In the event of a breakdown

Reconnecting the (+) terminal

 

 

►  Raise lever 

A

 fully.

►  Refit open clamp 

B

 on the 

(+)

 terminal.

►  Push clamp 

B

 fully down.

►  Lower lever 

A

 to lock clamp 

B

.

►  Depending on equipment, lower the plastic 

cover on the 

(+)

 terminal.

Do not force the lever when pressing on 

it, as if the clamp is not positioned 

correctly, locking will then not be possible. 

Start the procedure again.

Following reconnection

After reconnecting the battery, turn on the 

ignition and wait 1 minute before starting the 

engine, to enable the electronic systems to 

initialise.

If minor problems nevertheless persist following 

this operation, contact a CITROËN dealer or a 

qualified workshop.

Referring to the relevant section, reinitialise 

certain equipment:

–  Remote control key or electronic key 

(depending on version).

– Sunroof.

–  Electric windows.

–  Date and time.

–  Preset radio stations.

The Stop & Start system may not be 

operational during the trip following the 

first engine start.

In this case, the system will only be available 

again after a continuous period with the 

vehicle immobilised, the duration of which 

depends on the exterior temperature and the 

state of charge of the battery (up to about 8 

hours).

Towing the vehicle

General recommendations

Observe the legislation in force in the 

country where you are driving.

Ensure that the weight of the towing vehicle is 

higher than that of the towed vehicle.

The driver must remain at the wheel of the 

towed vehicle and must have a valid driving 

licence.

When towing a vehicle with all four wheels on 

the ground, always use an approved towing 

arm; rope and straps are prohibited.

The towing vehicle must move off gently.

When the vehicle is towed with its engine 

off, there is no longer braking and steering 

assistance.

A professional towing service must be 

called if:

–  Broken down on a motorway or main road.

–  Not possible to put the gearbox into neutral, 

unlock the steering, or release the parking 

brake.

–  Not possible to tow a vehicle with an 

automatic gearbox, with the engine running.

–  Towing with only two wheels on the ground.

–  Four-wheel drive vehicle.

–  No approved towbar available.

Before towing the vehicle, it is essential 

to put the vehicle in free-wheeling mode.

For more information on 

Free-wheeling

, refer 

to the corresponding section.

Electric motor

An electric vehicle cannot under any 

circumstances be used to tow another 

vehicle.

However, it may be used, for example, to exit 

a rut.

For more information on accessing the 

Tool kit

, 

refer to the corresponding section.

Towing your vehicle

section.

►  Release the cover downwards.

To be towed:

►  Screw the towing eye in fully.

►  Install the towbar.

►  Put the gearbox into neutral.

Failure to observe this instruction could 

result in damage to certain components 

(braking, transmission, etc.) and to the 

absence of braking assistance the next time 

the engine is started.

Automatic gearbox

Never tow the vehicle with the driving 

wheels on the ground and the engine off.

►  Unlock the steering and release the parking 

brake.

180

In the event of a breakdown

Engine technical data and 

towed loads

Engines

The engine characteristics are given in the 

vehicle's registration document, as well as in 

sales brochures.

Only the values available at the time of 

publication are presented in the tables.

Contact a CITROËN dealer or a qualified 

workshop to obtain missing values.

The maximum power corresponds to the 

value type-approved on a test bed, under 

conditions defined by European legislation 

(Directive 1999/99/EC).

For more information, contact a CITROËN dealer 

or a qualified workshop.

Weights and towed loads

The weights and towed loads relating to 

the vehicle are indicated on the registration 

document, as well as in sales brochures.

These values are also indicated on the 

manufacturer's plate or label.

For more information, contact a CITROËN dealer 

or a qualified workshop.

The GTW (Gross Train Weight) and towed load 

values indicated are valid up to a maximum 

altitude of 1,000 metres. The towed load value 

must be reduced by 10% for each additional 

1,000 metres of altitude.

The maximum authorised nose weight 

corresponds to the weight permitted on the 

towball.

When exterior temperatures are high, the 

vehicle performance may be limited in 

order to protect the engine. When the exterior 

temperature is higher than 37°C, reduce the 

towed weight.

Towing even with a lightly loaded vehicle 

can adversely affect its road holding.

Braking distances are increased when towing 

a trailer.

When using a vehicle to tow, never exceed 

a speed of 62 mph (100 km/h) (observe the 

local legislation in force).

hub.

The system builds playlists (in temporary 

memory); this operation can take from a 

few seconds to several minutes at the first 

connection.

Playlists are updated whenever a USB memory 

stick is connected or the contents of a particular 

USB memory stick are changed. The lists 

are memorised: if they are not modified, the 

subsequent loading time will be shorter.

Auxiliary (AUX) jack socket

Depending on equipment

Connect a portable device (MP3 player, 

etc.) to the auxiliary jack socket using an 

audio cable (not supplied).

This source is only available if "

Aux

smartphone.

The Bluetooth profile must be activated, first 

adjust the volume on the portable device (to a 

high level).

Then adjust the volume of the system.

If play does not start automatically, it may be 

necessary to start the audio playback from the 

smartphone.

Control is from the portable device or by using 

the system's touch buttons.

classification structured in the form of a 

library.

The default classification used is by artist. To 

modify the classification used, return to the

Information and advice

The system supports USB mass storage 

devices, BlackBerry

®

 devices or Apple

®

 players 

via the USB ports. The adapter cable is not 

supplied.

Devices are managed using the audio system 

controls.

Other devices, not recognised on connection, 

must be connected to the auxiliary socket using 

a jack cable (not supplied) or via Bluetooth 

streaming, if compatible.

To protect the system, do not use a USB 

hub.

The audio system will only play audio files with 

".wav", ".wma", ".aac", ".mp3", ".mp4", ".m4a", 

".flac", ".ogg" file extensions and with a bit rate 

of between 32 Kbps and 320 Kbps (300 Kbps 

maximum for ".flac" files).

It also supports VBR (Variable Bit Rate) mode.

All ".wma" files must be standard WMA 9 files.

The supported sampling rates are 11, 22, 44 and 

48 KHz.

To avoid reading and display problems, we 

recommend choosing file names less than 20 

characters long that do not contain any special 

characters (e.g. “ ? . ; ù).

Use only USB memory sticks in FAT or FAT32 

format (File Allocation Table).

We recommend using the original USB 

cable for the portable device.

Telephone

Pairing a Bluetooth

®

 

telephone

Up to 10 phones can be paired to the system.

used (from the telephone or from the system), 

ensure that the code is the same in the system 

and in the telephone.

The services available depend on the 

network, the SIM card and the 

compatibility of the Bluetooth devices used. 

Check for services availability in the phone's 

manual and with the operator.

The profiles compatible with the system 

are: HFP, OPP, PBAP, DID, A2DP, 

AVRCP, SPP and PAN.

Go to the Brand's website for more information

Frequently asked 

questions

The following information groups together the 

answers to the most frequently asked questions 

concerning the system.

Radio

The reception quality of the tuned radio 

station gradually deteriorates or the station 

presets are not working (no sound, 87.5 MHz 

is displayed, etc.).

The vehicle is too far from the selected station’s 

transmitter, or no transmitter is present in the 

geographical area.

►  Activate the "RDS" function in the upper bar 

to enable the system to check whether there is 

a more powerful transmitter in the geographical 

area.

The environment (hills, buildings, tunnels, 

basement car parks, etc.) is blocking reception, 

including in RDS mode.

This is a perfectly normal phenomenon, and is 

not indicative of an audio system malfunction.

The aerial is missing or has been damaged 

(for example while entering a car wash or 

underground car park).

►  Have the aerial checked by a dealer.
