on and off
Fig. 142 Parking sensor
system sensors on the
front bumper
The parking sensor system assists the driver when parking. If the vehicle is
approaching an obstacle, an intermittent audible warning is emitted. The
shorter the distance, the shorter the intervals between tones. If the vehicle
is too close to the obstacle, the audible warning becomes constant. Switching the parking sensor system on and off
●
Press the
button ⇒
Fig. 141 when the ignition is switched on.
● Automatic on: select reverse gear.
● Automatic off: drive faster than 15 km/h (10 mph).
The button lights up when the function is switched on.
Things to note regarding the parking sensor system
● The parking sensor system sometimes registers water on the sensors as
an obstacle.
● If the distance does not change, the warning signal will sound less loud-
ly after a few seconds. If the continuous signal sounds, the volume will re-
main constant.
● When the vehicle moves away from the obstacle, the beeping sound au-
tomatically switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
● If the electronic parking brake is engaged or the selector lever is set to
P, no audible warning will be emitted.
● Your Technical Service can adjust the volume of the warning signals.
Note
If the parking sensor system is faulty, a constant audible warning will be
emitted the first time it is switched on and the button will flash. Switch the
parking sensor system off using the button and take the vehicle to a speci-
alised workshop to have the system checked as soon as possible.

Driving
Parking
● Parking parallel to the road: Drive next to the gap at a speed of no more
than 40 km/h (25 mph) and at a distance of between 0.5 m and 2 m.
● Parking perpendicular to the road: Drive next to the gap at a speed of no
more than 20 km/h (12 mph) and at a distance of between 0.5 m and 2 m.
● The best parking results will be achieved if you position the vehicle as
parallel as possible to the line of parked cars or the kerb.
● When a suitable parking place is displayed on the instrument panel,
stop and select reverse gear.
● Follow the instructions given on the instrument panel display
● Then, release the steering wheel when the warning signal sounds ⇒
:
The system will move the steering wheel! Observe the surrounding area.
● Observe the surrounding area and accelerate carefully at a maximum of
up to 7 km/h (4 mph).
● The park assist system is only responsible for moving the steering wheel
during the manoeuvre. The driver applies the accelerator, the clutch, the
gears and the brake.
● Follow the instructions given by the park assist system until the ma-
noeuvre is completed.
● The park assist system steers the vehicle forwards and backwards until
it is in a straight position in the parking space.
● The manoeuvre is complete when the corresponding indication is given
on the instrument panel display.
Stopping the parking manoeuvre
The park assist system stops the manoeuvre in the event of one of the fol-
lowing:
● Press button
.
● Driving faster than 7 km/h (4 mph).
● The driver moves the steering wheel.
● The parking manoeuvre has not been completed after six minutes since
the park assist system was activated. ●
A sliding door is opened. To restart the manoeuvre, close the sliding
door and press the button
again.
● There is a system malfunction (system temporarily unavailable).
● The ASR system is switched off or the ASR or ESC is working.
WARNING
The steering wheel turns quickly by itself when parking using the park
assist system. Placing your hand between the steering wheel spokes
could lead to injuries.
Note
● The park assist system has its limitations. For example, it is not possible
to park on tight bends using the park assist system.
● Even if the park assist system recognises that there is not enough space
for parking the vehicle, the instrument panel display will still show this
place. In this case, the parking manoeuvre should not be requested.
● Changing gears between forward and reverse gears before indicated
(that is, before the signal from the parking sensor system) the parking re-
sults may not be ideal.
● For parallel parking (parallel to the road), a sound will tell the driver
when they must change from forward gears to reverse; the signal from the
parking sensor system does not indicate changes of direction.
● The park assist can also be activated afterwards, if you pass close to a
parallel parking space at a maximum of 40 km an hour (25 mph) or close to
be perpendicular parking space at about 20 km an hour (12 mph) then
press the button
.
● The progress bar on the screen of the instrument panel shows a display
of the relative distance to be covered.
● When the Park Assist system is turning the steering wheel of the stop-
ped vehicle the symbol is also displayed. Press on the brake pedal so
that the steering can turn with the vehicle at a standstill and thus reduce
the number of manoeuvres.

● A suitable parking space length is at least 1.1 m greater than the length
of the vehicle.
● If the results of the park assist system are not as good after changing
the wheels, the system must memorise the perimeter of the new wheels.
This process is performed automatically while the vehicle is in motion. To
help this process, turn slowly (at less than 20 km/h (12 mph)), e.g. in an
empty car park.
Leaving a parking space using the Park Assist system
Driving off
● Switch on the engine.
● Press button
. When the function is enabled, the button
⇒ Fig. 145
will light up.
● Apply the turn signal for the side on which you want to leave the parking
space.
● Select reverse gear.
● Follow the instructions given by the park assist system.
● When the next indication appears, release the steering wheel ⇒

● The ASR system is switched off or the ASR or ESC is working.
WARNING
The steering wheel turns quickly automatically when leaving a parking
space using the park assist system. Placing your hand between the steer-
ing wheel spokes could lead to injuries.
Park Assist brake operation
The Park Assist system helps the driver by braking automatically. Automatic
braking does not relieve the driver of responsibility for controlling the accel-
erator, brake and clutch ⇒
.
Braking to avoid damage at excess speed
It is possible that the system operates the brakes to reduce excess speed.
The parking manoeuvre can then continue. The brakes will intervene during
each parking process.
Braking to minimise damage
When approaching an obstacle, the vehicle may brake automatically. In cer-
tain circumstances (for example, storm, detection of ultrasounds, vehicle
status, load, inclination), the Park Assist system may stop the vehicle com-
pletely before an object.
207
Driving
● Press the foot brake ⇒
!
Following the intervention of the brakes, the Park Assist will stop.
WARNING
Despite the assistance provided by the park assist system, do not run
any risks when parking. The system is not a replacement for driver
awareness.
● Always be ready to brake.
● Automatic brake intervention will end after 1.5 seconds approximate-
ly. Following automatic intervention of the brakes, stop the vehicle your-
self.

Cruise control system*
Introduction
The cruise control system (CCS) is able to maintain the set speed when driv-
ing forwards from approx. 20 km/h (12 mph).
The CCS only slows down by reducing the accelerator but not by braking.
⇒
.
Additional information and warnings:
● Changing gear ⇒ page 175
● Accessories, parts replacement, repairs and modifications ⇒ page 260
WARNING
Use of the cruise control could cause accidents and severe injuries if it is
not possible to drive at a constant speed maintaining the safety distance.
● Do not use the CCS in heavy traffic, if the distance from the vehicle in
front is insufficient, on steep roads, with several bends or in slippery cir-
cumstances (snow, ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or on unpaved roads.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● To avoid unexpected operation of the cruise control system, turn it off
every time you finish using it.
● It is dangerous to use a set speed which is too high for the prevailing
road, traffic or weather conditions.
● When travelling down hills, the CCS cannot maintain a constant
speed. The vehicle tends to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the vehicle.
