●In unusual situations involving a grossly malfunctioning
engine, a burnt smell may indicate severe and abnormal
catalyst overheating.
If this occurs, the vehicle should be stopped in a safe
place, the engine switched off and the vehicle allowed to
cool. Once the engine is cool, a service, including a tune-
up to the manufacturer’s sp ecifications, should be carried
out immediately.Bonnet

Engine oil
E01000401142
To check and refill engine oil
The engine oil used has a significant effect on the engine’s per-
formance, service life and startability. Be sure to use oil of the
recommended quality and
appropriate viscosity.
All engines consume a certain amount of oil during normal
operation, and engine oil consumption is greatly influenced by
payload, engine speed, etc. Ther efore, it is important to check
the oil level at regular intervals or before starting a long trip.
This check must be made with the engine warm but not run-
ning. Park the vehicle on a level surface, stop the engine, and
then wait a few moments to allow the engine oil in circulation
to return to the oil pan to ensure accurate measurement.
Remove the dipstick and wipe it with a clean cloth. Reinsert
the dipstick as far as it goes. Remove the dipstick and read the
oil level, which should always be within the range indicated.
If the oil level is below the specified limit, remove the cap
located on the cylinder head cover and add enough oil to raise
the level to within the specified range.
Be sure to use the specified e ngine oil and do not mix various
types of oil. Also, avoid mixing different makes of oil together
if possible.
After adding oil, cl ose the cap securely.
Use only the recommended oils with an MB classification as
specified in this manual.

NOTE●Engine oil consumption is greatly influenced by payload,
engine speed, etc. It may reach 1.0 lit./1,000 km (620
miles) depending on the style of driving.
● The engine oil will deteriorate rapidly if the vehicle is
subjected to severe conditions (for example, repeated
operation on rough roads, in mountainous regions, on
roads with many uphill and downhill gradients, or over
short distances). Consequently, the oil will require earlier
replacement.
● For handling used engine oils, refer to page 7.1500 models with turbocharger

Selection of engine oil
Petrol-powered vehicles
Except for vehicles with turbocharger

● Select engine oil of the proper SAE viscosity number
according to the atmosp heric temperature.
● Use engine oil conforming to the following classification:
• “MB 229.1” or higher
NOTE● Use of additives is not recommended since they may
reduce the effectiveness of ad ditives already in the engine
oil. It may result in failure of the mechanical assembly. Vehicles with turbocharger


● Select engine oil of the proper SAE viscosity number
according to the atmo spheric temperature.
● Use engine oil conforming to the following classification:
• ACEA classification: “For service A1/B1, A3/B3, A3/B4 or A5/B5”
• API classification: “For service SG” or higher

NOTE●Use of additives is not recommended since they may

the engine oil. It may result in failure of the mechanical
assembly.
● SAE 5W-30 engine oil can be used to improve engine
startability in very cold weather areas where the lowest
atmospheric temperature is below the range shown in the
illustration.
In this case, use engine o il conforming to the following
classification: • ACEA classification: “For service A3/B3, A3/B4 or A5/B5”
• API classification: “For service SG” or higher

Engine coolant
E01000500830
To check the coolant level
A translucent coolant reserve tank
is located in the engine com-
partment.
Except for petrol-powered vehicles with turbocharger
The coolant level in this tank should be kept between the
“LOW” and “FULL” marks when measured while the engine is
cold.

Check the coolant level in the reserve tank. The reserve tank lid
is equipped with a dipstick.
Remove the dipstick and wipe it with a clean cloth. Reinsert
the dipstick as far as it goes. Remove the dipstick and read the
coolant level, which should always be within the range “F”
(FULL) or “L” (LOW) while the engine is cold.
To add coolant
The cooling system is a closed system and normally the loss of
coolant should be very slight. A noticeable drop in the coolant
level could indicate leakage. If this occurs, we recommend that
you have the system checked as soon as possible.

Except for vehicles with turbocharger
If the level drops below the “LOW” level on the reserve tank,
open the lid and add coolant to “FULL” level.
If the reserve tank is completely empty, remove the radiator
cap (A) and add coolant until the level reaches the filler neck.

If the level drops below the “L” (LOW) level on the dipstick,

Anti-freeze
The engine coolant contains an ethylene glycol anti-corrosion
agent. The cylinder head and wa ter pump housing are cast alu-
minium alloy, and periodic changing of the engine coolant is
necessary to prevent corrosion of these parts.
Use a High-quality ethylene glycol based coolant. This has
excellent protection against corros ion and rust formation of all
metals including aluminium and can avoid blockages in the
radiator, heater, cylinder head, engine block, etc.
Because of the necessity of this anti-corrosion agent, the cool-
ant must not be replaced with plain water even in summer. The
required concentration of anti -freeze differs depending on the
expected ambient temperature.
During cold weather
If the temperatures in your ar ea drop below freezing, there is a
danger that the coolant in the engine or radiator could freeze
and cause severe damage to the engine and/or radiator. Add a
sufficient amount of anti-freeze to the coolant to prevent it
from freezing.
The engine coolant mixture used at the factory provides protec-
tion against freezing for temperat ures as low as approximately
-30 °C. The concentration should be checked before the start of
cold weather and anti-freeze added to the system if necessary.
WARNING!
●Do not open the reserve tank while the engine is hot.
The coolant system is under pressure and any hot
coolant escaping coul d cause severe burns.

CAUTION!
●
Do not use alcohol or me thanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze can
cause corrosion of the aluminium components.
● For effective anti-corro sion and anti-freeze per-
formance, keep the anti -freeze concentration within
a range of 45 to 60 %.
Concentrations exceeding 60 % will result in a
reduction of both the an ti-freeze and cooling per-
formance, thus adversel y affecting the engine.
●Do not top up with water only.
Water by itself reduces th e rust-protective and anti-
freeze qualities of the cool ant and has a lower boil-
ing point. It can also cause damage to the cooling
system if it should freeze. Do not use tap water, as it
can cause corrosion and rust formation.
