Mercedes Benz 2007 sl 550 ユーザーズマニュアル

In areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines which contain these additives, 
Mercedes-Benz recommends the use of 
additives approved by us for use on 
Mercedes-Benz vehicles. Refer to Factory 
Approved Service Products pamphlet for a 
listing of approved product(s). Follow di-
rections on product label.

Do not blend other fuel additives with fuel. 
This only results in unnecessary cost and 
may be harmful to the engine operation.

Damage or malfunction resulting from 
poor fuel quality or from blending addition-
al fuel additives other than those tested 
and approved by us for use on 
Mercedes-Benz vehicles listed in the 
Factory Approved Service Products pam-
phlet are not covered by the 
Mercedes-Benz Limited Warranty.

The engine coolant is a mixture of water 
and anticorrosion/antifreeze, which pro-
vides:

앫

corrosion protection

앫

freeze protection

앫

boiling protection (by increasing the 
boiling point)

The cooling system was filled at the factory 
with a coolant providing freeze protection 
to approximately -22°F (-30°C) and corro-
sion protection.

If the antifreeze mixture is effective to 
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is 
reached at approximately 266°F (130°C).

The coolant solution must be used year 
round to provide the necessary corrosion 
protection and increase in the boil-over 
protection. Refer to Maintenance Booklet 
for replacement interval.

Coolant system design and coolant used 
stipulate the replacement interval. The re-
placement interval published in the 
Maintenance Booklet is only applicable if 
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved 
products of equal specification (see 
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper 
level.
