Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
Your CITROËN technician resets the
indicator to zero after each service.
However, if you do your own servicing,
the procedure for resetting to zero is
as follows :

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,


switch on the ignition; the distance re-
corder display begins a countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the fl ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is confi rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by the fl ashing of

"OIL--" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to lo-
cate the dipstick and the oil fi ller cap
on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count.
