Driving
NOTE: To prevent stationary regeneration, changing the driving conditions
gives the vehicle a better chance of conducting mobile regeneration. See
section 'Driving conditions for optimal DPF regenerations and fuel
consumption reduction'.
CAUTION: During the first regeneration of the DPF, the Emission
Aftertreatment System generates excessive smoke. This smoke
disappears after some time and does not return with the next
regenerations.
This smoke is not considered harmful.
Driving conditions for optimal DPF regenerations and fuel
consumption reduction
Additional fuel is used during regeneration, so optimal regeneration and therefore
reduction in fuel consumption are achieved during motorway driving.
Unfavourable driving conditions for regeneration are city driving and pick-up and
delivery: more fuel is needed for regeneration under these conditions. Regular
motorway driving is advised to achieve the optimal regeneration conditions and reduce
fuel consumption.
How to stop regeneration
DPF regeneration may cause high exhaust gas temperatures. If there is a risk of fire or
other hazardous situation, active DPF regeneration can be stopped or prevented by
using the DPF switch in the vehicle.
Since active regeneration can occur at any time, if fitted, the lower position ('OFF') of
the DPF switch can be pressed any time you drive into a hazard area where a
regeneration may be hazardous.
NOTE: Read the section 'Warning symbols on the master display' and
follow the instructions.
WARNING! Never allow regeneration to start automatically while
driving inside a building (a service bay or shop, for example). Any time
you plan to drive the vehicle into a hazard area where regeneration can
be dangerous, prevent regeneration from occurring by pressing the
'OFF' portion of the DPF switch. Hot exhaust gases produced during
regeneration can ignite an explosion, cause a fire or harm bystanders
and result in serious injuries.
