187Checking and refilling levels
Topping up engine oil
– Check the engine oil level ⇒ page 186, Checking the engine oil
level.
– Unscrew the cap from the filler opening.
– Put in the specified grade of oil 0.5 litres at a time ⇒ page 184.
– Check the oil level ⇒ page 186.
– Replace the oil filler cap carefully and push the dipstick all the
way in.
Changing engine oil
Engine oil must be changed with the frequency indicated in the Mainte-
nance Programme or according to the service interval indicator ⇒ page 59.
CAUTION
Do not mix engine oil with additives. Risk of damage to the engine! Damage
caused by these products is not covered by the warranty.
Note
Wash your skin thoroughly if it comes into contact with engine oil.
Coolant
General notes
The cooling system is factory-filled with an anti-freeze product.
Coolant consists of a mixture of water and 40% anti-freeze additive. This
mixture gives the required anti-freeze protection at temperatures down to
+25 °C (+77 °F) and protects the cooling and heating system against corro-
sion. It also prevents scaling and raises the boiling point of the coolant con-
siderably.
The coolant concentration must not be reduced by adding water, even in
warmer seasons or in warm countries. The concentration of the anti-freeze
additive in the coolant must be at least 40 %.
If greater anti-freeze protection is required in very cold climates, the propor-
tion of the anti-freeze additive can be increased, but only up to 60 % (anti-
freeze protection down to approx. -40 °C (-40 °F). Any excess in this propor-
tion would reduce the anti-freeze protection and affect the cooling effect.
Vehicles for countries with cold climate are are supplied with coolant protec-
tion down to around -35 °C (-31 °F). The proportion of the antifreeze addi-
tive in these countries should always be at least 50 %.
The type of anti-freeze to be used for topping up is indicated on the coolant
tank cover ⇒ Fig. 126.
