Smart key system

The smart key system consists mainly of the following functions.

• Engine immobilizer function (For details, see "Engine immobilizer system" on page 18 in this Section.)

• Wireless remote control function (For details, see "Wireless remote control" on page 20 in this Section.)

• Push button start function (For details, see "How to start the engine" on page 316 in Section 3.)

• Entry function and start function (See "ENTRY FUNCTION AND START FUNCTION" described below.)

• Steering lock function (See "STEERING LOCK FUNCTION" described below.)

/l\ CAUTION

• People with implanted pacemakers or cardiac defibrillators should keep away from the smart key system antennas, because the radio waves may affect the operation of such devices. For the antenna locations see "ANTENNA LOCATION" on page 32 in this Section.

• Users of any electrical medical device other than implanted pacemakers and implanted cardiac defibrillators should consult the manufacturer of the device for information about its operation under the influence of radio waves. Radio waves could have unexpected effects on the operation of such medical devices.

• If necessary, the entry function can be disabled. See "DISABLING THE SMART KEY SYSTEM" on page 36 in this Section.

ENTRY FUNCTION AND START FUNCTION

Simply by carrying the key, you can lock and unlock the doors and start the engine.

Entry function—You can lock and unlock the doors and open the trunk without inserting the key in the keyholes. For further information, see "Side doors" on page 36 and "Trunk lid" on page 46 in this Section.

Start function—You can shift the power supply mode and start the engine when the electronic key is in the vehicle. For further information, see "Ignition switch" on page 159 in Section 1-7 and "How to start the engine" on page 316 in Section 3.

If the smart key system does not operate properly because of a system malfunction, consult your Toyota dealer. Make sure to bring all of the keys. They may be necessary to repair the system.

STEERING LOCK FUNCTION

When the driver's door is opened after turning off the engine, the steering wheel will lock.

The steering lock is automatically unlocked when the "ENGINE START STOP" switch (engine switch) is pressed. If the indicator light on the "ENGINE START STOP" switch flashes green, this indicates that the steering wheel remains locked. If the amber indicator light flashes, this indicates that the steering lock is malfunctioning. For details, see "How to start the engine" on page 316 in Section 3.

ANTENNA LOCATION

1. Antenna inside cabin and trunk

2. Antenna outside cabin and trunk

ACTUATION AREA

The entry function and start function are available to use when a registered key is in the actuation area.

1. Entry function actuation area—About 0.7 m (2 ft.) from each outside front door handle and the trunk opener switch

Only the door handle of the actuation area that the key holder is in can be operated.

If the key is close to the door handle, windows or the center of the rear bumper, on the ground or above the roof, the entry function may not be activated.

2. Start function actuation area—Inside of the cabin

The start function may not be activated, if the key is in the auxiliary box of the driver's side instrument panel and glove box, on the instrument panel, on the package tray, on the floor, etc.

In the following cases, the smart key system may not operate properly.

• When facilities issuing strong electromagnetic waves such as TV towers, electric power stations, broad casting stations are nearby.

• In places where automated payment facilities are installed (such as gas stations).

• When you are carrying a electronic key together with a mobile communications system such as a two-way radio or cellular phone.

• When the electronic key is in contact with or covered by a metallic object.

• When another person is operating a wireless remote control function on another vehicle near your vehicle.

• When the battery is discharged. To replace the battery, see "—Replacing battery" on page 28 in this Section.

• When the electronic key is near a high-voltage or noise-emitting device.

• When you are carrying an electronic key together with a key for another smart key system equipped vehicle or another instrument emitting radio waves.

• Depending on the position of the key or vehicle body shape, the key may not work well even within the actuation area.

• When the key surface is covered by a sticker, etc. that may cut off electromagnetic wave.

Even if the smart key system does not operate properly, you can still enter and start the engine. For further information, see "Side doors" on page 36 and "Trunk lid" on page 46 in this Section, and see "How to start the engine" on page 316 in Section 3.

STARTING THE ENGINE WHEN THE ELECTRONIC KEY BATTERY IS DISCHARGED

If the key indicator does not flash and the engine cannot be started by using the start function, the battery may be discharged. Replace the key battery as soon as possible. (See "Wireless remote control" on page 20 in this Section.)

However the engine can be started in the following procedures.

1. While the brake pedal is depressed, touch the Toyota logo side of the electronic key to the "ENGINE START STOP" switch.

2. Start the engine within 5 seconds after the green indicator light on the "ENGINE START STOP" switch comes on and a buzzer sounds.

BATTERY POWER SAVING

Both the vehicle and key transmitters are always sending signals to each other. To prevent battery drain, the smart key system is automatically deactivated in the following conditions:

• If the electronic key is left outside of the vehicle and within the effective range of the entry function actuation area for more than 10 minutes.

• If the door lock or unlock operation is not performed more than 2 weeks.

The key and the vehicle are communicating even while the vehicle is not being driven. Do not leave the key near the vehicle (within 2 m [7 ft.]).

The vehicle battery may drain if the vehicle is not used for a long period of time. To prevent battery drain, disconnect the battery negative (-) terminal or disable the smart key system. (For details about disable the smart key system, see "DISABLING THE SMART KEY SYSTEM" on page 36 in this Section.)

To reactivate the smart key system, perform any of the following:

(a) Press the lock button on the front outside door handle or trunk open button while carrying the electronic key.

(b) Perform a wireless remote control operation.

(c) Insert and turn the mechanical key in the keyhole of the driver's door.

If the electronic key receives strong electromagnetic waves over a period of time, the battery can be drastically run down. You should always keep the following electrical appliances at least 1 m (3 ft.) away from the electronic key.

• Personal computer

• Cellular phone or cordless phone recharger unit

• Electric light stand

• Fluorescent desk light
