Warnings
The SCR system continuously
monitors emissions reduction
performance and SCR system
malfunction (Type A or Type B).
When a malfunction or incorrect
fluid (such as water or low
concentrated DEF, etc.) is detected,
the SCR system will turn on warning
and indicator lights to encourage
you to have the condition corrected.
In the case of incorrect fluid or if an
SCR system malfunction (Type A) is
detected, continuing to drive for too
long after these lights come on may
eventually result in a severe vehicle
speed limitation.
The following is a summary of the
warning lights, indicator lights and
restrictions. When these warning
and indicator lights come on the
DIC, promptly have the vehicle
inspected and serviced at a dealer.
In the case of SCR system
malfunction (Type B), have the
vehicle inspected and serviced at a
dealer.
