Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise their
fuel consumption and CO
2emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency indicator prompts you to
engage the most suitable gear: whenever this
indication is displayed on the instrument panel,
follow it straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These attitudes
help to save fuel, reduce CO
2 emissions and
decrease general traffic noise.
If the vehicle has the steering-mounted
"CRUISE" control, use cruise control at speeds
above 25 mph (40

km/h) when the traffic is
flowing well.
Use electrical equipment wisely
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (sunroof blind and window blinds, etc.).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Switch off the headlamps and foglamps when
the visibility conditions do not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a passenger, avoid connecting your
multimedia devices (film, music, video game,
etc.) to help reduce consumption of electrical
energy, and hence fuel.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the
heaviest items in the boot, as close as possible
to the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (roof bars, roof rack, bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Avoid using the SPORT mode for too long, in
order to limit your fuel consumption.
Comply with servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journey
.
–

at each change of season.
–


after a long period out of use.
Do not overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter

, air filter, passenger compartment filter,
etc.) and observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
is faulty, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle’s
nitrogen oxide emissions to regulatory
compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).

Driving
6Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►

Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
►


Drive smoothly
, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
►

Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended 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).
Never leave children inside the vehicle
unsupervised.
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 on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
►

deactivate the Stop & Start function,
►


drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10

km/h),
►

do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions 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.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having 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.

68
Driving
automatically to preserve the remaining battery
charge.
Starting the engine
With the parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then fully depress the clutch pedal.
► With an automatic gearbox, place the gear
selector in mode N or P then fully depress the
brake pedal.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
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 increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
►

Reduce speed and lower the engine speed,
so as to limit the heating-up. In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
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 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.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– 1. Stop: inserting and removing the key ,
steering column locked.
–

2. Ignition : steering column unlocked, ignition
on, Diesel preheating, engine running.
–


3. Starting
.
Avoid attaching heavy objects to the key or the remote control. It would weigh
down on its shaft in the ignition switch and
could cause a malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops to
the reserve level, the system switches to energy
economy mode : the power supply is cut off

86
Driving
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This threshold determines how you wish to be
warned of the presence of a moving or stationary
vehicle in front of you, or a pedestrian present in
your traffic lane.
The current threshold can be modified via the
vehicle configuration menu.
You can select one of three pre-defined
thresholds:
– "Distant",
– "Normal",
– "Close".
The last threshold selected is memorised when
the ignition is switched off.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if you press
the brake pedal.
– warns the driver that their vehicle is at risk of
collision with the vehicle in front or a pedestrian.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
This system is comprised of three functions:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Operating conditions and
limits
The ESC system must not be faulty.
The ASR system must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
–

towing a trailer
,
–

carrying long objects on roof bars or roof rack,
–


with snow chains fitted,
–


before using an automatic car wash, with the
engine running,
–


before placing the vehicle on a rolling road in
a workshop,
–


towed vehicle, engine running,
–


Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated after the use of the "space-saver" type
spare wheel is detected, or if a fault with the
lateral brake lamps is detected.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of your
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed on
the touch screen.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.

Driving
or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids.


Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
The state of the system stays in the memory
when switching off the ignition.
The system is automatically deactivated
when towing with a towing device
approved by CITROËN.
Conditions for operation
– All vehicles are moving in the same direction
and in adjacent lanes.
–

The speed of your vehicle must be between 7
and 87 mph (12 and 140

km/h).
–

When overtaking a vehicle, the speed
difference is less than 6

mph (10 km/h).
–

When overtaken by a vehicle, the speed
difference is less than 16

mph (25 km/h).
–

T
raffic is flowing normally.
–

Overtaking a vehicle over a certain period of
time and the vehicle being overtaken remains in
the blind spot.
–


Y
ou are driving on a straight or slightly curved
road.
–

Y
our vehicle is not pulling a trailer, a caravan,
etc.
Operating limits



No alert is triggered in the following conditions:
– In the presence of non-moving objects (parked
vehicles, barriers, street lamps, road signs, etc.).
–

Oncoming traffic.
–


Driving on a winding road or a sharp corner
.
–

When overtaking or being overtaken by a very
long vehicle (lorry

, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
–

When overtaking quickly
.
–

In very heavy traffic: vehicles detected in
front and behind are confused with a lorry or a
stationary object.
Malfunction
In the event of a malfunction, you are warned by
the display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on the
front and rear bumpers with adhesive labels

92
Driving
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or when the speed of the vehicle exceeds 6 mph
(10
km/h).
The sound emitted by the speaker (front or rear) locates the obstacle in relation to
the vehicle, in the vehicle trajectory, in front or
behind.
Deactivation / Activation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
The rear parking sensors system will be deactivated automatically if a trailer or
bicycle carrier is connected to a towing device
installed in accordance with the
manufacturer's recommendations.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when
changing into reverse, this warning lamp
comes on on the instrument panel, accompanied
by an onscreen message and an audible signal
(short beep).
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Reversing Camera
Refer to the General recommendations on the
use of driving and manoeuvring aids .


The reversing camera is automatically activated
when reverse gear is engaged.
The image is displayed on the touch screen.
The reversing camera function may be
supplemented with parking sensors.


The representation with overlaid lines helps with
the manoeuvre.
They are represented as lines marked "on the ground" and do not indicate the
position of the vehicle in relation to tall
obstacles (e.g. other vehicles).
Some distortion of the image is normal.
It is normal to have a part of the number plate
showing at the bottom of the screen.
The blue lines 1 represent the general direction
of the vehicle (the gap represents the width of
your vehicle without the mirrors).
The red line 2 represents a distance of about
30

cm beyond the edge of your vehicle's rear
bumper.
The green lines 3 represent distances of about 1
and 2 metres beyond the edge of your vehicle's
rear bumper.
The turquoise blue curves 4 represent the
maximum turning circle.
Opening the tailgate causes the display
to disappear.

Towing device
Distribution of loads
► 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 performance.
The maximum load which
can be towed must be reduced by 10% per
1,000
metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country in which you are driving.
Remove the quickly detachable towball
when not towing a trailer.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as air conditioning, heated rear
screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
System which manages the duration of use of
certain functions to conserve a sufficient level of
charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics

Technical data
9Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.
The maximum power corresponds to the value type-approved on a test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a CITROËN dealer
or a qualified workshop.
Weights and towed loads
The weights and towed loads relating to
the vehicle are indicated on the registration
document, as well as in sales brochures.
These values are also indicated on the
manufacturer's plate or label.
For more information, contact a CITROËN dealer
or a qualified workshop.
The GTW (Gross Train Weight) values and the
towable loads listed are valid for a maximum
altitude of 1,000
metres. The towable load must
be reduced by steps of 10% for each additional
1,000 metres.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
When exterior temperatures are high, the
vehicle performance may be limited in
order to protect the engine. When the exterior
temperature is higher than 37°C, reduce the
towed weight.
Towing even with a lightly loaded vehicle can adversely affect its road holding.
Braking distances are increased when towing
a trailer.
When using a vehicle to tow, never exceed
a speed of 62 mph (100
km/h) (observe the
local legislation in force).
