Warning and indicator lamps

Visual indicators which inform the driver of the occurrence of a malfunction (warn-
ing lamp) or of the operation of a system (operation or deactivation indicator lamp).

When the ignition is switched on
Certain warning lamps come on for a few seconds when the ignition is switched on.
When the engine is started, these warning lamps should go off.
If they remain on, before moving off, refer to the information on the warning lamp
in question.

Associated warnings
The illumination, fi xed or fl ashing, of certain warning lamps may be accompanied
by an audible signal and the display of a message.

Warning lamps
When the engine is running or the vehicle is being driven, the illumination of one of the fol-
lowing warning lamps indicates a malfunction which requires action on the part of the driver.
The warning comes on in the instrument panel.

If your vehicle has a screen, a
warning lamp coming on is al-
ways accompanied by the dis-
play of an additional message,
to assist you in identifying the
problem.
If you encounter any problems,
do not hesitate to contact a
CITROËN dealer or a qualifi ed
workshop.

VENTILATION

Air intake

The air circulating in the passenger com-
partment is fi ltered 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:


- direct arrival in the passenger com-
partment (air intake),

- passage through a heating circuit
(heating),

- passage through a cooling circuit
(air conditioning).



Control panel

The controls of this system are grouped
together on control panel A
on the centre
console.

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).


The check is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel, or us-
ing the dipstick.
It will only 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 be-
tween two services (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping up.


















Oil level


Engine oil change
Refer to the maintenance and warranty
guide for 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.











Brake fluid level


Changing the fl uid
Refer to the maintenance and warranty
guide for details of the interval for this
operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations.












Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold, un-
screw the cap to check the level.











Coolant level


The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan.
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 pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Check all of these levels regularly, in
line with the maintenance and warranty
guide. Top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.








The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might become caught by the
fan blades.
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

VERY COLD CLIMATE SCREEN *


* According to country.


Fitting




Offer up the very cold climate
screen to the front of the lower sec-
tion of the front bumper.


Press around its edge to engage its
fi xing clips one by one.



Removal




Use a screwdriver as a lever to re-
lease each fi xing clip in turn.

Do not forget to remove the very
cold climate screen when:


- the ambient temperature ex-
ceeds 10 °C,

- towing,

-
driving at speeds above 75 mph
(120 km/h).

Removable protective screen which
prevents the accumulation of snow at
the radiator cooling fan.











FITTING ROOF BARS


For safety reasons and to avoid dam-
aging the roof, it is essential to use the
transverse bars approved for your ve-
hicle.

When fi tting roof bars, use only the four
fi xing points located in the roof frame.
The points are masked by the vehicle
doors when closed.
The roof bar fi xings include a stud to be
fi tted to the hole at each fi xing point.
Observe the fi tting instructions and the
conditions of use in the guide supplied
with the bars.
Maximum authorised weight on
the roof rack, for a loading height
not exceeding 40 cm (with the
exception of bicycle carriers):
80
kg
.
As this value is subject to
change, check the maximum
load fi gure given in the guide
provide d with the roof bars.
If the height exceeds 40 cm,
adapt the speed of the vehicle
to the profi le of the road to avoid
damaging the roof bars and the
fi xings on the vehicle.
Be sure to refer to national leg-
islation in order to comply with
the regulations for transporting
objects which are longer than
the vehicle.

TOWING A TRAILER


We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or installation of a bicycle carrier,
with additional lighting and signalling.

Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer.
Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.



Driving advice


Distribution of loads



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. Above
1 000 metres, the maximum towed load
must be reduced by 10 % for every
1 000 metres of altitude.

Side wind



Take into account the increased
sensitivity to side 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.



To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant temperature.



If 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 on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres




Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.



Lighting



Check the electrical lighting and sig-
nalling on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
