Engine compartment

Hood

Important safety notes

WARNING

If the hood is unlatched, it may open up when

the vehicle is in motion and block your view.

There is a risk of an accident.

Never unlatch the hood while driving.

WARNING

When opening and closing the hood, it may

suddenly fall into the closed position. There is

a risk of injury to persons within range of

movement of the hood.

Open and close the hood only when no one is

within its range of movement.

WARNING

Opening the hood when the engine is over-

heated or when there is a fire in the engine

compartment could expose you to hot gases

or other service products. There is a risk of

injury.

Let an overheated engine cool down before

opening the hood. If there is a fire in the

engine compartment, keep the hood closed

and contact the fire department.

WARNING

The engine compartment contains moving

components. Certain components, such as

the radiator fan, may continue to run or start

again suddenly when the ignition is off. There

is a risk of injury.

If you need to do any work inside the engine

compartment:

switch off the ignition

never reach into the area where there is a

risk of danger from moving components,

such as the fan rotation area

remove jewelry and watches

keep items of clothing and hair, for exam-

ple, away from moving parts

WARNING

The ignition system and the fuel injection sys-

tem work under high voltage. If you touch

components which are under voltage, you

could get an electric shock. There is a risk of

injury.

Never touch components of the ignition sys-

tem or fuel injection system when the ignition

is switched on.

Opening the hood

WARNING

Certain components in the engine compart-

ment, such as the engine, radiator and parts

of the exhaust system, can become very hot.

Working in the engine compartment poses a

risk of injury.

Where possible, let the engine cool down and

touch only the components described in the

following.

WARNING

When the hood is open and the windshield

wipers are set in motion, you can be injured by

the wiper linkage. There is a risk of injury.

Always switch off the windshield wipers and

the ignition before opening the hood.

Engine oil

General notes

Depending on your driving style, the vehicle

consumes up to 0.9 US qt (0.8 liters) of oil per

600 miles (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 in 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

WARNING

Certain components in the engine compart-

ment, such as the engine, radiator and parts

of the exhaust system, can become very hot.

Working in the engine compartment poses a

risk of injury.

Where possible, let the engine cool down and

touch only the components described in the

following.

Example

Pull oil dipstick : out of the dipstick guide

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 1.1 US qt (1.0 liter) of engine

oil.

Adding engine oil

WARNING

Certain components in the engine compart-

ment, such as the engine, radiator and parts

of the exhaust system, can become very hot.

Working in the engine compartment poses a

risk of injury.

Where possible, let the engine cool down and

touch only the components described in the

following.

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 is not spilled next to

the filler neck. Let the engine cool down and

thoroughly clean the engine oil off the com-

ponents before starting the engine.

Environmental note

When adding 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 ser-

vice 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

center.

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

replacing engine oil and oil filters after

the interval for replacement specified by

the service system has been exceeded

using engine oil additives.

Do not add too much oil. adding too much

engine oil can result in damage to the

engine or to the catalytic converter. Have

excess engine oil siphoned off.

Maintenance and care

Example: engine oil cap

Turn cap : counter-clockwise and remove

it.

Add engine oil.

If the oil level is at or below the MIN mark on

the oil dipstick, add 1.1 US qt (1.0 l) of

engine oil.

Replace cap : on the filler neck and turn

clockwise.

Ensure that the cap locks into place

securely.

Check the oil level again with the oil dip-

Checking and adding other service

products

Checking coolant level

WARNING

The engine cooling system is pressurized, par-

ticularly when the engine is warm. When

opening the cap, you could be scalded by hot

coolant spraying out. There is a risk of injury.

Let the engine cool down before opening the

cap. Wear eye and hand protection when

opening the cap. Open the cap slowly half a

turn to allow pressure to escape.

The coolant may only be checked and cor-

rected when the engine is cool (coolant

temperature below 104 ‡ (40 †). Check-

ing the coolant when the coolant tempera-

ture is above 104 ‡ (40 †) may result in

damage to the engine or to the engine cool-

ing system.

Example

Park the vehicle on a level surface.

Only check the coolant level when the vehi-

cle is on a level surface and the engine has

cooled down.

Turn the SmartKey to position 2 in the igni-

tion lock (Y page 143).

Check the coolant temperature display in

the instrument cluster.

The coolant temperature must be below

104 ‡ (40 †).

Turn the SmartKey to position

0 (Y page 143) in the ignition lock.

Slowly turn cap : half a turn counter-

clockwise to allow excess pressure to

escape.

Turn cap : further counter-clockwise and

remove it.

If the coolant is at the level of marker bar =

in the filler neck when cold, there is enough

coolant in coolant expansion tank ;.

If necessary, add coolant that has been tes-

ted and approved by Mercedes-Benz.

Replace cap : and turn it clockwise as far

as it will go.

For further information on coolant, see

(Y page 365).

ment, such as the engine, radiator and parts

of the exhaust system, can become very hot.

Working in the engine compartment poses a

risk of injury.

Where possible, let the engine cool down and

touch only the components described in the

following.

WARNING

Windshield washer concentrate could ignite if

it comes into contact with hot engine compo-

nents or the exhaust system. There is a risk of

fire and injury.

Make sure that no windshield washer con-

centrate is spilled next to the filler neck.

Example

To open: pull cap : upwards by the tab.

Add the premixed washer fluid.

To close: press cap : onto the filler neck

until it engages.

If the washer fluid level drops below the rec-

ommended minimum of 1 liter, a message
