Raising the vehicle G WARNING When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle. The jack is designed exclusively for jacking up the vehicle at the jacking points built into both sides of the vehicle. The jack saddle must be placed centrally under the jacking point. The jack must always be vertical when in use, especially on inclines or declines. The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for

performing maintenance work under the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Always firmly engage the parking brake and block the wheels with wheel chocks or other sizable objects before raising the vehicle with the jack. Do not disengage the parking brake while the vehicle is raised. Make sure that the ground on which the vehicle is standing and where you place the jack is solid, level and not slippery. If necessary, use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-slip underlay, for example a rubber mat. Do not use wooden blocks or similar objects as a jack underlay. Otherwise, the jack may not be able to achieve its load-bearing capacity if it is not at its full height. Never start the engine when the vehicle is raised. Also observe the notes on the jack.

X Turn the jack back to its initial position and

store it together with the rest of the tire- change tool kit in the stowage well under the trunk floor.

i When you are driving with the emergency

spare wheel mounted, the tire pressure monitoring system cannot function reliably. Only restart the tire pressure monitoring system when the defective wheel has been replaced with a new wheel. All mounted wheels must be equipped with functioning sensors and the defective wheel should no longer be in the vehicle.

MOExtended tires (tires with run-flat properties) MOExtended tires (tires with run-flat properties) allow you to continue driving your vehicle even if one or more tires are entirely deflated. MOExtended tires may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitoring system. The maximum permissible distance which can be driven in run-flat mode depends on the load in the vehicle. You can drive 50 miles (80 km) if the vehicle is partially laden and 18 miles (30 km) if it is fully laden. 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).

430 Battery

G WARNING The handling characteristics of your vehicle deteriorate in run-flat mode, for example: Rwhen cornering Rwhen braking Rwhen accelerating rapidly Adapt your driving style accordingly and avoid sudden changes in direction and sudden acceleration, as well as driving over obstacles (i.e. curbs, potholes), and driving off-road. This is particularly the case when the vehicle is heavily laden. The maximum permissible distance that can be driven in run-flat mode depends to a large extent on the loads placed on the vehicle. It can be shorter due to high speeds, a heavy load, sudden changes in direction, the road surface condition, outside temperature, etc., or further if you drive carefully and conservatively. Do not continue to drive in run-flat 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 tire. After driving in run-flat mode, you must have the wheel(s) checked for damage at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. The defective tire must be replaced in every case. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

i When replacing one or all tires, make sure

that you only use tires marked MOExtended and of the specified size for the vehicle.

Jump-starting

G WARNING Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Read all instructions before proceeding.

! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may

damage the catalytic converter22 and create a risk of fire. Do not use a rapid-charging device to start the engine. Make sure the jumper cables are not damaged. Make sure the jumper cables are not touching any other metal objects when they are connected to the battery.

If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jumper cables. Observe the following points: X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,

jump-start the vehicle using a second battery or a jump-starting device.

X Only jump-start the vehicle when the engine is cold and the catalytic converter system has

cooled down23.

X Do not start the engine if the battery is frozen. Let the battery thaw first. X Jump-starting may only be performed from batteries with a nominal voltage of 12 V. X Only use jumper cables which have a sufficient cross-section and insulated terminal clamps. X Make sure that the jumper cables cannot come into contact with parts, such as the pulley

or the fan. These parts move when the engine is started and while it is running.

X If the battery is fully discharged, leave the battery that is being used to jump-start connected

for a few minutes before attempting to start. This charges the empty battery a little.

i Jumper cables and further information about jump-starting can be obtained from any

authorized Mercedes-Benz Center, for example. X Make sure that the two vehicles do not touch. X Secure the vehicle by applying the electric parking brake. X Shift the transmission to position P.

Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 29).

Important safety notes

Consult an authorized Mercedes-Benz Center if you require information on approved and recommended tires and wheels for summer and winter operation. Advice on purchasing and caring for tires is also available there. G WARNING Replace rims or tires with the same designation, manufacturer and type as shown on the original part. For further information contact an authorized Mercedes-Benz Center. If incorrectly sized rims and tires are mounted, the wheel brakes or suspension components can be damaged. Also, the operating clearance of the wheels and the tires may no longer be correct. G WARNING Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them. When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Retreaded tires are not tested or recommended by Mercedes-Benz, since previous damage cannot always be

recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used. G WARNING If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle appears unsafe, have the vehicle towed to the nearest authorized Mercedes-Benz Center or tire dealer for repairs. G WARNING Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You might lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build- up and possibly a fire.

i Further information about Tires and

wheels can be obtained from any authorized Mercedes-Benz Center.

Operation Notes on driving RIf the vehicle is heavily laden, check the tire pressures and correct them if necessary. RWhen 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, can get damaged.

Notes on regularly inspecting wheels and tires G WARNING Regularly check the tires for damage. Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them.

RRegularly check the wheels and tires of

your vehicle for damage (e.g. cuts, punctures, tears, bulges on tires and deformation or cracks or severe corrosion on wheels) 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.

RRegularly check the tire tread depth and

the condition of the tread across the whole width of the tire (Y page 443). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.

RAll wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve (such as tire pressure monitoring systems) other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle.

RRegularly check the pressure of all the tires including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 445).

Tire tread G WARNING Although the applicable federal motor vehicle safety laws consider a tire to be worn when the tread wear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we

Operation 443

recommend that you do not allow your tires to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely.

Do not use tires that are excessively worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 inch (3 mm). Tread wear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They become visible as soon as a tread depth of approximately 1/16 inch (1.6 mm) has been reached. If this is the case, the tire is so worn that it must be replaced. The recommended tread depth for summer tires is at least 1/8 inch (3 mm). The recommended tread depth for winter tires is at least 1/6 inch (4 mm).

Bar marking : for tread wear is integrated into the tire tread.

Notes on selecting, mounting and replacing tires ROnly mount tires and wheels of the same

type and make.

ROnly mount tires of the correct size onto

the wheels.

RAfter mounting new tires, run them in at

moderate speeds for the first 60 miles

444 Winter operation

(100 km) as they only reach their full performance after this distance.

RDo not use tires that are excessively worn

as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 inch (3 mm).

RReplace the tires after six years at the

latest, regardless of wear. This also applies to the spare wheel/emergency spare wheel.

The service life of tires depends on the following factors amongst other things: Rdriving style Rtire pressure Rmileage

MOExtended tires (tires with run-flat properties) MOExtended tires (tires with run-flat properties) allow you to continue driving your vehicle even if one or more tires are entirely deflated. MOExtended tires may be used only in conjunction with the activated tire pressure loss warning system or the activated tire pressure monitoring system and only on wheels specifically tested by Mercedes-Benz. You will find notes on driving with MOExtended tires in the "Breakdown assistance" section (Y page 429).

Winter operation Please bear the following in mind At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at an authorized Mercedes- Benz Center. Observe the notes in the "Changing a wheel" section (Y page 465).

Driving with summer tires At temperatures below 45 ‡ (+7 †), the elasticity of summer tires and therefore also traction and braking capability are reduced considerably — equip your vehicle with M+S tires. Using summer tires at very cold temperatures could cause tears to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage.

M+S tires At temperatures below 45 ‡(+7 †), use winter tires or all-season 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, as these tires have been designed specifically for driving on snow. Use M+S tires of the same make and tread on all wheels to maintain safe handling characteristics. G WARNING M+S tires with a tread depth of less than 1/6
inch (4 mm) must be replaced immediately. They are no longer suitable for use in winter.

Always observe the maximum permissible speed specified for the M+S tires you have mounted. Once you have mounted the winter tires: X Check the tire pressures (Y page 449). X Restart the tire pressure monitor

(Y page 449). G WARNING If you use your spare wheel when M+S tires are mounted on the other wheels, be aware that the difference in tire characteristics

impairs cornering ability and reduces driving stability. Adapt your driving style accordingly. Have the spare wheel replaced by a normal wheel with an M+S tire at the nearest Mercedes-Benz Center.

Snow chains For safety reasons, Mercedes-Benz recommends that you only use snow chains which have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. ! You must drive at raised vehicle level if

snow chains have been mounted. The vehicle could otherwise be damaged. ! There is not enough space for snow

chains on some wheel sizes. Observe the information under "Tires and wheels" in the "Technical Data" section to avoid damage to the vehicle or the wheels.

ROnly use snow chains when driving on

roads completely covered by snow. Do not exceed the maximum permissible speed of 30 mph (50 km/h). Remove the snow chains as soon as possible when you are no longer driving on snow-covered roads.

RLocal regulations may restrict the use of snow chains. Applicable regulations must be observed if you wish to mount snow chains.

RSnow chains must not be mounted on

emergency spare wheels.

If you intend to mount snow chains, please bear the following points in mind: Ryou may not attach snow chains to all

wheel-tire combinations; see the information under "Wheel and tire combinations" in the "Wheels and tires" section.

Rmount snow chains only in pairs and only

to the rear wheels. Observe the manufacturer's installation instructions.

Tire pressure 445

! If snow chains are mounted on the front

wheels, the snow chains could grind against the bodywork or components of the chassis. This could result in damage to the vehicle or the tires.

! 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.

i You may wish to deactivate

ESP®(Y page 64) when pulling away with snow chains mounted. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action).

Tire pressure Tire pressure specifications G WARNING Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

The recommended tire pressures for the tires mounted at the factory can be found on the labels described here.

446 Tire pressure

Option 1) Tire and Loading Information placard on the B-pillar on the driver's side of the vehicle (Y page 452). The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed. i The specifications given on the following Tire and Loading Information placard are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressures applicable to your vehicle can be found on the Tire and Loading Information placard on your vehicle.

: Recommended tire pressures Option 2) Tire pressure table on the inside of the fuel filler flap. The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. i Specifications shown in the examples of

tire pressure tables are for illustration purposes only. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. Tire pressure specifications applicable to your vehicle are located in your vehicle's tire pressure table.

Example: tire pressure table for all tires approved ex-works for this vehicle 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 passengers and amounts of luggage. The actual number of seats may differ.

Example: tire pressure table with tire dimensions 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 459).

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.

Option 3) The tire pressure for the emergency/collapsible spare wheel (depending on vehicle equipment) can be found: Rprinted in yellow on the rim of the

emergency/collapsible spare wheel Rin the "Wheel and tire combinations" section (Y page 466) in this manual

Ron the Tire and Loading Information placard

on the B-pillar on the driver's side.

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 further information, consult a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Tire pressure 447

Important notes on tire pressure G WARNING Should the tire pressure drop repeatedly: Rcheck the tire for foreign bodies. Rcheck whether the wheel is losing air or the

valve is leaking.

Rmake sure that only a valve cap approved by Mercedes-Benz is used on the tire valve.

Tire pressures that are too low have a negative effect on vehicle safety, which could lead you to cause an accident.

To test tire pressure, use a suitable tire pressure gauge. 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. 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 not been driven more 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 and 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.
