contact sur face is centred on the head of
the jack. Otherwise, the vehicle could be
damaged and/or the jack could collapse –

block the wheels.
If necessary, place a
chock under the
wheel diagonally opposite the wheel to be
changed.

spare wheel. The wheel is secured by the
conical contact of each bolt.

mph (80 km/h) when
driving with the "space-saver" type spare
wheel fitted.
Visit the dealer network or a
qualified
workshop as soon as possible to have the
tightness of the bolts and the pressure of
the spare wheel checked.
