XAir conditioning
OTurn the “A/C” switch ( ) off when it is not needed. Doing
so can help reduce excessive electricity and fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 539)
OUsing the Remote Air Conditioning System (P. 535) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
OWhen setting the charging schedule, selecting the start time set-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immediately after starting off by operating air
conditioning before charging is completed. (if equipped)
(P. 166)
XChecking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range 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 consumption.

5667-1. Maintenance and care
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
Cleaning and protecting the vehicle exterior
OWorking from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
OWash the vehicle body using a sponge or soft cloth, such as a
chamois.
OFor hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
OWipe away any water.
OWax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
QBefore car washes
Check that the fuel filler door and charging port lid on your vehicle are closed
properly.
QAutomatic car washes
OFold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
OBrushes used in automatic car washes may scratch the vehicle surface,
parts (wheel, etc.) and harm your vehicle’s paint.
ORear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
QHigh pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps
around the doors or perimeter of the windows, or spray these areas continu-
ously.
Perform the following to protect the vehicle and maintain it in
prime condition:

Tire inflation pressure
QEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
OReduced fuel economy
OReduced driving comfort and poor handling
OReduced tire life due to wear
OReduced safety
ODamage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
QInstructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
OCheck 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 1.5 km or 1 mile, you will get an accurate cold tire inflation
pressure reading.
OAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
OIt is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.
OPassengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. (P. 7 2 1 )

When trouble arises
WARNING
QDriving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of acciden ts.
Failing to do so may result in a loss of vehicle control and ca use death or
serious injury.
O Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
O If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 130 kPa (1.3 kgf/cm2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
QWhen performing an emergency repair
O A tire should only be repaired with the emergency tire puncture repair kit if
the damage is caused by a sharp object such as nail or screw pa ssing
through the tire tread.
Do not remove the sharp object from the tire. Removing the obje ct may
widen the opening and disenable em ergency repair with the repair kit.
O The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
O Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a mal function may
occur.
O Make sure the sealant bottle of the repair kit is in a vertical position. The
repair kit does not operate properly when it is laid.
Q Precautions for the emergency tire puncture repair kit
O The repair kit power source should be 12 V DC suitable for vehicle use. Do
not connect the repair kit to any other source.
O If fuel splatters on the repair kit, the repair kit may deteriorate. Take care
not to allow fuel to contact it.
O Place the repair kit in a storage to prevent it from being exposed to dirt or
water.
O Store the repair kit in the luggage compartment out of reach of children.
O Do not disassemble or modify the repair kit. Do not subject parts such as
the air pressure indicator to impacts. This may cause a malfunc tion.
