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 menu of the multi- function display.

Example: current tyre pressure display For further information on displaying this message, refer to the "Checking the tyre pres- sure electronically" section (Y page 354).

Tyre pressure 353

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 350). 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 is aligned to the reference values taught-in. Restart the tyre pressure monitor after adjusting to the cold tyre pressure (Y page 355). The current pressures are saved as new reference values. This will 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 350). 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 sudden steering movements. 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: Rif 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.

Rif the warning lamp flashes for around a

minute and then remains lit constantly, the tyre pressure monitor is malfunctioning. i In addition to the warning lamp, a mes- sage appears in the multifunction display.

354 Tyre pressure

Further information can be found on: RVehicles with a 4-button multifunction

steering wheel: (Y page 270).

RVehicles with a 12-button multifunction

steering wheel: (Y page 271).

If the tyre pressure monitor is malfunctioning, it may take more than ten minutes for the tyre pressure warning lamp to inform you of the malfunction by flashing for approximately one minute and then remaining 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.

Checking the tyre pressure electroni- cally X Make sure that the key is in position 2 in

the ignition lock (Y page 149). X Press the = or ; button on the steer- ing wheel to select the Service menu. X Press the 9 or : button to select Tyre pressure. X Press the a button.

The current tyre pressure for each wheel will be displayed in the multifunction dis- play. If the vehicle has been parked for over 20 minutes, the Tyre pressures will be displayed after a few minutes of driving message appears.

After a teach-in period, the tyre pressure monitor automatically recognises new wheels or new sensors. As long as a clear allocation of the tyre pressure values to the individual wheels is not possible, the Tyre pressure monitor active display mes- sage is shown instead of the tyre pressure display. The tyre pressures are already being monitored. i If a spare wheel/emergency spare wheel is fitted, for a few minutes the system may continue to show the tyre pressure of the wheel that has been removed. If this occurs, the value displayed for the position where the spare wheel/emergency spare wheel is fitted is not the same as the spare wheel/emergency spare wheel's current tyre pressure.

Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pres- sure loss in one or more tyres, a warning mes- sage is shown in the multifunction display and the yellow tyre pressure monitor warning light comes on. RIf the 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. RIf the 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. RIf the Tyre malfunction appears in the multifunction display, the tyre pressure in one or more tyres has dropped suddenly and the tyres must be checked.

Observe the instructions and safety notes in the display messages in the "Tyres" section (Y page 271). i If the wheel positions on the vehicle are interchanged, the tyre pressures may be displayed for the wrong positions for a

short time. This is rectified after a few minutes of driving and the tyre pressures are displayed for the correct 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. i You will find an overview of the menus on

(Y page 222).

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 350).

X Make sure that the key is in position 2 in

the ignition lock. X Press the = or ; button on the steer- ing wheel to select the Service menu. X Press the 9 or : button to select Tyre pressure. X Press the a button.

The multifunction display shows the cur- rent tyre pressure for the individual tyres or the Tyre pressures will be dis‐ played after a few minutes of driv‐ ing message. X Press the : button. The Use current pressures as new reference values message appears in the multifunction display.

Tyre pressure 355

If you wish to confirm the restart: X Press the a button. 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 a wheel Flat tyre You can find information on what to do in the event of flat tyre in the "Flat tyre" section (Y page 330). Information on driving with MOExtended tyres in the event of a flat tyre can be found under "Breakdown assistance" (Y page 330). Vehicles with an emergency spare wheel: in the event of a flat tyre, the emer- gency spare wheel is fitted according to the description under "Fitting a wheel" (Y page 357).

Interchanging the wheels G WARNING Interchanging the 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 a risk of acci- dent. Interchange front and rear wheels only if the wheels and tyres are of the same dimensions.

! On vehicles fitted with a tyre 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 a qualified spe- cialist workshop.

Interchanging the front and rear wheels of differing dimensions can render the general operating permit invalid. Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 357). The wear patterns on the front and rear tyres 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 the same size front and rear wheels, you can interchange the wheels every 5,000 to 10,000 km depending on the degree of tyre wear. Ensure the direction of rotation is maintained. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel 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 a specified direction of rotation have additional benefits, e.g. if there is a risk of aquaplaning. You will only gain these ben- efits if the correct direction of rotation is observed. An arrow on the sidewall of the tyre indicates its correct direction of rotation.

Storing wheels Store wheels in a cool, dry and preferably dark place if they are not being used. Protect the tyres against oil, grease, petrol and diesel.

Cleaning the wheels G WARNING The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the outside to tyres or chassis components. Com-

i Apart from some country-specific var-

iants, vehicles are not equipped with tyre- changing tools. Some tools for changing a wheel are specific to the vehicle. For more information on which tools are required to

If your vehicle is equipped with a wheel chock, it can be found in the tyre-change tool kit (Y page 329). The folding wheel chock is an additional securing measure to prevent the vehicle from rolling away, for example when changing a wheel. X Fold both plates upwards :. X Fold out lower plate ;. X Guide the lugs on the lower plate fully into

the openings in base plate =.

358 Fitting a wheel

Securing the vehicle on level ground X On level ground: place chocks or other suitable items under the front and rear of the wheel that is diagonally opposite the wheel you wish to change.

Securing the vehicle on slight downhill gradients X On light downhill gradients: place

chocks or other suitable items 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 a risk 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: Rto raise the vehicle, only use the vehicle-

specific jack that has been tested and approved by Mercedes-Benz. If the jack is used incorrectly, it could tip over while the vehicle is raised.

Rthe jack is designed only to raise and hold the vehicle for a short time while a wheel is being changed. It is not suited for per- forming maintenance work under the vehi- cle.

Ravoid changing the wheel on uphill and

downhill slopes.

Rbefore raising the vehicle, secure it from

rolling away by applying the parking brake and positioning wheel chocks. Never release the parking brake while the vehicle is raised.

Rthe jack must be placed on a firm, flat and

non-slip surface. On a loose surface, a large, load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be used, e.g. rubber mats.

Rdo not use wooden blocks or similar

objects as a jack underlay. Otherwise, the jack will not be able to achieve its load- bearing capacity due to the restricted height.

Rmake sure that the distance between the underside of the tyres and the ground does not exceed 3 cm.

Rnever place your hands or feet under the

raised vehicle.

Rnever lie under the raised vehicle. Rnever start the engine when the vehicle is

raised.

Rnever open or close a door or the boot lid

when the vehicle is raised.

Rmake sure that no persons are present in

the vehicle when the vehicle is raised.

X Using wheel wrench :, loosen the bolts on the wheel you wish to change by about one full turn. Do not unscrew the bolts com- pletely.

X Make sure that the base of the jack is posi-

tioned vertically under the jacking point. X Turn crank ? clockwise until jack = sits

completely on jacking point ; and the base of the jack lies evenly on the ground. X Turn crank ? until the tyre is raised a max-

imum of 3 cm off the ground.

Removing a wheel ! Do not place wheel bolts in sand or dirt. The threads of the wheel bolts and wheel hubs could otherwise be damaged when the bolts are tightened.

The jacking points are located just behind the front wheel arches and just in front of the rear wheel arches (arrows).

X Unscrew the wheel bolts. X Remove the wheel.

X Position jack = at jacking point ;.

Fitting a new wheel G WARNING Oiled or greased wheel bolts or damaged wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could lose a wheel while driving. There is a risk of accident. Never oil or grease wheel bolts. In the event of damage to the threads, contact a qualified specialist workshop immediately. Have the damaged wheel bolts or hub threads replaced/renewed. Do not continue driving.

360 Fitting a wheel

G WARNING If you tighten the wheel bolts or wheel nuts when the vehicle is raised, the jack could tip over. There is a risk of injury. Only tighten the wheel bolts or wheel nuts when the vehicle is on the ground.

Always pay attention to the instructions and safety notices in "Changing a wheel" (Y page 356). Only use wheel bolts that have been designed for the wheel and the vehicle. For safety rea- sons, Mercedes-Benz recommends that you only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective wheel. Be sure to use the original-length wheel bolts when refitting the original wheel after it has been repaired.

X Clean the wheel and wheel hub contact

surfaces.

X Place the new wheel on the wheel hub and

push it on.

X Tighten the wheel bolts until they are fin-

ger-tight.

Lowering the vehicle G WARNING The wheels could work loose if the wheel nuts and bolts are not tightened to the specified tightening torque. There is a risk of accident.

Have the tightening torque immediately checked at a qualified specialist workshop after a wheel is changed.

X Turn the crank of the jack anti-clockwise

until the vehicle is once again standing firmly on the ground.

X Place the jack to one side. X Tighten the wheel bolts evenly in a cross-

wise pattern in the sequence indicated (: to A). The tightening torque must be 130 Nm.

X Turn the jack back to its initial position and store it together with the rest of the tyre- change tool kit in the stowage well under the boot floor.

X Transport the faulty wheel in the boot. or X Depending on the size of the wheel, you

may also be able to secure the faulty wheel in the spare wheel well. In this case, you will have to remove the stowage tray from the spare wheel well and stow it securely in the boot.

X Check the air pressure of the newly fitted

wheel and adjust accordingly. Observe the recommended tyre pressure (Y page 350).

i Vehicles with a tyre pressure control sys-

tem: all fitted wheels must be equipped with functioning sensors.

Wheel and tyre combinations General notes ! For safety reasons, Mercedes-Benz rec-

ommends that you only use tyres and wheels which have been approved by Mercedes-Benz specifically for your vehi- cle. These are specially adapted to the control systems, such as ABS or ESP® and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended (tyres featuring run-flat characteristics) RMO1 = Mercedes-Benz Original (only cer-

tain AMG tyres)

Mercedes-Benz Original Extended tyres may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tyres, wheels or accessories tes- ted and approved by Mercedes-Benz. Cer- tain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely affected. In addi- tion, when driving with a load, tyre dimen- sion variations could cause the tyres to come into contact with the bodywork and axle components. This could result in dam- age to the tyres or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tyres, wheels or accessories other than those tes- ted and approved. Further information about wheels, tyres and approved combinations can be obtained from any qualified specialist workshop.

! Retreaded tyres are neither tested nor recommended by Mercedes-Benz, since previous damage cannot always be detec- ted on retreaded tyres. As a result, Mercedes-Benz cannot guarantee vehicle safety if retreaded tyres are fitted. Do not fit used tyres if you have no information about their previous usage.

! Large wheels: the lower the section width for a certain wheel size, the lower the ride comfort is on poor road surfaces. Roll com- fort and suspension comfort are reduced and the risk of damage to the wheels and tyres as a result of driving over obstacles increases.

i You will find a table of tyre pressures on the inside of your vehicle's fuel filler flap. For further information on tyre pressure, see (Y page 350). Check tyre pressures regularly and only when the tyres are cold. i Notes on the vehicle equipment – always

fit the vehicle: Rwith tyres of the same size on a given axle

(left/right)

Rwith the same type of tyres at a given

time (summer tyres, winter tyres, MOExtended tyres)

i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you addi- tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified spe- cialist workshop.

Emergency spare wheel Important safety notes G WARNING The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel and the wheel to be replaced may differ. Fit- ting a spare wheel/emergency spare wheel may severely impair the driving characteris- tics. There is a risk of accident. To prevent hazardous situations: RAdapt your driving style accordingly and

drive carefully.

RNever fit more than one spare wheel/emer- gency spare wheel if the dimesions are dif- ferent to those of the wheel being replaced. ROnly use a spare wheel/emergency spare wheel briefly if the dimesions are different to those of the wheel being replaced.

RDo not switch off ESP®. RHave the spare wheel/emergency spare wheel in question replaced at the nearest qualified specialist workshop. Make sure that the wheel/tyre dimensions and tyre type are correct.

When using an emergency spare wheel or spare wheel of a different size, you must not exceed the maximum speed of 80 km/h. Snow chains must not be fitted to emergency spare wheels.

General notes You should regularly check the pressure of all your tyres, including the emergency spare wheel, particularly prior to long trips, and cor- rect the pressure as necessary (Y page 350). The applicable value is found on the wheel or under "Technical data" (Y page 361). i If you are driving with the collapsible emergency spare wheel fitted, the tyre pressure loss warning system or the tyre pressure monitor cannot function reliably. Only restart the tyre pressure loss warning system/tyre pressure monitor when the defective wheel has been replaced with a new wheel. Vehicles with tyre pressure monitor: after mounting an emergency spare wheel, the system may still display the tyre pres- sure of the removed wheel for a few minutes. The value displayed for the moun- ted emergency spare wheel is not the same as the current tyre pressure of the emer- gency spare wheel.

An emergency spare wheel may also be fitted against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel. Replace the tyres after six years at the latest, regardless of wear. This also applies to the emergency spare wheel.

9 Use of snow chains is not permitted. Observe the notes in the "Snow chains" section. 10 Observe notes on "Large wheels" in the "Wheel/tyre combinations" section.

Useful information

i This Owner's Manual describes all mod- els, series and optional equipment for your vehicle that were available at the time of going to press. National variations are pos- sible. Note that your vehicle may not be equipped with all of the functions descri- bed. This is also the case for systems and functions relevant to safety.

i Read the information on qualified special-

ist workshops: (Y page 28).

Information on technical data General notes You can find current technical data on the Internet at: http://www.mercedes-benz.com i The technical data was determined in accordance with EU Directives. All data applies to the vehicle's standard equip- ment. The data may therefore differ for vehicles with optional equipment. You can obtain further information from a Mercedes-Benz Service Centre.

Vehicle electronics Tampering with the engine electron- ics ! Only have work carried out on the engine electronics and its associated parts, such as control units, sensors and connector leads, at a qualified specialist workshop. Vehicle components may otherwise wear more quickly and the vehicle's operating permit may be invalidated.

Retrofitting two-way radios and mobile phones (RF transmitters) G WARNING If RF transmitters are tampered with or not properly retrofitted, the electromagnetic radi- ation they emit can interfere with the vehicle electronics. This may jeopardise the opera- tional safety of the vehicle. There is a risk of an accident. You should have all work on electrical and electronic components carried out at a quali- fied specialist workshop. G WARNING If you use the RF transmitter in the vehicle in an improper way, its electromagnetic radia- tion can disrupt vehicle electronics, e.g. if: Rthe RF transmitter is not connected to an

exterior aerial

Rthe exterior aerial is fitted incorrectly or is

not a low-reflection aerial

This can jeopardise the operating safety of the vehicle. There is a risk of an accident. Have the low-reflection exterior aerial fitted at a qualified specialist workshop. When oper- ating in the vehicle, always connect the RF transmitter to the low-reflection exterior aer- ial.

! The operating permit may be invalidated if the instructions for installation and use of RF transmitters are not observed. In particular, the following conditions must be complied with: Ronly approved wavebands may be used. Robserve the maximum permissible out-

put in these wavebands.

Ronly approved aerial positions may be

used.

Excessive levels of electromagnetic radiation may cause damage to your health and to the health of others. The use of an exterior aerial takes into consideration the scientific discus-

sion surrounding the possible health risk posed by electromagnetic fields. Observe the notes on operating mobile phones (Y page 302). The following aerial positions may be used for the correct installation of RF transmitters:

Approved aerial positions : Front roof area ; Rear roof area = Rear wing ? Boot lid i On vehicles with panorama sliding sun-

roof, fitting an aerial to the front or rear roof area is not permitted. On the rear wing, it is recommended that you position the aerial on the side of the vehicle closest to the centre of the road. Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting aftermarket radio frequency transmitting equipment") when retrofitting RF (radio fre- quency) transmitters. Comply with the legal requirements for add-on parts. If your vehicle has fittings for two-way radio equipment, use the power supply or aerial connections intended for use with the basic wiring. Be sure to observe the manufacturer's additional instructions when installing. Deviations with respect to wavebands, maxi- mum transmission outputs or aerial positions must be approved by Mercedes-Benz.

Petrol (EN 228, E DIN 51626-1) Fuel grade ! Do not use diesel to refuel vehicles with a petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, fuel can enter the fuel sys- tem. Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely.

! Only refuel using premium-grade unlea- ded petrol with at least 95 ROZ/85 MOZ, that conforms to European standard EN 228 or E DIN 51626–1 or an equivalent specification. Fuel of this specification can contain up to 10 % ethanol. Fuel that does not conform to EN 228 or E DIN 51626–1 can lead to increased wear and damage the engine and exhaust sys- tem.

! Only use the fuel recommended. Operat- ing the vehicle with other fuels can lead to engine failure.

! Do not use the following:

RE85 (petrol with 85% ethanol) RE100 (100% ethanol) RM15 (petrol with 15% methanol) RM30 (petrol with 30% methanol) RM85 (petrol with 85% methanol) RM100 (100% methanol) RPetrol with additives containing metal RDiesel Do not mix such fuels with the fuel recom- mended for your vehicle. Do not use addi- tives. This can otherwise lead to engine damage. This does not include cleaning additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by Mercedes- Benz; see "Additives". You can obtain fur-

ther information from any Mercedes-Benz Service Centre.

Usually you will find information about the fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling sta- tion staff. i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.

i C 180 BlueEFFICIENCY: as a temporary measure, if the recommended fuel is not available, you may also use unleaded petrol with an octane rating of 93 RON/83 MON. All other models: as a temporary meas- ure, if the recommended fuel is not availa- ble, you may also use unleaded petrol with an octane rating of 91 RON/82 MON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle.

i In some countries, the available petrol

may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced.

Information on refuelling (Y page 165). AMG vehicles ! Only refuel using super unleaded petrol with at least 98 RON/88 MON that con- forms to European standard EN 228 or an equivalent specification. You can otherwise impair engine output or damage the engine.

! Premium-grade unleaded petrol with an octane rating of 95 RON/85 MON may be used as a temporary measure if the recom- mended fuel is not available. This may reduce engine performance and increase fuel consumption. As much as possible, avoid driving at full throttle.

! Regular unleaded petrol with an octane rating of 91 RON/82.5 MON may also be used as a temporary measure if the recom- mended fuel is not available. Doing so results in noticeably higher fuel consumption, and the engine power output is noticeably reduced. Avoid driving at full throttle. If only regular unleaded petrol with an octane rating of 91 RON/82.5 MON or lower is available, you must have the vehi- cle adapted to this fuel at a qualified spe- cialist workshop.

i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel. C 350
! Only refuel using premium-grade sulphur- free unleaded petrol with at least 95 RON/ 85 MON that conforms to European stand- ard EN 228 or an equivalent specification. You could otherwise impair engine output or damage the emission control system. i In some countries, the available petrol

may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced.

Additives ! Operating the engine with fuel additives added later can lead to engine failure. Do not mix fuel additives with fuel. This does not include additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by Mercedes-Benz. Observe the instruc- tions for use in the product description. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre.

Mercedes-Benz recommends that you use fuel brands that have additives. The quality of the fuel available in some coun- tries may not be sufficient. Residue could build up as a result. In such cases, and in consultation with a Mercedes-Benz Service Centre, the petrol may be mixed with the cleaning additive recommended by Mercedes-Benz (part no. A000989254512). You must observe the notes and mixing ratios specified on the container.

Diesel (EN 590) Fuel grade G WARNING If you mix diesel fuel with petrol, the flash point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running, components in the exhaust system may over- heat unnoticed. There is a risk of fire. Never refuel with 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 lead to increased wear as well as damage to the engine and exhaust system. ! Do not use the following:
