Let an overheated engine cool down before
opening the hood. If there is afire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment,s uch 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.
!Do not use your hands to push the hood
down. You could damage it otherwise.
XHold support strut ?and lift the hood
slightly.
XGuide support strut ?towards retainer =
and apply slight pressure to make it engage.
XLower the hood and allow it to fall with
momentum from aheight of approximately
1ft( 30 cm).
The hood locks audibly.
XCheck that the hood is correctly locked.
If the hood can be raised slightly, it is not
properly engaged. If the hood is not correctly
engaged, open the hood again. Let the hood
fall with alittle more momentum.
Overview of the engine compartment
Engin ecompartment (example)
:
Engin eoil filler neck cap (Ypage 242)
;Brake fluid reservoir cap (Ypage 245)
=Coolant expansion tank cap (Ypage 244)
?Washer fluid reservoir cap (Ypage 246)
Regularly check the fluid level and the assembly
for leaks. If you detect fluid loss, e.g. oil flecks on the vehicle parking space, consult aqualified
specialist workshop immediately.
Engine oil
General notes
!Engin eoil gets dirty in the course of opera-
tion and its quality and volume are gradually
diminished. Regularly check the oil level, and top up or have it replaced as needed.
Observe the information on approved engine
oils and oil consumption under "Service prod-
ucts and capacities" (
Ypage 298).
You can check the oil level in the engine:
Rwith the oil dipstick
Checking the oil level using the oil dip-
stick
GWARNING
Opening the hood when the engine is over-
heated or when there is afire in the engine
compartment could expose you to hot gases

Maintenance and care
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tank
Checkingt he coolant level
XStop your vehicle as far awayf rom traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 241).
XSlowly turn cap :half aturn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it from cool-
ant expansion tank ;.
XCheck the coolant level.
If the coolant is up to marker bar =in the
filler neck when cold, there is asufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 0.59 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is asufficient amount of
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under marker bar =in
the filler neck, add coolant.
Observe the information on the correct cool-
ant mixture ratio and the required water qual-
ity under "Service products and capacities"
(
Ypage 300). To prevent damage to the
engine cooling system, use only approved
corrosion inhibitor/antifreeze that complies
with the Mercedes-Benz Specifications for
Service Products.
XReplace cap :and turn it clockwise to
tighten.
XStart the engine.
XSet the temperature in the vehicle interior to
the maximum output on the air-conditioning
system control panel.
XAfter approximately 5minutes ,switch off the
engine and allow it to cool down.
XCheck the coolant level againa nd add coolant
if necessary.
XClose the hood.

The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,vapo rpockets may form in the

hard .This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui drenewe dat

linings. Visi taqualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake flui dcorrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake flui drenewe devery 2years at a
