4707-2. Steps to take in an emergency
■If “Maintenance Required Visit Your Dealer” is displayed
Indicates that all maintenance is required to correspond to the driven distance
on the maintenance schedule
*.
Comes on approximately 5000 miles (8000 km) after the message has been
reset.
(The indicator will not work properly unless the message has been reset.)
Perform the necessary maintenance. Please reset the message after the
maintenance is performed. (P. 393)
*: Refer to the separate “Scheduled Maintenance Guide” or “Owner’s Manual
Supplement” for the maintenance interval applicable to your vehicle.
■If “Engine Oil Level Low Add or Replace” is displayed
The engine oil level may be low. Check the level of the engine oil, and add
engine oil if necessary. This message may be displayed if the vehicle is
stopped on a slope. Move the vehicle to a level surface and check if the mes-
sage disappears.
■Warning buzzer
P. 461
NOTICE
■If “High Power Consumption Power to Climate Temporarily Limited” is
frequently shown
There is a possible malfunction relating to the charging system or the 12-
volt battery may be deteriorating. Have the vehicle inspected by your Toyota
dealer.
■If “Maintenance Required For Traction Battery At Your Dealer” is
shown
The hybrid battery (traction battery) is scheduled to be inspected or
replaced. Have the vehicle inspected by your Toyota dealer immediately.
●Continuing to drive the vehicle without having the hybrid battery (traction
battery) inspected will cause the hybrid system not to start.
●If the hybrid system does not start, contact your Toyota dealer immedi-
ately.

4907-2. Steps to take in an emergency
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at your Toyota dealer.
●Some systems may require initialization. (P. 535)
■When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact your
Toyota dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
●The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.

4927-2. Steps to take in an emergency
WARNING
■When removing the 12-volt battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts 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.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:
●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 other end of the jumper cable connected to the “+” termi-
nal 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 lighters or allow open flame near
the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the following
precautions when handling the 12-volt battery:
●When working with the 12-volt 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.
●Do not lean over the 12-volt battery.
●In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
●Always wash your hands after handling the 12-volt battery support, termi-
nals, and other 12-volt battery-related parts.
●Do not allow children near the 12-volt battery.
■After recharging the 12-volt battery
Have the 12-volt battery inspected at your Toyota dealer as soon as possi-
ble.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt
battery to emit a malodorous gas, which may be detrimental to the health of
passengers.

When trouble arises
WARNING
■When replacing the 12-volt battery
After replacing, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the replaced 12-volt battery. If not properly installed,
gases (hydrogen) may leak into the vehicle interior, and there is the possi-
ble danger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fan or engine drive belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.
