2020 Lexus LC500h check engine light

1404-1. Before driving
WARNING
■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. Even
though the vehicle is equipped with the
vehicle proximity notification system,
drive with care as pedestrians in the
vicinity may still not notice the vehicle if
the surrounding area is noisy.
●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.330
●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.157, 163)
●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.
●Do not drive in excess of the speed
limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140
km/h) unless your vehicle has high-
speed capability tires. Driving over 85
mph (140 km/h) may re sult in tire fail-
ure, loss of control and possible injury.
Be sure to consult a tire dealer to
determine whether the tires on your
vehicle are high-speed capability tires
or not before driving at such speeds.
■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.

Driving
WARNING
●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.
■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 posi-
tion to any positions other than P or N
may lead to unexpected rapid acceler-
ation 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 occurs,
have the brake pads visually checked and
replaced by your Lexus dealer 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.382)
●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.

The wipers will automatically operate a couple of times after the washer squirts.
(After operating several times, the wipers
operate once more time
after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
■The windshield wiper and washer can be
operated when
The engine switch is in
IGNITION ON mode .
■Raindrop sensor
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
●If the wiper is turned to “AUTO” position
while the engine switch is
in IGNITION ON mode ,
the wipers will operat e once to show that
“AUTO” mode is activated.
●If the temperature of the raindrop sensor
is 185°F (85°C) or higher, or -22°F (-
30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is washer fluid in the wind-
shield washer fluid reservoir.

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.216)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.78)
Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption. In the N position, the
gasoline engine operates but electric-
ity cannot be generated. Also, when
using the air conditio ning system, etc.,
the hybrid battery (traction battery)
power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
