Operating fault

When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd
gear. You may feel
a substantial knock when changing from Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed restrictions permitting.
Have it checked by a CITROËN dealer or aqualified workshop.
This warning lamp may also come on if a door
is opened.
You risk damaging the gearbox:


- if you press the accelerator and brake pedals at the same time,

- if you force the lever from position Pto another position when the batteryis flat.

To reduce fuel consumption when stationary for long periods with the engine running (traffic jam...), positionthe gear lever at Nand apply theparking brake, unless it is programmed in automatic mode.

g fault

If a fault occurs with the system, these warninglamps come on. Contact a CITROËN dealer or a qualified workshop to have the system
checked.


Do not leave the vehicle while it is being held in the hill star t assist phase.
If you need to leave the vehicle whilethe engine is running, apply the parking brake manually then ensure that theparking brake warning lamp is on (notflashing) in the instrument panel.On a descending slope, with the vehicle
stationar
y and reverse gear engaged, thevehicle is held for a brief moment when you

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 restar ts automatically - START mode - as soon as you want to move off. The restar t 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.
Operation
Going into engine STOP mode
With the electronic gearbox system, for your comfor t 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 asbraking, power steering, for example.
Never refuel with the engine in STOPmode; you must switch off the ignition with the key. Th
e "ECO"warning lamp comes on
in the instrument panel and the engine 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 clutchpedal,
- with the 6-speed electronic gearbox
system, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put thegear lever into position N.
If your vehicle is fitted with the system, a time counter calculates
the sum o
f the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key.
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 star t using the key,

- the electric parking brake is applied or
bein
g applied,

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

- demisting is active,

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


Special cases: STOP modeunavailable

In this case, the "ECO"warning lamp
flashes for a few seconds, then goes off.
This operation is per fectly normal.

operation, START mode is invoked
automatically 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 k m/h) with the 6 -speed electronic
gearbox system,
- the electric parkin
g brake is being applied,
- some special conditions (battery charge,engine temperature, braking assistance,
ambient temperature...
) where the engine is
needed to assure control of a system.

The system is reactivated automaticallyat every new star t using the key.
Reactivation

This system requires a specific battery with aspecial specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the system. In the event of a malfunction with the s
ystem,
the "ECO OFF"switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.


Operating fault

The alert is given by a warning lamp whichcomes on in the door mirror on the side inquestion as soon as a vehicle - car, lorry,cycle - is detected and the following conditions are fulfilled:


- all the vehicles must be moving in the same
direction,

- the speed of
your vehicle is between 7 and
75 mph (12 and 140 km/h),

- the difference in speed between your
vehicle and the other vehicles must be lessthan 6 mph (10 km/h),

- the traffic must be flowing normally,

- in the case of an over taking manoeuvre,
if this is prolonged and the vehicle beingover taken remains in the blind spot,

-
you are driving on a straight or slightly curved road,

- your vehicle is not pulling a trailer, a caravan...

- when overtakin
g (or being over taken by) a
very long vehicle (lorry, coach...) which is at the same time detected at the rear in theblind spot angle and present in the driver's
for ward field of vision,

- in ver
y heavy traffic: vehicles detected in
front and behind are confused with a lorryor a stationary object,

- when overtaking quickly.
