Before driving
PRIUS PHV_OM_OM47787U_(U)
■Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there
is improper tire inflation pressure in the tires, the driving range
when in EV mode will become shorter, and fuel consumption
when in HV mode will increase.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to increased fuel and electricity consump-
tion.
■Luggage
Carrying heavy luggage can require excessive energy. Avoid
leaving unnecessary luggage in the vehicle.
Also, equipping a large roof rack can cause excessive energy
consumption in the same way as carrying heavy luggage.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

CAUTION
■Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern and total load capacity. In addition, make sure that the tires are
inflated to the recommended tire inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Toyota dealer 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.

Maintenance and care
Installing tire pressure warning valves and transmitters
When 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 ID codes must be registered in the tire pressure warn-
ing computer and the tire pressure warning system must be initial-
ized. Have tire pressure warning valve and transmitter ID codes
registered by your Toyota dealer. (→P. 4 7 9 )
■Tire pressure warning system

Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating front and rear tires which have different tire infla-
tion pressures
●When changing the tire size
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the “POWER” switch
off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (→P. 6 1 9 )
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The tire pressure warning system will
operate based on this pressure level.
Turn the “POWER” switch to ON mode.

■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, and bulges indicating internal damage.
●A tire goes flat repeatedly or cannot 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 pressure warning system will not work properly. After
driving for about 20 minutes, the tire pressure warning light blinks for
1 minute and stays on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■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.

Maintenance and care
■Maximum load of tire
Check that the maximum load of the replacement 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.
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires
should be installed on all wheels. (→P. 3 4 9 )
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. 6 2 5 )

■Initializing the tire pressure warning system
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have not been recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for 20 minutes.
