Hold the jack 4 horizontally, setting its head always at the height of the booster 1 as close as possible to the corresponding wheel, as indicated by arrow 2.
Start turning the jack by hand to properly set the jack foot (it should go under the car a little).
Make several turns of the handle until the wheel is off the ground. Turn out bolts and remove a wheel. Put the spare wheel on the hub and turn it until the mounting holes of the hub and the wheel match.
If bolts are included with the spare wheel, use them only to secure it.
Tighten the screws, making sure the wheel is correctly positioned on the hub, and lower the jack.
After lowering the jack, tighten the bolts firmly (tightening torque: 110 Nm).
Wheel bolts
If you are using security wheel bolts, install them as close to the tire valves as possible (otherwise, the wheel cover may not fit properly).
