DEF (BlueTEC vehicles only)
Important notes on use
To function properly, BlueTEC exhaust gas
aftertreatment must be operated with the
reducing agent DEF. Adding DEF is one of the
tasks performed during maintenance. Under
normal operating conditions, a tank of DEF
lasts until the next service due date.
When the supply of DEF is almost used up, the
Check Check Additive Additive See See Operator's Operator's Manual Manual
message is shown in the multifunction dis-
play.
When the DEF supply drops to a minimum, the
Remaining Starts: 16 Remaining Starts: 16 message is shown
in the multifunction display.
If the
Remaining Starts: 16 Remaining Starts: 16 message
appears in the multifunction display, you can
start the engine another 16 times. If DEF is
not refilled, you will subsequently be unable
to start the engine.
X
Add at least 1 gal (3.8 l) of DEF.
X Switch on the ignition for at least 60 sec-
onds.
X
Start the engine.
i Have the DEF tank refilled at a qualified
specialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
an authorized Mercedes-Benz Center with
any questions or, if necessary, contact Road-
side Assistance (
Y
page 25).
If the outside temperature is below 12 ‡
(Ò11 †) it may be difficult to top up. If DEF is
frozen and there is an active warning indica-
tor, it may not be possible to add DEF. Park
the vehicle in a warmer place, e.g. in a garage,
until DEF has become fluid again. It will then
be possible to add DEF again. Alternatively,
have the DEF tank refilled at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust
gas aftertreatment and DEF is available at any
authorized Mercedes-Benz Center.
