Maintenance and care
YARIS_F(including HV)_WE_52E26E
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.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of
handling control.
Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width and inset*.
Replacement wheels are available at any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions (if equipped)
Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
Be careful not to damage the aluminum wheels when using
tire chains.
Use only Toyota genuine balance weights or equivalent and
use a plastic or rubber hammer when balancing your wheels.

CAUTION
Replacing a flat tire
Do not touch the disc wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or
other body parts while changing a tire, etc. may result in burns.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 103 N·m (10.5
kgf·m, 76 ft·lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped
professional.
• When installing the wheel nuts, be sure to install them with the tapered
ends facing inward. (P. 497)
NOTICE
Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Be careful when driving over bumps with the compact spare tire
installed on the vehicle
The vehicle becomes lower when driving with the compact spare tire com-
pared to when driving with standard tires. Be careful when driving over
uneven road surfaces.
Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving per-
formance.

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.
• To avoid sealant leakage,
move the vehicle until the area
of the puncture, if known, is
positioned at the top of the
tire.
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

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.
Emergency tire puncture repair kit
The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant has been used
and needs to be replaced, purchase a new bottle at any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped profes-
sional. The compressor is reusable.
The sealant can be used when the outside temperature is from -30°C
(-22°F) to 60°C (140°F).
The repair kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than
the original ones, or for any other purposes.
The sealant has a limited lifespan. The expiry date is marked on the bot-
tle. The bottle of sealant should be replaced with a new bottle before the
expiry date. Contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional for replacement.
If the sealant gets on your clothes, it may stain.
If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
Do not use to check or to adjust the tire pressure.

causing death or serious injury.
Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident causing death or serious injury.
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
When fixing the flat tire
Stop your vehicle in a safe and flat area.
Do not touch the wheels or the area around the brakes immediately after
the vehicle has been driven.
