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 reminds you to remove the
key if you open the driver’s door when the
hybrid system is off and the key is in-
serted 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.

(a) Discharge Warning Light
This light warns that the auxiliary battery
is being discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The hybrid system will continue to oper-
ate, however, until the auxiliary battery is
discharged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.(b) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it 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 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.
(c) High Coolant Temperature Warning Light
The light operates to warn that the hybrid
system is almost over heating.
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 242.
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.
Continued driving with the light on
could result in the overheating of
hybrid system.
