■When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
the following serious damage to the vehi-

●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, differential, etc.
●Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.
If the shift control system is damaged by
flooding, it may not be possible to shift
the shift position to P, or from P to other
positions. In this case, contact your Lexus
dealer.
■When parking the vehicle
Always set the parking brake, and shift
the shift position to P. Failure to do so
may cause the vehicle to move or the
vehicle may accelerate suddenly if the
accelerator pedal is accidentally
depressed.

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.

■If the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses,
engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.

hot
LC500: Do not remove the engine cool-
ant reservoir cap or th e coolant inlet cap.
(  P.378)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
