Check the battery as follows:
■Battery exterior
Make sure that the battery terminals are not corroded and that
there are no loose connections, cracks, or loose clamps.
Terminals
Hold-down clamp
■ Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sur e to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connectin g and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with a smar t key sys-
tem)
The engine may not start. Follow the procedure below to initial ize 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 possi ble 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 when the engine switch turned from off. However, the engine
will operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the batte ry is recon-
nected, the vehicle will return the engine switch mode to the s tatus it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.

Maintenance and care
■How to initialize the tire pressure warning systemVehicles without a smart key system:
Park the vehicle in a safe plac e and turn the engine switch to the
“LOCK” position.
Vehicles with a smart key system:
Park the vehicle in a safe place and turn the engine switch off .
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 551)
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.
Vehicles without a smart key system:
Turn the engine switch t o the “ON” position.
Vehicles with a smart key system:
Turn the engine switch to IGNITION ON mode.
Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks slowly 3 times.
“- -” will be displayed for inflation
pressure of each tire on the
multi-information display while
the tire pressure warning sys-
tem determines the position of
each tire.
When position of each tire is
determined, the inflation pres-
sure of each tire will be dis-
played on the multi-information
display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for
approximately 10 minutes.
When initialization is complete, the inflation pressure of each tire
will be displayed on the mu lti-information display.
Initialization will ta ke longer than approxi mately 10 minutes if the
vehicle is stopped for a long time, such as at traffic signals.

Maintenance and care
■The initialization operation (vehicles with the tire pressure warning
system)
●Make sure to carry out initializ ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld 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 s mart key
system) during initialization, it is not necessary to press the reset switch
again as initialization will rest art automatically when the engine switch
has been turned to the “ON” posi tion (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicl es 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 cond uct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with the conditions under which it was initialized. For t his reason,
the system may give a warning even if the tire pressure does no t reach a
low enough level, or if the pressure is higher than the pressur e that was
adjusted to when the sys tem was initialized.
■When initialization of the tire pressure warning system has fai led (if
equipped)
Initialization may take longer to complete if the vehicle is driven on an
unpaved road. When performing ini tialization, drive on a paved road if
possible. Depending on the driving environment and condition of the tires,
initialization will be completed in approximately 10 minutes. If initialization
is not complete after driving app roximately 10 minutes, continue driving
for a while.
If the inflation pressure of each tire is not displayed after d riving for
approximately 1 hour, perf orm the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then
drive straight (with occasional left and right turns) at approx imately
25mph (40 km/h) or more for ap proximately 10 to 20 minutes.
However, in the following situatio ns, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After performing initialization, t he tire pressure warning light blinks for
1 minute then stays on while driving.
If the inflation pressure of eac h tire is still not displayed, have the vehicle
inspected by you r Toyota dealer.
