6-3. Do-it-yourself maintenance

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 sure to disconnect
the ground cable.

Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.

After recharging/reconnecting the battery

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 recon-
nected, 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 connecting the bat-
tery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Toyota
dealer.
