*1: Open door warning buzzer:
The open door warning buzzer sounds to alert one or more of the doors is not
fully closed (with the vehicle having reached a speed of 5 km/h [3 mph]).
*2: Driver’s and front passenger’s seat belt buzzer:
For GCC countries*3, Yemen, Jordan, Lebanon and Syria
The driver’s and front passenger’s seat belt buzzer sounds to alert the driver and
front passenger that his or her seat belt is not fastened. Once the engine switch is
turned to IGNITION ON mode, the buzzer sounds for 6 seconds. If the vehicle
reaches a speed of 20 km/h (12 mph), the buzzer sounds once. If the seat belt is
still unfastened after 30 seconds, the buzzer will sound intermittently for 10 sec-
onds. Then, if the seat belt is still unfastened, the buzzer will sound in a different
tone for 20 more seconds.
Except for GCC countries*3, Yemen, Jordan, Lebanon and Syria
The driver’s and front passenger’s seat belt buzzer sounds to alert the driver and
front passenger that his or her seat belt is not fastened. The buzzer sounds inter-
mittently for 30 seconds after the vehicle reaches a speed of 20 km/h (12 mph).
Then, if the seat belt is still unfastened, the buzzer will sound in a different tone for

■When the tire pressure warning light comes on (vehicles with the tire pressure
warning system)
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust it to the appropriate level.
●If the warning light does not go out after several minutes, check that the tire infla-
tion pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted without
first allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes (vehicles with
the tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire (vehicles with the tire pressure warning
system)
The spare tire is also equipped with a tire pressure warning valve and transmitter. The
tire pressure warning light will turn on if the tire inflation pressure of the spare tire is
low. If a tire goes flat, the tire pressure warning light will not turn off even though the
flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly (vehi-
cles with the tire pressure warning system)
P. 561
■If the tire pressure warning light frequently comes on after blinking for 1 minute
(vehicles with the tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the engine switch is turned to IGNITION ON mode, have it checked by your Lexus
dealer.
■Warning buzzer
In some cases, the buzzer may not be heard due to ambient noise or sounds from the
audio system.

●When the vehicle speed deviates from the operating range of the LKA system
functions
●When the lane lines cannot be recognized
●When the steering wheel is turned as far as necessary to cause the vehicle to
change lanes
