Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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
► 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
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► 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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant 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.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a CITROËN dealer.
For safety and theft protection reasons,
never leave the electronic key in the
vehicle, even when you are close to it.

Driving
6With an automatic gearbox, the system is
only active in manual operation.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g.
slope, load) and driving style
(e.g.
power demand, acceleration, braking).
The system never suggests:
–

engaging first gear;
–


engaging reverse gear
.
Hill start assist
This system keeps the vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
The system is only active when:
–

The vehicle is completely stationary
, with your
foot on the brake pedal.
–

Certain slope conditions are met.
–


The driver
’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. Then check that the parking
brake indicator lamp is on fixed on the
instrument panel.
The hill start assist function cannot be deactivated. However, using the parking
brake to immobilise the vehicle interrupts its
operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when you
release the brake pedal:
–

provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.

96
Driving
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►

If it is not possible to carry out this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
The reinitialisation of the system is done with the
ignition on and the vehicle stationary:
–

V

ia the vehicle configuration menu for vehicles
fitted with a touch screen.
–

V

ia the button on the dashboard for vehicles
without a touch screen.
With/Without audio system



► Press and hold this button.
Reinitialisation is confirmed by a high-pitched
audible signal.
A
low-pitched audible signal indicates that
the reinitialisation operation has not been
successful.
With touch screen
► In the menu Driving / Vehicle, select
the tab "Driving functions ", then "Reset
under-inflation detection ".
►

Select "
Ye s" to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a CITROËN dealer or a
qualified workshop.
"Space-saver" type spare wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel
has been replaced by one of uniform size (the
same as the others), the pressure readjusted
and the reinitialisation carried out.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.

Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
terrain.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors, as well as
any associated functions, may be disrupted
by noise pollution such as that emitted by
noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
