CRUISE CONTROL "CRUISE"
On vehicles fi tted with an automatic
gearbox, the lever must be in
position D (Drive) or at least 2nd gear
must be engaged in manual mode. Function selected,
displaying of the
"Cruise Control"
symbol.
Function deactivated,
OFF (example at
65 mph (107 km/h)).
Function activated
(example at 65 mph
(107 km/h)).
Vehicle speed above
(e.g. 70 mph
(118 km/h)),
the programmed
speed is displayed
fl ashing.
Operating fault
detected,
OFF - the dashes
fl ash.
This cruise control shows the function
selection status on the instrument
panel and displays the programmed
speed:
"This is the speed at which the driver
wishes to drive".
This aid to driving in free-fl owing
traffi c enables the vehicle to maintain
the speed programmed by the driver,
unless a steep gradient makes this
impossible.
In order for it to be programmed or
activated, the vehicle speed must be
greater than 25 mph (40 km/h) with at
least 4th gear engaged in the case of
vehicles fi tted with a manual gearbox. If the vehicle is fi tted with a speed
limiter and cruise control (according
to the country in which the vehicle is
sold and the engine), these functions
cannot be activated at the same time.

selected but is not yet active and
no speed has been programmed.
First activation/
programming a
speed
- Reach the chosen speed by pressing the
accelerator.
- Press the SET - or

SET + button .
This programmes/activates the
reference speed and the vehicle will
maintain this speed. Temporary exceeding of the
speed
It is possible
to accelerate and drive
momentarily at a speed greater than
the programmed speed. The value
programmed fl ashes.
When the accelerator pedal is
released, the vehicle will return to the
programmed speed. Reactivation
- Following deactivation of the cruise
control, press this button.
Your vehicle will return to the last

Switching the function off
- Place the dial in position 0 or switch
off the ignition to switch everything off. Good practice
When changing the programmed
reference speed by means of a
maintained press, pay attention as
the speed can increase or decrease
rapidly.
Do not use the cruise control on
slippery roads or in heavy traffi c.
In the event of a steep slope, the cruise
control cannot prevent the vehicle from
exceeding the programmed speed.
In any event, the cruise control cannot
replace the need to observe the speed
limits, nor can it replace the need for
vigilance and responsibility on the part
of the driver.
You are advised to keep your feet near
the pedals.
To avoid any jamming under the
pedals:
- ensure that the mat and its fi xings on the fl oor are positioned correctly,
- never place one mat on top of another
Changing the
programmed speed
There are two methods
of memorising a
speed higher than the
previous one:
Without using the accelerator:
- press the Set + button.
A brief press increases the speed by
1 mph (km/h).
A maintained press increases the
speed in steps of 5 mph (km/h).
Operating fault
The programmed speed is cleared and
the dashes fl ash for a few seconds.
Consult a CITROËN dealer to have the
system checked.
Using the accelerator:
- exceed the memorised speed until
the speed required is reached,
- press the Set + or Set - button.
To memorise a speed lower than the
previous one:
- press the Set - button.
A brief press decreases the speed by
1 mph (km/h).
A maintained press decreases the
speed in steps of 5 mph (km/h). Cancelling the programmed
reference speed
When the vehicle becomes stationary,
after switching off the ignition, the
system no longer memorises a speed.

SPEED LIMITER "LIMIT"
To resume use of the limiter,
simply reduce the pressure on the
accelerator pedal gradually and return
to a speed below that programmed.
If the vehicle is fi tted with a speed
limiter and cruise control (according
to the country in which the vehicle is
sold and the engine), these functions
cannot be activated at the same time .

The operating actions can be carried
out when stationary, with the engine
running, or with the vehicle moving. Function selected,
displaying of the
"Speed Limiter"
symbol.
Function deactivated,
last programmed
speed - OFF
(example at 65 mph
(107 km/h)).
Function activated
(example at 65 mph
(107 km/h)).
Vehicle speed above
(example at 70 mph
(118 km/h)), the
programmed speed is
displayed fl ashing.
Operating fault
detected, OFF -
the dashes fl ash.
This speed limiter shows the function
selection status on the instrument
panel and displays the programmed
speed:
"This is the selected speed which the
driver does not wish to exceed".
This selection is made with the engine
running while stationary or with the
vehicle moving. The minimum speed
which can be programmed is 20 mph
(30 km/h).
The speed of the vehicle responds
to the pressure of the driver’s foot as
far as the accelerator pedal point of
resistance which indicates that the
programmed speed has been reached.
However, pressing the pedal beyond
this point of resistance to the fl oor
permits exceeding of the
programmed speed.

Selecting the function
- Place the dial in the LIMIT position.
The limiter is selected but is not yet
active. The display indicates the
last programmed speed.
Programming a speed
A speed can be programmed without
activating the limiter but with the
engine running.
To memorise a speed higher than the
previous one:
- press the Set + button.
A brief press increases the speed by
1 mph (km/h).
A maintained press increases the
speed in steps of 5 mph (km/h). Activation/Deactivation (off)
Pressing this button once activates
the limiter, pressing the button again
deactivates it (OFF).
To memorise a speed lower than the
previous one:
- press the Set - button.
A brief press decreases the speed by
1 mph (km/h).
A maintained press decreases the
