ESP MERCEDES-BENZ E-CLASS CABRIOLET 2011 Owners Manual

Only winter tyres bearing the
isnowflake
symbol in addition to the M+S marking pro-
vide the best possibleg rip in wintry road con-
ditions. Only these tyres will allowd riving
safety systems such as ABS and ESP ®
to
function optimally in winter, as these tyres
have been designed specificallyf or driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
WARNING
M+S tyres with atread depth of less than
4mmm ust be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficient grip .This could cause you to
lose control of your vehicle and cause an acci-
dent.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have alower max-
imum 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 aq ualified specialist workshop, e.g. at a
Mercedes-Ben zService Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 183).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 321).
X Restart the tyre pressure loss warning sys-
tem (Y page 322). G
WARNING
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable corneringc har-
acteristics caused by the different tyres. You
should therefore adapt your driving style and
drive carefully. Have the spare wheel replaced at the nearest
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use
aMercedes-Benz
Service Centr efor this purpose. 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 chains that
have been specially approved for your vehicle
by Mercedes-Benz ,orthat are of acorre-
spondin gstandard of quality.
If you inten dtofit snow chains, please bear
the following point sinmind:
R it is not permissible to attac hsnow chains
to all wheel-tyre combinations; see the
information under "Wheel/tyre combina-
tions" in the "Wheels and tyres" section.
R snow chains must not be fitted to emer-
genc yspare wheels, e.g. a"Minispare"
emergency spare wheel.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first .The hubcaps may
otherwise be damaged.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
(Y page 64) when pulling away with snow
chains fitted. This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). 320
Winter operationWheels and tyres

is kept open continuously, which may lead to
air loss. G
WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only avalve cap approved
by Mercedes-Ben zisfitted on the tyre
valve.
Tyre pressures that are too low have anega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i 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 and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days. Tyrep
ressur eloss 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
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
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 asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
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 conditionsa re 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 towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof). 322

WARNING
The brak efluid constantly absorb smoisture
fro mt he air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
