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.

Important safety notes G WARNING When driving in emergency mode, the driving characteristics deteriorate, e.g. when corner- ing, accelerating quickly and when braking. There is a risk of accident. Do not exceed the stated maximum speed. Avoid abrupt steering and driving manoeu- vres, and driving over obstacles (kerbs, pot- holes, off-road). This applies in particular to a laden vehicle. Stop driving in emergency mode if: Ryou hear banging noises. Rthe vehicle starts to shake. Ryou see smoke and smell rubber. RESP® is intervening constantly. Rthere are tears in the sidewalls of the tyre. After driving in emergency mode, have the wheel rims checked at a qualified specialist workshop with regard to their further use. The faulty tyre must be replaced.

TIREFIT kit Important safety notes TIREFIT is a tyre sealant. You can use TIREFIT to seal punctures of up to 4 mm, particularly those in the tyre tread. You can use TIREFIT at outside temperatures down to Ò20 †.

If the pressure loss warning message appears in the multifunction display: RVehicles with a 4-button multifunction

steering wheel: observe the instructions in the display mes- sages (Y page 270).

RVehicles with a 12-button multifunc-

tion steering wheel: observe the instructions in the display mes- sages (Y page 271).

Rcheck the tyre for damage. Rif driving on, observe the following notes. The maximum driving distance is approx- imately 80 km when the vehicle is partially laden and approximately 30 km when the vehicle is fully laden. In addition to the vehicle load, the driving dis- tance possible depends upon: Rspeed Rroad condition Routside temperature The driving distance possible in run-flat mode may be reduced by extreme driving condi- tions/manoeuvres, or it can be increased through a moderate style of driving. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tyre pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 80 km/h. i When replacing one or all tyres, make

sure that you use only: Rthe tyre size specified for the vehicle and Rtyre(s) marked "MOExtended" If a tyre has gone flat and cannot be replaced with an MOExtended tyre, a standard tyre may be used as a temporary measure. Make sure that you use the proper size and type (summer or winter tyre).

i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory.

G WARNING In the following situations, the tyre sealant is unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly: Rthere are cuts or punctures in the tyre

larger than those mentioned above.

Rthe wheel rim is damaged. Ryou have driven at very low tyre pressures

or on a flat tyre.

There is a risk of an accident. Do not drive any further. Contact a qualified specialist workshop. G WARNING The tyre sealant is harmful and causes irrita- tion. It must not come into contact with your skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tyre sealant away from children. There is a risk of injury. If you come into contact with the tyre sealant, observe the following: RRinse off the tyre sealant from your skin

immediately with water.

ist workshops: (Y page 28).

Important safety notes

G WARNING If wheels and tyres of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an acci- dent. Always replace wheels and tyres with those that fulfil the specifications of the original part. When replacing wheels, make sure to fit the correct: Rdesignation Rtype When replacing tyres, make sure to fit the correct: Rdesignation Rmanufacturer Rtype G WARNING A flat tyre severely impairs the driving, steer- ing and braking characteristics of the vehicle. There is a risk of accident. Tyres without run-flat characteristics: Rdo not drive with a flat tyre. Rimmediately replace the flat tyre with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop.

Tyres with run-flat characteristics: Rpay attention to the information and warn-

ing notices on MOExtended tyres (tyres with run-flat characteristics).

Accessories that are not approved for your vehicle by Mercedes-Benz or that are not being used correctly can impair 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 361). 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. Modification work on the brake system and wheels is not permitted. The use of wheel spacers or brake dust shields is not permit- ted. This invalidates the general operating permit for the vehicle. i Further information on wheels and tyres can be obtained at any qualified specialist workshop.

Operation Information on driving RCheck the tyre pressures when the vehicle is heavily laden and, if necessary, adjust. RWhile driving, pay attention to vibrations, noises and unusual handling characteris- tics, e.g. pulling to one side. This may indi- cate that the wheels or tyres are damaged. If you suspect 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 qualified specialist workshop. RWhen 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 eleva- tions, try to do so at an obtuse angle. Oth- erwise, the tyres, particularly the sidewalls, can get damaged.

Regular checking of wheels and tyres G WARNING Damaged tyres can cause tyre inflation pres- sure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tyres regularly for signs of damage and replace any damaged tyres immediately.

RRegularly check the wheels and tyres of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can

Operation 347

cause a loss of tyre pressure. Pay particular attention to damage such as: - cuts in the tyres - punctures - bulges on tyres - deformation or severe corrosion on

tears in the tyres

wheels

RRegularly check the tyre tread depth and the condition of the tread across the whole width of the tyre (Y page 347). If neces- sary, turn the front wheels to full lock in order to inspect the inner side of the tyre surface.

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 other valve caps approved by Mercedes-Benz for your vehi- cle. Do not fit any other valve caps or sys- tems, e.g. tyre pressure monitoring sys- tems.

RRegularly check the pressure of all the tyres including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 350).

Observe the notes on the emergency spare wheel (Y page 365). The service life of tyres depends on various factors, including the following: RDriving style RTyre pressure RMileage

Important safety notes on the tyre tread G WARNING Insufficient tyre tread will reduce tyre trac- tion. The tyre is no longer able to dissipate water. This means that on wet road surfaces, the risk of aquaplaning increases, in particular

348 Winter operation

where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ- ent locations on the tyre tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tyres. Minimum tyre tread depth for: Rsummer tyres: 3 mm RM+S tyres: 4 mm For safety reasons, replace the tyres before the legally prescribed limit for the minimum tyre tread depth is reached..

Selecting, fitting and replacing tyres ROnly fit tyres and wheels of the same type

and make. Exception: it is permissible to fit a different type or make in the event of a flat tyre. Observe the "MOExtended tyres (tyres with run-flat characteristics)" section (Y page 330).

ROnly fit tyres of the correct size onto the

wheels.

RAfter fitting new tyres, run them in at mod- erate speeds for the first 100 km, as they only reach their full performance after this distance.

RDo not drive with tyres which have too little

tread depth, as this significantly reduces the traction on wet roads (aquaplaning).

RReplace the tyres after six years at the lat-

est, regardless of wear.

Observe the notes on the emergency spare wheel (Y page 365).

MOExtended tyres (tyres with run-flat characteristics) With MOExtended tyres (tyres with run-flat characteristics), you can continue to drive

your vehicle even if there is a total loss of pressure in one or more tyres. Only use MOExtended tyres in conjunction with an activated tyre pressure loss warning system or tyre pressure monitoring system and only on tyres specifically inspected by Mercedes-Benz. 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.

Notes on driving with MOExtended tyres in the event of a flat tyre can be found in the "Breakdown assistance" section (Y page 330).

Winter operation Points to remember 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 356).

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. 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.

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. These tyres have been developed specifically for driving in 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 permanent SPEEDTRONIC so that it does not exceed the maximum permissible speed for the M+S tyres(Y page 179). If you have fitted M+S tyres: X Check the tyre pressures (Y page 350). X Restart the tyre pressure loss warning sys-

tem (Y page 351).

X Restart the tyre pressure monitor

(Y page 355).

For more information on driving with the emergency spare wheel, see (Y page 365).

Winter operation 349

Snow chains G WARNING If you have fitted snow chains to the front wheels, they may scrape against the vehicle body or chassis components. This could cause damage to the vehicle or the tyres. There is a risk of an accident. To avoid hazardous situations: Rnever fit snow chains on the front wheels Rfit snow chains to the rear wheels in pairs.

! Vehicles with steel wheels: if you wish

to fit snow chains to steel wheels, make sure that you remove the respective wheels' hubcaps first. The hubcaps may otherwise be damaged.

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. If you intend to fit snow chains, please bear the following points in mind: Rsnow chains cannot be fitted to all wheel- tyre combinations. Permissible wheel-tyre combinations (Y page 361).

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 a road that is not snow-cov- ered.

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.

i You may wish to deactivate

ESP®(Y page 73) 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).

For more information on driving with the emergency spare wheel, see (Y page 365).

350 Tyre pressure

Tyre pressure Tyre pressure specifications 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.

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 an emergency spare wheel: (Y page 361). 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. The tyre pressures specified on the fuel filler flap apply to all tyres approved for this vehi- cle, if not stated otherwise.

If a tyre size precedes a tyre pressure, the following tyre pressure information is only valid for that tyre size. To test tyre pressure, use a suitable pressure gauge. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure. On vehicles fitted with the elec- tronic tyre pressure monitor, the tyre pres- sure can be checked using the on-board com- puter. 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. 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.

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 at which you are driving and the load on the tyres, the tyre temperature and thus the tyre pressure change by approximately 10 kPa per 10 † (0.1 bar/1.5 psi). Take this into account when checking the pressure of warm tyres and only correct it 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.

The values on the tyre pressure information label (fuel filler flap) for the vehicle in "parti- ally laden" and "fully laden" conditions apply when driving at maximum speed. Despite the values stated on the tyre pressure informa- tion label, for the vehicle with "partially laden up to 210 km/h" status, the values can be reduced as follows, without a reduc- tion in safety: RÒ30 kPa (Ò0.3 bar/Ò4 psi) for all models This does not apply to vehicles towing a trailer. This improves the ride comfort of your vehi- cle; however, the fuel consumption may increase slightly.

Tyre pressure 351

H Environmental note Check the tyre pressure regularly, at least every 14 days.

Tyre pressure loss warning system General notes While the vehicle is in motion, the tyre pres- sure loss warning system monitors the set tyre pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction dis- play. You can recognise the tyre pressure loss warning by the Run Flat Indicator active Restart with OK message which appears in the Service menu of the multi- function display. Information on the message display can be found in the "Restarting the tyre pressure loss warning system" section (Y page 352).

Important safety notes The tyre pressure warning system does not warn you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure (Y page 350). The tyre pressure loss warning does not replace the need to regularly check the tyre pressures. An even loss of pressure on sev- eral tyres at the same time cannot be detec- ted by the tyre pressure loss warning system. 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.

352 Tyre pressure

The function of the tyre pressure loss warning system is limited or delayed if: Rsnow chains are fitted to your vehicle's

tyres.

Rroad conditions are wintry. Ryou are driving on sand or gravel. Ryou adopt a very sporty driving style (cor- nering at high speeds or driving with high rates of acceleration).

Ryou are towing a very heavy or large trailer. Ryou are driving with a heavy load (in the

vehicle or on the roof).

Restarting the tyre pressure loss warn- ing system Restart the tyre pressure loss warning system if you have: Rchanged the tyre pressure Rchanged the wheels or tyres Rfitted new wheels or tyres X Before restarting, consult the table of tyre pressures on the inside of the fuel filler flap to ensure that the tyre pressure in all four tyres is set correctly for the respective operating conditions. The tyre pressure loss warning system can only give reliable warnings if you have set the correct tyre pressure. If an incorrect tyre pressure is set, these incorrect values will be monitored.
