addition to the MIL lamp and CHECK engine lamp
(on vehicles with a Cummins ISB or ISC/L engine).
If the DEF is not refilled, a 5 mph (8 km/h) speed
limit is applied after the next engine shutdown, while
parked and idling, or if a fuel refill is detected.
DEF Contamination or SCR Tampering
NOTICE
Once contaminated DEF or tampering has been
detected, the vehicle must be taken to an autho-
rized service facility to check the SCR system for
damage and to deactivate the warning lights and
engine limits.
If contaminated DEF or tampering with the ATS is
detected, the DEF warning light flashes and the MIL
lamp illuminates to warn the driver. The CHECK en-
gine lamp also illuminates on vehicles with a Cum-
mins ISB or ISC/L engine.
