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 door
handle and trunk opener switch.
If the key is close to a door handle,
a window, the center of the rear bump-
er, on the ground or above the roof,
the entry function may not operate
properly. 2. Start function actuation area—
Inside
of the cabin.
The start function may not be activated
if the key is on the instrument panel,
on the package tray, in the glove box
or on the floor, etc.
In the following cases, the smart key sys-
tem 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 an electronic
key together with a mobile communica-
tions 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 another person is operating a
wireless remote control function on
another vehicle near your vehicle.
When the battery is discharged. To re-
place the battery, see “—Replacing bat-
tery” on page 25 in this Section.
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.
If the smart key system does not oper-
ate properly and you cannot enter, you
can lock and unlock all the doors by
using mechanical key attached to the
master key or wireless remote control
function.

STARTING THE ENGINE WHEN THE
ELECTRONIC KEY BATTERY IS
DISCHARGED
If the key indicator does not flash and
the engine 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 25 in this Section.)However the engine can be started in the
following procedures.
1. While the brake pedal is depressed, touch the Toyota logo side of the
electronic key to the “ENGINE START
STOP” switch.
2. Start the engine within 5 seconds after the green indicator light on the
“ENGINE START STOP” 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 the batteries from being dis-
charged, the smart key system is auto-
matically deactivated in the following con-
ditions:
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”
on page 33 in this Section.)
If the battery is disconnected, the power
window and moon roof may not operate
automatically and the jam protection func-
tion will not function correctly after you
reconnect. In this case, you should
normalize each system. To normalize
them, see “Power windows” on page 41
and “Electric moon roof” on page 52 in
Section 1 −2.
