ignition Citroen DS3 2011 1.G Service Manual

The system is reactivated automatically
at every new star t using the key.


Reactivation

This system requires a battery with a special
specification 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 malfunction with the system,
the "ECO OFF"
switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the
vehicle may stall. It is then necessary to switch
off the ignition and star t the engine again using
the key.


Operating fault
Maintenance

Before working under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from
automatic operation of START mode.
The Stop & Star t system makes use of
advanced technology. All work on this
battery must be done by a CITROËN
dealer or a qualified workshop. Press 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.

169Driving
System which prevents the vehicle from
exceeding the speed programmed by the driver.
When the programmed speed limit is reached,
pressing the accelerator pedal in the normal
manner no longer has any effect.
The speed limiter is switched on
manually:
it requires a programmed speed of at least
20 mph (30 km/h).
The speed limiter is switched off
by manual
operation of the control.
The programmed speed can be exceeded
temporarily 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 memory
when 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 part of the driver.
The controls of this system are grouped
together on stalk A

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:


- four th gear on a manual gearbox,

- second gear on a SensoDrive or automatic
gearbox, in sequential mode,

- position A
on a SensoDrive gearbox or
position D
on an automatic gearbox.
The cruise control is switched off
manually
or 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 of this system are grouped
together on stalk A

Programming
Operating faults

If there is an operating fault, when
reverse gear is engaged this
warning lamp comes on in the instrument panel,
accompanied by an audible signal (shor t beep)
and a message in the multifunction screen. You can activate or deactivate the system by
means of the multifunction screen configuration
menu. The system state is memorised when
switching off the ignition.
For more information on access to the parking
sensors menu, refer to "Configuration/ Vehicle
parameters" 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 (vehicle
fitted 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.

183Checks




























Checking levels

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


Oil level


Engine oil change

Refer to the Maintenance and Warranty Guide
for details of the inter val 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's
recommendations.



Brake fluid level


Changing the fl uid

Refer to the Maintenance and Warranty Guide
for details of the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to the
manufacturer's recommendations and meet the
DOT4 standard.
The brake fluid level should be close
to 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 than
30 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 ser vices. CITROËN
recommends 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 water.



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



Coolant level

Top up the level when necessary.
The 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 par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the engine 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.

Removing a wheel


Parking the vehicle

Immobilise the vehicle where it does
not block traffic: the ground must be
level, stable and not slippery.
