When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or al-
low open flames when refueling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.
2. To remove the fuel tank cap, turnthe cap slowly counterclockwise,
then pause slightly before removing
it. After removing the cap, hang the
tether as shown in the illustration.
It is not unusual to hear a slight swoosh
when the cap is opened. When insta lling,
turn the cap clockwise till you hear a
click.
If the cap is not tightened securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
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.
CAUTION
Make sure the cap is tightened se-
curely to prevent fuel sp illage in
case of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It has a built
in check valve to reduce fuel tank
pressure.

The gauge indicates the approximate
quantity of the fuel remaining in the
tank when the ignition switch is on.
Nearly full—Indicator at “F”
Nearly empty—Indicator at “E”
It is a good idea to keep the tank over
1/4 full.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.If the fuel tank is full or the fuel quantity
has increased or decreased by more than
5 liters since the vehicle was turned off,
the position display is recalculated. If the
fuel quantity has increased or decreased
by less than 5 liters since the vehicle was
turned off, the previous position is dis-
played.
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.
If the fuel gauge display flashes or the
remaining quantity is not displayed after
the flashing, there may be a problem in
the system. In this case, contact your
Toyota dealer as soon as possible.The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves to the “H” position
and flashes, your engine is too hot. If
your vehicle overheats, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stopandgo traffic.

If the engine coolant temperature gauge
needle is not displayed, there may be a
problem in the system. In this case, con-
tact your Toyota dealer as soon as pos-
sible.
NOTICE
 Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your
vehicle overheats” in Section 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
2ZZGE engine only—The engine will not
exceed 7100 rpm before it warms up.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
