Checking tyre pressures /
inflating accessories


You can also use the compressor, without
injecting any product, to:


- check or adjust the pressure of your tyres,

- inflate other accessories (balls, bicycle
tyres...).
)Turn the selector A
to the "A ir "position.)Uncoil the black pipe Hfully. )Connect the black pipe to the
valve of the wheel or accessory.
If necessary, fit one of the adaptors
supplied with the kit first.

)
Connect the compressor's electricalconnector to the vehicle's 12 V socket. )
Star t the vehicle and let the engine run.)
Adjust the pressure using the compressor (to inflate: switch Bin position "I"; todeflate: switch Bin position "O"
and pressbutton C ), according to the vehicle's tyre
pressure label or the accessory's pressure label.) Remove the kit then stow it.


Should the pressure of one or moretyres be adjusted, it is necessary to reinitialise the tyre pressures (see the "Under-inflation detection" section).

12 V battery
The battery is located under the bonnet.
For access to the (+) terminal: )release the bonnet using the interior lever,
then the exterior safety catch, )raise the bonnet and secure it with its stay, )lift the plastic cover for access to the (+)
terminal.
Access to the battery

Procedure for star ting the engine using another battery or charging a discharged battery.
The presence of this label, in particular with the Stop & Start system, indicatesthe use of a 12 V lead-acid battery withspecial technology and specification;the involvement of a CITROËN dealer or a qualified workshop is essential when replacing or disconnecting the battery.

After refitting the battery, the Stop & Start system will only be active after acontinuous period of immobilisation of thevehicle, a period which depends on theclimatic conditions and the state of chargeof the battery (up to about 8 hours).
When your vehicle's battery is discharged, the engine can be star ted using a slave battery (external or on another vehicle) and jump leadcables.
Starting using another
batter
y
) Connect the red cable to the positive
terminal (+) of the flat battery A, then to the
positive terminal (+) of the slave battery B.) Connect one end of the green or blackcable to the negative terminal (-) of the slave battery B
(or ear th point on the other
vehicle).) Connect the other end of the green or black cable to the ear th point Con the broken
down vehicle (or on the engine mounting). ) Start the engine of the vehicle with the good battery and leave it running for a few minutes.


First check that the slave battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery. Do not try to star t the engine byconnecting a battery charger.
Do not disconnect the (+) terminal when the engine is running.
Before doing any work
Immobilise the vehicle: apply the parking brake, put the gearbox in neutral, then switch off the ignition.Check that all electrical equipment isswitched off.

Practical information
The batteries contain harmful substancessuch as sulphuric acid and lead. They
must be disposed of in accordance with regulations and must not, in anycircumstances, be discarded with household waste. Take used remote control batteries and vehicle batteries to a special collection point.

Protect your eyes and face before handling the battery.
All operations on the battery must becarried out in a well ventilated area andaway from naked flames and sourcesof sparks, so as to avoid the risk of explosion or fire.
Do not try to charge a frozen battery;the battery must first be thawed out to avoid the risk of explosion. If the batteryhas been frozen, before charging have it checked by a CITROËN dealer or aqualified workshop who will check that the internal components have not beendamaged and the casing is not cracked, which could cause a leak of toxic and corrosive acid.
Do not reverse the polarity and use onlya 12 V charger.
Do not disconnect the terminals whilethe engine is running. Do not charge the batteries withoutdisconnecting the terminals first.
Wash your hands afterwards.
It is advisable to disconnect the battery if the vehicle is to be left unused for more than one month.
Do not push the vehicle to star t the engine if you have an electronicgearbox or automatic gearbox.










Charging the battery using
a battery charger
)Disconnect the battery from the vehicle.)Follow the instructions for use provided by
the manufacturer of the charger.)Connect the battery starting with thenegative terminal (-).)Check that the terminals and connectorsare clean. If they are covered with sulphate (whitish or greenish deposit), remove themand clean them.



The Stop & Start battery does not haveto be disconnected for charging.

Driving advice


Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the 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 electricall
y controlled, its cooling capacity is not dependent on the engine speed.
)
To lower the engine speed, reduce your speed.
The maximum towed load on a long incline
depends on the
gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and the
STOPwarning 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.

R
efer to the "Technical data" section for detailsof the weights and towed loads which apply to your vehicle.


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

When not towing a trailer, remove thequickly-detachable tow ball beforedriving.

Checks











Bonnet
Open the left hand front door.


Do not open the bonnet under verywindy conditions.When the engine is hot, handle the exterior safety catch and the stay with care (risk of burns), using the protected area.
)
Lift the safety catch and raise the bonnet.

)Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.

Opening
)Pull the release lever, located at the bottom
of the door aper ture, towards you.
Before doing anything under the bonnet,switch off the Stop & Start system toavoid any risk of injury resulting from anautomatic change to START mode.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.


Closing
)Take the stay out of its suppor t slot. )Clip the stay back into its housing. )Lower the bonnet and release it at the end of its travel. )Pull on the bonnet to check that it haslatched correctly.

Checks























Fuel
Capacity of the tank: approximately 57 litres (petrol) or 55 litres (Diesel).


Low fuel level
Refuelling
When the low fuel level is reached,
this warning lamp in the instrumentpanel comes on, accompanied by anaudible warning, a message and the
last bar of the fuel gauge comes on in orange.
) Take care to select the pump that delivers
the correct type of fuel for your vehicle.) Introduce the nozzle so as to push in themetal non-return flap A.)
Make sure that the nozzle is pushed in as
far as possible before star ting to refuel (risk
of blowback). ) Maintain this position throughout the
refuelling operation.) Push the fuel flap to close it.
If you are filling your tank to the top, do
not persist after the 3rd cut- off; this could cause malfunctions.
A label on the inside of the fuel filler flapreminds you of the type of fuel to use,
depending on your engine type.
Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge. When it
first comes on, about 6 litresof fuel
remain in the tank.
Until sufficient fuel has been added, this warninglamp appears every time the ignition is switched
on, accompanied by an audible warning and amessage. This audible warning and message
are repeated with increasing frequency as the fuel level drops towards "0".
Refuel as soon as possible to avoid running out.
Opening the filler flap may result in an inrush of air. This is entirely normal and results from the
sealing of the fuel system.
) Press the rear edge of the flap to open it
(the filler cap is par t of it).
With Stop & Star t, never refuel with the
system in STOP mode; you must switchoff the ignition with the START/STOP button.

314
Checks
The petrol or Diesel engine of your vehicle is fitted with a catalytic conver ter, a device which helps to reduce the level of harmful emissions
in the exhaust gases.
For petrol en
gines, you must use unleaded fuel.The filler neck is narrower, allowing only
unleaded petrol nozzles to be introduced.
If you have put in the wrong fuel for your vehicle, you must have thefuel tank drained and filled withthe correct fuel before star ting the engine.

Fuel cut- of f

Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of acollision.

Checks

















Misfuel prevention (Diesel) *


Operation

When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remainsclosed and prevents filling.Do not persist but introduce a Diesel type filler nozzle.

*
Depending on country of sale. Mechanical device which prevents fillin
g the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the
wrong fuel.
It remains possible to use a fuel can tofill the tank. In order to ensure a good flow of fuel,do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device and pour slowly.


Travelling abroad

As Diesel fuel pump nozzles may be different in other countries, thepresence of the misfuel prevention device may make refuelling impossible.
Before travelling abroad, werecommend that you check with the CITROËN dealer network, whether your vehicle is suitable for the fuel pumps inthe country in which you want to travel.
