NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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 and 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
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation 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.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 586)

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 reinstall the tire valve caps.
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 have been 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 only in an emergency.
Make sure to check the tire inflation pressure of the compact spare tire.
(P. 586)
If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on the rear of the vehicle. Perform 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.

Before performing emergency repair
Check the degree of the tire
damage.
• Do not remove the nail or
screw from the tire. Removing
the object may widen the
opening and prevent emer-
gency repair with the repair kit.
• Type A: To avoid sealant leak-
age, move the vehicle until the
area of the puncture, if known,
is positioned at the top of the
tire.

Taking out the emergency tire puncture repair kit
Open the rear deck board. (P. 387)
Take out the emergency tire puncture repair kit. (P. 521)
In the following cases, the tire cannot be repaired with the emergency
tire puncture repair kit. Contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
When the tire is damaged due to driving without sufficient air pressure
When there are any cracks or damage at any location on the tire, such as
on the side wall, except the tread
When the tire is visibly separated from the wheel
When the cut or damage to the tread is 4 mm (0.16 in.) long or more
When the wheel is damaged
When two or more tires have been punctured
When more than 2 sharp objects such as nails or screws have passed
through the tread on a single tire
When the sealant has expired

VERSO_WE_OM64550E_EURO5Turn the switch OFF when the pressure gauge connected to
the hose reads the specified pressure.
If the inflation pressure is not attained within 5 minutes, emergency
repair is not possible due to severe damage. Contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
After completely filling the tire with air, disconnect the hose
from the valve on the tire.
Pull the power plug of the compressor out of the power outlet
on the vehicle.
To spread the liquid sealant evenly in the tire, immediately
drive for about 5 km (3 miles) or 10 minutes.
After driving about 5 km (3 miles)
or 10 minutes, pull your vehicle
over in a safe place and recon-
nect the compressor.
Read the inflation pressure on
the pressure gauge.
