Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few pounds off can affect ride quality and
handling.
Do not reduce tire inflation pressure after driving. It is normal for tire infla-
tion pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.

CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury:
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps are lost, replace
them as soon as possible.

The compact spare tire
The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
Make sure to check the tire inflation pressure of the compact spare tire.
(P. 550)
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. Per-
form the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the
vehicle.
Fit tire chains to the front tires.

505 5-2. Steps to take in an emergency
When trouble arises
PRIUS +_OM_OM47821E_(EE)Inflate the tire until the specified
air pressure is reached.
The sealant will be injected
and the pressure will surge,
and then gradually decrease.
The air pressure gauge will
display the actual tire inflation
pressure about 1 minute (15
minutes at low temperature)
after the switch is turned on.

506 5-2. Steps to take in an emergency
PRIUS +_OM_OM47821E_(EE)Inject to specified air pressure.
• Turn the compressor switch off
and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat
the inflation procedure until the
specified tire inflation pressure
is reached.
• If the tire inflation pressure is
still lower than the specified
point after inflation for 35 min-
utes with the switch on, the tire
is too damaged to be repaired.
Turn the compressor switch off
and contact any authorized
Toyota dealer or repairer, or
another duly qualified and
equipped professional.
• If the tire inflation pressure
exceeds the specified air pres-
sure, let out some air to adjust
the tire inflation pressure.
(P. 510, 550)

508 5-2. Steps to take in an emergency
PRIUS +_OM_OM47821E_(EE)Turn the compressor switch on
and wait for an approximately 5
seconds, and then turn it off.
Check the tire inflation pressure.
If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi): The puncture can-
not be repaired. Contact any
authorized Toyota dealer or
repairer, or another duly quali-
fied and equipped profes-
sional.
If the tire inflation pressure is
130 kPa (1.3 kgf/cm
2 or bar,
19 psi) or higher, but less than
the specified air pressure:
Proceed to .
If the tire inflation pressure is the
specified air pressure (
P. 550):
Proceed to .

If the tire is inflated to more than the specified air pressure
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap
from the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and
then turn it off. Check that the air pressure indicator shows the
specified air pressure.
If the air pressure is under the designated pressure, turn the com-
pressor switch on again and repeat the inflation procedure until the
specified air pressure is reached.
The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the valve
should be replaced.
Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly.
STEP 1
Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire valve to let some
air out.STEP 2
