Fuel filter (diesel engine only)
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional. Even if you decide to drain it yourself, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
The water in the fuel filter needs to be drained if the fuel filter warning
light comes on. (P. 564)
Vehicles without a smart entry & start system:
Turn the engine switch to the “LOCK” position.
Vehicles with a smart entry & start system:
Turn the “ENGINE START STOP” switch off.
Place a small tray under the drain plug to catch the water and
any fuel that comes out.
Turn the drain plug counterclock-
wise about 2 to 2 1/2 turns.
Operate the priming pump until
fuel begins to run out.
After draining, tighten the drain plug by hand.

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
disconnect the ground cable.
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
When disconnecting the 12-volt battery terminals
Always disconnect the negative (-) terminal first.
After recharging/reconnecting the 12-volt battery
Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecting the 12-volt battery. If this hap-
pens, use the wireless remote control or the mechanical key to lock/
unlock the doors.
Vehicles with an electronic key: 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.
Vehicles with an electronic key: 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 bat-
tery was disconnected. Make sure to turn off the power before discon-
nect the 12-volt battery. Take extra care when connecting the 12-volt
battery if the “POWER” switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
