2011 Citroen DS4 fuel consumption

87Comfort








Rear screen demist - defrost

The control button is located on the air conditioning system control panel.


Switching on

The rear screen demisting/defrosting can only
operate when the engine is running.


)
Press this button to demist /defrost the rear
screen and (depending on version) the door
mirrors. The indicator lamp associated with
the button comes on.



Switching off

The demisting/defrosting switches off
automatically to prevent an excessive
consumption of current.


)
It is possible to stop the demisting/
defrosting operation before it is switched
off automatically by pressing the button
again. The indicator lamp associated with
the button goes off.

)
Switch off the demisting/defrosting
of the rear screen and door mirrors
as soon as appropriate, as lower
current consumption results in
reduced fuel consumption.

Gear shift indicator *
System which reduces fuel consumption by advising the driver to change up on vehicles fitted with a manual gearbox.


Operation

The system inter venes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.

- The system may suggest that you engage a
higher gear, if appropriate.
The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.

In the case of driving which makes
particular demands on the performance
of the engine (firm pressure on the
accelerator pedal, for example, when
over taking...), the system will not
recommend a gear change.
The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.



*
According to engine.
Example:


- You are in third gear.

- You press the accelerator pedal
moderately.

Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).



Stopping the vehicle

Before switching off the engine, you can
engage position P
or N
to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle, unless it is programmed
to automatic mode.

If the lever is not in position P
, when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, there is an audible signal and a
message appears.


)
Return the lever to position P
;
the audible signal stops and the
message disappears.




Operating fault

When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel
a substantial knock when changing from P

to R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


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

- if you force the lever 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 lever at N
and apply the
parking brake, unless it is programmed
in automatic mode.

Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). 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

With the electronic gearbox system,
for your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral and release the clutch
pedal,

- with the 6-speed electronic gearbox
system
, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the
gear lever into position N
.
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key. STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine star t
using the key,

- the electric parking brake is applied or
being applied,

- the engine is needed to maintain a
comfor table temperature in the passenger
compartment,

- demisting is active,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.


Special cases: STOP mode
unavailable
In this case, the "ECO"
warning lamp
flashes for a few seconds, then goes
off.

This operation is per fectly normal.

287Technical data

















Identifi cation markings
Various visible markings for the identification of your vehicle.

A.

This label is affixed to the driver's front pillar. Wheels which are fitted with 225/40 R18
tyres cannot be fitted with snow chains.
For more information, contact a CITROËN
dealer or a qualified workshop.
Low tyre pressures increase fuel
consumption. The tyre pressures must be checked
when the tyres are cold, at least once
a month.
C. Manufacturer's label.

The VIN is indicated on a self-destroying label
affixed to the driver's centre pillar. It bears the following information:


- the tyre pressures, for unladen and laden
conditions,

08 TRIP COMPUTER


Each press of the button, located at the end of the
wiper stalk, displays the different trip computer
information in succession, depending on the screen.


- the "vehicle " tab with:


●
the range, the current fuel consumption and
the distance remaining to the destination or the
Stop & Start time counter,

- the "1" tab (trip 1) with:


●
the average speed, the average consumption
and the distance travelled calculated over
trip " 1
",

- the "2" tab (trip 2) with the same information for
a second trip.

Zero reset
When the required trip is displayed, press the control
for more than two seconds.

Range:
displays the distance which can travelled with the remaining fuel
detected in the tank, based on the average fuel consumption over the last
few miles (kilometres).
This displayed value may vary signifi cantly following a change in
the vehicle speed or the relief of the route.
When the range falls below 20 miles (30 km), dashes are displayed.
After fi lling with at least 5 litres of fuel, the range is recalculated and is
displayed when it exceeds 60 miles (100 km).
If, whilst driving, dashes are displayed continuously in place of the digits,
contact a CITROËN dealer.
A FEW DEFINITIONS

Current fuel consumption:
only calculated and displayed above 20 mph (30 km/h).

Average fuel consumption:
this is the average fuel consumption since
the last trip computer zero reset.

Distance travelled:
calculated since the last trip computer zero reset.

Distance remaining to the destination:
calculated with reference
to the fi nal destination, entered by the user. If guidance is activated,
the navigation system calculates it as a current value.
