XInsert oil dipstick:back into the guide tube
as far as it will go and remove it again.
If the level is between minimum mark =and
maximum mark ;, the oil level is correct.
XIf the oil level has dropped to or below mini-
mum mark=, open cap ?and add engine oil
(
Ypage 222).
The difference in quantity between marks ;
and =is approximately 2 qt (2 l).
XInsert the oil dipstick into the guide tube as far
as it will go.
XClose the hood (Ypage 219).
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 222)
or
XHave engine oil siphoned off.
Adding 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 218).
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 221) or on the display (Ypage 220).
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.
222Engine compartment
Maintenance and care
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 218).
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 283). 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 5 minutes, switch off the
engine and allow it to cool down.
XCheck the coolant level again and add coolant
if necessary.
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 277).
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 2 year sat a
qualified specialist workshop. Observe the infor- mation on brake fluid in the "Technical data"
section (
Ypage 283).
Check the brake fluid level regularly, e.g. weekly
or when refueling.

Maintenance and care
Z
Engine oils are differentiated according to:
Rengine oil brand
Rquality grade (sheet number)
RSAE class (viscosity)
Subsequently have the engine oil changed at the
earliest possible opportunity.
Interval for oil change
The on-board computer automatically shows
the date for the next oil change as an event
message in the display.
Only by using engine oil with a particularly high
quality grade, e.g. according to Sheet Number
228.51 of the Mercedes-Benz Specifications for
Service Products, can the maximum interval for
oil change be achieved.
We recommend having the oil changed at a
qualified specialist workshop.

Information about oil consumption
!If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func-
tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distances,
you should drive on a highway or on rural
roads for 20 minutes every 310 miles (500 km). This ensures sufficient regenera-
tion of the diesel particle filter.
Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 qt (1.0 l)of engine oil
over a distance of 620 miles (1000 km).
Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous
operating conditions.
Ryou frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (
Ypage 220).
