Maintenance and care
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■ Water in the vehicle
● Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air intake vent, and in the luggage com-
partment.
Doing so may cause the hybrid battery (traction battery), electrical compo-
nents, etc. to malfunction or catch fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 40)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
● Vehicles with wireless charger:
Do not let the wireless charger ( P. 487) get wet. Failure to do so may
cause the charger to become hot and cause burns or could cause electric
shock resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

Maintenance and care
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
● Vehicles with an emergency tire puncture repair kit: Do not tow anything if
a tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.
■ When initializing the tire pressure warning system (if equipped)
Do not initialize the tire pressure wa rning system without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

5747-2. Steps to take in an emergency
PRIUS_OM_OM47F32E_(EE)
When using a flatbed truck to transport the vehicle, use tire strapping
belts. Refer to the owner’s manual of the flatbed truck for the tire
strapping method.
In order to suppress vehicle movement during transportation, set the
parking brake and turn the power switch off.
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelets. This should only be attempted on hard surfaced roads
for short distances at under 30 km/h (18 mph).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
