1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL

NOTICE:

When disconnecting the cable from the negative (-) battery terminal, initialize the following system after the terminal is reconnected:

System Name

See Procedure

Back Door Closer System


Power Back Door System

2. PRECAUTIONS WHEN USING TECHSTREAM

(a) When using the Techstream to troubleshoot the smart key system:

Connect the Techstream to the DLC3 while the engine switch is off, and turn a door courtesy light switch on and off at intervals of 1.5 seconds until communication between the tester and vehicle begins.

(b) After all DTCs are cleared, check if the malfunction occurs again 6 seconds after the engine switch is turned on (IG).

3. PRECAUTION FOR DISCONNECTING AND CONNECTING CABLE OF NEGATIVE BATTERY TERMINAL

(a) Immediately after disconnecting or connecting the cable of the negative (-) battery terminal, the doors may not be unlocked by the smart key system. In this situation, lock and unlock the doors using the wireless function. Then, it will be possible to unlock doors using the smart key system.

4. PRECAUTIONS FOR KEY BATTERY AND VEHICLE BATTERY

(a) When the doors are locked, the vehicle battery is used to transmit radio waves. The battery may discharge if the vehicle remains stopped for a long time. If the vehicle is not to be used for a long time, remove the battery from the vehicle or cancel the smart key system.

(b) When the doors are locked and the key is in the detection area of a door electrical key oscillator, the key battery will be depleted due to regular communication between the key and vehicle. If the vehicle is not to be used, keep the key away from the vehicle (more than 2 m (6.56 ft.)).

5. PRECAUTION FOR KEY

(a) The key is a precision instrument. Be sure to observe the following:

(1) Do not drop the key, subject it to strong shocks or bend it.

(2) Do not keep the key in a high temperature area for a long time.

(3) Do not get the key wet or wash it in an ultrasonic washer etc.

(4) Keep the key away from magnets or magnetized items during use.

(5) Do not disassemble the key except when replacing the battery.

(6) Do not place the key near objects that produce magnetic fields such as TVs, audio systems and electrical ranges, or electrical medical equipment such as low-frequency therapy instruments.

6. PRECAUTIONS FOR THE SMART KEY SYSTEM (for Entry Function) INSPECTION

(a) Overall smart key system (for entry function):

(1) Make sure to carry the key.

(2) All registered keys for the vehicle should be available when repairing or diagnosing the smart key system (for entry function).

(b) The smart key system, wireless door lock control system and engine immobilizer system may not operate normally, or the size of the operation area may decrease in the following situations:

HINT:

This is because faint radio waves are used for key detection.

(1) When the key battery is depleted.

(2) When any facilities that generate strong radio waves or electrical noise such as a TV tower, power plant, gas station, broadcast station, video billboard or airport are located near the inspection site.

(3) When the key is located near a wireless device such as a radio, cellular phone or cordless telephone.

(4) When the key is in contact with or covered with a metal object similar to the following:

  • Metal or aluminum plated card
  • Aluminum film from a cigarette box
  • Metallic wallet or bag
  • Coins
  • Heating pad
  • Media such as CDs or DVDs

(5) When a wireless remote is operated near the vehicle.

(6) When the key is carried with following items:

  • Electrical Key or wireless remote from another vehicle
  • PC or similar handheld device (PDA etc.)
  • Digital audio player
  • Portable game device

(c) When a metallic film is applied to the back window glass

(d) Precautions for key detection

(1) When using the key outside the vehicle, do not keep it too close to the vehicle. Depending on the way the key is held, the key may not be detected properly and the system will not operate normally.

HINT:

In this situation, warning buzzer may sound accidentally or key confinement prevention function may not operate.

(2) Even the key is in a detection area, it may not function normally in the following situations:

  • When the doors are locked or unlocked with the key too close to a window or door outside handle, near the ground or in a high place
  • When the key is on the instrument panel, floor, rear package tray, a door pocket or in the glove box

(e) Precautions specific to the smart key system

(1) If the key is within the vehicle exterior detection area, the doors can be locked or unlocked even when a person other than the person carrying the key holds the door outside handle. However, doors other than the door that detects the key cannot be unlocked.

(2) If a large amount of water is applied to the door outside handle due to a car wash or heavy rain, and the key is within the vehicle exterior detection area, the doors may be locked or unlocked. However, even when the doors are unlocked, the doors will be locked again after approximately 30 seconds if a door is not opened.

(3) If the doors are locked using the wireless remote transmitter when the key is in the cabin or near the vehicle, it may not be possible to unlock the doors using the smart key system. In this situation, use the wireless function of the key to unlock the doors.

HINT:

If the doors are locked from inside the vehicle using the wireless transmitter, it would not be desirable for it to be possible to unlock the vehicle via the touch sensors on the front outside door handles. Thus, unlocking via the touch sensors is disabled because radio waves from the door electrical key oscillator might otherwise leak into the cabin, detect the key, and enable the front door outside handle touch sensors.

7. PRECAUTIONS FOR SMART DOOR UNLOCK FUNCTION

(a) When unlocking the doors, make sure to grasp the door outside handle ensuring contact with the sensor on the inner part of the handle. Pull the handle after confirming that the door has unlocked.

(b) When attempting to open a door suddenly or immediately after entering the vehicle exterior antenna detection area, the doors may not be unlocked. If the doors are not unlocked, return the door outside handle, to its original position. Pull the handle after confirming that the door has unlocked.

HINT:

Due to mechanical reasons the door cannot be unlocked when the handle is being pulled.

(c) If the door outside handle is grasped with gloved hands, unlocking may be delayed or may not occur.

(d) If another key is in the detection area, the unlocking time may be delayed.

(e) The doors cannot be unlocked within 3 seconds after the door lock operation.

8. PRECAUTIONS FOR SMART DOOR LOCK FUNCTION

(a) Be sure to touch the lock sensor on the door outside handle (depressed portion on the handle) to lock the doors.

(b) If the doors are not locked even when the lock sensor on the door outside handle is touched, touch both upper and lower lock sensors simultaneously.

(c) If the lock sensor is touched with gloved hands, locking may be delayed or may not occur.

(d) If water is applied to the door outside handle when washing the vehicle and carrying a key, lock and unlock operations may repeat. In this situation, keep the key more than 2 m (6.56 ft.) away from the vehicle and wash the vehicle (Be aware of the potential for key theft).

(e) If water is applied to the door outside handle due to a car wash or heavy rain with a key inside of the cabin, a warning message "Key is not detected" may be displayed and buzzer may sound outside of the vehicle. In this situation, the warning message will disappear and buzzer will stop when all the doors are locked.

(f) If ice, snow or dirt adheres to a lock sensor surface, the sensor may not react. In this situation, remove the ice, snow or dirt and touch the sensor again or touch the lock sensor on the lower part of the handle.
