DRIVING
In the event of a steep descent or
under excessive acceleration, the
speed limiter (which does not act
on the brakes) may not be able to
prevent the vehicle from exceeding
the programmed speed.
Use of a fl oor mat other than that
recommended by CITROËN may
affect the normal operation of the
accelerator pedal and hamper the
operation of the speed limiter.
Floor mats approved by CITROËN
are fi tted with a 3rd fi xing located in
the pedal area to avoid any risk of
interference with the pedals.

Suspension/Resumption



)

.
This action causes the information
"PAUSE"
to appear in zone A

instrument panel.


Overriding the programmed
speed
The accelerator pedal has an end-
of-travel switch. In order to exceed
the memorised maximum speed at
any time, you can press the pedal
all the way down. While the speed
is being exceeded, the speed dis-
played in zone A
will fl ash. You have
only to release the accelerator pedal
to return below the maximum speed,
to restore the function.
The speed will also fl ash if the speed
limiter is not able to prevent the vehi-
cle from exceeding the programmed
speed (e.g. on a steep descent or
under excessive acceleration).
To reactivate the speed limiter, re-
lease the accelerator to slow to a
speed lower than the programmed
speed.
