Maintenance and care
YARIS_F_OM_Europe_OM52A54E
■When removing the wheel ornament (vehicles with steel wheels and
emergency tire puncture repair kit)
■When replacing wheels (vehicles with a tire pressure warning system)
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters (except for spare tire [include compact spare tire]) that allow
the tire pressure warning system to provide advance warning in the event of a
loss in tire inflation pressure. Whenever wheels are replaced, tire pressure
warning valves and transmitters must be installed. (P. 510) Remove the wheel ornament using the
wheel cap clip.

Low fuel level warning light
Indicates that remaining fuel is about 5.8 L (1.5 gal.,
1.3 Imp.gal.) or less.
Refuel the vehicle.
*3
Driver’s and front passenger’s seat belt reminder light
(warning buzzer)
Warns the driver and front passenger to fasten their seat
belts.
Fasten the seat belt.
If the passenger’s seat is occupied, the front passen-
ger’s seat belt also needs to be fastened to make the
warning light (warning buzzer) turn off.
*3
(On the center panel)
Rear passengers’ seat belt reminder lights
(warning buzzer) (if equipped)
Warns the rear passengers to fasten their seat belts.
Fasten the seat belt.
Tire pressure warning light (if equipped)
When the light comes on: Low tire inflation pressure such
as
• Natural causes ( P. 588)
• Flat tire ( P. 596, 614)
Adjust the tire inflation pressure to the specified
level.
The light will turn off after a few minutes. In case the
light does not turn off even if the tire inflation pres-
sure is adjusted, have the system checked by any
authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
When the light comes on after blinking for 1 minute:
Malfunction in the tire pressure warning system.
( P. 588)
Have the system checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable
repairer.

■ When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 596, 614
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■ The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (include compact spare tire)
(vehicles with a tire pressure warning system)
The spare tire (include compact spare tire) is not equipped with a tire pres-
sure warning valve and transmitter. If a tire goes flat, the tire pressure warn-
ing light will not turn off even though the flat tire has been replaced with the
spare tire. Replace the spare tire wi th the repaired tire and adjust the tire
inflation pressure. The tire pressure warning light will go off after a few min-
utes.
■ Conditions that the tire pressure warning system may not function prop-
erly (vehicles with tire pressure warning system)
P. 513
■ If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 min-
ute when the engine switch is turned on, have it checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Toyota retailer or Toyota authorized r epairer, or any reliable repairer. The
vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or serious injury.
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■ If the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that you have a flat
tire. Check the tires. If a tire is flat, change it with the spare tire and have
the flat tire repaired by the nearest authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after tire inflat ion pressure adjustment, it is proba-
ble that you have a flat tire. Check the tire s. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit. ( P. 596)
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur (vehicles with a tire
pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly (vehi-
cles with a tire pressure warning system)
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.

YARIS_F_OM_Europe_OM52A54E
If you have a flat tire (vehicles with an
emergency tire puncture repair kit)
Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.) Depending on
the damage, this kit cannot be used to repair the tire. ( P. 598)
After temporarily repairing the tire with the kit, have the tire
repaired or replaced by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. Repairs conducted
using the emergency tire puncture repair kit are only a tempo-
rary measure. Have the tire repaired and replaced as soon as
possible.
WARNING
■ If you have 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, which could result in an accident.

●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P (Multidrive) or N (manual transmission).
● Stop the engine.
● Turn on the emergency flashers. (P. 568)
● Check the degree of the tire damage.
A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.
• Do not remove the nail or
screw from the tire. Remov-
ing the object may widen the
opening and disenable emer-
gency repair with the kit.
• To avoid sealant leakage, move the vehicle until the area of the
puncture, if known, is positioned at the top of the tire.
