messages (Y page 280).
RCheck the tire for damage. RIf driving on, observe the following notes. The maximum driving distance is approximately 50 miles (80 km) when the vehicle is partially laden and approximately 18 miles (30 km) when the vehicle is fully laden. In addition to the vehicle load, the driving distance possible depends upon: Rspeed Rroad condition Routside temperature The driving distance possible in run-flat mode may be reduced by extreme driving conditions/maneuvers, 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 tire pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 50 mph (80 km/h). i When replacing one or all tires, make sure
that you use only tires: Rof the size specified for the vehicle and Rmarked "MOExtended" If a tire has gone flat and cannot be replaced with a MOExtended tire, a standard tire may be used as a temporary measure. Make sure that you use the proper size and type (summer or winter tire).

HYBRID vehicles: make sure that you read the "HYBRID" supplement included in the
360 Battery (vehicle)
vehicle literature. You could otherwise fail to recognize dangers e.g. due to high voltage. For safety reasons, Mercedes-Benz recommends that you only use batteries which have been tested and approved for your vehicle by Mercedes-Benz. These batteries provide increased impact protection to prevent vehicle occupants from suffering acid burns should the battery be damaged in the event of an accident. In order for the battery to achieve the maximum possible service life, it must always be sufficiently charged. The vehicle battery, like other batteries, can discharge over time if you do not use the vehicle. In this case, have the battery disconnected at a qualified specialist workshop. You can also charge the battery with a charger recommended by Mercedes- Benz. Contact a qualified specialist workshop for further information. Have the battery condition of charge checked more frequently if you use the vehicle mainly for short trips or if you leave it standing idle for a lengthy period. Consult a qualified specialist workshop if you wish to leave your vehicle parked for a long period of time. i Remove the SmartKey if you park the vehicle and do not require any electrical consumers. The vehicle will then use very little energy, thus conserving battery power.
i If the power supply has been interrupted, e.g. if you reconnect the battery, you will have to: Rset the clock. Information on setting the
clock can be found in the separate operating instructions. On vehicles with COMAND and a navigation system, the clock is set automatically.
Rreset the function for folding the exterior mirrors in/out automatically, by folding the mirrors out once (Y page 123).
Charging the battery G WARNING During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion. Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery. G WARNING Battery acid is caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek medical attention. G WARNING A discharged battery can freeze at temperatures below freezing point. When jump-starting the vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion. Allow the frozen battery to thaw out before charging it or jump-starting.
! Only use battery chargers with a
maximum charging voltage of 14.8 V.
! Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the engine compartment (Y page 362). X Open the hood. X Connect the battery charger to the positive
terminal and ground point in the same order as when connecting the donor battery in the jump-starting procedure (Y page 362).
If, at low temperatures, the indicator lamps/ warning lamps in the instrument cluster do not light up, it is highly likely that the discharged battery has frozen. In this case, you may neither charge the battery nor jump-
start the vehicle. The service life of a thawed- out battery may be shorter. The starting characteristics may be impaired, especially at low temperatures. Have the thawed-out battery checked at a qualified specialist workshop. Never charge a battery still installed in the vehicle unless a battery charger unit approved by Mercedes-Benz is being used. A battery charger unit specially adapted for Mercedes-Benz vehicles and tested and approved by Mercedes-Benz is available as an accessory. It permits the charging of the battery in its installed position. Contact an authorized Mercedes-Benz Center for further information and availability. Read the battery charger's operating instructions before charging the battery.

Important safety notes
G WARNING If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an accident. Always replace wheels and tires with those that fulfill the specifications of the original part. When replacing wheels, make sure to use the correct: Rdesignation Rmodel When replacing tires, make sure to use the correct: Rdesignation Rmanufacturer Rmodel G WARNING A flat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident. Tires without run-flat characteristics: Rdo not drive with a flat tire. Rimmediately replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop.
Tires with run-flat characteristics: Rpay attention to the information and
warning notices on MOExtended tires (tires with run-flat characteristics).
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 workshop and ask about: Rsuitability Rlegal stipulations Rfactory recommendations Information on the dimensions and types of wheels and tires for your vehicle can be found in the "Wheel/tire combinations" section (Y page 400). Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar (Y page 383)
Ron the tire pressure label on the fuel filler
flap (Y page 176)
Runder "Tire pressure" (Y page 376)
Operation Information on driving If the vehicle is heavily loaded, check the tire pressures and correct them if necessary. While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires
and wheels checked at a qualified specialist workshop. When parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged.
Regular checking of wheels and tires G WARNING Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately.
Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as: Rcuts in the tires Rpunctures Rtears in the tires Rbulges on tires Rdeformation or severe corrosion on wheels Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 373). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface. All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems.
Operation 373
Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (Y page 376). Observe the notes on the emergency spare wheel (Y page 410). The service life of tires depends, among other things, on the following factors: Rdriving style Rtire pressure Rdistance covered
Important safety notes on the tire tread G WARNING Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. Minimum tire tread depth for: RSummer tires: â in (3 mm) RM+S tires: ã in (4 mm) For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached.
374 Winter operation
Bar indicator : for tread wear is integrated into the tire tread. Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once a tread depth of approximately á in (1.6 mm) has been reached. If this is the case, the tire is so worn that it must be replaced.
Selecting, mounting and replacing tires ROnly mount tires and wheels of the same
type and make. Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics" section (Y page 354).
ROnly mount tires of the correct size onto
the wheels.
RBreak in new tires at moderate speeds for the first 60 miles (100 km). They only reach their full performance after this distance. RDo not drive with tires which have too little
tread depth, as this significantly reduces the traction on wet roads (hydroplaning).
RReplace the tires after six years at the
latest, regardless of wear.
Observe the notes on the emergency spare wheel (Y page 410).
MOExtended tires (tires with run-flat properties) With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor and on wheels specifically tested by Mercedes-Benz.
Notes on driving with MOExtended tires with a flat tire (Y page 354). i Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit can be obtained from a qualified specialist workshop.
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 395).
Driving with summer tires At temperatures below 45 ‡ (+7 †), summer tires lose elasticity significantly, and therefore traction and braking power as well. Change the tires on your vehicle to M+S tires. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage.
M+S tires G WARNING M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter and do not provide sufficient traction. There is a risk of an accident. M+S tires with a tread depth of less than ã in (4 mm) must be replaced immediately.
At temperatures below 45 ‡ (+7 †), use winter tires or all-weather tires. Both types of tire are identified by the M+S marking.
Only winter tires bearing the i snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions. Only these tires will allow driving safety systems such as ABS and ESP® to function optimally in winter. These tires have been developed specifically for driving in snow. Use M+S tires of the same make and tread on all wheels to maintain safe handling characteristics. Always observe the maximum permissible speed specified for the M+S tires you have mounted. Once the winter tires are mounted: X Check the tire pressures (Y page 379). X Vehicles for Canada: restart the tire
pressure loss warning system (Y page 380).
X Restart the tire pressure monitor
(Y page 380).
For more information on driving with the emergency spare wheel, see (Y page 410).
Snow chains G WARNING If snow chains are installed to the front wheels, they may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires. There is a risk of an accident. To avoid hazardous situations: Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
! On vehicles with AIRMATIC, you must
drive at raised vehicle level if snow chains have been mounted. The vehicle may otherwise be damaged.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
Winter operation 375
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and wheels".
! Vehicles with steel wheels: if you wish
to mount snow chains on steel wheels, make sure that you remove the respective wheels' hubcaps first. The hubcaps may otherwise be damaged.
For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. If you intend to mount snow chains, please bear the following points in mind: RSnow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-tire combinations (Y page 400). ROnly use snow chains when driving on
roads completely covered by snow. Remove the snow chains as soon as possible when you come to a road that is not snow-covered.
RLocal regulations may restrict the use of
snow chains. Observe the appropriate regulations if you wish to mount snow chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You may wish to deactivate ESP® when pulling away with snow chains installed (Y page 73). This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action).
For more information on driving with the emergency spare wheel, see (Y page 410).
376 Tire pressure
Tire pressure Tire pressure specifications Important safety notes G WARNING Tires with tire pressures that are too low or too high are associated with the following hazards: Rthey can burst, in particular if the vehicle is
heavily laden or when driven at high speeds.
Rthe tires can wear excessively and/or
unevenly, which can severely impair tire traction.
Rthe driving, steering and braking
characteristics may be severely impaired.
There is a risk of accident. Follow recommended tire inflation pressures and check the pressure of all the tires including the spare wheel: Rmonthly, at least Rif the load changes Rbefore beginning a long journey Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
i The specifications on the sample Tire and
Loading Information placard and tire pressure tables are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications that are valid for your vehicle can be found on the Tire and Loading Information placard and tire pressure table on the vehicle.
General notes The recommended tire pressures for the tires mounted at the factory can be found on the labels described here. Operation with the emergency spare wheel (Y page 410).
Further information on tire pressures can be obtained at a qualified specialist workshop.
Tire and Loading Information placard
: Recommended tire pressures The Tire and Loading Information placard is on the B-pillar on the driver's side (Y page 383). The Tire and Loading Information placard contains the recommended tire pressures for cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed.
Tire pressure table The tire pressure table is on the inside of the fuel filler flap.
Example: tire pressure table for all tires permitted for this vehicle by the factory The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions.
Tire pressure 377
If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure. For more information, contact a qualified specialist workshop.
Important notes on tire pressure G WARNING If the tire pressure drops repeatedly, the wheel, valve or tire may be damaged. Tire pressure that is too low may result in a tire blow-out. There is a risk of an accident. RCheck the tire for foreign objects. RCheck whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, contact a qualified specialist workshop. G WARNING If you fit unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. Due to their design, retrofitted tire pressure monitors keep the tire valve open. This can also result in tire pressure loss. There is a risk of an accident. Only screw the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle onto the tire valve.
Use a suitable pressure gauge to check the tire pressure. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitoring system, the tire pressure can be checked using the on-board computer. The tire temperature and pressure increase when the vehicle is in motion. This is dependent on the driving speed and the load. Therefore, you should only correct tire pressures when the tires are cold.
Example: tire pressure table with tire dimensions If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of occupants and amounts of luggage. The actual number of seats may differ.
Some tire pressure tables show only the rim diameters instead of the full tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire sidewall (Y page 389). If the tire pressures have been set to the lower values for lighter loads and/or lower road speeds, the pressures should be reset to the higher values: Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds. i The tire pressures for increased loads
and/or higher road speeds, shown in the tire pressure table, may have a negative effect on driving comfort.
378 Tire pressure
The tires are cold: Rif the vehicle has been parked without
direct sunlight on the tires for at least three hours and
Rif the vehicle has been driven for less than
1 mile (1.6 km).
The tire temperature changes depending on the outside temperature, the vehicle speed and the tire load. If the tire temperature changes by 18 ‡ (10 †), the tire pressure changes by approximately 10 kPa (0.1 bar/ 1.5 psi). Take this into account when checking the pressure of warm tires. Only correct the tire pressure if it is too low for the current operating conditions. If you check the tire pressure when the tires are warm, the resulting value will be higher than if the tires were cold. This is normal. Do not reduce the tire pressure to the value specified for cold tires. The tire pressure would otherwise be too low. Observe the recommended tire pressures for cold tires: Ron the Tire and Loading Information placard
on the B-pillar on the driver's side
Rin the tire pressure table on the inside of
the fuel filler flap
Ron the yellow label on the emergency spare
wheel (depending on the vehicle equipment)
Underinflated or overinflated tires Underinflation G WARNING Tires with pressure that is too low can overheat and burst as a consequence. In addition, they also suffer from excessive and/ or irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too low in all the tires, including the spare wheel.
Underinflated tires may: Roverheat, leading to tire defects Rhave an adverse effect on handling
characteristics
Rwear quickly and unevenly Rhave an adverse effect on fuel consumption
Overinflation G WARNING Tires with excessively high pressure can burst because they are damaged more easily by road debris, potholes etc. In addition, they also suffer from irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too high in all the tires, including the spare wheel.
Overinflated tires may: Rincrease the braking distance Rhave an adverse effect on handling
characteristics
Rwear quickly and unevenly Rhave an adverse effect on ride comfort Rbe more susceptible to damage
Maximum tire pressures
: Example: maximum permissible tire
pressure
Never exceed the maximum permissible tire inflation pressure. Always observe the recommended tire pressure for your vehicle
when adjusting the tire pressure (Y page 376). i The actual values for tires are vehicle-
specific and may deviate from the values in the illustration.
Checking the tire pressures Important safety notes Observe the notes on tire pressure (Y page 376). Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar (Y page 383)
Ron the tire pressure label on the fuel filler
flap (Y page 176)
Rin the "Tire pressure" section Runder "Tire pressure" (Y page 376)
Checking tire pressures manually To determine and set the correct tire pressure, proceed as follows: X Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and Loading Information placard (Y page 376). X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air by pressing down the metal pin in the valve. Use the tip of a pen, for example. Then, check the tire pressure again using the tire pressure gauge.
X Screw the valve cap onto the valve. X Repeat these steps for the other tires.
Tire pressure 379
Tire pressure loss warning system (Canada only) General notes While the vehicle is in motion, the tire pressure loss warning system monitors the set tire pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tire. 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 display. You can recognize the tire pressure loss warning by the Run Flat Indicator Active Press 'OK' to Restart message which appears in the Service menu of the multifunction display. Information on the message display can be found in the "Restarting the tire pressure loss warning system" section (Y page 380).
Important safety notes The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 376). The tire pressure loss warning does not replace the need to regularly check the tire pressure. An even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system. The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire 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 maneuvers. The function of the tire pressure loss warning system is limited or delayed if: Rsnow chains are mounted on your vehicle's
tires.
Rroad conditions are wintry.
