Operation

Engine compartment

Hood

Opening

The hood lock release lever is located to

the left of the steering wheel under the

dashboard.

1 Hood lock release lever

왘 Pull lever 1 downwards.

The hood is unlocked and handle 2

will extend out of the radiator grille.

2 Handle for opening the hood

왘 Pull handle 2 to its stop out of

radiator grille.

왘 Pull up on the hood (do not pull up on

the handle) and then release it.

The hood will be automatically held

open at shoulder height by gas-filled

struts.

Warning! G

Do not pull the release lever while the

vehicle is in motion. Otherwise the hood

could be forced open by passing air flow.

To avoid damage to the windshield

wipers or hood, never open the hood if

the wiper arms are folded forward away

from the windshield.

Warning! G

To help prevent personal injury, stay clear of

moving parts when the hood is open and the

engine is running. Make sure the hood is

properly closed before driving. When closing

the hood, use extreme caution not to catch

hands or fingers.

The radiator fan may continue to run for

approximately 30 seconds or even restart

after the engine has been turned off. Stay

clear of fan blades.

Operation

Engine compartment

Closing

왘 Let the hood drop from a height of

approximately 1 ft (30 c m).

The hood will lock audibly.

왘 Check to make sure the hood is fully

closed.

If you can raise the hood at a point

above the headlamps, then it is not

properly closed. Open it again and let it

drop with somewhat greater force.

Engine oil

The amount of oil your engine needs will

depend on a number of factors, including

driving style. Higher oil consumption can

occur when

앫 the vehicle is new

앫 the vehicle is driven frequently at

higher engine speeds

Engine oil consumption checks should only

be made after the vehicle break-in period.

Warning! G

If you see flames or smoke coming from the

engine compartment, or if the coolant tem-

perature gauge indicates that the engine is

overheated, do not open the hood. Move

away from vehicle and do not open the hood

until the engine has cooled. If necessary,

call the fire department.

Warning! G

The engine is equipped with a transistorized

ignition system. Because of the high voltage

it is dangerous to touch any components

(ignition coils, spark plug sockets, diagnos-

tic socket) of the ignition system

앫 with the engine running

앫 while starting the engine

앫 if ignition is “on” and the engine is

turned manually

Warning! G

Be careful that you do not close the hood on

anyone.

Do not use any special lubricant addi-

tives, as these may damage the drive

assemblies. Using special additives not

approved by Mercedes-Benz will

restrict your warranty entitlement.

More information on this subject is

available at any Mercedes-Benz

Center.

Coolant level

The engine coolant is a mixture of water

and anticorrosion/antifreeze. To check

the coolant level, the vehicle must be

parked on level ground and the engine

must be cool.

The coolant expansion tank is located on

the passenger side of the engine compart-

ment.

1 Coolant expansion tank

2 Cap

왘 Using a rag, turn cap 2 slowly approx-

imately one half turn to the left to

release any excess pressure.

왘 Continue turning the cap to the left and

remove it.

The coolant level is correct if the level

앫 for cold coolant: reaches the black

top part of the reservoir

앫 for warm coolant: is approx. 0.6 in

(1.5 cm) higher

왘 Add coolant as required.

왘 Replace and tighten cap.

For more information on coolant, see

“Coolants” (

컄 page 394).

Warning! G

In order to avoid any possibly serious burns:

앫 Use extreme caution when opening the

hood if there are any signs of steam or

coolant leaking from the cooling system,

or if the coolant temperature gauge indi-

cates that the coolant is overheated.

앫 Do not remove pressure cap on coolant

reservoir if coolant temperature is

above 158°F (70°C). Allow engine to

cool down before removing cap. The

coolant reservoir contains hot fluid and

is under pressure.

앫 Using a rag, slowly open the cap

approximately

turn to relieve excess

pressure. If opened immediately, scald-

ing hot fluid and steam will be blown out

under pressure.

앫 Do not spill antifreeze on hot engine

parts. Antifreeze contains ethylene

glycol which may burn if it comes into

contact with hot engine parts.

Operation

Engine compartment

Battery

Your vehicle’s battery is located in the

engine compartment on the right hand

side (컄 page 360).

The 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 the battery, always use

batteries approved by Mercedes-Benz.

If you do not intend to operate your vehicle

for an extended period of time, consult an

authorized Mercedes-Benz Center about

steps you need to observe.

Batteries contain materials that can harm

the environment if disposed of improperly.

Recycling of batteries is the preferred

method of disposal. Many states require

sellers of batteries to accept old batteries

for recycling.

Observe all safety instructions

and precautions when handling

automotive batteries.

Risk of explosion

Keep flames or sparks away

from battery. Do not smoke.

Battery acid is caustic. Do not

allow it to come into contact

with skin, eyes or clothing.

In case it does, immediately

flush affected area with clear

water and seek medical help if

necessary.

Wear eye protection.

Keep children away.

Follow the instructions in this

Operator's Manual.

Windshield washer system and

headlamp cleaning system*

The windshield washer reservoir is located

in the engine compartment.

1 Washer fluid reservoir cap

Fluid for the windshield washer system and

the headlamp cleaning system* is supplied

from the windshield washer reservoir. It

has a capacity of:

앫 3.2 US qt (3.0 l) in vehicles without

headlamp cleaning system*

앫 6.4 US qt (6.0 l) in vehicles with

headlamp cleaning system*

During all seasons, add MB Windshield

Washer Concentrate “S” to water. Premix

the windshield washer fluid in a suitable

container.

왘 Refill the reservoir with MB Windshield

Washer Concentrate and water (or

commercially available premixed

windshield washer solvent/antifreeze,

depending on ambient temperatures).

Always use washer solvent/antifreeze

where temperatures may fall below the

freezing point. Failure to do so could

result in damage to the washer

system/reservoir.

For more information, see “Windshield

washer and headlamp cleaning system*”

(

컄 page 396).

Only use washer fluid which is suitable

for plastic lenses. Improper washer

fluid can damage the plastic lenses of

the headlamps.

Warning! G

Washer solvent/antifreeze is highly flamma-

ble. Do not spill washer solvent/antifreeze

on hot engine parts, because it may ignite

and burn. You could be seriously burned.
