Special circumstances arise

One thing needs to be clarified

All WABCO systems ECAS

The appearance is consistent

For example, your car has 6×4 eight airbags

The rear axle does not support lifting

The rear lift button will still be retained on the handle

It can be lit up but has no practical effect

The specific function is subject to the vehicle configuration

In fact, this is also a cost reduction and efficiency measure for WABCO, a handle has eaten all over the world, and there is no need to invest in designing more different handles, but can spend more time upgrading key technologies.
