ignition Citroen DS3 2012 1.G Service Manual

The system is reactivated automaticallyat every new star t using the key.
Reactivation
This system requires a battery with a specialspecification and technology (reference numbers available from a CITROËN dealer
or a qualified workshop).
Fitting a battery not listed by CITROËN introduces the risk of malfunction of
the system. In the event of a fault with the system, the
"ECO OFF"
switch warning lamp flashes thencomes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. All of the instrument panel
warning lamps come on. It is then necessaryto switch off the ignition and star t the engine
again using the key.


Operating fault
Maintenance


Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.


The Stop & Start system makes use of advanced technology. All work
on this type of battery must be doneby a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off,accompanied by a message in the screen.

System which prevents the vehicle fromexceeding the speed programmed by the driver.
When the programmed speed limit is reached, pressing the accelerator pedal in the normalmanner no longer has any effect.
The speed limiter is switched onmanually:
it requires a programmed speed of at least
20 mph (30 km/h). The speed limiter is switched off by manual foperation of the control.
The programmed speed can be exceeded
temporaril
y by pressing the accelerator firmly.
To return to the programmed speed, simply slow down to a speed below the programmed speed.
The programmed speed remains in the memorywhen the ignition is switched off.





Speed limiter

The speed limiter cannot, in any circumstances,replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.

Cruise control
System which automatically maintains the
speed of the vehicle at the value programmed
by the driver, without any action on the accelerator pedal.
The cruise control is switched on
manually:
it requires a minimum vehicle speed of 25 mph
(40 km/h), as well as the engagement of:
- fourth gear on a manual gearbox,
- second gear on a or automatic or electronic
gearbox, in sequential mode,
-
position A
on an electronic gearbox or position D
on an automatic gearbox.
The cruise control is switched offmanuallyfor by pressing the brake or clutch pedal or
on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed
temporarily by pressing the accelerator pedal.
To return to the programmed speed, simply
release the accelerator pedal.
Switching off the ignition cancels any programmed speed value. The controls o

ProgrammingOperating faults

If there is an operating fault,
when reverse gear is engaged
this warning lamp comes on in the instrumentpanel, accompanied by an audible signal (short
beep) and a message in the multifunction screen. You can activate or deactivate the s
ystem bymeans of the multifunction screen configuration menu. The system state is memorised when
switching off the ignition.
For more information on access to the parkingsensors menu, refer to "Configuration/Vehic leparameters" in the "Multifunction screens"section corresponding to your screen.

The system will be deactivated automatically when towing a trailer or when a bicycle carrier is fitted (vehiclefitted with a towbar or bicycle carrier recommended by CITROËN).
In bad or wintry weather, ensure that the sensors are not covered with mud,frost or snow.

Checks




























Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level
Engine oil change
Refer to the servicing booklet for details of theinterval for this operation.
In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil grade
The oil must be suitable for your engine and conform to the manufacturer'srecommendations.



Brake fluid level


Changing the fl uid

Refer to the servicing booklet for details of the
interval for this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT4 standard.
Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear. The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more than30 minutes.
The check is carried out either when the ignition is switched on using the oil level indicator in
the instrument panel, or using the dipstick.
It is normal to top up the engine oil between services. CITROËNrecommends that you check the oil
level and top up if necessary, every 3 000 miles (5 000 kilometres).

Changing the coolant

The coolant does not have to be changed.


Fluid specifi cation

The coolant must conform to the
manufacturer's recommendations.



Screenwash fluid level


Fluid specifi cation

For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.

Take care when carrying out checks under the bonnet as some parts of theengine can be very hot (risk of burns).

Coolant level
Top up the level when necessary.
Th
e coolant level should be close
to the "MA X" mark but should never exceed it. When the engine is warm, the
temperature of the coolant is regulated by the fan. This can operate with the ignition off.
On vehicles which are fitted with a particle emission filter, the fan may operate after
the vehicle has been switched off, even if
the en
gine is cold.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any
work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.
