Park Assist
This system provides active assistance with parking, detecting a parking space then controlling the steering to park in the space. It controls the steering while the driver manages the accelerator, brakes, gears andclutch (manual gearbox). During phases of entry into and exit from a parking space, the system provides visual and audible information
to the driver in order to make the manoeuvres safe. It may be necessary to move for wards and backwards more than once.
During a manoeuvre the steering wheelturns quickly: do not hold the steeringwheel, do not place your hand between
the spokes of the steering wheel and take care with loose and bulky clothing, scarves, handbags... There is a risk of injury.


When Park Assist is activated, itprevents a change to STOP mode of Stop & Start. In STOP mode, activation of Park Assist restarts the engine.


The Park Assist system cannot in anycircumstances replace the care and responsibility of the driver.
The driver must remain in control of their vehicle ensuring that thespace remains clear throughout themanoeuvre. In some circumstances, the sensors may not detect small obstacles located in their blind spots.
The driver can take control at any time bygripping the steering wheel.
The Park Assist s
ystem provides assistance for
the following manoeuvres:


- entr
y into a parallel parking space

- exitin
g from a parallel parking space

- ba
y parking

The Park Assist system takes control of the power steering for a maximumof 4 manoeuvre cycles. The functionis deactivated after these 4 cycles.If you think that your vehicle is notpositioned correctly, you should then take control of the steering to carry outthe manoeuvre.

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.
