Instruments
Release the parking brake to switch off the
warning lamp, keeping your foot on the brake
pedal.

fault.
Carry out (2).
Particle filter (Diesel)Fixed.
The particle filter is regenerating itself.
Leave the engine running until the warning lamp

Engine self-diagnostic systemFixed.
A fault with the engine or the EOBD
emissions control system has been detected.
EOBD (European On Board Diagnosis) is a
diagnostics system which complies with, among
others, the standards on emissions limits of:
– CO (carbon monoxide),
– HC (unburnt hydrocarbons),
– NOx (nitrogen oxides), detected by oxygen
sensors placed downstream of the catalytic
converters and
– particles.
Carry out (3) quickly.
Tyre under-inflation detectionFixed.
A tyre is deflated or punctured.
Carry out (1).
Change the wheel or repair the tyre.

Driving
6Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
â–º check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
â–º deactivate the Stop & Start function,
â–º drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
â–º do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
â–º Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
â–º Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
â–º Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
â–º Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

Practical information
7A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
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 while
accelerating. This has no impact on the
vehicle’s behaviour and the environment.
Due to the high exhaust temperatures
caused by the normal operation of the
particle filter, it is recommended not to park
the vehicle on flammable materials (grass, dry
leaves, pine needles, etc.) to avoid any risk of
fire.
Saturation/Regeneration
If there is a risk of clogging, this warning
lamp comes on, accompanied by a
message on the instrument panel display.
This warning is due to the start of saturation of
the particle filter (exceptionally long urban driving
conditions: reduced speed, traffic jams, etc.).
In order to regenerate the filter, it is
recommended to drive as soon as possible -
when traffic conditions and regulations permit
- at a speed of at least 37 mph (60 km/h), with
an engine speed above 2,000 rpm for about
15 minutes (until the warning lamp and/or the
message disappear).
If possible, avoid switching off the engine
before the end of filter regeneration; repeated
interruptions can lead to early deterioration of the
engine oil. It is not recommended to terminate
the filter regeneration with the vehicle stationary.
Malfunction
If this alert persists, do not ignore this warning;
this indicates that a malfunction has occurred in
the exhaust system/particle filter assembly.
Have the assembly checked by a CITROËN
dealer or a qualified workshop.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. 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 the
brake fluid level indicates that the brake pads
are worn.
If this warning lamp comes on, have the
brake pads checked by a CITROËN
dealer or a qualified workshop.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
