Hill start assist

On an ascending slope, with the vehicle
stationary, the vehicle is held for a brief
moment when you release the brake pedal:
- if you are in first gear or neutral with a

manual gearbox,

-

if you are in position D or M with an
automatic gearbox.

Operation

On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a brief moment when you
release the brake pedal.

Operating fault

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

System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.

This function is only active when:
- the vehicle is completely stationary, with

your foot on the brake pedal,

- when certain conditions of gradient are

met,

- with the driver’s door closed.
The hill start assist function cannot be
deactivated.

Do not leave the vehicle while it is being
held in the hill start assist phase.
If you need to leave the vehicle while
the engine is running, apply the parking
brake manually then ensure that the
parking brake warning lamp is on (not
flashing) in the instrument panel.

Tyre under-inflation 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
each tyre (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 vigilance on the part of the driver.

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).

The tyre pressures for your vehicle can
be found on the tyre pressure label.
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).
Otherwise, add 0.3 bar to the values
indicated on the label.
For more information on identification
markings, including the tyre pressure
label, refer to the corresponding
section.

Driving with under-inflated tyres
increases fuel consumption.

C4-2_en_Chap06_conduite_ed02-2015

The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by the
illumination of the service warning
lamp indicates a fault with the system.

Operating fault

The alert is given by the fixed
illumination of this warning lamp,
accompanied by an audible signal,
and depending on equipment, the
display of a message.

Under-inflation alert

In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.

F

Reduce speed, avoid sudden steering

movements or harsh brake applications.

F

Stop as soon as it is safe to do so.

In this case, monitoring of the tyre pressures is
not assured.

F

If you have a compressor (the one in the

temporary puncture repair kit for example),
check the four tyre pressures when cold.

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

or
F In the event of a puncture, use the

temporary puncture repair kit or the spare
wheel (according to equipment).

Go to a CITROËN dealer or a qualified
workshop to have the system checked or,
following the repair of a puncture, to have the
original wheel, equipped with a sensor, refitted.
Any tyre repair or replacement on a wheel
fitted with this system must be carried out by a
CITROËN dealer or a qualified workshop.
If after changing a tyre, a wheel is not detected
by your vehicle (fitting snow tyres for example),
you must have the system reinitialised by a
CITROËN dealer or a qualified workshop.

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
(for example, a space-saver or steel
spare wheel).

The alert is maintained until the tyre or
tyres concerned is reinflated, repaired
or replaced.
The spare wheel (space-saver type or a
steel rim) does not have a sensor.

Lane departure warning system

Activation

Deactivation

Detection

Operating fault

System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motorways
and main roads.

In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message in the screen.

Contact a CITROËN dealer or a qualified
workshop.

The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of the
driver.
It is necessary to observe driving
regulations and take a break every
two hours.

The detection may be impeded:
- if the sensors are dirty (mud, snow...),
- if the markings on the ground are

worn,

-

if there is little contrast between the
markings on the ground and the
road surface.

You are warned by the vibration of the driver's
seat cushion:
- on the right-hand side, if the marking on

the ground has been crossed on the right,

- on the left-hand side, if the marking on the

ground has been crossed on the left.

No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is
switched off.
A warning may be transmitted if a direction
marking (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.

F

When switching the ignition on or with

the engine running, press this button; the
indicator lamp comes on.

F

Press this button again, the indicator lamp

goes off.

The status of the system remains in the
memory when the ignition is switched off.

Blind spot sensors

This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this
presents a potential danger.

Operation

F

On switching on the ignition, or engine

running, press this button to activate the
function; the warning lamp comes on.

Sensors fitted in the front and rear bumpers
monitor the blind spots.

A warning lamp appears in the door mirror on
the side in question:
- immediately, when being overtaken,
-

after a delay of about one second, when
overtaking a vehicle slowly.

This system is designed to improve
safety when driving and is in no
circumstances a substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess
the distances and relative speeds
of other vehicles and to predict their
movements before deciding whether to
change lane.
The blind spot sensor system can never
replace the need for vigilance on the
part of the driver.

Driving

196

C4-2_en_Chap06_conduite_ed02-2015

No alert will be given in the following situations:
- in the presence of immobile objects

(parked vehicles, barriers, street lamps,
road signs...),

- with vehicles moving in the opposite

direction,

- driving on a sinuous road or a sharp

corner,

The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle - car, lorry,
cycle - is detected.
For this, the following conditions must be met:
- 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),

- when you overtake a vehicle with a speed

difference of less than 6 mph (10 km/h),

- when a vehicle overtakes you with a speed

difference of less than 15 mph (25 km/h),

- the traffic must be flowing normally,
- in the case of an overtaking manoeuvre,

if this is prolonged and the vehicle being
overtaken 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 overtaking (or being overtaken by) a

very long vehicle (lorry, coach...) which is
at the same time detected at the rear in the
blind spot angle and present in the driver's
forward field of vision,

- in very heavy traffic: vehicles detected in

front and behind are confused with a lorry
or a stationary object,

- when overtaking quickly.

F

To deactivate the system, press this button

again; the warning lamp goes off.

The state of the system remains in memory on
switching off the ignition.

Operating fault

The system is automatically deactivated
when towing with a towbar approved by
CITROËN.

The system may suffer temporary
interference in certain weather
conditions (rain, hail...).
In particular, driving on a wet surface
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud, ice
or snow.
Take care not to cover the warning zone
in the door mirrors or the detection
zones on the front and rear bumpers
with adhesive labels or other objects;
they may hamper the correct operation
of the system.

In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.

Temporarily exceeding the
programmed speed

When descending a steep hill, the
cruise control system cannot prevent
the vehicle from exceeding the
programmed speed.

When required (overtaking manoeuvre...), it is
possible to exceed the programmed speed by
pressing the accelerator pedal.
The cruise control is temporarily overridden
and the programmed speed setting flashes.

Only use the cruise control if the traffic
conditions will allow you to drive for a
certain time at a steady speed and at a
safe distance from the vehicle ahead.
Do not activate the cruise control in
urban areas, in heavy traffic, on winding
or steep roads, on slippery or flooded
roads, or in conditions of poor visibility
(heavy rain, fog, falling snow...).
In some circumstances, it may not
be possible to maintain or reach the
programmed speed: towing, vehicle
heavily loaded, steep climb.

The use of mats not approved by
CITROËN may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the
pedals:
- ensure that the mat is positioned

correctly,

- never fit one mat on top of another.

To return to the programmed speed, simply
release the accelerator pedal.
Once the vehicle has returned to the
programmed speed, the cruise control takes
over again: the display of the programmed
speed setting becomes steady again.

You may have to brake to control the speed of
your vehicle. In this case, the cruise control is
automatically paused.
To activate the system again, press button 4.

Parking sensors

The system is switched on by engaging reverse
gear.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.

Rear parking sensors

Audible assistance

The proximity information is given by an
intermittent audible signal, the frequency of which
increases as the vehicle approaches the obstacle.
The sound emitted by the speaker (right or left)
indicates the side on which the obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.

Visual assistance

This supplements the audible signal by
displaying bars in the screen which move
progressively nearer to the vehicle.
When the obstacle is very close, the "Danger"
symbol is displayed in the screen.

This system cannot in any circumstances replace
the need for vigilance on the part of the driver.

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
which comes within the field of detection of
sensors located in the bumper.
Certain types of obstacle (stake, roadworks
cone, etc.) detected initially will no longer be
detected at the end of the manoeuvre, if they
are located in blind spots in the sensors' field
of detection.
