Maintenance and care
The OBD system determines
that a problem exists some-
where in the emission control
system. Your vehicle may not
pass the I/M test and may need
to be repaired. Contact your
Toyota dealer to service the
vehicle.
When the 12-volt battery is dis-
connected or discharged
Readiness codes that are set
during ordinary driving are
erased.
Also, depending on your driving
habits, the readiness codes may
not be completely set. The error code in the OBD sys-
tem will not be cleared unless
the vehicle is driven 40 or more
times.
Contact your Toyota dealer to
prepare the vehicle for re-test-
ing.
Emission inspection
and mainte
nance (I/M)
programs
Some states have vehicle
emission inspection pro-
grams which include OBD
(On Board Diagnostics)
checks. The OBD system
monitors the operation of
the emission control sys-
tem.
If the malfunc tion indica-
tor lamp comes on
Your vehicle may not pass
the I/M test in the follow-
ing situations:
When the malfunction
indicator lamp still
remains on after several
driving trips
If your vehicle does not
pass the I/M test

Owners Manual_USA_M42C01_en
Use only Toyota wheel bolts
and wrenches designed for
use with your aluminum
wheels.
 When rotating, repairing or
changing your tires, check
that the wheel bolts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels. 1
Turn the power switch off.
Confirm that the charging connec-
tor is not connected. Also, do not
use the Remote Air Conditioning
System during the procedure.
2Open the front passenger’s
door.
By keeping the door open, unex-
pected operation of the Remote Air
Conditioning System can be pre-
vent. ( P.409)

handle and remove the
panel.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.

NOTICE
●Do not put the repair kit directly
onto dusty ground such as sand
at the side of the road. If the
repair kit vacuums up dust, etc.,
a malfunction may occur.
●Make sure the sealant bottle of
the repair kit is in a vertical posi-
tion. The repair kit does not
operate properly when it is laid.
■Precautions for the emer-
gency tire puncture repair kit
●The repair kit power source
should be 12 V DC suitable for
vehicle use. Do not connect the
repair kit to any other source.
●Place the repair kit in a storage
to prevent it from being exposed
to dirt or water.
●Store the repair kit in the lug-
gage compartment out of reach
of children.
●Do not disassemble or modify
the repair kit. Do not subject
parts such as the air pressure
indicator to impacts. This may
cause a malfunction.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repaired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer or other qualified service
shop as soon as possible. After
use of liquid sealant, make sure to
replace the tire pressure warning
valve and transmitter when repair-
ing or replacing the tire. ( P.476)

not star t
Reasons for the EV system
not starting vary depending
on the situation. Check the
following and perform the

Vehicle specifications
tion on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
■DOT quality grades
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.
For example: Treadwear 200 Trac-
tion AA Temperature A
■Treadwear
The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.
For example, a tire graded 150
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
