P. 455
■ Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer for details.
■ If a wrong key is used (vehicles with a smart key system)
The key cylinder rotates freely to isolate inside mechanism.
NOTICE
■To prevent key damage
● Do not drop the keys, subject them to strong shocks or bend them.
● Do not expose the keys to high temperatures for long periods of time.
● Do not get the keys wet or wash them in an ultrasonic washer etc.
● Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
● Do not disassemble the keys.
● Do not attach a sticker or anything else to the surface of the electronic key
and key (with a wireless remote control function).
● Vehicles with a smart key system: Do not place the keys near objects that
produce magnetic fields, such as TVs, audio systems and induction cook-
ers, or medical electrical equipment, such as low-frequency therapy equip-
ment.
■ Carrying the electronic key on your person (vehicles with a sma rt key
system)
Carry the electronic key 3.9 in. (10 cm) or more away from electric appli-
ances that are turned on. Radio waves emitted from electric app liances
within 3.9 in. (10 cm) of the electronic key may interfere with the key, caus-
ing the key to not function properly.
■ In case of a smart key system malfunction or other key-related prob-
lems (vehicles with a smart key system)
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.
■ When an electronic key is lost (vehicles with a smart key system)
If the electronic key remains lost, the risk of vehicle theft i ncreases signifi-
cantly. Visit your Toyota dealer immediately with all remaining electronic
keys that was provided with your vehicle.

play, airport or other facility that generates strong radio wav es 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

2924-5. Using the driving support systems
4RUNNER (U)
■Intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in the “ON” position (without a smart key system) or
the engine switch is in IGNITION ON mode (with a smart key syst em).
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
● Rear corner and rear center sensors:
• The engine switch is in the “ON” position (without a smart key system) or
the engine switch is in IGNITION ON mode (with a smart key syst em).
• The shift lever is in R.
■ Intuitive parking assist display
When an obstacle is detected while the Toyota parking assist mo nitor is in
use, the warning indicator will appear in the upper part of the screen even if
the display setting has been set to off.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
front corner and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s detection areas before the display is shown and the wa rning
beep sounds.
• Thin posts or objects lower than the sensor may not be detected for colli-
sion when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of air conditioning system.
■ Objects which the system may not be properly detected
●Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low obstacles
● Tall obstacles with upper sections projecting outwards in the d irection of
your vehicle
