er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.
Do not fill a fuel container on a
plastic truck bed liner, a rubber
truck bed mat, or any other insulat-
ing material. A static electricity
charge could cause a spark and fire
hazard. The proper procedure is to
place an approved fuel container on

The gauge indicates the approximate
quantity of the fuel remaining in the
tank when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a nonreturn type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
