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 igni-
tions switch is turned on and goes off when the
engine starts.
2. If the lamp comes on while the engine is run-
ning, either the engine oil is insufficient or the
lubrication system is faulty. Stop the operation
immediately and ask a Toyota dealer for inspec-
tion and repair.
Note: The "engine oil pressure warning lamp"
does not indicate the oil level. Check the oil level
using the oil level gauge before starting work.
Sedimenter warning lamp
(Diesel models)
The sedimenter is a device for separating water
from the fuel.
1. The warning lamp comes on to indicate wa-
ter in the sedimenter exceeds the predetermined
level while the engine is running.
2. If normal, the lamp comes on when the igni-
tions switch is turned on and goes off when the
engine starts.
Note: If the OK monitor is provided, the lamp
does not come on when the ignition switch is
turned on. It functions the same way as the OK
monitor.
3. If the lamp comes on while the engine is run-
ning, drain water immediately. (See the self serv-
ice section for the draining method.)
Caution
Continued operation with the lamp on may
cause seizure of the injection pump and pump
damage.
Preheating indicator lamp
(Diesel engine models: standard in
designated area)
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 com-
plete. The engine will start easily.
Note: When the engine coolant temperature ex-
ceeds 2.5°C, this lamp does not come on be-
cause preheating is not carried out.
2. The length of preheating time is automati-
cally controlled according to the engine coolant
temperature. It gets somewhat longer when the
engine coolant temperature is low or in a cold
season.
Caution
If the indicator lamp does not go off if it comes
on during engine running, the preheating in-
take heater may be defective. Please ask a
Toyota dealer for inspection and repair.
