WAIT TO START
With the key in the ON position, the
WAIT TO START 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 to the
Starting
chapter in this guide. 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.
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 WATER IN FUEL light will illuminate when the
ignition is turned to START (as part of the light function check) and
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 filter bowl.
Refer to the
General maintenance
chapter for 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.
