i
Have the brake fluid renewed every 2
years at a qualified specialist workshop.
There is usually a notice in the engine com-
partment to remind you when the next
brake fluid change is due. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
! Take care not to spill any coolant on
painted surfaces. You could otherwise
damage the paintwork.
When handling, storing and disposing of cool-
ant and antifreeze, please observe the rele-
vant regulations and the safety notes in the
"Service products and capacities" section
(Y page 320). Coolant additive with corrosion/anti-
freeze protection !
Use only approved antifreeze/corrosion
inhibitor that complies with MB Specifica-
tion for Service Products, Sheet Number
325. Using other, non-approved anti-
freeze/corrosion inhibitors may cause
damage to the coolant system and reduce
the engine's service life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
R corrosion protection
R antifreeze protection
R raises the boiling point
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection. Coolant
must be used in the system all year round to
ensure anti-corrosion protection and a raised
boiling point – even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved corrosion inhibitor/
antifreeze that comply with the Mercedes-
Benz Specifications for Service Products. You
will find information about approved corro-
sion inhibitor/antifreeze for your vehicle in
the Maintenance Booklet.
We recommend corrosion inhibitor/anti-
freeze that meets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least 50%. This way, the engine cool-
ing system is protected against freezing
down to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively. Service products and capacities
