Operating the smart key system
Card key (if equipped)
- The card key is not waterproof.
- The mechanical key that is stored inside the card key should be used only if a problem arises, such as when the card key does not operate properly.
- If it is difficult to take out the mechanical key, push down the release button using a pen tip, etc. If it is still difficult to pull it out, use a coin, etc.
- To store the mechanical key in the card key, insert it while pressing the release button.
- If the battery cover is not installed and the battery falls out or if the battery was removed because the key got wet, reinstall the battery with the positive terminal facing the Toyota emblem.
When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any buttons on the elec-tronic key while inside the aircraft cabin. If you are carrying an elec-tronic key in your bag, etc., ensure that the buttons are not likely to be pressed accidentally. Pressing a button may cause the electronic key to emit radio waves that could inter-fere with the operation of the air-craft.
Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is about a year and a half.)
- If the battery becomes low, an alarm will sound in the cabin and a message will be shown on the multi-information display when the engine is stopped.
- To reduce key battery depletion when the electronic key is to not be used for long periods of time, set the electronic key to the bat-tery-saving mode.
- As the electronic key always receives radio waves, the battery will become depleted even if the electronic key is not used. The fol-lowing symptoms indicate that the electronic key battery may be depleted. Replace the battery when necessary.
- The smart key system or the wire-less remote control does not oper-ate.
- The detection area becomes smaller.
- The LED indicator on the key sur-face does not turn on.
To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of the following electri-cal appliances that produce a magnetic field:
- TVs
- Personal computers
- Cellular phones, cordless phones and battery chargers
- Recharging cellular phones or cordless phones
- Table lamps
- Induction cookers
If a message regarding the state of the electronic key or engine switch mode, etc. is shown
To prevent trapping the electronic key inside the vehicle, leaving the vehicle carrying the electronic key on your person without turning the engine switch to OFF or other pas-sengers from unintentionally taking the key out of the vehicle, etc., a message that prompts the user to confirm the state of the electronic key or engine switch mode may be shown on the multi-information dis-play. In those cases, follow the instructions on the display immedi-ately.
Replacing the battery
Confirmation of the number of registered keys
The number of keys already regis-tered to the vehicle can be con-firmed. Ask your Toyota dealer for details.
If “A New Key has been Regis-tered Contact Your Dealer for Details” is shown on the multi-information display
This message will be displayed each time the driver’s door is opened when the doors are unlocked from the outside for approximately 10 days after a new electronic key has been registered. If this message is displayed but you have not had a new electronic key registered, ask your Toyota dealer to check if an unknown electronic key (other than those in your posses-sion) has been registered.
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 a long period of time.
- Do not get the keys wet or wash them in an ultrasonic washer, etc.
- Do not attach metallic or mag-netic materials to the keys or place the keys close to such materials.
- Do not disassemble the keys.
NOTICE
- Do not attach a sticker or any-thing else to the surface of the electronic key.
- Do not place the keys near objects that produce magnetic fields, such as TVs, audio sys-tems and induction cookers, or medical electrical equipment, such as low-frequency therapy equipment.
Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or more away from elec-tric appliances that are turned on. Radio waves emitted from electric appliances within 3.9 in. (10 cm) of the electronic key may interfere with the key, causing the key to not function properly.
