2021 Lexus LC500 check engine

1444-1. 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.338
●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.162, 169)
●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.392)
●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 vehicle will lean abnormally.
Information on what to do in case of a flat
tire ( P.362)
■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 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.
Cargo and luggage
Take notice of the following infor-
mation about storage precautions,
cargo capacity and load:
WARNING
■Things that must not be carried in the
trunk
The following things may cause a fire if
loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s vision, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the trunk
whenever possible.
●Do not place cargo or luggage in or on
the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
