2023 CITROEN DS3 CROSSBACK fuel pressure

7Eco-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.
Favour the use of the "Eco" driving mode by
selecting it using the "Drive Mode" control.
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.
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.
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 journe
y.
–

a
t each change of season.
–

a
fter 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
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).

2. Front right seat belt warning lamp
3. Rear left seat belt warning lamp
4. Rear centre seat belt warning lamp
5. Rear right seat belt warning lamp
If the corresponding seat belt is not fastened
or is unfastened, when the ignition is switched
on, the seat belts warning lamp comes on in the
instrument panel and the corresponding warning
lamp (1 to 5) comes on in red in the seat belt and
front passenger airbag warning lamps display.
If a rear seat belt is not fastened, the
corresponding warning lamp (3 to 5)
comes on for around 30 seconds.
From about 12 mph (20 km/h) and for 2 minutes,
each warning lamp corresponding to an occupied
seat whose seat belt is unfastened flashes,
accompanied by an audible signal. After these 2
minutes, the corresponding seat warning lamp
Sand
This mode allows little spin on the two driving
wheels at the same time to allow the vehicle to
move forward and limit the risks of getting stuck
in the sand.
(mode active up to 75 mph (120 km/h))
Do not use the other modes on sand as
the vehicle may become stuck.
Recommendations
The vehicle is designed principally to
drive on tarmac roads, but it allows you to
occasionally drive on other less passable
terrain.
However, it does not permit off-road driving
such as:
–

driving on t
errain which could damage the
underbody or strip away components (fuel
pipe, fuel cooler, etc.) due to obstacles or
stones in particular,
–

driving on t
errain with steep gradients and
poor grip,
–

cro
ssing a waterway.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat belt
on the chest of the occupant, thus improving their
protection.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device may
trigger before and independently of airbag
deployment. Deployment of the pretensioners
is accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt system
checked, and if necessary replaced, by a dealer
or a qualified workshop.
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting system.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
Fastening
►  Pull the strap, then insert the tongue in the
buckle.
►  Check that the seat belt is fastened correctly
by pulling the strap.
Unlocking
►  Press the red button on the buckle.
►  Guide the seat belt as it is reeled in.

Driving06
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
►  With a manual gearbox: with the clutch pedal
fully depressed.
►  With an automatic gearbox:
•

With the select
or in position D or M: with the
brake pedal released.
•

With the select
or in position N and the brake
pedal released: with the selector at D or M.
•

With the select
or in position P and the brake
pedal depressed: with the selector at R, N, D
or M.
•

R
everse gear engaged.
Special cases
The engine restarts automatically if all the
operating conditions are met again and in the
following cases.
–
With a manual gearbo
x: vehicle speed exceeds
2.5 mph (4 km/h),
–

With an aut
omatic gearbox, in mode N, vehicle
speed exceeds 0.6 mph (1 km/h).
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, this warning
lamp flashes for a few moments, then
remains on, accompanied by an onscreen
message.
Have the vehicle checked by a dealer or a qualified
workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►  Switch off the ignition then start the engine
again with the "START/STOP" button.
The Stop & Start system requires a 12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a dealer or a qualified
workshop.
Under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which must
be reinitialised every time the tyre pressures are
adjusted or a wheel changed.
The system triggers an alert as soon as it detects
a drop in the inflation pressure of one or more
tyres.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high speed,
long journey):
–

w
orsens road-holding.
–

lengthens braking dist
ances.
–

c
auses premature wear of the tyres.
–

increase
s fuel consumption.
The inflation pressures defined for the
vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures shown
on the label.
Under-inflation alert
This is signalled by the fixed illumination of
this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►  Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
►  Stop the vehicle as soon as it is safe to do so.

140
Practical information07
► Clip the stay in its housing.
►  Lower the bonnet and release it near the end
of its travel.
►  Pull on the bonnet to check that it is locked
correctly.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water (rain,
washing, etc.) be limited.

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a dealer or a
qualified workshop.
The fluids must comply with the
manufacturer's requirements and with
the vehicle's engine.
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a dealer or a qualified
workshop.
Engine oil
The level is checked, with the engine
having been switched off for at least 30
minutes and on level ground, using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended that
you check the level, and top up if necessary, every
3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►  Grasp the dipstick by its coloured grip and pull
it out completely.

Practical information07
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electric parking brake
This system does not require any routine
servicing. However, in case of an issue, do
not hesitate to have the system checked by a
dealer or a qualified workshop.
For more information on the Electric
parking brake, refer to the corresponding
section.
Brake pads
Brake wear depends on the style of driving,
particularly in the case of vehicles used in
town, over short distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads are
worn.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a dealer or a qualified
workshop.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure label
are valid for "cold" tyres. If you have driven for
more than 10 minutes or more than 6 miles (10
kilometres) at over 31 mph (50 km/h), add 0.3 bar
(30 kPa) to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
