IIS328DQ Threshold Settings

For IIS328DQ, if the threshold is set to 0.25g, does this mean that it will interrupt if either X, Y, or Z changes more than 0.25g? Our application is to detect a vehicle is moving or not. What is the best threshold to set for this application?

Lsm6ds3: I'm working on Fifo functionality of Lsm6ds3 for z-axis but when i retrieve values I'm getting higher g values of 2g at steady state. Can somebody explain why such higher values are generated.

I'm using FIFO in continuous mode and when i read from LSM6DS3_ACC_GYRO_FIFO_DATA_OUT_H register most of the times I'm getting constant value of 0x0F from this register at steady state. The values generated at steady state are 2g always.
