freezes at a temperature of approx-
imately –11 †. The vehicle is equipped with
an AdBlue ®
preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures below –11 †.
Special additives !
Only use AdBlue ®
compliant with
ISO 22241. Do not add any special addi-
tives to AdBlue ®
and do not dilute it with
water. Doing so may destroy the BlueTEC
exhaust gas aftertreatment system.
Damage resulting from the use of such
additives or from water is not covered by
the Mercedes-Benz implied warranty.
Purity The purity of AdBlue
®
is particularly important
for avoiding malfunctions in the exhaust gas
aftertreatment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, it must not be
returned to the tank as the purity of the fluid
can no longer be guaranteed.
! Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust) lead to increased emission values, system
malfunctions, catalytic converter damage
or damage to the BlueTEC system. Vehicle model Total capacity of
the AdBlue ®
tank GL 350 BlueTEC 31.7 l
