Checks

Checking levels
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.
Engine oil level
It is normal to top up the oil level between two   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).
The
  check   is   carried   out   either   when  
t

he   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.
To   ensure   that   the   reading   is   correct,  
y

our   vehicle   must   be   parked   on   a   level  
s

ur face   with   the   engine   having   been   off  
f

or   more   than   30   minutes.
Take   care   when   working   under   the  
b

onnet,   as   certain   areas   of   the   engine  
m

ay   be   extremely   hot   (risk   of   burns)  
a

nd   the   cooling   fan   could   start   at   any  
t

ime   (even   with   the   ignition   off).
Checking using the dipstick

.
Oil grade
Before topping-up the oil or changing the oil, c
heck   that   the   oil   is   the   correct   grade   for   your  
e

Refer to the manufacturer's service schedule for   details   of   the   interval   for   this   operation.
Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations.
The
  brake   fluid   level   should   be   close  
t

o   the   "MA X"   mark.   If   it   is   not,   check
