Preheating indicator lamp
(2Z engine models)
Indicates preheating of the intake heater.
1. When the ignition switch is turned ON,
the lamp comes on and preheating starts.
The lamp goes off automatically when
preheating is complete. The engine will
start easily.
When the engine coolant temperature exceeds
2.5ºC, this lamp does not come on because pre-
heating is not carried out.
2. The length of preheating time is automati-
cally controlled according to the engine
coolant temperature. It gets somewhat lon-
ger when the engine coolant temperature
is low or in a cold season.
If the indicator lamp does not go off if it
comes on during engine running, the pre-
heating intake heater may be defective.
Please ask a Toyota dealer for inspection and
repair.
Engine oil pressure warning lamp
Comes on to indicate low engine oil pressure
while the engine is running.
1. If normal, the lamp comes on when the
ignition switch is turned to ON and goes
off when the engine starts.
2. If the lamp comes on while the engine is
running, either the engine oil is low or the
lubrication system is faulty. Stop the oper-
ation immediately and ask a Toyota dealer
for inspection and repair.
The “engine oil pressure warning lamp” does
not indicate the oil level. Check the oil level
using the oil level gauge before starting work.
Charge warning lamp
1. This lamp comes on to indicate an abnor-
mality in the charging system while the
engine is running.
2. If normal, the lamp comes on when the
ignition switch is turned to ON and goes
off when the engine starts.
• If the lamp comes on while the engine is
running, stop immediately, park the vehi-
cle in a safe location, stop the engine and
after the engine has cooled down inspect
the fan belt for cuts or looseness, adjust
it, and restart the engine.
• If lamp does not go off, the electrical system
may be faulty.Please ask a Toyota dealer
immediately for inspection and repair.
HST oil temperature warning lamp
While the engine is running, if the HST
(Hydraulic Static Transmission) hydraulic oil
temperature rises, the warning lamp comes on
to warn the operator.
In normal conditions, the lamp comes on when
the ignition switch is turned ON and goes off
when the engine starts.
• If the warning lamp should come on while
the engine is running, stop driving and
run the engine at a speed slightly faster
than idling speed, and allow the hydraulic
oil to cool until the lamp goes off.
•
If the hydraulic oil temperature reaches
85°C while performing material handling
and attachment operations or while travel-
ing, the heat protection function will activate
a warning buzzer to warn the operator.
Additionally, on vehicles with Australian
specifications, if the hydraulic oil temper-
ature reaches 100°C while performing
material handling and attachment opera-
tions or while traveling, the material han-
dling operation will stop.
If the warning buzzer should sound, stop
driving and run the engine at a speed
slightly faster than idling speed, and
allow the hydraulic oil to cool.
