagents that
have been recommended and approved by
Mercedes-Benz.
In co rrect cleaning and care, as well as ageing,

R When parking your vehicle, make sure that
the tyres do not ge tdeformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or simila releva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Maintenance and care of wheels and
tyres
Checking wheels and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
crack sorseverecorrosion on wheels), at
least ever y14d ays, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss of tyr epressure.
R Regu larly check th etyre tread depth and
the conditio nofthe tread across the whole
widt hofthe tyr e(Ypage 299). If neces-
sary, tur nthe front wheels to full lock in
orde rtoi nspect the inner sid eofthe tyre
surface.
R All wheels must hav eavalve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitorin gsystems) othe rthan
the standar dvalve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly chec kthe pressur eofall the tyres
including the emergenc yspare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressur easnecessary
(Y page 299). Ty
re tr ead G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they will no
longer provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the steerin gwheel so that you can see
the tyr etrea dm ore easily.
You coul dotherwise los econtrol of the vehi-
cle and cause an acciden tdue to the reduced
grip of the tyres on the road. Storing tyres
Store tyres that are not being used in acool,
dry and preferably dar kplace. Protect the
tyres against oil, grease, petrol and diesel. Cleaning tyres
! Do not use ahigh pressure jet with circu-
lar jet nozzles (concentrated-power jets) to
clean the tyres. The high pressure of the
water jet could damage the tyres. Always
replace damaged tyres. Tyr
epressures Recommended ty
repressures
You will find atable of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the

The applicable value for the maximum load on
the rea raxle during trailer towing is state don
the tyre pressure information label on the
insid eofy our vehicle' sfuel filler flap.
The load condition "partially laden" or "fully
laden" is defined in the table by the differing
number of passengers and amount of lug-
gage. The actual number of seats may vary
from this –more information can be found on
the vehicle' sregistra tion document.
If no other data is stated, the tyr epressures

pressure specification that follows is only
valid for that tyre size. Instead of the complete tyre size, it may be
that only the rim diameter is stated ,e.g.
R16. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall. G
Risk of accident
Tyre pressure that is either too hig hortoo low
has anegativ eeffect on the vehicle's driving
safety ,which coul dlead you to cause an acci-
dent. Therefore, you should regularly check
the pressur eofall the tyres, particularly prior
to long trips, and correc tthe pressure as nec-
essary.
To test tyr epressure, us easuitable pressure
gauge. The outer appearance of atyre does
not permit any reliabl econclusion about the
tyr ep ressure. G
Ris
kofa ccident
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously ,which ma ylead to
air loss. G
Risk of accident
Should the tyr epressure dro prepeatedly:
R check the tyr efor foreign bodies.
R chec kwhether the wheel is losing air or the
valve is leaking.
R make sur ethat only avalve cap approved
by Mercedes-Benz has been fitte donthe

Tyr
ep ressures that are too lo whave anega-
tiv ee ffect on vehicl esafety, which could lead
to your causing an accident.
If possible, you should only correc ttyre pres-
sures when the tyres are cold. Depending on
the ambien ttemperature, the speed you are
driving at and the load on the tyres, the tyre
temperatur eand thus the tyre pressure may
chang ebyapproximately 10 kPa (0. 1bar,
1.5 psi) per 10 †. Take this int oaccount
whe ncheckin gthe pressur eofwarm tyres
and only correct it if it is too low for the cur-
rent operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the servic elife of the tyres
R cause increased tyre damage
R have anegativ eeffect on handling charac-
teristi csand thus the driving safet y(e.g. by
causing aquapla ning)
i The tyr epressure values given for low
load sare minimum values which offe ryou

However ,you can also use the values given
for higher loads. These ar epermissible and
will not adversely affect the running of the
vehicle. H
Environmenta
lnote
Check the tyre pressure regularly, at least
every 14 days. Tyr
epressure loss warning
Important safety notes Whil
ethe vehicle is in motion, the tyr epres-
sure loss warning system monitors th eset
tyr ep ressure using th erotational speed of
the wheels. This enables the system to detect
significant pressure loss in atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorrespondin gwarning
message will appea rinthe multifunction dis-
play. G
Risk of accident
The tyr epressure loss warning system does
not warn you of an incorrectly se ttyre pres-
sure. The table on the insid eofthe fuel filler
fla pw ill help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warnin gsystem does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detecte dbythe tyr epressure loss
warning system.
Th et yre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign objec t.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towin gavery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).
