Warning!

The dimensions of the spare wheel (Minispare or collapsible tire) are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a spare wheel mounted. Adapt your driving style accordingly.

The spare wheel is for temporary use only. When driving with spare wheel mounted, ensure proper tire pressure and do not ex- ceed a vehicle speed of 50 mph (80 km/h).

Drive to the nearest Mercedes-Benz Center as soon as possible to have the spare wheel replaced with a regular road wheel.

Never operate the vehicle with more than one spare wheel mounted. Do not switch off the ESP® when a Minis- pare or collapsible tire is mounted.

왘 Park the vehicle in a safe distance from

moving traffic on a hard, flat surface when possible.

왘 Turn on the hazard warning flashers. 왘 Turn the steering wheel so that the front wheels are in a straight ahead position.

왘 Set the parking brake. 왘 Move the gear selector lever to P. 왘 Turn off the engine (컄 page 60). 왘 Have any passenger exit the vehicle at

a safe distance from the roadway.

i Open door only when conditions are safe to do so.

Warning!

Follow recommend inflation pressures.

Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes, etc.

Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.

왘 Detach the electric air pump. 왘 Stow electrical plug 3 and air hose 4 behind flap 1 and place the air pump back in the trunk.

i Vehicles with Advanced TPMS*: Do not activate the tire inflation pressure moni- tor (컄 page 309) until a full size wheel/tire with functioning sensor has been placed back into service on the vehicle.

418

Warning!

Have the tightening torque checked after changing a wheel. The wheels could come loose if they are not tightened to a torque of 96 lb-ft (130 Nm).

왘 Before storing the jack in the trunk, it

should be fully collapsed.

i Wrap the damaged wheel in the protective film that comes with the spare wheel and put the wheel in the trunk. You can also place the damaged wheel down into the spare wheel well. In this case, you must stow the luggage bowl in the trunk.

Lowering the vehicle 왘 Lower vehicle by turning crank coun-

terclockwise until vehicle is resting ful- ly on its own weight.

왘 Remove the jack.

1 - 5 Wheel bolts 왘 Tighten the five wheel bolts evenly, fol- lowing the diagonal sequence illustrat- ed (1 to 5), until all bolts are tight. Observe a tightening torque of 96 lb-ft (130 Nm).

MOExtended system*

The MOExtended system allows you to continue driving your vehicle even if there is a total loss of pressure in one or more tires. You may only use the MOExtended system in conjunction with Tire Pressure Monitor- ing System (U.S. vehicles), Run Flat Indica- tor (Canada vehicles), or Advanced Tire Pressure Monitoring System* (Canada only).

! The maximum distance in emergency mode depends on the vehicle’s load. It is 30 miles (50 km) if the vehicle is partially loaded and 18 miles (30 km) if the vehicle is fully loaded. The point at which the maximum driving distance begins in emergency mode is when the warning message appears in the multifunction display indicating that there is a loss of tire inflation pressure. Do not exceed the maximum speed of 50 mph (80 km/h).

Warning!

In emergency mode, your vehicle’s driving characteristics are diminished in such situa- tions as: 앫 driving around curves 앫 while braking 앫 while accelerating rapidly Therefore, your driving style must be adapt- ed accordingly. Avoid abrupt steering and driving maneuvers, as well as driving over obstacles (road curbs, potholes, or off-road areas). This is especially important if the vehicle is heavily loaded.

The emergency driving distance that can be achieved greatly depends on the demands placed on the vehicle. Depending on speed, load, driving maneuvers, road conditions, outside temperature, etc., the distance can be significantly shorter or, if the vehicle is driven cautiously, somewhat longer.

Practical hints Flat tire

Do not continue driving in emergency mode if 앫 you notice knocking sounds 앫 the vehicle starts to shake 앫 smoke develops and you smell rubber 앫 ESP® is intervening continuously 앫 you notice tears on the tire sidewalls After driving in emergency mode, you must have the rims inspected by an authorized Mercedes-Benz Center to check if they are suitable for further use. The failed tire must be replaced in any case.

i When replacing individual or all tires on the vehicle, make sure only matching tires marked with “MOExtended” are mounted in the size specified for your vehicle (컄 page 444).

Warning!

Do not place metal objects on the battery as this could result in a short circuit.

Use leak-proof battery only to avoid the risk of acid burns in the event of an accident.

420

Warning!

Failure to follow these instructions can result in severe injury or death.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 291). Never lean over batteries while connecting, 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.

! The battery is a Valve-Regulated Lead Acid (VRLA) battery, also referred to as “fleece” bat- tery. Such batteries do not require topping-up of the electrolyte level. VRLA batteries therefore do not have cell caps and the battery cover is non-removable. Do not attempt to open the bat- tery as otherwise the battery will be damaged. Even though VRLA batteries do not require top- ping-up of the electrolyte level and cannot be opened to check the electrolyte level, the bat- tery condition must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for battery condition test- ing intervals. The factory-equipped VRLA battery is leak-proofed. Only use a battery as replacement that has the same security features and is of identical size, voltage, and capacity as the facto- ry-equipped battery.

Practical hints Battery

! As with any other battery, disconnect the battery if you do not intend to operate your vehi- cle for an extended period of time to prevent bat- tery discharge or connect an accessory battery charge unit expressly approved by Mercedes-Benz for your vehicle model to main- tain the battery charge. Contact an authorized Mercedes-Benz Center for further information. The battery, the battery ventilation hose and the lateral plug must always be securely installed when the vehicle is in operation.

! Never loosen or detach battery terminal clamps while the engine is running or the SmartKey is in the starter switch.

Practical hints Jump starting

왔 Jump starting

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 very 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.

! Do not tow-start the vehicle. ! Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a bat- tery quick charge unit. If the engine does not run after several unsuc- cessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalyt- ic converter and may present a fire risk. Make sure the jumper cables do not have loose or missing insulation. Make sure the cable clamps do not touch any other metal part while the other end is still at- tached to a battery.

If the battery is discharged, the engine can be started with jumper cables and the bat- tery of another vehicle. Observe the follow- ing: 앫 Jump starting should only be performed when the engine and catalytic convert- er are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first.

앫 Only jump start from batteries with the same voltage rating (12 V). Jump start- ing with a higher voltage battery could damage the vehicle’s electrical system, which will not be covered by the Mercedes-Benz Limited Warranty.

앫 Use only jumper cables with sufficient

cross-section and insulated terminal clamps.

앫 Always make sure the jumper cables

are not on or near pulleys, fans or other parts that move when the engine is started or running.

Practical hints Towing the vehicle

왔 Towing the vehicle Mercedes-Benz recommends that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. This method is preferable to other types of towing.

! Do not tow-start the vehicle. ! Use flatbed or wheel lift/dolly equipment with SmartKey in starter switch turned to position 0. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. To prevent damage during transport, do not tie down vehicle by its chassis or suspension parts. Switch off the automatic central (컄 page 163) locking.

When circumstances do not permit the recommended towing methods, the vehicle may be towed with all wheels on the ground or front wheels raised only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be employed.

Warning!

Warning!

If circumstances require towing the vehicle with all wheels on the ground, always tow with a tow bar if: 앫 the engine will not run 앫 there is a malfunction in the brake sys-

tem

앫 there is a malfunction in the power sup- ply or in the vehicle’s electrical system This is necessary to adequately control the towed vehicle.

Prior to towing the vehicle with all wheels on the ground, make certain that the SmartKey is in starter switch position 2.

If the SmartKey is left in the starter switch position 0 for an extended period of time, it can no longer be turned in the switch. In this case, the steering is locked. To unlock, remove SmartKey from starter switch and reinsert.

With the engine not running, there is no power assistance for the steering system. In this case, it is important to keep in mind that a considerably higher degree of effort is nec- essary to steer the vehicle. Adapt your driv- ing accordingly.

! If the vehicle is towed with the front axle raised, the gear selector lever must be in position N and the engine must be shut off (SmartKey in starter switch position 0 or 1). Active braking action through the ESP® may otherwise seriously damage the brake system. When towing the vehicle with all wheels on the ground, the selector lever must be in position N and the SmartKey must be in starter switch position 2. When towing the vehicle with all wheels on the ground or the front axle raised, the vehicle may be towed only for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h).

425

Practical hints Towing the vehicle

! Towing of the vehicle should only be done using the properly installed towing eye bolt. Nev- er attach tow cable, tow rope or tow rod to the vehicle chassis, frame or suspension parts.

i When towing the vehicle with all wheels on the ground, please note the following: With the automatic central locking activated and the SmartKey in starter switch position 2, or KEYLESS-GO* start/stop button in position 2, the vehicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approximately 9 mph (15 km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking (컄 page 116).

i To signal turns while being towed with the hazard warning flasher in use, turn SmartKey in starter switch to position 2 and activate the combination switch for the left or right turn signal in the usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the hazard warn- ing flasher will operate again.

i The selector lever will remain locked in park position P and the SmartKey will not turn in the starter switch if the battery is disconnected or discharged. For more information see “Battery” (컄 page 420) or “Jump starting” (컄 page 423). For information on manual unlocking of the gear selector lever, see (컄 page 400).

Technical data Rims and tires

! Only use tires which have been tested and approved by Mercedes-Benz. Tires approved by Mercedes-Benz are developed to provide best possible performance in conjunction with the driving safety systems on your vehicle such as ABS or ESP®. Tires specially developed for your vehicle and tested and approved by Mercedes-Benz can be identified by finding the following on the tire’s sidewall: 앫 MO = Mercedes-Benz Original equipment

tires

앫 MOE = Mercedes-Benz Original Extended (tires with limited run-flat characteristics) original equipment tires

Using tires other than those approved by Mercedes-Benz may result in damage that is not covered by the Mercedes-Benz Limited Warranty.

i For information on driving with MOExtended tires, see “MOExtended system*” (컄 page 313).

438

The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recommendation included with vehicle. i The following pages also list the approved wheel rim and tire sizes for equipping your vehi- cles with winter tires. Winter tires are not avail- able as standard or optional factory equipment, but can be purchased from an authorized Mercedes-Benz Center. Depending on vehicle model and the standard or optional factory-equipped wheel rim/tire config- uration on your vehicle (Appearance Package, AMG Sport Package etc.), equipping your vehicle with winter tires approved for your vehicle model may also require the purchase of two or four wheel rims of the recommended size for use with these winter tires. See an authorized Mercedes-Benz Center for more information.

! Using tires other than those approved by Mercedes-Benz can have detrimental effects, such as 앫 poor handling characteristics 앫 increased noise 앫 increased fuel consumption Moreover, tires and rims not approved by Mercedes-Benz may, under load, exhibit dimen- sional variations and different tire deformation characteristics that could cause them to come into contact with the vehicle body or axle parts. Damage to the tires or the vehicle may be the re- sult.

i Further information on tires and rims is available at any authorized Mercedes-Benz Center. A placard with the recommended tire in- flation pressures is located on the driver’s door B-pillar. Some vehicles may have supplemental tire inflation pressure information for driving at high speeds (컄 page 302) or for vehicle loads less than the maximum loaded vehicle condition (컄 page 302). If such information is provided, it can be found on the placard located on the in- side of the fuel filler flap.

Engine oils

Engine oils are specifically tested for their suitability in our engines and durability for our service intervals. Therefore, only use approved engine oils and oil filters re- quired for vehicles with Maintenance Sys- tem. For a listing of approved engine oils and oil filters, refer to the Factory Ap- proved Service Products pamphlet (USA only), or contact an authorized Mercedes-Benz Center.

! Using engine oils and oil filters of specifica- tion other than those expressly required for the Maintenance System, or changing of oil and oil filter at change intervals longer than those called for by the Maintenance System will result in en- gine or emission control system damage not cov- ered by the Mercedes-Benz Limited Warranty.

450

Please follow Maintenance System recommen- dations for scheduled oil changes. Failure to do so could result in engine or emission control sys- tem damage not covered by the Mercedes-Benz Limited Warranty.

Brake fluid

Warning!

Engine oil additives

! Do not blend oil additives with engine oil. They may damage the engine. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.

Air conditioning refrigerant

R-134a (HFC) refrigerant and special PAG lubricating oil are used in the air condition- ing system.

! Never use R-12 (CFC) or mineral-based lu- bricating oil. Otherwise damage to the system will occur.

During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenuous op- erating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system’s efficien- cy.

Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Mainte- nance Booklet for replacement interval.

Only brake fluid approved by Mercedes-Benz is recommended. Any authorized Mercedes-Benz Center will pro- vide you with additional information.

Premium unleaded gasoline

Warning!

Gasoline is highly flammable and poisonous. It burns violently and can cause serious per- sonal injury.

Never allow sparks, flame or smoking mate- rials near gasoline!

Turn off the engine before refueling.

Whenever you are around gasoline, avoid in- haling fumes and skin or clothing contact, extinguish all smoking materials.

Direct skin contact with fuels and the inha- lation of fuel vapors can damage your health.

! To maintain the engine’s durability and per- formance, premium unleaded gasoline must be used. If premium unleaded gasoline is not avail- able and low octane fuel is used, follow these precautions: 앫 Have the fuel tank only partially filled with unleaded regular gasoline and fill up with premium unleaded gasoline as soon as pos- sible.

앫 Avoid full throttle driving and abrupt acceler-

ation.

앫 Do not exceed an engine speed of 3000 rpm if the vehicle is loaded with a light load such as two persons and no luggage.

앫 Do not exceed 2/3 of maximum accelerator pedal position if the vehicle is fully loaded or operating in mountainous terrain.

Technical data Fuels, coolants, lubricants etc.

Fuel requirements

Only use premium unleaded fuel: 앫 The octane number (posted at the

pump) must be 91 min. It is an average of both the Research Octane Number (RON) and the Motor Octane Number (MON): (RON+MON)/2. This is also known as the ANTI-KNOCK INDEX.

Unleaded gasoline containing oxygenates such as ethanol, IPA, IBA and TBA can be used provided the ratio of any one of these oxygenates to gasoline does not exceed 10%; MTBE must not exceed 15%. The ratio of methanol to gasoline must not exceed 3% plus additional cosolvents. Using mixtures of ethanol and methanol is not allowed. Gasohol, which contains 10% ethanol and 90% unleaded gasoline, can be used. These blends must also meet all other fuel requirements, such as resistance to spark knock, boiling range, vapor pressure, etc.

451

Technical data Fuels, coolants, lubricants etc.

Gasoline additives

A major concern among engine manufac- turers is carbon build-up caused by gaso- line. Mercedes-Benz recommends only the use of quality gasoline containing additives that prevent the build-up of carbon depos- its. After an extended period of using fuels without such additives, carbon deposits can build up especially on the intake valves and in the combustion area, leading to engine performance problems such as: 앫 Warm-up hesitation 앫 Unstable idle 앫 Knocking/pinging 앫 Misfire 앫 Power loss

452

In areas where carbon deposits may be encountered due to lack of availability of gasolines which contain these additives, Mercedes-Benz recommends the use of additives approved by us for use on Mercedes-Benz vehicles. Refer to Factory Approved Service Products pamphlet (USA only) or contact an authorized Mercedes-Benz Center for a listing of ap- proved product(s). Follow directions on product label. Do not blend other fuel additives with fuel. This only results in unnecessary costs and may be harmful to the engine operation.

! Damage or malfunction resulting from poor fuel quality or from blending additional fuel addi- tives other than those tested and approved by us for use on Mercedes-Benz vehicles listed in the Factory Approved Service Products pamphlet are not covered by the Mercedes-Benz Limited Warranty.

Coolants

The engine coolant is a mixture of water and anticorrosion/antifreeze, which pro- vides: 앫 Corrosion protection 앫 Freeze protection 앫 Boiling protection (by increasing the

boiling point)

The cooling system was filled at the factory with a coolant providing freeze protection to approximately -35°F (-37°C) and corro- sion protection.

! Add premixed coolant solution only. Adding water and MB 325.0 Anticorrosion/Antifreeze separately from each other, could cause engine damage not covered by the Mercedes-Benz Lim- ited Warranty.

If the antifreeze mixture is effective to -35°F (-37°C), the boiling point of the cool- ant in the pressurized cooling system is reached at approximately 266°F (130°C). The coolant solution must be used year round to provide the necessary corrosion protection and increase boil-over protec- tion. Refer to Maintenance Booklet for re- placement interval. Coolant system design and coolant used determine the replacement interval. The replacement interval published in the Maintenance Booklet is only applicable if MB 325.0 Anticorrosion/Antifreeze solu- tion or other Mercedes-Benz approved products of equal specification (see Factory Approved Service Products pam- phlet) are used to renew the coolant con- centration or bring it back up to the proper level.

For information on other Mercedes-Benz approved products of equal specification, refer to the Factory Approved Service Products pamphlet (USA only) or contact an authorized Mercedes-Benz Center. To provide important corrosion protection, the solution must be at least 50% anticor- rosion/antifreeze (equivalent to freeze protection to approximately -35°F [-37°C]). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protection to approximately -49°F [-45°C]), the engine temperature will in- crease due to the lower heat transfer capa- bility of the solution. Therefore, do not use more than this amount of anticorro- sion/antifreeze.

Technical data Fuels, coolants, lubricants etc.

If the coolant level is low, water and MB 325.0 Anticorrosion/Antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). Please make sure the mixture is in accordance with label instruc- tions. The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If you are not sure about the water quality, con- sult an authorized Mercedes-Benz Center.

453

Technical data Fuels, coolants, lubricants etc.

Anticorrosion/antifreeze Your vehicle contains a number of alumi- num parts. The use of aluminum compo- nents in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifical- ly formulated to protect the aluminum

Anticorrosion/antifreeze quantity

parts. Failure to use such anticorro- sion/antifreeze coolant will result in a sig- nificantly shortened service life. Therefore, the following product is strongly recommended for use in your vehicle: MB 325.0 Anticorrosion/Antifreeze agent.

Before the start of the winter season (or once a year in hot southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is also regularly checked each time you bring your vehicle to your authorized Mercedes-Benz Center for service.
