Towing a trailer
We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to 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.
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
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving
advice
, particularly when towing, refer
to the corresponding section.
For more information on Weights (and
the towed loads which apply to your
vehicle) refer to the corresponding
section.
You must observe the maximum trailer
weight, indicated on the registration
certificate or in the technical
specification for your vehicle. When not towing a trailer, remove the
quickly-detachable tow ball before
driving.
The lane departure warning system is
deactivated while a trailer is connected.

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

corresponding underbonnet layout view.

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

for more than 30 minutes. A = MA X

Checks
12 V battery
The battery does not require any
maintenance.
However, check that the terminals
are clean and correctly tightened,
particularly in summer and winter.Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filterThe presence of this label, in particular
with the Stop & Start system, indicates
the use of a specific 12 V lead-acid
battery with special technology and
specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle
(e.g. city driving), replace them twice as often
if necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the fixed
illumination of this warning lamp
accompanied by a warning message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels and the Diesel additive level in
particular, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
When carrying out work on the battery, refer
to the "
12 V batter y " section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.

AdBlue® additive and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
SCR system
Using a fluid called AdBlue® containing
urea, a

catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. The AdBlue
® is held in a special tank with a
capacity of about 17 litres: this provides a driving
range of about 12 500 miles (20 000 km). An
alert is triggered automatically to warn you when
the reserve level is reached: you can then drive
about 1 500 miles (2 400 km) before the tank is
e m pt y.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12 500 miles (20 000 km), it will be necessary
to top-up the AdBlue
®. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1

100 km), a system will be triggered
automatically to prevent engine starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.
