low oil pressure CITROEN DS3 CROSSBACK 2023 Owners Manual

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).

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.

142
Practical information07
The check and top-up must only be done with the
engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the "MAX"
mark but should never exceed it.
If the level is close to or below the "MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi), and
in particular on the supply of AdBlue, refer to the
corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according to
your engine.
Otherwise, have them checked by a dealer or a
qualified workshop.
Only use products recommended by the
Manufacturer or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, the Manufacturer selects and
offers very specific products.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by a
dealer or by a qualified workshop.
Passenger compartment filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city
driving), change it twice as often, if necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate undesirable
odours.
Air filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city
driving), change it twice as often, if necessary.
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).

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

147
Practical information07
Promptly clean up any stains containing
chemicals liable to damage the vehicle's paint
(including tree resin, bird droppings, insect
secretions, pollen and tar).
If justified by the environment, clean the
vehicle more frequently to remove salty
deposits (in coastal areas), soot (in industrial
estates) and mud (in wet or cold areas). These
substances can be highly corrosive.
Contact a dealer or a qualified workshop if you
require advice on removing stubborn stains
requiring special products (such as tar or
insect removers).
Preferably, have paint touch-ups performed by
a dealer or a qualified workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure washer to
clean the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage if they come into contact with the
controls in the dashboard and centre console.
Take care!
Bodywork
High-gloss paint
Do not use abrasive products or solvents,
petrol or oil to clean the bodywork.
Never use an abrasive sponge to clean
stubborn stains. Risk of scratching the
paintwork!
Do not apply polish in strong sunshine, or to
plastic or rubber parts.
Use a soft sponge and soapy water or a pH
neutral product.
Gently wipe the bodywork with a clean
microfibre cloth.
Apply polish with the vehicle clean and dry.
Comply with the instructions for use stated on
the product.
Decals
(Depending on version)
Do not use a high pressure washer to
clean the vehicle. Risk of damaging or
detaching the decals!
Use a high-flow hose at a temperature
between 25°C and 40°C.
Sweep the jet of water across the surface to be
cleaned, perpendicular to it.
Rinse the vehicle with demineralised water.
Leather
Leather is a natural product. Appropriate regular
care is essential for its durability.
It must be protected and nourished using a
specific leather product, to keep it supple and
preserve its original appearance.
Do not clean leather using unsuitable
cleaning agents such as solvents,
detergents, petrol or pure alcohol.
When cleaning items partly made from leather,
take care not to damage the other materials
with the specific leather product.
Before cleaning greasy stains or liquids,
quickly mop up any surplus.
Before cleaning, wipe off any residues liable
to scuff the leather, using a cloth that has
been dampened with demineralised water and
thoroughly wrung out.
Clean leather using a soft cloth moistened
with soapy water or a pH-neutral product.
Dry with a soft, dry cloth.

151In the event of a breakdown08

► Connect the hose from the bottle of sealant
to the valve of the tyre to be repaired and tighten
firmly.
►  Check that the compressor switch is in
position "O".
►  Fully uncoil the electric cable stowed under
the compressor.
►  Connect the compressor's electric plug to the
vehicle's 12 V socket.
►  Affix the speed limit sticker.
The speed limit sticker must be secured to
the interior of the vehicle in the area close
to the driver, to remind the driver that a wheel
is in temporary use.
The tyre inflation pressures are given on
this label.


►  Switch on the ignition.

► Switch on the compressor by moving the
switch to position "I" until the tyre pressure
reaches 2 bar. The sealant product is injected
under pressure into the tyre; do not disconnect
the pipe from the valve during this operation (risk
of blowback).
If after approximately 7 minutes, the
pressure of 2 bar is not reached, this
indicates that the tyre is not repairable;
contact a dealer or a qualified workshop for
assistance.
►  Move the switch to position "O".
►  Disconnect the compressor's electric plug
from the vehicle's 12 V socket.
►  Refit the cap on the valve.
►  Remove the kit.
►  Remove and store the bottle of sealant.
The sealant product is harmful if
swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle in standard
waste, take it to a dealer or an authorised
waste disposal site.
Do not forget to obtain a new bottle of
sealant, available from a dealer or a qualified
workshop.


►  Drive immediately for approximately 3 miles
(5 kilometres) at reduced speed (between 12 and
37 mph (20 and 60 km/h)) to plug the puncture.
►  Stop to check the repair and the tyre pressure
using the kit.
With a tyre repaired using this type of kit,
do not exceed a speed of 50 mph
(80 km/h) and do not drive more than
125 miles (200 km).
Contact a dealer or a qualified workshop to
have the tyre changed.
