taking care that the tire goes
straight up without catching
on any surrounding part, to
prevent it from flying forward
during a collision or sudden
braking.
Tightening torque:
34.7 ft•lbf (46.6 N•m, 4.8 kgf•m)
5Confirm it is not loose after
tightening:
1 Push and pull the tire
2 Try rotating
Visually check to ensure tire is not
hung on surrounding parts.
If looseness or misassembly exists,

porarily, and only in an emer-
gency.
●Make sure to check the tire infla-
tion pressure of the temporary spare tire. (

■When using the temporary
spare tire
As the temporary spare tire is not
equipped with the tire pressure
warning valve and transmitter, low
inflation pressure of the spare tire
will not be indicated by the tire pres-
sure warning system. Also, if you
replace the temporary spare tire
after the tire pressure warning light
comes on, the light remains on.
■If you have a flat rear tire on a
road covered with snow or ice

rary spare tire on another vehi-
cle.
●Do not use more than one tem-
porary spare tires simultane-
ously.
●Replace the temporary spare
tire with a standa rd tire as soon
as possible.

When trouble arises
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, l eading 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
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 12-volt 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 1 2-volt 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.
■After recharging the 12-volt
battery
Have the 12-volt battery
inspected at your Toyota dealer
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 detrimenta l to the health
of passengers.
■When replacing the 12-volt
battery
●For information regarding 12-
volt battery rep lacement, con-
tact your Toyota dealer.
