INSTRUCTIONS
If the vehicle runs out of DEF:
Vehicles that use DEF will have indicators on the dash that will alert the driver of the quantity of DEF on
board. A gauge similar to a fuel gauge will indicate the level of DEF.
There will be a DEF low level warning lamp that will illuminate when DEF is low.
If the vehicle would run completely out of DEF, vehicle power will be de-rated and speed will be reduced
to approximately 15 MPH. Once the tank has been refilled the engine will resume normal power levels.
