characteristics cause
dbythe differ enttyres.
You shoul dtherefor eadapt your drivin gstyle
and drive carefully.
Have the spare whee lreplaced at the nearest
qualified specialist workshop which has the
necessar yspecialist knowledge and tools to
carry out the work required. Mercedes- Benz
recommends that you use aMercedes-Benz
Ser vice Centre for thi spurpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at aqualified
specialist workshop.
Snow chains For safety reasons
,Mercedes-Benz recom-
mends that you only use snow chain swhich
hav ebeen speciall yapproved for your vehicle
by Mercedes-Benz ,ora re of acorresponding
standar dofquality.
If you intend to fit snow chains, pleas ebear
the following point sinmind:
R you may not attac hsnow chains to all
wheel-tyre combinations ;see the "Tyres
and wheels" section in the "Techni caldata"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels ,e.g. a"Minispare"
emergency spar ewheel.
R fit snow chains only in pair sand only to the
rear wheels .Observ ethe manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km /h.
i You may wish to deactivat eESP®
when
pulling away with snow chains fitted
(Y page 57). This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an inc reased driving forc e(cutting
actio n).
Slipper yroad surfaces G
Risk of accident
Do not shift down for additional engine brak-
ing on aslippery road surface. This could cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion ,steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when movin gatlow speed:
X Vehicles with manua ltransmission: engage
neutral.
X Vehicles wit hautomatic transmission: shift
the transmission to position N.
X Try to bring the vehicle under control using
corrective steering.
i For more information on driving with
snow chains, see (Y page 157). Drivin

General notes An extensiv
eMercedes–Benz Ser vice net-
work is als oavailable in othe rcountries. The
Ser vice Hotline's current telephone numbers
for use whe nyou ar eabroad are to be found
in the "Service24h" section of the Ser vice
Boo klet.
Only low-oc tane fuel is available in certain
countries.
You can find further information about fuel
grade son(Ypage 14 8).
Sym metrical dipped-beam headlamps If your journey takes you to countries where
vehicle
sare driven on th eopposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. This prevents
oncomin gtraffic from being dazzled.
Have th eheadlamps conver tedasc lose as
possible to the border before drivin ginthese
countries. When usin gsymmetrical lights, the
edg eoft he carriageway is not lit as widely
and as fa rahead as nor mal. Drivin

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

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,
can cause th esoft top seam stoleak. Have
the soft-top seams sealed at aqualified spe-
