WARNING
Never idle your vehicle for prolonged
periods
of time if you sense that ex-
haust fumes are entering the cab. In-
vestigate the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions, drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
CAUTION
DO NOT idle the engine for excessive-
ly
long periods. Long periods of idling,
more than 10 minutes, can cause poor
engine performance.
1. Using the Scroll Wheel, target the
number of minutes and press
Select.
2. Back to return to the Settings
menu.
Engine Aftertreatment System
This vehicle has an Engine Aftertreatment
System (EAS), to control vehicle exhaust
emissions.
The Engine Aftertreatment
system consist of a Diesel Particulate Filter
(DPF), Selective Catalyst Reduction
(SCR), DPF Switch and warning lights. The
DPF will trap soot from the engine exhaust
gases. The SCR uses Diesel Exhaust Fluid
to reduce the levels of NOx in the engine
exhaust. The EAS will periodically clean
(regenerate) the DPF.
Your vehicle may be equipped with an
additional feature designed to alert a
remote operator that the aftertreatment
system requires a regeneration. When the
EAS detects a heavily loaded DPF it will
sound the city horn for 10 seconds while
continuously flashing the vehicle
headlamps. The operator can resolve and
reset the alert by performing a parked
regeneration. Alternatively
, the notification
can be dismissed by pressing the clutch or
the service brake. Dismissing the alert
does not reset it, the next alert will occur at
the next higher soot level if a parked
regeneration is never performed.
