of the handle go from red to green to indicate

  5•  Adjust the height of the support leg by 
pressing down the inner catch until it touches 
the car floor (it is important for the leg to be

Base 0+1 K” can remain in the car ready for 
use.
  •  If your car has storage compartments on the 
floor of the vehicle, in the area where the support 
leg is to rest, you should open the compartment 
and rest the leg on the bottom of it.
