Driving advice


Distribution of loads
)Distribute the load in the trailer so that theheaviest 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 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 electricall
y controlled, its cooling capacity is not dependent on the engine speed.
)
To 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.
) If the warning lamp and the
STOPwarning 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.

R
efer to the "Technical data" section for detailsof the weights and towed loads which apply to your vehicle.


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

When not towing a trailer, remove thequickly-detachable tow ball beforedriving.

Checks























Fuel
Capacity of the tank: approximately 57 litres (petrol) or 55 litres (Diesel).


Low fuel level
Refuelling
When the low fuel level is reached,
this warning lamp in the instrumentpanel comes on, accompanied by anaudible warning, a message and the
last bar of the fuel gauge comes on in orange.
) Take care to select the pump that delivers
the correct type of fuel for your vehicle.) Introduce the nozzle so as to push in themetal non-return flap A.)
Make sure that the nozzle is pushed in as
far as possible before star ting to refuel (risk
of blowback). ) Maintain this position throughout the
refuelling operation.) Push the fuel flap to close it.
If you are filling your tank to the top, do
not persist after the 3rd cut- off; this could cause malfunctions.
A label on the inside of the fuel filler flapreminds you of the type of fuel to use,
depending on your engine type.
Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge. When it
first comes on, about 6 litresof fuel
remain in the tank.
Until sufficient fuel has been added, this warninglamp appears every time the ignition is switched
on, accompanied by an audible warning and amessage. This audible warning and message
are repeated with increasing frequency as the fuel level drops towards "0".
Refuel as soon as possible to avoid running out.
Opening the filler flap may result in an inrush of air. This is entirely normal and results from the
sealing of the fuel system.
) Press the rear edge of the flap to open it
(the filler cap is par t of it).
With Stop & Star t, never refuel with the
system in STOP mode; you must switchoff the ignition with the START/STOP button.

Checks

















Misfuel prevention (Diesel) *


Operation

When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remainsclosed and prevents filling.Do not persist but introduce a Diesel type filler nozzle.

*
Depending on country of sale. Mechanical device which prevents fillin
g the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the
wrong fuel.
It remains possible to use a fuel can tofill the tank. In order to ensure a good flow of fuel,do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device and pour slowly.


Travelling abroad

As Diesel fuel pump nozzles may be different in other countries, thepresence of the misfuel prevention device may make refuelling impossible.
Before travelling abroad, werecommend that you check with the CITROËN dealer network, whether your vehicle is suitable for the fuel pumps inthe country in which you want to travel.
