WARNING
■
When removing the battery ter-
minals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal
contacts any metal in the surrounding
area when the positive (+) terminal is
removed, a spark may occur, leading
to a fire in addition to electrical shocks
and death or serious injury.

When removing the battery termi-
nals
When the battery terminals are
removed, the information stored in the
ECU is cleared. Before removing the
battery terminals, contact any author-
ized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■
Avoiding battery fires or explo-
sions
Observe the following precautions to
prevent accidentally igniting the flam-
mable gas that may be emitted from
the battery:
■
Charging the battery
The electricity stored in the battery will
discharge gradually even when the vehi-
cle is not in use, due to natural dis-
charge and the draining effects of
certain electrical appliances. If the vehi-
cle is left for a long time, the battery may
discharge, and the engine may be una-
ble to start. (The battery recharges auto-
matically during driving.)
●
Make sure each jumper cable is
connected to the correct terminal
and that it is not unintentionally in
contact with any other than the
intended terminal.
●
●
■
Do not allow the + and - clamps of
the jumper cables to come into con-
tact with each other.
■
When recharging or replacing the
battery
Do not smoke, use matches, ciga-
rette lighters or allow open flame
near the battery.
●
In some cases, it may not be possible
to unlock the doors using the smart
entry & start system when the battery
is discharged. Use the wireless
remote control or the mechanical key
to lock or unlock the doors.

Battery precautions
The battery contains poisonous and
corrosive acidic electrolyte, while
related parts contain lead and lead
compounds. Observe the following
precautions when handling the bat-
tery:
●
●
The engine may not start on the first
attempt after the battery has
recharged but will start normally after
the second attempt. This is not a mal-
function.
●
When working with the battery,
always wear safety glasses and
take care not to allow any battery
fluids (acid) to come into contact
with skin, clothing or the vehicle
body.
The engine switch mode is memo-
rized by the vehicle. When the battery
is reconnected, the system will return
to the mode it was in before the bat-
tery was discharged. Before discon-
necting the battery, turn the engine
switch off.
●
Do not lean over the battery.
If you are unsure what mode the
engine switch was in before the bat-
tery discharged, be especially careful
