■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.
■ Reset the maintenance data (U.S.A. only)
After the required maintenance is performed according to the maintenance
schedule, please reset the maintenance data.
To reset the data, follow the procedure described below:
Using the trip meter
Vehicles without a smart key system: Turn the engine switch to the “LOCK”
position with the trip meter A reading shown.
Vehicles with a smart key system: Turn the engine switch off with the trip
meter A reading shown.
Vehicles without a smart key system: While pressing the trip meter reset
button ( P. 95), turn the engine switch to the “ON” position (do not start the
engine, reset mode will be canceled).
Vehicles with a smart key system: While pressing the trip meter reset but-
ton ( P. 95), turn the engine switch to the IGNITION ON mode (do not start
the engine, otherwise the reset mode will be canceled).
Continue to press and hold the button until the trip meter displays “000000”.
Using the multi-information display (vehicles with color display)
While the engine is running, switch the multi-information display to the “Set-
tings” screen. ( P. 94)
Select “Maintenance System” on the “Settings” screen.
Select “Yes” on the “Maintenance System” screen.
“Initialization Completed” will be displayed on the multi-information display
when the reset procedure has been completed.
■ 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 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
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.

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
●Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, 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 rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric co oling fans or radiator grille
Vehicles without a smart key system:
Be sure the engine switch is off.
With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 509)
Vehicles with a smart key system:
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 509)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

After recharging/reconnecting the battery (vehicles with a smart key sys-
tem)
The engine may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.
● Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the battery. If this happens, use the wireless
remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the battery is discon-
nected and reconnected, the vehicle will return the engine switch mode to
the status it was in before the battery was disconnected. Make sure to turn
off the engine before disconnecting the battery. Take extra care when con-
necting the battery if the engine switch mode prior to the battery being dis-
connected is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
WARNING
■ Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid 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
battery:
●Do not cause sparks by touching the battery terminals with tools.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the battery.
● Keep children away from the battery.

The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart key system) or off (vehicles with a smart key
system) during initialization, it is not necessary to press the reset switch
again as initialization will restart automatically when the engine switch
has been turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system) for the
next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●When operating the tire pressure wa
rning reset switch, the tire pressure
warning light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning
light blinks for 1 minute then stays on after driving for 20 minutes.
