Driving recommendations
Observe the driving regulations and remain vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at
any time to any eventuality.
As a safety precaution, the driver must only carry out actions requiring sustained attention when
the vehicle is stationary.
On a long journey, a break every two hours is strongly recommended.
In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from
other vehicles.Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes
after switching off the engine, do not
park or leave the engine running over
areas where inflammable substances
and materials are present: grass,
leaves,
etc.
Never leave a vehicle unsupervised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the gearbox into neutral or
position


N or P, depending on the type
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
- check that the depth of water does not exceed 15 cm, taking account of waves
that might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10
km/h),
-

d
o not stop and do not switch off the
engine.
If you are obliged to drive through water:
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest 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 per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side 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 a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
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 Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar 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.

If one of the starting conditions is not
met, a reminder message appears in
the instrument panel screen. In some
circumstances, it is necessary to
turn the steering wheel slightly while
pressing the " START/STOP " button
to assist unlocking of the steering;
a message warns you when this is
needed.
The presence of the "Keyless Entry
and Starting" electronic key in the
recognition zone is essential.
As a safety measure, do not leave this
zone with the vehicle running.
Diesel vehicles
In temperatures below zero
the engine will not start until
the preheater warning lamp

Stop & Start
Operation
Going into engine STOP mode
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in
STOP mode; you must switch off the
ignition with the key or the "START/
STOP" button.
With a manual gearbox, at a
speed below 12 mph (20 km/h),
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP STOP mode is not invoked when:
-
t
he vehicle is on a steep slope (up or
d ow n),
-
t
he driver's door is open,
-
t
he driver's seat belt is not fastened,
-
t
he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start (using
the key or the "START/STOP" button),
-
t
he electric parking brake is applied or
being applied,
-
t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-
d
emisting is active,
-
s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
Special cases: STOP mode
unavailable
In this case, the "ECO" warning lamp
flashes for a few seconds, then goes
of f.
This operation is perfectly normal.
With an automatic gearbox,
when
the vehicle is stationary, this warning mode during a journey. It resets itself to zero
every time the ignition is switched on with the
key or the "START/STOP" button.
The Stop & Start

system puts the engine temporarily into standby - STOP mode - during stops in
the traffic (red lights, traffic jams, or other...). The engine restarts automatically - START mode - as
soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as
well as the noise level when stationary.
or when the vehicle is stationary with the
PureTech

Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.
For more information on the Electric parking
brake , refer to the corresponding section.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.

Engines
Engine characteristics
The engine characteristics (capacity, maximum
power, maximum engine speed, fuel, CO
2
emissions, etc.) for your vehicle are given in
the registration document, as well as in sales
brochures.
These characteristics correspond to the
values type-approved on a test bed, under
conditions defined in European legislation
(Directive
1

999/99/EC).
For more information, contact a CITROËN
dealer or a qualified workshop.
Weights
Weights and towed loads
The maximum weights and towed loads for your
vehicle are given are given in the registration
document, as well as in sales brochures.
These values are also present on the
manufacturer's plate or label.
For more information, contact a CITROËN
dealer or a qualified workshop.
The kerb weight is equal to the unladen
weight
+ driver (75 kg).
The GTW and towed load values indicated
apply up to a maximum altitude of
1
000 metres; the towed load mentioned
must be reduced by 10 % for every additional
1
000 metres.
The weight of the braked trailer can be
increased, within the GTW limit, on condition
that the GV W of the towing vehicle is reduced
by the same amount.
The recommended nose weight is the vertical
load on the towbar ball (removable with or
without tools).
GV W:

g
ross vehicle weight, the maximum
authorised vehicle weight.
GT W:

g
ross train weight, the maximum
authorised weight of vehicle plus trailer. High exterior temperatures may result
in a reduction in the per formance of
the vehicle to protect the engine; when
the exterior temperature is higher than
37
°C, limit the towed weight.
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. Towing with a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
Never exceed 60 mph (100 km/h) when
towing (comply with the legislation in
force in your country).
