Checking and topping up fluids
A WARNING
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- For safety reasons the bonnet must always
be completely closed when the vehicle is

moving.
After closing it always check that it
is properly secured. It should not be possi­
ble to
lift
the front edges of the bonnet.
Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet properly, otherwise it could cause an
accident.
