294 Exhaust cleaning
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 AdBluenozzle and
AdBluesupply lines. The process takes about 90
seconds and during this time the ADRswitch 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 ADRswitch 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 MILsymbol 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.
Display message — with falling AdBlue level
To check for the amount of AdBlue in the tank, step to
the "Fuel Data" menu on the display and select "
AdBlue". It is an advantage to have this selected as a
favourite menu, see "Driver instructions, Display".
When there is only a small amount of AdBlue left in
the tank (approx 10%), the information lamp will light
and a message will be displayed to inform the driver
that it is time to top up with AdBlue.
If the AdBlue tank is empty, the following message is
shown on the display together with the information
Note!
It may be a punishable offence not to
use AdBlue or to try to interfere with
the exhaust cleaning system.
