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.

4-5. Using the driving support systems
WARNING
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys- tem is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■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 TRC/VSC/ABS is acti-vated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/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 dr iving force, do not turn the TRC/VSC systems off unless
necessary.
■Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision 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.
■Replacing tires
Make sure that all tires 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, TRC and VSC systems will not
function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a
system to malfunction.

4-6. Driving tips
Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

6-3. 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 any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■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 tires. Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for
road and weather conditions.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Rotate the tires in the order shown.
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.
●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-belted 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 pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

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
