engine Citroen DS5 RHD 2012.5 1.G Service Manual

Emergency braking
In the event of a failure of the main servicebrake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuouspull on the control lever A
will stop the vehicle.
The Dynamic Stability Control system provides stability during emergency braking.
If the emer
gency braking malfunctions, themessage "Parking brake control faulty" will be
displayed.
)Take the vehicle blocks and the release
device, located under the boot carpet.
)On sloping ground, secure the vehicle by placing chocks in front or behind the front
wheels, on the falling side of the slope.
The emergency braking must only be used in exceptional circumstances.
I
f a failure of the DSC system is
signalled by the illumination of this
warning lamp, then braking stability is
not guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"actions on the control lever A.








Emergency release

In the event of the electric parking brake
malfunctioning or the battery running flat, an emergency manual device can release the
parkin
g brake. ) Immobilise the vehicle:


- by engaging first gear (manual gearbox),

- with the engine running, position P(automatic gearbox) or Mor R
(electronicgearbox system).)
Switch off the engine then switch the
ignition on. If it is impossible to immobilise
the vehicle, do not operate the control and
contact a CITROËN dealer or a qualified
workshop urgently.

Driving

For safety reasons, you must contact a
CITROËN dealer as soon as possible toreplace the protective cover. Ta k e care not to allow moisture or dust in the proximity of the protective cover.
Following an emergency unlocking,immobilisation of the vehicle is nolonger guaranteed once the manualemergency release has been deployedand the manual control does not allowthe re-application of your parking brake. Take no action, either on the control lever A, or stopping or star ting theengine while the release device is engaged.
To r e - e ngage the electric parking brake(after correction of the fault or batteryproblem), make a long pull on the
control lever A
until the parking brake warning lamp in the instrument panel flashes then make a second long pull until this warning lamp comes on fixed. Front left seat moved back full
y.
)Slide the front left-hand seat back as far aspossible.)Raise the pre-cut zone Bin the carpetunder the seat.)Pierce the protective cover Con the tube Dwith the release device (located in the
boot). )Place the release device in the tube D.)Turn the release device clockwisemaking several dozen turns.
For safety reasons
, it is essential
to
continue turning the device as far as it will go.
The parking brake is released.
) Remove the release device and stow it. )
The operation of the parking brake reinitialises after the ignition is switched off
then on again. If the reinitialisation of the
parking brake proves impossible, contact a
CITROËN dealer or a qualified workshop.) The (subsequent) time required for
application may be longer than during
normal operation.

Special situations

In the event of a malfunction of the parking brake in the on positionor a battery failure,manual release remains possible. To ensure correct operation, and soyour safety, the number of successive applications and releases of the parking brake is limited to eight cycles.
If used excessively, you are aler ted bythe message "parking brake faulty" and a flashing warning lamp.

In some circumstances (engine start...),the parking brake may adjust the level of application itself. This is normal operation.
To m o v e your vehicle a few centimetreswithout starting the engine, with the ignition on, press the brake pedal and release the parking brake by pullingthen releasingthe control lever A

Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) whenstarting on a gradient, the time it takes to move your foot from the brake pedal to the
accelerator pedal.
This s
ystem only operates when:


- the vehicle is completely stationary, with your foot on the brake pedal,

- in par ticular conditions on a slope,

- with the driver’s door closed.
The hill star t assist system cannot be
deactivated.
On an ascending slope, with the vehiclestationary, the vehicle is held for a momentarily when you release the brake pedal:- provided you are in first gear or neutral on
a manual gearbox,
- provided
you are in position A
or M
on an electronic gear control gearbox,
- provided you are in position D
or M
on an
automatic gearbox.
Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, thevehicle is held momentarily when you
release the brake pedal.

Do not exit the vehicle while it is beingheld in the hill star t assist phase.
If you need to exit the vehicle withthe engine running, apply the parkingbrake manually then ensure that theparking brake warning lamp (and the warning lamp P
in the lever of theelectric parking brake) are on fixed (notflashing).


Operating fault

If a fault in the system occurs, these warning
lamps come on. Contact a CITROËN dealer or a qualified workshop to have the systemchecked.

Only engage reverse gear when the vehicle is stationary with the engine at idle.
As a safety precaution and to facilitatestarting of the engine, always select neutral.

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


Operation
The system intervenes 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 mustnot be considered compulsory. In fact, the configuration of the road, the amount of traffic
and safety remain determining factors whenchoosing 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.

*
Accordin
g to engine. -
You are in third gear.
Example:
-
You press the accelerator pedalmoderately.
-
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 b
y
the suggested gear.

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


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.

Automatic operation
)
Select position D
for automatic
changing
of the six gears.
The gearbox then operates in auto-adaptive
mo
de, without any intervention on the par t of the driver. It continuously selects the most suitable gear according to the style of driving,
the profile of the road and the load in the
vehicle.
For maximum acceleration without touching
the lever, press the accelerator pedal down
fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide efficient engine
braking.
I
f you release the accelerator sharply, the gearbox will not change to a higher gear for safety reasons.

Manual operation
)Select position M
for sequentialchanging
of the six gears.)Push the lever towards the + sign to change up a gear.
)Pull the lever towards the -
sign to change
