Checking levels
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.
Engine oil level
Checking using
the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
It
  is   normal   to   top   up   the   oil   level   between  
t

wo   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   kms).A
