671-4. Hybrid system
1
For safety and security
There are air intake vents under the
rear seats for the purpose of cooling
the hybrid battery (traction battery). If
the vents become blocked, the hybrid
battery input and output may be
restricted, leading to a reduction in
hybrid battery (traction battery) out-
put.When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact your Lexus dealer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.
NOTICE
■Hybrid battery (traction battery)
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid battery
(traction battery), the battery may be
damaged. Have the vehicle inspected by
your Lexus dealer.
Hybrid battery (traction bat-
tery) air intake vents
NOTICE
■Hybrid battery (traction battery) air
intake vents
●Make sure not to block the air intake
vent with anything, such as a seat
cover, plastic cover, or luggage. If the
vents become blocked, the hybrid bat-
tery (traction battery) input and output
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery)
output and a malfunction.
●When dust etc. has accumulated in the
air intake vent, periodically clean it
with a vacuum cleaner to prevent the
vent from clogging.
●Filters are installed to the air intake
vent. When the filters remain notice-
ably dirty even after cleaning the air
intake vent, filter cleaning or replace-
ment is recommended. When clean-
ing or replacing the filters, contact
your Lexus dealer.
Refer to P.279 for details on how to
clean the filters.
●Do not get water or foreign materials
in the air intake vent s as this may cause
a short circuit and damage the hybrid
battery (traction battery).

1804-3. Operating the lights and wipers
■Front door opening linked windshield
wiper stop function
When “AUTO” is selected and the wind-
shield wipers are operatin g, if a front door is
opened, the operation of the windshield
wipers will be stopped to prevent anyone
near the vehicle from being sprayed by
water from the wipers, provided the vehicle
is stopped. When the front door is closed,
wiper operation will resume.
■To protect the windshield wipers
If movement of the windshield wipers is
largely restricted by a foreign object such as
snow, the operation of the windshield wip-
ers may be stopped automatically to pro-
tect the windshield wipe rs. In this case, turn
the windshield wiper switch off and remove
the foreign object, and then use the wind-
shield wipers.
■When stopping the engine tem> in an emergency while driving
If the windshield wipers are operating when
the engine is stopped, the
windshield wipers will operate in high speed
operation. After the vehicle is stopped,
operation will return to normal when the
engine switch is turned to
IGNITION ON mode , or
operation will stop when the driver’s door is
opened.
■Customization
The rain-sensing oper ation setting can be
changed.
(Customizable features:  P.391)When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-
tions or when replacing a windshield
wiper insert, change the rest position of
the windshield wipers to the service
position using the wiper lever.
WARNING
■Caution regarding the use of wind-
shield wipers in “AUTO” mode
The windshield wipers may operate
unexpectedly if the sensor is touched or
the windshield is subj ect to vibration in
“AUTO” mode. Take care that your fin-
gers or anything else do not become
caught in the windshield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE
■When there is no washer fluid spray
from the nozzle
Damage to the washer fluid pump may
be caused if the lever is pulled toward
you and held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.

“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -31°F [-
35°C])
Canada:
“Toyota Super Long Life Coolant” is a mix-
ture of 55% coolant and 45% deionized
water. (Minimum temperature: -44°F [-
42°C])
For more details about engine coolant, con-
tact your Lexus dealer.
■If the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses,
engine/power control unit coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.

The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank.
WARNING
■When the engine is
hot
LC500: Do not remove the engine cool-
ant reservoir cap or th e coolant inlet cap.
(  P.366)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
LC500h: Do not remove the
engine/power control unit coolant reser-
voir caps or the coolant inlet cap.
(  P.369)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
NOTICE
■When adding coolant
Coolant is neithe r plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.
Checking the radiator and con-

LC500hThe 12-volt battery is located in the
trunk.
■Before recharging
When recharging, the 12-volt battery pro-
duces hydrogen gas which is flammable
and explosive. Therefore, observe the fol-
lowing precautions before recharging:
●If recharging with the 12-volt battery
installed on the vehicle, be sure to discon-
nect the ground cable.
●Make sure the power switch on the char-
ger is off when connecting and discon-
necting the charger cables to the 12-volt
battery.
■After recharging/reconnecting the 12-
volt battery
●Unlocking the doors using the smart
access system with pu sh-button start may
not be possible immediately after recon-
necting the 12-volt battery. If this hap-
pens, use the wireless remote control or
the mechanical key to lock/unlock the
doors.
●Start the engine with the
