Important safety notes
G Warning A flat tyre severely impairs the driving, steer- ing and braking characteristics of the vehicle. There is a risk of an accident. Do not drive with a flat tyre. Immediately replace the flat tyre with your spare wheel, or consult a qualified specialist workshop. G WARNING Tyres, wheels or accessories which have not been approved by Mercedes-Benz for your vehicle, or are not used as they should be, can impair driving safety. As a result, you could cause an accident. Before purchasing and using them, enquire about their suitability, legal stipulations and factory recommenda- tions at a Mercedes-Benz Service Centre.
Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety. Before purchasing and using non-approved accessories, visit a qualified specialist work- shop and enquire about: Rsuitability Rlegal stipulations Rfactory recommendations
Information on the dimensions and types of wheels and tyres for your vehicle can be found in the "Wheel/tyre combinations" sec- tion (Y page 329). Information on air pressure for the tyres on your vehicle can be found: Ron the tyre pressure label on the fuel filler
flap
Rin the "Tyre pressure" section Modification work on the brake system and wheels is not permitted, nor is the use of spacer plates or brake dust shields. This inva- lidates the general operating permit for the vehicle. i Further information on wheels and tyres can be obtained at any qualified specialist workshop.
Operation Notes on driving Check the tyre pressures when the vehicle is heavily laden and, if necessary, adjust. While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tyres are damaged. If you sus- pect that a tyre is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tyres for damage. Hidden tyre damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tyres and wheels checked at a specialist workshop. When parking your vehicle, make sure that the tyres do not get deformed by the kerb or other obstacles. If it is necessary to drive over kerbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Oth- erwise, the tyres, particularly the sidewalls, may be damaged.
Regular checking of wheels and tyres RRegularly check the wheels and tyres of your vehicle for damage at least every 14
days, as well as after driving off-road or on rough roads. Damage includes cuts, punc- tures, cracks and bulges on tyres or severe corrosion or deformation on wheels, for example. Damaged wheels can cause a loss of tyre pressure.RRegularly check the tyre tread depth and the condition of the tread across the whole width of the tyre (Y page 319). In order to inspect the inner side of the tyre surface, turn the steering wheel to full lock.
RAll wheels must have a valve cap to protect the valve against dirt and moisture. Do not fit anything onto the valve other than the standard valve cap or a valve cap approved by Mercedes-Benz for your vehicle. Do not fit anything onto the valve, such as tyre pressure monitoring systems.
RYou should regularly check the pressure of
all your tyres including the spare wheel, particularly prior to long trips. Adjust the tyre pressure as necessary (Y page 324). The service life of tyres depends on various factors, including the following: Rdriving style Rtyre pressure Rtyre mileage
Tyre tread G WARNING Please keep in mind that: Rtyre grip decreases rapidly on wet roads when the tread depth is less than 3 mm. Thus, you should replace tyres that have insufficient tread.
Rwinter tyres should be replaced when the tread depth is 4 mm or less, as they no lon- ger provide adequate grip.
Rthe tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
Winter operation 319
depth and the condition of the tread across the entire width of all tyres. If necessary, turn the front wheels to full lock in order to inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi- cle and cause an accident due to the reduced grip of the tyres on the road.
Selecting, fitting and replacing tyres ROnly fit tyres and wheels of the same type
and make.
ROnly fit approved tyres of the correct size
onto the wheels.
RTyres are supplied with a protective layer from the factory. Run in new tyres at mod- erate speeds for the first 100 km. They only reach their full performance after this dis- tance.
RDo not drive with tyres which have too little
tread depth. This otherwise significantly reduces the traction on wet roads (aqua- planing).
RReplace the tyres after six years at the lat- est, regardless of wear. This also applies to the spare wheel.
Winter operation General notes Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 325).
Driving with summer tyres At temperatures below +7 †, summer tyres lose elasticity and therefore traction and braking power. Change the tyres on your vehi- cle to M+S tyres. Using summer tyres at very cold temperatures could cause tears to form, thereby damaging the tyres permanently.
320 Winter operation
Mercedes-Benz cannot accept responsibility for this type of damage.
M+S tyres G WARNING M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they do not provide sufficient traction. There is a risk of accident. M+S tyres with a tread depth of less than 4 mm must be replaced. G WARNING The spare wheel and M+S tyres have different tyre characteristics. Driving characteristics can be severely impaired when you fit the spare wheel. There is a risk of an accident. You should therefore adapt your driving style and drive carefully. Have the spare wheel replaced with a new wheel with an M+S tyre at the nearest qualified specialist workshop.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified by the M+S marking. Only winter tyres bearing the i snowflake symbol in addition to the M+S marking pro- vide the best possible grip in wintry road con- ditions. Only these tyres will allow driving safety systems such as ABS and ESP® to function optimally in winter, as these tyres have been designed specifically for driving on snow. Use M+S tyres of the same make and tread on all wheels to maintain safe handling char- acteristics. Always observe the maximum permissible speed specified for the M+S tyres you have fitted. If you fit M+S tyres that have a lower maxi- mum permissible speed than that of the vehi- cle, affix an appropriate warning sign in the driver's field of vision. This can be obtained at a qualified specialist workshop.
Under these circumstances, you should also restrict the maximum speed of the vehicle using variable SPEEDTRONIC so that it does not exceed the maximum permissible speed for the M+S tyres(Y page 178). When you have fitted the M+S tyres: X Check the tyre pressures (Y page 323). X Restart the tyre pressure monitor
(Y page 324).
i You can obtain information about winter
tyres that have been approved by Mercedes-Benz especially for your vehicle at any Mercedes-Benz Service Centre.
i For further information about tyres, see
(Y page 329).
Snow chains ! Information about the use of snow chain compatible AMG winter tyres is applicable for AMG tyres. Use of snow chains is only permissible with these tyres.
For safety reasons, Mercedes-Benz recom- mends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or that are of a corre- sponding standard of quality. Ronly use snow chains when the road sur- face is completely snow-covered. Remove the snow chains as soon as possible when you come to road that is not snow-covered.
Rlocal regulations may restrict the use of
snow chains. Observe the appropriate reg- ulations if you wish to fit snow chains.
RDo not exceed the maximum permissible
speed of 50 km/h.
If you intend to fit snow chains, please bear the following points in mind: Rsnow chains cannot be fitted to all wheel/
tyre combinations (Y page 62).
Rfit the snow chains on all four wheels for maximum tractive power and driving sta- bility. Observe the manufacturer's fitting instructions.
i You may wish to deactivate
ESP®(Y page 62) when pulling away with snow chains fitted. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cut- ting action).
Tyre pressure Tyre pressure specifications Important safety notes G WARNING Underinflated or overinflated tyres pose the following risks: Rthe tyres may burst, especially as the load
and vehicle speed increase.
Rthe tyres may wear excessively and/or unevenly, which may greatly impair tyre traction.
Rthe driving characteristics, as well as steer- ing and braking, may be greatly impaired.
There is a risk of an accident. Observe the recommended tyre pressure and check the tyre pressure of all the tyres includ- ing the spare wheel: Rat least every two weeks Rwhen the load changes Rbefore embarking on a longer journey Rfor changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G WARNING If you fit unsuitable accessories onto tyre valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure loss. Due to their design, retrofitted tyre pres- sure monitors keep the tyre valve open. This can also result in tyre pressure loss. There is a risk of accident. Only screw standard valve caps or valve caps specifically provided by Mercedes-Benz for your vehicle onto the tyre valve.
Tyre pressure 321
G WARNING If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged. Tyre pressure that is too low may result in a tyre blow-out. There is a risk of accident. RCheck the tyre for foreign objects. RCheck whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con- tact a qualified specialist workshop. H Environmental note Check the tyre pressure regularly, at least every 14 days.
General notes You will find a table of tyre pressures for var- ious operating conditions on the inside of your vehicle's fuel filler flap. Operation with a trailer: the applicable value for the rear tyres is the maximum tyre pressure value stated in the table inside the fuel filler flap. The table inside the fuel filler flap may state tyre pressures for different load conditions. These are defined in the table as different numbers of passengers and amounts of lug- gage. The actual number of seats may vary – for more information, please refer to the vehi- cle's registration documents. If tyre sizes are not specified, the tyre pres- sures stated on the tyre pressure information label apply for all tyres approved for this vehi- cle.
322 Tyre pressure
Tyre pressure table
If a tyre size precedes a tyre pressure, the tyre pressure information following is only valid for that tyre size.
Instead of the complete tyre size, the rim diameter alone, for example R16, may be lis- ted.
Rim diameter : is part of the tyre size and can be found on the tyre sidewall. Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure. On vehicles fitted with the electronic tyre pressure monitor, the tyre pressure can be checked using the on-board computer. If possible, only correct tyre pressures when the tyres are cold. The tyres are cold: Rif the vehicle has been parked with the tyres
out of direct sunlight for at least three hours and
Rif the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the speed you are driving at and the load on the tyres, the tyre temperature and thus the tyre pressure change by approximately 10 kPa (0.1 bar/1.5 psi) per 10 †. Take this into account when checking the pressure of warm tyres. Only correct the tyre pressure if it is too low for the current operating conditions. Driving with tyre pressure that is too high or too low can: Rshorten the service life of the tyres Rcause increased tyre damage Rhave a negative effect on handling charac-
teristics and thus the driving safety (e.g. aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you good ride comfort characteristics. However, you can also use the values given for higher loads. These are permissible and will not adversely affect the running of the vehicle.
Checking the tyre pressures Important safety notes Observe the notes on tyre pressure: (Y page 321). Information on air pressure for the tyres on your vehicle can be found: Ron the vehicle's tyre and loading informa-
tion table on the B-pillar (Y page 322)
Ron the tyre pressure label on the fuel filler
flap (Y page 322)
Rin the "Tyre pressure information" section Rin the "Tyre pressure information" section
(Y page 321)
Checking the tyre pressure manually To determine and set the correct tyre pres- sure, proceed as follows: X Remove the valve cap of the tyre that is to
be checked.
X Press the tyre pressure gauge securely
onto the valve.
X Read the tyre pressure and compare it with
the recommended value on the tyre and loading information table on the B-pillar on the driver's side of your vehicle (Y page 322).
X The tyre pressure is too low: increase the tyre pressure to the recommended value. X The tyre pressure is too high: press down the metal pin in the valve using the tip of a pen, for example. Air is released from the tyre.
X Check the tyre pressure again with the tyre
pressure gauge.
Tyre pressure 323
X Screw the valve cap onto the valve. X Repeat these steps for the other tyres.
Tyre pressure monitor 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 321). 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 324). 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 321). 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 abrupt steering manoeuvres. 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 when the pressure drops in one or more of the tyres. The tyre pressure monitor only func- tions if the correct sensors are fitted to all wheels. Information on tyre pressures is displayed in the multifunction display. After a few minutes of driving, the current tyre pressure of each tyre is shown in the multifunction display. The tyre pressure values indicated by the on- board computer may differ from those meas-
324 Tyre pressure
ured at a filling station with 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 val- ues 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 tyre pressure electronically X Make sure that the key is in position 2
(Y page 143)in the ignition lock. X Press the = or ; button on the steer- ing wheel to select the Serv. 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 message Tyre pressures will be displayed after a few minutes of driving 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 is fitted, the system may continue to show the tyre pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the spare tyre is fitted is not the same as the spare tyre's current tyre pressure.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a signifi- cant pressure loss on one or more tyres, a warning message is shown in the multifunc- tion display. A warning tone also sounds and the tyre pressure warning lamp lights up in the instrument cluster. Each tyre that is affected by a significant loss of pressure is highlighted in the pressure dis- play. X If the Please correct tyre pres‐ surePlease correct tyre pressure message appears in the multifunction dis- play, check the tyre pressure on all four wheels and correct it if necessary.
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. 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 321).
X Make sure that the key is in position 2
(Y page 143) in the ignition lock. X Press the = or ; button on the steer- ing wheel to select the Serv. 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.
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 The "Breakdown assistance" section (Y page 305) contains information and notes on how to deal with a flat tyre.
Interchanging the wheels G WARNING Interchange the front and rear wheels only if they have the same dimensions, for example size, offset, etc. Have the tightening torque checked at a quali- fied specialist workshop after a wheel is changed. 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 correct size which have been approved for Mercedes-Benz vehicles.
! 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. Always pay attention to the instructions and safety notices in the section on "Wheel changing and spare wheel fitting" (Y page 326). 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.
326 Changing a wheel
On vehicles that have the same size front and rear wheels, you can interchange the wheels every 5000 km 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 a wheel is interchanged. Check the tyre pressure and reactivate the tyre pressure monitor (Y page 323) if necessary.
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. You may fit the spare wheel against the direc- tion of rotation. Observe the time restriction on use as well as the speed limitation speci- fied on the spare wheel.
Storing wheels Store tyres that are not being used in a cool, dry and preferably dark place. Protect the tyres against oil, grease, petrol and diesel.
Cleaning the wheels G WARNING Do not use high-pressure cleaners with circu- lar-jet nozzles (dirt grinders) to clean your vehicle, in particular the tyres. You could oth- erwise damage the tyres and cause an acci- dent.

Securing the vehicle against rolling away 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.
X On 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 inserting wheel chocks. Never disen- gage 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 tailgate

X Unscrew the wheel bolts. X Remove the wheel.
Fitting a new wheel G WARNING If a wheel hub thread is damaged, do not drive the vehicle any further. Contact a qualified specialist workshop. G WARNING 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. Other wheel bolts could work loose or damage the brake system. Do not tighten the wheel bolts completely while the vehicle is still jacked up. The vehicle could topple off the jack.

Wheel and tyre combinations General notes ! For safety reasons, Mercedes-Benz rec- ommends that you only use tyres, wheels and accessories which have been approved by Mercedes-Benz specifically for your vehicle. These tyres have been specially adapted for use with the driving safety sys- tems, such as ABS or ESP®. 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 Mercedes-Benz Service Centre.
! 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.

G WARNING Driving safety may be impaired if non- approved parts, tyres and wheels or safety- relevant accessories are used. This could lead to malfunctions in safety-rel- evant systems, e.g. the brake system. This could cause you to lose control of your vehicle and cause an accident. For this reason, Mercedes-Benz recommends that you use genuine Mercedes-Benz parts or parts of equal quality. Only use tyres, wheels and accessories that have been specifically approved for your vehicle.
H Environmental note Daimler AG also supplies reconditioned assemblies and parts which are of the same quality as new parts. For these, the same war- ranty applies as for new parts.
! The use of non-approved parts could affect your vehicle's operating safety. Therefore, Mercedes-Benz recommends genuine Mercedes-Benz parts and conver- sion parts and accessories that have been approved for your vehicle.
! Airbags and seat belt tensioners, as well
as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars Rdoor sills Rseats Rdashboard Rinstrument cluster Rcentre console Do not install accessories such as audio systems in these areas. Do not carry out repairs or welding. You could impair the operating efficiency of the restraint sys- tems. Have accessories retrofitted at a qualified specialist workshop.
Mercedes-Benz tests genuine parts and con- version parts and accessories that have been specifically approved for your vehicle for their reliability, safety and suitability. Despite ongoing market research, Mercedes-Benz is unable to assess other parts. Mercedes-Benz accepts no responsibility for the use of parts that have been independently or officially approved. In Germany, certain parts are only officially approved for installation or modification if they comply with legal requirements. This also applies to some other countries. All gen- uine Mercedes-Benz parts meet the approval requirements. The use of non-approved parts
may invalidate the vehicle's general operating permit. This is the case: Rif they cause a change of the vehicle type from that for which the vehicle's general operating permit was granted
Rif other road users could be endangered Rif the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) (Y page 336) and the engine num- ber (Y page 337) when ordering genuine Mercedes-Benz parts.
Vehicle electronics Tampering with the engine electron- ics G WARNING Always have work on the engine electronics and related components carried out at a quali- fied specialist workshop. Otherwise, the vehi- cle's operating safety could be affected.
! 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 of two-way radios and mobile phones (RF transmitters) G WARNING Incorrect retrofitting of RF transmitters can cause the vehicle electronics to malfunction. The vehicle's operating safety and thus your own safety are impaired. Have aftermarket radio frequency transmit- ting equipment installed at a qualified spe- cialist workshop.

Petrol (EN 228) Fuel grade ! Do not use diesel to refuel vehicles with a petrol engine. Even a small quantity of die- sel will damage the fuel injection system. ! Only refuel using unleaded petrol with at least 95 RON/85 MON that conforms to
European standard EN 228 or E DIN 51626-1 or an equivalent specification. Fuel with this specification may contain up to 10 % ethanol.
! Do not use the following:
RE85 (petrol with 85 % ethanol) RE100 (100 % ethanol) RM15 (petrol with 15 % methanol) RM85 (petrol with 85 % methanol) RM100 (100 % methanol) RPetrol with metallic additives RDiesel Do not mix these fuels with petrol, and do not use any additives. This can otherwise lead to engine damage. This does not include cleaning additives for the removal and prevention of residue build-up. Only cleaning additives recommended by Mercedes-Benz should be added to petrol, see "Additives". You can obtain further information from any Mercedes-Benz Service Centre.
! Use a filter when adding fuel from a fuel can. The fuel lines and/or the diesel injec- tion system could otherwise be blocked by particles from the fuel can.
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 As a temporary measure, if the recom-
mended fuel is not available, you may also use unleaded petrol with an octane rating of 91 RON/82.5 MON. This may reduce engine performance and increase fuel con- sumption. Avoid driving at full throttle. Information on refuelling (Y page 156).

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.Additives ! Do not refuel with low grade fuel and do not use fuel additives that have not been tested and approved for Mercedes-Benz vehicles. Otherwise the fuel system could malfunction or be damaged.
One of the major problems with low-grade fuel is the creation of carbon deposits during the process of burning fuel. Mercedes-Benz recommends that you use fuel brands that have additives. If you use fuels without these additives for a longer period of time, there may be a build-up
of carbon deposits. These will form especially on the inlet valves and in the combustion chamber. This could lead to engine running problems, e.g.: Rlonger engine warm-up phase Runeven idle Rengine noise Rmisfiring Rloss of power In areas where petrol with the required addi- tives is not available, carbon deposits can build up. In this case, Mercedes-Benz recom- mends the use of additives that have been approved for Mercedes-Benz vehicles; see http://bevo.mercedes-benz.com. 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 additive recommended by Mercedes-Benz (part no. A000989254510). You must observe the notes and mixing ratios specified on the container. Consult a Mercedes-Benz Service Centre to view a list of approved products. Observe the instructions for use in the product descrip- tion. Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine.
Diesel (EN 590, DIN 51628) Fuel grade G WARNING Vehicles with a diesel engine: 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.

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:Rmarine diesel Rheating oil Rbio-diesel Rvegetable oil Rpetrol Rparaffin Rkerosene Do not mix such fuels with diesel fuel and do not use any special additives. This can otherwise lead to engine damage. This does not include flow improver additives. For further information, see "Flow improv- ers".
! Vehicles with a diesel particle filter: in countries outside the EU, only refuel with low-sulphur Euro diesel with a sulphur con- tent under 50 ppm; otherwise the emission control system could be damaged.
! Vehicles without a diesel particle fil- ter: in countries where only diesel fuel with a high sulphur content is available, you will need to carry out your vehicle's oil change at shorter intervals. More information about the interval for oil change can be obtained from any qualified specialist workshop.
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. Information on refuelling (Y page 157). 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 specifi- cations outlined in EN 590. At unusually low 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 Flow improvers can be added to improve the cold resistance of diesel fuel. The effective- ness of flow improvers cannot be guaranteed with all fuels. Only use flow improvers tested and approved by Mercedes-Benz. During use, please observe the information on operation. Correct dosage and thorough mixing are deci- sive factors in ensuring improvement in low- temperature resistance. Under certain cir- cumstances, an excessive dosage may actually decrease low-temperature resist- ance and should therefore be avoided. Follow the manufacturer's dosing instructions. Mix the additive into the diesel in good time, before the flow characteristics of the diesel become insufficient. Otherwise, malfunctions can only be rectified by heating the entire fuel system, e.g. by parking in a heated garage. More information about recommended flow improvers can be obtained from any qualified specialist workshop.
AdBlue® General notes AdBlue® is a non-flammable, non-toxic, col- ourless, odourless and water-soluble fluid.
High outside temperatures If you open the AdBlue® tank cap, small amounts of ammonia vapour may be released. Ammonia vapours have a pungent odour and are particularly irritating to: Rskin Rmucous membranes Reyes You may experience a burning sensation in your eyes, nose and throat, as well as cough- ing and watering of the eyes. Do not inhale any ammonia vapours that may be released. Fill the AdBlue® tank only in well- ventilated areas.
Low outside temperatures AdBlue® freezes at a temperature of approx- imately -11 †. The vehicle is equipped with an AdBlue® preheating system at the factory. Winter operation can therefore be guaran- teed even at temperatures below -11 †.
Additives ! Only use AdBlue® in accordance with ISO 22241. Do not use additives with AdBlue® and do not dilute AdBlue® with water. This may destroy the BlueTEC exhaust gas after- treatment system.
Purity ! Impurities in AdBlue® (e.g. due to other service products, cleaning agents or dust) lead to: Rincreased emission values Rdamage to the catalytic converter
