Practical 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
the axle and the nose wei
ght 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 by 10 % for every1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply toyour vehicle.
Side wind
)
Take into account the increased sensitivityto side wind.

Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y 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 en
gine 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 engine
braking is recommended.


Tyres
)
Check the tyre pressures of the towing
vehicle 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 lon
g incline
depends on the gradient and the ambienttemperature.
In all cases, keep a check on the coolant
temperature.

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 using the dipstick.

Engine oil change

Refer to the ser vicing booklet for the inter val for
this operation.
In order to maintain the reliabilit
y 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 services. CITROËNrecommends that you check the oil level, and top up if necessary, every3 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.

Checks
Coolant level
The coolant level should be close
to the "MA X" mark but should never exceed it. When the engine is warm,
the temperature of the coolant is regulated bythe fan. This can operate with the ignition off.
On vehicles which are fitted with a par ticle
emission filter, the fan ma
y operate after
the vehicle has been switched off, even if
the en
gine is cold.

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 en
gine cold,
to check the level. Th
e brake fluid level should be closeto 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.

Screenwash / headlamp
wash fluid level
To check the level or top up the fluid on vehicle
fitted with headlamp washers, immobilise the
vehicle and switch of the en
gine. )Open the bonnet and secure it with
the stay. )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 of 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, for which the
involvement of a CITROËN dealer or a qualified
workshop is required when replacing or
disconnecting the battery.
Failure to obser ve this recommendation may
shor ten the life of the battery.12 V battery
The battery does not require any
maintenance.
However, check that the terminals
are clean and correctly tightened,
particularl
y in summer and winter.
When carrying out work on the battery, refer to
the "Practical information" section for details of
the precautions to be taken before disconnectingthe 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

Refer to the ser vicing booklet for
details of the replacement intervals
for these components.
Dependin
g 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 compar tment filter mayhave an adverse effect on the performance
of the air conditioning system and generate undesirable odours.
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.

6-speed electronic
gearbox
The gearbox does not require anymaintenance (no oil change).
Refer to the ser vicing booklet for
details of the checking interval for
this component.
Brake wear depends on the st
yle
of driving, par ticularly in the case
of vehicles used in town, over shor tdistances. It may be necessary
to have the condition of the brakes checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in
th
e brake fluid level indicates that the brakepads are worn.















Brake pads
