Rbefore raising the vehicle, secure it from

rolling away by applying the parking brake and inserting wheel chocks. Never disengage 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 tires and the ground does not exceed 1.2 in (3 cm).

Rnever place your hands and 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 trunk lid

when the vehicle is raised.

Rmake sure that no persons are present in

the vehicle when the vehicle is raised.

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

chocks or other suitable items in front of the wheels of the front and rear axle.

Raising the vehicle G WARNING If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised. There is a risk of injury. Only position the jack at the appropriate jacking point of the vehicle. The base of the jack must be positioned vertically, directly under the jacking point of the vehicle.

! The jack is designed exclusively for

jacking up the vehicle at the jacking points. Otherwise, your vehicle could be damaged. 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 used incorrectly, the jack could tip over with the vehicle 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 performing maintenance work under the vehicle.

Ravoid changing the wheel on uphill and

downhill slopes.

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

360 Changing a wheel

Removing a wheel ! AMG vehicles: during removal and

repositioning of the wheel, the wheel rim can strike the ceramic-brake disc and damage it. Therefore, take precautions and get a second person to assist you. Alternatively, you can use a second alignment bolt.

! Do not place wheel bolts in sand or on a

dirty surface. The bolt and wheel hub threads could otherwise be damaged when you screw them in.

X Position jack = at jacking point ;.

Example X Make sure the foot of the jack is directly

beneath the jacking point.

X Turn crank ? clockwise until jack = sits

completely on jacking point ; and the base of the jack lies evenly on the ground.

Always pay attention to the instructions and safety notes in the "Changing a wheel" section (Y page 357). Only use wheel bolts that have been designed for the wheel and the vehicle. For safety reasons, Mercedes-Benz recommends that you only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective wheel. ! AMG vehicle with ceramic brake

discs: during removal and repositioning of the wheel, the wheel rim can strike the ceramic-brake disc and damage it. Therefore, take precautions and have a second person assist you. Alternatively, you can use a second alignment bolt.

! To prevent damage to the paintwork, hold the wheel securely against the wheel hub while screwing in the first wheel bolt.

X Unscrew the alignment bolt. X Tighten the last wheel bolt until it is finger-

tight.

X Vehicles with a collapsible spare

wheel: inflate the collapsible spare wheel (Y page 368). Only then lower the vehicle.

Lowering the vehicle G WARNING The wheels could work loose if the wheel nuts and bolts are not tightened to the specified tightening torque. There is a risk of accident. Have the tightening torque immediately checked at a qualified specialist workshop after a wheel is changed.

! Vehicles with a collapsible spare

wheel: before lowering the vehicle, inflate the collapsible spare wheel with the tire inflation compressor. The wheel rim could otherwise be damaged.

Positioning a wheel (example: vehicle with an emergency spare wheel) X Clean the wheel and wheel hub contact

surfaces.

X Slide the wheel to be mounted onto the

alignment bolt and push it on.

X Tighten the wheel bolts until they are

finger-tight.

Tightening the wheel nuts (example: vehicle with an emergency spare wheel) X Turn the crank of the jack counter-

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

X Place the jack to one side. X Tighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: to A). The specified tightening torque is 96 lb-ft(130 Nm). X Turn the jack back to its initial position.

362 Wheel and tire combinations

X Stow the jack and the rest of the vehicle

tools in the trunk again.

X Check the tire pressure of the newly

mounted wheel and adjust it if necessary. Observe the recommended tire pressure (Y page 338).

i Vehicles with tire pressure monitor: all wheels mounted must be equipped with functioning sensors.

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

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

RMO1 = Mercedes-Benz Original (only

certain AMG tires)

Mercedes-Benz Original Extended tires may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tires, wheels or accessories tested and approved by Mercedes-Benz. Certain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely affected. In addition, when driving with a load, tire dimension variations could cause the tires to come into contact with the bodywork and axle components. This could result in damage to the tires or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tires, wheels or accessories other than those tested and approved.

Information on tires, wheels and approved combinations can be obtained from any qualified specialist workshop.

Overview of abbreviations used in the following tire tables: RBA: both axles RFA: front axle RRA: rear axle The recommended pressures for various operating conditions can be found: Ron the Tire and Loading Information placard

with the recommended tire pressures on the B-pillar on the driver's side

Rin the tire pressure table on the inside of

the fuel filler flap

Observe the notes on recommended tire pressures under various operating conditions (Y page 338). Check tire pressures regularly, and only when the tires are cold. Comply with the maintenance recommendations of the tire manufacturer in the vehicle document wallet. Notes on the vehicle equipment – always equip the vehicle with: Rtires of the same size on a given axle (left/

right)

Rthe same type of tires at a given time

(summer tires, winter tires, MOExtended tires)

Vehicles 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 may be obtained from a qualified specialist workshop. i Not all wheel and tire combinations are available at the factory for all countries.

i On the following pages, you can find

information on approved wheel rims and tire sizes for equipping your vehicle with winter tires. Winter tires are not available

Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside temperatures. The table shows you which SAE classifications are to be used. The low- temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification.

Brake fluid G WARNING The brake fluid constantly absorbs moisture from the air. This lowers the boiling point of the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard. This would impair braking efficiency. There is a risk of an accident. You should have the brake fluid renewed at the specified intervals.

Comply with the important safety notes for service products when handling brake fluid (Y page 373). The brake fluid change intervals can be found in the Maintenance Booklet.

Only use brake fluid approved by Mercedes- Benz according to MB Approval 331.0. Information about approved brake fluid can be obtained at any qualified specialist workshop or on the Internet at http://bevo.mercedes-benz.com. i Have the brake fluid regularly replaced at

a qualified specialist workshop and the replacement confirmed in the Maintenance Booklet.

Coolant Important safety notes G WARNING If antifreeze comes into contact with hot components in the engine compartment, it may ignite. There is a risk of fire and injury. Let the engine cool down before you add antifreeze. Make sure that antifreeze is not spilled next to the filler neck. Thoroughly clean the antifreeze from components before starting the engine.

! Only add coolant that has been premixed with the desired antifreeze protection. You could otherwise damage the engine. Further information on coolants can be found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop. ! Always use a suitable coolant mixture,

even in countries where high temperatures prevail. Otherwise, the engine cooling system is not sufficiently protected from corrosion and overheating.

Comply with the important safety precautions for service products when handling coolant (Y page 373).

The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Rcorrosion protection Rantifreeze protection Rraising the boiling point If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant during operation is approximately 266 ‡ (130 †). The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine

cooling system against freezing down to approximately -35 ‡ (-37 †).

Rnot exceed 55% (antifreeze protection

down to -49 ‡ [-45 †]). Otherwise, heat will not be dissipated as effectively.

If the vehicle has lost coolant, add equal amounts of water and antifreeze/corrosion inhibitor. Mercedes-Benz recommends an antifreeze/ corrosion inhibitor concentrate in accordance with MB Specifications for Service Products 310.1. The coolant is checked with every maintenance interval at a qualified specialist workshop. i When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection.

Windshield washer system and headlamp cleaning system Important safety notes G WARNING Windshield washer concentrate is highly flammable. If it comes into contact with hot engine components or the exhaust system it could ignite. There is a risk of fire and injury. Make sure that no windshield washer concentrate is spilled next to the filler neck.

! Only use washer fluid that is suitable for plastic lamp lenses, e.g. MB SummerFit or MB WinterFit. Unsuitable washer fluid could damage the plastic lenses of the headlamps.

! Do not add distilled or de-ionized water to the washer fluid container. Otherwise, the level sensor may be damaged.

! Only MB SummerFit and MB WinterFit

washer fluid should be mixed together. The spray nozzles may otherwise become blocked.

Comply with the important safety notes for service products when handling washer fluid (Y page 373). At temperatures above freezing: X Fill the washer fluid reservoir with a mixture of water and windshield washer fluid, e.g. MB SummerFit.

Add 1 part MB SummerFit to 100 parts water.

At temperatures below freezing: X Fill the washer fluid reservoir with a mixture

of water and washer fluid, e.g. MB WinterFit.
