0050Solutions 00B2
The yellow
engine oil level
warning lamp
flashes and the
warning buzzer
sounds after the
engine is started
or while the vehi-
cle is in motion. On vehicles with a diesel engine, the oil level display additionally
appears in the display, e.g.
– 2.0 qts – 2.0 qts(Canada:– 2.0 ltr
– 2.0 ltr).
There is not enough or no oil in the engine.
There is a danger of engine damage.
X Stop the vehicle as soon as possible, paying attention to road
and traffic conditions.
X Check the oil level with the oil dipstick (Y page 251).
X If the engine oil level is correct: have the malfunction rectified
immediately at a qualified specialist workshop.
X If the engine oil level is too low: have the vehicle towed to a
qualified specialist workshop. 00B2
The yellow
engine oil level
warning lamp
lights up and the
warning buzzer
sounds after the
engine is started
or while the vehi-
cle is in motion. The engine oil level is above the maximum level.
There is a risk of damaging the engine or catalytic converter.
X Check the oil level with the oil dipstick (Y page 251).
X If the oil level is too high: have the engine oil extracted as soon
as possible at a qualified specialist workshop.
X If the oil level is correct: have the malfunction rectified as soon
as possible at a qualified specialist workshop. 00B2
On vehicles with
a diesel engine,
the yellow
engine oil level
warning lamp
lights up repeat-
edly during the
journey. There is a malfunction in the engine oil level display.
X Have the vehicle checked immediately at a qualified specialist
workshop. 003F
The yellow cool-
ant level warning
lamp lights up
while the engine
is running. The coolant level is too low.
Never run the engine if the coolant level is too low. The engine
could overheat and be damaged.
X Stop the vehicle as soon as possible, paying attention to road
and traffic conditions.
X Switch off the engine and let it cool down.
X Add coolant and be sure to observe the warning notes
(Y page 253).
X If you need to add coolant frequently, have the engine cooling
system checked at a qualified specialist workshop. Indicator and warning lamps in the instrument cluster

Replace cap 0085on the filler neck and
tighten.
When doing so, make sure that the cap
engages correctly.
X Check the oil level with the oil dipstick
(Y page 251) or on the display
(Y page 250).
X Close the hood. Coolant

WARNING
The engine cooling system is pressurized, par- ticularly when the engine is warm. When
opening the cap, you could be scalded by hotcoolant 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.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and the engine has cooled down. The coolant tem-
perature must be below 122 ‡ (50 †).
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified
specialist workshop. G
WARNING
Coolant contains glycol and is therefore toxic. Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of skin and clothing with soap and water imme-
diately. Change any affected clothing imme-
diately. G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork. Example: cap and coolant expansion tank
Checking the coolant 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 Slowly turn cap 0043half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0043further and remove it.
X Check the coolant level.
If the coolant reaches the maximum mark
on coolant expansion tank 0044, there is
enough coolant in coolant expansion
tank 0044. Engine compartment
253Maintenance and care Z

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
Engine compartmentMaintenance and care

must be used in the system all year round to
ensure anti-corrosion protection and a raised
boiling point – even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys- tem, use only approved corrosion inhibitor/
antifreeze that comply with the Mercedes-
Benz Specifications for Service Products.
We recommend corrosion inhibitor/anti-
freeze that meets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor con- centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least 50%. This way, the engine cool-
ing system is protected against freezing
down to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion inhibi-
tor/antifreeze additive. The water used as
part of the coolant mixture must fulfill certain requirements; these are usually fulfilled by
drinking water. If the water quality is not suf-ficient, you must treat the water.

Important safety notes G
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.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
