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).

239Checks






Checking levels


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.


















Oil level

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.












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.
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

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

Coolant level


The coolant level should be close
to the "MA X" 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 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.












Power steering fluid level

The power steering fluid level should
be close to the "MA X" mark. With
the engine cold, unscrew the cap to
check the level. To check the level or top up the
fluid on vehicle fitted with headlamp
washers, immobilise the vehicle and
switch of the engine.

Screenwash / headlamp
wash fluid level







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.

279Practical information








Changing a wiper blade


Before removing a front
wiper blade



Within one minute after switching off
the ignition, operate the wiper stalk to
position the wiper blades vertically on the
windscreen.



Removing




Raise the corresponding wiper arm.


Unclip the wiper blade and remove it.



Fitting




Put the corresponding new wiper blade in
place and clip it.


Fold down the wiper arm carefully.



After fitting a front wiper
blade



Switch on the ignition.

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 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 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 STOP

warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.

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



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.


Ty r e s



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



Lighting




Check the electrical lighting and signalling
on the trailer.

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