air outlets and the air extractor in the boot free
from obstructions.
► Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►  Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in perfect working order.
►  If the system does not produce cold air,
switch it off and contact a dealer or a qualified
workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power, enhancing the towing capacity.
Avoid driving for too long with the
ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►  Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly.
We recommend using a composite passenger
compartment filter. Thanks to its special
active additive, this type of filter helps to
purify the air breathed by the occupants
and keep the passenger compartment clean
(by reducing allergic symptoms, unpleasant
odours and greasy deposits).
►  To ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop & Start, refer
to the corresponding section.

Air conditioning on / off
The air conditioning system is designed to
operate effectively in all seasons, with the
windows closed.
It is used to:
– lower the temperature in summer,
– increase the effectiveness of the demisting in
winter, above 3°C.
►  Press button 4 to activate/deactivate the air
conditioning system.
Air conditioning does not operate when
the air flow is disabled.
To obtain cool air more quickly, enable interior
air recirculation for a brief period. Then return
to the intake of exterior air.
Switching off the air conditioning may result in
some discomfort (humidity or misting).

Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit heating up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use of
engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine immobiliser
system, with a code that must be recognised in
order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/Switching off the
engine
The electronic key must be present in the
passenger compartment.
For versions equipped with Proximity Keyless
Entry and Start, the electronic key is also
detected in the boot.
If it is not detected, a message is displayed.
Move the electronic key so that the engine can
be started or switched off.
If there is still a problem, refer to the "Key not
detected - Back-up starting or Back-up switch-
off" section.

Technical data09
Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.
The maximum power corresponds to the
value type-approved on a test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a dealer or a
qualified workshop.
Weights and towed loads
The weights and towed loads relating to
the vehicle are indicated on the registration
document, as well as in sales brochures.
These values are also indicated on the
manufacturer's plate or label.
For more information, contact a dealer or a
qualified workshop.
The GTW (Gross Train Weight) values and the
towable loads listed are valid for a maximum
altitude of 1,000 metres. The towable load must
be reduced by steps of 10% for each additional
1,000 metres.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
When exterior temperatures are high, the
vehicle performance may be limited in
order to protect the engine. When the exterior
temperature is higher than 37°C, reduce the
towed weight.
Towing even with a lightly loaded vehicle
can adversely affect its road holding.
Braking distances are increased when towing
a trailer.
When using a vehicle to tow, never exceed a
speed of 62 mph (100 km/h) (observe the local
legislation in force).
