OM651 4-cylinder diesel engine:
At outside temperatures between 32 ‡ (–0 †)
and 86 ‡ (30 †), the oil level can be checked
when the engine is cold.
Measuring the engine oil when the engine is cold
is less precise than measuring when the engine
is at normal operating temperature.
When the appropriate warning is shown in the
display
XAdd engine oil (Ypage 223)
or
XHave engine oil siphoned off.
Add engine oil
GWARNING
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.
!The alternator is located below the engine
oil filler neck. If engine oil spills onto the alter-
nator, there is a danger of alternator damage.
Be very careful when adding engine oil.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
!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.
!Do not use any additives in the engine oil.
This could damage the engine.
XOpen the hood (Ypage 219).
XUnscrew and remove cap ?.
XAdd engine oil.
XReplace cap?on the filler neck and tighten.
When doing so, make sure that the cap
engages correctly.
XCheck the oil level with the oil dipstick
(Ypage 222) or on the display (Ypage 221).
XClose the hood.
Coolant
GWARNING
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.
Only check the coolant level and/or fill the cool-
ant if the vehicle is on a level surface and the
engine has cooled down. The coolant tempera-
ture 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 spe-
cialist workshop.
GWARNING
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 painted
surfaces. You could otherwise damage the
paintwork.

Example: cap and coolant expansion tank
Checking the coolant level
XStop your vehicle as far away from traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 219).
XSlowly turn cap:half a turn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it.
XCheck the coolant level.
If the coolant reaches the maximum mark on
coolant expansion tank ;, there is enough
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under the minimum mark
on coolant expansion tank ;, add coolant to
the maximum mark.
Observe the information on coolant mixture
ratio and water quality in the "Technical data"
section (
Ypage 285). To prevent damage to
the engine cooling system, use only approved
corrosion inhibitor and antifreeze that com-
plies with the Mercedes-Benz Specifications
for Service Products.
XReplace cap :and turn it clockwise to
tighten.
XStart the engine.
XAfter approximately five minutes, switch off
the engine again and allow it to cool down.
XCheck the coolant level again and add coolant
if necessa ry.
XClose the hood.
Brake fluid
GWARNING
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 products and
capacities" section (
Ypage 278).
GWARNING
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 rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every two years at
a qualified specialist workshop. Observe the
information on brake fluid in the "Technical
data" section (
Ypage 284).
Check the brake fluid level regularly, e.g. weekly
or when refueling.

Coolant
Important safety notes
GWARNING
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 painted
surfaces. You could otherwise damage the
paintwork.
When handling coolant, observe the important
safety notes for service products (
Ypage 278).
Coolant additive with antifreeze
requirements
!Use only approved antifreeze/corrosion
inhibitor that complies with MB Specification for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may cause damage to the cool-
ant system and reduce the engine's service
life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaises the boiling point
When the vehicle is first delivered, it is filled with
a coolant mixture that ensures adequate anti-
freeze/corrosion protection. Coolant 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 tempera-
tures. To prevent damage to the engine cooling sys-
tem, use only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz
Specifications for Service Products.
We recommend corrosion inhibitor/antifreeze
that meets the requirements in MB Specifica-
tions 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:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55 % otherwise heat will not be
dissipated as effectively. At 55 %,the engine
cooling system is protected against freezing
down to approximately -49 ‡ (-45 †).
If there has been coolant loss, do not refill only
with water. If the vehicle has lost coolant, add
equal parts water and corrosion inhibitor/anti-
freeze additive. The water used as part of the
coolant mixture must fulfill certain require-
ments; these are usually fulfilled by drinking
water. If the water quality is not s
ufficient, you
must treat the water.
