Auto hold Stops your car accidentally rolling back if you stop on a hill
Auto Hold is an extension of our electronic parking brake system. It stops your car from accidentally rolling backwards when you're stationary, or setting off on a hill. That means you won't need to keep applying the parking brake manually, check whether you've applied enough braking pressure, or worry about rolling back as you prepare to move off.
It's convenient, more comfortable, and safer in situations where your car needs to be kept stationary with the engine running - in slow moving traffic, for example.
The system is operated via the ABS/ESP hydraulic unit. When you brake your car to a stop, Auto Hold keeps the braking pressure you last applied. You can take your foot off the brake pedal and all four wheel brakes will stay on.
If the ABS wheel speed sensors detect any rolling, the braking force is automatically increased until your car comes to a standstill again. This may be the case if, for example, you brake gently to a stop on a hill. As soon as you press the accelerator again and, in the case of manual gearboxes, release the clutch, Auto Hold reduces the braking pressure again.
