Digital key precautions

1844-1. Key information
Be sure to carry the electronic
key of the vehicle if traveling
to a location with unreliable
communications.
 If the smartphone battery is
depleted, the smartphone
cannot be used as Digital
Key. If the battery level is low,
be sure to charge the smart-
phone prior to going out.
 The Digital Key system is
related to the smart key sys-
tem. If the smart key system
has been deactivated in the
vehicle customization setting,
the Digital Key will also be
disabled.
 Depending on the radio wave
environment, the Digital Key
may not be able to be used.
( P.205)
 When transferring vehicle
ownership, make sure to
delete the Digital Keys.
 If the vehicle is not operated
for 14 days or more, the Digi-
tal Key will not connect auto-
matically. Therefore, it may
take some time before the
system operates after a door
handle is touched.
 A part of the services may be
stopped for a certain period of
time due to server mainte-
nance. However, registered
Digital Keys can be used
during the maintenance.
 A smartphone with the Digital Key App enabled will be able
to lock and unlock the doors,
start the hybrid system and
perform any other operations
as same as the electronic key
of the vehicle. Be especially
careful not to lose the smart-
phone or allow it to be stolen.
If the smartphone is lost or
stolen, contact your Toyota
dealer immediately.
 When taking your vehicle to a
Toyota dealer for an inspec-
tion or repairs, make sure to
bring an electronic key.
 With the Digital Key alone, no
vehicle lights will illuminate
when approached to the vehi-
cle. Also, with the Digital Key
alone, some functions, such
as the power back door’s
close & lock (walk-away)
function, etc., cannot be used.

cally be restored by moving the
