Invalid value in manual operation
This symbol is displayed i
f a gear is not engaged correctly (gear selector
between two positions). You can temporaril
y take control of gear changes using the "+
" and "-" steering mounted control paddles. If the engine speed allows, the
instruction to change gear is acted on.
This function allows you to anticipate cer tain situations such as overtaking another vehicle or
approaching a bend.
After a few moments with no action on the control paddles, the gearbox manages thegears automatically again.

Te m p o r a ry manual control of the gears


Manual mode
Dand the gear engaged are displayed in the instrument panel.
The gearbox operates in auto-active
mode, without any action from the driver. It continuously selects the most appropriate gear
according to the following conditions:


- optimisation of fuel consumption,

- drivin
g style,

- relief of the road,

- vehicle load.


Automated mode
)
Select position D.

For maximum acceleration, without touching
the gear selector, press the accelerator fully
down (kick down). The gearbox changes down
automatically and maintains the gear selected
until the maximum en
gine speed is reached.
When braking, the gearbox changes down
automatically for more effective engine braking.
When you take your foot of the accelerator pedal suddenly, the gearbox does not change
up, so as to improve safety.
) Select position M.)
Use the " + " and "- " steering mounted
control paddles to change gear.
The gears engaged are displayed successively
in the instrument panel.
When stationar
y or at very low speed, the gearbox automatically engages 1st
gear.
In manual mode, it is not necessary to release
the accelerator pedal when changing gear.
The change from one gear to another is onlyeffected if the conditions of vehicle speed andengine speed allow; other wise the automatic
laws of operation are imposed temporarily.
If the engine speed is too high or too low,
the display of the gear selected flashes for a few seconds, then the new gear engaged is displayed.
It is possible to change mode at any time, by moving the gear selector from D
to Mor the other way round.

158
Driving
Before switching off the engine, you canchange to position P or Nto be in neutral.
In either case, appl
y the parking brake to
immobilise the vehicle, unless it is programmed
in automatic mode.
If the lever is not in position P, on opening the Pdriver's door or approximately 45 seconds after switching off the ignition there is an audible signal and a message appears: )move the gear selector to position P; the audible signal stops and the message
disappears.

Operating fault
Whenever parking, you must apply the parking
brake to immobilise the vehicle, if automatic
operation has been deactivated.
Parking the vehicle

In all circumstances, ensure that thegear selector is in position Pbefore leaving your vehicle.In th
e event of a fault with the
gearbox, the ser vice warning lamp
comes on in the instrument panel, accompanied by a message and anaudible signal.

In this case the gearbox goes into back-up
mode and stays in 3rdgear. You may then feel
a noticeable jolt when going from P to Rand from N
to R
. This jolt does not present any risk
to the gearbox.
Do not exceed 60 mph (10 0 km/h) while also
observing legal speed limits.
Have it checked by a CITROËN dealer or aqualified workshop.

Stop & Start
Operation
Going into engine STOP mode
The "ECO"
warning lamp comes onin the instrument panel and the enginegoes into standby automatically:
-with a manual gearbox
, at speeds below
12 mph (20 km/h), when you place the gear lever in neutral, and you release the clutch pedal, - with an electronic gearbox,at speeds
below 5 mph (8 km/h), when you press the
brake pedal or place the gear selector lever in position N ,
- with an automatic gearbox,
with the
vehicle stationary, when you press the brake pedal or place the gear selector lever in position N.If your vehicle is fitted with the system, a timecounter calculates the sum of the periods in STOP mode during a journey. It resets itself to
zero every time the ignition is switched on with
the STA R T/STOP button.
Never refuel with the engine in STOPmode; you must switch off the ignition with the STA R T/STOP button.
For your comfor t, during parkingmanoeuvres, 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 for example, braking, power steering...


Special cases: STOP mode not
available
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 usingthe START/STOP button,

- the electric parking brake is applied or being applied,

- the engine is needed to maintain acomfor table temperature in the passenger compartment,

- demistin
g is active,

- some special conditions (battery charge, engine temperature, braking assistance,ambient temperature...) where the engine isneeded to assure control of a system.

In this case, the "ECO"
warning lampflashes for a few seconds then goesoff.This operation is per fectly normal.
The Stop & Star t system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Star t system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.

Reactivation

Press this button again.


Operating fault

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.
Depending on version, an alert message may
also be displa
yed, asking you to place the gear
selector lever in position Nand put your foot on
the brake pedal.
It is then necessar
y to switch off the ignition
and star t the engine again using the "START/STOP" button.In th
e event of a fault with the system, this warning lamp comes
on continuously.
The system is active again; this is confirmed by the indicator lamp in thebutton going off and illumination of
this symbol.
The Stop & Start system makes use of advanced technology. For any work onthe system go to a qualified workshop with the skills and equipment required, which a CITROËN dealer is able toprovide.

Before doing anything under the bonnet,deactivate the Stop & Start system toavoid any risk of injury resulting fromautomatic operation of STA R T m o d e .


Maintenance

This system requires a 12 V battery with a special specification and technology (reference numbers available from CITROËN dealers).
Fitting a battery not listed by CITROËN introduces the risk of malfunction of
the system.
For charging, use a 12 V charger and do not
reverse the polarity.

Active cruise control
This systems allows, in addition to maintainingyour vehicle's speed at a value that you have defined, the inter-vehicle time you have
selected between your vehicle the the one ahead to be maintained (2 seconds by default,
on activating the function).

Principles of operation

Using a radar with a range of about 100 metres,located at the front of the vehicle, this system
detects a vehicle running in front of your
vehicle.
It automatically adapts the speed of the vehicle
to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of your vehicle using just engine braking (as if thedriver had pressed the "- " button).
If your vehicle is too close to or approaching tooquickly the vehicle in front, the cruise control
is automatically deactivated. The driver is then
aler ted by an audible signal, accompanied by a message.
If the vehicle in front accelerates or changeslane, the active cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator to
the left (left hand drive) or the right (right hand
drive), to over take a slower vehicle, the active cruise control allows your vehicle to temporarily
approach the vehicle in front to assist the
over takin
g manoeuvre, though never exceeding
the programmed speed.

The active cruise control operates byday and at night, in fog or in moderate rainfall.


The system does not act on the brakingsystem, but works only with engine braking.
The regulation range is limited: there willno longer be any adjustment of speed if the difference between the programmed speedsetting and the speed of the vehicle in front becomes too high (18 mph (30 km/h).


The activation of this system deactivates the function of inter-vehicle time.


If the difference between the programmed speed setting and the speed of the vehicle in front is toogreat, the speed cannot be adjusted: the cruise control is automatically
deactivated.

which will make the current speed of your vehicle the new cruise speed setting, rather than by pressing button 4(on/pause) which reactivates the cruise control using the old cruise speed setting, which may be very different from the current speed of your vehicle.

"
SPEED ADJUSTED" Detection of a vehicle that is too close or running at a speed lower than your
vehicle's cruise speed setting.
The system uses engine braking to slow your vehicle and then hold it at the speed of
the vehicle in front so as to maintain the programmed inter-vehicle time.
The regulation range is limited to a maximum difference of 20 mph (30 km/h)between the speed setting and the speed of the vehicle ahead.
"
Cruise control paused". If the system exceeds the limit of speed adjustment possible by the system and in
the absence of any reaction by the driver (operation of the direction indicator, change
of lane, reduction of the speed of the vehicle), the system is automatically paused.
The display of the deactivation message is accompanied by an audible signal.

180
Driving
The active cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle looses speed slowly, as when releasingthe accelerator pedal.
The system is paused automatically:
- if the vehicle in front slows down to much
or too suddenl
y, and the driver does notbrake,
- if a vehicle comes between your vehicle and the vehicle in front,
- if the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.
Limits of operation

As the radar's field of view is quite narrow, it is
possible that the system may not detect:
Th
e cruise control does not take account of:


- stationary vehicles,

- vehicles driving in the opposite direction.

- vehicles o
f reduced width, such as
motorcycles, for example,


- vehicles not runnin
g in the middle of the lane,


- ve
hicles entering a corner,


- vehicles changing lane at the last moment.
The re
gulation range is limited to a maximum
difference of 20 mph (30 km/h) between thespeed setting and the speed of the vehicle ahead. Above this, the system goes into pause
if a safe distance is not maintained.
Severe weather conditions (very heavy rain, accumulations of snow in frontof the radar) can interfere with theoperation of the system, resulting inthe display of the message "SYSTEMINACTIVE: Visibility reduced". Thefunction remains unavailable until themessage disappears.
