HILL START ASSIST
System which holds your vehicle tem-
porarily (approximately 2 seconds)
when starting on a slope, 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 station-ary, with your foot on the brake
pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system oc-
curs, these warning lamps come on.
Contact a CITROËN dealer to have
the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held for a brief moment when you
release the brake pedal:
- provided you are in fi rst gear or neutral on a manual gearbox,
- provided you are in A or M with
the electronic gearbox system,
- provided you are in D or M on an
automatic gearbox.
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held
momentarily when you release
the brake pedal.
Do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the vehicle with
the engine running, manually apply
the parking brake and ensure that
the warning lamp P (red) in the in-
strument panel is on (not fl ashing).

sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
6-SPEED ELECTRONIC GEARBOX SYSTEM
The 6-speed electronic gearbox of-
fers a choice between the comfort of
fully automatic operation or the driving
pleasure of manual gear changing.
You have a choice of two driving
modes:
-

automatic mode for automatic con-
trol of the gears by the gearbox,
- sequential mode for manual
changing of the gears by the
driver.

 automatic mode: selector lever 2
in position A .

 manual mode: selector lever 2 in
position M .
In automatic mode, instant manual
operation is possible any time you
operate one of the paddles 1 .

Acceleration
For optimum acceleration (e.g. to
overtake another vehicle), simply
press the pedal beyond the point of
resistance at the end of its travel, by
pressing down fi rmly.
Vehicle stationary, with the
engine running
In the event of a prolonged stop with
the engine running, the gearbox
changes automatically to neutral N . Stopping the vehicle
Before stopping the engine, you can
choose:

 to leave the vehicle in neutral;
move the selector lever to posi-
tion N .

 to leave the vehicle with a gear
engaged ( R , A or M ); place the
selector in the chosen position
prior to stopping the engine. In
this case, the vehicle cannot be
moved.
In all cases, it is essential to apply
the parking brake. Check that the
parking brake warning lamp is on in
the instrument panel.
Do not use the accelerator to
hold your vehicle on a gra-
dient. Use either the brake
pedal or the parking brake.
Before doing anything in the en-
gine compartment, check that the
selector lever is in neutral N .
The paddles cannot be used to se-
lect neutral or reverse gear, or to exit
reverse gear.
- If the vehicle stops or reduces
speed (for example when ap-
proaching a stop sign), the gear-
box changes down automatically,
to fi rst gear if needed.
- In manual mode, it is not neces- sary to release the accelerator
completely during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it.
- For safety reasons, depending on the engine speed, a change
down may be performed auto-
matically.
In situations of high engine
speeds (heavy accelera-
tion), a change up will not
occur unless the driver op-
erates the paddle.

In the event of a malfunction with
the system, the "ECO OFF" switch
warning lamp fl ashes then comes
on continuously.
Have it checked by a CITROËN
dealer.
In the event of a fault in STOP mode,
the vehicle may stall. It is then nec-
essary to switch off the ignition and
start the engine again using the key. Maintenance
Operating fault
Before working under the
bonnet, deactivate the Stop
& Start system to avoid any
risk of injury resulting from auto-
matic operation of START mode.
This system requires a battery with
a special specifi cation and technology
(reference numbers available from
CITROËN dealers).
Fitting a battery not listed by
CITROËN introduces the risk of
malfunction of the system.
The Stop & Start system makes use of advanced technology.
Specialist knowledge is needed
for any work on the system, which can
only be assured by CITROËN dealers.

Deactivation
Press on button 3 .
This action causes the
information "OFF" to
appear on the instru-
ment panel screen.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel.
Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again. Return to normal driving

 By moving the control 1 from po-
sition "LIM" to position 0 .

 By the engine stopping.
The speed previously chosen is still
memorised. Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
acceleration) then the speed fl ashes.
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing of the speed limiter.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.

Reactivation

 By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.

 By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display.
Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary.
Return to normal driving Operating fault

If there is a malfunction, a mes-
sage will display accompanied by
an audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.

be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level
Engine oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Changing the fl uid
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Changing the coolant
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is
regulated by the fan. This can oper-
ate with the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, 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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited. When working under the
bonnet, take care, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fluid level The power steering fl uid
level should be close to the
"MAX" mark. Unscrew the
cap, with the engine cold, to
check the level.
