Glow plug pre-heat indicator
With the key in the ON position,
the
light will illuminate if
glow plug heat is necessary as a
starting aid. Wait until the light goes
off before starting. The light should always illuminate briefly, when the
ignition key is in the ON position. If the light does not illuminate, there
may be a problem. Refer toCold weather startingin theDriving
chapter of this supplement. After the engine starts, the light should
remain off. The light should always illuminate at least momentarily when
the engine is cold and the ignition is turned to ON. If it does not
illuminate, the glow plug system should be checked and repaired
promptly to avoid difficulty in cold starting.
Waterinfuel
During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to START (as part
of the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
Type A
Type B
Type C
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 toDraining the FCM/HFCM and changing the fuel filtersin the
Maintenance and Specificationschapter 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.
Engine air filter (if equipped)
The engine air filter warning light illuminates when the air filter
restriction gauge reaches the CHANGE FILTER mark.
Type A
Type B
The condition should be verified by inspecting the underhood air filter
restriction gauge; the warning light is only a secondary indicator. Always
use the underhood air filter restriction gauge to determine when the air
filter element needs to be changed.
The vehicle may be driven with the engine air filter warning light
illuminated/or when the underhood air filter restriction gauge has moved
to the CHANGE FILTER mark for up to 250 miles (400 km) without
damaging the engine or related components. However, the air filter
element must be replaced at the earliest opportunity. Refer toAir filter
restriction gauge (if equipped)in this chapter for more information.
