Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Risk of fire and
explosion by improper handling of fuel.
You must avoid fire, open flames, smoking
and creating sparks. Switch off the ignition
before refueling and, if present, switch off
the auxiliary heating.
GWARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
RImmediately rinse the fuel off your skin
with soap and water.
RIf you get fuel into your eyes, immediately
rinse your eyes throughly with clean
water. Seek medical attention immedi-
ately.
RSeek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.

Information about Service
Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval dis-play has been inadvertently reset, this set-ting can be corrected at a qualified special-ist workshop.
Have service work carried out as describedin the Maintenance Booklet. This may other-wise lead to increased wear and damage tothe major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-ized Mercedes-Benz Center, will reset theASSYST PLUS service interval display after theservice work has been carried out. You canalso obtain further information on mainte-nance work, for example.
Special service requirements
The specified maintenance interval takes onlythe normal operation of the vehicle intoaccount. Service work will need to be per-formed more often if the vehicle is operatedunder arduous conditions or increased loads.
The ASSYST PLUS service interval display isonly an aid. The driver of the vehicle is respon-sible for whether service work will need to beperformed more frequently than required as aresult of the actual operating conditionsand/or loads.
Examples of arduous operating conditions:
Rregular city driving with frequent intermedi-ate stops
Rthe vehicle is primarily used to travel shortdistances
Rfrequent use in mountainous terrain or onpoor road surfaces
Rthe engine is often left idling for long peri-ods
Rparticularly dusty conditions, or if air-recir-culation mode is frequently used
In these or similar operating conditions, havethe interior filter, air filter, engine oil and oil fil-ter, for example, changed more frequently.Under arduous operating conditions, the tiresmust be checked more often. Further informa-tion can be obtained at a qualified specialistworkshop.
Driving abroad
An extensive Mercedes-Benz Service networkis also available in other countries. You canobtain further information from any authorizedMercedes-Benz Service Center.

Maintenance and care
Z

Clean the contact surfaces of the wheel andthe brake disc thoroughly every time a wheelis rotated. Check the tire pressure and, if nec-essary, restart the tire pressure loss warningsystem or the tire pressure monitor.
Direction of rotation
Tires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk ofhydroplaning. These advantages can only begained if the tires are installed correspondingto the direction of rotation.
An arrow on the sidewall of the tire indicatesits correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
XStop the vehicle on solid, non-slippery andlevel ground.
XApply the electric parking brake manually.
XBring the front wheels into the straight-ahead position.
XShift the transmission to position].
XSwitch off the engine.
XVehicles without KEYLESS-GO:removethe SmartKey from the ignition lock.
XVehicles with KEYLESS-GO:open the driv-er's door.The vehicle electronics now have status0.This is the same as the SmartKey havingbeen removed.
XVehicles with KEYLESS-GO:remove theStart/Stop button from the ignition lock(Ypage 118).
XIf included in the vehicle equipment, removethe tire-change tool kit from the vehicle.
XSafeguard the vehicle against rolling away.
iDue to differences in vehicle equipment,not all vehicles are equipped with a tire-change tool kit. For information on which
tools are required to perform a wheelchange on your vehicle, consult an author-ized Mercedes-Benz Center.
Necessary tire-changing tools can include,for example:
RJack
RWheel chock
RLug wrench
Securing the vehicle to prevent it from
rolling away
If your vehicle is equipped with a wheel chock,it can be found in the tire-change tool kit(Ypage 252).
The folding wheel chock is an additional safetymeasure to prevent the vehicle from rollingaway, for example when changing a wheel.
XFold both plates upwardsC.
XFold out lower plateD.
XGuide the lugs on the lower plate fully intothe openings in base plate

Do not mix such fuels with the fuel recom-mended for your vehicle.
!To ensure the longevity and full perform-ance of the engine, only premium-gradeunleaded gasoline must be used.
If standard unleaded gasoline is unavailableand you have to refuel with unleaded gaso-line of a lower grade, observe the followingprecautions:
ROnly fill the fuel tank to half full with regu-lar unleaded gasoline and fill the rest withpremium-grade unleaded gasoline as soonas possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and enginespeeds over 3,000 rpm.
You will usually find information about the fuelgrade on the fuel pump. If you cannot find thelabel on the fuel pump, ask the gas stationstaff.
iFor further information, consult a qualifiedspecialist workshop or visithttp://www.mbusa.com (USA only).
As a temporary measure, if the recommendedfuel is not available, you may also use regularunleaded gasoline with an octane rating of87 AKI/91 RON. This may reduce engine per-formance and increase fuel consumption.Avoid driving at full throttle and sudden accel-eration. Never refuel using gasoline with alower AKI.
iThe fuels you can use in your vehicle maydiffer from the information in the Operator'sManual depending on the country. The fuelsthat have been approved for your vehiclecan be found on the instruction label on theinside of the fuel filler flap.
Information on refueling (Ypage 133).
Additives in gasoline
!Operating the engine with fuel additivesadded later can lead to engine failure. Donot mix fuel additives with fuel. This doesnot include additives for the removal andprevention of residue buildup. gasoline mustonly be mixed with additives recommendedby Mercedes-Benz. Comply with the instruc-tions for use on the product label. Moreinformation about recommended additivescan be obtained from any authorizedMercedes-Benz Center.
Mercedes-Benz recommends that you usebranded fuels that have additives.
The fuel quality available in some countriesmay not be sufficient. Residue could build upin the fuel injection system as a result. In suchcases, and in consultation with an authorizedMercedes-Benz Center, the fuel may be mixedwith the cleaning additive recommended byMercedes-Benz. You must observe the notesand mixing ratios specified on the container.
Engine oil
General notes
!Do not use engine oil or an oil filter withspecifications deviating from thoseexpressly required for the prescribed serviceintervals. Do not change the engine oil or oilfilter in order to set replacement intervalslonger than those prescribed. This couldotherwise cause damage to the engine orexhaust gas aftertreatment.

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the
brake fluid is too low, vapor pockets may
form in the brake system when the brakes
are applied hard. This would impair braking
efficiency. There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the impor-tant safety notes on service products(Ypage 298).
The brake fluid change intervals can be foundin the Maintenance Booklet.
Only use brake fluid approved by Mercedes-Benz in accordance with MB-Freigabe or MB-Approval 331.0.

Important safety notes
GWARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck. Thoroughly
clean the antifreeze from components
before starting the engine.
