Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record
some or all of the following information: Gasoline engine speed
 Whether the brake pedal was applied or not
 Vehicle speed
 To what extent the accelerator pedal was depressed
 Position of the transmission selector lever
 Whether the driver and front passenger wore the seat
belts or not
 Driver ’s seat position
 Front passenger ’s occupant classification
SRS airbag deployment data
 SRS airbag system diagnostic data
The Electronic Control Unit (ECU) of the electronically
controlled brake (ECB) may contain another EDR. There
are a variety of driving situations which include activating
the ECB under which the ECB EDR will record certain
information. The ECB EDR may record some or all of the
following information:
 Behavior of the vehicle
 Steering wheel angle
 Vehicle speed
 To what extent the accelerator pedal was depressed
 To what extent the brake pedal was applied
 To what extent the ECU controlled the condition of
the 4 wheels
 Vehicle stability control diagnostic data

CAUTION
Pull your vehicle off the road, put
the transmission in the “P” posi-
tion, apply the parking brake, turn
the hybrid system off and remove
the key.
In order to avoid personal injuries,
do not touch high voltage wiring,
connectors or high voltage parts
(inverter unit, hybrid battery and
etc.).
If exposed electric wires are pro-
truding inside or outside of your
vehicle, an electric shock may oc-
cur. Never touch the electric wires.
If fluid leaks or gets into some
parts of the vehicle, never touch it
because it may be strong alkaline
electrolyte from the hybrid battery.
If it contacts your skin or eyes,
wash it off immediately with a large
amount of water or if possible, bo-
ric acid solution. Get immediate
medical attention in order to help
avoid serious injury.
If a fire occurs in the hybrid ve-
hicle, leave the vehicle as soon as
possible. Never use a fire extin-
guisher that is not meant for elec-
tric fires. Using a small amount of
water may be also dangerous.
If your vehicle needs to be towed,
do it with the front wheels raised
(front wheel drive models) or all
four wheels raised (all models). If
the wheels with the traction motor
are on the ground when towing, the
motor may continue to generate
electricity. This may cause the elec-
tricity leakage. Depending on the
severity of the damage, electricity
leakage may cause fire. See “If your
vehicle needs to be towed” on page
353 in Section 4.
The emergency shut off system blocks
off the high voltage current and stops
the fuel pump to minimize the risk of
the electric leakage and the fuel leak-
age when a certain level of impact is
detected by the impact sensor. If the
system activates, your vehicle will not
restart. To restart the hybrid system,
contact a Toyota dealer.
CAUTION
Check to see if there are exposed
high voltage parts and cables. Nev-
er touch the parts and cables. See
“—High voltage components” on
page 6 in this Section for the loca-
tions of the high voltage parts and
cables.
Inspect the ground under the ve-
hicle. If you find that liquid has
leaked onto the ground, the fuel
system may have been damaged.
Leave the vehicle as soon as pos-
sible.

In the following case, drive directly to
the nearest Toyota dealer.
The yellow warning light comes on
while driving.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The red and yellow warning lights may
stay on for about 60 seconds after the
hybrid system is started. It is normal
if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red and yellow warn-
ing lights. It is normal if the light turns
off after a few seconds.
You may hear a small sound in the
engine compartment after the hybrid
system is started or the brake pedal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem turned off.
The brake pedal stroke may be short
when you turn the ignition key to the
“START” position with the brake pedal
depressed.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to the
“ON” position, the buzzer sounds for about
6 seconds and the reminder light flashes
if the driver ’s seat belt is not fastened.
Unless the driver fastens the belt, the
light continues flashing.
If the vehicle speed rises above 15 km/h
(9 mph) with the seat belt unfastened, the
buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 20 more seconds. Even if the vehicle
speed drops below 15 km/h (9 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. (c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the ignition key is turned to the
“ON” position, the reminder light flashes if
a passenger sits in the front passenger
seat and does not fasten the seat belt.
Unless the front passenger fastens the
belt, the light continues flashing.
If the vehicle speed rises above 15 km/h
(9 mph) with the seat belt unfastened, the
buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 20 more seconds. Even if the vehicle
speed drops below 15 km/h (9 mph), the
buzzer will continue to sound. To stop
the buzzer, fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built −in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash and buzzer to sound.
