BONNET (2/2)
Closing the bonnet
Check that nothing has been left in the
engine compartment.
To close the bonnet again, hold the
bonnet in the middle and guide it down,
allowing a 30 cm gap before it is closed,
then release it. It will latch automatically
under its own weight.
Ensure that the bonnet is
properly locked.
Check that nothing is pre-
venting the catch from lock-
ing (gravel, cloth, etc.).
After carrying out any work
in the engine compart-
ment, check that nothing
has been left behind (cloth,
tools, etc.).
These may damage the engine or
cause a fire.
In the event of even a slight
impact involving the radia-
tor grille or bonnet, have the
bonnet lock checked by an
authorised dealer as soon as pos-
sible.

the linings become worn, but it should
never drop below the “MINI” warning
line.

cedure from our network or from the
