engine Citroen DS3 2012.5 1.G Service Manual

Gear effi ciency indicator *
Operation
The system intervenes only when driving economically.
Depending on the driving situation and your
vehicle's equipment, the s
ystem 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 trafficand 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.

- The s
ystem may suggest that you engage a
higher gear, if appropriate.
The in
formation appears in the instrument panel in the form of an arrow accompanied bythe suggested gear.


In the case of driving which makesparticular demands on the performance of the engine (firm pressure on theaccelerator pedal, for example, whenover taking...), the system will notrecommend a gear change. The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.

Driving

Creep function
(6-speed electronic gearbox
system)
This function allows the vehicle to be manoeuvred more easily at low speeds (whenparking, in traffic jams...).
With the gear lever in position A
, Mor R, the vehicle moves as soon as you take your foot off the brake pedal
, at low speed and
with the engine at idle.
Automated mode
AUTOand the gear engaged appear
in the instrument panel.
The gearbox then operates in auto-adaptive
mode, without an
y action on the par t of the
driver. It continuously selects the most suitablegear taking account of:
- optimisation of fuel consumption,
- drivin
g style,
- road conditions,
- vehicle load. For optimum acceleration, when overtaking another vehicle for example, press theaccelerator pedal fully down, beyond the pointof resistance.
You can change mode at any time bymoving the gear lever from Ato M
or the other way round.

The creep function may be temporarilyunavailable if the clutch temperature istoo high or the slope too steep.

Do not leave children unsuper visedinside the vehicle when the engine is running.
)
Select position A.
Never select neutral (position N) whenmoving.


Te m p o r a ry control of gear
changing

You can temporarily take over control of gear changes using the steering mounted "+"and "-"
control paddles: if the engine speed
allows, the gear change is carried out.
This function allows you to anticipate certainsituations such as over taking another vehicleor approaching a bend.
After a few moments without any action on the
paddles, the gearbox resumes control of gear changing automatically.

if the engine speed permits.
It is not necessary to release the accelerator pedal during gear changes. When braking or slowing down, the gearboxchanges down automatically so that the vehiclepicks up in the right gear.
Under full acceleration, the change up willnot take place unless the driver operates the gear lever or steering mounted control paddle(unless the engine is close to its maximumspeed).

Reverse

To e ngage reverse, the vehicle must be
immobilised with your foot on the brake. ) Select position R.


Stopping the vehicle

Before switching off the engine:


- change to position N
to be in neutral, or

- leave the vehicle in gear; in this case the
vehicle cannot be moved.
Manual mode
)Select position M.
The gears engaged appear in
succession in the instrument panel.
You can change mode at any time bymoving the gear lever from Ato Mor the other way round.
Never select neutral (position N ) when moving.
There is an audible signal onengagement of reverse.
For all parking situations, you mustapply the parking braketo immobilise the vehicle.

When immobilising the vehicle with theengine running, you must put the gear lever into neutral (position N)
.

Before doing anything under the bonnet, ensure that the gear lever is inneutral (position N ) and that the parkingbrake is applied. At low speed, i
f reverse gear is requested,
the Nwarning lamp flashes and the gearbox goes into neutral automatically.
To e ngage reverse, put the gear lever into
position N , then to position R.

Operating fault
With the ignition on, if this warninglamp comes on and AUTOflashes,
accompanied by an audible signal and a
message in the multifunction screen, this
indicates a gearbox fault. Have it checked by a CITROËN dealer or a qualified workshop.

Four-speed automatic gearbox which offers a choice between the comfor t of fully automatic
operation, enhanced by spor t and snow programmes, or manual gear changing.
Therefore, four driving modes are offered:
- automaticoperation for electronic management of the gears by the gearbox, -sport
programme for a more dynamic style
of driving,-snowprogramme to improve driving when
traction is poor, - manualoperation for sequential changing
of the gears by the driver.

Automatic operation
)Select position Dfor automaticchanging
of the four gears.
The gearbox then operates in auto-adaptive mode, without any inter vention 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 downautomatically to provide efficient enginebraking.
If you release the accelerator sharply, thegearbox will not change to a higher gear for safety reasons.
Never select position N while the vehicle is moving.
Never select positions Por R
unless the vehicle is completely stationary.


Sport and snow
programmes

These two special programmes supplement the
automatic operation in very specific conditionsof use.

Sport programme "S"

Press button "S", after star ting the engine.
The gearbox automatically favours a dynamic
style of driving.
S appears on the instrument panel.


Snow programme " 7"

Manual operation
Ddisappears and the gears engaged appear in succession on the
instrument panel.
If the en
gine speed is too low or
too high, the gear selected flashes for a fewseconds, then the actual gear engaged isdisplayed.
It is possible to change from position D(automatic) to position M
(manual) at any time.
When the vehicle is stationary or moving
ver
y slowly, the gearbox selects gear M1automatically.
The spor t and snow programmes do not
operate in manual mode.
Invalid value during manualoperation
)Select position M for sequential
changing
of the four gears. )Push the lever towards the + sign
to change up a gear.)Pull the lever towards the - sign to changedown a gear.
It is only possible to change from one gear to
another if the vehicle speed and engine speedpermit; other wise, the gearbox will operate
temporarily in automatic mode. This s
ymbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can engageposition Por Nto place the gearbox in neutral. In both cases, apply the parking brake
to immobilise the vehicle. When the i
gnition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message in the
multifunction screen, indicates a gearbox fault.
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 Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
wor
kshop as soon as possible.

Operating fault
If the lever is not in position P,P
when the driver's door is opened or approximately 45 seconds after the ignition is switched off, a message appears in the multifunction screen. )Return the lever to position P
; the message disappears.

There is a risk of damage to thegearbox:


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

- if you force the movement of the gear lever from the Pposition to another position when the battery is flat.
To r e d u c e fuel consumption when at a prolonged standstill with the enginerunning (traffic jam...), put the gear lever in the Nposition and apply the parking brake.
