1.

When KOS-ECU detects that the unlock sensor on
the  driver-side/front  passenger-side  door  outside
handle or the liftgate lock release handle (switch) is
turned  ON,  it  transmits  the  exterior  data  from  the
exterior  transmitter  antenna  assembly  on  the
operation  side.  At  the  same  time,  KOS-ECU
transmits the interfering radio wave* (reversal code)
from the exterior transmitter antenna assembly on
the  other  side  (The  interfering  radio  wave  will  be
transmitted from the front passenger-side antenna
assembly when the driver-side door outside handle
is operated, and vice versa. It will not be transmitted
when the liftgate lock release handle is operated).

NOTE: 

*: The interfering radio wave is

transmitted to disable the door lock operation
by a person without the keyless operation key

while a user with the keyless operation key is
operating the door lock from the opposite side
of the vehicle.

2.

After  the  exterior  data  are  transmitted  from  the
exterior transmitter antenna assembly, the interior
data  are  transmitted  from  the  interior  transmitter
antenna assembly (front).

3.

For  the  specified  time  period  (varies  with  the
number of the keyless operation keys registered in
KOS-ECU), KOS-ECU monitors the response from
the  keyless  operation  key  that  meets  the  unlock
conditions.

｠

When  the  keyless  operation  key  receives  the
exterior data only, KOS-ECU transmits the unlock
request  (request  to  unlock  the  applicable
position) to ETACS-ECU.

KEYLESS OPERATION SYSTEM (KOS)

SYSTEM OPERATION

｠

When  KOS-ECU  receives  no  response  that
enables  the  unlocking  after  the  specified  time
period  has  passed,  it  performs  the  retry  cycle
once  (When  no  response  after  the  retry,  KOS-
ECU terminates the unlocking operation).

UNLOCKING OPERATION INHIBITION TIME
If the customer pulls the door outer handle to make
sure  the  doors  are  locked,  unlocking  operation  is
inhibited  for  three  seconds  after  the  doors  and  the
liftgate are locked by the lock switches on the driver-
side/front passenger-side door outside handle or on
the liftgate lock release handle. This duration can be
selected from zero, three seconds, and five seconds,
and can be switched using a customization function.
(Refer  to P.42B-29.)  The  default  factory  setting  is
3 seconds.

UNLOCKING OPERATION INHIBITION
CONDITIONS
The door unlocking operation is inhibited when:

｠

The emergency key is in the ignition switch.

｠

The push switch in the steering lock is ON.

｠

During the unlocking operation inhibition time

LOCKING OPERATION OF DOOR ENTRY

FUNCTION

The  keyless  operation  key  and  KOS-ECU
communicate  to  certify  the  keyless  operation  key
when  the  lock  switch  on  the  driver-side/front
passenger-side door outside handle or on the liftgate
lock  release  handle  is  turned  ON.  When  KOS-ECU
certifies the registered keyless operation key only on
the outer side of the vehicle, it requests ETACS-ECU
to lock all the doors (including the liftgate).

2.

After  the  exterior  data  are  transmitted  from  the
exterior transmitter antenna assembly, the interior
data  are  transmitted  from  the  interior  transmitter
antenna assembly (front).

3.

After  the  specified  time  period  (varies  with  the
number of the keyless operation keys registered in
KOS-ECU)  has  passed,  confirm  that  there  is  no
keyless operation key in the interior.

｠

When KOS-ECU receives the response from the
keyless operation keys that received the interior
data,  KOS-ECU  cancels  without  the  locking
operation.

4.

The  interior  data  are  transmitted  from  the  interior
transmitter assembly (front).

5.

After  the  specified  time  period  (varies  with  the

｠

When all the responding keyless operation keys
receive  the  exterior  data  only,  KOS-ECU
transmits the lock request to ETACS-ECU.

｠

If there is no response from the keyless operation
keys, perform Step 6 once.

6.

KOS-ECU  transmits  the  exterior  data  from  the
exterior  transmitter  antenna  assembly  on  the
operation  side.  At  the  same  time,  KOS-ECU
transmits the interfering radio wave (reversal code)
from the exterior transmitter antenna assembly on
the other side. (The interfering radio wave will be
transmitted from the front passenger-side antenna
assembly when the driver-side door outside handle

7.

After  the  specified  time  period  (varies  with  the
number of the keyless operation keys registered in
KOS-ECU)  has  passed,  confirm  that  the  lock
conditions are met.

｠

When the responded keyless operation keys after
the  retry  receives  the  exterior  data  only,  KOS-
ECU transmits the lock request (request to lock
the actuated position) to ETACS-ECU.

LOCKING OPERATION INHIBITION CONDITIONS
In the following cases, the door locking operation is
inhibited.

｠

Any door or the liftgate is open/ajar (door switch is
ON). (including door ajar)

｠

The emergency key is in the ignition switch.

｠

The push switch in the steering lock is ON.

AUTO LOCK FUNCTION

The auto lock function locks the doors automatically
when a driver carrying the keyless operation key left
the car with all the doors closed and unlocked. This
function  prevents  the  doors  from  being  unlocked
accidentally. Using a customization function, the auto
lock function can be selected between "Auto lock" and
"No  auto  lock".  (Refer  to P.42B-29.)  The  initial
setting is "No auto lock".
