(Brake Override System)●
When the accelerator and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.●
A warning message is displayed on the
multi-information display while the sys-
tem is operating.■
Restraining sudden start (Drive-Start
Control)●
When the following unusual operation is
performed, the hybrid system output may
be restrained.
• When the shift position is shifted from R
to D, D to R, N to R, P to D *
, or P to R *
(D
includes M) with the accelerator pedal
depressed, a warning message appears
on the multi-information display. If a
warning message is shown on the
multi-information disp lay, read the mes-
sage and follow the instruction.
• When the accelerator pedal is depressed
too much while the vehicle is in reverse. *
: Depending on the situation, the shift
position 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 TRAC ( → P.304)
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 186 miles (300 km):
Avoid sudden stops.
●
For the first 621 miles (1000 km):
• 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 your
Lexus dealer perform the bedding down
operation. ■
Brake pads and discs (F SPORT models)
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.). ■
Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. ( → P.461)
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury. ■
When starting the vehicle
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.

160 4-1. Before driving
LS500h_OM_OM50F42U_(U) WARNING
• 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.●
The driver should pay extra attention
to pedestrians when the vehicle is
powered only by the electric motor
(traction motor). As there is no engine
noise, the pedestrians may misjudge
the vehicle’s movement. Even with the
vehicle proximity notification system
activate, 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 hybrid system. Turning the hybrid
system 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 diffi-
cult 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.420
●
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.174) ●
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 result in
tire failure, 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. ●
Sudden acceleration, engine braking
due to shifting, or changes in engine
speed could cause the vehicle to skid.
●
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
●
Do not let the vehicle roll backward
while a forward driving position is
selected, or roll forw ard while the shift
position is in R.
Doing so may result in an accident or
damage to the vehicle.

1614-1. Before driving
LS500h_OM_OM50F42U_(U) 4
Driving WARNING●
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.●
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.465) ●
If a warning message is displayed on
the multi-information display (only the
right-side pads can be detected)
Rotor damage may result if the pads are
not replaced when needed.
F SPORT models: 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 dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded. ■
When the vehicle is stopped ●
Do not depress the accelerator pedal
unnecessarily.
If the shift position is any position other
than P or N, the vehicle may acceler-
ate suddenly and unexpectedly, caus-
ing an accident. ●
In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while
stopped with the “READY” indicator is
illuminated, and apply the parking
brake as necessary.
●
If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.
●
Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.

162 4-1. Before driving
LS500h_OM_OM50F42U_(U) WARNING■
When the vehicle is parked●
Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter
or spray can, and may lead to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing
the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.●
Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.●
Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument pane l or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle.
●
Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
●
Always apply the parking brake, shift
the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended
while the “READY” indicator is illumi-
nated.
●
Do not touch the exhaust pipes while
the “READY” indicator is illuminated
or immediately after turning the hybrid
system off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the hybrid system off. Other-
wise, if you accident ally move the shift
lever or depress the accelerator pedal,
this could cause an accident or fire due
to hybrid system overheating. Addition-
ally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may col-
lect and enter the vehicle, leading to
death or a serious health hazard. ■
When braking ●
When the brakes are wet, drive more
cautiously.
Braking distance in creases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle. ●
If the electronically controlled brake
system does not operate, do not follow
other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will in crease. Have your
brakes fixed immediately. ●
The brake system consists of 2 or more
individual hydraulic systems; if one of
the systems fails, the other(s) will still
operate. In this case, the brake pedal
should be depressed more firmly than
usual and the braking distance will
increase. Have your brakes fixed
immediately.
■
If the vehicle becomes stuck
Do not spin the wheels excessively when
a driven wheel is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.

1654-1. Before driving
LS500h_OM_OM50F42U_(U) 4
Driving *3
: C =Available cargo and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D *4
lb. (kg) = E *5
lb. (kg)*4
: D =Additional weight of people *5
: E =Available cargo and luggage load
As shown in the example above, if the
number of occupants increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle. 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
• In front of the Center Display ●
Secure all items in the occupant com-
partment. ■
Capacity and distribution ●
Do not exceed the maximum axle
weight rating or the total vehicle
weight rating. ●
Even if the total load of occupant’s
weight and the cargo load is less than
the total load capacity, do not apply the
load unevenly. Improper loading may
cause deterioration of steering or
braking control which may cause
death or serious injury.
