Battery Battery Safety notes A battery should always be sufficiently charged in order to achieve its rated service life. Refer to Maintenance Booklet for battery maintenance intervals. If you use your vehicle mostly for short- distance trips, you will need to have the battery charge checked more frequently. When replacing a battery, always use a battery approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, contact an authorized Mercedes-Benz Center about steps you need to observe. G Warning! Observe all safety instructions and precautions when handling automotive batteries.

Risk of explosion.

Fire, open flames and smoking are prohibited when handling batteries. Avoid creating sparks.

378

Battery acid is caustic. Do not allow it to come into contact with skin, eyes or clothing. Wear suitable protective clothing, especially gloves, apron and faceguard. Wear eye protection. Rinse any acid spills immediately with clear water. Contact a physician if necessary. Keep children away.

Follow the instructions in this Operator’s Manual.

Batteries contain materials that can harm the environment if disposed of improperly. Large 12-volt storage batteries contain lead. Recycling of batteries is the preferred method of disposal. Many states (USA only) or provinces (Canada only) require sellers of batteries to accept old batteries for recycling.

G Warning! Failure to follow these instructions can result in severe injury or death. 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. G Warning! Do not place metal objects on the battery as this could result in a short circuit. Use leak-proof batteries only to avoid the risk of acid burns in the event of an accident.

! The battery is a Valve-Regulated Lead Acid (VRLA) battery, also referred to as “fleece” battery. 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 battery as otherwise the battery will be damaged. Even though VRLA batteries do not require topping-up of the electrolyte level and cannot be opened to check the electrolyte level, the battery condition must be checked periodically by performing a battery conductance test. Refer to Maintenance Booklet for battery condition testing 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 factory-equipped battery.

! As with any other battery, have the

battery disconnect at a qualified workshop or an authorized Mercedes-Benz Center if you do not intend to operate your vehicle for an extended period of time to prevent battery discharge. You may also connect an accessory battery charge unit expressly approved by Mercedes-Benz for your vehicle model to maintain 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 or KEYLESS-GO button is in position 1. Otherwise the alternator and other electronic components could be severely damaged. Have the battery checked regularly at an authorized Mercedes-Benz Center. Refer to Maintenance Booklet for maintenance intervals or contact an authorized Mercedes-Benz Center for further information.

i After battery power was interrupted, do

the following: RSet the clock (Y page 155).

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.

! Do not tow-start the vehicle. You could

otherwise seriously damage the automatic

transmission which is not covered by the Mercedes-Benz Limited Warranty.

! Jump starting should only be performed using the jump-start terminals located in the engine compartment. Avoid repeated and lengthy starting attempts. Do not attempt to start the engine using a battery quick-charge unit. If the engine does not run after several unsuccessful starting attempts, have it checked at the nearest authorized Mercedes-Benz Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalytic converter17 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 attached to a battery.

Rims and tires Rims and tires Notes ! 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 the ABS or the 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: RMO = Mercedes-Benz Original

equipment tires

RMOE = 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.

For information on driving with MOExtended tires, see the “Practical hints” section (Y page 373). i Vehicles with MOExtended system are not factory-equipped with a TIREFIT kit.

394

When retrofitting with tires that do not have run-flat characteristics, e.g. winter tires, you should also equip your vehicle with a TIREFIT kit. TIREFIT kits are available at any authorized Mercedes-Benz Center.

! Using tires other than those approved by

Mercedes-Benz can have detrimental effects, such as Rpoor handling characteristics Rincreased noise Rincreased fuel consumption Moreover, tires and rims not approved by Mercedes-Benz may, under load, exhibit dimensional 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 result.

i Further information on tires and rims is

available at any authorized Mercedes-Benz Center. A placard with the recommended tire inflation pressures is located on the driver’s door B-pillar. Some vehicles may have supplemental tire inflation pressure information for driving at high speeds or for vehicle loads less than the maximum

loaded vehicle condition. If such information is provided, it can be found on the placard located on the inside of the fuel filler flap. The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recommendation included with the vehicle.

For information on recommended tire inflation pressure and supplemental tire inflation pressure information for special driving situations, see (Y page 259). i The following pages also list the approved wheel rim and tire sizes for equipping your vehicles with winter tires. Winter tires are not available as standard or optional factory equipment, but can be purchased from an authorized Mercedes-Benz Center. Equipping your vehicle with winter tires approved for your vehicle model may require the purchase of two or four wheel rims of the recommended size for use with these winter tires. This depends on vehicle model and the standard or optional factory- equipped wheel rim/tire configuration on your vehicle. For more information contact an authorized Mercedes-Benz Center.

Therefore, only use approved engine oils and oil filters required for vehicles with Maintenance System. For a listing of approved engine oils and oil filters, contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only). ! Using engine oils and oil filters of

specification 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 engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty. Please follow Maintenance System recommendations for scheduled oil changes. Failure to do so will result in engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty.

Mercedes-Benz recommends MOBIL OIL.

402

Brake fluid G Warning! During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenuous operating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system’s efficiency. Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Maintenance Booklet for replacement interval. Only brake fluid approved by Mercedes-Benz is recommended. Any authorized Mercedes- Benz Center will provide you with additional information.

Premium unleaded gasoline (gasoline engine) G Warning! Gasoline is highly flammable and poisonous. It burns violently and can cause serious personal injury. Never allow sparks, flames or smoking materials near gasoline! Turn off the engine before refueling. Whenever you are around gasoline, avoid inhaling fumes and any skin or clothing contact. Extinguish all smoking materials. Direct skin contact with fuels and the inhalation of fuel vapors are damaging your health.

! To maintain the engine’s durability and performance, premium unleaded gasoline must be used. If premium unleaded gasoline is not available and low octane gasoline is used, follow these precautions: RHave the fuel tank only partially filled

with unleaded regular gasoline and fill up

Technical data

Fuels, coolants, lubricants etc. with premium unleaded gasoline as soon as possible.

RAvoid full throttle driving and abrupt

acceleration.

RDo not exceed an engine speed of

3 000 rpm if the vehicle is loaded with a light load such as two persons and no luggage.

RDo not exceed 2/3 of maximum

accelerator pedal position if the vehicle is fully loaded or operating in mountainous terrain.

Fuel requirements

Gasoline engine Only use premium unleaded gasoline. 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. Reformulated gasolines (RFG) and/or unleaded gasoline containing oxygenates such as ethanol, TAME, ETBE, IPA, IBA, and TBA can be used provided the ratio of any one

403

Technical data

Fuels, coolants, lubricants etc. 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.

Diesel engine Only use commercially available vehicular ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm SULFUR MAXIMUM). Failure to use ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL can severely damage the vehicle’s exhaust after-treatment device. To prevent malfunctions, diesel fuel with improved cold flow characteristics is offered in the winter months. Check with your fuel retailer. ! Do not fill the tank with gasoline. Do not blend diesel fuel with gasoline or kerosene. The fuel system and engine will otherwise be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

404

B5 Biodiesel Mercedes-Benz approves the use of B5
biodiesel (standard diesel with a maximum of up to 5% biodiesel content) in all Common Rail Injection (CDI) and BlueTEC diesel engines. Diesel fuels containing a higher percentage of biodiesel content will cause damage to your engine and are not approved. As biodiesel can be refined from a variety of raw materials resulting in widely varying properties, the only approved biodiesel content is one that meets ASTM D6751
specification. It must also have the necessary oxidation stability (min. 6h, proved with EN14112 method) to prevent damage to the system from deposits and/or corrosion. Please ask your service station for further information. If the B5 biodiesel blend is not sufficiently labeled to clearly indicate that it meets the above standards, please do not use it. The Mercedes-Benz Limited Warranty does not cover damage caused by the use of fuels not meeting Mercedes-Benz approved fuel standards.

Gasoline additives (gasoline engine) A major concern among engine manufacturers is carbon build-up caused by gasoline. Mercedes-Benz recommends only the use of quality gasoline containing additives that prevent the build-up of carbon deposits. 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: RWarm-up hesitation RUnstable idle RKnocking/pinging RMisfire RPower loss In areas where carbon deposits may be encountered due to lack of availability of gasoline which contains these additives, Mercedes-Benz recommends the use of additives approved by us for use on Mercedes-Benz vehicles. Contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only) for a listing of approved product(s). Follow directions on product label.

Do not blend other fuel additives with fuel. This only results in unnecessary cost and may be harmful to the engine operation. ! Damage or malfunction resulting from

poor fuel quality or from blending additional fuel additives other than those tested and approved by us for use on Mercedes-Benz vehicles are not covered by the Mercedes- Benz Limited Warranty or by any pre-owned or Extended Limited warranties.

AdBlue® AdBlue® is a non-flammable, non-toxic, colorless and odorless, water-soluble liquid. ! Only use AdBlue® complying with

ISO 22241. Do not blend with additives.

! Rinse surfaces that have come into

contact with AdBlue®, or remove AdBlue® with a moist cloth and cold water immediately. If AdBlue® has crystallized already, use cold water and a sponge. AdBlue® residues will crystallize and soil the affected surfaces.

High ambient temperatures If AdBlue® in the reservoir heats up to above 122‡ (50†) for a long period of time, for example due to direct sunlight, ammonia gas vapors may escape when opening the AdBlue® tank. G Warning! When opening the filler cap of the AdBlue® tank ammonia gas vapors may escape. Refill AdBlue® in a well ventilated area only. Ammonia gas vapors have a pungent odor and are particularly irritating for your skin, mucous membranes, and eyes. Inhaling ammonia gas vapors will cause burning eyes, nose, and throat, as well as coughing and watering eyes.

Low ambient temperatures AdBlue® freezes at a temperature of approximately 12‡ (-11†). Your vehicle is factory equipped with an AdBlue® preheating system. The vehicle can thus be operated at temperatures below 12‡ (-11†).

Technical data

Fuels, coolants, lubricants etc.

Special additives ! Only use AdBlue® complying with ISO 22241. Do not add additives to AdBlue® and do not dilute AdBlue® with water. Otherwise, the BlueTEC exhaust gas aftertreatment system could be damaged. Damage caused by using additives or diluting with water are not covered by the Mercedes-Benz Limited Warranty.

Purity The purity of AdBlue® is of particular importance for avoiding malfunctions in the exhaust gas aftertreatment. If AdBlue® is pumped out of the tank, e.g. during repair work, the same liquid must not be used to refill the tank as its purity is no longer guaranteed. ! Impurities caused for example by other

service products, cleaning agents, and dust result in increased emissions, malfunctions, catalyst damage, or engine damage.

405

Technical data

Fuels, coolants, lubricants etc. Coolants The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: RCorrosion protection RFreeze protection RBoiling protection (by increasing the boiling

point)

The cooling system was filled at the factory with a coolant providing freeze protection to approximately -35‡ (-37†) and corrosion 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 Limited Warranty.

If the antifreeze mixture is effective to -35‡ (-37†), the boiling point of the coolant in the pressurized cooling system is reached at approximately 266‡ (130†). The coolant solution must be used year round to provide the necessary corrosion protection and increase boil-over protection. Refer to the Maintenance Booklet for replacement interval. Coolant system design and coolant used determine the replacement interval. The 406

replacement interval published in the Maintenance Booklet is only applicable if MB 325.0 Anticorrosion/Antifreeze solution or other Mercedes-Benz approved products of equal specification are used to renew the coolant concentration or bring it back up to the proper level. For information on other Mercedes-Benz approved products of equal specification, contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only). To provide important corrosion protection, the solution must be at least 50% anticorrosion/antifreeze (equivalent to freeze protection to approximately -35‡ [-37†]). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protection to approximately -49‡ [-45†]), the engine temperature will increase due to the lower heat transfer capability of the solution. Therefore, do not use more than this amount of anticorrosion/antifreeze. 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 instructions.

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, contact an authorized Mercedes-Benz Center.

Anticorrosion/antifreeze Your vehicle contains a number of aluminum parts. The use of aluminum components in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically formulated to protect the aluminum parts. Failure to use such anticorrosion/antifreeze coolant will result in a significantly 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 an authorized Mercedes-Benz Center for service.
