ately. P. 1-9

lit, starts flashing.

lowing warning is issued and the driving perfor-
mance is restricted as follows:
• The DEF level warning lamp continues to
flash.

tor flash quickly (at 0.25-second intervals).

flashing.
• is in red.

ing the gear in 1st or reverse, so the vehicle can

2.5 Degraded DEF quality (warning pattern 4)
If the system detects a deterioration in quality of the
DEF due to addition of any fluid (water, low-density
DEF, etc.) other than acceptable DEF, the warning
lamps will light and flash, a buzzer will sound, and
the engine power will be automatically reduced.
If this condition happens, shut off the engine and
contact an authorized dealer to have the degraded
DEF drained and the vehicle inspected.
