Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 60). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Only operate the vehicle for a maximum
of ten seconds on a brake dynamometer.
Switch off the ignition.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! A function or performance test should
only be carried out on atwin-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop .You could otherwise
damage the drive train or the brake system.
ESP ®
monitors driving stability and traction.
Traction is the transmission of power from the
tyres to the road surface.
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 256) and any display messages that
appear in the instrument cluster
(Y page 229). If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the ÷warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the accel-
erator pedal as far as is necessary.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
i If differential locks are switched on, ABS,
BAS and ESP ®
switch off automatically.
4ETS (Electronic Traction System) Traction control remains active if you deacti-
vate ESP
®
.
X If appropriate for the driving conditions,
engage the LOW RANGE off-road gear
(Y page 202).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
.
Traction control is no longer active above a
speed of about 60 km/h. 62

after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio
nofthe brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry.
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This
corresponds 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.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. The exterior mirrors could other-
wise be damaged.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (airflow control is turned to position
0/theÃandÁ buttons
are switched off).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle 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 wind-
screen.
High-pressure cleaning equipment G
WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain a distance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R soft top (Cabriolet)
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures. 296

Regular checking of wheels and tyres
R Regularly check the wheels and tyres of
your vehicle for damage at leas tevery 14
days, as well as after driving off-road or on
rough roads. Damage includes cuts, punc-
tures, cracks and bulges on tyres or severe
corrosio nordeformation on wheels, for
example. Damaged wheels can cause a
loss of tyre pressure.
R Regularly chec kthe tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 323). In order to
inspect the inner side of the tyre surface,
turn the steering wheel to full lock.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve other than the
standard valve cap or avalve cap approved
by Mercedes-Ben zfor your vehicle.
Do not fit anything onto the valve, such as
tyre pressure monitoring systems.
R You should regularly check the pressure of
all your tyres including the spare wheel,
particularly prior to long trips. Adjust the
tyre pressure as necessary (Y page 328).
The service life of tyres depends on various
factors, including the following:
R driving style
R tyre pressure
R tyre mileage Tyre tread
G
WARNING
Please keep in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless, as they no lon-
ger provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the fron
twheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Selecting, fitting and replacing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit approved tyres of the correct size
onto the wheels.
R Tyres are supplied with a protective layer
from the factory. Run in new tyres at mod-
erate speeds for the first 100 km. They only
reach their full performance after this dis-
tance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel. 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 vehi-
cle to M+S tyres. Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently. Winter operation

You may wish to deactivate
ESP ®
(Y page 62) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner,

Important safety notes G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and
chec kthe tyre pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R when the load changes
R before embarking on a longer journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and
malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is
a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Ben zfor
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
General notes You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Operation with a trailer:
the applicable
value for the rear tyres is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
The table inside the fuel filler flap may state
tyre pressures for different load conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information, please refer to the vehi-
cle's registration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure information
label apply for all tyres approved for this vehi-
cle. Tyre pressure
