Maintenance and care
●Remove loose dirt using a vacuum cleaner.
●Apply a mild soap solution to the synthetic leather using a sponge
or soft cloth.
●Allow the solution to soak in for a few minutes. Remove the dirt and
wipe off the solution with a clean, damp cloth.
■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.
Cleaning the synthetic leather areas
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. 42)
An electrical malfunction may cause the airbags to deploy or not function
properly, 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.

7-2. Maintenance
■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 replacement or if
a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
■Resetting the maintenance required reminder light/message indicating
maintenance is required (U.S.A. only)
After the required maintenance is preformed according to the maintenance
schedule, please reset the reminder light/message.
To reset the reminder light/message, follow the procedures described below:
Switch the display to the trip meter “A” (P. 91) when the hybrid system is
operating.
Turn the power switch off.
While pressing the MPH or km/h button (P. 93), turn the power switch to
ON mode (do not start the hybrid system because otherwise the reset
mode will be canceled). Continue to press and hold the button until the trip
meter displays “000000” and the indicator stops flashing to indicate that the
reset is complete.
■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 the operation 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
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.
WARNING
■If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and
possible serious injury or death.
■Handling of the 12-volt battery
●Engine exhaust, some of its constituents, and a wide variety of automobile
components contain or emit chemicals known to the State of California to
cause cancer and birth defects and other reproductive harm. Work in a
well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by
component wear contain or emit chemicals known to the State of Califor-
nia to cause cancer and birth defects or other reproductive harm. Avoid
exposure and wash any affected area immediately.
●12-volt battery posts, terminals and related accessories contain lead and
lead compounds which are known to cause brain damage. Wash your
hands after handling. (P. 439)

Emission inspection and maintenance (I/M)
programs
The OBD system determines that a problem exists somewhere in the
emission control system. Your vehicle may not pass the I/M test and
may need to be repaired. Contact your Toyota dealer to service the
vehicle.
●When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary
malfunction and your vehicle may not pass the I/M test.
The error code in the OBD system will not be cleared unless the vehi-
cle is driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system
monitors the operation of the emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after sev-
eral driving trips
If your vehicle does not pass the I/M test

there are no loose connections, cracks, or loose clamps.

■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
●Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible 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 doors.
●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-volt battery is
reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the power before disconnect the 12-volt battery. Take extra care when con-
necting the 12-volt battery if the power switch mode prior to discharge is
unknown.
●Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.
