144Driving and operatingCaution
Avoid contact of the paintwork withAdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue preheater,
the emissions reduction at low
temperatures is ensured. The AdBlue
preheater works automatically.
Note
Frozen and again liquefied AdBlue is usable without quality loss.
The typical AdBlue consumption is
approx. 0.85 l per 1000 km, but can
also be higher depending on driving
behaviour (e.g. high load or towing).
Level warnings
Depending on the calculated range of AdBlue, different messages are
displayed in the Driver Information
Centre. The messages and the
restrictions are a legal requirement.
1. The first possible warning is Top
up emissions additive: Starting
prevented in 2400 km .
When switching on the ignition,
this warning will show up once
briefly with the calculated range.
Additionally, control indicator u
will illuminate and a chime will
sound. Driving is possible without
any restrictions.
When driving, the message is
displayed every 300 km until the
additive tank has been topped-up.
2. The next warning level is entered with a range below 600 km. Themessage with the current range
will always be displayed when
ignition is switched on.
Additionally, control indicator u
will flash and a chime will sound.
Refill AdBlue before entering the
next warning level.
When driving, the message is
displayed every 30 seconds until
the additive tank has been
topped-up.
3. The last warning level is entered when the AdBlue tank is empty.Restart of the engine is not
possible. The following warning
message will be displayed:
Top up emissions additive:
Starting prevented
Additionally, control indicator u
will flash and a chime will sound.
Refill the tank to a level of at least
5 l of AdBlue, otherwise restarting
of the engine is not possible.
High emission warnings In the event of a fault with the
emissions control system, different
messages are displayed in the Driver
Information Centre. The messages
and the restrictions are a legal
requirement.
1. If a fault is detected for the first time, the warning Emissions fault
is displayed.
Additionally, control indicators u,
C and Z will illuminate and a
chime will sound. Driving is
possible without any restrictions.
If it is a temporary fault, the alert
disappears during the next
