Maintenance and care

■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 (vehicles with 165/60R15 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 or tire chains 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.
Your vehicle is equipped with a tire pressure warning system.
While the vehicle is in motion, the system monitors the fluctuations in
the wheel speed signals that are output by the speed sensor for the
brake control system.
It informs the driver if it detects a low tire inflation pressure.
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized when
changing the tire
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■The initialization operation
●Make sure to carry out initialization after adjusting the tire infla-
tion pressure. Also, make sure the tires are cold before carrying
out initialization or tire inflation pressure adjustment.
●If you accidentally press the reset switch when initialization is not
necessary, adjust the tire inflation pressure to the specified level
when the tires are cold, and conduct initialization again.
Tire pressure warning system (if equipped)

4528-2. Steps to take in an emergency
AYGO_OM_Europe_OM9A012E
PCS warning light (if equipped)
When the warning light flashes (and a buzzer sounds):
Indicates a malfunction in the PCS (Pre-Collision system)
 Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable
repairer immediately.
When the warning light illuminates:
Indicates that the PCS (Pre-Collision system) is temporar-
ily unavailable, possibly due to either of the following:
• The part of the windshield around the front sensor being
dirty, fogged up or covered with condensation, ice, stick-
ers, etc.
 Clear the dirt, fog, condensation, ice, stickers, etc.
( P. 249)
• Front sensor temperature being outside of its opera-
tional range
 Wait for a while until the area around the front sensor
has cooled down sufficiently.
Either the VSC system or PCS (Pre-Collision system) is
disabled or both are disabled.
 To enable the PCS, enable both the VSC system and
PCS. ( P. 254, 280)

When trouble arises
AYGO_OM_Europe_OM9A012E
■To prevent the clutch from overheating (vehicles with a multi-mode man-
ual transmission)
● Do not use the accelerator pedal or starting assist system to hold the vehicle
on a hill.
● On an uphill incline, observe the following whenever possible:
• Maintain a safe distance from the vehicle ahead and avoid unnecessary
starting off and stopping.
• Avoid using E mode on an uphill slope. This will help to avoid unneces-
sary gear changes.
■ Front passenger detection sensor, seat belt reminder and warning
buzzer
● If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■ If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empt y, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer as soon
as possible.
■ Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.
■ When the tire pressure warning light comes on (vehicles with the tire
pressure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 459, 481
If the tire is not punctured:
Check the tire inflation pressure after the tire temperature has lowered suffi-
ciently. Adjust the inflation pressure to the appropriate level and carry out ini-
tialization. ( P. 4 0 6 )
■ The tire pressure warning light may come on due to natural causes
(vehicles with the 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 is at the specified level and
carry out initialization. ( P. 406)
