Under-infl ation detection

This system continuously monitors the tyre
pressures and alerts you in the event of under-
inflation.

214




Blind spot sensors

In certain conditions, this system
detects the presence of a vehicle in
the blind spot. It informs you by means
of a warning lamp in the corresponding
door mirror.

Exterior customising
stickers
When cleaning your car with a high
pressure jet wash, keep the end of the
lance at least 30 cm away from the
stickers.

As a passenger, if you avoid connecting
your multimedia devices (film, music, video
game...), you will contribute towards limiting
the consumption of electrical energy, and so
of fuel.
Disconnect your portable devices before
leaving the vehicle.



Limit the causes of excess
consumption

Spread loads throughout the vehicle; place the
heaviest items in the bottom of the boot, as
close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.

At the end of winter, remove snow tyres and
refit your summer tyres.



Observe the recommendations
on maintenance

Check the tyre pressures regularly, when
cold, referring to the label in the door
aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on
any trailer or caravan.

Have your vehicle ser viced regularly (engine
oil, oil filter, air filter...) and obser ve the
schedule of operations recommended by the
manufacturer.



When refuelling, do not continue after
the third cut-off of the nozzle to avoid any
over flow.
Switch off the headlamps and front foglamps
when the level of light does not require their
use.

Avoid running the engine before moving off,
particularly in winter; your vehicle will warm
up much faster while driving.

At the wheel of your new vehicle, it is only after
the first 1 800 miles (3 000 kilometres) that you
will see the fuel consumption settle down to a
consistent average.

Braking assistance systems

Group of supplementary systems which help
you 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 particular on poor or slippery sur faces.

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, press
very firmly without releasing the
pressure.


Operating fault

If this warning lamp comes on,
together with the STOP
and ABS

warning 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 and
rims), ensure that they conform to the
manufacturer's recommendations.
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, it
indicates a malfunction of the anti-lock braking
system which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.

179Safety









Emergency braking assistance

System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake
pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press
firmly without releasing the pressure.



















Trajectory control systems (ESP)


Anti-slip regulation (ASR)
and electronic stability
control (ESC)

The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control acts on the brake
of one or more wheels and on the engine to
keep the vehicle on the trajectory required by
the driver, within the limits of the laws of physics.


Activation

These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on
snow: intelligent traction control.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control
limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
In extremely severe conditions (deep snow,
mud, ...), when it proves impossible to move off,
it may be useful to temporarily deactivate the
ESP/ASR systems to allow the wheels to spin
freely and so allow movement of the vehicle.

Ty r e u n d e r - i nfl ation detection


System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of a
each tyres (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.
The tyre under-inflation detection system is
an aid to driving which does not replace the
need for the driver to be vigilant or to drive
responsibly.
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressures for your vehicle
can be found on the tyre pressure
label (see the "Identification markings"
section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.

This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).

215Driving

Under-inflation alert


The loss of pressure detected does
not always lead to visible deformation
of the tyre. Do not rely on just a visual
check.

This alert is also displayed when one or
more wheels is not fitted with a sensor.

The alert is maintained until the tyre
or tyres concerned is reinflated or
repaired.

The aler t is given by the fixed illumination
of this warning lamp, accompanied by
an audible signal, and depending on
equipment, the display of a message.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.


Reduce speed, avoid sudden steering
movements or harsh brake applications.


Stop as soon as it is safe to do so.


In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment),
or


if you have a compressor, the one in the
temporary puncture repair kit for example,
check the four tyre pressures when cold,
or


if it is not possible to check the tyre
pressures at the time, drive carefully at
reduced speed.


Operating fault

The flashing and then fixed illumination
of the under-inflation warning lamp
accompanied by the illumination of the
"ser vice" warning lamp indicates a fault
with the system.
In this case, monitoring of the tyre pressures is
not assured.
Have the system checked by a CITROËN
dealer or a qualified workshop.

Temporary puncture repair kit


Complete system consisting of a compressor
and a sealant cartridge which permits
temporary repair
of a tyre so that you can
drive to the nearest garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.




Access to the kit


The speed limit sticker I
must be affixed
to the vehicle's steering wheel to
remind you that a wheel is in temporary
use.
Do not exceed a speed of 50 mph
(80 km/h) when driving with a tyre
repaired using this type of kit.



Description of the kit



A.
"Sealant" or "Air" position selector.

B.
On "I"
/ off "O"
switch.

C.
Deflation button.

D.
Pressure gauge (in bar and p.s.i.).

E.
Compar tment housing:


- a cable with adaptor for 12 V socket,

- various inflation adaptors for
accessories, such as balls, bicycle
tyres...
F.
Sealant cartridge.

G.
White pipe with cap for repair.

H.
Black pipe for inflation.

I.
Speed limit sticker.
This kit is installed in the storage box, under the
boot floor.


Switch on the compressor by moving
the switch B
to position "I"
until the tyre
pressure reaches 2.0 bars.
The sealant is injected into the tyre under
pressure; do not disconnect the pipe from
the valve during this operation (risk of
splashing).




Remove the kit and screw the cap back on
the white pipe.
Take care to avoid staining your vehicle
with traces of fluid. Keep the kit to hand.


Drive immediately for approximately three
miles (five kilometres), at reduced speed
(between 15 and 35 mph (20 and
60 km/h)), to plug the puncture.


Stop to check the repair and the tyre
pressure using the kit.

Do not start the compressor before
connecting the white pipe to the tyre
valve: the sealant product would be
expelled through the pipe.



Ty r e u n d e r - i nfl ation detection

If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the
system is reinitialised by a CITROËN
dealer or a qualified workshop.


If after around 5 to 7 minutes the
pressure is not attained, this indicates
that the tyre is not repairable; contact
a CITROËN dealer or a qualified
workshop for assistance.
