behind the wheel that is diagonally 
opposite to the wheel being changed.
When changing wheel on a hill:
Place chocks on the downhill side 
blocking both wheels of the other axle.
Warning!
G
The dimensions of the Minispare wheel are 
different from those of the road wheels. As 
a result, the vehicle handling characteristics 
change when driving with a Minispare wheel 
mounted.
The spare wheel should only be used 
temporarily, and replaced with a regular 
road wheel as quick as possible.
