In cold weather and when the engine
is cold, the air flow will gradually reach
its optimum level, taking account of the
weather and the desired comfort level so
as to avoid distributing too much cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no need
to change the value displayed in order to
obtain the desired comfort. The system
corrects the difference in temperature
automatically and as quickly as possible.
Temperature adjustment on driver/
passenger side
The driver and front passenger can each set
the temperature to suit their requirements.
The value shown on the display is a level
of comfort, not a temperature in Celsius or
Fahrenheit.F

T
urn the dial to the left to lower
the value and to the right to
raise it. A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
It is also recommended to avoid a left /right
setting difference of more than 3.

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). 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:
do not drive for too long with the ventilation
switched off.
Do not keep air recirculation set for an
extended period. If after an extended stop in sunshine, the
interior temperature is very high, first 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.
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 can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, a break every two hours is
strongly recommended.
In bad weather, drive smoothly, anticipate the
need to brake and increase the distance from
other vehicles.Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
Do not park and do not run the engine,
the vehicle is stationary, in areas where
substances and combustible materials
(dry grass, leaves ...) can come into
contact with the hot exhaust system – Risk
of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle. If you are obliged to drive through water:
-

c
heck that the depth of water does not
exceed 6 inches (15 cm), taking account
of waves that might be generated by other
users,
-
d
eactivate the Stop & Start function,
-
d
rive slowly as possible without stalling. In
every case, do not exceed a speed of 6 mph
(10 km/h),
-
d
o not stop and do not turn off the engine.
On leaving the flooded road, and as soon as
safety conditions permit, brake lightly several
times to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact the dealer network or a qualified
workshop.

In case of towing
Driving with a trailer places greater
demands 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.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
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.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature 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 towed load on a long 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.
Braking
Towing a trailer increases the braking distance.
To 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
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.

Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a specific code. When the ignition is switched
on, this code must be recognised to allow the
engine to be started.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.
Starting/Switching off the
engine with the key
Ignition switch
It has 3 positions:
- position 1 (Stop): inserting and removing
the key, steering column locked,
-
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-
position 3 (Starting) .
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reser ve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preser ve the remaining
battery charge. Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch
and could cause a malfunction.
Switching off the engine leads to a loss of
braking assistance.
Starting the engine
With the parking brake applied and the gearbox
in neutral or position N
or P:
F

d
epress the clutch pedal fully (manual
gearbox),
or
F

p

switch off the ignition. Wait a few moments
before operating the starter motor again.
If the engine does not start after several
attempts, do not keep trying: you risk
damaging the starter motor or the engine.
Contact the dealer network or a qualified
workshop.
In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
spe ed. Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving
