Engine oils
Engine oils are specifically tested for their 
suitability in our engines and durability for 
our service intervals. Therefore, only use 
approved engine oils and oil filters 
required for vehicles with Maintenance 
System (U.S. vehicles) or FSS PLUS 
(Canada vehicles). For a listing of approved 
engine oils and oil filters, refer to the 
Factory Approved Service Products 
pamphlet (USA only), or contact an 
authorized Mercedes-Benz Center.

Warning!
G
During vehicle operation, the boiling point of 
the brake fluid is continuously reduced 
through the absorption of moisture from the 
atmosphere. Under extremely strenuous 
operating conditions, this moisture content 
can lead to the formation of bubbles in the 
system, thus reducing the system’s 
efficiency.
Therefore, the brake fluid must be replaced 
regularly. Refer to your vehicle’s 
Maintenance Booklet for replacement 
interval.
