4While raising, secure the tire,
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,
repeat step 2 and step 4.
6 Repeat step5, any time the
tire is lowered or disturbed.
7 Stow the tools and jack
securely.
■The temporary spare tire
●The temporary spare tire is identi-
fied by the “TEMPORARY USE
ONLY” marking on the disc wheel
and/or tire sidewall.
Use the temporary spare tire tem-
porarily, and only in an emer-
gency.
●Make sure to check the tire infla-
tion pressure of the temporary spare tire. (
P.547)
■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
Install the temporary spare tire on
one of the front w heels of the vehi-
cle. Perform the following steps and
fit tire chains to the rear tires:
1 Replace a front tire with the tem-
porary spare tire.
2 Replace the flat rear tire with the
tire removed from the front of the
vehicle.
3 Fit tire chains to the rear tires.
WARNING
■When using the temporary
spare tire
●Remember that t he temporary
spare tire provided is specifi-
cally designed for use with your
vehicle. Do not use your tempo-
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

When trouble arises
6 Start the hybrid system to
check that the radiator cool-
ing fan operates and to check
for coolant leaks from the
radiator or hoses.
7 If the fan is not operating:
Stop the hybrid system
immediately and contact your
Toyota dealer.
If the fan is operating:
Have the vehicle inspected at
the nearest Toyota dealer.
8 Check if “Engine Coolant
Temp High Stop in a Safe
Place See Owner’s Manual”
is shown on the multi-infor-
mation display.
If the message does not disappear:
Stop the hybrid system and contact
your Toyota dealer.
If the message is not displayed:
Have the vehicle i nspected at the
nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●After the hybrid system has
been turned off , check that the
“READY” indicator is off. When
the hybrid system is operating,
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, resulting
in serious injury.
●Do not loosen the coolant reser-
voir caps, while the hybrid sys-
tem and radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding coolant
Add coolant slowly after the
hybrid system has cooled down
sufficiently. Adding cool coolant to
a hot hybrid system too quickly
can cause damage to the hybrid
system.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust, etc.,).
●Do not use any coolant additive.

satisfy the following grade and
viscosity.

SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
