Effective range (areas within which the electronic key is detected)

When locking or unlocking the doors

The system can be operated when the electronic key is within about 2.3 ft. (0.7 m) of the driver’s door handle. (Only the door detecting the key can be oper- ated.)

The system can be operated when the electronic key is inside the vehicle.

Alarms and warning indicators

A combination of exterior and interior alarms as well as warning messages shown on the multi-information display are used to prevent theft of the vehicle and accidents resulting from erroneous operation. Take appropriate mea- sures in response to any warning message on the multi-information display. (P. 493)

The following table describes circumstances and correction procedures when only alarms are sounded.

Battery-saving function

The battery-saving function will be activated in order to prevent the electronic key battery and the battery from being discharged while the vehicle is not in operation for a long time.

In the following situations, the smart key system may take some time to unlock the doors.

The electronic key has been left in an area of approximately 6 ft. (2 m) of the outside of the vehicle for 10 minutes or longer.

The smart key system has not been used for 5 days or longer.

If the smart key system has not been used for 14 days or longer, the doors cannot be unlocked at any door except the driver’s door. In this case, take hold of the driver’s door handle, or use the wireless remote control or the mechanical key, to unlock the doors.

The system will resume operation when

The vehicle is locked using the door handle lock switch when carrying the electronic key on your person.

The vehicle is locked/unlocked using the wireless remote control. (P. 128)

The vehicle is locked/unlocked using the mechanical key. (P. 523)

Electronic Key Battery-Saving Function

When battery-saving mode is set, battery depletion is minimized by stopping the electronic key from receiving radio waves.

Press twice while pressing and

holding . Confirm that the electronic key indicator flashes 4 times.

While the battery-saving mode is set, the

smart key system cannot be used. To cancel the function, press any of the elec- tronic key buttons.

Conditions affecting operation

The smart key system uses weak radio waves. In the following situations, the communication between the electronic key and the vehicle may be affected, preventing the smart key system, wireless remote control and engine immobi- lizer system from operating properly. (Ways of coping: P. 523)

When the electronic key battery is depleted

Near a TV tower, electric power plant, gas station, radio station, large dis- play, airport or other facility that generates strong radio waves or electrical noise

When carrying a portable radio, cellular phone, cordless phone or other wireless communication device

When the electronic key is in contact with, or is covered by the following metallic objects

Cards to which aluminum foil is attached

Cigarette boxes that have aluminum foil inside

Metallic wallets or bags

Coins

Hand warmers made of metal

Media such as CDs and DVDs

When multiple electronic keys are in the vicinity

When other wireless keys (that emit radio waves) are being used nearby

When carrying the electronic key together with the following devices that emit radio waves

Another vehicle’s electronic key or a wireless key that emits radio waves

Personal computers or personal digital assistants (PDAs)

Digital audio players

Portable game systems

If window tint with a metallic content or metallic objects are attached to the back window

When the electronic key is placed near a battery charger or electronic devices

Note for the entry function

Even when the electronic key is within the effective range (detection areas), the system may not operate properly in the following cases:

The electronic key is too close to the window or outside door handle, near the ground, or in a high place when the doors are locked or unlocked.

The electronic key is on the instrument panel or floor, or in the console box or glove box when the engine is started or engine switch modes are changed.

Do not leave the electronic key on top of the instrument panel or near the door pockets when exiting the vehicle. Depending on the radio wave recep- tion conditions, it may be detected by the antenna outside the cabin and the door will become lockable from the outside, possibly trapping the electronic key inside the vehicle.

As long as the electronic key is within the effective range, the doors may be locked or unlocked by anyone. However, only the doors detecting the elec- tronic key can be used to unlock the vehicle.

Even if the electronic key is not inside the vehicle, it may be possible to start the engine if the electronic key is near the window.

The doors may unlock or lock if a large amount of water splashes on the door handle, such as in the rain or in a car wash, when the electronic key is within the effective range. (The doors will automatically be locked after approximately 60 seconds if the doors are not opened and closed.)

If the wireless remote control is used to lock the doors when the electronic key is near the vehicle, there is a possibility that the door may not be unlocked by the entry function. (Use the wireless remote control to unlock the doors.)

Touching the door lock or unlock sensor while wearing gloves may prevent lock or unlock operation. Remove the gloves and touch the lock sensor again.

When the lock operation is performed using the lock sensor, recognition sig- nals will be shown up to two consecutive times. After this, no recognition signals will be given.

If the door handle becomes wet while the electronic key is within the effec- tive range, the door may lock and unlock repeatedly. In this case, follow the following correction procedures to wash the vehicle:

Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (Take care to ensure that the key is not stolen.)

Set the electronic key to battery-saving mode to disable the smart key system. (P. 141)

If the electronic key is inside the vehicle and a door handle becomes wet during a car wash, a message may be shown on the multi-information dis- play and a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.

The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc. Clean the lock sensor and attempt to operate it again, or use the lock sensor on the lower part of the door handle.

If there is another electronic key in the detection area, it may take slightly longer to unlock the doors after the door handle is gripped.

A sudden handle operation or a handle operation immediately after entering the effective range may prevent the doors from being unlocked. Touch the door unlock sensor and check that the doors are unlocked before pulling the door handle again.

Fingernails may scrape against the door during operation of the door han- dle. Be careful not to injure fingernails or damage the surface of the door.

Note for the unlocking function

Gripping the door handle when wearing a glove may not unlock the door.

A sudden approach to the effective range or door handle may prevent the doors from being unlocked. In this case, return the door handle to the origi- nal position and check that the doors unlock before pulling the door handle again.

If there is another electronic key in the detection area, it may take slightly longer to unlock the doors after the door handle is gripped.

When the vehicle is not driven for extended periods

To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of the vehicle.

The smart key system can be deactivated in advance. (P. 564)

To operate the system properly

Make sure to carry the electronic key when operating the system. Do not get the electronic key too close to the vehicle when operating the system from the outside of the vehicle.

Depending on the position and holding condition of the electronic key, the key may not be detected correctly and the system may not operate properly. (The alarm may go off accidentally, or the door lock prevention function may not operate.)
