(Y page 109).
Operation with atrailer: thea pplicable value
for th erear axle is th emaximum value stated in
th et yrep ressure table.
The tyr epressure table may also state tyr epres-
sures for differen tload conditions. Thes eare
defined in th etable as differen tnumbers of pas-
sengers and amounts of luggage. The actual
number of seat smay differ fro mthis.
If tyr esizes are not specified ,the tyrep ressures
stated on th etyrep ressure informatio nlabel
apply for all tyres approved for this vehicle. If one or mor
etyre sizes precedes atyre pres-
sure, the following tyre pressure information is
valido nly for that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not give any reliable indicatio nofthe tyre pres-
sure.
You can also check the tyre pressure using the
on-board computer.
If possible, correct tyre pressures only when the
tyres are cold. The tyres are cold:
R if the vehicl ehas 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
Dependin gonthe outside 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. Correct the tyre pres-
sure only if it is too low for the current operating
condition.
Drivin gwithatyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimum values that offer you good driving
comfor tcharacteristics.
However, you can also use the values given for
higher loads. These are permissible and will not
adversely affect the runnin gofthe vehicle. Tyre pressur
emonitor
General notes If
at yre pressure monitor is fitted, the vehicle's
wheelsh ave 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
functions only if the corresponding sensors are
fitted to all wheels.
Information on tyre pressures is shown on the
multifunction display. After afew minutes of
driving, the current tyre pressure of each wheel
is shown in the Serv.

You can ask for information regarding permitted
wheel/tyre combinations at aMercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres, wheels and
accessories which have been approved by
Mercedes-Benz for you rvehicle. These are
speciall yadapted to the various driving safety
systems, such as ABS or ESP ®
.
Only use the tyres, wheels and accessories
tested and recommende dbyMercedes-Benz.
Certain characteristics, such as handling,
vehicl enoise emissions, fuel consumption,
etc. may otherwise be adversely affected.
Other wheel sizes may caus ethe tyres to
come into contact with the vehicl ebody and
axle components, whe nunder load. This may
result in damage to the tyre or the vehicle.
Mercedes-Benz is not responsibl efor any
damage caused by using tyres, wheels or
accessories other than those recommended.
Informatio nontyres, wheels and permissible
combinations can be obtained at aqualified
specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommende dbyMercedes-Benz, since previ-
ous damage cannot alwaysbed etected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicl esafety if retreaded
tyres are fitted. Do not fit use dtyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Rol lcomfort
and suspension comfort are reduced and the risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommende dtyre pressures for various
operating conditions can be found on the tyre 246

components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality .Fuel that does not
conform to EN 590 can leadtoi ncreased wear
as wellasd amage to the engine and exhaust
system. !
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitablef or operation in colder
climatic conditions.

Engine oil
General notes When handling engin
eoil, observe the important
safety notes on service products (Y page 250).
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 correspond to the curren ttech-
nical 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 recom-
mends that you have the oil change carried out
at aq ualified specialist workshop. Mercedes-
Benz approval is indicated on the oil container

WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to aheavy load. This would impair brak-
ing efficiency. There is arisk of an accident.
Have the brake flui drenewe datthe prescri-
bed intervals.
Comply with the important safety notes for ser- vice products when handling brake fluid
(Y page2 50).
Only use brake flui dapproved by Mercedes-
