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.

Operation









Gear shift indicator

System which reduces fuel consumption by advising the driver to change up.
With an electronic gearbox, the system is only active in Manual mode.


The system adapts its gear change recommendation according to thedriving conditions (slope, load, ...) and the demands of the driver (power,acceleration, braking, ...).
The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.
Example:
- You are in third gear.
- Yo u press the accelerator pedal.
- The s
ystem may suggest that you engage a
higher gear.
The in
formation appears in the instrumentpanel in the form of an arrow. On vehicles with manual gearbox, the arrowcan be accompanied by the recommended gear.
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 instruction without engaging the
intermediate gears.
The gear engagement recommendations mustnot be considered compulsory. In fact, the configuration of the road, the amount of traffic
and safety remain determining factors whenchoosing 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.

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.

Safety








Ty r e u n d e r - i nfl ation detection
The system continuously monitors thepressures on the four tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever
y time the tyre pressures are adjusted or a wheel changed. The system triggers an aler t as soon as it
detects a drop in the inflation pressure of one
or more tyres.
The under-inflation detection system does not replace the vigilance or theresponsibility of the driver. This system does not avoid the need tocheck the tyre pressures (including the spare wheel) every month as well as before a long journey. Driving with under-inflated tyres impairsroad holding, extends braking distances and causes premature tyre wear,particularly under arduous condition(high loading, high speed, long journey). S
ystem which automatically checks the pressure of the tyres while driving.

The inflation pressures defined for your vehicle can be found on the tyrepressure label (see the "Identificationmarkings" section). Tyre pressures should be checkedwhen the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderatespeeds). Other wise, add 0.3 bar to the pressures shown on the label.

Driving with under-inflated tyresincreases fuel consumption.

Checks























Fuel
Capacity of the tank: approximately 57 litres (petrol) or 55 litres (Diesel).


Low fuel level
Refuelling
When the low fuel level is reached,
this warning lamp in the instrumentpanel comes on, accompanied by anaudible warning, a message and the
last bar of the fuel gauge comes on in orange.
) Take care to select the pump that delivers
the correct type of fuel for your vehicle.) Introduce the nozzle so as to push in themetal non-return flap A.)
Make sure that the nozzle is pushed in as
far as possible before star ting to refuel (risk
of blowback). ) Maintain this position throughout the
refuelling operation.) Push the fuel flap to close it.
If you are filling your tank to the top, do
not persist after the 3rd cut- off; this could cause malfunctions.
A label on the inside of the fuel filler flapreminds you of the type of fuel to use,
depending on your engine type.
Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge. When it
first comes on, about 6 litresof fuel
remain in the tank.
Until sufficient fuel has been added, this warninglamp appears every time the ignition is switched
on, accompanied by an audible warning and amessage. This audible warning and message
are repeated with increasing frequency as the fuel level drops towards "0".
Refuel as soon as possible to avoid running out.
Opening the filler flap may result in an inrush of air. This is entirely normal and results from the
sealing of the fuel system.
) Press the rear edge of the flap to open it
(the filler cap is par t of it).
With Stop & Star t, never refuel with the
system in STOP mode; you must switchoff the ignition with the START/STOP button.

314
Checks
The petrol or Diesel engine of your vehicle is fitted with a catalytic conver ter, a device which helps to reduce the level of harmful emissions
in the exhaust gases.
For petrol en
gines, you must use unleaded fuel.The filler neck is narrower, allowing only
unleaded petrol nozzles to be introduced.
If you have put in the wrong fuel for your vehicle, you must have thefuel tank drained and filled withthe correct fuel before star ting the engine.

Fuel cut- of f

Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of acollision.

Checks

















Misfuel prevention (Diesel) *


Operation

When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remainsclosed and prevents filling.Do not persist but introduce a Diesel type filler nozzle.

*
Depending on country of sale. Mechanical device which prevents fillin
g the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the
wrong fuel.
It remains possible to use a fuel can tofill the tank. In order to ensure a good flow of fuel,do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device and pour slowly.


Travelling abroad

As Diesel fuel pump nozzles may be different in other countries, thepresence of the misfuel prevention device may make refuelling impossible.
Before travelling abroad, werecommend that you check with the CITROËN dealer network, whether your vehicle is suitable for the fuel pumps inthe country in which you want to travel.
