Vauxhall 2010 Astra Owner's Manual page 62

Secure both bicycle wheels to wheel
recesses using strap retainers.
Check the bicycle to make sure it is
secure.
The settings for the wheel recesses
and on the rotary lever on the pedal
crank recess should be noted and
saved for each bicycle. Correct
presetting will facilitate refitting of the
bicycle.
Removing a bicycle from the rear

bearing mount to remove it.
Retracting the rear carrier system
Push the pedal crank mounts into the
pedal crank recess.
Storage

tightly downwards as far as possible.
