CHECKS
CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
I f a l e v e l d r o p s s i g n i fi c a n t l y , h a v e t h e
corresponding system checked by a
CITROËN dealer.
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or
using the dipstick.
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of 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 grade
The oil must be suitable for your en-
gine and conform to the manufacturer's
recommendations. Brake fluid level
T h e b r a k e fl u i d l e v e l s h o u l d b e
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fluid
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Fluid specification
T h e b r a k e fl u i d m u s t c o n f o r m t o t h e
manufacturer's recommendations and
meet the DOT4 standard.
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
ignition off.
O n v e h i c l e s w h i c h a r e fi t t e d w i t h a
p a r t i c l e e m i s s i o n fi l t e r , t h e f a n m a y
operate after the vehicle has been
s w i t c h e d o f f , e v e n i f t h e e n g i n e i s
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.
Fluid specification
The coolant must conform to the manu-
facturer's recommendations.
Screenwash fluid level
Top up the level when necessary.
Fluid specification
For optimum cleaning and to avoid
f r e e z i n g , t h i s fl u i d m u s t n o t b e t o p p e d
up or replaced with water.
Take care when carrying out
checks under the bonnet as
some parts of the engine can be
very hot (risk of burns).
