Toyota Yaris. Contact Your Toyota Dealer and Have Vehicle Inspected

ABS Warning Light

When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS warning light may illuminate. If this occurs, it is the result of the weak battery and does not indicate an ABS malfunction.
Recharge the battery.
The brake assist system does not operate while the ABS warning light is illuminated.

WARNING

Never tamper with the air bag/pretensioner systems and always have your Toyota dealer perform all servicing and repairs

Self-servicing or tampering with the systems is dangerous. An air bag/pretensioner could accidentally activate or become disabled causing serious injury or death.

If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden maneuvering and braking

If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound is heard, it is dangerous to drive the vehicle at high speeds, or perform sudden maneuvering or braking. Vehicle drivability could worsen and result in an accident.

To determine if you have a slow leak or a flat, pull over to a safe position where you can check the visual condition of the tire and determine if you have enough air to proceed to a place where air may be added and the system monitored again by your Toyota dealer or a tire repair station.

Do not ignore the TPMS Warning Light

Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated. Have the problem taken care of as soon as possible before it develops into a more serious situation that could lead to tire failure and a dangerous accident.

NOTICE

Automatic Transaxle Warning Light

If the automatic transaxle warning light illuminates, the transaxle has an electrical problem. Continuing to drive your Toyota in this condition could cause damage to your transaxle. Consult your Toyota dealer as soon as possible.

KEY Warning Light

If the key warning indicator light illuminates or the push button start indicator light (amber) flashes, the engine may not start. If the engine cannot be started, try starting it using the emergency operation for starting the engine, and have the vehicle inspected at your Toyota dealer as soon as possible.
