Eco- driving
Optimise the use of your
gearbox
With a manual gearbox, move off gently
and change up without waiting. During
acceleration, change up early.
With an automatic or electronic gearbox,
give preference to automatic mode and avoid
pressing the accelerator pedal heavily or
suddenly.
Adopt a smooth driving style
Maintain a safe distance between vehicles,
use engine braking rather than the
brake pedal, and press the accelerator
progressively. These practices contribute
towards a reduction in fuel consumption and
CO
2 emissions and also help to reduce the
background traffic noise.
If your vehicle has cruise control, make use of
the system at speeds above 25 mph (40 km/h)
when the traffic is flowing well.
Control the use of your electrical
equipment
Before moving off, if the passenger
compartment is too warm, ventilate it by
opening the windows and air vents before
using the air conditioning.
Above 31 mph (50 km/h), close the windows
and leave the air vents open.
Remember to make use of equipment that can
help keep the temperature in the passenger
compartment down (sunroof and window
blinds, etc.).
Switch off the air conditioning, unless it has
automatic regulation, as soon as the desired
temperature is attained. Switch off the lamps and foglamps when the
ambient light level does not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving. Switch off the demisting and defrosting
controls when not required, if they are not
automatically controlled.
Switch off the heated seat as soon as
possible.
As a passenger, if you avoid connecting your
multimedia devices (film, music, video game,
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
leaving the vehicle.
The gear efficiency indicator invites you to
engage the most suitable gear: as soon as the
indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted with an electronic or
automatic gearbox, this indicator appears only
in manual mode. Eco-driving is a range of everyday practices
that allow the motorist to optimise their fuel
consumption and CO
2 emissions.

Electronic stability control
(ESC)
Electronic stability control integrating the
following systems:
-
a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and
contributes towards improved control on corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system (EBFD)
manages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
If you benefit from the Citroën Connect
Box offer with the SOS and assistance
pack included, there are additional
ser vices available to you in your personal
space, via the website for your country.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
The fixed illumination of this warning
lamp indicates that there is a fault
with the ABS.
If this warning lamp comes on, in
conjunction with the STOP
and
ABS warning lamps, an audible
signal and a message, this indicates
that the electronic brake force
distribution (EBFD) is faulty.
You must stop as soon as it is
safe to do so.
In both cases, have the system
checked by a CITROËN dealer or
a qualified workshop as soon as
possible.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
If you need to brake in an emergency,
press the brake pedal ver y firmly and
keep the pressure applied.
Safety

94
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 measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, a break every two hours is
strongly recommended.
In bad weather, drive smoothly, anticipate the
need to brake and increase the distance from
other vehicles.Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving.
Important!
Never drive with the parking brake applied –
Risk of overheating and damage to the
braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, fallen leaves, etc.): Risk of fire!
Never leave a vehicle unsuper vised 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. If you are obliged to drive through water:
-

c
heck 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 function,
-
d
rive as slowly as possible without stalling.
Under no circumstances exceed 6 mph
(10

km/h),
-
d
o not stop and do not switch off the engine.
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 about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.

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

I
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.
