391-1. For safe use
LS500_OM_(U)_1810 1
For safety and security ●
A frontal impact applied to the front
bumper while driving at speeds outside
of the operational speed range●
A side impact or rear impact●
A vehicle rollover (In some accident situ-
ations, the Pop Up Hood may operate.)
WARNING■
When the Pop Up Hood is operated●
Do not pull the hood lock release lever.
Doing so after the Pop Up Hood has
operated will further raise the hood
and may cause an injury. Do not drive
with the hood raised, as doing so may
block the driver’s vision, possibly caus-
ing an accident.●
Do not forcibly push down the hood.
As the popped up hood cannot be
lowered by hand, doing so may deform
the hood or cause an injury.●
If the Pop Up Hood has operated, have
it replaced by your Lexus dealer. If the
Pop Up Hood has operated, stop the
vehicle in a safe place and contact
your Lexus dealer.●
Do not touch the lifters immediately
after the Pop Up Hood has operated,
as the lifters may be hot and burn you.
NOTICE
■
Pop Up Hood precautions●
Make sure to close the hood before
driving, as the system may not operate
properly if the hood is not fully closed.
●
Make sure that all 4 tires are of the
specified size and inflated to the speci-
fied tire pressure. If tires of a different
size are used, the system may not
operate properly.
●
If something has hit the area around
the front bumper, the sensors may be
damaged even if the Pop Up Hood has
not operated. Have the vehicle
inspected by your Lexus dealer. ●
Do not remove or repair the parts or
wiring of the Pop Up Hood, as doing
so may cause accidental operation or
prevent the system from operating
properly. If repair or replacement is
necessary, contact your Lexus dealer. ●
Do not remove such components as
the front bumper, hood or suspension,
or replace them with non-genuine
parts, as doing so may prevent the sys-
tem from operating properly. ●
Do not install anything to the front
bumper or hood, as doing so may pre-
vent the sensors fr om detecting an
impact correctly and prevent the sys-
tem from operating properly. ●
Do not close the hood with force or
apply load to the lifters, as doing so
may damage the lifters and prevent the
system from operating properly. ●
Do not modify the suspension, as
changes made to the vehicle height
may prevent the system from operat-
ing properly.

Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location. ■
Stolen Vehicle Location
If your vehicle is stolen, Safety Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call
the Safety Connect response center at 1-800-25-LEXUS
(1-800-255-3987) in the United
States, 1-877-539-8777 in Puerto
Rico or 1-800-265-3987 in Canada,
and follow the prompts for Safety Con-
nect to initiate this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information is available at Lexus.com. ■
Emergency Assistance Button
(“SOS”)
In the event of an emergency on the
road, push the “SOS” button to reach
the Safety Connect response center.
The answering agent will determine
your vehicle’s location, assess the
emergency, and dispatch the neces-
sary assistance required. If you accidentally press the “SOS” button,
tell the response-center agent that you are
not experiencing an emergency.
■
Enhanced Roadside Assistance
Enhanced Roadside Assistance adds
GPS data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” but-
ton to reach a Safety Connect
response-center agent, who can help
with a wide range of needs, such as:
towing, flat tire, fuel delivery, etc. For a
description of the Roadside Assistance
services and their limitations, please
see the Safety Connect Terms and
Conditions, which are available at Safety Connect services

1594-1. Before driving
LS500_OM_(U)_1810 4
Driving WARNING●
Vehicles with Lexus Safety System + A:
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 increase. Have your
brakes fixed immediately.●
Vehicles without Lexus Safety System
+ A: Do not pump the brake pedal if
the engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.●
Vehicles without Lexus Safety System
+ A: The brake system consists of 2
individual hydraulic systems; if one of
the systems fails, the other 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.●
Vehicles with Lexus Safety System + A:
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. NOTICE■
When driving the vehicle ●
Do not depress the accelerator and
brake pedals at the same time during
driving, as this may restrain the engine
output. ●
Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill. ■
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. ■
Avoiding damage to vehicle parts ●
Do not turn the steering wheel fully in
either direction and hold it there for an
extended period of time.
Doing so may damage the power
steering motor. ●
When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
●
Make sure to idle the engine immedi-
ately after high-load driving. Stop the
engine only after the turbocharger has
cooled down.
Failure to do so may cause damage to
the turbocharger.
■
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.

160 4-1. Before driving
LS500_OM_(U)_1810 Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or XXX
lbs.” on your vehicle’s placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 − 750
(5  150) = 650 lbs.)
(5) Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-NOTICE
Information on what to do in case of a flat
tire (  P.429)■
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, transfer (AWD models), differen-
tial, 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,

LS500_OM_(U)_1810 4
Driving vehicle ahead that is using fog lights with-
out its headlights turned on is detected.●
House lights, street lig hts, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.●
The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles
ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient,
curve, condition of th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle●
The high beams may turn on or off unex-
pectedly.●
Bicycles or similar vehicles may not be
detected.●
In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog,
mist, ice, dirt, etc.
• When the windshield is cracked or dam-
aged
• When the camera sensor is deformed or
dirty
• When the temperature of the camera
sensor is extremely high
• When the surrounding brightness level is
equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles
ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle • When driving through an area of inter-
mittently changing brightness and dark-
ness
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking
curves or driving on a winding road
• When there is a highly reflective object
ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is
highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to
a flat tire, a trailer being towed, etc.
• When the headlights are changed
between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high
beams may be flashing or dazzling
pedestrians or other drivers ■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
●

LS500_OM_(U)_1810 ●
In some situations, such as the following,
the sensors may not detect the lane lines
or a safe space the vehicle can be steered
into, preventing the ac tive steering assist
from operating properly:
• When the white (yellow) lane lines are
difficult to see, such as when they are
faint, diverging/merging, or a shadow is
cast upon them
• When the lane is more wide or narrow
than normal
• When there is a light and dark pattern on
the road surface, such as due to road
repairs
• If the system determines that a collision
can be avoided by only using the brakes
• When a pedestrian is detected near the
centerline of the vehicle●
In some situations such as the following,
sufficient braking force or steering force
may not be obtained, preventing the sys-
tem from performing properly:
• If the braking functions cannot operate to
their full extent, such as when the brake
parts are extremely cold, extremely hot,
or wet
• If the vehicle is not properly maintained
(brakes or tires are excessively worn,
improper tire inflation pressure, etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface
• If there are deep ruts in the road
• When driving on a slope
• When driving on a horizontally slanted
road●
Some guardrails, such as the following,
may not be detected by the sensors, pre-
venting the system from operating prop-
erly:
• Guardrails which are less than approxi-
mately 1.9 ft. (60 cm) tall
• Short guardrails
• Irregularly-shaped guardrails (wire cable
guardrails, guardrails made of thin poles,
etc.)
• Guardrails which are not illuminated by
the headlights at night, in a tunnel, etc.
• Guardrails which appear to be nearly the
same color or brig htness as their sur-
roundings
• Guardrails which appear to be nearly the
same shape as their surroundings (walls,
etc.) • Guardrails which are over a metal object
(manhole cover, steel plate, etc.)
• Guardrails which are hidden behind thick
grass
• Guardrails which are extremely close to
the side of the vehicle (outside rear view
mirror, etc.)
• Curved guardrails or guardrails at the
entrance of a curve ●
In some situations su ch as the following,
the system may detect a pedestrian and
display a warning on the head-up display,
even though no pedestrian exists:
• If the front of the vehicle is raised or low-
ered, such as when the road surface is
uneven or undulating (due to ruts, etc.)
• When driving on a slope
• When driving on a horizontally slanted
road
• If the driver’s posture (driver seat posi-
tion) is extreme, such as excessively
reclined
• If the head-up display position is set
extremely high ■
If VSC is disabled ●
If VSC is disabled (  P.294), the pre-col-
lision brake assist and pre-collision brak-
ing functions are also disabled. ●
The PCS warning light will turn on and
“VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on
the multi-information display.
