WARNING
■ Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur which
could lead to an accident resulting in death or serious injury:
● Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated tires
● Air leaking from between tire and wheel
● Wheel deformation and/or tire damage
● Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■ When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

■ Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Toyota Service Booklet” or “Toyota Warranty Booklet”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.

5-2. Steps to take in an emergency
When trouble arises
VERSO_EE_OM64517E
■ If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning light system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
● If tires not equipped with tire pressure warning valves and transmitters
are used
● If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer
● If the tire inflation pressure is 380 kPa (3.9 kgf/cm2 or bar, 55 psi) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
● If electronic devices or facilities using similar radio wave frequencies are
nearby
● If a radio set at a similar frequency is in use in the vehicle
● If a window tint that affects the radio wave signals is installed
● If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings
● If non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
● If tire chains are used
■ If the tire pressure warning light frequently comes on after blinking for
1 minute (vehicles with a tire pressure warning light system)
If the tire pressure warning light frequently comes on after blinking for 1 min-
ute when the engine switch (vehicles without smart entry & start system) or
the “ENGINE START STOP” switch (vehicles with smart entry & start sys-
tem) is turned on, have it checked by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

5-2. Steps to take in an emergency
VERSO_EE_OM64517E
WARNING
■ Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
● Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
● If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 130 kPa (1.3
kgf/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■ When performing an emergency repair
● A tire should only be repaired with the emergency tire puncture repair kit if
the damage is caused by a sharp object such as nail or screw passing
through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergenc y repair with the repair kit.
● The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
● 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.
