(d) Charging System Warning Light
This warning light comes on when the
engine switch is turned to the "ON" posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while the engine is running, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have

(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(f) Low Engine Oil Level Warning Light
(diesel−powered vehicles)
This light indicates that the engine oil le-
vel needs to be checked. If the light
comes on while you are driving on rough
roads or steep inclines, take your vehicle
to a level spot to see whether the light
goes off. If it remains on, check the oil
level following the instructions of "Check-
ing the engine oil level" on page 312 in
Section 7−2.
While driving on steep inclines or rough
roads which causes the vehicle to sub-
stantially sway or on curves, this light
may come on due to the movement of
engine oil in the engine.
In normal conditions, due to engine oil
consumption, this light may come on earli-
er than the specified service interval of
the scheduled maintenance. This is be-
cause the engine oil is consumed to the
low level within the scheduled mainte-
nance interval and does not indicate a
problem. (For detailed information, see
"Facts about engine oil consumption" on
page 236 in Section 2.)
NOTICE
Continued engine operation with low
engine oil will damage the engine.
