G
WARNING
Interchangin gthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is arisk of acci-
dent. Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with atyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchangin gthe front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fittin gawheel" section (Y page 337).
The wear pattern sonthe front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before aclear wear
pattern has formed on the tyres. Frontt yres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000km to 10,000 km depending on
the degree of tyre wear. Maintain the direc-
tion of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time awheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor. Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correc tdirection of rotation is
observed.
An arrow on the sidewal lofthe tyre indicates
its correc tdirection of rotation. 336

Securing the vehicle on level ground
X
On level ground: place chocks or other
suitabl eitem sunder the front and rea rof
the whee ltha tisd iagonally opposite the
wheel you wish to change. Securing the vehicle on slight downhill gradients
X
On light downhill gradients: place
chocks or other suitablei tems in front of
the wheels of the front and rear axle.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is arisk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle. The following must be observed when raising
the vehicle:
R
to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ift he jack is
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for ashort time while awheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphilla nd
downhill slopes.
R before raising the vehicle, secure it from
rolling awaybya pplying the parking brake
and inserting wheel chocks. Never disen-
gage the parking brake while the vehicle is
raised.
R the jack must be placed on afirm, flat and
non-slip surface. On aloose surface, a
large, load-bearing underlay must be used.
On aslippery surface, anon-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as ajack underlay.O therwise, the
jack will no tbea ble to achiev eits load-
bearin gcapacity due to the restricted
height.
R mak esure that the distanc ebetween the
underside of the tyre sand the groun ddoes
not exceed 3cm.
R never place your hands or feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or clos eadoor or the boot lid
when the vehicle is raised.
R mak esure that no persons are present in
the vehicle when the vehicle is raised. 338

outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient. Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.
i Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow improvers
To improve the low-temperature resistanc eof
diesel fuel, aflow improver can be attached.
The effectiveness of aflow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. During use, please
observe the information on operation.
Correct dosage and sufficient mixing are deci-
sive in improving low-temperature resistance
with the flow improver. Overdosage can
potentially even decrease low-temperature
resistanc eand must therefor ebeavoided.
Follow the manufacturer's guidelines on dos-
age.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in aheated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop.
Fuel consumption information H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefor edepend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions You can minimise your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
document sare delivered with your vehicle.
The consumption figures were in each case
based on the currently applicabl eversion:
R for vehicles that comply with standards
up to and including the EURO 4standard,
in accordanc ewithEUD irective
80/1268/EEC
R for vehicles tha tcomply with or exceed
the EURO 5standard, in accordanc ewith
Regulatio n(EC )N o. 715/2007
Deviation sfrom these values may occur
under normal operating conditions. Engine oil
General notes The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspon dtothe current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Servic eCentre. Mercedes-
Benz recommends that you have the oil
change carried out at aqualified specialist
workshop. Mercedes-Benz approval is indica- Service products and capacities

shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regularo il
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid
G
WARNING
Over aperiod of time, the brak efluid absorbs
moisture fro mthe air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
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 according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid renewed regularly at
aq ualified specialist workshop. Coolant
Important safety notes G
WARNING
Antifreeze is highly flammable. Fire, naked
flames and smoking are prohibited when han-
dling antifreeze.
If antifreeze comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any antifreeze on hot
engine parts. !
Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherw ised amage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
Or contact aqualified specialist workshop.
! Always use asuitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio nand
overheating.
! The engine cooling system is filled with
coolant, which must be renewe dafter
15 years or after 250,000 kilometres at the
latest.
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant during operation willbea pprox-
imatel y130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. Thi swillp rotect the engine
cooling system against freezing dow nto
approximately -3 7†.
R not exceed 55% (antifreeze protection
down to -45 †). Hea twill otherwise not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosio ninhibitor. Mercedes-Benz recom-
mend sana ntifreeze/corrosion inhibito rcon-
centrate in accordanc ewith MB Specifica-
