CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is ope rating on the wet or slick roads
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a sufficient distance from the vehicle in front of you 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 roads with uneven pavement
■ When the Enhanced VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes and a buzzer sounds.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the speci-
fied tire pressure level.
The ABS and Enhanced VSC will not function correctly if different tires are
fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.

PRIUS_U_(OM47614U)
CAUTION
■Driving with snow chains
Observe the following precautions to reduce the risk of accidents.
Failing 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 con-
trol is maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers.
This is because the removal and attachment of snow tires affects the opera-
tion 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:
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
CAUTION:
Radio Frequency Radiation Exposure
This equipment complies with FCC radiation exposure limits set forth, for
uncontrolled equipment and meets the FCC radio frequency (RF) Exposure
Guidelines in Supplement C to OET65. This equipment has very low levels
of RF energy that it deemed to comply without maximum permissive expo-
sure 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).
Co-location:
This transmitter must not be co-located or operated in conjunction with any
other antenna or transmitter.
CAUTION
■Caution while driving
Do not use a cellular phone or connect the Bluetooth
® phone.
NOTICE
■When leaving the vehicle
Do not leave your mobile phone in the vehicle. The inside of the vehicle may
become hot, causing damage to the phone.

■ Certification for the garage door opener
This device complies with Part 15 of the FCC Rules and with RSS-210 of the
IC Rules.
Operation is subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
WARNING: This transmitter has been tested and complies with FCC and IC
rules. Changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the device.
CAUTION
■When programming a garage door or other remote control device
The garage door or other devices may operate, so ensure people and
objects are out of danger to prevent potential harm.
■ Conforming to federal safety standards
Do not use the HomeLink
 Compatible Transceiver with any garage door
opener or device that lacks safety stop and reverse features as required by
federal safety standards.
This includes any garage door that cannot detect an obstruction object. A
door or device without these features increases the risk of death or serious
injury.

Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and inflation pressure if not
rotated.
■ Tire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.
Do not fail to initialize the tire
pressure warning system
after tire rotation.
■The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise. (P. 426)
The compact spare tire is not equipped with a tire pressure
warning valve and transmitter.

Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warn ing valve and transmitter ID codes
must be registered in the tire pr essure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by Toyota dealer.
(  P. 378)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
● When changing the tire inflation pressure by changing traveling
speed or load weight, etc.
● When changing the tire size.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.

How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “POWER” switch to
OFF mode.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 468)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the “POWER” switch to ON mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
Wait for a few minutes with the ON mode, and then turn
“POWER” switch to OFF mode.

Registering ID codesThe tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Maximum load of tire
Check that the maximum load of the re placed tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR) , see the Certification Label.
