2018 CITROEN DS4 fuel consumption

146
Malfunction
When the ignition is on, a message appears
in the instrument panel screen to indicate a
gearbox fault.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel a
substantial jolt when changing from P to R and
from N to R. This will not cause any damage to
the gearbox.
Do not exceed around 60 mph (100 km/h), local
speed restrictions permitting.
Have it checked by a network dealer or a
qualified workshop.There is a risk of damage to the gearbox:
-

i
f you press the accelerator and brake
pedals at the same time,
-

i
f you force the selector from position P
to another position when the battery is
flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear selector at N and apply the
parking brake, unless it is programmed
in automatic mode.
Gear efficiency indicator
(Depending on engine.) System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. The system adapts its gear change
recommendation according to the
driving conditions (slope, load,...) and
the demands of the driver (power,
acceleration, braking,...).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
The information appears in the instrument
panel in the form of an arrow. With a manual gearbox, the arrow may be
accompanied by the gear recommended.

Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in the traffic (red lights, traffic jams,...).
The engine restarts automatically – START
mode – as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Operation
Going into engine STOP mode
The " ECO" warning lamp comes on in
the instrument panel and the engine
goes into standby automatically:
- with a manual gearbox , at speeds below
12 mph (20 km/h) or when the vehicle is
stationary with the PureTech 130 petrol and
BlueHDi 115 and 120 Diesel versions, when
you place the gear lever in neutral and you
release the clutch pedal,
-

W
ith an automatic gearbox , when the
vehicle is stationary and when you press
the brake pedal or put the gear selector in
position N . If your vehicle is fitted with this
system, a time counter calculates
the time spent in STOP mode
during a journey. It resets to
zero every time the ignition is
switched on with the key or the
"START/STOP" button.
STOP mode does not affect the operation
of vehicle systems such as braking, power
steering...
Never refuel with the engine in STOP
mode; you must switch off the ignition with
the key or the "START/STOP" button.
Special cases: STOP mode not
available
STOP mode is not activated when:
- t he vehicle is on a steep slope (uphill or
downhill),
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he vehicle has not exceeded 6 mph (10
km/h) since the last engine start (with the
key or the "START/STOP" button),
-

t
he electric parking brake is applied or being
applied, -

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-
d
emisting is active,
-
c
ertain special conditions (battery charge,
engine temperature, braking assistance,
exterior temperature, etc.) require the
engine to be running to assure control of a
system.
In this case, the " ECO" warning
lamp flashes for a few seconds then
goes off.
This operation is perfectly normal.
Going into engine START mode
The ECO warning lamp goes off and
the engine starts automatically:
-

w

ith a manual gearbox , when you fully
depress the clutch pedal,
-

w

ith an automatic gearbox:
•

g

ear selector in position D or M , when
you release the brake pedal,
•

o

r gear selector in position N and brake
pedal released, when you place the gear
selector in position D or M ,
•
o

r when you engage reverse gear.

Tyre under-inflation
d
etection
The tyre under-inflation detection system
is an aid to driving which does not replace
the need for vigilance on the part of the
driver. This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
Tyre pressure should be checked when
the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than
6 miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. This warning is indicated by
continuous illumination of the lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.
F

R
educe speed immediately, avoid excessive
steering movements and sudden braking.
F

S
top as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.

Manual parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked in the dealer
network or by a qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked in the dealer network or by
a qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Only use products recommended by DS
AUTOMOBILES or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in
the braking system, DS AUTOMOBILES
selects and offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
AdBlue® (BlueHDi
engines)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or
fuel consumption of Diesel engines, DS
AUTOMOBILES has taken the decision to
equip its vehicles with a system that associates
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 oxides of nitrogen (NOx) into nitrogen and
water, which are harmless to health and the
environment.
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.
Brake disc/drum wear
For information on checking brake
disc wear, contact the dealer
network or a qualified workshop.

Identification markings
Various visible markings for the identification of
your vehicle.
A. Vehicle identification number (V.I.N.),
under the bonnet.
The number is engraved on the body structure.
B. Vehicle identification number (V.I.N.), on
the dashboard.
The number is on a label, visible through the
windscreen. C. Manufacturer's label.
This tamperproof label is affixed to the driver's
door aperture.
It bears the following information:
-

t
he name of the manufacturer,
-

t
he European Whole Vehicle Type Approval
number,
-

t
he vehicle identification number (V.I.N.),
-

t
he gross vehicle weight (GV W)
-

t
he maximum authorised vehicle + trailer
weight (the Gross Train Weight or GTW),
-

t
he maximum weight on the front axle,
-

t
he maximum weight on the rear axle.
D. Tyres/paint code label.
This label is affixed to the driver's door
aperture.
It bears the following information on the tyres:
-

t
he tyre pressures, unladen and laden,
-

t
he tyre specification, made up of the
dimensions and type as well as the load and
speed indices,
-

t
he spare tyre pressure.
It also indicates the paint colour code. The vehicle may be originally equipped
with tyres with higher load and speed
indices than those indicated on the label,
without affecting inflation pressure.
Checking tyre pressures
The tyre pressures should be checked when
cold at least monthly.
The pressures given on the label are valid for
cold tyres. If you have driven for more than 10
minutes or more than 6 miles (10 kilometres)
at more than around 30 mph (50 km/h), the
tyres will be warm; in this case 0.3 bar (30 kPa)
should be added to the pressures given on the
label. Never reduce the pressure of a warm tyre.
Low tyre pressures increase fuel
consumption.
