Access to the spare wheel
The spare wheel is located in the boot under
the floor.
For access to the spare wheel, refer to the
"Access to the tools" section.
Taking out the wheel
Unscrew the central green screw.
Lift the spare wheel towards you from the
rear.
Remove the wheel from the boot.
Putting the spare wheel back in
place
Return the wheel to its housing.
Unscrew the central screw a few turns,
then put it in place in the middle of the
wheel.
Fully tighten the central screw to secure the
wheel correctly.
Practical information
Return the box to its position in the middle
of the wheel.
As the spare wheel is narrower than the
wheels on the vehicle, in the event of a
puncture, the punctured wheel must be
carried in the boot.
