HILL START ASSIST

System which keeps your vehicle im-
mobilised temporarily (approximately
2 seconds) when starting on a gradi-
ent, the time it takes to move your foot
from the brake pedal to the accelerator
pedal.
This function is only active when:


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

- when certain conditions of gradient
are met,

- with the driver’s door closed.
The hill start assist function cannot be
deactivated.

On an ascending slope, with the ve-
hicle stationary, the vehicle is held
for a brief moment when you release
the brake pedal:



- if you are in fi rst gear or neutral with
a manual gearbox,

- if you are in position A
or M
with an
electronic gearbox.

- if you are in position D
or M
with an
automatic gearbox.


Operation


Do not leave the vehicle while it
is being held in the hill start as-
sist phase.
If you need to leave the vehi-
cle while the engine is running,
apply the parking brake manu-
ally then ensure that the parking
brake warning lamp is on (not
fl ashing) in the instrument panel.

On a descending slope, with the ve-
hicle stationary and reverse gear en-
gaged, the vehicle is held for a brief
moment when you release the brake
pedal.




Operating fault

If a fault occurs with the system, these
warning lamps come on. Contact a
CITROËN dealer or a qualifi ed work-
shop to have the system checked.

GEAR EFFICIENCY INDICATOR

System which reduces fuel consump-
tion by advising the driver to change up.
With an electronic gearbox, the system
is only active in manual mode.

Operation

Depending on the driving situation and
your vehicle's equipment, the system
may advise you to skip one (or more)
gear(s). You can follow this instruc-
tion without engaging the intermediate
gears.
The gear engagement recommenda-
tions must not be considered compulso-
ry. In fact, the confi guration of the road,
the amount of traffi c and safety remain
determining factors when choosing 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.
- You press the accelerator pedal.
Example:


- You are in third gear.

- The system may suggest that you
engage a higher gear.
The information appears in the instru-
ment panel in the form of an arrow.
On vehicles with manual gearbox, the
arrow can be accompanied by the rec-
ommended gear.

The system adapts its gear
change recommendation ac-
cording to the driving conditions
(slope, load, ...) and the de-
mands of the driver (power, ac-
celeration, braking, ...).
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

STOP & START

The Stop & Start system puts the en-
gine temporarily into standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine 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 as well as the noise
level when stationary.

Operation


Going into engine STOP mode

The "ECO"
warning lamp comes on
in the instrument panel and the en-
gine goes into standby automatically:


- with a manual gearbox
, at speeds
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal, If your vehicle is fi tted with
the system, a time coun-
ter calculates the sum of
the periods in STOP mode
d uring a journey. It resets itself to zero
every time the ignition is switched on
with the key.

- with an electronic gearbox
, at a
speed below 5 mph (8 km/h), when
you press the brake pedal or put the
gear lever into position N
. With an electronic gearbox, for
your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such
as braking, power steering, for
example.
Special cases: STOP mode
unavailable
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start
using the key,

- the electric parking brake is applied
or being applied,

- the engine is needed to maintain a
comfortable temperature in the pas-
senger compartment,

- demisting is active,

- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case, the "ECO"
warn-
ing lamp fl ashes for a few sec-
onds, then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

This operation is perfectly normal.

Deactivation

Going into engine START mode
At any time, press the "ECO OFF"

switch to deactivate the system.
This is confi rmed by the switch warning
lamp coming on accompanied by the
display of a message.
Special cases: START invoked
automatically
If the system has been deacti-
vated in STOP mode, the engine
restarts immediately. The "ECO"
warning lamp goes
off and the engine starts auto-
matically:


- with a manual gearbox
, when you
fully
depress the clutch pedal,

- with an electronic gearbox
:


●
gear lever in position A
or M
, when
you release the brake pedal,

●
or gear lever in position N
and the
brake pedal released, when you
move the gear lever to position A

or M
,

●
or when you engage reverse
gear.

For safety reasons or to ensure smooth
operation, START mode is invoked au-
tomatically when:


- you open the driver's door,

- you unfasten the driver's seat belt,

- the speed of the vehicle exceeds
15 mph (25 km/h) with a manual
gearbox or 7 mph (11 km/h) with an
electronic gearbox,

- the electric parking brake is being
applied,

- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case the "ECO"
warning
lamp fl ashes for few seconds,
then goes off.
With a manual gearbox in STOP
mode, if a gear is engaged with-
out fully depressing the clutch
pedal, a warning lamp comes
on or an alert message is dis-
played asking you to depress
the clutch pedal to restart the
engine.



Reactivation

Press the "ECO OFF"
switch again.
The system is active again; this is con-
fi rmed by the switch warning lamp go-
ing off and the display of a message.
The system is reactivated auto-
matically at every new start us-
ing the key.
This operation is perfectly normal.

CHECKS
186






Automatic gearbox
The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of
the level checking interval for
this component.
















Electric parking brake

This system does not require
any routine servicing. However,
in the event of a problem,
have the system checked by
a CITROËN dealer or a qualifi ed work-
shop.





















Manual parking brake

















Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
those in the braking system,
CITROËN selects and offers
very specifi c products.
After washing the vehicle, damp-
ness, or in wintry conditions, ice
can form on the brake discs and
pads: braking effi ciency may be
reduced. Make light brake ap-
plications to dry and defrost the
brakes.
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be done by
a CITROËN dealer or a qualifi ed work-
shop.
















Brake pads

Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short distances. It
may be necessary to have the
condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.


Brake disc wear

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop.
For more information, refer to the "Electric
parking brake - Operating faults" section.

PRACTICAL INFORMATION
207
When your vehicle's battery is dis-
charged, the engine can be started using
a slave battery (external or on another
vehicle) and jump lead cables.












Starting using another battery




12 V BATTERY

The battery is located under the bonnet.
For access to the (+) terminal:



release the bonnet using the interior
lever, then the exterior safety catch,


raise the bonnet and secure it with
its stay,


lift the plastic cover for access to the
(+) terminal.


Access to the battery







The presence of this label, in par-
ticular with the Stop & Start sys-
tem, indicates the use of a 12 V
lead-acid battery with special
technology and specifi cation;
the involvement of a CITROËN
dealer or a qualifi ed workshop is
essential when replacing or dis-
connecting the battery.
Procedure for starting the engine us-
ing another battery or charging a dis-
charged battery.

After refi tting the battery, the
Stop & Start system will only be
active after a continuous period
of immobilisation of the vehicle,
a period which depends on the
climatic conditions and the state
of charge of the battery (up to
about 8 hours).
First check that the slave battery
has a nominal voltage of 12 V
and a capacity at least equal to
that of the discharged battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) termi-
nal when the engine is running.
Before doing any work
Immobilise the vehicle: apply the
parking brake, put the gearbox
in neutral, then switch off the ig-
nition.
Check that all electrical equip-
ment is switched off.
