Towing device
Load distribution
F D istribute 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. The maximum
load which can be towed must be reduced by
10% per 1,000
metres of altitude.
Use towing devices and their genuine
harnesses approved by CITROËN. It is
recommended that the installation be
per formed by a CITROËN dealer or a
qualified workshop.
If the towbar is not fitted by a CITROËN
dealer, it must still be fitted in accordance
with the vehicle manufacturer's
instructions.
Certain driving assistance or manoeuvring
assistance functions are automatically
disabled if an approved towbar is used.

Practical information

172
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still use
functions such as the audio and telematics
system, windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about forty
minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched
to economy mode and the active functions are
put on standby.
If a telephone call is being made at this
time, it will be maintained for around
10
minutes with the hands-free kit of your
audio system.

Checking levels
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. The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine. 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).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop and dispose of
it in the containers reser ved for this
purpose.
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. 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.
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).

Practical information

178
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 the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up the coolant.The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
A low coolant level presents a risk of serious
damage to your engine.
Top up the fluid when necessary.Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel fuel additive level
(Diesel with particle filter)
The additive tank minimum level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
