Display of inter-vehicle time
Using a radar located at the front of the vehicle, this system helps the driver maintain a safe
d
istance between their vehicle and the one in
f
ront, by displaying the current inter-vehicle
t
ime in the instrument panel.
It
is the time interval, expressed in seconds,
t
hat separates two vehicles in line. The
r
ecommended safe value is about 2 seconds:
r
efer to the legislation or highway code in force
i
n your country.Conditions for display
The measurement is displayed for information only: the system takes no a
ction on the vehicle.
This
system does not in any
c
ircumstances replace the need for
v
igilance on the part of the driver who
m
ust remain in control of the vehicle at
a
ll times.
The
system is not designed for urban
u
se
nor
for
more
dynamic
driving
(bends,
a
cceleration, harsh braking…) but rather
w
hen driving at a steady speed.
The
system is active in a speed range
b
etween 42 and 93 mph (70 and
1
50 km/h).
Stationary vehicles and certain other
r
oad users (such as bicycles for
e
xample) are not detected.
The system displays inter-vehicle time
v
alues of between 3 seconds and 0.5 of
a
second.
Below 0.5 of a second, the value
d
isplayed is maintained at this level,
e
ven if the true inter-vehicle time is less.
The active cruise control must not
b
e selected (the active cruise control
i
nformation is displayed instead of that
f
or the inter-vehicle time).
The system is only available with the
"
DRIVING" display mode of the
type 2 instrument panel.

Cruise control "CRUISE"
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance on the part of the driver.
Y ou are advised to keep your feet near the pedals at all times.
Switching on the cruise control requires a
minimum vehicle speed of 25 mph (40 km/h).

active cruise control
This systems allows, in addition to maintaining your vehicle's speed at a value that you have defined, the inter-vehicle time you have selected between your vehicle and the one ahead to be
m
aintained.Principles of operation
Using a radar with a range of about 100 metres, located at the front of the vehicle, this system
d
etects a vehicle running in front of your
v
ehicle.
It
automatically adapts the speed of the vehicle
t
o that of the vehicle in front.
If
the vehicle in front is running more slowly,
t
he system progressively reduces the speed of
y
our vehicle using just engine braking (as if the
d
river had pressed the "-"
button).
If
your vehicle is too close to or approaching
t
oo quickly the vehicle in front, the cruise
c
ontrol is automatically deactivated. The
d
river is then alerted by an audible signal,
a
ccompanied by a message.
If
the vehicle in front accelerates or changes
l
ane, the active cruise control progressively
a
ccelerates your vehicle to return to the
programmed
s
peed.
If
the driver operates a direction indicator to
t
he left (left hand drive) or the right (right hand
d
rive), to overtake a slower vehicle, the active
c
ruise control allows your vehicle to temporarily
a
pproach the vehicle in front to assist the
overtaking

noeuvre,

s
afety reasons,
-
i
