has lowered sufficiently, check
the inflation pressure of each tire
and adjust them to the specified
level.
2 If the warning light does not turn
off even after several minutes
have elapsed, check that the
inflation pressure of each tire is
at the specified level and perform
initialization. ( P.584)
■The tire pressure warning light
may come on due to natural
causes (vehicles with tire pres-
sure warning system)

6528-2. Steps to take in an emergency
■Starting the engine when the
battery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the
audio system while the engine is
stopped.
(Vehicles with Stop & Start system:
Except when the engine is stopped
due to the Stop & Start system)
●Turn off any unnec essary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the battery is removed or
discharged
●Information stor ed in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at your Toyota dealer.
●Some systems may require initial-
ization. ( P.696)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
the ECU is cleared . Before remov-
ing the battery terminals, contact
your Toyota dealer.
■Charging the battery
The electricity stor ed in the battery
will discharge gradu ally even when
the vehicle is not i n use, due to nat-
ural discharge and the draining
effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine ma y be unable to
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing
the battery (vehicles without
smart key start system)
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 malfunction.
■When recharging or replacing
the battery (vehicles with smart
key system)
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●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 malfunction.
●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 dis-
charged. Before disconnecting the
battery, turn the engine switch to
OFF.
If you are unsure what mode the
engine switch wa s in before the
battery discharged, be especially
careful when reconnecting the
battery.
■When the battery is removed or
discharged (vehicles with Stop
& Start system)
The Stop & Start system may not
automatically stop the engine for up
to an hour.
■When replacing the battery
●Vehicles with Stop & Start system:
Use a genuine battery specifically
designed for use with the Stop &
Start system or a battery with equiv-
alent specifications to a genuine
battery. If an unsup ported battery is
used, Stop & Start system functions
may be restricted to protect the bat-
tery. Also, battery performance may
decrease and the engine may not
be able to restart. Contact your
Toyota dealer for details.

• If the sizes differ, the battery can- not be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the battery may discharge and
engine may not be able to start.
WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighter s or allow open
flame near the battery.
■Battery precautions
