NOTE
Provided the vehicle is parked on level ground,
an automatic nozzle will automatically shut off
when the fuel tank is approximately 95% full.
WARNING
DEF – Do not overfill
If an automatic nozzle is used for filling diesel
exhaust fluid (DEF), do not add further DEF
after the nozzle has automatically shut off flow
a first time.
If such nozzle is not available, use the DEF
level gage on the instrument panel to control
the quantity during filling.
Diesel exhaust fluid DEF will begin to crystallize
and freeze at 12°F (-11°C) and expand by 7%
when frozen. To allow expansion without
damaging the DEF tank, do not fill the tank with
more than 16 gallons (60 liters).
WARNING
Do not fill to more than 95% of the fuel tank
capacity. Do not "top off" the tank, doing so may
result in fuel spillage when the fuel expands.
