Driving
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and shift the shift position to P and block the wheel
under the vehicle without setting the parking brake. The parking brake
may freeze up, preventing it from being released. If the vehicle is
parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle
to move unexpectedly, possibly leading to an accident.
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
3.0 mm (0.12 in.)
30.0 mm (1.18 in.)
10.0 mm (0.39 in.)
Cross chain
4.0 mm (0.16 in.)
25.0 mm (0.98 in.)
14.0 mm (0.55 in.)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.

WARNING
QDriving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
O Use tires of the specified size.
O Maintain the recommended level of air pressure.
O Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
O Use snow tires on all, not just some wheels.
Q Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
O Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
O Avoid driving on bumpy road surfaces or over potholes.
O Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
O Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
O Do not use LTA (Lane Tracing Assist).
Q When parking the vehicle
When parking the vehicle without applying the parking brake, ma ke sure to
chock the wheels. If you do not chock the wheels, the vehicle m ay move
unexpectedly, possibly resulting in an accident.
NOTICE
Q Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorize d Toyota
retailer or Toyota authorized repairer, or any reliable repaire r or legitimate
tire retailers.
This is because the removal and attachment of snow tires affect s the opera-
tion of the tire pressure warning valves and transmitters.

Maintenance and care
XRegistering ID codes
The 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 register the ID code. Have the ID code
registered by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
QWhen to replace your vehicle’s tires
Tires should be replaced if:
OThe treadwear indicators are showing on a tire.
OYou have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage.
OA 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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
QReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays
on to indicate a system malfunction.
QTire 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.
QRoutine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.
QIf the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
QLow profile tires (vehicles with 215/45R17 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 or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.

Maintenance and care
QWhen replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressu re. Whenever
wheels are replaced, tire pressure warning valves and transmitt ers must be
installed. ( P. 601)
WARNING
QWhen replacing wheels
O Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may resu lt in a loss of handling control.
O Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
Q When installing the wheel nuts
Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened, lead-
ing to bolt or disc wheel damage. In addition, the oil or greas e can cause the
wheel nuts to loosen and the wheel may fall off, causing an acc ident and
resulting in death or serious injury. Remove any oil or grease from the wheel
bolts or wheel nuts.
Q Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possi bly causing an
accident.
NOTICE
Q Replacing tire pressure warning valves and transmitters
O Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by an y autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer
or other qualified service shop. In addition, make sure to purc hase your
tire pressure warning valves and transmitters at any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r.
O Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly with
non-genuine wheels.
