!Excess oil must be siphoned or drained 
off. It could cause damage to the 
engine and catalytic converter not 
covered by the Mercedes-Benz Limited 
Warranty.
!Only use approved engine oils. For a 
listing of approved engine oils, refer to 
the Factory Approved Service Products 
pamphlet in your vehicle literature port-
folio.
In addition, check the oil filler cap for 
important information pertaining to the 
engine oil needing to meet a specific 
Mercedes-Benz specification (e.g. MB 
229.5). If such information is printed 
on the oil filler cap, only use an engine 
oil from the list of approved engine oils 
in the Factory Approved Service Prod-
ucts pamphlet that meets the specifi-
cation indicated on the oil filler cap.  
Using engine oils of other specification 
may cause the FSS to incorrectly deter-
mine the next service interval and will 
result in engine damage not covered by 
the Mercedes-Benz Limited Warranty.

Mercedes-Benz Center check the ABC 
system.
Coolant
!Excess oil must be siphoned or drained 
off. It could cause damage to the 
engine and catalytic converter not 
covered by the Mercedes-Benz Limited 
Warranty.
Warning!
G
In order to avoid any possibly serious burns:
Use extreme caution when opening the 
hood if there are any signs of steam or 
coolant leaking from the cooling system, 
or if the coolant temperature gauge indi-
cates that the coolant is overheated.
Do not remove pressure cap on coolant 
reservoir if engine temperature is above 
158°F (70°C). Allow engine to cool 
down before removing cap. The coolant 
reservoir contains hot fluid and is under 
pressure.
Using a rag, slowly open the cap approx-
imately 
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding 
hot fluid and steam will be blown out un-
der pressure.
Do not spill antifreeze on hot engine 
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.
