(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.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 198
in Section 7.
(f) Master Warning Light
()
If the master warning light comes on, the
warning light for the faulty system is high-
lighted or the message such as “When
you park your car, make sure you shift to
Park P.” and “The batteries will not charge
if the shifter is in N” appears on the mul-
ti −information display. (See “Service re-
minder indicators and warning buzzers—
—Multi −information display” on page 97
in this section or “Precautions for use” on
page 12 in Section 1 −2 or “Fuel gauge”
on page 88 in Section 2− 4 for instruc-
tions.) (g) Output Control Warning Light
()
This light comes on when the ignition
switch is on. It goes off when the electric
motor is ready to run.
The warning light comes on when the hy-
brid vehicle battery temperature is low or
high, or the hybrid vehicle battery capacity
is decreased with the selector lever at “R”
during driving. If the light comes on, the
power will be limited. Drive your vehicle
without hard acceleration.
(h) 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.
(i) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system works properly, the
light turns off after a few seconds. There-
after if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts monitored by
the warning light system. Contact your
Toyota dealer as soon as possible so
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but does not indicate the mal-
function:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if
it turns off after a few seconds.
(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ACC” or
“ON” position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, warning light, in-
terconnecting wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turn to the “ACC” or
“ON” position or remains on.
The light comes on or flashes while
driving.

(k) Open Door Warning Light
This light remains on until all the doors
are completely closed.
(l) Low Fuel Level Indicator Light
This light blinks when the fuel level in the
tank becomes nearly empty. Fill up the
tank as soon as possible.
At the first blinking of the light, the mes-
sage appears on the display to remind the
driver to fill fuel.
Contact your Toyota dealer in the fol-
lowing cases:
All the segments blink.
The “E” mark and the segments indi-
cating remaining fuel blink.
(m) High Coolant Temperature Warning Light
The light operates to warn that the hybrid
system is almost over heating.
The light will come on when the ignition
key is turned to the “ON” position. After
a few seconds, the light will go off.
If it comes on while you are driving, stop
the vehicle and check your hybrid system.
For detailed instructions, see “If your ve-
hicle overheats” on page 172 in Section
5.
NOTICE
Continued driving with the light on
could result in the overheating of hy-
brid system.

return to the “ON” position when released.
Being different from ordinary vehicles, you
cannot start your vehicle with the running
mode selector lever in “N” position.
“ON”—The hybrid system starts to run
when the accelerator pedal is depressed
with the “READY” light and all accesso-
ries on.This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the hybrid system is off.
If you leave your key in the “ACC” posi-
tion for a while, put the running mode
selector lever in “P” position.
If you leave the key in the “ACC” or

Hybrid transaxle
Your hybrid transaxle has a shift lock sys-
tem to minimize the possibility of incorrect
operation. This means you can only shift
out of “P” position when the brake pedal
is depressed (with the ignition switch in
“ON” position and the lock release button
depressed).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.

When the cruise control is being used
even if you shift the selector lever to “B”
position, engine braking will not be applied
because the cruise control is not can-
celled. For ways to decrease the vehicle
speed, see “Cruise control” on page 107.
