1504-2. Driving procedures
LC500_LC500h_OM_OM11405U_(U)In addition, if an atte
mpt is made to change
the shift position by moving the shift lever or
by pressing the P position switch in any of
the following situations, the buzzer will
sound and the shifting operation will be dis-
abled or the shift position will automatically
change to N. When this happens, select an
appropriate shift position.
●Situations where the shifting operation
will be disabled:
• When an attempt is made to change the
shift position from P to another position
by moving the shift lever without depress-
ing the brake pedal.
• When an attempt is made to change the shift position from P or N to M by moving
the shift lever.
• When the P position switch is pressed
while the vehicle is running.
*1
●Situations where the shift position will
automatically change to N:
• When an attempt is made to select the R position by moving the shift lever when
the vehicle is moving forward.
*2
• When an attempt is made to select the D
position by moving the shift lever when
the vehicle is moving in reverse.
*3
• When the shift position is changed from R to M
●If N is selected while driving at a certain
speed, even if the shift lever is not held in
the N position, the shift position changes
to N. In this situation, the buzzer sounds
and a confirmation message is displayed
on the multi-information display to inform
the driver that the shift position has
changed to N.
*1: Shift position may be changed to P when
driving at extremely low speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
■Reverse warning buzzer
When shifting into R, a buzzer will sound to
inform the driver that the shift position is in
R.
■To protect the automatic transmission
If the automatic transmission fluid tempera-
ture is high, “Transmission Fluid Temp High
See Owner’s Manual” will be displayed on
the multi-information display and the vehi-
cle will go into transmission protection
mode automatically. Have the vehicle
inspected by your Lexus dealer.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not be acti-
vated because dynamic radar cruise con-
trol with full-speed range will not be
canceled.
●While driving in the D position, down-
shifting to 9, 8, 7, 6, 5 or 4.
●When switching the driving mode to
sport mode while driving in D position.

■AI-SHIFT
The AI-SHIFT automatica lly selects the suit-
able gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when
the shift position is in D. (Shifting the shift
position to the M position cancels the func-
tion.)
■If a message about a shift operation is
shown
To prevent the shift position from being
selected incorrectly or the vehicle from
moving unexpectedly, the shift position may
be changed automatically or operating the
shift lever may be requ ired. In this case,
change the shift position following the mes-
sages on the multi-information display.

transmission when the engine cool-
ant temperature is low, the auto-
matic transmission fluid
temperature is high or low, or other
reasons.
Also, the gear will not shift when the
vehicle speed is low, even if an upshift
operation is performed.
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the paddle shift switch is operated. (A
buzzer will sound twice.)
*1: To improve fuel efficiency and reduce
noise, set the shift position in D for nor-
mal driving. You can choose gear range
suitable for your driving situation by
operating the paddle shift switches.
*2: Any gear range can be fixed when driv-ing in M mode.
■For the shift positions
●When the power switch is off, the shift
position cannot be changed.
●When the power switch is in ON mode
(the hybrid system is not operating), the
shift position can only be changed to N.
●When the “READY” indicator is on, the
shift position can be changed from P to D,
N or R.
●When the “READY” indicator is flashing,
the shift position cannot be changed from
P to another position even if the shift lever
is operated. Wait until the “READY” indi-

●The shift position can only be changed to
M directly from D.
In addition, if an atte mpt is made to change
the shift position by moving the shift lever or
by pressing the P position switch in any of
the following situations, the buzzer will
sound and the shifting operation will be dis-

will go into transmission protection mode
automatically. Have the vehicle inspected
by your Lexus dealer.
■When driving with dynamic radar cruise
control with full-speed range activated
●When dynamic radar cruise control with
full-speed range is operating, the system
does not respond to paddle shift switch
operations.
●Even when the drivin g mode is switched
to sport mode with the intent of enabling
engine braking, dynamic radar cruise
control with full-speed range is not can-
celed and engine braking is not activated.
