12.1.2 Water temperature gauge
Indicates the temperature of the engine
coolant.
▪ This gauge functions with the key switch
on and displays the coolant water tem
perature from left to right in a 10stage
gradation scale (In normal condition, the
final two stages on the far right do not il
luminate).
▪ The operator will be notified when the
water temperature is abnormally high as
the entire gauge starts blinking. At that
time, engine output will be limited to pre
vent engine overheat.
▪ Temporary overheating may be caused
by coolant leakage, low engine coolant
level, loosen fan belt, or other problem in
the cooling system. Ask the Toyota
dealer for an inspection.
CAUTION
•
Once the entire gauge blinks, discontinue the operation in progress and park the truck in
a safe location, apply parking brake and remove the key. Then, ask the Toyota dealer for
an inspection.
12.1.3 Hour meter
The hour meter operates when the key
switch is turned on.
It indicates the total number of truck operat
ing hours.
The digit on the far right displays in 1/10 of
an hour.
When the truck operating hour reaches
62500 hours, the meter will display "FULL".
Use this meter for the timing of periodic
maintenance and recording the operating
hours.
When an abnormality occurs to the truck
(diagnosis indicator lamp illuminates or
blinks) the error code and hour meter will be
alternately displayed.
CAUTION
•
Should an error code be displayed, park the truck in a safe location, apply parking brake,
remove the key and ask the Toyota dealer for an inspection.
•
When the timing belt is used over 4000 hours, the hour meter displays "bELT" for 10
seconds and the diagnosis indicator lamp illuminates after the key switch is turned on.
(Diesel engine models) Once "bELT" is displayed, have the timing belt replaced by the
Toyota dealer immediately. Failure to do so could cause serious damage to the engine.
Refer to Timing belt caution function section of this chapter for details.
12.1.4 Sedimenter/ fuel filter warning
(Diesel engine models)
The sedimenter is a device for separating
water from the fuel.
The fuel filter is a device for separating for
eign material from the fuel.
▪ The sedimenter/ fuel filter warning lamp
comes on to indicate that water in the
sedimenter exceeds the predetermined
level while the engine is running or the
negative pressure of the fuel filter
reaches the predetermined pressure
while the engine is running.
▪ If normal, the warning lamp comes on
when the key switch is turned on and
goes off when the engine starts.
▪ If the warning lamp comes on while the
engine is running, drain the water from
the sedimenter immediately. (See the
OPERATOR MAINTENANCE chapter of
this manual for the draining method.)
▪ If the warning lamp continues to illumin
ate while the engine is running, ask the
Toyota dealer for an inspection.
CAUTION
Continued operation with warning on may cause damage to the supply pump.
