Monitoring
When the engine is
running, this indicates the
temperature of the coolant.






Range


When the engine is
running
, this indicates
the distance which can
still be travelled with the
fuel remaining in the tank
based on the average
fuel consumption over the
last few miles/kilometres
travelled.
This value may vary following a change
in the style of driving or the relief,
resulting in a large variation in the
current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,
you must fill the tank whenever
possible.










Coolant temperature
gauge
If the bar is close to the critical
position located
on the right, the temperature is too high.
The symbol flashes when your engine is
overheating.


You must stop your vehicle as soon as it is
safe to do so.


Wait a few minutes before switching off the
engine.

When the range is less than 30 miles (50 km)
,
dashes are displayed.
Refuel as soon as possible. The display of the
range is updated.

Wait for the engine to cool before
topping up the level. The cooling system
is pressurised.
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,
if necessary.
Contact a CITROËN dealer or a
qualified workshop.

When you disconnect the battery,
the previous fuel consumption data
is lost and the value displayed will be
different from that displayed before the
battery was disconnected. The distance
displayed must be considered an
approximate indication.

Comfort








Vent ilat i on


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:


- 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 grouped
together on control panel A
on the centre
console.

1.
Windscreen demisting-defrosting vents.

2.
Front side window demisting-defrosting
vents.

Automatic operation



)
Set the temperature control dial 1
to the
temperature required.

)
Place the air flow control dial 2
in
the "AUTO "
position.

)
Place the air distribution adjustment dial 3

in the "AUTO "
position.
When the engine is cold, to avoid an
excessive distribution of cold air, the
ventilation will reach its optimum level
gradually.
On entering the vehicle, the interior
temperature may be much colder
(or warmer) than the temperature
setting. There is no need to change the
temperature setting in order to reach
the comfort required rapidly.
The automatic regulation of the air
conditioning will operate to correct the
temperature difference as quickly as
possible.
In automatic mode:


)
when the temperature is set to maximum
(Rapid heating), the intake of exterior air is
activated and the air conditioning stops.

)
when the temperature is set to minimum
(Rapid cooling), air recirculation is
activated and the air conditioning operates.
The system controls the air distribution, the
flow, the temperature and the air intake to
ensure the level of comfort selected and
adequate air circulation in the passenger
compartment. No further action on your part is
required.

208Practical information

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 per formance. Above
1 000 metres, the maximum towing load must
be reduced by 10 % of the GTW and so on for
every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towing loads which apply to
your vehicle.


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 towing load on a long slope
depends on the gradient and the outside
temperature.
In all cases, pay attention to the coolant
temperature.


)
If this message is displayed, stop your
vehicle as soon as it is safe to do so.




Braking

Towing a trailer increases the braking distance.


Ty r e s



)
Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the
recommended pressures.



Lighting



)
Check the lighting and signalling on the
trailer.


If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.

Checks






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).


















Oil level


The check of the the level is done
out with the dipstick, located under
the bonnet. Refer to the description
of your engine compartment for the
position of the dipstick.
Engine oil change

Refer to the maintenance and warranty guide
for details of the inter val 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's
recommendations.

Check all of these levels regularly, 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 the level is above this
mark, contact a CITROËN
dealer or a qualified
workshop.

B
= minimum
Top up the level through the
oil filler orifice, using the
correct grade of oil for your
engine. The level must never
be below this mark.
This check 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 between
two ser vices (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 km).
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.

Checks










Coolant level


The coolant level should be between
the two marks. 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
manufacturer's recommendations.
The 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 guide
for details of the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to the
manufacturer'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.
