Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items at the back of the boot, as
close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use
a roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Obser ve the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-

b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Do not forget the spare wheel and the tyres on
any trailer or caravan.
Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule. When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. Visit a CITROËN dealer or
a

qualified workshop as soon as possible to
bring your vehicle's nitrogen oxides emissions
back in line with regulations.

Malfunction of the SCR
emissions control system
Malfunction detection
If a malfunction is detected,
t hese warning lamps come on,
accompanied by an audible signal
and the display of an "Emissions
fault" message.
The alert is triggered while driving as soon
as the fault is detected for the first time, then
when switching on the ignition for subsequent
journeys, while the fault persists. If it is a
temporary fault, the alert
disappears during the next journey,
after self-diagnostic checks of the SCR
emissions control system.
Malfunction confirmed during the
permitted driving phase (between
685
miles and 0 miles (1,100 km and 0 km))
If the warning lamp is still on after 31 miles
( 50 km) of driving, the fault in the SCR system
is confirmed. Have the system checked by a
CITROËN
dealer or a qualified workshop as soon as
possible.
Starting prevented
Every time the ignition is switched on, the
message "Emissions fault: Starting prevented"
is displayed.
To be able to restart the engine, call
on a
CITROËN dealer or a qualified
workshop.
The AdBlue warning lamp flashes,
accompanied by the display of a
message
("Emissions fault: Starting prevented in x
miles") indicating the remaining range in miles
or kilometres.
While driving, the message is displayed every
30

seconds. The alert is repeated when
switching on the ignition.
You can continue driving for up to 685 miles
(1,100 km) before the engine star ting
prevention system is triggered.

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a
level drops significantly, have the
corresponding system checked by a
CITROËN
dealer or a
qualified workshop.
The fluids must comply with the
manufacturer's requirements and with the
vehicle's engine.

Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close
to the " MAX" mark. If not, check the
brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Engine coolant
Check the engine coolant level
regularly.
It is normal to top up this fluid
between two services. The check and top-up must only be done with
the engine cold.
A low level presents a
risk of serious damage
to the engine.
The level of this fluid should be close to the
" MAX " mark but should never exceed it.
If the level is close to or below the " MIN" mark,
it is essential to top up.
When the engine is hot, the temperature of this
fluid 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 if you need to top
up in an emergency, wrap 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 to the required level.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

Cooling of the engine when stopped
The engine cooling fan may star t after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the
fan!Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
Filling with pure water is prohibited
under all circumstances (risk of freezing,
limestone deposits, jets, etc.).
Diesel fuel additive (Diesel
with particle filter)
or The minimum level in the particle
filter additive tank is indicated by fixed
illumination of this warning lamp,
accompanied by an audible warning
and a
message warning that the level
of additive is too low.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
7
Practical information

193
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
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.
New vehicle
The first particle filter regeneration
operations may be accompanied by a
"burning" smell, which is per fectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
Unless there is a
leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in case
of an issue, do not hesitate to have
the system checked by a
CITROËN
dealer or a
qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have
driven for more than 10
minutes or more
than 6

miles (10 kilometres) at over 31 mph
(50

km/h), add 0.3 bar (30 kPa) to the values
indicated on the label.
