When driving
●Pre-collision braking:
• The pre-collision braking off button is not pressed.
• Vehicle speed is greater than about 9 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greater than about 9 mph (15 km/h).
●Pre-collision alert braking (vehicle with driver monitor system):
• The pre-collision braking off button is not pressed.
• The system determines that the driver is not facing forward.
• Vehicle speed is greater than about 9 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running ahead of you is greate r than about 24 mph (40 km/h).
■Conditions that may trigger the system even if there is no danger of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will roll up quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( P. 493, 502, 505)

CAUTION
■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 serious
injury.
●Use tires of the size specified.
●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.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents. 
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used,
or 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden turns and braking, as use of chains may adversely affect vehicle
handling.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tire s from Lexus dealers or legitimate tire
retailers. 
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.

FCC Warning:
Any unauthorized changes or modifications to this equipment will void the user’s
authority to operate this device.
●Laser products
• Do not take this unit apart or attempt to make any changes by yourself. 
This is an intricate unit that uses a lase r pickup to retrieve information from the
surface of compact discs. The laser is carefully shielded so that its rays remain
inside the cabinet. Therefore, never try to disassemble the player or alter any
of its parts since you may be exposed to laser rays and dangerous voltages.
• This product utilizes a laser. 
Use of controls or adjustments or pe rformance of procedures other than
those specified herein may result in hazardous radiation exposure.
NOTICE
■To prevent battery discharge
Do not leave the audio system on longer than necessary with the engine off.
■To avoid damaging the audio system
Take care not to spill drinks or other fluids over the audio system.

Radio Frequency Radiation Exposure. This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has
very low levels of RF energy that it de emed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and oper-
ated with at least 7.9 in. (20 cm) and more between the radiator and person’s body
(excluding extremities: hands, wrists, feet and legs).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
■Caution while driving
Do not connect portable players or operate the controls.
NOTICE

4-3. Do-it-yourself maintenance
Washer fluid
If any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high. 
If the reservoir needs frequent refilling, there may be a serious problem.
CAUTION
■When adding washer fluid
Do not add washer fluid when the hybrid system is hot or operating as washer fluid
contains alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid. 
Doing so may cause streaking on the vehicle’s painted surfaces.
■Diluting washer fluid
Dilute washer fluid with water as necessary. 
Refer to the freezing temperatures listed on the washer fluid tank.

Maintenance and care
Tires
Replace or rotate tires in accordance with maintenance schedules and
treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear indi-
cators is shown by the “TWI” or
“ ”

marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
pr
essure if not rotated.
■ Tire rotation
Rotate the tires in the order
sho
wn.
To equalize tire wear and extend
tire life, Lexus recommends that
tire rotation is carried out at the
same interval as tire inspection.
P225/45R18 91W tires: 
Do not fail to initialize the tire
pr
essure warning system after
tire rotation.
■ Tire pressure warning system
Your vehicle is equipped with a ti r
e pressure warning system that
uses tire pressure warning valves and transmitters to detect low tire
inflation pressure before serious problems arise. ( P. 4 9 5 , 504 ,
505)

4-3. Do-it-yourself maintenance
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lv
es and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes r
egistered by your Lexus
dealer. ( P. 4 3 9 )
Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following
circumstances:
● V
ehicles with P225/45R18 91W tires: When rotating front and rear
tires which have different tire inflation pressures
● When changing the tir
e size
When the tire pressure warning sys tem is initializ
ed, the current tire
inflation pressure is set as the benchmark pressure.
