Checking and refilling levels
– Briefly run the engine at idle speed until the operating tempera-
ture is reached and then stop.
– Wait two minutes.
– Pull out the dipstick. Wipe the dipstick with a clean cloth and
insert it again, pushing it in as far as it will go.
– Then pull it out once more and check the oil level ⇒ Fig. 108.
Top up with engine oil if necessary.
Oil level in area A
Do not add oil
⇒ .
Oil level in area B
You can add oil, but keep the level in this zone.
Oil level in area C
Oil
must be added. Afterwards, the oil level should be in the lined area
B.
Depending on how you drive and the conditions in which the vehicle is
used, oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely
to be higher for the first 5000 km. For this reason the engine oil level must
be checked at regular intervals, preferably when filling the tank and before
a journey.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 209.

CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a Technical Serv-
ice. 
Topping up engine oil 
Top up gradually with small quantities of engine oil.

Before opening the bonnet, read and observe the warnings ⇒ 
in
Working on components in the engine compartment on page 209.
– Unscrew cap from engine oil filler opening ⇒ 
Fig. 109.
– Top-up oil in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using
small quantities, wait a while and check the oil level before
adding any more oil. 

214Checking and refilling levels
–As soon as the oil level is in area B
, carefully close the cap.
The position of the oil filler opening is shown in the corresponding engine
compartment illustration ⇒ page 267.
Engine oil specification ⇒ page 211.
WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a specialised work-
shop.
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust system. 
Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule. We recommend that you have the engine oil changed by a Technical Serv-
ice.
The oil change intervals are shown in the Maintenance Programme.
WARNING
Only change the engine oil yourself if you have the specialist knowledge
required!
● Before opening the bonnet, read and observe the warnings
⇒ page 209.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries, such as acid burns, caused by
splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent oil from running down your arm.
● Wash your skin thoroughly if it comes into contact with engine oil.
● Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist knowledge required, we recommend that you have the engine oil and
filter changed by a Technical Service.
● Never pour oil down drains or into the ground.
● Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil. 

Checking and refilling levels
Charging the battery
Terminals for charging the battery are fitted in the engine
compartment.
– Note the warnings ⇒ 
in Important safety warnings for han-
dling a vehicle battery on page 218 and ⇒ .
– Switch off all electrical equipment. Remove the ignition key.
– Raise the bonnet ⇒ page 210.
– Open the battery cover.
– Connect the charger clamps as described to the positive pole of
the battery (+) and, exclusively to an earth on the bodywork
(–).
– Only use a charger which is compatible for use with 12 V nomi-
nal voltage batteries. The charge must not exceed a voltage of
15 V.
– Now connect the battery charger to the power socket and switch
on.
– After charging the battery: switch off the battery charger and
disconnect the power socket cable.
– Finally disconnect the charger cables from the battery.
– Replace the battery cover correctly.
– Close the bonnet ⇒ page 210.
Important: Before you charge the battery make sure you read the manufac-
turer's instructions for using the battery charger.
WARNING
Never charge a battery that has frozen: replace battery! Failure to do so
may lead to an explosion.
Note
Use only the terminals in the engine compartment to charge the battery. 
Replacing the battery
The new battery should have the same specifications (am-
perage, load and voltage) as the used battery.
Your vehicle is equipped with an intelligent power management system to
control the distribution of electrical energy ⇒ page 187. The power manage-
ment function ensures that the battery is charged much more efficiently
than on vehicles without a power management system. To maintain this
function after replacing the battery, we recommend that the replacement
battery used is of the same make and type as the original fitted battery. To
make proper use of the power management function after the battery has
been changed, have the battery coded to the power management mode at a
specialised workshop.
CAUTION
● Some vehicles, for example those with the Start-Stop system* are fitted
with a special battery (AGM-type or EFB-type battery). If any other type of
battery is fitted, the Start-Stop function may be considerably reduced and
the vehicle may not stop on repeated occasions.
● Make sure that the vent hose is always attached to the original opening
on the side of the battery. Gases or battery acid can otherwise escape and
possibly cause damage.
● The battery holder and clamps must always be correctly secured. 
