4-1. Before driving
NOTICE
●When driving over bumps in the road, drive as slowly as possible to avoid damaging the wheels, underside of the
vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P.384)
■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-
cle:
●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 any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer check the following:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis- sion, differentials, 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 any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer immedi- ately.
■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.

4-2. Driving procedures
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 any authorized Lexus retailer
or Lexus authorized repairer, or any reliable repairer.
■When driving with cruise control or 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 cruise control or dynamic
radar cruise control 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. ( P.242)
■Restraining sudden start (Drive-Start Control)
 P.155
■AI-SHIFT
The AI-SHIFT automatically 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 M cancels the function.)
■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 required. In this case,
change the shift positi on following the mes- sages on the multi-information display.
■After recharging/reconnecting the 12-volt battery
 P.325
■Customization
Settings (e.g. Reverse warning buzzer) can
be changed. (Customizable features: P.423)
WARNING

P to another position even if the shift lever is operated. Wait until the “READY” indi-cator changes from a flashing to a solid
light, and then operate the shift lever again.
●The shift position can only be changed to M directly from D.
In addition, if an attempt is made to change the shift position by moving the shift lever or by pressing the P positi on 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 hybrid transmission
If the transmission fluid temperature is high,
“Transmission Fluid Temp High See Owner’s Manual” will be displayed on the multi-information display and the vehicle
will go into transmission protection mode automatically. Have the vehicle inspected by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
■When driving with cruise control or dynamic radar cruise control with full-speed range activated
●When cruise control or dynamic radar cruise control with full-speed range is
operating, the system does not respond to paddle shift switch operations.
●Even when the driving mode is switched to sport mode with the intent of enabling engine braking, cruise control or
dynamic radar cruise control with full- speed range is not canceled and engine
braking is not activated.

Maintenance and care
●Appreciable loss of power
●Strange engine noises

cate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immedi-
ately.)
●Flat-looking tires, excessive tire squeal
when cornering, uneven tire wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy feel-
ing brake pedal, pedal almost touches the floor, vehicle pulls to one side when brak-ing

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become elec-
trically energized. To avoid death or seri- ous injury, observe the following precautions.
■When working on the engine com-
partment
●LC500h: Make sure that the “IGNI-
TION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away
from the moving fan and engine drive belt.
●LC500: Be careful not to touch the engine, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.LC500h: Be careful not to touch the
engine, power control unit, radiator, exhaust manifold, etc. right after driv-ing as they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water imme-
diately. If you still experience discomfort, con-sult a doctor.
■When working near the electric cool-ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode , the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. ( P.323)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is
high. If the reservoir needs frequent refilling, it may indicate a serious problem.
