Dials and screens
Control buttons

With the hybrid system active or when the vehicle is being driven, illumination of one of the following warning lamps indicates a fault which requires action on the par t of the driver.
Any fault resulting in the illumination of a warning lamp must be investigated further by reading the associated message in the instrument panel screen.
If you encounter any problems, contact a CITROËN dealer or a qualified workshop.
Warning / indicator lampStateCauseAction / Observations



STOPfixed, associated with another warning lamp, accompanied by an audible signal and a message in the screen.It is associated with a punctured wheel,
the brakin
g system, the power steering,
the engine oil pressure, the enginecoolant temperature, the hybrid system
or a major electrical fault.Stop as soon as it is safe to do so as the en
gine may cut out.
Park, switch off the ignition and call a CITROËN
dealer or a qualified workshop.



Serviceon temporarily. A minor fault has occurred for which
there is no specific warning lamp. Identify the fault by reading the message shown in the screen, such as, for example:
- the closing of the doors, boot or bonnet,
- the engine oil level,
- the screenwash level,
- the remote control battery,
- the tyre pressures,
- saturation of the par ticle emission filter (Diesel). - ...For any other faults, contact a CITROËN dealer or a
qualified workshop.

fixed.This indicates the low level in theDiesel additive reservoir. Have the level topped up by a CITROËN dealer or a
qualified workshop as soon as possible.

Coolant temperature
gauge
With the hybrid system active:
- in zone A
, the temperature is correct,
- in zone B, the temperature is too high; the central STOP
warning lamp comes on,
accompanied by an audible signal and amessage in the instrument panel screen.You must stop as soon as it is safe to do so.Wait a few minutes before switching off the engine.
Contact a CITROËN dealer or a qualified
workshop.
A
fter driving for a few minutes, the temperature
and pressure in the cooling system increase.
To top up the level:
)
wait for the engine to cool, )
unscrew the cap by two turns to allow the
pressure to drop,
) when the pressure has dropped, remove
the cap,) top up the level to the "MAX" mark.

Be aware of the risk of burns whentopping up the cooling system. Do not fill above the maximum level (indicated on the reservoir).

227Practical information

We recommend the use of genuine
CITROËN towbars and their harnesses that have been tested and approvedfrom the design stage of your vehicle,and that the fitting of the towbar is
entrusted to a CITROËN dealer or aqualified workshop.
If the towbar is not fitted by a CITROËN dealer, it is imperative that it isfitted in accordance with the vehiclemanufacturer's instructions.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so that the
heaviest items are as close as possible to
t
he 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 b
y 10 % for every 1 000 metres of altitude.
Side wind
)
Take into account the increased sensitivity
to side wind.

Cooling
To w i ng 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.
)If the warning lamp and the STOP
warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.



The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.



Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
The maximum towed load on a long incline depends on the gradient and the ambient
tem
perature.
In all cases, keep a check on the coolant
temperature.
R
efer to the "Technical Data" section for details
of the weights and towed loads which apply toyour vehicle.

The various caps and covers allow access for
checking the levels of the various fluids, for replacing cer tain components and for primingthe fuel system.

239Checks
Coolant level
The coolant level should be closeto the "MA X" mark but should never exceed it.


Changing the coolant
The coolant does not have to be changed.


Coolant specifi cation

The coolant must conform to the
manufacturer's recommendations.

Power steering fluid
level
The power steering fluid level should
be close to the "MA X" mark. Unscrew
the cap, with the engine cold,
to check the level. Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Brake fluid level


Changing the fl uid

Refer to the ser vicing booklet for the inter val for
this operation.

Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet the
DOT4 standard.
In addition, as the cooling system ispressurised, wait at least one hour after
switching off the engine before carrying out any work. To avoid any risk of scalding, unscrewthe cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and topup the level. When the en
gine is warm, the temperature of
the coolant is regulated by the fan. This can
operate with the ignition off.
On vehicles which are fitted with a particle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine is cold
