2015.5 Citroen DS4 RHD tow

Lateral airbags
System which protects the driver and front
passenger in the event of a serious side impact
in order to limit the risk of injury to the chest,
between the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, door side.deployment
A lateral airbag is deployed unilaterally in the
event of a serious side impact applied to all or
part of the side impact zone B, perpendicular
to the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The lateral airbag inflates between the hip and
shoulder of the front occupant of the vehicle
and the corresponding door trim panel.
Impact detection zones
A. Front impact zone.
B. Side impact zone.

Curtain airbags
System which contributes towards improving the
protection of the driver and passengers (with the
exception of the rear centre passenger) in the
event of a serious side impact in order to limit
the risk of injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
deployment
The curtain airbag is deployed at the same
time as the corresponding lateral airbag in the
event of a serious side impact applied to all or
part of the side impact zone B, perpendicular
to the longitudinal centreline of the vehicle on a
horizontal plane and directed from the outside
towards the inside of the vehicle.
The curtain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Safety

When towing
distribution of loads
F 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 per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F 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.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f 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, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
For more information on weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Electric parking brake
The electric parking brake has two operating
modes:
-
A
utomatic application / release
A

pplication is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),
-

M
anual application / release
T

he parking brake can be applied /
released manually by pulling control
lever


A. Do not place any object (packet of
cigarettes, telephone...) between the
gear lever and the electric parking
brake control lever. It is recommended that you do not
apply the parking brake in very cold
conditions (ice) and during towing
(breakdown, caravan...). Deactivate the
automatic functions and release the
parking brake manually.
If this warning lamp comes on in
the instrument panel, the automatic
mode is deactivated.
Programming the mode
Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release when
you press the accelerator can be deactivated. Activation / deactivation is done
using the vehicle configuration
menu; refer to the section covering
the configuration of your vehicle's
systems.
The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible signal and a message is
displayed if the parking brake is not applied.

With the ignition on or the engine running, to
release the parking brake, press on the brake
pedal or the accelerator, pull then release
control A .
Manual release
Before leaving the vehicle, ensure
that parking brake warning lamp in the
instrument panel is on fixed, not flashing.
Manual application
With the vehicle stationary, to apply the parking
brake whether the engine is running or off, pull
control lever A .
The application of the parking brake is
confirmed by: -
i

llumination of the braking warning
lamp and of the P warning lamp in
the control lever A ,
-

d
isplay of the message "Parking
brake on".
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case
of an automatic gearbox with the gear selector
in position P . The full application of the parking brake is
confirmed by:
-

t
he braking warning lamp and
the P warning lamp in the control
lever A going off,
-

d
isplay of the message "Parking
brake off ".
If you pull control lever A without
pressing the brake pedal, the parking
brake will not be released and a
warning lamp will come on in the
instrument panel.
Maximum application
If necessary, you can make a maximum
application of the parking brake. This is
obtained by means of a long pull on the control
lever A , until you see the message "Parking
brake on maximum" and a beep is heard.
Maximum application is essential:
-

i
n the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,
-

w
hen the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing),
In the case of towing, a loaded vehicle
or parking on a gradient, make a
maximum application of the parking
brake then turn the front wheels
towards the pavement and engage a
gear when you park.
After a maximum application, the
release time will be longer.

Operating fault
In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.The system may suffer temporary
interference in certain weather
conditions (rain, hail...).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud,
ice or snow.
Take care not to cover the warning
zone in the door mirrors or the
detection zones on the front and rear
bumpers with adhesive labels or other
objects; they may hamper the correct
operation of the system.
