INFORMATION
When changing the mode, be sure
to push both “ ” (lock) and “ ”
(panic) buttons firmly, or panic
alarm may be activated.
 This operation will not change the
wireless remote control unlocking
function.
 In the single or driver’s door un-
locking mode, if you get into the
vehicle from the driver’s door carry-
ing the smart key, all the smart un-
locking controls activated by the
smart key will be stopped for secu-
rity. If you get out of the vehicle
from the driver’s door carrying the
smart key and get out of the effec-
tive range of the smart function,
unlocking control by the smart key
will be possible. However, unlocking
control may not be carried out for
5 seconds after you get out from
the vehicle. In this case, operate
unlock control again after 5 sec-
onds.
BATTERY POWER SAVING
When doors are locked, the smart entry
and start system transmits electromagnetic
waves to the outside of the vehicle at
regular intervals. For this reason, the ve-
hicle battery will be discharged if the ve-
hicle is left for a long time. If the key is
left within the effective range of the smart
function outside of the vehicle, the key
and the vehicle transmit electromagnetic
waves periodically. If these conditions con-
tinue for a long time, the battery in the
key and vehicle will be discharged.
To prevent the batteries from being dis-
charged, the smart function is automatical-
ly deactivated in the following conditions:
If there is no response from the key
for more than 14 days
If the key is left within the effective
range of the smart function outside of
the vehicle for more than 10 minutes To reactivate the smart function, perform
any of the following:
(a) Press the lock button on the outside front door handle or back door while
carrying the smart key.
(b) Perform a wireless remote control op- eration.
(c) Insert and turn the mechanical key in the keyhole of the driver’s door.

Without depressing the brake pedal
Carrying a smart key allows you to op-
erate the “POWER” switch without the
key being inserted into the key slot.
Each time you press the “POWER”
switch briefly without the brake pedal
depressed, the hybrid system mode
changes in the order of “OFF”, “ACC”,
“IGON” and then back to “OFF”.
The smart function can be set to become
inoperative using the smart cancel switch.
For details, see “Deactivating the smart
function” on page 32. 1) “ACC” (Green indicator is turned on)
Accessories such as the radio operate.
Pressing the “POWER” switch briefly with-
out depressing the brake pedal in the
“OFF” mode turns on this mode.
In the “ACC” mode, pressing the “POW-
ER” switch briefly while depressing the
brake pedal will start the hybrid system.
If you leave your vehicle in the “ACC”
mode for about an hour, the hybrid system
is automatically turned off.
2) “IGON” (Amber indicator is turned
on)
All accessories are operable.
Pressing the “POWER” switch briefly with-
out depressing the brake pedal in the
“ACC” mode turns on this mode.
In the “IG
−ON” mode, pressing the “POW-
ER” switch briefly while depressing the
brake pedal will start the hybrid system.

You may hear a motor sound in the en-
gine compartment when the brake pedal is
depressed with the hybrid system off.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid vehicle battery in the lug-
gage compartment. However, this does not
indicate any trouble.
If there is a problem somewhere in the
hybrid system, the hybrid system malfunc-
tion warning light will come on in place of
the “READY” light. If this happens, contact
your Toyota dealer.
CAUTION
Never start the hybrid system from
outside the vehicle, or an accident
may occur. Be sure to sit on the driv-
er seat, then start the system when
driving.
NOTICE
The hybrid system cannot be
started when the shift position is
“N”. Be sure to put it in “P” and
then start the system.
 If any warning light comes on (See
page 117 for details.) or the auxilia-
ry battery is disconnected, the hy-
brid system may not start by push-
ing the “POWER” switch. In that
case, push it once again. If the
“READY” light does not come on,
contact your Toyota dealer.
 When you start the hybrid system
at a lowered outside temperature, it
may take longer before the blinking
“READY” light changes to stay on.

Normal starting procedure

pedal depressed. The “READY” light starts
blinking. After a few seconds, the blinking
“READY” light remains on and a beep

tions, it may take time until the “READY”
light is on.)
The engine may not start even with the
“READY” light on.
