ACTUATION AREA
The entry function and start function
are available to use when a registered
key is in the actuation area.
1. Entry function actuation area— About
1 m (3 ft.) from each outside front
door handle and the trunk opener
switch
Only the door handle of the actuation
area that the key holder is in can be
operated.
If the key is close to the door handle,
windows or the center of the rear
bumper, on the ground or above the
roof, the entry function may not be
activated. 2. Start function actuation area—

The start function may not be acti-
vated, if the key is in the auxiliary box
of the driver ’s side instrument panel
and glove box, on the instrument pan-
el, on the package tray, on the floor,
etc.
In the following cases, the smart key
system may not operate properly.
When facilities issuing strong electro-
magnetic waves such as TV towers,
electric power stations, broad casting
stations are nearby.
In places where automated payment fa-
cilities are installed (such as gas sta-
tions).
When you are carrying a electronic key
together with a mobile communications
system such as a two −way radio or
cellular phone.
When the electronic key is in contact
with or covered by a metallic object.

When the electronic key is near a
high−voltage or noise −emitting device.
When you are carrying an electronic
key together with a key for another
smart key system equipped vehicle or
another instrument emitting radio
waves.
Depending on the position of the key
or vehicle body shape, the key may
not work well even within the actuation
area.
When the key surface is covered by a
sticker, etc. that may cut off electro-
magnetic wave.
Even if the smart key system does not
operate properly, you can still enter and
start the hybrid system. For further infor-
mation, see “Side doors” on page 38 and
“Trunk lid” on page 47 in this Section, and

STARTING THE HYBRID SYSTEM WHEN
THE ELECTRONIC KEY BATTERY IS
DISCHARGED
If the key indicator does not flash and
the hybrid system cannot be started by
using the start function, the battery
may be discharged. Replace the key
battery as soon as possible. (See
“—Replacing battery” on page 30 in
this Section.)
However the hybrid system can be turned
on in the following procedures.
1. While the brake pedal is depressed, touch the Toyota logo side of the
electronic key to the “POWER” switch. 2. Start the hybrid system within 5
seconds after the green indicator light
on the “POWER” switch comes on and
a buzzer sounds.
BATTERY POWER SAVING
Both the vehicle and key transmitters are
always sending signals to each other. To
prevent battery drain, the smart key sys-
tem is automatically deactivated in the fol-
lowing conditions:
If the electronic key is left outside of
the vehicle and within the effective
range of the entry function actuation
area for more than 10 minutes.
If the door lock or unlock operation is
not performed more than 2 weeks.
The key and the vehicle are communicat-
ing even while the vehicle is not being
driven. Do not leave the key near the
vehicle (within 2 m [7 ft.]).
The vehicle battery may drain if the
vehicle is not used for a long period of
time. To prevent battery drain, disconnect
the battery negative ( −) terminal or disable
the smart key system. (For details about
disable the smart key system, see
“DISABLING THE SMART KEY SYSTEM”
in this Section.)
