Important safety notes
H
Environmental note
Dispose of DEF in an environmentally respon-
sible manner.
! Only use DEF in accordance with
ISO 22241. Never mix DEF with additives or
thin it with tap water. The exhaust gas after-
treatment may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet 352.0.
Damage that results from the use of addi-
tives or tap water leads to the loss of the
New Vehicle Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
! DEF is not a diesel additive and must not
be mixed with fuel in the tank. Even small
amounts of DEF can cause engine damage.
Damage that results from the blending of
DEF will not be covered by the New Vehicle
Limited Warranty.
The exhaust gas aftertreatment requires a
reducing agent, Diesel Exhaust Fluid (DEF), in
order to function correctly.
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and
primarily cause irritation of the:
