Engine oil

Notes on oil level

Depending on your driving style, the vehicle

consumes up to 0.8 l 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.

Depending on the engine, the oil dipstick may

be installed at a different location.

When checking the oil level:

park the vehicle on a level surface.

the engine should be switched off for

approximately five minutes if the engine is

at normal operating temperature.

if 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.

Maintenance and care

Checking the oil level using the oil dip-

stick

Example:vehicles with a petrol engine

Example: vehicles with a diesel engine

Pull oil dipstick : out of the oil dipstick

tube.

Wipe off oil dipstick :.

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.

If the oil level has dropped to MIN mark

= or below, add 0.5to 1.0litre of engine

oil.

Adding engine oil

WARNING

If engine oil comes into contact with hot

engine parts, it may ignite and you could burn

yourself. Do not spill any engine oil on hot

engine parts.

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:

using engine oils and oil filters that have

not been specifically approved for the

service system

changing the engine oil and oil filter after

missing the change interval required by

the service system

using engine oil additives

Do not add too much oil. Topping up with

too much engine oil can result in damage

to the engine or to the catalytic converter.

Have excess engine oil siphoned off.

Example: engine oil filler cap

Turn cap : anti-clockwise and remove it.

Care

Notes on care

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:

dry, rough or hard cloths

abrasive cleaning agents

solvents

cleaning 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

WARNING

Braking efficiency is reduced after washing

the vehicle. This could cause an accident. For

this reason, following a car wash, drive with

particular care until the brakes are dry.

WARNING

The vehicle is braked when the HOLD function

or DISTRONIC PLUS is activated. Therefore,

deactivate the HOLD function and DISTRONIC

PLUS before the vehicle is washed in an auto-

matic 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:

the side windows and sliding sunroof are

closed completely.

the blower for the ventilation/heating is

switched off (OFF button is depressed/

airflow control is turned to position 0).

the 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.

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.

Care

267

Maintenance and care

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.

Do not use hot water and do not wash the

vehicle in direct sunlight.

Use a soft sponge to clean.

Use a mild cleaning agent, such as a car

shampoo approved by Mercedes-Benz.

Thoroughly hose downthe vehicle with a

gentle jet of water.

Do not point the water jet directly towards

the air inlet.

Use plenty of water and rinse out the

sponge frequently.

Rinse the vehicle with clean water and dry

thoroughly with a chamois.

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

WARNING

Do not use high-pressure cleaners with circu-

lar-jet nozzles (dirt grinders) to clean your

vehicle, in particular the tyres. You could oth-

erwise damage the tyres and cause an acci-

dent.

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:

tyres

door gaps, roof gaps, joints etc.

electrical components

battery

connectors

lights

seals

trim elements

ventilation 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:

stickers

films

magnetic plates or similar items

to painted surfaces. You could otherwise

damage the paintwork.

Remove impurities immediately, where

possible, whilst avoiding rubbing too hard.

Soak insect remains with insect remover

and rinse off the treated areas afterwards.

Soak bird droppings with water and rinse

off the treated areas afterwards.

Remove coolant, brake fluid, tree resin,

oils, fuels and greases by rubbing gently

with a cloth soaked in petroleum ether or

lighter fluid.

268

Care

Maintenance and care

Use tar remover to remove tar stains.

Use silicone remover to remove wax.

The following cannot always be completely

repaired:

scratches

corrosive deposits

areas affected by corrosion

damage 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:

Vigorous rubbing with unsuitable mate-

rials.

Frequent use of car washes.

Washing 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.

The vehicle should preferably be washed

by hand using a soft sponge, car shampoo

and plenty of water.

Use only insect remover and car shampoo

from the range of recommended and

approved Mercedes-Benz care products.

Cleaning the windows

WARNING

wise, you will damage the bonnet.

Do not use dry cloths, abrasive products,

solvents or cleaning agents containing sol-

vents to clean the inside of the windows.

Do not touch the insides of the windows

with hard objects, e.g. an ice scraper or

ring. There is otherwise a risk of damaging

the windows.

Cleanthe water drainage channels of the

windscreen and the rear window at regular

intervals. Deposits such as leaves, petals

and pollen may under certain circumstan-

ces prevent water from draining away.This

can lead to corrosion damage and damage
