4-1. Before driving
Driving
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This is due to automatic up-shifting control or down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is firmly or quickly
depressed
■Restraining the engine output (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the engine output may be
restrained.
●A warning message is displayed on the
multi-information display while the sys- tem is operating. ( P.378)
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is
performed, the engine output may be restrained.• When the shift position is shifted from R
to D, D or M to R, N to R, P to D*, or P to
R* with the accelerator pedal depressed,
a warning message appears on the multi- information display. If a warning message is shown on the multi-information display,
read the message and follow the instruc- tions.• When the accelerator pedal is depressed
too much while the vehicle is in reverse.*: Depending on the situation, the shift posi-
tion may not be changed.
●While Drive-Start Control is being acti- vated, your vehicle may have trouble escaping from the mud or fresh snow. In
such case, deactivate TRC ( P.263) to cancel Drive Start Control so that the vehicle may become able to escape from
the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observing
the following precautions is recommended:
●For the first 300 km (186 miles):
Avoid sudden stops.
●For the first 1000 km (621 miles):
• Do not drive at extremely high speeds. • Avoid sudden acceleration.• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type park- ing brake system. This type of brake system needs bedding-down of the brake shoes
periodically or whenever the parking brake shoes and/or drum are replaced. Have any authorized Lexus retailer or Lexus autho-
rized repairer, or any reliable repairer, per- form the bedding down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registra- tion laws and confirm the availability of the
correct fuel. ( P.412)
■Brake pads and discs
The brake pads and discs are designed for use under high load conditions. Therefore, brake noise may be generated depending
on the vehicle speed, braking force and vehicle environment (temperature, humid-ity, etc.).
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.

4-1. Before driving
WARNING
■When starting the vehicle
LC500: Always keep your foot on the
brake pedal while stopped with the engine running. This prevents the vehicle from creeping.
LC500h: Always keep your foot on the brake pedal while stopped with the
“READY” indicator is illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelera-tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera-
tor pedal instead of the brake pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in
operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress
the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay
response in an emergency, resulting in an accident.
●LC500h: The driver should pay extra attention to pedestrians when the vehi-
cle is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians may mis-
judge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.The exhaust system and exhaust gases
can be extremely hot. These hot parts may cause a fire if there is any flamma-ble material nearby.
●During normal driving, do not turn off the engine . Turning
the engine off while driving will not cause loss of steering or braking control, however, power
assist to the steering will be lost. This will make it more difficult to steer smoothly, so you should pull over and
stop the vehicle as soon as it is safe to do so. In the event of an emergency, such as if
it becomes impossible to stop the vehi- cle in the normal way: P.360
●Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill. Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P.173, 179)
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear view mirrors while driv-
ing. Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not outside the vehicle.
■When driving on slippery road sur-
faces
●Sudden braking, acceleration and
steering may cause tire slippage and reduce your ability to control the vehi-cle.
●Sudden acceleration, engine braking
due to shifting, or changes in engine speed could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly
depress the brake pedal to make sure that the brakes are functioning prop-erly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one side are wet and not functioning properly, steering con-
trol may be affected.

Driving
WARNING
■When shifting the shift position
●LC500: Do not let the vehicle roll
backward while a forward driving posi- tion is selected, or roll forward while the shift position is in R.
Doing so may cause the engine to stall or lead to poor brake and steering performance, resulting in an accident
or damage to the vehicle. LC500h: Do not let the vehicle roll backward while a forward driving posi-
tion is selected, or roll forward while the shift position is in R. Doing so may result in an accident or
damage to the vehicle.
●Do not shift the shift position to P while the vehicle is moving. Doing so can damage the transmission
and may result in a loss of vehicle con- trol.
●Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle con-trol.
●Do not shift the shift position to a driv-
ing position while the vehicle is moving backward. Doing so can damage the transmission
and may result in a loss of vehicle con- trol.
●LC500: Changing the shift position to N while the vehicle is moving will dis-
engage the engine from the transmis- sion. Engine braking is not available when N is selected.
LC500h: Changing the shift position to N while the vehicle is moving will disengage the hybrid system. Engine
braking is not available with the hybrid system disengaged.
●Be careful not to change the shift posi-tion with the accelerator pedal
depressed. Changing the shift position to any positions other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift posi-tion displayed on the shift position indi-
cator inside the meter.
■Brake pad wear
If any of the following situations occur,
have the brake pads checked and replaced by any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer as soon as possible.
●If the thickness of the brake pads
exceeds the brake pad wear limit when visually checking all four brake pads (for the brake pad wear limit, refer to
P.418)
●If “Brake Pad Wear Visit Your Dealer”
is displayed (only the right-side pads can be detected)
Rotor damage may result if the pads are not replaced when needed. Moderate
levels of the brake pad and disc wear allow enhanced braking power. As a result, the discs may wear more quickly
than conventional brake discs. Therefore, when replacing the brake pads, Lexus recommends that you also have the
thickness of the discs measured. It is dan- gerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.

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.
