Pass the buckle through the wheel as shown in the figure and
secure it so that the buckle does not contact the wheel.
Pass the belt through the
buckle, then pull the belt end to
secure the flat tire.
Return the rear seatback on the right side of the rear seatback to its
original position.
Remove the tire blocks and store the tools and jack.
Check the inflation pressure.
Refer to Tires on P. 560.
Have the flat tire repaired or replaced as soon as possible.
●Do not press the tire pressure monito ring system set switch after install-
ing the spare tire. The switch is only to be pressed after installing the
repaired flat tire or inst alling a replacement tire ( →P. 148).

WARNING
■Make sure the mounting surfaces of the wheel, hub and lug nuts
are clean before changing or replacing tires
When changing or replacing a tire, not removing dirt and grime from the
mounting surfaces of the wheel, hub and hub bolts is dangerous. The
lug nuts could loosen while driving a nd cause the tire to come off, result-
ing in an accident.
■Do not apply oil or grease to lug nuts and bolts and do not tighten
the lug nuts beyond the recommended tightening torque
Applying oil or grease to lug nuts and bolts is dangerous. The lug nuts
could loosen while driving and cause the tire to come off, resulting in an
accident. In addition, lug nuts and bolts could be damaged if tightened
more than necessary.
■Always securely and correctly tighten the lug nuts
Improperly or loosely tightened lug nuts are dangerous. The wheel
could wobble or come off. This could result in loss of vehicle control and
cause a serious accident.
■Be sure to reinstall the same nuts you removed or replace them
with metric nuts of the same configuration
Because the wheel studs and lug nuts on your Toyota have metric
threads, using a non-metric nut is dan gerous. On a metric stud, it would
not secure the wheel and would damage the stud, which could cause
the wheel to slip off and cause an accident.
■Do not drive with any tires that have incorrect air pressure
Driving on tires with incorrect air pressure is dangerous. Tires with
incorrect pressure could affect handling and result in an accident. When
you check the regular tires’ air pressure, check the spare tire, too.

If Trouble Arises
WARNING
■Never tamper with the air bag/pretensioner systems and always have
your Toyota dealer perform all servicing and repairs
Self-servicing or tampering with the systems is dangerous. An air bag/pre-
tensioner could accidentally activate or become disabled causing serious
injury or death.
■
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, decrease
vehicle speed immediately and avoid sudden maneuvering and
braking
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden maneuvering
or braking. Vehicle driv ability could worsen and re sult in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position
where you can check the visual condition of the tire and determine if you
have enough air to proceed to a place where air may be added and the
system monitored again by your Toyota dealer or a tire repair station.
■Do not ignore the TPMS Warning Light
Ignoring the TPMS warning light is da ngerous, even if you know why it
is illuminated. Have th e problem taken care of as soon as possible
before it develops into a more serious situation that could lead to tire
failure and a dangerous accident.
NOTICE
■ Automatic Transaxle Warning Light
If the automatic transaxle warning light illuminates, the transaxle has an
electrical problem. Continuing to drive your Toyota in this condition could
cause damage to your transaxle. Consult your Toyota dealer as soon as
possible.
■ KEY Warning Light
If the key warning indicator light illuminates or the push button start indicator
light (amber) flashes, the engine may not start. If the engine cannot be
started, try starting it using the emergency operation for starting the engine,
and have the vehicle inspected at your Toyota dealer as soon as possible.

If Trouble Arises
■Tire Pressure Monitoring System Warning Light
●
Perform tire pressure adjustment wh en the tires are cold. Tire pressure
will vary according to the tire temperature, therefore let the vehicle stand
for 1 hour or only drive it 1 mile (1.6 km) or less before adjusting the tire
pressures. When pressure is adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may turn on after the tires cool
and pressure drops below specification.
Also, an illuminated TPMS warning ligh t, resulting from the tire air pres-
sure dropping due to cold ambient temperature will remain illuminated
even if the ambient temper ature rises. In this case, it will also be neces-
sary to adjust the tire air pressures. If the TPMS warning light illuminates
due to a drop in tire air pressure, make sure to check and adjust the tire
air pressures.
●Tires lose air naturally over time and the TPMS cannot tell if the tires are
getting too soft over time or you have a flat. However, when you find one
low tire in a set of four-that is an indication of trouble; you should have
someone drive the vehicle slowly forward so you can inspect any low
tire for cuts and any metal objects sticking through tread or sidewall. Put
a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be address ed by more than simply reinflating
the tire as leaks are dangerous - take it to your Toyota dealer.

If the driver’s door is opened while the ignition is switched to ACC, a
continuous beep sound will be heard to notify th e driver that the igni-
tion has not been switched off (STOP). Left in this condition, the key-
less entry system will not operate, the car cannot be locked, and the
battery power will be depleted.
A beep sound will be hear d 6 times and the KEY warning light (red)
will flash continuously if the ignition has not been switched off, all the
doors are closed, and the key is remo ved from the vehicle. This is to
notify the driver that the key has been removed from the vehicle and
the ignition has not been switched off.
Because the key utilizes low-intensity radio waves, the Key Removed From
Vehicle Warning may activate if the key is carried together with a metal object
or it is placed in a poor signal reception area.
The warning beep sound will be heard for about 3 seconds when
there is any abnormality in tire inflation pressures (→P. 218).
If there is the possibility of a collis ion with a vehicle ahead, the beep
sounds continuously and a warning is indicated in the display.
If the power steering system has a malfunction, the power steering
malfunction light turns on or flashes and the buzzer operates at the
same time.
Refer to Warning/Indicator Lights on P. 156.
