INSTRUMENTS and CONTROLS
When the engine is running or the vehi-
cle is moving, the lighting of one of the
following warning lights indicates the
occurrence of a fault requiring interven-
tion on the part of the driver.
Central alert.
Lighting is associated with
the displaying of another
warning light:
- braking,
- power steering,
- engine oil pressure,
- coolant temperature,
stop the vehicle as soon as it is safe to
do so. Service.
If this comes on, it indicates
the occurrence of a problem
in one of the systems which
does not have a specifi c
warning light.
In order to identify it, consult the mes-
sage on the multifunction display.
Check:
- the engine oil level,
- the screenwash fl uid level,
- the remote control battery,
- the condition of the bulbs.
For any other situations, contact a
CITROËN dealer.
The illumination of this warning light
may also indicate that the (Diesel) par-
ticle fi lter is starting to get clogged up,
due to specifi c extended urban driving
conditions: low speed, congestion, etc.
In order to regenerate the fi lter, you are
advised to drive, once traffi c conditions
allow, at a speed of 40 mph (60 km/h)
or above for at least 5 minutes (until the
warning light goes out). Braking.
If this comes on, it indicates the
occurrence of a fault in one of
the braking systems:
- signifi cant drop in the level in the cir- cuit,
- electronic brake force distribution (EBFD) faulty (simultaneous lighting
of the ABS warning light),
stop the vehicle as soon as it is safe to
do so.
When the vehicle is moving, check that
the handbrake is fully released.
Any fault resulting in the displaying
of a warning light must be the sub-
ject of further diagnostics by read-
ing the associated message on the
multifunction display.
Should you encounter any prob-
lems, do not hesitate to contact a
CITROËN dealer.
Warning lights

CHECKS
CHECKING LEVELS Brake fluid level
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or us-
ing the dipstick.
Between two oil changes, the consump-
tion should not exceed 0.5 litre per
600 miles (1,000 km). The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Draining the circuit
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Coolant level The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the ig-
nition off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with water.
Draining the engine
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer’s re-
commendations. Fluid specifi cation
The brake fl uid must conform to the
manufacturer’s recommendations and
fulfi l the DOT4 standards.
Fluid specifi cation
The coolant must conform to the manu-
facturer’s recommendations.
Draining the circuit
The coolant does not have to be
changed.
Screenwash fluid level
Top up the level when neces-
sary.
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding circuit checked by a
CITROËN dealer.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

PRACTICAL INFORMATION
TOWING A TRAILER, A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
The maximum towing load on a long
slope depends on the gradient and the
ambient temperature.
In all cases, pay attention to the coolant
temperature.
Side wind

 Take into account the increased
sensitivity to side wind.
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.

 To lower the engine speed, reduce
your speed. Braking
Towing a trailer increases the braking
distance.
Tyres

 Check the tyre pressures of the tow-
ing vehicle and of the trailer, observ-
ing the recommended pressures.
Lighting

 Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
 If the warning lamp and
the STOP warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.
Towbar suited to the attachment of a
trailer or caravan with additional signal-
ling and lighting.
Distribution of loads

 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 towing load
must be reduced by 10 % and so on for
every 1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towing loads
which apply to your vehicle.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and its
driver must be particularly careful.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer.
If the trailer is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted using the electrical
pre-equipment installed at the rear
of the vehicle, in accordance with
the manufacturer's instructions.
