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.

BONNET
Opening

At the front of the bonnet, lift the
safety catch B and raise the bonnet.

 Unclip the stay C from its hous-
ing and pivot it to insert it in the
notch D indicated by a yellow
arrow.

 Fix the stay in the notch to hold
the bonnet open. Closing

 Take the stay out of the support
notch.

 Clip the stay in its housing.

 Lower the bonnet then slam it
fi rmly at the end of its travel.

 Pull on the bonnet to check that
it is fully closed.
When the engine is hot, handle the
safety catch and bonnet stay with
care (risk of burns).
The location of the interior release
lever prevents opening of the bon-
net while the left hand front door is
closed.
This operation must only be carried
out when the vehicle is stationary.
Avoid opening the bonnet in strong
winds.

 Open the left hand front door.

 Pull the interior bonnet release
lever A , located at the bottom of
the door frame.
Before doing anything under
the bonnet, switch off the Stop & Start system to avoid any risk
of injury resulting from an automat-
ic change to START mode.

RUNNING OUT OF FUEL (DIESEL)
HDi 110 engine

 Unclip the protective cover to gain
access to the priming pump. HDi 140 and HDi 160 engines

 Unclip the protective cover to gain
access to the priming pump.
Priming the fuel system
In the event of running out of fuel:

 after fi lling (minimum 5 litres)
and removing the protective cover,
operate the manual priming pump,
until some resistance is felt,

 operate the starter motor while
depressing the accelerator pedal
slightly until the engine starts. HDi engines make use of ad-
vanced technology.
All maintenance and repairs require
special qualifi cations which only a
CITROËN dealer can guarantee.
V6 HDi 240 engine with electric
pump
In the event of running out of fuel:

 after adding fuel, turn the ignition
key to position M , wait for a few
seconds,

 operate the starter motor until
the engine starts.
If the engine fails to start after sev-
eral attempts, contact a CITROËN
dealer.
If the engine fails to start at the fi rst
attempt, wait fi fteen seconds before
trying again.
If the engine fails to start after a
few attempts, operate the priming
pump again and then try to start the
engine.
When the engine is idling, accelerate
slightly to complete the bleeding of
the circuit.

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 en-
gine and conform to the manufac-
turer'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 regular-
ly. 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.
Take care when doing anything un-
der the bonnet, as some parts of the
engine can be extremely hot (risk of
burns). 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 exceed
this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.

Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up or replaced with water.
Reservoir capacities:
-
screenwash: approximately 3.5 litres,
- screenwash and headlamp wash: approximately 6.15 litres. Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.

Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or fl u-
ids into sewers or onto the
ground.
Take used oil to a CITROËN dealer
(France) or an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible sig-
nal and a message on the multifunc-
tion screen.
Top up the level when you stop the
vehicle.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations. The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine 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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
