Advanced Security Transmitter) is described as
Keyless Operation System (KOS).
The Keyless Operation System (KOS) enables the
driver to unlock all the doors*and the liftgate by just
pulling the front door outside handle or operating the
liftgate lock release handle, without taking the key out
from his/her pocket or bag when he/she is carrying a
Keyless Operation Key which has been registered in
the vehicle's KOS-ECU. KOS also allows the driver to
lock all the doors and the liftgate by pressing the lock
switch on the front door outside handle or on the
liftgate lock release handle (door entry function), and
start the engine without using the conventional
mechanical key (engine start function). KOS has the
following features:

｠

The keyless operation key incorporates the lock
and unlock switches on it. Like the conventional
keyless entry system, remote control operation can
be performed by using these switches. The keyless
operation key also incorporates an indicator light
that enables the driver to check if the signal is

transmitted correctly or if the battery in the key is
discharged.

｠

The keyless operation Key incorporates the
immobilizer function that inhibits starting the engine
by using an unauthorized key.

｠

The incorporated TPMS function monitors the air
pressure of all the tires.

｠

Each vehicle is provided with two keyless operation
keys. Up to four keyless operation keys can be
registered in the vehicle's KOS-ECU.

｠

The keyless operation key incorporates an
emergency key with a transponder to lock/unlock
the doors and start the engine in case the battery in
the keyless operation key is discharged or the
Keyless Operation System is not working normally.

｠

The driver can customize KOS; enabling/disabling
all the system functions, enabling the door locking/
unlocking function only, or enabling the engine
starting function only.

NOTE:

When the driver’s front door outside

handle is operated, only the driver’s door is
unlocked.
