Comfort








Vent ilat ion
The air circulating in the passenger compartment
is filtered and originates either from the outside via
the
grille located at the base of the windscreen or from the inside in air recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by thedriver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).
Control panel
The controls of this system are accessible
in the " Air conditioning " menu of the touchscreen tablet A .
The demisting/defrosting controls for the
windscreen and rear screen are located on theleft of the touch screen tablet.

Practical information

Driving advice


Distribution of loads
)Distribute the load in the trailer so that theheaviest 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. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.

Side wind
)Take into account the increased sensitivity
to side wind.
Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y controlled, its cooling capacity is not dependent on the engine speed.
)
To lower the engine speed, reduce your speed.
The maximum towed load on a long incline
depends on the
gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and the
STOPwarning lamp come on, stop the vehicle and switch off
the engine as soon as possible.



Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.

R
efer to the "Technical data" section for detailsof the weights and towed loads which apply to your vehicle.


The rear parking sensors will be
deactivated automatically if a genuineCITROËN towbar is used.

When not towing a trailer, remove thequickly-detachable tow ball beforedriving.

Practical information








Very cold climate screen *
Removable protective screen which prevents the accumulation of snow at the radiator cooling fan.
)Offer up the very cold climate screen to
the front of the lower section of the frontbumper.)Press around its edge to engage its fixingclips one by one.

)
Use a screwdriver as a lever to release each fixing clip in turn.

*
According to country.
Do not for
get to remove the very cold climatescreen when:


- the ambient temperature exceeds 10

Checks











Bonnet
Open the left hand front door.


Do not open the bonnet under verywindy conditions.When the engine is hot, handle the exterior safety catch and the stay with care (risk of burns), using the protected area.
)
Lift the safety catch and raise the bonnet.

)Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.

Opening
)Pull the release lever, located at the bottom
of the door aper ture, towards you.
Before doing anything under the bonnet,switch off the Stop & Start system toavoid any risk of injury resulting from anautomatic change to START mode.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.


Closing
)Take the stay out of its suppor t slot. )Clip the stay back into its housing. )Lower the bonnet and release it at the end of its travel. )Pull on the bonnet to check that it haslatched correctly.
When the bonnet is open, take care not to damage the safety catch.

Checks






Checking levels


Ta k e c a r e w h e n w o r k i ng under the bonnet, as certain areas of the engine may be extremelyhot (risk of burns) and the cooling fan could star t at any time (even with the ignition off).
Oil level

The check is carried out either when
the ignition is switched on using theoil level indicator in the instrument
panel, or using the dipstick.
Engine oil change

Refer to the maintenance and warranty guidefor details of the interval for this operation.
In order to maintain the reliability of the engine
and emission control system, the use of
additives in the engine oil is prohibited.

Oil specifi cation

The oil must be the correct grade for your engine and conform to the manufacturer'srecommendations.
Check all of these levels re
gularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Dipstick

There are two marks on the dipstick:
A= maximum
If you fill past this mark, contact a CITROËN dealer or a qualified workshop. B= minimum
Top up the level through the
oil filler orifice, using thecorrect grade of oil for your engine. The level must never be below this mark.
It will onl
y be correct if the vehicle is on level ground and the engine has been off for more
than 30 minutes.It is normal to top up the oil level between
two ser vices (or oil changes). CITROËNrecommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms).
After topping up the oil, the check whenswitching on the ignition with the oil level
indicator in the instrument panel is not valid
durin
g the 30 minutes after topping up.

Checks

The coolant level should be closeto the "MA X" mark but should never exceed it.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the
engine before carrying out any work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When
the pressure has dropped, remove the cap and
top up the level.


Fluid specifi cation

The coolant must conform to the
m
anufacturer's recommendations. Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Brake fluid level

Changing the fl uid

Refer to the maintenance and warranty guidefor details of the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet the
DOT3 or DOT4 standard.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.
When the engine is warm, the temperature of
the coolant is regulated by the fan.
