For manual transmissions, fully depress the
clutch pedal, put the transmission in neutral, then
release the pedal.
If the vehicle has a two-pedal automated trans-
mission, shift it into gear, then back to neutral.
IMPORTANT: The driver must remain with the
vehicle during the entire regen cycle.

Press and hold the regen switch for 4 seconds.
The engine will increase rpm and initiate the
regen process.

After the parked regen has run for 20 to 40 min-
utes, the regen cycle is completed. The engine
idle speed will drop to normal, and the vehicle
may be driven normally. The HEST lamp may be
illuminated, but will go out when the vehicle
speed exceeds 5 mph (8 km/h), or the system
has cooled to normal operating temperature.
5.
To stop a parked regen at any time during the
process, engage the clutch, brake, or throttle
pedal, or turn off the engine.
DPF Maintenance
Eventually ash will accumulate in the DPF and the
filter will require servicing. DPF servicing must be
performed by an authorized technician, following the
engine manufacturer’s instructions. A record must be
maintained for warranty purposes, that includes:
•
date of cleaning or replacement;
•
vehicle mileage;
•
particulate filter part number and serial number.
