lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, will reset the ASSYST PLUS service interval display after
the service work has been carried out. You
can also obtain further information on main-
tenance work, for example.
Special service requirements The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R for frequent operation in mountainous ter-
rain or on poor road surfaces
R if the engine is often left idling for long peri-
ods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tyres
must be checked more frequently if the vehi-
cle is operated under increased loads. Fur-
ther information can be obtained at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
Driving abroad An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain further information from any
Mercedes-Benz Service Centre. Care

Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man- ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz. Washing the vehicle and cleaning the

Cleaning the exhaust tail pipes G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
Impurities combined with the effects of road
grit and corrosive environmental factors may cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in win- ter and after washing.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz. Interior care
Cleaning the display !
For cleaning, do not use any of the fol-
lowing:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display. X
Before cleaning the display, make sure that
it is switched off and has cooled down.

Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteris- tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.

characteristics)
General notes 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. The affected
tyre must not show any clearly visible dam-
age.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or tyre pressure monitor.
If a pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 295)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is approximately 80 km when the vehicle is
partially laden and approximately 30 km
when the vehicle is fully laden. 358
Flat tyreBreakdown assistance

The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
vehicle speed and the load on the tyres, the
tyre temperature and thus the tyre pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi) per 10 †. Take this into account
when checking the pressure of warm tyres.
Only correct the tyre pressure 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 a negative effect on handling charac-
teristics and thus driving safety (e.g. aqua-
planing)
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 andwill not adversely affect the running of the
vehicle.
The values on the tyre pressure information
label (fuel filler flap) for the vehicle in "parti-
ally laden" and "fully laden" conditions apply
when driving at maximum speed.
Despite the values stated on the tyre pressure
information label, for the vehicle with "parti-
ally laden up to 210 km/h" status, the val-
ues can be reduced as follows, without com-
promising safety:
R Ò20 kPa (Ò0.2 bar/Ò3 psi) for all models
This improves the ride comfort of your vehi-
cle; however, fuel consumption may increase slightly. Tyre pressure monitor
General notes 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 corresponding sensors are fitted to all
wheels.
Information on tyre pressures is shown in the multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre
is shown in the Service Servicemenu of the multi-
function display, see illustration (example). For information on the message display, refer
to the "Checking the tyre pressure electroni-
cally" section (Y page 382).
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 380). 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 isaligned to the reference values taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(Y page 383). The current pressures are
saved as new reference values. This will Tyre pressure
381Wheels and tyres Z

ensure that a warning message will only
appear 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 380).
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 tyre pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indicat- ing a pressure loss or malfunction. Depending
on how the warning lamp flashes or lights up, a tyre pressure that is too low or a malfunc-
tion in the tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the
tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure moni-
tor is not malfunctioning.
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 in the multifunction display. Observe
the information on display messages
(Y page 295).
It may take up to ten minutes for a malfunc-
tion of the tyre pressure monitor to be indi-
cated. A malfunction will be indicated by the
tyre pressure warning lamp flashing for
approximately one minute and then remain-
ing lit. When the fault has been rectified, the
tyre pressure warning 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 computer refer to those measured at
sea level. At high altitudes, the tyre pressure
values indicated 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
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.

sure loss in one or more tyres, a warning mes-
sage is shown in the multifunction display and the yellow tyre pressure monitor warning
lamp comes on.
R If the Please correct tyre pressure
Please correct tyre pressure
message appears in the multifunction dis-
play, the tyre pressure in at least one tyre is too low and must be corrected at the next
opportunity.
R If the Check tyre(s)
Check tyre(s) message appears in
the multifunction display, the tyre pressure
in one or more tyres has dropped signifi-
cantly and the tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears in the multifunction display, the
tyre pressure in one or more tyres has drop-
ped suddenly and the tyres must be
checked.
Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 295).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed for the wrong positions for a short time. After
a few minutes of driving, this is rectified and
the tyre pressures are displayed for the cor-
rect positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the tyre pressure monitor will automatically
detect the new reference values after you
have changed the tyre pressure. However,
you can also define reference values man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure values. X
Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.

Tyre pressure loss warning system
General 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.
You can recognise the tyre pressure loss
warning by the Run Flat Indicator Run Flat Indicator

(Y page 385).
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 380).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted 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
