Ease of use and comfort
3The setting is associated with AUTO mode only.
However, when AUTO mode is deactivated, the
previous selection is retained.
Changing the setting does not reactivate AUTO
mode if this was deactivated.
In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, in order to
limit the delivery of cold air into the passenger
compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer than
the comfort setting requested, there is no
need to alter the value displayed to reach
the required level of comfort more quickly.
The system automatically corrects the
temperature difference as quickly as possible.
Air flow adjustment
► Press one of the buttons 2 (- or +) to increase
or decrease air flow.
The air flow symbol (a fan) is filled in according
to the request.
When the air flow is reduced to a minimum,
ventilation stops.
"OFF " is displayed alongside the fan.
Adjusting the air distribution
► Press the buttons 3 to adjust the air flow
distribution inside the passenger compartment.
Windscreen.
Central and side air vents.
Footwells.
Each press on a button activates or deactivates
the function.
All three buttons can be activated simultaneously. In this case, priority is
given to the air flows from the central and side
air vents, and from those in the passenger
footwells.
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 turn the air conditioning on/
off.
When the indicator lamp is on, the air
conditioning function is activated.
The air conditioning cannot operate when the air flow adjustment is set to OFF.
Ventilation function with the
ignition on
When the ignition is switched on, you can
use the ventilation system to adjust the air
flow settings and the air distribution in the
passenger compartment for a duration which
depends on the battery charge.
This function does not operate the air
conditioning.
Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
When required, this function also allows
faster heating or cooling of the air in the
passenger compartment.
► Press button 6 to recirculate the interior air or
allow the intake of exterior air.
Avoid prolonged use of interior air recirculation (due to the risk of misting
and deteriorating air quality).

Operation
Main conditions for operation
– The driver ’s door must be closed.– The driver's seat belt must be fastened.– The state of charge of the battery must be sufficient.– The temperature of the engine must be within its nominal operating range.– The outside temperature must be between 0°C and 35°C.
Putting the engine into standby
(STOP mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop.
– With a manual gearbox: with the gear lever in
neutral and the clutch pedal released.
– With an automatic gearbox: with the gear
selector in position D or M, the brake pedal
depressed until the vehicle stops or the gear
selector in position N, with the vehicle stationary.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if all of the
conditions for operation are not met and in the
following cases.
– Steep slope (ascending or descending).– Vehicle has not exceeded 6 mph (10 km/h) since the last engine start (with the key or the
“START/STOP” button).
– Needed to maintain a comfortable temperature in the passenger compartment.– Demisting active.– Braking assistance being used.In these cases, this indicator lamp flashes for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle
has reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Engine restarting (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
► With a manual gearbox : with the clutch
pedal fully depressed.
► With an automatic gearbox :• With the selector in position D or M: with the

Under-inflation detection
This system automatically checks the pressures of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding.– lengthens braking distances.
– causes premature wear of the tyres.– increases fuel consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
► Reduce speed immediately , avoid excessive steering movements and avoid sudden braking.► Stop the vehicle as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
► Using a compressor , such as the one in the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make this check immediately, drive carefully at reduced speed.

128
Practical information
► Refit protective plug 2 to carrier 1.► Carefully stow the towball in its bag away from knocks and dirt.
Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure
jet wash, the towball must be removed and the
protective plug fitted to the carrier.
Apply the label provided to a clearly visible area, close to the carrier or in the
boot.
Go to a CITROËN dealer or a qualified
workshop for any work on the towbar system.
Towing device
Load distribution► 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 load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it
must still be fitted in accordance with the
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as air conditioning, heated rear
screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched to
economy mode and the active functions are put
on standby.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free system
of your audio system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
– For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the
12 V battery,
refer to the corresponding section.
Roof bars
For safety reasons and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied
with the roof bars.

134
Practical information
For more information on the precautions
to take before any work on the 12 V battery, refer to the corresponding section.
Versions equipped with Stop & Start are fitted with a 12 V lead-acid battery of specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine oil is changed.
Particle filter (Diesel)
When the particle filter is approaching saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add 0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
