●Start the hybrid system with the power
switch in ACC. The hybrid system
may not start with the power switch turned off. Howeve r, the hybrid sys-
tem will operate normally from the
second attempt.
●The power switch mode is recorded
by the vehicle. If the 12-volt battery is reconnected, the vehicle will return
the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the power switch b efore disconnect
the 12-volt battery. Take extra care when connecting the 12-volt battery if
the power switch m ode prior to dis-
charge is unknown.
If the hybrid system will not start even
after multiple attem pts at all methods
above, contact any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
WARNING
■Chemicals in the 12-volt battery
The 12-volt battery contains poison - ous and corrosive sulfuric acid and
may produce hydrogen gas which is
flammable and expl osive. To reduce the risk of death or serious injury, take
the following precautions while work -
ing on or near the 12-volt battery:
●Do not cause sparks by touching
the 12-volt batter y terminals with tools.
●Do not smoke or light a match near the 12-volt battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses
when working near the 12-volt bat- tery.
●Keep children away from the 12-volt battery.
■Where to safely charge the 12-volt battery
Always charge the 12-volt battery in
an open area. Do not charge the 12- volt battery in a garage or closed
room where there is not sufficient
ventilation.
■Emergency measures regarding
electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention. If possible, con-
tinue to apply wate r with a sponge or
cloth while traveling to the nearest
medical facility.
●If electrolyte g ets on your skin
Wash the affec ted area thoroughly. If
you feel pain or burning, get medical
attention immediately.
●If electrolyte gets on your clothes
It can soak through clothing on to
your skin. Immediat ely take off the
clothing and follow the procedure
above if necessary.
●If you accidentally swallow electro -
lyte
Drink a large quantity of water or milk.
Get emergency medical attention
immediately.
■When there is insu fficient 12-volt
battery fluid
Do not use if there is insufficient fluid in the 12-volt battery. There is a pos -
sible danger that the 12-volt battery
may explode.

molded into the sidewall of each tire.
Replace the tires if the treadwear indi -
cators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter -
nal damage.
●A tire goes flat repeatedly or cannot
be properly repaired due to the size or location of a cut or other damage.
If you are not sure, consult with any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 y ears old must be checked by a qualified technician even if
it has seldom or never been used or
damage is not obvious.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of t he tires as snow
tires is lost.
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota re commends that tire
rotation is carried out approximately
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage
to parts of the driv e train as well as
dangerous handling c haracteristics, which may lead to an accident result -
ing in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been
used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
●Vehicles with emergency tire punc -
ture repair kit: Do not tow anything
if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire
may cause unexpec ted damage to the tire.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose sur faces or potholes. These conditions may cause losses in
tire inflation pressure, reducing the
cushioning ability of the tires. In addi - tion, driving on rough roads may
cause damage to the tires them -
selves, as well as the vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue drivi ng, or your tires
and/or wheels may be ruined.

8-2. Steps to take in an emergency
When trouble arises
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 batt ery 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.508
●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 batte ry is disconnected,
as shown in the illustration.
WARNING
■When removing the battery ter -
minals
Always remove the negative (-) termi-
nal first. If the posi tive (+) terminal
contacts any metal in the surrounding area when the positiv e (+) terminal is
removed, a spark m ay occur, leading
to a fire in addition to electrical shocks and death or serious injury.
