If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer to Draining the FCM/HFCM and changing the fuel filters in the
Maintenance and Specifications chapter of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
Do not drain the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.

use the underhood air filter restriction gauge to determine when the air
filter element needs to be changed.
