INTRODUCTION (1/4)
The Motorway and Traffic Assistant is a
driving aid system designed for use on
long motorway journeys, where traffic is
flowing or in jams.
This system comprises the Stop and
Go adaptive cruise control function
and the Lane Centring function.
When these two functions are activated
simultaneously, the system allows the
driver to:
– maintain vehicle speed based on a
previously saved speed;
– adjust the distance between this ve-
hicle and the vehicle in front;
– direct the vehicle to the centre of the
lane.
The Stop and Go adaptive
cruise control function.
Based on information from a radar or
camera, the Stop and Go adaptive
cruise control function gives you the
option of maintaining a selected speed,
known as the cruising speed, while
keeping a safe distance from the vehi-
cle in front in the same lane.
If the vehicle in front stops, the Stop
and Go adaptive cruise control may
brake your vehicle to a complete stop
before setting off again.
The system controls acceleration and
deceleration of your vehicle using the
engine and braking system.
The Stop and Go adaptive cruise con-
trol function can be activated from 0 to
105 mph (0 to 170 km/h) according to
conditions on the road (traffic, weather
etc.).
It is represented by the following symbol
 ➥ 10 .
Important: you should keep
your feet near the pedals
and your hands on the
steering wheel at all times
to prepare for any event.
Note:
– the driver must observe the maxi-
mum speed limit and safe distances
in the country where they are driving;
– the adaptive cruise control can brake
the vehicle up to a third of the brak-
ing capacity. Depending on the situ-
ation, the driver may need to brake
harder.
The Stop and Go adaptive cruise
control does not trigger an emer-
gency stop and its braking capabil-
ity is limited.

INTRODUCTION (2/4)
The Lane Centring function
Using information from a camera, the
Lane Centring function uses the steer-
ing system to direct the vehicle to the
middle of the lane. This function is only
available while the Stop and Go adap-
tive cruise control is activated. ➥ 10 .
If the conditions allow it, the function is
available between:
– 0 mph and 99 mph (160 km/h) ap-
proximately with a vehicle in front;
or
– 37 mph (60 km/h) et 99 mph
(160 km/h) approximately without a
vehicle in front.
The Lane Centring function is a comfort
feature. It is represented by the follow-
ing symbol  ➥ 16 .
Note: in the event of a sharp bend,
the function’s lateral retention capaci-
ties are limited and require the driver to
take immediate action on the steering
wheel.

4
Additional information
Depending on the vehicle, the
“Motorway and Traffic Assistant” func-
tion may be used with other driving aid
functions.
Please note that:
– activating the speed limiter causes
deactivation of the system;
– the system cannot be activated when
the “Park Assist” function is active;
– activation of the “Lane Centring”
function leads to suspension of the
“Lane Departure Warning” or “Lane
Keeping Assist” functions if these
have been activated. They will be re-
activated when the driver decides to
stop the “Lane Centring” function.
For further information on these func-
tions, please see the vehicle user
manual.
INTRODUCTION (3/4)

5
The “Motorway and Traffic Assistant” function is an additional driving aid. This system does not take the place of the
driver.
Therefore, it can under no circumstances replace the driver’s responsibility to respect speed limits and safe distances
and to be vigilant (the driver must always be ready to brake).
The driver must always be in control of the vehicle. The driver must always adapt their trajectory and speed according to the
surroundings and traffic conditions.
The “Motorway and Traffic Assistant” uses the Stop and Go adaptive cruise control function and the Lane Centring function. It
must only be used on a motorway or multi-lane road (separated by a barrier).
It must not be used in heavy traffic, on winding or slippery roads (black ice, aquaplaning, gravel) or during bad weather (fog,
rain, side winds etc.).
There is a risk of accidents.

Computer 1
Receives information from the radar
and camera to determine the vehi-
cle trajectory and speed (acceleration
or braking). Amongst other things, it
controls activation/deactivation of the
system (door opening etc.).
Camera 2
Detects markings on the ground and
the position of vehicles on the various
traffic lanes. It complements the infor-
mation transmitted by the 6 radar.
Make sure the windscreen is not ob-
scured (by dirt, mud, snow, etc.).
Electronic parking brake 3
Keeps the vehicle stationary under cer-
tain conditions.
Power-assisted steering 4
Operates the front wheels to assist the
trajectory of your vehicle according to
details transmitted by the 1 computer.
It also enables detection of the driver's
hands on the steering wheel.
Engine computer 5
It controls and directs the engine to
carry out the required acceleration.
Radar 6
Calculates the distance between your
vehicle and the vehicle in front.
The system's maximum range is ap-
proximately 150 m. This may vary ac-
cording to the road conditions (ground
relief, weather conditions, etc.)
Ensure that the radar area is not ob-
structed (dirt, mud, snow, a badly fitted
front number plate), impacted, modified
(including painting) or hidden by any
accessory fitted on the front of the vehi-
cle (on the grille or logo etc.).
The radar and camera
zones must be kept clean
and free of any tampering in
order to ensure the proper
operation of the system.
Active vehicle control 7
This system provides information on
vehicle dynamics to the computer 1
(speed, lateral acceleration etc.) and
acts on the braking system to control
deceleration and to keep the vehicle
stationary.

STOP AND GO ADAPTIVE CRUISE CONTROL (1/6)
This function cannot be activated when:
– the parking brake is applied;
– the Park Assist function is already
activated. Refer to the description of
“Park Assist” in section 2 of your ve-
hicle user manual.
The message “Adaptive Cruise Ctl un-
available” appears on the instrument
panel.
Activating cruise control
When the vehicle is stationary or
moving at a steady speed, press
switches 2 (SET/-) or 3 (RES/+) to acti-
vate the function and store the current
speed. The minimum cruising speed is
19 mph (30 km/h).
The cruising speed 4 replaces the
dashes and cruise control is confirmed
by the appearance of the cruising
speed in green and warning light .
If you attempt to activate the function at
a speed over 105 mph (170 km/h), the
message “Invalid Speed” appears and
the function remains inactive.
Important: you should keep
your feet near the pedals
and your hands on the
steering wheel at all times
to prepare for any event.
Switching on
Press switch 1.
Warning light  appears in grey, and
the message “Adaptive Cruise Ctl ON”
appears on the instrument panel, ac-
companied by dashes to indicate that
the cruise control function is activated
and waiting to store a cruising speed.

Once a cruising speed is memorised
and the cruise control function is active,
you may lift your foot off the accelera-
tor pedal.
Note: if your vehicle speed is lower
than about 19 mph (30 km/h), the func-
tion uses a default cruising speed of
19 mph (30 km/h). The vehicle will ac-
celerate until it reaches the stored
cruising speed.

Adjusting the following
distance
You can vary the safe distance from the
vehicle in front at any time by pressing
switch 7 repeatedly.
The horizontal distance gauge on the
instrument panel indicates the various
available safe distances:
– distance gauge A: long distance
(corresponding to approximately

Safe distance control
activation
As soon as cruise control is activated,
the default safe distance 5 is displayed
in green on the instrument panel. The
default safe distance corresponds to
approximately two seconds (see follow-
ing pages).
If the system detects a vehicle in your
lane, an outline of a vehicle 6 appears
above the distance gauge 5 on the in-
strument panel.
Your vehicle adapts its speed to that
of the vehicle in front and applies the
brakes if necessary (the brake lights
come on) in order to maintain the dis-
tance displayed on the instrument
panel.
Note: the size of the 6 outline varies ac-
cording to the distance separating you
from the vehicle in front. The larger the
outline, the closer the vehicle in front.

12
Then, release the accelerator pedal:
the cruise control and safe distance
control will automatically resume the
speed and distance instructions that
you had previously selected.
Overtaking manoeuvre
If you wish to overtake the vehicle in
front, activating the indicator will tem-
porarily cancel the safe distance con-
trol and enable an acceleration speed
sufficient to complete overtaking.
STOP AND GO ADAPTIVE CRUISE CONTROL (3/6)
Adjusting the safe distance
(cont.)
– distance gauge B: intermediate dis-
tance 2 (corresponding to approxi-
mately 2 seconds);
– distance gauge C: intermediate dis-
tance 1 (corresponding to approxi-
mately 1.6 seconds);
– distance gauge D: short distance
(corresponding to approximately
1.2 seconds).
The selected distance gauge appears
in green on the instrument panel. The
other gauges remain in grey.
Note: the distance must be set accord-
ing to the traffic level, local regulation
and weather conditions.
The safe distance is adjusted by de-
fault on the distance gauge B.
Exceeding the cruising speed
The cruising speed may be exceeded
at any time by applying the accelerator
pedal.
If it is exceeded, the cruising speed 4
appears in red.
The distance gauge flashes if the dis-
tance between your vehicle and the
vehicle in front is less than the safe
distance selected: the Safe Distance
Control function is no longer active.

In all circumstances, the standby is con-
firmed when the warning lights appear
in grey and the message “Adaptive
Cruise Ctl Disconnected” appears on
the instrument panel.
STOP AND GO ADAPTIVE CRUISE CONTROL (4/6)
Putting the Stop and Go
adaptive cruise control in
standby or switching it off
does not cause a rapid re-
duction in speed: you must brake
by applying the brake pedal if nec-
essary.
The  warning light disappears to
confirm that the function is deactivated.
Putting the function on
standby
You can set the function to standby
when:
– you press switch 8 (0);
– you apply the brake pedal while the
vehicle is moving.
The function is deactivated by the
system if:
– you put the gearbox in P, R or N;
– you unbuckle the driver’s seatbelt;
– you open one of the opening ele-
ments;
– you press the engine start/stop
button;
– the slope is too steep;
– the vehicle speed is above 112 mph
(180 km/h);
– certain driving aids and correction
devices are triggered (active emer-
gency braking, ABS, ESC, etc.)
Stopping the vehicle and
setting off
If the vehicle in front slows down, the
system adapts its speed to bring the
vehicle to a complete stop if necessary
(e.g. in heavy traffic). The vehicle stops
a few metres from the vehicle in front.
The Stop and Start function can put the
engine in standby. Refer to the section
on “Stop and Start function” in the vehi-
cle user manual.
When the vehicle in front sets off again:
– if the stop does not exceed about
three seconds, the vehicle sets off
automatically without any action by
the driver;
– if the stop exceeds about three sec-
onds, you must apply the accelera-
tor pedal or press button 3 (RES/+) in
order for the vehicle to set off again.
The message “Press RES/+ or ac-
celerate” appears on the instrument
panel to confirm.
If the stop exceeds about three min-
utes, the electronic parking brake is au-
tomatically applied and the Stop and
Go adaptive cruise control is deacti-
vated.

STOP AND GO ADAPTIVE CRUISE CONTROL (5/6)
Exit from standby
Based on the stored cruising speed
If a speed is stored, it can be recalled,
once you are sure that the road con-
ditions are suitable (traffic, road sur-
face, weather conditions, etc.). Press
switch 3 (RES/+) in the range of con-
firmed speeds.
When the stored speed is recalled, acti-
vation of the cruise control is confirmed
by the illumination of the cruising speed
in green.
Note: if the stored speed is higher than
the current speed, the vehicle will ac-
celerate to reach that speed.
Based on the current speed
When the cruise control is set to
standby, pressing switch 2 (SET/-) re-
activates the cruise control function
without taking into account the stored
speed: it is the speed at which the vehi-
cle is moving that is taken into account.
“Take control of the vehicle”
warnings
In some situations (e.g. coming upon
a much slower vehicle, vehicle in
front changing lanes quickly etc.), the
system may not have time to react.
E
F
Depending on the situation, the system
sounds a beep associated with:
– the orange alert E if the situation re-
quires the driver’s attention;
or
– the red alert F accompanied by the
message “Brake”, if the situation re-
quires the driver’s immediate action.
In all situations, react accordingly
and perform the appropriate ma-
noeuvres.

mately 37 mph (60 km/h), without
any vehicle in front;
– the vehicle touches or breaches a
line;
– the system is temporarily disrupted
(for example: camera obscured by
dirt, mud, snow,condensation, etc.).
Certain actions carried out by the driver
also suspend the Lane Centring func-
tion:
– activating the indicators;
– turning the steering wheel.
Standby of the function is confirmed by
the 2  warning light and the left-
hand and right-hand line indicators 3
appearing in grey on the instrument
panel.
You can affect the vehicle trajec-
tory at any point by turning the
steering wheel.
LANE CENTRING (2/5)

18
“Hands on steering wheel”
alert
When the Lane Centring function no
longer detects your hands on the steer-
ing wheel, several warning levels will
be triggered:
– after 15 seconds, the message:
“Keeping hands on steering wheel” is
shown in yellow on the instrument
panel 4;
LANE CENTRING (3/5)
– after approximately 30 seconds,
the message: “Keeping hands on
steering wheel” appears on the in-
strument panel 4 and the warning
light 5  appears in red, accom-
panied by an audible signal of gradu-
ally increasing volume;
– after approximately 45 seconds,,
the audio sources go on standby, the
audible signal sounds continually,
the warning light 5  is switched
off and the message: “Lane center-
ing deactivated” appears in red on
the instrument panel 4: the Lane
Centring function is deactivated.
Note: in some situations, the Lane
Centring function may no longer detect
your hands on the steering wheel and
may sound a signal:
– the vehicle is moving along a long
straight lane and the driver’s hands
are immobile on the steering wheel;
– the driver is holding the steering
wheel very lightly;
– ...
If the Lane Centring function is deac-
tivated due to the driver’s hands not
being detected on the steering wheel,
the Stop and Go adaptive cruise control
function remains in operation.
In the first two alert levels, when the
system again detects the presence
of the driver’s hands on the steering
wheel, the system stops the alerts.
The function continues to direct the
vehicle to the centre of the lane.

In the case of a sharp bend
In the case of a sharp band, and de-
pending on the vehicle speed, the func-
tion’s side retaining capacities will be
limited and require the driver to carry
out immediate action on the steering
wheel so that the function can continue
to maintain the vehicle in the centre of
the lane.
If the driver does not intervene, the
function triggers the vibration of the
steering wheel to signal that the vehi-
cle is about to breach a line and that
the driver needs to carry out immediate
action.
The 2  warning light and the left-
hand or right-hand line indicator 3
appear in red on the instrument panel.
