Water in fuel: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
light will illuminate when the fuel filter/water separator
has a significant quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the fuel
filter/water separator. Refer to your engine operator’s manual for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
WARNING:Do not drain water separator while engine is
running. Fuel may ignite if separator is drained while engine is
running or vehicle is moving.
Diesel exhaust fluid:Illuminates
when the diesel exhaust fluid level
falls below 0.5 gallon (1.9L) in the
5 gallon (19.0L) tank or 1 gallon
(3.8L) in the 9 gallon (34.0L) tank.
Refill the tank or, at a minimum,
add at least 1 gallon (3.8L) in the
5 gallon (19.0L) tank or 2 gallons
(7.6L) in the 9 gallon (34.0L) tank to turn off the light.

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 to 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 your transmission operator’s manual for more information.

Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the

when the engine is not running, or
in a position between on and start,
or by applying the parking brake
when the ignition is turned to the on position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after

light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
