Adding Diesel Exhaust Fluid
The DEF low level message (located in the EVIC) will display when the DEF level is
low. Completely fill the DEF tank through the diesel exhaust fluid fill location
(located behind the fuel door) at every maintenance interval or before if prompted by
the Electronic Vehicle Information Center (EVIC).
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the amount of
DEF that is used in your vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it could be damaged.
Therefore, do not overfill the DEF tank. Extra care should be taken when filling
with portable containers to avoid overfilling. Note the level of the DEF gauge in
your instrument cluster. On pickup applications, you may safely add a maximum
of 2 gallons (7.5 liters) of DEF from portable containers when your DEF gauge is
reading ½ full.
DEF Fill Procedure
• Remove cap from DEF tank (located
behind the fuel door on drivers side of
the vehicle).
• Insert DEF container or fill nozzle into
DEF fill location and fill DEF tank.
• Reinstall cap onto DEF tank.
