Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
The "Residual heat" function can only be activa- ted or deactivated with the ignition switched off
(Y page 132).
i Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling process and the desired interior temperaturewill be reached more quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odours. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat function
may be activated automatically an hour after
the key has been removed. The vehicle is then ventilated for 30 minutes to dry the automaticclimate control. Overview of climate control systems

These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the vehicle body
R you should drive no faster than walking pace Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to bring the vehicle under control by using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always
adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

!
When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This cor-
responds with the specifications for cabriolet
programmes. In car washes that use high
water pressures, there is a risk that a small
amount of water may leak into the vehicle.
! Make sure that the vehicle is not subse-
quently treated with hot wax.
! Make sure that:
R the side windows and sliding sunroof or
soft top are closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at position
0.
The vehicle could otherwise be damaged.
! In car washes with a towing mechanism,
make sure that the automatic transmission is
in transmission position N; otherwise, the
vehicle could be damaged.
R Vehicles with DIRECT SELECT lever and
key:
do not remove the key from the ignition
lock. Do not open the driver's door or front- passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position Pauto-
matically and locks the wheels. You can
prevent this by shifting the automatic trans-
mission to Nbeforehand.
R Vehicles with DIRECT SELECT lever and
KEYLESS-GO:
do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position Pauto-
matically and locks the wheels.
Observe the following to make sure that the
automatic transmission on vehicles with DIRECT
SELECT stays in position N:X
Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2in the ignition lock
(Y page 139).

in an automatic car wash.
After using an automatic car wash, wipe off wax
from the windscreen and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windscreen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a gen-
tle jet of water.
X Do not point the water jet directly towards the
air inlet.
X Use plenty of water and rinse out the sponge
frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the paint-
work.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible. 296
CareMaintenance and care

Cleaning vehicle parts
Cleaning the soft top !
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-top fabric leak. Do not use high-pressure cleaning equipment to clean the vehicle. Do
not use sharp-edged equipment to remove ice
and snow.
X Light soiling: you can clean the soft top while
it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the roof with
a brush and clear water. Clean stains and
other dirt with a brush and a Mercedes-Benz
recommended and approved cleaning agent.
Always brush from front to back in the direc-
tion of the fabric.
Frequent cleaning reduces the soft top's resist- ance to dirt.
To restore this resistance to dirt, clean the soft
top using soft-top cleaning agents that have
been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as ageing,
can cause the soft-top seams to leak. Have the
soft-top seams sealed at a qualified specialist
workshop, e.g. at a Mercedes-Benz Service
Centre.
i Cover the soft top appropriately if you plan
to leave the vehicle outside for a long period
of time.
Cleaning AIRCAP Cleaning the wind deflector
! Do not use high-pressure cleaning equip-
ment to clean the net.
Clean the wind deflector on the windscreen with
the soft top closed.
X Apply the parking brake firmly.
X Vehicles with key: turn the key to position
2 (Y page 139) in the ignition lock. X
Vehicles with KEYLESS-GO: press the
Start/Stop button twice (Y page 139).
X Open the cover on the lower centre console.
The AIRCAP button is under the cover. X
Press AIRCAP button :.
The wind deflector between the windscreen
and the soft top is extended. X
Clean net ;of the wind deflector with a soft
brush or a moist cloth. For heavier soiling,
clean it with the care and cleaning agents
recommended and approved by Mercedes-
Benz and rinse it with clean water.

CareMaintenance and care

Cleaning the seat belts
G
WARNING
Seat belts may be severely weakened if
bleached or coloured. This may lead to the
seat belts, for example, tearing or failing in an accident. There is an increased risk of injury,
possibly even fatal.
Never bleach or colour seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts at
temperatures above 80 † or in direct sun-
light.
X Use clean, lukewarm water and soap solution.

reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 333). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi- cle even if there is a total loss of pressure in one
or more tyres.
MOExtended tyres may only be used in conjunc- tion with an activated tyre pressure loss warning system or with an activated tyre pressure mon-
itor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (Y page 306).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 329). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the maximum
design speed of the vehicle, affix a correspond- ing warning label in the driver's field of vision.
This can be obtained at a qualified specialist
workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 168). Winter operation

warning system" section (Y page 326).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 324).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre is penetrated by a foreign object. In the event of
a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering
manoeuvres.
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 a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the vehi-
cle or on the roof).
