If you wish to define the new reference values
manually:
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.
Also observe the notes in the section on
tyre pressures (Y page 305).
X Make sure that the key is in position 2in
the ignition lock.
X Use the =or; button on the steer-
ing wheel to select the Service menu.

X Press the abutton.
The current tyre pressure of the individual
wheels is displayed in the multifunction dis-
play or the Tyre pressures will be displayed after a few minutes of
driving message appears.
X Press the :button.

in the multifunction display.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored. Changing

The "Breakdown assistance" section
(Y page 281) contains information and notes
on how to deal with a fla ttyre. It also provides
instructions on changing a wheel or fitting the
spare wheel or emergency spare wheel. Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions :for example
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 recom-
mends 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 spe-
cialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Ben zvehicles.
The wear patterns on the fron tand rea rtyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have th esame size fron tand
rea rwheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Cleant he contact surfaces of the wheel and

is interchanged. Check the tyre pressure and, Changing

Important safety notes
Service products include the following:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Vehicle components and their respective
lubricants must match. Mercedes-Benz rec-
ommends that you use products that have
been tested and specially approved by
Mercedes-Benz. These products are listed in
this Mercedes-Benz Owner's Manual in the
relevant section.
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51)
Other designations or recommendations that
relate to a level of quality or a specification in
accordance with an MB Sheet number (such
as MB 229.5) have not necessarily been
approved by Mercedes-Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of any
service products, please observe the relevant
regulations, as you could otherwise endanger
yourself and others.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your eyes
or open wounds. See a doctor immediately if
any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuel
Important safety notes G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
Risk of injury
Do not come into contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours.

Brake fluid
G
Ris
kofa ccident
The brake fluid constantly absorbs moisture
from the air; this lower sits boiling point.
If the boiling point of the brake fluid is too low,
vapour pockets may for minthe 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-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre.
i There is usually a notice in the engine
compartmentt o remind you when the next
brake fluid change is due. Coolant
Important safety notes The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point i
When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Servic eProducts, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .You can
also consult a Mercedes-Benz Service
Centre.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correc tconcentration, the boiling point of
the coolant will be around 130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protec tthe engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to 45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Ben zrecom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The engine cooling system is filled with
coolant that must be renewed after 15
years, or after 250,000 km at the latest. 322

The 24 GHz radar senso rsystem requires separate approval fo reach country. When you are
driving in a country in which the radar sensor system is no tapproved, you must deactivate
the system using the on-board computer (Y page 210). The current country overview can be
obtained from a Mercedes-Benz Service Centre.
Vehicles with navigation system: the radar sensorsystem is deactivated automatically near
radio telescope facilities.
