■Pop Up Hood operational conditions
The Pop Up Hood will operate when the
vehicle detects an impact such as the fol-
lowing:
●The front bumper detects a frontal impact
equivalent to or grea ter than that of a
pedestrian while the vehicle being driven
within the operational speed range of
approximately 16 to 34 mph (25 to 55
km/h). (The system is operated by an
impact of threshold le vel or greater, even
in the case of a minor collision that may
not leave a trace on the front bumper.
Also, depending on the impact condi-
tions or vehicle speed, the system may
operate by a collision with a light or small
object or a small animal.)
●In other situations such as the following,
the system may operate when an impact
is applied to the lowe r part of the vehicle
or front bumper:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
■Conditions under which the Pop Up
Hood may not operate properly
●If a pedestrian collides with the right or
left corner of the front bumper or the side
of the vehicle. As such impacts may be
difficult to detect, the system may not
operate.
●If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate
properly.
■Conditions under which the Pop Up
Hood will not operate
The Pop Up Hood will not operate in the
following situations:
●Colliding with a lying person
●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.

• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill
• If the radar sensor or front camera is mis- aligned
●In some situations such as the following,
sufficient braking force may not be
obtained, preventing the system 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
●Some pedestrians such as the following
may not be detected by the radar sensor
and front camera, preventing the system
from operating properly:
• Pedestrians shorter than approximately 3.2 ft. (1 m) or tall er than approximately

Driving
WARNING
●When driving over roads with potholes
or uneven surfaces
■TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner-
ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
●When Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRAC and VSC.
■Hill- start assist control does not
operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/ABS/
VSC/VGRS*/DRS* is activated
The slip indicator light flashes. Always
drive carefully. Re ckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
*: Only when controlled by the VDIM
system.
■When the TRAC/VSC systems are
turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the systems to help ensure
vehicle stability and driving force, do not
turn the TRAC/VSC systems off unless
necessary.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.
■Secondary Collision Brake
Do not rely solely upon the Secondary
Collision Brake. This system is designed
to help reduce the possibility of further
damage due to a secondary collision,
however, that effect changes according
to various conditions. Overly relying on
the system may result in death or serious
injury.

2504-6. Driving tips
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
Perform the following according to the
driving conditions:
Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the
climate control system fan, remove
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and suspen-
sion, and adversely affect driving perfor-
mance.
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
Before driving the vehicle

3146-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on
a tire.
●You have tire damage such as cuts, splits,
cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus
dealer.
■Tire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
■Low profile tires (21-inch tires)
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard ti res. Be sure to use
snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for
road and weather conditions.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. ( P.397)
■Tire types
●Summer tires Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer
tires do not have the same traction per-
formance as snow tires, summer tires are
inadequate for driving on snow-covered
or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is
recommended. When installing snow
tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide
better traction in
snow and to be ade-
quate for driving in most winter condi-
tions as well as for use year-round. All
season tires, howeve r, do not have ade-
quate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow tires
For driving on snow-covered roads or icy
roads, we recommend us ing snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also
have radial construction. Do not install
studded tires without first checking local
regulations for possible restrictions.
Snow tires should be installed on all
wheels. ( P.250)
■If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain as well as danger-
ous handling characteristics, which may
lead to an accident resulting in death or
serious injury.

Maintenance and care
Tires cannot be rotated.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
A run-flat tire has a mark on
the sidewall.
Make sure to replace the flat tire before the
vehicle has been driven for near 100 miles
(160 km). Also, do not use a repaired tire.
■Run-flat tires
●The run-flat tires are for only this vehicle.
Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon-
strate the performance of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.352)
 The tire pressure detected by the
WARNING
●Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those
recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-b elted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
■Low profile tires (21-inch tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
●Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■If tire inflation pres sure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
