Warning Level 1

Warning Level 1 is triggered when the ECM first detects an abnormal value on a reductant system circuit. The Driver Information Center (DIC) displays the following messages:

For Non-Emergency vehicles and Emergency vehicles MY 2013 and older:

• Service Exhaust Fluid System
• See Owner's Manual Now
• 160 km (99 miles) until 105 km/h (65 mph) Max Speed

For Emergency vehicles MY 2014 and newer:

• Service Exhaust Fluid System
• See Owner's Manual Now
• 999 km (620 miles) until 105 km/h (65 mph) Max Speed

The messages alternate every 5 seconds in the DIC until acknowledged by the driver; however, the mileage countdown message remains in the DIC. The DEF Indicator in the instrument panel is illuminated.
