2023 TOYOTA RAV4 PLUG-IN HYBRID warning

5768-2. Steps to take in an emergency
operate properly ( P.572). This is not
a malfunction, as the hybrid system will start normally on the second attempt.
●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 bat- tery, 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 reconnecting the 12-volt
battery.
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to
European regulations.
●Use a 12-volt battery that the case
size is same as the previous one (LN2), 20 hours rate capacity (20HR) is equivalent (55Ah) or greater, and
performance rating (CCA) is equiva- lent (345A) or greater.• If the sizes differ, the 12-volt battery
cannot be properly secured. • If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the 12- volt battery may discharge and hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●When removing the 12-volt battery:  P.486
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery. • Use the exhaust hose that was attached to the 12-volt battery before
replacing and confirm that it is firmly connected to the hole section of the vehicle.
• Use the exhaust hole plug included with the new 12-volt battery or the one installed on the battery prior to the
replacement. (Depending on the new
12-volt battery installed, the exhaust hole may be plugged.)
For details, consult any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

●The terminals can be connected to the body side when the negative terminal
of the 12-volt battery is disconnected, as shown in the illustration.
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 trouble arises
WARNING
■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 “+”
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 con- tact with each other.
●Do not smoke, use matches, ciga-rette lighters or allow open flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poison-
ous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the follow-
ing precautions when handling the 12-volt battery:
●When working with the 12-volt bat-
tery, always wear safety glasses and take care not to allow any bat-tery fluids (acid) to come into con-
tact 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 atten-
tion. Place a wet sponge or cloth over the affected area until medical
attention can be received.
●Always wash your hands after han- dling the 12-volt battery support, terminals, and other battery-related
parts.
●Do not allow children near the 12-
volt battery.
■After recharging the 12-volt bat-
tery
Have the 12-volt battery inspected at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer as soon as possible.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 replacing the 12-volt bat-
tery
●For information regarding 12-volt battery replacement, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●After replacing, securely attach the exhaust hose and exhaust hole
plug to the exhaust hole of the replaced 12-volt battery. If not prop-erly installed, gases (hydrogen)
may leak into the vehicle interior, and there is the possible danger of the gas igniting and exploding.

5788-2. Steps to take in an emergency
■If the high coolant temperature
warning light comes on,
flashes or “Engine Coolant
Temp High Stop in a Safe
Place See Owner’s Manual” is
shown on the multi-informa-
tion display

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under
the hood, do not open the hood until the steam has subsided. The engine compartment may be very
hot.
●After the hybrid system has been
turned off, check that the “READY” indicator is off.When the hybrid system is operat-
ing, the gasoline engine may auto- matically start, or the cooling fan may suddenly operate even if the
gasoline engine stops. Do not touch or approach rotating parts such as the fan, which may lead to fingers
or clothing (especially a tie, a scarf or a muffler) getting caught, result-ing in serious injury.
●Do not loosen the coolant reservoir cap while the hybrid system and
radiator are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power con-trol unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool coolant to a hot hybrid
system too quickly can cause dam- age to the hybrid system.
■To prevent damage to the cool-ing system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust, etc.).
●Do not use any coolant additive.
