anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See

whatever road conditions will permit. If the STABILITY
SYSTEM ACTIVE message comes on, you will know that
something has caused your vehicle to start to spin, so
you should consider slowing down.Tire Pressure Status – 144:If you see the CHECK
