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.
The cruise control is switched off manually, by
an action on the brake or clutch pedal or if the
ASC system is triggered.
The programmed 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 of this system are grouped
together on the steering wheel.

Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-
a
nti-lock braking system (ABS),
-

e
lectronic 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 particular on poor or slippery sur faces.
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 stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system 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 as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds 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

143
When the vehicle is moving
If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock braking
system 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 are
displayed alternately in the instrument
panel screen.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible.
If these two warning lamps come on, linked
with the warnings on the instrument panel
screen, they 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 qualified
workshop.

Fitting a wheel
After changing a wheel
When using the "space-saver" spare
wheel, do not exceed a speed of
50 mph (80 km/h).
Have the tightening of the bolts and the
pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.
Have the punctured wheel repaired and
replace it on the vehicle as soon as
possible.
List of operations

Fitting snow tyres
If you equip your vehicle with snow
tyres fitted on steel wheel rims, special
bolts available from your CITROËN
dealer or a qualified workshop must
be used.
If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.
