Hood
Important safety notes G
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. G
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. G
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:
R switch off the ignition
R never reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
R remove jewelry and watches
R keep items of clothing and hair, for exam-
ple, away from moving parts G
WARNING
The fuel injection system operates with a high voltage. If you touch the live components, you could receive an electric shock. There is a risk
of injury.
Never touch components of the fuel injection
system when the ignition is switched on.
The live components of the fuel injection sys-
tem are, for example, the injectors. G
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.
If you have to carry out work in the engine
compartment, only touch the following com-
ponents:
R Hood
R Oil dipstick
R Engine oil filler neck cap
R Washer fluid reservoir cap
R Coolant expansion tank cap
Opening the hood !
Make sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield
wipers or the hood. 248

Regularly check the fluid level and the assem- bly for leaks. If you detect fluid loss, e.g. oil
flecks on the vehicle parking space, consult a qualified specialist workshop immediately. Engine oil
General notes !
Engine oil gets dirty in the course of oper-
ation and its quality and volume are gradu- ally diminished. Regularly check the oil
level, and top up or have it replaced as nee-
ded.
Observe the information on engine oils and oil
consumption in the "Technical data" section
(Y page 322).
You can check the oil level in the engine:
R on the display of the on-board computer
R with the oil dipstick Checking the oil level shown in the dis-
play If at extremely low temperatures no engine oil
level is displayed after 5 minutes, repeat the
engine oil level check after another
5 minutes.
If an oil level reading is still not displayed,
check the engine oil level with the dipstick
(Y page 251). Have the engine oil level
checked at a qualified specialist workshop.
Only check the oil level when the engine is at
normal operating temperature.

Adding coolant
X If the coolant drops under the minimum
mark on coolant expansion tank 0044, add
coolant to the maximum mark.
Observe the information on coolant mix-
ture ratio and water quality in the "Techni-
cal data" section (Y page 325). To prevent
damage to the engine cooling system, use
only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz Specifications for Service Products.
X Replace cap 0043and turn it clockwise to
tighten.
X Start the engine.
X After approximately 5 minutes, switch off
the engine and allow it to cool down.
X Check the coolant level again and add cool-
ant if necessary.
X Close the hood. Brake fluid

WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels of the respective original containers. Always
store service products sealed in their original containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 318).G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident. You should have the brake fluid renewed at
the specified intervals.
! Brake fluid corrodes paint, plastic and
rubber. If paint, plastic or rubber has come into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years at
a qualified specialist workshop. Observe the
information on brake fluid in the "Technical
data" section (Y page 324). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immedi-
ately for leaks. Also check the thickness of the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not cor-
rect the malfunction. 254
