Drive-Off Cycle
WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. 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 on the ICU and is a normal function of ABS as the system is performing a diagnosis check.
