If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be
adapted according to the specifications given
in the fuel filler flap
(Y page 148).
Use the highest specified tyre pressure for
the spare wheel* . G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking .
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident .
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Therefore, you should only correct tyre pres-
sures when the tyres are cold. The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions.
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damag e
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel*. H
Environmental not
e
Check the tyre pressure regularly, and at
least every 14 days. Tyre pressure loss warning system*
G
Risk of accident
The tyre pressure loss warning system doe s
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel fille r
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 loss warning system 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 care-
fully. Do not make any sudden steering
movements when doing so.
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 spee d
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning Operation

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 grave l
R you adopt a very sporty driving style (cor -
nering at high speeds or driving with high
rates of acceleration)
R you are driving with a heavy load (in th e
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 tyre s
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler fla p
to ensure that the tyre pressure in all fou rtyres is set correctly for the operating con-
ditions concerned
.
X Also observe the notes in the section on
tyre pressures (Y page 157). G
Risk of accident
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, thes e
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident .

160 Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 110 Nm.
For safety reasons, Mercedes-Benz recom -
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every 5,000
km to 10,000 km depending on the degree of
tyre wear, provided that the vehicle has the
same size front and rear tyres. Do not reverse
the direction of tyre rotation.
The wear patterns on the front and rear tyres
differ depending on the operating conditions. Interchange the wheels before a clear wear
pattern has formed on the tyres. The fron
t
tyres typically wear more on the shoulders
and the rear tyres in the centre.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a whee l
is changed. Check the tyre pressure and, if
necessary, restart the tyre pressure loss
warning system*. Winter driving
Introduction to winter operation
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Ben z
Service Centre, at the onset of winter. Winter tyres
Use winter tyres at temperatures below +7 °
C and on snow or ice-covered roads. Only
then can the effect of the ABS and ES P®
driv-
ing systems be ensured in winter too.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
You must replace winter tyres with a trea d
depth of less than 4 mm immediately. They
are no longer suitable for winter use, in par-
ticular because they do not provide suffi-
cient grip. This could cause you to lose
control of your vehicle and cause an acci-
dent .
Always observe the maximum permitted
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permitted speed than that of Operation

the vehicle, affix an appropriate warning sign
in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
In such circumstances, you should also
restrict the maximum speed of the vehicle
using permanent Speedtronic 24
to the maxi-
mum permissible speed for winter tyres
( Y page 114). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired owing to unstable
cornering characteristics caused by the dif-
ferent tyres. You should therefore adap t
your driving style and drive carefully.
Have the spare wheel* replaced at th e
nearest qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified
specialist workshop . Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz or are of a correspondin g
standard of quality.
! Information about the use of snow chain-
compatible AMG winter tyres is applicable
for AMG tyres. Use of snow chains is only
permissible with these tyres.
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.
R Snow chains must not be fitted to emer-
gency spare wheels, e.g. a collapsibl e
emergency spare wheel.
R Fit snow chains to both rear wheels. Com-
ply with the manufacturer's installation
instructions.
! If snow chains are fitted to the front
wheels, they may come into contact with
the bodywork and axle components whe n
the vehicle is in motion and damage the
tyre or the vehicle. Do not exceed the maximum permissibl
e
speed of 50 km/h.
i You may wish to deactivate ES P®
when
pulling away with snow chains fitted
( Y page 51). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine
braking on a slippery road surface. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
