Driving a truck with a Euro 4 or Euro 5 engine
Trucks with ADR
Bear in mind that the switch
ADR
is only for use in
emergencies. When the engine is switched off, a
process begins to pump clean the
AdBlue
nozzle and
AdBlue
supply lines. The process takes about 90
seconds and during this time the
ADR
switch must be
switched on. It is especially important to do this in
cold weather as there is a risk of the solution freezing.
The process is not carried out if the
ADR
switch is
used before or during the process.
OBD
The truck is equipped with OBD
(On-Board Diagnostics).
MIL-
symbol
(MIL = Malfunction Indicator Lamp),
located bottom
left on the instrument panel will come on if there is an
emission-related fault. The reason for the lamp being
lit can be investigated during the next stop. If the lamp
lights, the truck should be driven to an authorised
Volvo workshop for checking. There is a delay in the
system that can cause the
MIL
symbol to not light
directly when the fault occurs but first somewhat later.
According to legal regulations, the lamp must remain
alight for a period after the fault has been corrected.
