Drive-Off Cycle
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
When the vehicle is first driven off, a humming may be heard or felt by the driver at approximately 25-40 km/h (15-25 mph). This is caused by brief activation of the ABS pump/motor and is a normal function of ABS as part of the self-diagnosis check.
