Wipe the wooden trim and trim elements
with a damp, lint-free cloth, e.g. a microfi-
bre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use microfibre cloths to clean gen-
uine leather, artificial leather or Alcantara®
covers. If used often, these can damage the cover.
i Note that regular care is essential to
make sure that the appearance and com-
fort of the covers are retained over time.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R Differences in the texture
R Signs of stretching and marking
R Slight nuances of colour
These are characteristics of leather and not
material defects.
! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a quali- fied specialist workshop. Seat covers of other materials
! Observe the following when cleaning:
R Clean artificial leather covers with a cloth
moistened with a solution containing 1% detergent (e.g. washing-up liquid).
R Clean cloth covers with a microfibre
cloth moistened with a solution contain-
ing 1% detergent (e.g. washing-up liquid).
Rub carefully, and always wipe entire
seat sections to avoid leaving visible
lines. Leave the seat to dry afterwards.
Cleaning results depend on the type of
dirt and how long it has been there.
R Clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
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 solu-
tion.
Cleaning the roof lining and carpets X
Roof lining: if it is very dirty, use a soft
brush or a cleaning agent recommended
and approved by Mercedes-Benz.
X Carpets: use the carpet and textile clean-
ing agents recommended and approved by Mercedes-Benz. 296
CareMaintenance and care

R
Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performance after this distance.
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.
Observe the notes on the emergency spare
wheel (Y page 332). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system and only on wheels specifi-
cally tested by Mercedes-Benz.
Notes on driving with MOExtended tyres with
a flat tyre (Y page 300).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist 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 324). 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.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tyres
G
WARNING
M+ Styres 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 pro-
vide the best possible grip in wintry road con- ditions. Only these tyres will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. These tyres have
been developed specifically for driving in
snow.
Use M+S tyres of the same make and tread on
all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres that have a lower maxi-
mum permissible speed than that of the vehi-
cle, affix an appropriate warning sign 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 speed of the vehicle
using permanent SPEEDTRONIC so that it 320

The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given for higher loads. These are permissible andwill not adversely affect the running of the
vehicle. Tyre pressure loss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a
loss of pressure, a corresponding warning
message will appear in the multifunction dis- play.
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 321).
The tyre pressure loss warning system 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 detected by the tyre pressure 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 (cor-
nering 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
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system
if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap.
The tyre pressure loss warning system can only give reliable warnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrect values
will be monitored.
