Reactivation
In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that the
sensors may be dirty.
When the speed of the vehicle is
below about 6 mph (10 km/h), some
sources of noise (motorcycle, lorry,
pneumatic drill, ...) may trigger the
audible parking sensor signals.

 Press button A again, the warn-
ing lamp switches off, the system
is reactivated.
"HYDRACTIVE III +" ELECTRONIC SUSPENSION
The suspension automatically and
instantly adjusts to different driving
styles and to the profi le of the road,
providing the best compromise be-
tween occupant comfort and vehicle
road holding.
The system alternates between soft
and fi rm suspension settings, maxi-
mising comfort at the same time as
constantly ensuring the highest level
of safety. It also automatically cor-
rects ride height, according to the
vehicle load and driving conditions.
In addition, the "Hydractive III +" sys-
tem allows you to choose between
two modes of suspension.
A change of suspension mode can
be made either when the vehicle is
moving or when stationary, by press-
ing button A . Display on the instrument
panel
The suspension mode selected is
displayed on the instrument panel
screen.
Normal mode
This mode favours soft
damping for maximum com-
fort.
If the speed authorised for a
particular position is exceed-
ed, the vehicle reverts automatically
to the normal road position.
SPORT mode
This mode favours dynamic
driving.
The warning lamp on but-
ton A comes on in addition
to the message on the in-
strument panel screen.

SPORT mode is retained when you
switch off the engine.

For use on diffi cult roads when tra-
velling at reduced speed, as well as

Position changes may only be
made when the engine is running.
The adjustable ground clearance
meets all types of situation. Apart
from a few specifi c situations, the
vehicle should be in the Normal po-
sition.

Position not authorised
The instrument panel screen tempo-
rarily displays a message indicating
that this position is not authorised.
The vehicle remains in the autho-
rised position and the instrument
panel screen indicates this position
to you.
Automatic variation of ground clea-
rance
- If your speed exceeds 70 mph (approx. 110 km/h), on a good
road surface, ground clearance
is lowered. The vehicle returns
to its normal position if the road
surface deteriorates or if your
speed is lower than 55 mph (ap-
prox. 90 km/h).
- At low or medium speed, if the road surface is poor, ground
clearance is increased. The ve-
hicle returns to its normal posi-
tion as soon as conditions allow.
- On switching off the ignition, the ground clearance is reduced to
the parking position

For your safety if you are operat-ing underneath the vehicle, you
must support the vehicle with
axle stands.

Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's
recommendations. Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and meet the DOT4 standard.
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.
Check this level also between each
scheduled service and before long
journeys. 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 reli-
ability of the engine and emis-sion control system, the use
of additives in the engine oil is
prohibited. Power steering fluid or power
steering and suspension
fluid level
This fl uid must be topped up
by a CITROËN dealer.
Dipstick
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, us-
ing the type of oil suited
to your engine.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
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
(refer to the “Engines” section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesirable
odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the instrument
panel display, accompanied by an
audible signal and lighting of the
service warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.).
To regenerate the fi lter, it is advised to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for this
component.
