2011 Citroen DS4 tow

Electric parking brake


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

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

- Manual Application/Release

The 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 brake is not applied.

193Driving
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:


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

- display of the message
"Handbrake 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 lever in
position P
. The full application of the parking brake is
confirmed by:


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

- display of the message
"Handbrake 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 "Handbrake
on maximum" and a beep is heard.

Maximum application is essential:



- in 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,

- when 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.

With the vehicle stationary, the parking brake
is automatically applied when the engine is
switched off.



Automatic application,
engine off

In the case of towing, a loaded vehicle
or parking on a gradient, turn the front
wheels towards the pavement and
engage a gear when you park.

Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed (not
flashing).
Never leave a child alone inside the
vehicle with the ignition on, as they
could release the parking brake.


- illumination of the braking warning
lamp and of the P

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 aler ts (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.



)
To deactivate the system, press this button
again; the warning lamp goes off.
The state of the system remains in memory on
switching off the ignition.
The system is automatically
deactivated when towing with a towbar
approved by CITROËN.

to the "CRUISE"
position: the
cruise control mode is selected but is not
switched on (Pause).

)
Set the programmed speed by accelerating
to the required speed, then press button 2
or 3
(e.g.: 70 mph (110 km/h)); the cruise
control system is activated (ON).
You can then change the programmed speed using buttons 2
and 3
:


- by + or - 1 mph (km/h) = shor t press,

- in steps of + or - 5 mph (km/h) = maintained press.
If storing speeds is available and activated on your vehicle, the
programmed speed will stop at the closest stored speed; refer to the
corresponding section.


)
Stop the cruise control system by pressing button 4
: this is
confirmed in the screen (Pause).

)
Switch on the cruise control again with another press on button 4
.



Exceeding the programmed speed

Intentional or unintentional exceeding of the programmed speed results in
flashing of this speed in the screen.
Return to the programmed speed, by means of intentional or unintentional
deceleration of the vehicle, automatically cancels the flashing of the speed.


Exiting cruise control mode



)
Turn dial 1
to the "0"
position: the cruise control mode is deselected.
It disappears from the screen.



Operating fault

In the event of a cruise control malfunction,
the speed is cleared resulting in flashing of the
dashes.
Have it checked by a CITROËN dealer or a
qualified workshop.
When the cruise control is switched on,
be careful if you maintain the pressure
on one of the programmed speed changing
buttons: this may result in a very rapid
change in the speed of your vehicle.
Do not use the cruise control on slippery
roads or in heavy traffic.
On a steep descent, the cruise control will
not be able to prevent the vehicle from
exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached or
maintained.
To avoid any risk of jamming of the pedals:


- ensure that the mat is positioned
correctly,

- never fit one mat on top of another.

Front parking sensors
Operating fault

In the event of a malfunction of
the system, when reverse gear
is engaged this warning lamp
is displayed in the instrument panel and/or a
message appears in the screen, accompanied
by an audible signal (shor t beep).
Contact a CITROËN dealer or a qualified
workshop. In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no fur ther obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).


The function will be deactivated
automatically if a trailer is being towed
or a bicycle carrier is fitted (vehicle
fitted with a towbar or bicycle carrier
recommended by CITROËN).

In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dir ty.
When the vehicle is moving at a speed
below 6 mph (10 km/h), cer tain sound
sources (motorcycle, lorry, pneumatic
drill, etc.) may trigger the audible
signals of the parking sensor system.


Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by pressing this button.
The indicator lamp in the button comes on.
Pressing this button again reactivates the
function. The indicator lamp in the button goes
off.

The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.

Electric parking brake

This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.
For more information, see "Driving - Electric
parking brake - § Operating faults".















Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation
of units as impor tant as the braking
system, CITROËN selects and offers
very specific products.
To avoid damaging the electrical units,
the use of a high pressure washer
in the engine compar tment is strictly
prohibited
.



Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Manual parking brake

If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two ser vices.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
















Brake pads

Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It may be necessary to
have the condition of the brakes checked,
even between vehicle ser vices.
Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake
pads are worn.
