*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
*2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/her
as an adult depending on his/her physique or posture.
*3: Never install a rear −facing child restraint system on the front passenger seat. A forward− facing child restraint system should only
be installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 86 as for installing the child restraint
system.)
*4: When the front passenger does not wear a seat belt.

(a) Brake System Warning Lights andBuzzer
These lights come on in the following
cases when the “IG −ON” mode is enabled.
RED WARNING LIGHT
When the parking brake is applied...
This light comes on when the “IG −ON”
mode is enabled, even after the parking
brake is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
YELLOW WARNING LIGHT
When the regenerative brake system
is fails...
RED OR YELLOW WARNING LIGHT
When the hydraulic brake system
fails...
When the yellow warning light comes on,
it is no problem to continue driving. How-
ever, if the red warning light comes on,
it indicates a serious problem and you can
continue driving no longer. Have your vehicle checked at your
Toyota dealer in the following cases:
The lights do not come on even if the
parking brake is applied when the
“READY” light is on.
The lights do not come on even if the
“POWER” switch is pressed with the
parking brake released.
A red warning light turning on briefly dur-
ing operation does not indicate a problem.
CAUTION
If any of the following conditions oc-
curs, immediately stop your vehicle at
a safe place and contact your Toyota
dealer.
The red warning light does not turn
off even after the parking brake is
released while the hybrid system is
running.
The red warning light comes on or
buzzer sounds continuously.
In either case, this can indicate that
the brakes may not work properly and
your stopping distance will become
longer. Depress the brake pedal firmly
and bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
and “VSC” warning light.
In this case, not only the antilock
brake system and vehicle stability
control system will fail but also the
vehicle will become extremely unsta-
ble during braking.
In the following case, drive directly to
the nearest Toyota dealer.
The yellow warning light comes on
while driving.

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 turn off after
the “READY” light comes on.
There may be the case that the yellow
brake system, “ABS” and “VSC” warning
lights stay on for about 60 seconds after
the hybrid system is started. 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.

Connecting point
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
9. Charge the discharged battery with the jumper cables connected for approxi-
mately 5 minutes. At this time, run the
engine in the vehicle with the booster
battery at about 2000 rpm with the ac-
celerator pedal lightly depressed. 10. Start the hybrid system. Make sure the
“READY” light is on. If the hybrid bat-
tery warning light comes on in the mul-
ti−information display, the hybrid battery
is also discharged. Contact your Toyota
dealer.
11. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
12. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
13. If removed, replace all the battery vent plugs.
If the cause of your 12 volt battery dis-
charging is not apparent (for example,
lights left on), you should have it checked
at your Toyota dealer.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your hybrid
system in the normal way.
If the another attempt is not successful,
the battery may be depleted. Have it
checked at your Toyota dealer.
