1. Keyless access door unlock function check

(1) When carrying the access key with all doors locked by keyless lock operation, check that when the touch sensor (unlock) built in to the back side surface of door outer handle of front door is touched, the driver’s door will unlock (when touched on the driver’s side) or all doors will unlock (when touched on the passenger’s side) and the answer-back function operates (hazard light blinks twice, access buzzer sounds twice).

(2) In the keyless access door unlock detection area, hold the access key at the same height as the outer handle (approx. 80 cm from the ground) and in the direction shown in the figure, and check that the vehicle becomes unlock mode [access key LED (red) blinks] at 40 to 80 cm from the vehicle.

NOTE:

Check the access key battery if the LED (red) does not illuminates when the access key button is pressed. Access Key > INSPECTION">

2. Keyless access door lock function check

(1) When carrying the access key outside of the vehicle with all doors closed and unlocked, check that when the touch sensor (lock) on the surface of door outer handle of front door is touched, all doors will lock and the answer-back function operates (hazard light blinks once, access buzzer sounds once).

CAUTION:

If the access key is within the vehicle but not within the detection area (in the instrument panel, on the rear tray, in the glove box, on the floor, or in the door trim pocket), then lockout protection will not function when the doors are locked and the access key will be locked into the vehicle.

(2) To check the keyless access door lock operation range, hold the access key at a height of 10 cm under the bottom edge of the door glass (approx. 80 cm from the ground), point it in the direction shown in the figure at a distance of approx. 30 cm from the vehicle, and check that all doors lock and the answer-back function operates (hazard light blinks once, access buzzer sounds once) when you touch the touch sensor (lock).

(3) Check the passenger’s side door in the same manner.

NOTE:

• When the door cannot lock if the touch sensor (lock) is touched, touch the touch sensor (lock) with palm.

• Since communication is not possible within close range (20 cm or less) of the door outer handle, the access key may not operate if you touch the touch sensor (lock) with the same hand you are holding the access key.

• If the lockout prevention buzzer sounds, it is possible that the interior transmitter has radio wave leakage.

3. Check of the keyless access rear gate function

However, if the shift lever is a range other than the P range and the push button ignition switch is pressed from ignition ON, then the status does not change to ignition OFF and instead will change to ACC ON.

(3) After the vehicle has stopped, press the push button ignition switch and ignition is turned OFF (engine stopped • all power supplies OFF). However, if the shift lever is in any range except for the P range and the push button ignition switch is pressed with the vehicle stopped, then the ignition is not turned OFF and instead the power supplies changes to ACC ON. Check that the steering lock operates if the door is opened in the ignition OFF state (However, the shift must be in the P range).
