CHECKING LEVELS
Take care when  working  under  the bonnet, as certain areas of
the
 
engine
 
may
 
be
 
extremely
 
hot
 
(risk

 
of
 
burns)
 
and
 
the
 
cooling
 
fan

 
could
 
start
 
at
 
any
 
time
 
(even
 
with

  the   ignition   off).
The
 
check
 
is
 
carried
 
out
 
either
 
when

 
the

is
 
switched
 
on

 
using

is
 
between

  the   marks   A   and   B.
Check
 
all

 
of

Oil grade
Before
 
topping-up
 
the

oil,
 
check
 
that
 
the
 
oil
 
is
