When the bonnet is open, and the windscreen wipers are set in motion, you can be injured by the wiper linkage. There is a risk of injury. Always switch off the windscreen wipers and the ignition before opening the bonnet.
! Make sure that the windscreen wipers are not folded away from the windscreen. Oth- erwise, you could damage the windscreen wipers or the bonnet.
Raising the active bonnet increases the clear- ance to hard components, such as the engine. If the active bonnet has been triggered, it is raised at the rear in the area around the hinge by approximately 60 mm. For the drive to the workshop, reset the trig- gered active bonnet yourself. If the active bonnet has been triggered, pedestrian pro- tection may be limited. Resetting G WARNING Certain components in the engine compart- ment could be very hot, e.g. the engine, the radiator and parts of the exhaust system. There is a risk of injury when accessing the engine compartment. As far as possible, allow the engine to cool down and only touch the following compo- nents.
X Make sure that the windscreen wipers are
switched off.
X Pull release lever : on the bonnet.
The bonnet is released.
X With your hand flat, push down active bon-
net : in the area around the hinges on both sides (arrows) until you feel it engage. If you can raise the active bonnet slightly in the area around the hinges, it is not engaged correctly. Repeat the step. If the bonnet can then still be raised, drive directly to a qualified specialist workshop. Do not drive faster than 100 km/h.
X Reach into the gap between the bonnet and
the radiator trim and press bonnet catch lever ; to the left. X Raise the bonnet.
When checking the oil level: Rpark the vehicle on a level surface. Rthe engine should be switched off for
approximately five minutes if the engine is at normal operating temperature.
Rif the engine is not at normal operating temperature, e.g. if the engine was only started briefly: wait about 30 minutes before carrying out the measurement.

X Wipe off oil dipstick :. X Slowly slide oil dipstick : into the guide
tube to the stop, and take it out again. If the level is between MIN mark = and MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark
= or below, top up with 1.0 litre of engine oil.
Adding engine oil G WARNING If engine oil comes into contact with hot com- ponents in the engine compartment, it may ignite. There is a risk of fire and injury. Make sure that engine oil does not spill out over the filler neck. Allow the engine to cool down and thoroughly clean the components that have come into contact with engine oil before you start the engine. H Environmental note When topping up the oil, take care not to spill any. If oil enters the soil or waterways, it is harmful to the environment.
! Only use engine oils and oil filters that have been approved for vehicles with a service system. You can obtain a list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products at any Mercedes-Benz Service Centre. Damage to the engine or exhaust system is caused by the following: Rusing engine oils and oil filters that have
not been specifically approved for the service system
Rchanging the engine oil and oil filter after missing the change interval required by the service system
Rusing engine oil additives
! Do not add too much oil. Topping up with too much engine oil can result in damage
288 Engine compartment
to the engine or to the catalytic converter. Have excess engine oil siphoned off.
Checking the coolant level when the cool- ant temperature is over 40 † can lead to damage to the engine or engine cooling system.
Example: engine oil filler cap X Turn cap : anti-clockwise and remove it. X Top up the engine oil.
If the oil level is at or below the MIN mark on the oil dipstick, top up with 1.0 litre of engine oil.
X Replace cap : on the filler neck and turn
clockwise. Make sure that the cap locks securely into place.
X Check the oil level again with the oil dip-
stick (Y page 287).
For further information on engine oil, see (Y page 343).

Information about Service Resetting the ASSYST PLUS service inter- val display ! If the ASSYST PLUS service interval dis- play has been inadvertently reset, this set- ting can be corrected at a qualified special- ist workshop. Have service work carried out as described in the Service Booklet. This may otherwise lead to increased wear and damage to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a Mercedes-Benz Service Centre, will reset the ASSYST PLUS service interval display after the service work has been carried out. You can also obtain further information on main- tenance work, for example. Special service requirements The prescribed service interval is based on normal operation of the vehicle. Service work will need to be performed more often if the vehicle is operated under arduous conditions or increased loads, for example: Rregular city driving with frequent intermedi-
ate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long peri-
ods
In these or similar operating conditions, have the air filter, engine oil and oil filter, for exam- ple, changed more frequently. The tyres must
be checked more frequently if the vehicle is operated under increased loads. Further information can be obtained at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. Driving abroad An extensive Mercedes-Benz Service network is also available in other countries. The Service Hotline's current telephone numbers for use when you are abroad are to be found in the "Mercedes-Benz Service24h" section of the Service Booklet.
Care General notes H Environmental note Dispose of empty packaging and cleaning cloths in an environmentally responsible man- ner.
! For cleaning your vehicle, do not use any
of the following: Rdry, rough or hard cloths Rabrasive cleaning agents Rsolvents Rcleaning agents containing solvents Do not scrub. Do not touch the surfaces or protective films with hard objects, e.g. a ring or ice scraper. You could otherwise scratch or damage the surfaces and protective film. ! Do not park up the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Regular care of your vehicle is a condition for retaining the quality in the long term. Use care products and cleaning agents rec- ommended and approved by Mercedes-Benz.
Care of the exterior Automatic car wash G WARNING Braking efficiency is reduced after the vehicle has been washed. There is a risk of an acci- dent. After washing the vehicle, brake carefully while paying attention to the traffic conditions in order to restore full braking efficiency.
! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automati- cally in certain situations. To prevent dam- age to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in the follow- ing or other similar situations: Rwhen towing the vehicle Rin the car wash
! Make sure that the automatic transmis- sion is in position N when washing your vehicle in a tow-through car wash. The vehi- cle could be damaged if the transmission is in another position.
! Make sure that:
Rthe side windows and sliding sunroof are
closed completely.
Rthe blower for the ventilation/heating is switched off (OFF button is depressed/ airflow control is turned to position 0). Rthe windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged. You can wash the vehicle in an automatic car wash from the very start. Wash off excess dirt before cleaning the vehi- cle in an automatic car wash.
Care 291
After using an automatic car wash, wipe off wax from the windscreen and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the wind- screen.
Washing by hand In some countries, washing by hand is only allowed at wash bays that are specially designed for this purpose. Observe the legal requirements for each individual country. X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean. X Use a mild cleaning agent, such as a car shampoo approved by Mercedes-Benz.

the air inlet.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all traces of road salt deposits carefully and as soon as possible.
High-pressure cleaning equipment G WARNING The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the outside to tyres or chassis components. Com- ponents damaged in this way can unexpect- edly fail. There is a risk of an accident. Do not use high-pressure cleaners with circu- lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced immediately.
! Always maintain a distance of at least 30 cm between the vehicle and the high-
292 Care
pressure cleaner nozzle. Information about the correct distance is available from the equipment manufacturer. Move the high-pressure cleaner nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtyres Rdoor gaps, roof gaps, joints etc. Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim elements Rventilation slots Damaged seals or electrical components can lead to leaks or failures.
Cleaning the wheels ! Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.
! Do not park up the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Cleaning the paintwork ! Do not affix:
Rstickers Rfilms Rmagnetic plates or similar items to painted surfaces. You could otherwise damage the paintwork.
X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard. X Soak insect remains with insect remover and rinse off the treated areas afterwards. X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin, oils, fuels and greases by rubbing gently with a cloth soaked in petroleum ether or lighter fluid.
X Use tar remover to remove tar stains. X Use silicone remover to remove wax. The following cannot always be completely repaired: Rscratches Rcorrosive deposits Rareas affected by corrosion Rdamage caused by inadequate care In such cases, visit a qualified specialist work- shop.
Care and treatment of matt paintwork ! Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt effect: RVigorous rubbing with unsuitable mate-
rials.
RFrequent use of car washes. RWashing the vehicle in direct sunlight. ! Never use paint cleaner, buffing or pol- ishing products, or gloss preserver, e.g. wax. These products are only suitable for high-gloss surfaces. Their use on vehicles with matt finish leads to considerable sur- face damage (shiny, spotted areas). Always have paintwork repairs carried out at a qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear matt finish. This will help you to avoid damage to the paintwork due to incorrect treatment. These notes also apply to light-alloy wheels with a clear matt finish. i The vehicle should preferably be washed by hand using a soft sponge, car shampoo and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and approved Mercedes-Benz care products.

i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified spe- cialist workshop.
MOExtended tyres (tyres with run-flat characteristics) General notes With MOExtended tyres (tyres with run-flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tyres. The affected tyre must not show any clearly visible dam- age. You can recognise MOExtended tyres by the MOExtended marking which appears on the tyre wall. You will find this marking next to the tyre size designation, the load-bearing capa- city and the speed index. MOExtended tyres may only be used in con- junction with an active tyre pressure loss warning system. If the pressure loss warning message appears in the multifunction display: RObserve the instructions in the display
messages (Y page 251).
RCheck the tyre for damage. RIf driving on, observe the following notes. The maximum driving distance is approx- imately 80 km when the vehicle is partially laden and approximately 30 km when the vehicle is fully laden. In addition to the vehicle load, the driving dis- tance possible depends upon: Rspeed Rroad condition Routside temperature The driving distance possible in run-flat mode may be reduced by extreme driving condi- tions/manoeuvres, or it can be increased through a moderate style of driving.
Flat tyre 301
The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tyre pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 80 km/h. i When replacing one or all tyres, make
sure that you use only: Rthe tyre size specified for the vehicle and Rtyre(s) marked "MOExtended" If a tyre has gone flat and cannot be replaced with an MOExtended tyre, a standard tyre may be used as a temporary measure. Make sure that you use the proper size and type (summer or winter tyre).
i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you addi- tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified spe- cialist workshop.
Important safety notes G WARNING When driving in emergency mode, the driving characteristics deteriorate, e.g. when corner- ing, accelerating quickly and when braking. There is a risk of accident. Do not exceed the stated maximum speed. Avoid abrupt steering and driving manoeu- vres, and driving over obstacles (kerbs, pot- holes, off-road). This applies in particular to a laden vehicle. Stop driving in emergency 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 tyre.
After driving in emergency mode, have the wheel rims checked at a qualified specialist workshop with regard to their further use. The faulty tyre must be replaced.
TIREFIT kit Important safety notes G WARNING In the following situations, the tyre sealant is unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly: Rthere are cuts or punctures in the tyre
larger than those mentioned above.

X Press on/off switch ? on the tyre inflation
compressor to ON. The tyre inflation compressor is switched on. The tyre is inflated.
i First, tyre sealant is pumped into the tyre.
The pressure can briefly rise to approx- imately 500 kPa (5 bar/73 psi). Do not switch off the tyre inflation com- pressor during this phase.
X Let the tyre inflation compressor run for a maximum of ten minutes. The tyre should then have attained a pressure of at least 200 kPa (2.0 bar/29 psi).
! Do not operate the tyre inflation com- pressor for longer than ten minutes at a
time without a break. It may otherwise overheat. The tyre inflation compressor can be oper- ated again once it has cooled down.
If a pressure of 200 kPa (2.0 bar/29 psi) has been achieved after ten minutes, see (Y page 303). If a pressure of 200 kPa (2.0 bar/29 psi) has not been achieved after ten minutes, see (Y page 303). i If the tyre sealant leaks out, allow it to dry. It can then be removed like a layer of film. If you get tyre sealant on your clothing, have it cleaned as soon as possible with perchloroethylene.
Tyre pressure not reached If a pressure of 200 kPa (2.0 bar/29 psi) has not been achieved after ten minutes: X Switch off the tyre inflation compressor. X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again.
After a maximum of ten minutes, the tyre pressure must be at least 200 kPa (2.0 bar/ 29 psi). G WARNING If the required tyre pressure is not reached after the specified time, the tyre is too badly damaged. The tyre sealant cannot repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can significantly impair the vehicle's braking and driving char- acteristics. There is a risk of accident. Do not continue driving. Contact a qualified specialist workshop.

Battery (vehicle) Important safety notes Work on the battery, e.g. removing or instal- ling, requires specialist knowledge and the use of special tools. Therefore, always have work on the battery carried out at a qualified specialist workshop. G WARNING Work carried out incorrectly on the battery can, for example, lead to a short circuit and damage your vehicle's electronic system. This can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP® (Elec- tronic Stability Program). RIf ABS malfunctions, the wheels can lock during braking. This limits the steerability of the vehicle when braking and the braking distance may increase. There is a risk of accident.
RIf ESP® malfunctions, the vehicle will not be stabilised if it starts to skid or a wheel starts to spin. There is a risk of accident.
You should therefore have all work involving the battery carried out at a qualified specialist workshop. G WARNING Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an explosion. Before handling the battery, touch the vehicle body to remove any existing electrostatic build-up.
The highly flammable gas mixture is formed when charging the battery or jump-starting the vehicle. Always make sure that neither you nor the battery is electrostatically charged. Electro- static charge is caused, for example, by: Rwearing synthetic clothing Rthe friction of clothing on the seat Rpulling or sliding the battery over carpets
or other synthetic materials
Rrubbing the battery with a cloth G WARNING During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion. RMake sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed order of the battery terminals when connecting and disconnecting a battery. RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and dis- connecting the jump leads.
RNever connect or disconnect the battery
terminals while the engine is running. 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. H Environmental note
Batteries contain pollutants. It is illegal to dispose of them with the household rubbish. They must be collected sep- arately and disposed of in an environmentally responsible recycling system. Dispose of batteries in an environmentally responsible manner. Take discharged batteries to a qualified spe- cialist workshop or to a col- lection point for used batter- ies.
! Have the battery checked regularly at a
qualified specialist workshop. Observe the service intervals in the Service Booklet or contact a qualified specialist workshop for more information.
! Always have work on the battery carried
out at a qualified specialist workshop. Should it, in exceptional circumstances, be absolutely necessary to disconnect the bat- tery yourself, please observe the following: Rswitch off the engine and remove the
key. Check that all the indicator lamps in the instrument cluster are off. Otherwise, you may damage electronic components such as the alternator, for example.
Rfirst, disconnect the negative terminal
clamp, followed by the positive terminal clamp. Never swap the terminal clamps. The vehicle electronics may otherwise be damaged.
Ron vehicles with automatic transmission, the transmission is locked in position P after disconnecting the battery. The vehi- cle is secured against rolling away. You can then no longer move the vehicle.
306 Battery (vehicle)
The battery and the cover of the positive terminal clamp must be fitted securely dur- ing operation.
Comply with safety precautions and take pro- tective measures when handling batteries.
WARNING
Fire, naked flames and smoking are prohibited when handling the battery. Avoid creating sparks. Battery acid is caustic. Avoid con- tact with the skin, eyes or clothing. Wear suitable protective clothing, in particular gloves, an apron and a face mask. Immediately rinse acid splashes off with clean water. Consult a doc- tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
For safety reasons, Mercedes-Benz recom- mends 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 vehi- cle occupants from suffering acid burns should the battery be damaged in the event of an accident. In order for the battery to achieve the maxi- mum possible service life, it must always be sufficiently charged. Like other batteries, the vehicle battery may discharge over time if you do not use the vehicle. In such cases, have the battery dis- connected at a qualified specialist workshop.
You can also charge the battery with a charger recommended by Mercedes-Benz. For more information, please contact a quali- fied specialist workshop. Have the battery charge checked more fre- quently 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 up for a long period of time. i When you park the vehicle, remove the
key if you do not require any electrical con- sumers. The vehicle will then use very little energy, thus conserving battery power.
i If the power supply has been interrupted, e.g. if the battery was discharged, you will have to: Rset the clock (audio system/COMAND
Online, see the separate operating instructions).
Rreset the function for folding the exterior mirrors in/out automatically, by folding the mirrors out once (Y page 99).
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, naked 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 tempera- tures below freezing point. When jump-start- ing 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 maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the engine compartment (Y page 308). X Open the bonnet (Y page 285). X Connect the battery charger to the positive terminal and earth point in the same order as when connecting the donor battery in the jump-starting procedure (Y page 308).
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the discharged battery has frozen. In this case you may neither jump-start the vehicle nor charge the battery. The service life of a bat- tery that has been thawed could be reduced. The starting characteristics may be impaired, especially at low temperatures. Have the thawed battery checked at a qualified spe- cialist workshop. Only charge the installed battery with a bat- tery charger which has been tested and approved by Mercedes-Benz. 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 a Mercedes-Benz Service Centre for information and availabil- ity. Read the battery charger's operating instructions before charging the battery.
