Braking assistance systems
Group of supplementary systems which helpyou to obtain optimum braking in complete safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution
(EBFD),
- emergency braking assistance (EBA).

Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in par ticular on poor or slippery surfaces.
Activation
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.
When braking in an emergency, pressvery firmly without releasing thepressure.


Operating fault
If this warning lamp comes on,
together with the STOPand ABSwarning lamps, accompanied by an
audible signal and a message in the screen, it
indicates a malfunction of the electronic brake force distribution which could result in loss of control of the vehicle when braking.You must stop as soon as it is safe to do so.

When replacing wheels (tyres andrims), ensure that they conform to themanufacturer's recommendations.
If this warnin
g lamp comes on,
accompanied by an audible signaland a message in the screen, it
indicates a malfunction of the anti-lock brakingsystem which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.

Invalid value during manualoperation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).

Stopping the vehicle
Before switching off the engine, you canengage position Por N
to place the gearbox in neutral.
In both cases, apply the parking brake toimmobilise the vehicle, unless it is programmedto automatic mode.

If the lever is not in position P, when thePdriver's door is opened or approximately45 seconds after the ignition is switched off, there is an audible signal and amessage appears.)Return the lever to position P
; the audible signal stops and themessage disappears.


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.

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.

The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.

Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the axle and the nose weight approaches the maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing engine per formance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towed load on a long inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.

Braking

To w i ng a trailer increases the braking distance.
To a v o i d o v e r h e a t i ng of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.


Tyres
)Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the electrical lighting and signalling on the trailer.
)If the warning lamp and the
STOP warning lamp come on, stop the vehicle and switch off
t
he engine as soon as possible.
