Observe 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.
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 oxide emissions
back in line with the regulations.
When filling the tank, do not continue after the
3rd 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.
At the end of winter, remove snow tyres and
refit your summer tyres. 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.
.
Eco-driving

142
Have it checked by a CITROËN dealer or
a qualified workshop.
If a
fault occurs in STOP mode, the engine may
stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N and press the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
The Stop & Start requires the use of
a 12 V battery of special specification and
technology.
All work on this type of battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
For more information on the 12
V batter y,
refer to the corresponding section.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
the risk of injury related to an automatic
change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Tyre under-inflation
detection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure of the four
tyres when the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres. The under-inflation detection system does
not replace the need for vigilance on the
part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a


long journey.
Driving with under-inflated tyres worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section.

10. Priming pump*
The Diesel fuel system operates under
very high pressure.
All work on this circuit must be carried out
only by a
CITROËN dealer or a qualified
workshop.
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 liquid 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 in using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.

Practical information

201
Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up. To avoid the risk of scalding when 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.
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
This fluid must conform to the manufacturer's
recommendations.
Screenwash/headlamp
wash level low
In the case of vehicles fitted with
headlamp washers, when the fluid
reser voir low level is reached this
warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a


message.
The warning lamp comes on when the ignition
is switched on, or every time the stalk is
operated, until the reser voir is refilled.
The next time you stop, have the screenwash/
headlamp wash reser voir topped up.
Diesel fuel additive level
(Diesel with particle filter)
The additive reser voir low 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.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and, in particular, topping up the tank,
refer to the corresponding section.
When the engine is hot, 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.

Practical information

203
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.
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
specific check. However, in the
event of a problem, 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 given 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 more than 31 mph (50 km/h),
0.3 bar (30 kPa) should be added to the values
given on the label.
Under-inflation increases fuel consumption.
Non-compliant tyre pressure causes premature
wear on tyres and has an adverse effect on the
vehicle's road holding – Risk of an accident!
Driving with worn or damaged tyres reduces
braking efficiency and control of the vehicle's
steering. Regular inspections of the condition
of tyres (tread and sides) and rims are
recommended as well as making sure that
valves are fitted.
Using different size wheels and tyres from
those specified can affect the lifetime of tyres,
wheel rotation, ground clearance and the
speedometer reading and have an adverse
effect on road holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.

Identification markings
Different visible markings for the identification
and research of your vehicle.
A. Vehicle Identification Number (VIN),
under the bonnet.
This number is engraved on the chassis near
the right-hand front wheel arch.
B. Vehicle Identification Number (VIN), on
the windscreen lower cross member.
The number is on a label, visible through the
windscreen. -
the European Whole Vehicle Type Approval number,
-
t he Vehicle Identification Number (VIN),
-

t
he maximum authorised weight (gross vehicle
weight),
-

t
he maximum authorised weight with trailer (gross
train weight),
-

t
he maximum weight on the front axle,
-

t
he maximum weight on the rear axle.
D. Tyre/paint label.
This label on the middle door pillar, driver's
side, contains the following information:
-
t
he tyre inflation pressures with and without
load,
-

t
he tyre sizes (including the load index and
speed rating),
-

t
he spare tyre inflation pressure,
-

t
he paint colour code. The vehicle may be originally equipped
with tyres with higher load and speed
indices than those indicated on the label,
without affecting inflation pressure.
C. Manufacturer's label.
This tamperproof label on the middle door
pillar, right or left-hand side, contains the
following information:
-

t

he name of the manufacturer, Checking tyre pressures
The tyre pressures should be checked when
cold at least monthly.
The pressures given on the label are valid for
cold tyres. If you have driven for more than
10
minutes or more than 6 miles (10 kilometres)
at more than 31 mph (50 km/h), the tyres will be
warm; in this case 0.3 bar (30 kPa) should be
added to the pressures given on the label.
Never reduce the pressure of a warm tyre.
Low tyre pressures increase fuel
consumption.
