Cruise control
System which automatically maintains the vehicle speed at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control is switched on
manually:
the vehicle speed must be at least 25 mph(40 km/h) and second gear or higher must be engaged in the case of a manual gearbox.
Th
e cruise control is switched offmanually, byfan action on the brake or clutch pedal or if theASC system is triggered.
The pro
grammed speed can be exceeded
temporarily by pressing the accelerator pedal.
The cruise control cannot, in any circumstances, take the place of the need to comply with speed limits or of the vigilance and responsibility of the driver. The controls o
f this system are grouped
together on the steering wheel.1."ON/OFF"
button: activation / deactivation of the cruise control mode.
2
."COAST SET"button: store a drivingspeed and decrease the cruising speed. 3."ACC RES"
button: increase the cruising speed and recall the stored speed.4."CANCEL"button: stop control of the
vehicle's speed.

Steering mounted controls
When you press button 1, the "CRUISE"indicator comes on in the instrument panel.

Te m p o r a ry acceleration

Press the accelerator pedal as normal. When
the pedal is released, you return to the stored speed.
) Using button 2 "COAST SET":- successive presses decrease the speed in steps of approximately 1 mph (1.6 km/h).
- a maintained press of this button
decreases the speed pro
gressively. Once the speed required has been reached,release the button, the new speed is stored.)
Using the brake pedal:
- brake to deactivate the cruise control, then press button 2 "COAST SET"
. Release to store the new speed.

)Using button 3 "ACC R ES":


- successive presses increase the speed insteps of approximately 1 mph (1.6 km/h).

- a maintained press of this button increases
the pro
grammed speed progressively.
Once the speed required has been reached,
release the button, the new speed is stored.
)Using the accelerator pedal:


- accelerate to reach the speed required,
then press button 2 "COAST SET".Release the button to store the new speed.


Temporary deceleration
Press the brake pedal to reduce the speed. To
return to the stored speed, press button 3 "ACC
RES".

Driving
When the cruise control is in operation,pay attention if you press and hold oneof the programmed speed adjustment buttons: this can result in a very rapidchange in the speed of your vehicle.
Do not use the cruise control on slippery roads or in heavy traffic. On a steep descent, the cruise control will not be able to prevent the vehiclefrom exceeding the programmed speed.
To prevent the mat from becomingcaught under the pedals:


- ensure that the mat is positioned correctly,


- never fit one mat on top of another.
T
o deactivate the cruise control:
)press the brakeor clutchpedal, or )press button 1 "ON OFF", or )press button 4 "CANCEL".
Deactivating the function
Reactivating the function

When the cruise control has been deactivatedusing the button 4 "CANCEL"
, you can return
to the stored speed by pressing button 3 "ACC
RES"
when you reach a minimum speed of 25 mph (40 km/h).

The cruise control may be deactivatedautomatically:
)when the vehicle reaches a speed below
20 mph (35 km/h),)when the active stability control system (ASC) comes into operation.

Safety
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).























Braking assistance systems


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 is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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.


Operating fault

When the vehicle is stationar
y

If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock brakin
gsystem which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop assoon as possible.
When braking in an emergency, pressvery firmly without releasing thepressure.

The warning lamp comes on for a fewseconds when the ignition is switched on (ON position). If it does not switch off or does not come on, contact a CITROËN dealer or a qualified workshop.

Safety
When the vehicle is moving
If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock brakingsystem which could result in a loss of control of the vehicle on braking.
The two warning lamps comes on at the same time and the two warnings aredisplayed alternately in the instrumentpanel screen. When replacing wheels (tyres and rims), ensure that they conform to themanufacturer's recommendations.

The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible. I
f these two warning lamps come on, linked with
the warnings on the instrument panel screen,
the
y indicate a malfunction of the electronic brake force distribution which could result in a loss of control of the vehicle on braking.
You must stop as soon as it is safe to do so.Contact a CITROËN dealer or a qualifiedworkshop.

Safety
Associated systems which guarantee the directional stability of the vehicle within the limits of the laws of physics:
- traction control (TCL),
- active stability control (ASC).

Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.

Activation

These systems are activated automaticallyeach time the vehicle is started.
The illumination o
f this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are deactivated.


Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can movefreely and regain grip.
This is indicated b
y flashing of this symbol on the instrument panel screen.






















Trajectory control systems
)Press this button, located to the left of thesteering wheel, until the symbol appears in
the instrument panel screen.

Operation

They operate when the vehicle speed is higher
than 10 mph (15 km / h).
They come into operation in the event of a grip
or trajectory problem.
