Information about driving with an emergency
spare wheel (Y page 375). Snow chains
G
WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R never fit snow chains on the front wheels
R fit snow chains to the rear wheels in pairs.
! You must drive at a raised vehicle level if
snow chains have been fitted. The vehicle
could otherwise be damaged. Observe the
notes in the "AIRMATIC package" section.
! When driving with snow chains fitted, do not
use the ADS sport mode (Adaptive Damping
System). The vehicle could otherwise be dam-
aged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have been approved for Mercedes-Benz or that are of
an equivalent standard of quality. For more
information, please contact a qualified special-
ist workshop.
Fit the snow chains on all driven wheels for max-
imum tractive power and driving stability. If you
own snow chains for two driven wheels only, fit the snow chains to the wheels on the rear axle.
The vehicle then remains more stable under
braking.
If you wish to fit snow chains, please bear the
following points in mind:
R snow chains cannot be fitted to all wheel/tyre
combinations. Permitted wheel/tyre combi-
nations (Y page 374).
R use snow chains only if the road surface is
completely snow-covered. Remove the snow chains as soon as possible when you come to
a road that is not snow-covered.
R local regulations may restrict the use of snow
chains. Observe the appropriate regulations if you wish to fit snow chains.
R do not exceed the maximum permissible
speed of 50 km/h.
R never use Parking Pilot when snow chains are
fitted (Y page 204).
You may wish to deactivate ESP ®
when pulling
away with snow chains fitted (Y page 73). This
allows the wheels to spin in a controlled manner, achieving increased propulsive force (cut).

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 check the 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- 364

Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pressure
loss warning system monitors the set tyre pres-
sure 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 display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active
Run Flat Indicator active
Restart with OK
Restart with OK message which appears in
the Serv.
Serv. menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 366).
Important safety notes 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 364).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure 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 (corner-
ing 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 vehi-
cle 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 rec-
ommended tyre pressures can be found in the
tyre pressure 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.

The tyre pressure values stored at the last
restart will continue to be monitored. Tyre pressure monitor
General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor 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 pres- sure monitor functions only if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown on the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Serv. Serv.menu of the multifunction
display, see illustration (example). For information on the message display, refer to
the "Checking the tyre pressure electronically"
section (Y page 367).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 364). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If
a substantial loss of pressure occurs, the warn- ing threshold for the warning message is aligned
to the taught-in reference values. Restart the
tyre pressure monitor after adjusting to the cold tyre pressure (Y page 368). The current pres-
sures are saved as new reference values. This
ensures that a warning message appears only if the tyre pressure 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 364). 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 air, bring the vehicle to a halt by
braking carefully. Avoid abrupt steering
manoeuvres.
The tyre pressure monitor has a yellow warning lamp in the instrument cluster for indicating a
pressure loss or malfunction. Depending on how
the warning lamp flashes or lights up, a tyre
pressure that is too low or a malfunction in the
tyre pressure monitor is indicated:
R If the warning lamp is lit continuously, the tyre
pressure on one or more tyres is significantly too low. The tyre pressure monitor is not mal-
functioning.
R If the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears on the multifunction display. Observe
the information on display messages
(Y page 283).
It may take up to ten minutes for a malfunction
of the tyre pressure monitor to be indicated. A
malfunction will be indicated by the tyre pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
fault has been rectified, the tyre pressure warn- ing lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station using a pressure gauge.
The tyre pressures shown by the on-board com- puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interference from radio transmit- ting equipment (e.g. cordless headphones, two-
way radios) that may be being operated in or
near the vehicle.

The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system or the tyre pressure monitor
(Y page 366). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tyres
against oil, grease, petrol and diesel. Fitting a wheel

over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
It is imperative to observe the instructions and
safety notes on "Changing a wheel"
(Y page 369).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel.
! Always use wheel bolts
;to fit the collaps-
ible emergency spare wheel. Using other
wheel bolts to fit the collapsible emergency

If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys-
tem or the tyre pressure monitor cannot func-
tion reliably. Only restart the tyre pressure loss
warning system or tyre pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure monitor: all fit-
ted wheels must be equipped with functioning
sensors. Wheel and tyre combinations
You can ask for information regarding permitted wheel/tyre combinations at a Mercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or
accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures for various
operating conditions can be found in the tyre
pressure table inside the fuel filler flap. Further
information on tyre pressure (Y page 364).
Check tyre pressures regularly and only when
the tyres are cold.
Notes on the vehicle equipment – always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. 374

Emergency spare wheel
Important safety notes
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 prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions 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.
! Mercedes-AMG vehicles with
"Minispare" emergency spare wheel: only
use the "Minispare" emergency spare wheel
on the rear axle. If you fit the "Minispare"
emergency spare wheel to the front axle, the braking system could be damaged.
If a tyre on the front axle is damaged, an
undamaged wheel on the rear axle must be
replaced first with the "Minispare" emergency
spare wheel. The damaged wheel on the front
axle can then be replaced by the undamaged wheel from the rear axle.
You must observe the instruction label on the"Minispare" emergency spare wheel.
When using an emergency spare wheel or spare wheel of a different size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted emergency spare wheels at a Mercedes-Benz
Service Centre.
Fitting the emergency spare wheel is described under "Fitting a wheel" (Y page 370).
You should check the pressure of all your tyres, including the emergency spare wheel, regularly
as well as prior to long trips, and correct the
pressure as necessary (Y page 364). The value
on the wheel is valid.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specified on the emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys- tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn-
ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: after an
emergency spare wheel has been fitted, the sys- tem may still display the tyre pressure of the
removed wheel for a few minutes. The value dis-
played for the position where the emergency
spare wheel is fitted is not the same as the cur- rent tyre pressure of the emergency spare
wheel. Removing/stowing the emergency
spare wheel
Vehicles with a "Minispare" emergency
spare wheel under the luggage com-
partment floor Observe the instructions and safety notes in the
