Particle filter (Diesel)
The start of saturation of the 
particle filter is indicated by 
the temporary illumination of this warning lamp 
accompanied by a message in the multifunction 
screen.
As soon as the traffic conditions permit, regenerate 
the filter by driving at a speed 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.
For more information on checking levels, refer to 
the corresponding section.
On a new vehicle, the first particle 
filter regeneration operations may be 
accompanied by a "burning" smell, 
which is per fectly 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.
Checks
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.
Air filter and passenger compartment filter
Refer to the manufacturer's 
service schedule for details of the 
replacement intervals for these 
components.
Oil filter
Replace the oil filter each time the 
engine oil is changed.
Refer to the manufacturer's 
service schedule for details of 
the replacement interval for this 
component.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
When carrying out work on the battery, refer 
to the "12 V battery" section for details of the 
precautions to be taken before disconnecting 
the battery and following its reconnection.
Depending on the environment (e.g. dusty 
atmosphere) and the use of the vehicle 
(e.g.
 
city driving), replace them twice as often 
if necessary .
A clogged passenger compartment filter may 
have an adverse effect on the per formance 
of the air conditioning system and generate 
undesirable odours.

In the event of a fault with the the SCR emissions control system
A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions control 
system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.You have exceeded the authorised 
driving limit: the starting prevention 
system inhibits engine starting.
If it is a temporary fault, the alert 
disappears during the next journey, 
after self-diagnosis of the SCR system.
The UREA, SERVICE and diagnostic warning 
lamps comes on, accompanied by an audible 
signal and the display of the message 
"Emissions fault".
The alert is triggered when driving when the 
fault is detected for the first time, then when 
switching on the ignition for subsequent 
journeys, while the fault persists. In the event of the detection of a fault
If a fault with the SCR system is confirmed (after 
30
  miles (50 km) covered with the permanent display 
of the message signalling a fault), the SERVICE and 
engine diagnostic warning lamps come on and the 
UREA warning lamp flashes, accompanied by an 
audible signal and the display of a message (e.g.: 
"Emissions fault: Starting prevented in 150 miles") 
indicating the remaining range express in miles or 
kilometres.
While driving, the message is displayed every 
30
  seconds while the fault with the SCR system 
persists.
The alert is repeated when switching on the ignition.
You should go to a CITROËN dealer or a qualified 
workshop as soon as possible.
Other wise, you will not be able to restart your engine.
During an authorised driving phase (between 
650 miles and 0 miles) (1 100 km and 0 km)
Every time the ignition is switched on, the 
SERVICE and engine diagnostic warning 
lamps come on and the UREA warning lamp 
flashes, accompanied by an audible signal and 
the display of the message "Emissions fault: 
Starting prevented". Starting prevented
To be able to start the engine, you must call on 
a CITROËN dealer or a qualified workshop.

Charging the battery using 
a battery charger
F Follow the instructions for use provided by the manufacturer of the charger. Protect your eyes and face before 
handling the battery.
All operations on the battery must be 
carried out in a well ventilated area 
away from naked flames and sources 
of sparks, so as to avoid the risk of 
explosion and fire.
Do not try to charge a frozen battery; 
the battery must first be thawed out to 
avoid the risk of explosion. If the battery 
has been frozen, before charging have 
it checked by a CITROËN dealer or a 
qualified workshop who will check that 
the internal components have not been 
damaged and the casing is not cracked, 
which could cause a leak of toxic and 
corrosive acid.
Do not reverse the polarity and use only 
a 12 V charger.
Do not disconnect the terminals while 
the engine is running.
Do not charge the batteries without 
disconnecting the terminals first.
Wash your hands after wards.
Batteries contain harmful substances such 
as sulphuric acid and lead. They must be 
disposed of in accordance with regulations 
and must not, in any circumstances, be 
discarded with household waste.
Take used remote control batteries and 
vehicle batteries to a special collection 
point.

Towing a trailer, ...
Driving advice
Cooling
Towing 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.
F 
T
 o 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.
Side wind
F Take into account the increased sensitivity  to side wind.
F If the warning lamp and the STOP  
warning lamp come on, stop the 
vehicle and switch off the engine 
as soon as possible.
Towbar suitable for the attachment of a trailer or installation of a bicycle carrier, with additional lighting and signalling.
Distribution of loads
F Distribute the load in the trailer so that the  heaviest 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 by 10
  % for every 1   000 metres of 
altitude.
We recommend the use of genuine 
CITROËN towbars and their harnesses 
that have been tested and approved 
from the design stage of your vehicle, 
and that the fitting of the towbar is 
entrusted to a CITROËN dealer or a 
qualified workshop.
If the towbar is not fitted by a CITROËN 
dealer, it is imperative that it is 
fitted in accordance with the vehicle 
manufacturer's instructions.
Driving with a trailer places greater demands 
on the towing vehicle and the driver must take 
particular care. Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Refer to the "Technical data" section for details 
of the weights and towed loads which apply to 
your vehicle.

Fitting roof bars
To fit longitudinal and/or transverse roof bars, visit your CITROËN dealer or a qualified workshop.Maximum authorised weight on the roof rack: 60 kg.
If the height exceeds 40 cm, adapt the speed of the vehicle to the profile of the road to avoid 
damaging the roof bars and the fixings on the roof.
Be sure to refer to national legislation in order to comply with the regulations for transporting 
objects which are longer than the vehicle.
Braking
Towing 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.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the 
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be 
deactivated automatically if a genuine 
CITROËN towbar is used.
