Programming
Turn dial 1 to the "LIMIT" position: the
speed limiter mode is selected but is not
switched on (Pause).
You do not have to switch the speed limiter on
in order to set the speed.
Set the speed value by pressing button 2
or 3 (e.g.: 55 mph (90 km/h)).
You can then change the programmed speed using buttons 2 and 3 :
- by + or - 1 mph (km/h) = short press,
- in steps of + or - 5 mph (km/h) = maintained press.
If speed memorisation is available and activated on your vehicle, the
programmed speed will stop at the closest memorised speed; refer to the
corresponding paragraph.
Switch the speed limiter on by pressing button 4.
Switch the speed limiter off by pressing button 4: the display
confirms that it has been switched off (Pause).
Switch the speed limiter back on by pressing button 4 again.
Exceeding the programmed speed
Pressing the accelerator pedal to exceed the programmed speed will
not have any effect unless you press the pedal firmly past the point of
resistance .
The speed limiter is deactivated temporarily and the programmed speed,
which is still displayed, flashes.
Returning to the programmed speed, by means of intentional or
unintentional deceleration of the vehicle, automatically cancels the
flashing of the programmed speed.
Exiting the speed limiter
mode
Turn dial 1 to the "0" position: the speed
limiter mode is deselected. It disappears
from the screen.
Operating fault
In the event of a fault with the speed limiter,
the speed is cleared resulting in flashing of the
dashes.
Have it checked by a CITROËN dealer or a
qualified workshop.
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.
To avoid any risk of jamming of the
pedals:
- ensure that the mat is positioned
correctly,
- do not fit one mat on top of another.
