Before driving
Using the mechanical key (vehicles with smart key system)
Take out the mechanical key.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with

(
P. 539)
■ When required to leave a key to th e vehicle with a parking attendant
Lock the glove box as circumstances demand. ( P. 376)
Vehicles without smart key system: Carry the master key for your own use
and leave the valet key only with the attendant.
Vehicles with 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 is lost, a new key can be made by your Toyota dealer using
the key number plate. ( P. 538)
■ When riding in an aircraft (vehicles with smart key system)
When bringing an electronic key onto an aircraft, make sure you do not
press any buttons on the electronic key while inside the aircraft cabin. If you
are carrying an electronic key in your bag etc, ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the elec-
tronic key to emit radio waves that could interfere with the operation of the
aircraft.
