Maintenance and care
Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ”
mark, etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a
tire.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
Checking tires

2726-3. Do-it-yourself maintenance
YARIS_GRMN_OM_Europe_OM52J40E
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is carried
out approximately every 10000 km
(6000 miles).
■ When to replace your vehicle’s tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage
● A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■ Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
■ Low profile tires
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires on snowy and/or icy roads and drive carefully at a
speed appropriate for road and weather conditions.
■ If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.

Maintenance and care
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
NOTICE
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
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.
■ Low profile tires
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention to
the following:
● Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
● Avoid potholes, uneven pavement, curbs and other road hazards. Failure
to do so may lead to severe tire and wheel damage.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

WARNING
■Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off the
jack, leading to death or serious injury.
● Only use the tire jack that comes with this vehicle for replacing a tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
● Do not raise the vehicle while someone is inside.
● Do not use the tire jack for any purpose other than replacing tires.
● Put the jack properly in its jack point.
● Do not put any part of your body under the vehicle while it is supported by
the jack.
● Do not start the engine or drive the vehicle while the vehicle is supported
by the jack.
● When raising the vehicle, do not put an object on or under the jack.
● Do not raise the vehicle to a height greater than that required to replace
the tire.
● Use a jack stand if it is necessary to get under the vehicle.
● When lowering the vehicle, make sure that there is no-one near the vehi-
cle. If there are people nearby, warn them vocally before lowering.

Maintenance and care
Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and
the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.
WARNING
■ 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 authorized
Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer.
• When installing the wheel nuts, be sure to install them with the tapered
ends facing inward. ( P. 285)
