Water in fuel (if equipped)
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to
remove water from the fuel. The
water in fuel indicator light illuminates when the fuel filter/water
separator has a significant quantity of water, or when the ignition key is
switched to the START position. If the light illuminates when the engine
is running, stop the vehicle as soon as safely possible, shut off the engine
and drain the filter bowl. Allowing water to stay in the system could
result in extensive damage to, or failure of, the fuel injection system.
To drain the fuel filter/water separator (refer toMaintenance and Care
section for procedure). Rotate the valve at the bottom of the filter
assembly allowing water to drain from the system. Close the valve upon
completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Check trans (Allison automatic transmission)
The lamp will illuminate for several
seconds after the ignition is turned
to the ON position. Illumination of
this light indicates that a problem
has been detected and shifting may
be restricted. Depending upon the
severity of the problem, the read-out digit on the shifter display may be
blank. Operation may continue in order or reach service assistance. The
ECU may not respond to shift selector requests, since operating
limitations are being placed on the transmission, i.e. upshifts and
downshifts may be restricted. Direction changes will not occur.
Refer to the Transnission Operator's Manual for more information.

GAUGES
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or after
refueling. The ignition should be in
the OFF position while the vehicle is
being refueled. When the gauge first
indicates empty, there is a small
amount of reserve fuel in the tank.
When refueling the vehicle from an empty indication, the amount of fuel
that can be added will be less than the advertised capacity due to the
reserve fuel.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
