This indicates that gear shifting did not complete properly after the paddle shift
switches were operated.
Operate the paddle shift switches again. If the indicator does not return to normal
after a while, contact your Lexus dealer.
■Buzzer that sounds when the paddle shift switches are operated
In certain situations where gear shifting with the paddle shift switches is rejected, a
buzzer may sound twice.
■Reverse warning buzzer
A warning buzzer sounds to notify the driver when Reverse is selected.

If the vehicle is in motion, Reverse may not be selected even if the reverse selector
switch is operated.

■Shift speed
●When the driving mode is changed, the shift speed levels will be set as follows:
●Shift shock increases as the shift speed becomes faster.
■When parking the vehicle
There is no P (Park) setting for the ASG. When parking the vehicle, set the parking
brake, select 1st gear or Reverse, and ch eck that the gear indicator shows “D1”, “1”
or “R” before stopping the engine.
●Approximately one second after the engine is stopped, the vehicle will enter a
parked gear state.
If the vehicle fails to enter a parked gear state, a buzzer sounds and the gear
indicator flashes. Select Neutral and then follow the same procedure again.
●Make sure to stop the engine. Opening the driver’s door without first stopping
the engine will cause a warning to sound and Neutral to be automatically
selected after 5 seconds. Even if the driver’s door is not opened, a warning will
sound and Neutral will be automatically selected after 90 seconds.
■ASG operating sounds
●Even when the engine is stopped, operating sounds of the electric oil pump may
be heard. This is normal and does not indicate a malfunction.
●As the drive train of the LFA is designed to be especially responsive to acceler-
ator pedal operation, a sound may be heard from the transaxle when driving at
low engine speeds. This does not indicate a malfunction.
■Customization that can be configured at your Lexus dealer
The sound pattern of the reverse warning buzzer can be changed.
