7-1. Maintenance and care
●Working from top to bottom, liberally apply water to the vehicl e
body, wheel wells and underside of the vehicle to remove any di rt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughl y
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface and
harm your vehicle's paint.
● In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent t he vehicle from being cleaned properly or
result in damage to the rear spoiler.
■ High 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 ar eas continu-
ously.
■ When using a car wash (vehicles with a smart key system)
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In that case, f ollow the fol-
lowing correction procedures to wash the vehicle:
● Place the electronic key in a location 6 ft. (2 m) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)
● Set the electronic key to battery-saving mode to disable the sm art key sys-
tem. ( P. 142)

■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in rep lacement or if
a repair shop other than a Toyota dealer performs repairs, conf irm the war-
ranty coverage.
■ Resetting the message indicating ma intenance is required (U.S.A. only)
After the required maintenance is performed according to the ma intenance
schedule, please reset the message.
To reset the message, follow the procedures described below:
Vehicles without a smart key system: Turn the power switch to the “LOCK”
position with the trip meter A reading shown.
Vehicles with a smart key system: Turn the power switch off wit h the trip
meter A reading shown.
Vehicles without a smart key system: While pressing the “trip” switch (P.
100), turn the power switch to the “ON” position (do not start the hybrid sys-
tem, reset mode will be canceled).
Vehicles with a smart key system: While pressing the trip meter reset but-
ton ( P. 100), turn the power switch to the ON mode (do not start the
hybrid system, otherwise the reset mode will be canceled).
Continue to press and hold the button until the trip meter disp lays “000000”.
■ Allow inspection and repairs to be performed by a Toyota dealer
●Toyota technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about th e operations
of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise

• Water or washer fluid containing antifreeze
(for winter use)
• Funnel (used only for adding water or washer
fluid)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■When working on the engine compartment
● Vehicles without a smart key system: Make sure that the power s witch is in
the “LOCK” position and the “READY” indicator is off.

● Keep hands, clothing and tools away from the moving fan and eng ine
drive belt.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.

After recharging/reconnecting the 12-volt battery (vehicles wit h a smart
key system)
● Unlocking the doors using the smart key system may not be possi ble imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the do ors.
● Start the hybrid system with the power switch in ACCESSORY mode . The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-vol t battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power before disconnect the 12-volt battery. Take extra car e when con-
necting the 12-volt battery if the power switch mode prior to d ischarge is
unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
WARNING
■ Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric a cid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12-volt battery:
● Do not cause sparks by touching the 12-volt battery terminals w ith tools.
● Do not smoke or light a match near the 12-volt battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the 12-volt ba ttery.
● Keep children away from the 12-volt battery.
■ Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charg e the 12-
volt battery in a garage or closed room where there is insuffic ient ventila-
tion.

4367-3. Do-it-yourself maintenance
PRIUS c_U
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the dri ver is
warned by a warning light. ( P. 483)
◆Installing tire pressure warn ing valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
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
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter I D
codes registered by your Toyota dealer. ( P. 437)
◆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 in fla-
tion pressures
● When changing the tire size
When the tire pressure warning sy stem 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 (vehi-
cles without a smart key system) or the power switch (vehicles
with a smart key system) off.
Initialization cannot be perfo rmed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 543)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
