In addition to the above, in some situations, such as the follo wing, the emer-
gency steering assist may not operate.
• When the white (yellow) lane lines are difficult to see, such as when they
are faint, diverging/merging, or a shadow is cast upon them
• When the lane is wider or narrower than normal
• When there is a light and dark pattern on the road surface, su ch as due to
road repairs
• When a pedestrian is detected near the centerline of the vehic le
• When the target is too close
• When there is insufficient safe or unobstructed space for the vehicle to be
steered into
• If oncoming vehicle is present
• If VSC function is operating
● In some situations such as the following, sufficient braking force or steering
force may not be obtained, preventing the system from performin g 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 sli ppery sur-
face
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■ If VSC is disabled
●If VSC is disabled ( P. 302), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off. Pre-Col lision
Brake System Unavailable.” will be displayed on the multi-infor mation dis-
play. • While making a right/left turn, when a
pedestrian approaches from behind
or side of your vehicle

How to initialize the tire pressure warning system
Park the vehicle in a safe plac e and turn the engine switch to the
“LOCK” position (vehicles with out a smart key system) or off
(vehicles with a sm art key system).
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 482)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Turn the engine switch to the “ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system).
Press “” or “ ” of the meter control switch to select .
(  P. 100)

Maximum load of tire
Check that the maximum load of t
he replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axl e or the
rear axle, whichever is greater.
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to hi ghway
driving under dry conditions. Si nce summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e 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 si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 306)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost. 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. 4 8 7 )

The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch off during in itialization,
it is not necessary to press the reset swit ch again as initialization will
restart automatically when the en gine switch to the “ON” position (vehi-
cles without a smart key system) or IGNITION ON mode (vehicles with a
smart key system) for the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and cond uct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with driving conditions. F or this reason, the system may give a
warning even if the tire pressure does not reach a low enough l evel, or if
the pressure is higher than the pressure that was adjusted to w hen the
system was initialized.
■When initialization of the tire pressure warning system has fai led
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●When operating the initialization of the system, the tire pressure warning
light does not blink 3 times and the setting message does not a ppear on
the multi-information display.
●After driving for a certain period of time since the initializa tion has been
completed, the warning light comes on after blinking for 1 minute.

■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating , have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation p ressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based o nly on its appear-
ance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pre ssure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle is
balanced.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indica ted on the vehicle placard or tire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handl ing and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintena nce, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one mi nute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or al ternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning sys tem) to
continue to function properly.
