2017 CITROEN DS7 CROSSBACK fuel consumption

8Eco-driving
Eco-driving
Eco-driving refers to a range of everyday practices
that allow the motorist to optimise the vehicle's
energy consumption (fuel and/or electricity) and
CO
2 emissions.
Optimise your use of the gearbox
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift 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 practices
help to save on energy consumption, reduce CO
2
emissions and decrease general traffic noise.
Favour the use of the "Eco" driving mode by
selecting it using the "DRIVE MODE" control.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of 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. 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
(e.g. sunroof blind, window blinds).
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.
Adapt your use of the headlamps and/or foglamps
to the level of visibility, in accordance with
current legislation in the country in which you are
driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The vehicle
will warm up much faster while driving.
As a passenger, avoid connecting your multimedia
devices (e.g. film, music, video game) to help
reduce the consumption of energy.
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 (e.g. roof bars, roof rack, bicycle
carrier, trailer). 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.
Comply with the 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 journe
y.
–

a
t each change of season.
–

a
fter a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g. engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, your vehicle will emit pollution. Visit a
dealer or a qualified workshop as soon as possible
to restore your vehicle's nitrogen oxide emissions
to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, 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).
Optimising the driving range (rechargeable
hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.

Driving06
The system uses a computer and sensors, which
determine the optimal level of shock absorption
to be applied to each shock absorber.
The system is also associated with a camera,
located at the top of the windscreen, constantly
monitoring the road condition. Based on the
information transmitted by the camera, the
system anticipates possible road defects.
The operation of the system depends on the
driving mode selected (depending on equipment).
For more information on the Driving modes,
please refer to the corresponding section.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel.

Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135 km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument panel.
The vehicle automatically changes to Hybrid
mode.
If an LED comes on under the interior rear view
mirror, visible from outside the vehicle, this

utside temperature between approximately
-5°C and 45°C.
Manually exiting the mode
►  Fully depress the accelerator pedal, or
►  Select another mode.
In case of non-use of the vehicle for a long
period (several months), a restart of the
petrol engine may occur even if the battery is
charged.
Depending on equipment, Electric mode is
combined with Normal mode of the DS
ACTIVE SCAN SUSPENSION function.
For more information on DS ACTIVE SCAN
SUSPENSION, refer to the corresponding
section.
In the event of multiple starts of the
internal combustion engine without a
sufficient rise in
temperature,  Electric mode may be temporarily
unavailable (natural phenomenon of dilution of
fuel in oil). The message "Electric mode
unavailable: automatic operation in progress"
then appears on the instrument panel.
To regain normal electrical operation, drive
approximately 50 miles (80 km) in "motorway"
conditions or approximately 125 miles (200
km) in urban conditions.
This phenomenon does not cause any
mechanical or electrical damage. It can occur
several times in the life of the vehicle.
Hybrid
To optimise the vehicle's fuel consumption
by managing the alternating or simultaneous
operation of the two types of engine, depending
on driving conditions and driving style.
In Hybrid mode, it is possible to drive in 100%
electric mode if the battery charge level is
sufficient and acceleration requirements are
moderate.
Depending on equipment, Hybrid mode is
combined with Normal mode of the DS
ACTIVE SCAN SUSPENSION function.
For more information on DS ACTIVE SCAN
SUSPENSION, refer to the corresponding
section.
Sport
To obtain more dynamic driving in order to benefit
from the maximum performance of the vehicle.

Gear shift indicator
(Depending on engine)
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may recommend
skipping one or more gears.
Gear engagement recommendations are not to be
considered mandatory. Indeed, the configuration
of the road, the traffic density and safety remain
determining factors when choosing the best
gear. Therefore, the driver remains responsible
for deciding whether or not to follow the system’s
advice.
The system cannot be deactivated.
The system is only active in mode M of the
automatic gearbox.
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 re
verse gear.
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.

Practical information07
the shock absorbers have a major impact on road
holding and braking performance.
For your safety and driving comfort, it is important
to have them regularly checked by a dealer or a
qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or
fuel consumption of its Diesel engines, the
Manufacturer has taken the decision to equip
its vehicles with a system that combines SCR
(Selective Catalytic Reduction) with a Diesel
Particle Filter (DPF) for the treatment of exhaust
gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special tank
holding about 17 litres.
Its capacity allows a driving range of
approximately 3,900 miles (6,500 km), which may
vary considerably depending on your driving style.
An alert system is triggered once the reserve level
is reached: it is then possible to drive for a further
1,500 miles (2,400 km) before the tank is empty
and the vehicle is immobilised.
For more information on the Warning and
indicator lamps and the associated alerts,
or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a dealer or a
qualified workshop. After 660 miles (1,100 km),
a device is automatically activated to prevent
the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped up
as soon as the first alert is issued indicating that
the reserve level has been reached.
For the correct operation of the SCR
system:
–

U

se only AdBlue
® fluid that meets the ISO
22241 standard.
–

Ne

ver transfer AdBlue
® to another container
as it would lose its purity.
–

Ne

ver dilute AdBlue
® with water.
You can obtain AdBlue
® from a dealer or a
qualified workshop, as well as service stations
equipped with AdBlue
® pumps specially designed
for passenger vehicles.
Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
