During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator illuminates
when the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 187).

after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.

separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
