Gearbox and steering wheel
- with a manual gearbox , with the vehicle
stationary, put the gear lever into neutral,
then release the clutch pedal,
- with an electronic gearbox , with the
vehicle stationary, hold the brake pedal
down or put the gear lever into position N . Special cases: STOP mode unavailable
The STOP mode is not invoked when:
- the driver's door is open,
- the driver's seat belt is not fastened,
- the heated rear screen is on,
- the windscreen wiper is on fast wipe,
- reverse gear is engaged,
- some special conditions (battery
charge, engine temperature, particle
filter regeneration, braking assistance,
ambient temperature...) where the engine
is needed to assure control of a system.
In this case, a message appears
in the instrument panel screen,
accompanied by the "S" warning
lamp, which flashes for a few
seconds, then goes off.

This operation is perfectly normal.
STOP & START
The Stop & Start system puts the engine
temporarily into standby - STOP mode -
during stops in the traffic (red lights, traffic
jams, or other...). The engine restarts
automatically - START mode - as soon as
you want to move off. The restart takes
place instantly, quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions and offers the comfort of
complete silence when stationary.
Operation
Going into engine STOP mode
The "S" warning lamp comes on
in the instrument panel and the
engine goes into standby: Automatic stopping of the engine is
only possible after the vehicle has
exceed a speed of about 6 mph (10 km/h),
to avoid repeated stopping of the engine
when driving slowly.
In the STOP mode Stop & Start, hill
start assist is inactive.
Never leave your vehicle with out first
turning off the ignition with the key.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key.

Checks
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for the details of the level checking
interval for this component.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet which
correspond to your vehicle's engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited. Particle filter system (1.3 HDi 75)
An addition to the catalytic converter, this
fi lter makes an active contribution to the
preservation of air quality by the retaining of
the unburnt pollutant particles. Black exhaust
fumes are thus no longer emitted.
This fi lter, fi tted to the exhaust system,
accumulates particles of soot. The engine
control unit manages the automatic
periodic elimination of the soot particles
(regeneration).
the regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions of the
vehicle. During this phase, you may notice
some unusual phenomena - increased idling
speed, cooling fan running, increase in smoke
and higher exhaust gas temperature - which
does not affect the operation of the vehicle or
the environment.
After prolonged idling or driving at very low
speeds, you may occasionally notice water
vapour being emitted from the exhaust when
accelerating. This is of no consequence to the
running of the vehicle or to the environment.
Saturation/Regeneration
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
This alert tells you that the
particle filter is starting to fill up (in
conditions of urban driving of exceptionally
long duration: low speeds, traffic jams etc.).
To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
if possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust/particle filter system.
Have it checked by a CITROËN dealer.
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for details of
the checking interval for this component.
Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle fi lter, it is
recommended that you do not park the vehicle
over infl ammable materials (grass, dry leaves,
pine needles, ...) so as to avoid any risk of fi re.
