Stop
& Start
Before doing anything under the bonnet,
you must switch off the ignition to avoid any
risk of injury resulting from an automatic
change to START mode.

The
location of the interior bonnet release
lever prevents the bonnet being opened
when the left-hand front door is closed.
When
the engine is hot, handle the
exterior safety catch and the bonnet stay
with care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
Cooling of the engine
when stopped
The engine cooling fan may start after the
engine has been switched off.
Take care with objects or clothing that could
be caught in the blades of the fan!
