227Practical information

We recommend the use of genuine
CITROËN towbars and their harnesses that have been tested and approvedfrom the design stage of your vehicle,and that the fitting of the towbar is
entrusted to a CITROËN dealer or aqualified workshop.
If the towbar is not fitted by a CITROËN dealer, it is imperative that it isfitted in accordance with the vehiclemanufacturer's instructions.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so that the
heaviest items are as close as possible to
t
he axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Side wind
)
Take into account the increased sensitivity
to side wind.

Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the
fan is electrically controlled, its cooling capacity is not dependent on the engine speed. )
To lower the engine speed, reduce your speed.
)If the warning lamp and the STOP
warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.



The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.



Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
The maximum towed load on a long incline depends on the gradient and the ambient
tem
perature.
In all cases, keep a check on the coolant
temperature.

of the weights and towed loads which apply toyour vehicle.

repeatedly until fuel appears in the
transparent pipe.
) Tighten the bleed screw.)
Operate the star ter until the engine star ts (if the engine fails to star t at the first
attempt, wait around 15 seconds before
trying again).) If the engine fails to star t after a few
attempts, operate the priming pump again,
th
en the starter.) Put the style cover back in position and clip it in place, ensuring that it has clippedcorrectly. )
Close the bonnet.

2 litre HDi engine


If the engine does not star t first time, don't keep trying. Star t the procedure
again from the beginning.

Before doing anything under the bonnet, switch off the ignition ( Readylamp off)to avoid any risk of injury resulting from automatic operation of the engine.

Checking levels Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

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


Oil level

The reading will only be correct if the
vehicle is on level ground and theengine has been off for more than30 minutes.
The check is carried out either when the ignition
is switched on using the oil level indicator in the
instrument panel, or usin
g the dipstick.
Engine oil change

Refer to the ser vicing booklet for the inter val 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 engineand conform to the manufacturer's
recommendations.
It is normal to top up the oil level between two ser vices. CITROËNrecommends that you check the oil level, and top up if necessary,every 3 000 miles (5 000 kilometres).
Before doing anything under the bonnet,switch off the ignition (Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.

239Checks
Coolant level
The coolant level should be closeto the "MA X" mark but should never exceed it.


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


Coolant specifi cation

The coolant must conform to the
manufacturer's recommendations.

Power steering fluid
level
The power steering fluid level should
be close to the "MA X" mark. Unscrew
the cap, with the engine cold,
to check the level. Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Brake fluid level


Changing the fl uid

Refer to the ser vicing booklet for the inter val for
this operation.

Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet the
DOT4 standard.
In addition, as the cooling system ispressurised, wait at least one hour after
switching off the engine before carrying out any work. To avoid any risk of scalding, unscrewthe cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and topup the level. When the en
gine is warm, the temperature of
the coolant is regulated by the fan. This can
operate with the ignition off.
On vehicles which are fitted with a particle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold
.

fitted with headlamp washers, immobilise the
vehicle and switch of the en
gine. )Before opening the bonnet, ensure that the
engine has completely stopped. )Open the screenwash reser voir filler cap.

To p p i ng up

This additive must be topped up by a CITROËN
dealer or a qualified workshop without delay.

Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is
indicated by illumination of
the ser vice warning lamp,
accompanied by an audible
warning and a message in the instrument panelscreen.

Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or
replaced by plain water.

Checks
Unless otherwise indicated, check these
components in accordance with the servicing
booklet and according to your engine.
Other wise, have them checked by a CITROËN
dealer or a qualified workshop.
Before doing anything under the bonnet, switch off the ignition ( Readylamp off)to avoid any risk of injury resulting from automatic operation of the engine.The presence o
f this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement of a CITROËN dealer or a qualified workshop is essential when replacing or disconnecting the
battery.
12 V battery
The battery does not require any maintenance. However, check that the terminals
are clean and correctly tightened,
particularly in summer and winter.
When carr
ying out work on the battery, refer
to the "Practical information" section for
details of the precautions to be taken before
disconnectin
g the battery and following its reconnection.

Particle emission filter (Diesel)
The start of saturation of theparticle filter is indicated bythe temporary illumination of
this warning lamp accompanied by a message
in the multi-function screen.
As soon as the traffic conditions permit, regenerate the filter by driving at aspeed of at least 40 mph (60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this indicates a low additive level.


On a new vehicle, the first par ticlefilter regeneration operations may be accompanied by a "burning" smell, which is perfectly normal.
Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances,notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
The 100% electric mode is not available during regeneration of the par ticle emissions filter.
Air filter and passenger compartment filter
Oil filter

Replace the oil filter each time the engine oil is changed.
Refer to the ser vicing booklet for
details of the replacement interval for
this component.
Re
fer to the ser vicing booklet for
details of the replacement intervals
for these components.
Dependin
g on the environment (e.g. dustyatmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary.y A clogged passenger compartment filter mayhave an adverse effect on the performance
of the air conditioning system and generate undesirable odours.
