check engine light Citroen C4 DAG 2013.5 2.G Owner's Manual

27

Switch off the headlamps and front
foglamps when the level of light does
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, if you avoid connecting
your multimedia devices (fi lm, music,
video game...), you will contribute to-
wards limiting the consumption of elec-
trical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.



Limit the causes of excess
consumption

Spread loads throughout the vehicle;
place the heaviest items in the bottom
of the boot, as close as possible to the
rear seats.
Limit the loads carried in the vehicle
and reduce wind resistance (roof bars,
roof rack, bicycle carrier, trailer...). Use
a roof box in preference.
Remove roof bars and roof racks after
use.

At the end of winter, remove snow
tyres and refi t your summer tyres.



Observe the recommendations
on maintenance

Check the tyre pressures regularly,
when cold, referring to the label in the
door aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the
tyres on any trailer or caravan.

Have your vehicle serviced regularly
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.



When refuelling, do not continue after
the third cut-off of the nozzle to avoid
any overfl ow.


At the wheel of your new vehicle, it is only
after the fi rst 1 800 miles (3 000 kilometres)
that you will see the fuel consumption set-
tle down to a consistent average.

Manual operation




Select position M
for sequential

changing of the six gears.


Push the lever towards the +
sign to
change up a gear.


Pull the lever towards the -
sign to
change down a gear.
It is only possible to change from one
gear to another if the vehicle speed and
engine speed permit; otherwise, the
gearbox will operate temporarily in au-
tomatic mode.

D
disappears and the gears
engaged appear in succes-
sion in the instrument panel.
If the engine speed is too low
or too high, the gear selected
fl ashes for a few seconds, then the ac-
tual gear engaged is displayed.
It is possible to change from position D

(automatic) to position M
(manual) at
any time.
When the vehicle is stationary or mov-
ing very slowly, the gearbox selects
gear M1
automatically.
The sport and snow programmes do
not operate in manual mode.
Invalid value during manual
operation
This symbol is displayed if a
gear is not engaged correctly
(selector between two posi-
tions).



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.


You risk damaging the gearbox:


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

- if you force the lever from
position P
to another position
when the battery is fl at. 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 gear-
box 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), lo-
cal speed restrictions permitting.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
This warning lamp may also come on if
a door is opened.

Operating fault

To reduce fuel consumption
when stationary for long periods
with the engine running (traffi c
jam...), position the gear lever
at N
and apply the parking brake,
unless it is programmed in auto-
matic mode.

PRACTICAL INFORMATION
220








TOWING A TRAILER


We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or installation of a bicycle carrier,
with additional lighting and signalling.

Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer.
Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.



Driving advice


Distribution of loads



Distribute the load in the trailer so
that the heaviest items are as close
as possible to the axle and the nose
weight approaches the maximum
permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.

Side wind



Take into account the increased
sensitivity to side wind.


Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.



To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.



If the warning lamp and the
STOP
warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.


Braking
Towing a trailer increases the braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres




Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.



Lighting



Check the electrical lighting and sig-
nalling on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
