Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen, the
nozzles, the vents, the air outlets and
the air extractor in the boot free from
obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working
o r d e r.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms,
bad odours and greasy deposits). If after an extended stop in sunshine,
the interior temperature is very high, first
ventilate 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.
The condensation created by the air
conditioning results in a
discharge of water
under the vehicle which is per fectly normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a
comfortable temperature
in the passenger compartment, you may
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.
F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold
air, switch it off and contact the dealer
network 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 and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.

Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBD)It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by
a
reduction in the resistance of the pedal and
an increase in the effectiveness of the braking.
When lit up continuously, this
warning lamp indicates a
fault with
the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
If these warning lamps come on,
accompanied by an audible signal
and a
message, this indicates a fault
with the electronic brake force
distribution (EBFD).
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS system may
be indicated by slight vibration felt at the
brake pedal. In case of emergency braking, press
ver y hard without releasing the
pressure at all.

Activation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a
problem with grip or trajectory.
This is indicated by flashing of this
warning lamp in the instrument
panel.
Deactivation
In extremely severe conditions (deep snow,
mud, etc.), if you are unable to move off, it
may be useful to temporarily deactivate these
systems so that the wheels can spin and allow
the vehicle to regain grip.
You must stop as soon as it is safe to do so.
In both cases, have the system checked in the
dealer network or by a

qualified workshop as
soon as possible.

F Press this button.
If the indicator lamp in the button comes on,
this indicates that the systems are deactivated.
Reactivation
These systems are reactivated automatically
every time the ignition is switched off, or
from 30 mph (50 km/h), except for the 1.6 l
petrol and (THP 165, THP 155, THP 150) and
PERFORMANCE engines.
F

P
ress this button again to reactivate them
manually.
Operating fault
Illumination of this warning lamp
and the indicator lamp in the button,
accompanied by an audible signal
and a
message, indicate a fault with
these systems.
Have them checked by an
authorised dealer or by a
qualified
workshop. ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used in the dealer network.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Seat belts
Front seat belts
The front seat belts are fitted with
a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a
front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of
the seat belt on the passenger's chest, thus
improving their protection.
Fastening
F Pull the strap then insert the tongue in the buckle.

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude.
Please respect the maximum towable
weights.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 600


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a
genuine
DS
AUTOMOBILES towbar is used.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1
to 2 minutes after the vehicle
comes to a
stop, to facilitate its cooling.
