CHECKS

CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signiﬁ cantly, have the corre-
sponding system checked by a CITROËN
dealer or a qualiﬁ ed workshop.

When working under the bon-
net, take care, as certain areas
of the engine may be extremely
hot (risk of burns).

The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the igni-
tion is switched on using the oil level indicator
in the instrument panel, or using the dipstick.

Oil level

Engine oil change
Refer to the Maintenance and Warranty
Guide for the interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.

Oil speciﬁ cation
The oil must correspond to your engine
and conform to the manufacturer's rec-
ommendations.

Brake fluid level

The brake ﬂ uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the ﬂ uid
Refer to the Maintenance and Warranty
Guide for the interval for this operation.

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

Power steering fluid level

The power steering ﬂ uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.
Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the igni-
tion off.

On vehicles which are ﬁ tted with a par-
ticle emission ﬁ lter, the fan may oper-
ate after the vehicle has been switched
off, even if the engine is cold.

In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant
The coolant does not have to be
changed.

Coolant speciﬁ cation
The coolant must conform to the manu-
facturer's recommendations.
