The engine immobilizer system is a
theft prevention system using an elec-
tronic code. The transponder chip in
the key has an electronic code and
transmits the code to the vehicle. Only
when the electronic code in the chip
corresponds to the register ID code for
the vehicle, the engine immobilizer sys-
tem will be canceled and the engine
will start.
The engine immobilizer system is automat-
ically set when:
Vehicles with key cylinder−type ignition
switch—The key is removed from the igni-
tion switch.
Vehicles with smart key system—The igni-
tion switch is turned off.
The indicator light will start flashing to

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 the door handle,
windows and center of the rear bump-
er, the entry function may not be acti-
vated. 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.
When you are carrying an electronic
key together with a mobile communica-
tions system such as a two −way radio
or cellular phone.

IF KEY BATTERY DEAD
If the key indicator does not flash and
the engine cannot be started by using
the start function, the battery may be
dead. 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. With the brake pedal depressed, hold the electronic key close 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
The transmitters on the outside of the
vehicle and in the key transmit electro-
magnetic waves to each other while doors
are locked.
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 there is no response from the key
for more than 2 weeks.
To reactivate the smart key system, per-
form any of the following:
(a) Press the lock button on the outside front door handle or trunk opener
switch while carrying the electronic
key.
(b) Perform a wireless remote control op- eration.
(c) Insert and turn the mechanical key in the keyhole of the driver’s door. If the electronic key receives strong elec-
tromagnetic waves over a period of time,
the battery can be drastically run down.
You should always keep the at least 1 m
(3 ft.) away from the electronic key follow-
ing electrical appliances.

open or close. To stop the window part-
way, lightly move the switch in the oppo-
site direction and then release it.
If you push in the window lock switch on
the driver ’s door, the front passengers’

this function may work even if nothing is
caught. If the battery is disconnected or run
down,
the power window may not operate
automatically and the jam protection func-
tion will not function correctly after you
reconnect, replace or recharge the battery.

body to activate the jam protection
function intentionally.
The jam protection function may
not work if something gets caught
just before the window is fully
closed.
