CHECKING LEVELS

















Oil level


Oil specifi cation
The oil must be the correct grade
for your engine and conform to the
manufacturer's recommendations.










Brake fl uid level

Changing the fl uid
Refer to the servicing booklet for de-
tails of the interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and meet the DOT4 standard.


The check is carried out ei-
ther when the ignition is
switched on using the oil lev-
el indicator on the instrument
panel, or using the dipstick.
This manual check will only be cor-
rect 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 lev-
el between two services (or oil
changes). CITROËN recommends
that you check the level, and top
up if necessary, every 3 000 miles
(5 000 kms). The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

Take care when working
under the bonnet, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).











Power steering fl uid level
The power steering fl uid
level should be close to the
"MAX" mark. With the en-
gine cold, unscrew the cap
to check the level.
If a level drops signifi cantly, have
the corresponding system checked
by a CITROËN dealer or a qualifi ed
workshop.
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.

Engine oil change
Refer to the servicing booklet for de-
tails of the interval for this operation. After topping up the oil, the check
when switching on the ignition with
the oil level indicator in the instru-
ment panel is not valid during the
30 minutes after topping up.
