Engine oil Notes on oil level Depending on your driving style, the vehicle consumes up to 0.8 litres of oil per 1,000 km. The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds.
Checking the oil level using the oil dip- stick
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.
Rthe engine should be switched off for at least 30 minutes if the engine is not at operating temperature, e.g. if you only start the engine briefly.
X Pull dipstick : out of the dipstick tube. X Wipe off dipstick :. X Slowly slide 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 Top up the oil if necessary.
Checking the oil level using the instru- ment cluster
X Turn the key to position 2 in the ignition
lock.
X Wait approximately ten seconds until the
2 and X symbols light up in the instrument cluster display.

Information about Service 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.

148 Care
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. 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.
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- 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, 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.
Scratches, corrosive deposits, areas affected by corrosion and damage caused by inade- quate care cannot always be completely repaired. In such cases, visit a qualified spe- cialist workshop. 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.
Care and treatment of matt paintwork ! Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! 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.
If your vehicle has a clear matt finish, observe the following instructions in order to avoid damage to the paintwork due to incorrect care. 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.

lowing: Ron trailer ball couplings: the ball Ron hook-type trailer tow hitches: the inside of the hook and the moving parts X Check that the vehicle's trailer tow hitch is
working properly.
i Maintenance of the ball coupling, hook
and trailer tow hitch can also be performed at a qualified specialist workshop.
Interior care Cleaning the display ! For cleaning, do not use any of the fol-
lowing: Ralcohol-based thinner or petrol Rabrasive cleaning agents Rcommercially-available household clean-
ing agents
These may damage the display surface. Do not put pressure on the display surface when cleaning. This could lead to irrepara- ble damage to the display.
X Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer- cially available microfibre cloth and TFT/ LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth.
Cleaning the plastic trim G WARNING When cleaning the steering wheel boss and dashboard, do not use cockpit sprays or cleaning agents containing solvents. Cleaning agents containing solvents cause the surface to become porous, and as a result plastic parts may break away and be thrown around the interior when an airbag is deployed, which may result in severe injuries.
! Do not affix the following to plastic surfa-
ces: Rstickers Rfilms Rscented oil bottles or similar items You could otherwise damage the plastic.
Care 151
Seat covers from other materials ! Observe the following when cleaning:
RClean artificial leather covers with a cloth
moistened with a solution containing 1% detergent (e.g. washing-up liquid). RClean cloth covers with a microfibre
cloth moistened with a solution contain- ing 1% detergent (e.g. washing-up liquid). Rub carefully, and always wipe entire seat sections to avoid leaving visible lines. Leave the seat to dry afterwards. Cleaning results depend on the type of dirt and how long it has been there.
RClean Alcantara® covers with a damp cloth. Make sure that you wipe entire seat sections to avoid leaving visible lines.
Cleaning the seat belts ! Do not clean the seat belts using chemical cleaning agents. Do not dry the seat belts at temperatures above 80 † or in direct sunlight.
X Use clean, lukewarm water and soap solu-
tion.
! Do not allow cosmetics, insect repellent or sunscreen to come in contact with the plastic trim. This maintains the high-quality look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use car care and cleaning products recommended and approved by Mercedes-Benz. The surface may change colour tempora- rily. Wait until the surface is dry again.
Cleaning the seat covers General notes ! Do not use microfibre cloths to clean gen- uine leather, artificial leather or DINAMICA covers. If used often, these can damage the cover.
i Note that regular care is essential to
make sure that the appearance and com- fort of the covers are retained over time.
Genuine leather seat covers ! To retain the natural appearance of the
leather, observe the following cleaning instructions: RClean genuine leather covers carefully
with a damp cloth and then wipe the cov- ers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become rough and cracked.
ROnly use leather care agents that have been tested and approved by Mercedes- Benz. You can obtain these from a quali- fied specialist workshop. Leather is a natural product.

Therefore, always have work on the battery carried out at a qualified specialist workshop. If ABS is malfunctioning, the wheels could lock when braking. This limits the steerability of the vehicle when braking and may increase the braking distance. 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 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. 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.
! 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. The battery and the cover of the positive terminal clamp must be fitted securely dur- ing operation.
! Have the batteries checked and, if neces-
sary, replaced at a qualified specialist workshop every two years or at least every 20,000 km.
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.
In order for the batteries to achieve the max- imum possible service life, they must always be sufficiently charged. 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 contact with the skin, eyes or clothing. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
The vehicle battery, like other batteries, can 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. The highly flammable gas mixture is created during the charging process and when jump- starting. 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. Have the batteries' 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. Disconnect the batteries from the on-board electrical system using the battery main switch (Y page 87) if you leave it standing idle. 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.
Mercedes-Benz recommends that you do not carry out work on batteries yourself, e.g. removing or charging. Have this work per- formed at a qualified specialist workshop.
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 installed battery with a battery charger which has been tested and approved by Mercedes-Benz. These battery chargers allow the battery to be charged while still installed in the vehicle.
A battery charger unit specially adapted for Mercedes-Benz vehicles and tested and approved by Mercedes-Benz is available as an accessory.

Jump-starting
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.
! Avoid repeated and lengthy starting
attempts. Only use the jump-starting pro- cedure for the battery in the engine com- partment. Do not use a rapid-charging device to start the engine.
If starting the engine with the emergency start facility is no longer possible, a jump- start can be achieved by attaching the jump leads to the jump-starting terminals. Jump-starting is also possible from: Ranother vehicle Ran external battery If the vehicle is equipped with a jump-starting socket, it is also possible for another vehicle with a jump-starting socket and a special jump lead to jump-start your vehicle. Observe the following points: X You may only jump-start the vehicle when the engine and catalytic converter are cold. X Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
X 12 V on-board electrical system: jump- starting may only be performed from bat- teries with a nominal voltage of 12 V.
X 24 V on-board electrical system: jump- starting may only be performed from bat- teries with a nominal voltage of 24 V.
X Only use jump leads that have a sufficient
cross-section and insulated terminal clamps.
X Make sure that the jump leads 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 Jump-starting cables and further informa-
tion regarding jump starting can be obtained at any qualified specialist work- shop.
X Make sure that the two vehicles do not
touch.
X Apply the parking brake. X Move the selector lever to P. X Switch off all electrical consumers (e.g.
radio, blower, etc.).
