Using the mechanical key (vehicles with a smart key system)
To take out the mechanical key,
push the release button and take
the key out.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key. (P. 597)
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (P. 417)
Vehicles without a smart key system: Carry the master key for your own use
and provide the attendant with the valet key.
Vehicles with a smart key system: Remove the mechanical key for your own
use and provide the attendant with the electronic key only.
■ Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a key (without a smart key system) or mechanical key (with a
smart key system) is lost, a new key can be made by your Toyota dealer
using the key number plate. ( P. 595)
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons
are not likely to be pressed accidentally. Pressing a button may cause the
key to emit radio waves that could interfere with the operation of the aircraft.

4RUNNER_U
■Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
■ Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
depleting.
● When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of
the vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle
cannot be unlocked by a door other than the driver's door. To unlock the
vehicle, grip the driver's door handle or use the wireless remote control
or the mechanical key.
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. 4 7 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 597)

Conditions aff ecting 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
immobilizer system from operating properly. (Way of coping P. 597)
● 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 electri-
cal noise
● When carrying a portable radio, mobile 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

■Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● As the electronic key always transmits radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 528)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
■ Precautions when disc onnecting the battery
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use
the wireless remote control or the mechanical key to lock or unlock the
doors.
● The engine may not start on the first attempt after reconnecting the bat-
tery but will start normally after the second attempt. This is not a malfunc-
tion.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was disconnected. Before disconnecting the
battery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
when the battery was disconnected, be especially careful when reconnect-
ing the battery.

When stopping the engine with the shift lever in a position other than P
If the engine is stopped with the sh
ift lever in a position other than P,
the “ENGINE START STOP” switch will not be turned off but instead
be turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.

If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour with the shift lever in P, the “ENGINE
START STOP” switch will automatically turn off. However, this function can-
not entirely prevent battery discharge. Do not leave the vehicle with the
“ENGINE START STOP” switch in ACCESSORY or IGNITION ON mode for
long periods of time when the engine is not running.
■ Operation of the “ENG INE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
