Ventilation
Air intake
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 the
driver:
-
d
irect arrival in the passenger
compartment (air intake),
-

p
assage through a heating circuit (heating),
-

p
assage through a cooling circuit (air
conditioning).

in the Air conditioning menu of the touch
screen

The air distribution in the passenger
compartment can be adjusted by combining the
use of several vents.

Centre and side vents.
The air distribution can be varied by using
more than one button: illumination of the
button indicates that air is distributed in that
direction; no illumination indicates that air is not
distributed in that direction.
In AUTO mode, all three buttons are off. Switching off Switching on
Air conditioning On/Off
The air conditioning is designed to operate
efficiently in all seasons, with the windows
closed.
It allows you:
-

i
n summer, to lower the temperature,
-

i
n winter, above 3 °C, to improve demisting.
Avoid prolonged operation of the air
recirculation function (risk of misting
and of deterioration of the air quality).
When the indicator lamp is off, the intake of
exterior air is active.
When the indicator lamp is on, air recirculation
is activated, the intake of exterior air is
inhibited.
F

P
ress this button to choose
the mode for air entry to the
passenger compartment.
The intake of exterior air avoids misting of the
windscreen and side windows.
Air recirculation prevents exterior odours
and smoke from entering the passenger
compartment.
This function also allows faster heating
or cooling of the air in the passenger
compartment.

When towing
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 per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
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 the 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 Adjusting the
headlamp beam height , refer to the
corresponding section.

Bonnet
F Open the left-hand front door.
F
L
ift the safety catch and raise the bonnet. F
U nclip the stay from its housing and place
it in the support slot to hold the bonnet
open.
Opening
F Pull the release lever, located at the bottom of the door aperture, towards you. Before doing anything under the
bonnet, switch off the Stop & Start
system to avoid any risk of injury
resulting from an automatic change to
START mode.
The cooling fan may star t after switching off the engine: take care with ar ticles and
clothing that might be caught by the fan blades. Do not open the bonnet under very
windy conditions.
The location of the interior bonnet
release lever prevents opening of the
bonnet when the left-hand front door
is shut.
When the engine is hot, handle the
exterior safety catch and the stay with
care (risk of burns), using the protected
area.
When the bonnet is open, take care not
to damage the safety catch.
Because of the presence of electrical equipment under the bonnet, it is recommended that
exposure to water (rain, washing, ...) be limited.
Closing
F Take the stay out of its support slot.
F C lip the stay back into its housing.
F

L
ower the bonnet and release it at the end
of its travel.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at
any time (even with the ignition off).
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.Checking using the dipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.
F
T
ake the dipstick by its coloured grip and
remove it completely.
F

W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R
efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between the marks A
and B .
It is normal to top-up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level,
and top-up if necessary, every 3 000 miles
(5 000 kms). Check all of these levels regularly, in line with the manufacturer's service schedule. 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.
To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes. A = MA X
B = MIN
If you find that the level is above the A mark or
below the B mark, do not star t the engine .
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top-up the engine oil.
