ress or the " +" or " -" button to choose
a new inter-vehicle time setting between
2.5


seconds and 1 second. In the event of the presence of a
vehicle detected by the radar, if the
speed selected is much higher than
the speed of that vehicle, the system
is not activated and the alert message
"Activation not possible, conditions
unsuitable" is displayed until driving
conditions are safe to allow activation of
the system.
Exceeding the programmed
speed
It is possible to exceed the programmed speed
temporarily by depressing the accelerator
pedal.
Simply release the accelerator pedal to return
to the programmed speed.
If the programmed setting is unintentionally
exceeded, descending a steep hill for example,
the speed setting in the instrument panel
flashes as a warning.Button 5 (MEM)
this setting remains memorised, whatever the
state of the system.
th

e selection screen closes after a few
moments.
t

"Detection of a vehicle that is too close or running at a speed lower than your

th

e system uses engine braking to slow your vehicle (within a limit of 20 mph
(30
km/h)) and then hold it at the speed of the vehicle in front so as to observe the
programmed inter-vehicle time.
When automatically slowing down behind a vehicle, your true speed may be higher

the absence of any reaction by the driver (operation of the direction indicator, change

When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. t
h
e message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the function be
reactivated by pressing button 2 (S
et
+
)
or 3 (S
e

t
-
), which will make the current
speed of your vehicle the new cruise
speed setting, rather than by pressing
button 4 (on/pause) which reactivates
the cruise control using the old cruise
speed setting, which may be very
different from the current speed of your
vehicle.th e speed regulation range is limited to a
maximum difference of 20 mph (30 km/h)
between the speed setting and the speed of the
vehicle in front.
Above this, the system goes into pause if the
safe distance becomes too low.
th

e dynamic cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
th

e system is paused automatically:
-

i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and the vehicle in front,
-

i
f the system does not slow the vehicle
enough to continue to maintain a safe
distance, for example when descending a
steep hill.
Limits of operation
As the radar's field of view is quite narrow, it is
possible that the system may not detect:th e cruise control does not take
account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite
direction.
-

v
ehicles of reduced width, such as
motorcycles, -

v

lane,

In the event of a fault with the dynamic cruise
control, you are alerted by an audible signal
and display of the message message "Driving
aid functions fault".
Have the system checked by a P
e
uge
Ot

dealer or a qualified workshop. When the cruise control is working, take
care if making a maintained press on
one of the cruise control programmed
speed modification buttons: this can
lead to a very quick change in the
speed of your vehicle.
Do not use the dynamic cruise control
on slippery sur faces or in heavy traffic.
When descending a steep hill, the
cruise control may not be able to
prevent the vehicle from exceeding the
programmed speed.
When ascending a steep hill or when
towing, it might not be possible to attain
or maintain the programmed speed.
Operating fault
the operation of the radar, located in
the front bumper, may be disturbed in
certain weather conditions, for example:
with accumulations of snow, ice,
mud,

Display of inter-vehicle time
using a radar located at the front of the vehicle,
this system helps the driver maintain a safe
distance between their vehicle and the one in
front, by displaying the current inter-vehicle
time in the instrument panel.
th
is is the time interval, expressed in seconds,
that separates two vehicles in line.
th

e recommended safe value is about
2


seconds.
Refer to the legislation or highway code in force
in your country.Activation / deactivation*
F Press this button, the indicator lamp comes on.
th

e measurement is displayed for
information only: the system takes no
action on the vehicle.
th

is system does not in any
circumstances replace the need for
vigilance on the part of the driver, who
must remain in control of the vehicle at
all times.
th

e system is not designed for urban
use nor for more dynamic driving
(bends, acceleration, harsh braking…)
but rather when driving at a steady
speed.
th

e system is active in a speed range
between 42 and 93 mph (70 and
150


km/h).
Stationary vehicles and certain other
road users (such as bicycles for
example) are not detected.
th

e system displays inter-vehicle time
values of between 3 seconds and 0.5 of
a second.
Below 0.5 of a second, the value
displayed is maintained at this level,
even if the true inter-vehicle time is less.
th

e state of the system is memorised when the
ignition is switched off. Activation of the system is done in the " Driving
assistance " menu, with the engine running.
* Depending on version.
Conditions for display
the dynamic cruise control must not
be selected (the dynamic cruise control
information is displayed instead of that for the
inter-vehicle time).
