Conditions requiring the key to restart the
engine
The engine must be started manually under
the following conditions:
● If the driver unbuckles his/her seat belt.
● If the driver door is opened.
● If the bonnet is opened.
● In vehicles with a manual gearbox: if a gear
has been selected.
Switching Start-Stop mode on and off
manually
● Press the button on the centre console
››› Fig. 136 .
● The b utt
on will light up when the Start-Stop
function is switched off.
The engine will start immediately if the vehi-
cle is in Stop mode when it is switched off
manually. WARNING
The brake servo and the power steering do
not work when the engine is switched off.
● Never allow the vehicle to move when the
engine is switched off. CAUTION
Using the Start-Stop function for a long peri-
od at very high outside temperatures could
damage the vehicle's battery. Note
● In some cases, you may have to restart the
vehicle using the key. Observe the corre-
sponding message on the instrument panel
display.
● If the steering wheel is turned more than
270°, Stop will not function; however, the an-
gle of steering wheel turn does not affect
starting the vehicle. Parking sensor system*
Introduction The parking sensor system assists the driver
when parking. When the vehicle approaches
an obstacle, forwards or backwards, an inter-
mittent audible warning will be heard, higher
or lower depending on the distance. The
shorter the distance, the shorter the intervals
between tones. If the vehicle is too close to
the obstacle, the audible warning becomes
constant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.
The sensor system on the bumpers transmit
and receive ultrasound. Using the ultrasound
signal (transmission, reflection from the ob-
stacle and reception), this system continu-ously calculates the distance between the
bumper and the obstacle. WARNING
The parking sensor system and the optical
parking system cannot replace driver aware-
ness.
● The sensors have blind spots in which ob-
stacles and people are not registered.
● Always observe the area around the vehi-
cle, as the sensors do not always detect
small children, animals or objects.
● The surface of certain objects and some
clothing do not reflect the ultrasound signals
from the parking distance system. The sys-
tem cannot detect or incorrectly detects
these objects and people wearing these
types of clothes.
● External sound sources can affect the park-
ing distance aid signals. In this case, under
certain circumstances, people and objects
will not be detected. CAUTION
● The sensors may not always be able to de-
tect objects such as trailer draw bars, thin
rails, fences, posts, trees and open boots,
etc. This could result in damage to your car.
● Although the parking sensor system de-
tects and warns of the presence of an obsta-
cle, the obstacle could disappear from the an-
gle of measurement of the sensors if it is too
high or low and the system would no longer » 159

Operation
If the system detects that a trailer has been
connected electrically, the electrical equip-
ment on the trailer will receive voltage
through this connection (pins 9 and 10). Pin
9 has a permanent live. This powers, for ex-
ample, the trailer's interior lighting. Electrical
devices such as a fridge in a caravan only re-
c eiv
e electrical power if the engine is running
(through pin 10).
The earth wires, pin 3 and pin 13, should not
be connected to each other to avoid over-
loading the electrical system.
If the trailer has a 7-contact connector , you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available.
Trailer cable
Always secure the trailer cable to the towing
vehicle correctly. Leave a little bit of slack in
the cable for turning. However, ensure that
the cable does not rub off the ground while
driving.
Trailer rear lights
Check the trailer rear lights to ensure they
work correctly and remain legal. Ensure that
the trailer does not use more than the maxi-
mum power ›››

ailer connected to the anti-theft alarm:
● When a vehicle comes from the factory fit-
ted with an anti-theft alarm and tow hitch.
● When the trailer is connected to the vehicle
using the socket.
● When the vehicle and trailer electrical sys-
tems work correctly and are not damaged.
● When the vehicle is locked using the vehi-
cle key and the anti-theft alarm is turned on.
When the vehicle is locked, the alarm is trig-
gered when the electrical connection be-
tween the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer.
Otherwise, the tilt sensor may erroneously
activate the alarm.
Trailer with rear LED lights
For technical reasons, trailers fitted with rear
LED lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not trigger if the electrical connection with
the trailer is cut if it has rear light with light-
emitting diodes. WARNING
Erroneous or unsuitable connection of elec-
tric cables may supply energy to the trailer
causing an anomaly in the vehicle electronics that could result in an accident with serious
consequences.
●
All work on the electrical system must be
carried out only by a specialised workshop.
● Never connect the trailer's electric system
to the electrical connections of the rear lights
or any other power sources. CAUTION
Do not leave the trailer connected to the vehi-
cle when parked; places on its support wheel
or its supports. For example, when changing
the load or a puncture, the vehicle will be
pushed up or down. The force acting on the
tow hitch and the trailer could damage the
vehicle or the trailer. Note
● In the event of a fault in the vehicle or trail-
er electrical system or in the event of prob-
lems with the anti-theft alarm system, have
the system checked by a specialised work-
shop.
● If the trailer accessories use energy from
the power socket when the engine is stop-
ped, the battery will be discharged.
● For technical reasons, trailers fitted with
rear LED lights cannot be connected to the
anti-theft alarm system.
● If the vehicle battery is running low, the
electrical connection with the trailer is auto-
matically cut. 184

Checking and refilling levels
carried out by a specialised workshop if you
are uncertain. Negligent work can cause seri-
ous injury. WARNING
If the vehicle moves unexpectedly, this could
cause serious injury.
● Never work under the vehicle if it has not
been immobilized. If you must work under-
neath the vehicle with the wheels in contact
with the ground then it should be parked on
flat ground, the wheels should be prevented
from moving and the key should be removed
from the ignition.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. The jack is not intended for this kind of
work and its failure could lead to severe inju-
ries. WARNING
The engine compartment is a dangerous area
capable of causing serious injury.
● For all type of work, always take the utmost
precautions, work carefully and note the gen-
eral safety standards in force. Never take per-
sonal risks.
● Never work on the engine or in the engine
compartment if you are not familiar with the
necessary operations. If you are not sure
about procedures then visit a specialised
workshop to carry out the necessary work. Working incorrectly can cause serious inju-
ries.
●
Never open the bonnet if you see steam or
coolant escaping from the engine compart-
ment. This may cause serious burns. Always
wait until you cannot see or hear the sound of
steam or coolant coming from the engine
compartment.
● Always allow the engine to cool down be-
fore opening the bonnet.
● Contact with hot elements of the engine
and the exhaust system can cause burns.
● Once the engine has cooled, follow the in-
structions below before opening the bonnet:
– Turn on the electronic parking brake and
place the gear selector lever in P or the
gearbox lever in neutral.
– Remove the key from the ignition.
– Keep children away from the engine com-
partment and never leave them unsuper-
vised.
● When the engine is warm or hot, the cool-
ing system is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– Carefully and slowly unscrew the cap an-
ticlockwise, gently pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth. ●
When refilling liquids, avoid spilling them
on parts of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. WARNING
The high voltages of the electrical system can
give electric shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
system. The battery could explode.
● To minimise the risk of electric shock and
serious consequences while the engine is
running or starting the engine, note the fol-
lowing:
