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).
Oil level
The check of the level is done with
the dipstick, located under the
bonnet. Refer to the description of
your engine compartment for the
position of the dipstick.Engine oil change
Refer to the manufacturer's service schedule
for details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Oil specification
The oil must be the correct grade for your
engine and conform to the manufacturer's
recommendations.
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum
If the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.
B = minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check will only be correct if the vehicle is
on level ground and the engine has been off for
more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
After topping up the oil, the check when
switching on the ignition with the oil level
indicator in the instrument panel is not valid
during the 30 minutes after topping up.

Checking components
12 V battery
Electrolyte level
For access to the 12 V Battery, refer
to the corresponding section. Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once
a
month.
When carrying out work on the 12 V Battery,
refer to the corresponding section for
details of the precautions to be taken before
disconnecting the battery and following its
reconnection.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary
.
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
