2023 TOYOTA COROLLA HYBRID warning light

4047-2. Steps to take in an emergency
USE ONLY” on the tire sidewall.
Use the compact spare tire tempo-
rarily, and only in an emergency.
●Make sure to check the tire infla-
tion pressure of the compact
spare tire. (P.426)
■When the compact spare tire is
equipped
The vehicle becomes lower when
driving with the compact spare tire
compared to when driving with stan-
dard tires.
■After completing the tire
change
The tire pressure warning system
must be reset. ( P.333)
■When using the compact spare
tire
As the compact sp are tire is not
equipped with a tire pressure warn-
ing valve and transmitter, low infla-
tion pressure of the spar e tire will
not be indicated by the tire pressure
warning system. Also, if you replace
the compact spare tire after the tire
pressure warning light comes on,
the light remains on.
■If you have a flat front tire on a
road covered with snow or ice
Install the compact spare tire on one
of the rear wheels of the vehicle.
Perform the following steps and fit
tire chains to the front tires:
1 Replace a rear tire with the com-
pact spare tire.
2 Replace the flat front tire with the
tire removed from the rear of the
vehicle.
3 Fit tire chains to the front tires.
■When reinstallin g the wheel cap
(steel wheels except compact
spare tire)
Align the cutout of the wheel cap
with the valve stem as shown in the
illustration.
WARNING
■When using the compact
spare tire
●Remember that the compact
spare tire provided is specifi-
cally designed for use with your
vehicle. Do not use your com-
pact spare tire on another vehi-
cle.
●Do not use more than one com-
pact spare tires simultaneously.
●Replace the comp act spare tire
with a standard tire as soon as
possible.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
■When the compact spare tire
is attached
The vehicle speed may not be
correctly detected, and the follow-
ing systems may not operate cor-
rectly:
• ABS & Brake assist
• VSC
• TRAC
• Automatic High Beam
• Dynamic radar cruise control
• EPS
• PCS (Pre-Collision System)
• LDA (Lane Departure Alert)

4127-2. Steps to take in an emergency
■To prevent 12-volt battery dis-
charge
●Turn off the headlights and the
audio system while the hybrid sys-
tem is off.
●Turn off any unnecessary electri-
cal 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 you r Toyota dealer.
●Some systems may require initial-
ization. (P.452)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals
are removed, the information stored
in the ECU is cleared. Before
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt
battery will discharge gradually even
when the vehicle is not in use, due
to natural discharge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the hybrid system may
be unable to start. (The 12-volt bat-
tery recharges aut omatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery (vehicles
with a smart key system)
●In some cases, it may not be pos-
sible 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 att empt 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 memo-
rized by the vehicle. When the
12-volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
■When replacing t
he 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Use a 12-volt battery that the case
size is same as the previous one
(LN1), 20 hour rate capacity
(20HR) is equivalent (45Ah) or
greater, and per formance rating
(CCA) is equivalent (295A) or
greater.
• If the sizes differ, the 12-volt bat-
tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time p eriod where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and the hybrid system may not be
able to start.
●For details, cons ult your Toyota
dealer.
WARNING
■When removing the 12-volt
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, leading to a fire
in addition to ele ctrical shocks
and death or serious injury.

When trouble arises
WARNING
■Avoiding 12-volt battery fires
or explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the 12-volt 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 lighters or allow open
flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poi-
sonous and corrosi ve acidic elec-
trolyte, 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 bat-
tery.
●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 sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow children near the
12-volt battery.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fans, etc.
