Oil level within range CThe engine must be topped up with oil so that the oil level at least reaches the
range B
.
The engine consumes a little oil. The oil consumption may be as much as 0.5 l/
1 000 km depending on your style of driving and the conditions under which you operate your vehicle. Consumption may be slightly higher than this during thefirst 5 000 kilometres.
The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range
A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The indicator light in the instrument cluster will indicate whether the oil level is
too low » page 17 ,
Engine oil . Check the oil level using the dipstick as soon
as possible. Add oil accordingly.
CAUTION
The oil level must not exceed the range A » Fig. 160 – there is a risk of damaging
the exhaust system.
Replenishing
First read and observe the introductory information and safety warn-
ings
on page 202.
›
Check the oil level » page 203.
›
Unscrew the cap of the engine oil filler opening » Fig. 158
on page 201.
›
Replenish the oil in portions of 0.5 litres in accordance with the correct specifi-
cations » page 203 .
›
Check the oil level » page 203.
›
Carefully screw on the oil filler opening cap and push the dipstick in fully.
Changing
First read and observe the introductory information and safety warn-ings
on page 202.
The engine oil must be changed according to prescribed service inter-vals » page 182 or according to the service interval display » page 30.

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze written on the antifreeze expansion tank » Fig. 161 on page 205.
204General Maintenance
WARNING■The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 199.■
Do not continue your journey if for some reason it is not possible to fill
with coolant under the current circumstances. Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect.■
A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 161 on page 205.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

Inspecting the coolant level
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of coolant in the coolant expansion bottle » Fig. 161.
Coolant level above mark
A
No coolant may be added.
The level may also rise slightly above the
A
marking when the engine is hot.
Coolant level between markings
A
and
B
Coolant may be added.
The coolant level must lie between the
A
and
B
markings when the engine is
cold.
Coolant level below mark
B
Coolant must be added.
Top up the coolant level to between the
A
and
B
markings when the engine is
cold.
1)
The coolant capacity is approximately 1 l greater on vehicles that are fitted with an auxiliary heater
(auxiliary heating and ventilation).
