latest, after receiving the first warning mes-
sage via the on-board computer.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the
supply regularly. The engine management
recognizes attempts to operate the vehicle
without DEF, with thinned DEF or with
another reducing agent. After previous warn-
ing messages, the engine management then
prevents a further engine start.
If the DEF level drops below 1.5 US gal (5.5 l),
the first warning message is issued and a
warning tone sounds. After the message
appears for the first time, and under normal
driving conditions, the remaining DEF supply
will last for approximately 1000 miles
(1600 km).
If a reserve mark of 0.8 US gal (3.0 l) is
reached, a second warning message is issued
and a warning tone sequence sounds. After
the first message, the DEF supply will last for
approximately 1200 miles (1900 km). Subse-
quently, you will only be able to start the
engine a further 16 times.
You should immediately add 2.0 US gal (7.6 l)
of DEF ( page 147) or have the DEF supply

reservoir filled at a qualified specialist work-
shop.

management prevents the vehicle from being
driven at a speed exceeding 5 mph (8 km/h).
If the ; Check Engine indicator lamp lights
up, the exhaust gas aftertreatment is faulty or
an emission-related malfunction has occur-
red ( page 211). You will then only be able to

drive a maximum 50 mi (80 km) before the
engine management restricts the number of
starts remaining.
If the exhaust gas aftertreatment is faulty,
have it checked and repaired at a qualified
specialist workshop.
