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 276.
(e) 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 “Please
press “P” to engage Park.” and “The bat-
teries will not be charged if the transaxle
is in Neutral N.” appears on the multi −in-
formation display. (See “Service reminder
indicators and warning buzzers— —Multi −
information display” on page 124 or “Pre-
cautions for use” on page 14 or “Fuel
gauge” on page 114 for instructions.) (f) “ABS” Warning Light
The light comes on when the “IG
−ON”
mode is enabled. If the anti −lock brake
system and the brake assist system work
properly, the light turns off after the
“READY” light comes on. Thereafter 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
but the brake assist system still operates.
In this case, 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
“IG −ON” mode is enabled, or the light
remains on after the “READY” light
comes 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 red brake system
warning light, immediately stop your
vehicle 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 hybrid system is
started. It is normal if it turns off after
a whi l e.

122
Depressing the brake pedal repeatedly
may turn on the light. It is normal if
it turns off after a few seconds.
(g) SRS Warning Light
This light will come on when the “IG
ON” mode is enabled. After about 6
seconds, the light will go off. This
means the system of the airbag and
front seat belt pretensioners are operat-
ing properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, warning light, interconnecting
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
“IG −ON” mode is enabled or remains
on for more than 6 seconds.
The light comes on while driving. (h) Open Door Warning Light
This light remains on until all the doors
are completely closed.
(i) 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 following
case:
All the segments blink.
(j) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the “IG −ON”
mode is enabled, and will go off after
about a few seconds. When you drive for about 7200 km (4500
miles) after engine oil replacement, this
light illuminates for about 3 seconds and
then flashes for about 12 seconds when
the hybrid system is in the “IG
−ON”
mode. If you continue driving without en-
gine oil replacement, and if the driving
range exceeds 8000 km (5000 miles), the
light will come on after the “IG −ON” mode
is enabled. The light will remain on there-
after.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace the oil as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Press the “POWER” switch to the “OFF” mode
with the odometer reading
shown. (For details, see “Odometer and
two trip meters” on page 115.)
2. Press the “POWER” switch twice to select the “IG −ON” mode while holding
down the trip meter reset button.

123
Hold down the button for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
remain flashing.
(k) “VSC” warning light
This light warns that there is a problem
somewhere in the vehicle stability control
system.
The light will come on when the “IG−ON”
mode is enabled and will go off after the
“READY” light comes on.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the “IG −ON” mode is enabled.
The warning light remains on after the
“READY” light comes on.
The warning light comes on while you
are driving.
CAUTION
If the “VSC” warning light remains on
together with the red brake system
warning light, immediately stop your
vehicle at a safe place and contact
your Toyota dealer.
In this case, not only the vehicle sta-
bility control system will fail but also
the vehicle will become extremely un-
stable during braking.
(l) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key if you open the driver’s door when
the hybrid system is off and the key is
inserted into the key slot.
(m) Shift Position Reminder Buzzer
This buzzer will sound if the driver ’s door
is opened while the hybrid transaxle is in
“N”, “D” or “B”. CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level indica-
tor light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Press the “POWER” switch twice with- out pressing the brake pedal to select
the “IG −ON” mode. At this time, all the
bulbs are checked in self −diagnosis
mode.
All the service reminder indicators ex-
cept the open door warning light come
on. The yellow brake system, “ABS”
and “VSC” warning lights go off after
a few seconds.
There may be the case that the yellow
brake system, “ABS” and “VSC” warning
lights stay on for about 60 seconds after
the “IG −ON” mode is enabled. It is normal
if they go out after a while.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.
