Toyota Yaris: Driving Tips / Driving on Uneven Road
Your vehicle’s suspension and underbody can be damaged if
driven on rough/uneven roads or over speed bumps at excessive speeds. Use care

the tires and wheels can be damaged if driven through potholes or on
rough/uneven roads at excessive speeds. Use care and reduce speed
when traveling on rough/uneven roads or through potholes.
