User Manual

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.

Cruise Control
WARNING
DO NOT operate the cruise control
when
operating on road surfaces with
poor traction (wet, icy, or snow cov-
ered roads) or in heavy traffic. Acceler-
ations caused by the normal operation
of the cruise control could cause you
to lose control of the vehicle resulting
in an injury accident.
Cruise control functions and features may
vary depending upon which engine you
have. For a specific explanation of your
cruise control, see the cruise control or
engine manual included with your vehicle.
This vehicle's electronic system will
perform a ‘rationality check’ every time the
vehicle is started. This check is to ensure
that the service brakes are working before
allowing cruise control to function. This
safety feature is designed to ensure that a
driver is able to cancel the cruise set speed
by using the service brake pedal. The
system will not allow cruise control
operation if it does not pass the ‘rationality
check.’ The display will prompt you to
press the service brake pedal if it has not
