1-2. Child safety
For safety and security
WARNING
■When installing a child restraint sys- tem
For safety reasons, always install a child restraint system in a rear seat. In the event that the rear seat cannot be used,
the front seat can be used as long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (inflation) may cause serious
injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off sys- tem is set to “ON”.If it is left off, the airbag may not deploy in
the event of an accident, which may result in serious injury or even death.
Riding with children
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the window lock switch to
avoid children operating the
power window accidentally.
( P.152)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the vehicle, and never allow children to have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the windows or other features of the vehicle. In addi-
tion, heat build-up or extremely cold temperatures inside the vehicle can be fatal to children.

4-5. Using the driving support systems
Driving
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 camera sensor, preventing the sys-
tem from operating properly*2:
• Pedestrians shorter than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.)
• Pedestrians wearing oversized clothing (a rain coat, long skirt, etc.), making their silhouette obscure
• Pedestrians who are carrying large bag- gage, holding an umbrella, etc., hiding part of their body
• Pedestrians who are bending forward or squatting• Pedestrians who are pushing a stroller,
wheelchair, bicycle or other vehicle • Groups of pedestrians which are close together
• Pedestrians who are wearing white and look extremely bright• Pedestrians in the dark, such as at night
or while in a tunnel • Pedestrians whose clothing appears to be nearly the same color or brightness as
their surroundings • Pedestrians near walls, fences, guardrails, or large objects
• Pedestrians who are on a metal object (manhole cover, steel plate, etc.) on the road
• Pedestrians who are walking fast • Pedestrians who are changing speed abruptly
• Pedestrians running out from behind a vehicle or a large object• Pedestrians who are extremely close to
the side of the vehicle (outside rear view mirror, etc.)*2: Depending on the region in which the
vehicle was sold, the pedestrian detec-
tion function may not be available.
■If the PCS warning light flashes and a
warning message is displayed on the multi-information display
The pre-collision system may be temporar- ily unavailable or there may be a malfunc-
tion in the system. In this case, read the warning message and follow the instruction.
●In the following situations, the warning light will turn off, the message will disap-pear and the system will become opera-
tional when normal operating conditions return:• When the radar sensor or camera sensor
or the area around either sensor is hot, such as in the sun• When the radar sensor or camera sensor
or the area around either sensor is cold, such as in an extremely cold environment• When the radar sensor or front grille
emblem is dirty or covered with snow, etc.•When the part of the windshield in front
of the camera sensor is fogged up or cov- ered with condensation or ice (Defog-ging the windshield: P.281)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the cam-
era sensor
●If the PCS warning light continues to flash
or the warning message does not disap- pear, the system may be malfunctioning. Have the vehicle inspected by any autho-
rized Lexus retailer or Lexus authorized repairer, or any reliable repairer immedi-
ately.
■If VSC is disabled
●If VSC is disabled ( P.263), 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.

6-3. Do-it-yourself maintenance
Maintenance and care
Vehicles with front and rear tires of
the same size
Vehicles with front and rear tires of
differing sizes
To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
■When rotating the tires
Make sure that the engine switch is off. If the tires are rotated while
the engine switch is in IGNITION ON mode , the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch to off and then to IGNITION ON mode ,
or initialize the tire pr essure warning system after checking that the tire pressure is prop-erly adjusted.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
conditions.)
A run-flat tire has a mark on
the side wall.
Make sure to replace the flat tire before the
vehicle has been driven for near 160 km
(100 miles). 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 performanc e 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.374)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information

display. (P.92)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop- erly.• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.• A tire has been replaced with a tire that is
not of the specified size. • Tire chains etc. are equipped.• An auxiliary-supported run-flat tire is
equipped. • If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.• If wheels without tire pressure warning
valves and transmitters are used. • If the ID code on the tire pressure warn-ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing situations. • Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise• When carrying a portable radio, cellular
phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rap-
idly for example when a tire has burst, the warning may not function.
■Warning performance of the tire pres-sure warning system
The warning of the tire pressure warning system will change in accordance with the
conditions under which it was initialized. For this reason, the system may give a warning
even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
