In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to 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.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.

f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible. New vehicle
Do not pull a trailer before having driven at
least 620 miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing device is used. If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1 to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised to enable
vehicle start.
This electronic engine immobiliser locks
the engine management system a moment
after the ignition is switched off and prevents
unauthorised engine starting.
In the event of a fault, you are
informed by the illumination of this
warning lamp, an audible signal and
a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer or a qualified workshop as
soon as possible.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with
you.

then R .
Stopping the vehicle
Before switching off the engine, you can:
-
p ress control N to be in neutral,
or
-

l
eave the vehicle in gear; in this case the
vehicle cannot be moved.
For all parking situations, you must apply
the parking brake to immobilise the
vehicle.
When immobilising the vehicle with the
engine running, you must select neutral N .Before doing anything under the bonnet,
ensure that control N has been pressed
and that the parking brake is applied.
Operating fault
With the ignition on, illumination of
this warning lamp, accompanied by
an audible signal and a message,
indicates a gearbox fault.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears. The system is only active on vehicles fitted
with a manual gearbox.
On certain BlueHDi Diesel versions with
manual gearbox, in certain driving conditions
the system may suggest changing into neutral
so that the engine can go into standby (STOP
mode with Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
Gear efficiency recommendations are for
information only. In fact, the road layout, the
traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued
by the system.
This function cannot be disabled.
The information appears in the instrument
panel in the form of an arrow.
Driving

107
The system adapts its gear change
recommendation according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e
ngaging first gear,
-
enga

ging reverse gear.
-
enga

ging a lower gear.
On vehicle fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle stationary
for a short time (approximately two seconds)
when starting on a gradient, the time it takes
to move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain conditions of gradient are met,
-

t
he driver's door is closed.
The hill start assist system cannot be
deactivated. Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp is showing fixed on
the instrument panel.

If the camera has confirmed
the presence of a vehicle or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
Important: if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The point at which braking is triggered
may be adjusted depending on the driving
actions of the driver, such as movement
of the steering wheel or actions on the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for 1
to 2 seconds. With a manual gearbox, in the event of
automatic emergency braking until the
vehicle comes to a complete stop, the
engine may stall.
With an automatic or electronic gearbox,
in the event of automatic emergency
braking until the vehicle comes to a
complete stop, keep the brake pedal
pressed down to prevent the vehicle from
starting off again.
Specific conditions for operation
The vehicle's speed must be between 3 mph
and 53 mph (5 km/h and 85 km/h) when a
moving vehicle is detected.

Fuel cut- of f
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention
(Diesel)
(Depending on the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
It remains possible to use a fuel can to fill
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, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network whether
your vehicle is suitable for the fuel pumps
in the country in which you intend to travel.
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
