When you have fitted M+S tyres:
X
Check the tyre pressures (Y page 365).
X Restart the tyre pressure loss warning sys-
tem (Y page 367).
X Restart the tyre pressure monitor
(Y page 369).
After fitting a spare wheel or an emergency
spare wheel, do not drive faster than
80 km/h. G
WARNING
The wheel/tyre dimensions and the tyre type
of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To preven thazardous situations:
R Adap tyour driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimesions are dif-
ferent to those of the wheel being replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimesions are different
to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct. 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, or that are of a corre-
sponding standard of quality. If you intend to fit snow chains, please bear
the following points in mind:
R
snow chains cannot be fitted to all wheel-
tyre combinations. Permissible wheel-tyre
combinations (Y page 371).
R snow chains must not be fitted to the emer-
gency spare wheel, e.g. a “Minispare” or
collapsible emergency spare wheel.
R only fit snow chains in pairs and to the rear
wheels, even on vehicles with 4MATIC.
Observe the manufacturer' sinstallation
instructions.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure tha tyou remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
On vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
fitted (Y page 197).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate
ESP ®
(Y page 72) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner,
achieving an increased driving force (cut-
ting action). Tyre pressure

WARNING
Tyres with too low or too high tyre pressure
contain the following hazards:
R they can burst, in particular if the vehicle is
heavily laden or when driven at high
speeds.
R the tyres can wear excessively and/or
unevenly, which can severely impair tyre
traction.
R the driving, steering and braking character-
istics may be severely impaired. Tyre pressure
365Wheels and tyres
Z
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 tha tis too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative 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, at least
every 14 days.
Speeds up to 210 km/h (does not apply
to AMG vehicles): despite the values stated
on the tyre pressure information label (fuel
filler flap), for speeds up to 210 km/hand
with R16 or R17 tyres, the values stated can
be reduced as follows without a reduction in
safety:
R Saloon: Ò30 kPa (Ò0.3 bar, Ò4psi)
R Estate: Ò20 kPa (Ò0.2 bar, Ò3psi)
This does not apply to vehicles towing a
trailer.
This improves the ride comfort of your vehi-
cle; however, the fuel consumption may
increase slightly. 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 appearint
he 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 365).
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

R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap Tyre pressure

to ensure tha
tthe tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
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 incorrectv alues
will be monitored.

Important safety notes It is the driver's responsibility to set the tyre
inflation to the recommended cold tyre pres-
sure suitable to the operating situation
(Y
page 365). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor.
If there is a substantial loss of pressure, the
warning threshold for the warning message is
aligned to the reference values entered.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure.
(Y page 369) The current pressures are
saved as new reference values. As a result, a
warning message will appearift he tyre pres-
sure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 365).
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.
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the correct sensors are fitted to all wheels.
Information on tyre pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tyre pressure of each
tyre is shown in the multifunction display.
i The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge 368
