list of the engine oils and oil filters that have
been tested and approved in accordancew ith
Mercedes-Benz Specifications for Service
Products is availableata ny authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick ,add 1.1 US qt (1.0 liter) of
engine oil.
XReplace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely.

Brake fluid
GWARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low,v aporpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui dreneweda t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(
Ypag e315).
The brake flui dchange interval scan be found in
the Maintenance Booklet.
Only use brake flui dapproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval3 31.0.
Information about approved brake flui dcan be
obtained at any qualified specialist workshop or
on the Internet at

qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypag e315).
The coolant is amixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).
