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.Driving with under-inflated tyres
increases fuel consumption.The tyre pressures for your vehicle can
be found on the tyre pressure label.
The tyre pressures must be checked
when the tyres are 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.
For more information on Identification
markings
, including the tyre pressure
label, refer to the corresponding
section.
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 under-inflation detection system is an
aid to driving which does not replace the need
for vigilance on the part of the driver. Pressure sensors are 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.

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
(e.g. 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.
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.
In the event of a problem on one of the tyres,
the symbol or the message appears, depending
on equipment, to identify it.

Operating fault
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.
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.

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
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 (e.g. fitting snow tyres),
you must have the system reinitialised by a
CITROËN dealer or a qualified workshop. In this case, monitoring of the tyre pressures is
not assured.

On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the programmed speed.The use of mats not approved by
CITROËN may inter fere with the
operation of the speed limiter.
To avoid any risk of jamming of the
pedals:
-

e
nsure that the mat is positioned
c o r r e c t l y,
-

d
o not fit one mat on top of another.
Temporarily exceeding the programmed speed
F If you want to temporarily exceed the programmed limit speed, press firmly on
the accelerator pedal, going beyond the
point of resistance . When the limit speed is exceeded but is not
due to action by the driver, there is an audible
signal to complete the alert.
Switching off
F Turn wheel 1 to the "0"
position: the
display of information on the speed limiter
disappears.
Operating fault
Flashing dashes indicate a fault with the speed
limiter.
Have it checked by a CITROËN dealer or a
qualified workshop.
The speed limiter is deactivated temporarily
and the displayed programmed speed flashes. Once the speed of the vehicle returns to
the programmed setting, the speed limiter
functions again: the display of the programmed
speed setting becomes steady again.

System which automatically maintains the cruising speed of the vehicle at a setting programmed by the driver, without any action on the accelerator
pedal. The cruise control is switched on
manually.
It requires a minimum vehicle speed of
25 mph (40 km/h) as well as:
-

engagement of fourth gear or
higher,
-

As a safety measure, you are advised
to keep your feet near the pedals at all
times.

programmed speed setting.
The cruise control system is a driving aid
that cannot, in any circumstances, replace

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.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.
Temporarily exceeding the
programmed speed
When required (overtaking manoeuvre...), it is
possible to exceed the programmed speed by
pressing the accelerator pedal.
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.
When descending a steep hill, the
cruise control system cannot prevent
the vehicle from exceeding the
programmed speed.
Switching off
F Turn wheel 1 to the "0" position: the cruise
control information disappears from the
screen.
Operating fault
Flashing dashes indicate a fault with the cruise
control system.
Have it checked by a CITROËN dealer or a
qualified workshop. The use of mats not approved by
CITROËN may inter fere with the
operation of the cruise control.
To avoid any risk of jamming of the
pedals:
-

ever fit one mat on top of another.
The cruise control is temporarily overridden
and the programmed speed setting flashes.
