► Unclip the cover by pulling at the top left, then right.► Disengage the cover completely and turn it over,► Take the tweezers from their housing.
Changing  a fuse
Before changing a fuse:► Identify the cause of the fault and fix it.► Stop all power consumption.► Immobilise the vehicle and switch the ignition off.► Identify the defective fuse using the current allocation tables and diagrams.
To replace a fuse, it is essential to:
► Use the special tweezers to extract the fuse from its housing and check the condition of its 
filament.
► Always replace the failed fuse with a fuse of the same rating (same colour); use of a different 
rating may cause malfunctions - risk of fire!
If the fault recurs after replacing a fuse, have the 
electrical system checked by a CITROËN dealer 
or a qualified workshop.
The fuse allocation tables and the 
corresponding diagrams are available 
from a CITROËN dealer or from a qualified 
workshop.
The replacement of a fuse not shown in  the allocation tables may cause a serious 
malfunction of your vehicle. Contact a 
CITROËN dealer or a qualified workshop.

Starting using another 
battery
When your vehicle's battery is discharged, the 
engine can be started using a backup battery 
(external or from another vehicle) and jump 
leads or a battery booster.
Never try to start the engine by 
connecting a battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the backup battery 
has a nominal voltage of 12 V and a capacity 
at least equal to that of the discharged 
battery.
The two vehicles must not be in contact with 
each other.
Switch off all the electrical consumers on both 
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close 
to moving parts of the engine (fan, belts, etc.).
Do not disconnect the (+) terminal while the 
engine is running.
 
 
► Lift the plastic cover on the (+) terminal, if your vehicle has one.► Connect the red cable to the positive terminal (+) of flat battery  A (at the metal elbow) then to 
the positive terminal (+) of backup battery  B or 
the booster.
► Connect one end of the green or black cable to the negative terminal (-) of backup battery  B 
or the booster (or an earth point on the other 
vehicle).
► Connect the other end of the green or black cable to earth point  C on the broken down 
vehicle.
► Start the engine of the vehicle with the good battery and leave it running for a few minutes.► Operate the starter on the broken down vehicle and let the engine run.
If the engine does not start straight away, switch 
off the ignition and wait a few moments before 
trying again.
► Wait until the engine returns to idle then disconnect the jump lead cables in the reverse 
order.

the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal 
 
► Raise the lever A fully to release the clamp 
B.
► Remove the clamp B by lifting it off.
Reconnecting the (+) terminal
 
 
► Raise the lever A fully.► Refit the open clamp B on the (+) terminal.► Push the clamp B fully down.► Lower the lever A to lock the clamp B.
Do not force the lever as locking will not 
be possible if the clamp is not positioned 
correctly; start the procedure again.
Following reconnection of the battery
After reconnecting the battery, turn on the 
ignition and wait 1 minute before starting the 
engine, in order to enable the electronic systems 
to initialise.
For right-hand drive vehicles, when the 
total distance recorder has reached 37 
miles (60 km), it is necessary to wait approx. 
15 minutes before starting the engine.
However, if minor problems persist following 
this operation, contact a CITROËN dealer or a 
qualified workshop.
Referring to the corresponding section, you must 
yourself reinitialise or reset certain systems, 
such as:
– the key with remote control or electronic key (depending on version),– the sunroof and its electric blind,– the electric windows,– the date and time,– the 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 of 
immobilisation of the vehicle, a period which 
depends on the exterior temperature and the 
state of charge of the battery (up to about 8 
hours).

Towing
Procedure for having your vehicle towed or for towing another vehicle using the towing eye.
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 towbar; ropes 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 recovery 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.

Technical data
Engine technical data and 
towed loads
Engines
The engine specifications (capacity, max. power, 
max. speed, energy, CO
2 emissions, etc.) 
associated with your vehicle are indicated on 
the registration document, as well as in sales 
brochures.
These characteristics correspond to the values 
type-approved on a test bed, under conditions 
defined in 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 
your 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 values and the towed loads listed are 
valid for a maximum altitude of 1,000 metres. 
The towed load must be reduced by steps of 
10% for each additional 1,000 metres.
The maximum authorised nose weight 
corresponds to the weight permitted on the 
towball.
GTW: Gross train weight.
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, limit the 
towed weight.
Towing using a lightly loaded vehicle can  adversely affect roadholding.
Braking distances are increased when towing 
a trailer.
When using a vehicle to tow, never exceed a 
speed of approximately 60 mph (100 km/h) 
(observe the local legislation in force).
If the exterior temperature is high, it is 
recommended that the engine is allowed 
to idle for 1 to 2 minutes after the vehicle 
comes to a stop, to facilitate its cooling.
