24p001a
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly full–Indicator at “F”
Nearly empty–Indicator at “E”
It is a good idea to keep the tank over
1/4 full.
When you refuel on the slope, the indica-
tor may not show the correct level.
When you refuel less than about 11.4 L
(3.0 gal., 2.5 lmp. gal.), the fuel indicator
may not change.
After the auxiliary battery is reconnected,
one segment will flash for a while.Depending on the ambient temperature,
the fuel quantity is less than 45 L (11.9
gal., 9.9 lmp. gal.) even at “F”. However,
this does not affect the fuel consumption
and the remaining fuel ratio indicated on
the gauge. (For details, see “Fuel” on
page 146 in Section 3.)
24p002a
Blink
Low fuel level indicator light
If the fuel level approaches “E” or the low
fuel level indicator light blinks, fill the fuel
tank as soon as possible.

At the first blinking of the light, the master
warning light in the instrument cluster
comes on and the message appears on
the multi−information display to remind the
driver to fill fuel.
24p010a
The fuel system malfunctions in the fol-
lowing cases, so contact your Toyota
dealer.
All the segments blink.
The “E” mark and the segments indi-
cating remaining fuel blink.

High coolant temperature
warning light in red
Low coolant temperature
indicator light in blue
The indicator and warning lights indi-
cate the coolant temperature when the
ignition switch is on. The hybrid sys-
tem operating temperature will vary
with changes in weather and hybrid
system load.
The red high coolant temperature warning
light will come on when the ignition key
is turned to the “ON” position. After a few
seconds, the light will go off.
If your coolant temperature is cool with
the ignition switch on, the blue low cool-
ant temperature indicator light comes on.
If it keeps lighting on with the hybrid sys-
tem fully warmed, contact your Toyota
dealer as soon as possible to service the
vehicle.

If the red high coolant temperature warn-
ing light comes on, your hybrid system is
too hot. If your vehicle overheats, stop
your vehicle and allow the hybrid system
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.
NOTICE
Do not remove the thermostat in
the cooling system as this may
cause the hybrid system to over-
heat. The thermostat is designed to
control the flow of coolant to keep
the temperature of the hybrid sys-
tem within the specified operating
range.
 Do not continue driving with an
overheated hybrid system. See “If
your vehicle overheats” on page
172 in Section 5.
24p004d
This meter displays the odometer and
two trip meters.
1. Odometer—Shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.
3. Trip meter reset button—Resets the two trip meters to zero, and also
change the meter display. To change the meter display, quickly
push and release the button. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the button until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.

(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following:
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
This case is a temporary malfunction. The
malfunction indicator lamp will go off after
taking several driving trips.
If the lamp will not go off even after
several trips, contact your Toyota deal-
er as soon as possible.
There is a problem somewhere in the
hybrid system or warning light system
itself.
Contact your Toyota dealer as soon as
possible to service the vehicle. Emissions inspection and maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (On
−Board Diag-
nostics) system before taking your vehicle
for the inspection.
