Coolant
Introduction
This chapter contains information on the following subjects:
Capacity
Checking the coolant level
Replenishing
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

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
201.
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.
1)
The coolant capacity is approximately 1 l greater on vehicles that are fitted with an auxiliary heater
(auxiliary heating and ventilation).
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.
Other coolant additives that do not comply with the correct specifications can
■
significantly reduce the corrosion protection.
207
Any faults resulting from corrosion may cause a loss of coolant and can conse-
■
208
quently result in major engine damage!
208
Do not fill the coolant above the mark
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
■
rage, as otherwise serious engine damage may occur.
