Do not start the engine at any time while the
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or a door or the
boot lid is opened or closed).
Raising the vehicle
Prevent the vehicle from rolling away
using chocks or similar.
On a level road:
Place chocks in front of and behind
the wheel which is diagonally oppo-
site the wheel you wish to change.
On uphill gradients:
Place chocks behind both wheels
on the other axle.
