5 Assemble the jack handle
extension.
6 Raise the vehicle until the tire
is slightly raised off the
ground.
7 Remove all the wheel nuts
and the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.
1 Remove any dirt or foreign
matter from the wheel con-
tact surface.

■Replacing a flat tire
●Do not touch the disc wheels or
the area around the brakes
immediately after the vehicle
has been driven. After the vehi-
cle has been driven the disc
wheels and the area around the
brakes will be extremely hot.
Touching these areas with
hands, feet or oth er body parts
while changing a tire, etc. may
result in burns.
●Failure to follow these precau-
tions could cause the wheel
nuts to loosen and the tire to fall
off, resulting in death or serious
injury.
• Have the wheel nuts tightened
with a torque wrench to 76 ft•lbf
(103 N•m, 10.5 kgf•m) as soon
as possible after changing
wheels.
• Do not attach a heavily dam-
aged wheel ornament, as it may
fly off the wheel while the vehi-
cle is moving.
• When installing a tire, only use wheel nuts that have been spe-
cifically designed for that wheel.
• If there are any cracks or defor- mations in the bolt screws, nut
threads or bolt holes of the
wheel, have the vehicle
inspected by your Toyota
dealer.
• When installing the wheel nuts, be sure to install them with the
tapered ends facing inward.
Installing the spare tire

5068-2. Steps to take in an emergency
COROLLA HV_UIf foreign matter is on the wheel
contact surface,
the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by
hand by approximately the
same amount.
Tighten the whee l nuts until the
tapered portion comes into
loose contact with the disc wheel
seat .
3 Lower the vehicle.
4 Firmly tighten each wheel nut
two or three times in the order shown in the illustra-
tion.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
5
Stow the flat tire, tire jack and
all tools.
■The compact spare tire
●The compact spare tire is identi-
fied by the label “TEMPORARY
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.529)
■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 (vehicles with a tire
pressure warning system)
The tire pressure warning system
must be reset. ( P.447)
■When using the compact spare
tire (vehicles with a tire pres-
sure warning system)
As the compact spare tire is not
equipped with a tire pressure warn-
ing valve and transm itter, low infla-
tion pressure of t he spare tire will
not be indicated by the tire pressure
warning system. Also , if you replace

When trouble arises
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 reinstalling the wheel
ornament (except compact
spare tire)
Align the cutout o f the wheel orna-
ment with the valve stem as shown
in the illustration.

■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 compact 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 with full-speed range
• EPS
• PCS (Pre-Collision System)
• LTA (Lane Tracing Assist)
• Tire pressure warning system (if equipped)
• BSM (Blind Spot Monitor) (if equipped)
• RCTA (Rear Cross Traffic Alert) function (if equipped)
• Rear view monitor system
■Speed limit when using the
compact spare tire
Do not drive at speeds in excess
of 50 mph (80 km /h) when a com-
pact spare tire is installed on the
vehicle.
The compact spare tire is not
designed for driving at high
speeds. Failure to observe this
precaution may lead to an acci-
dent causing death or serious
injury.

would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative perfo rmance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material
of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
