end of its travel.
F

P
ull on the bonnet to check that it is fully
latched.
The location of the interior bonnet release
lever prevents opening of the bonnet when
the left-hand front door is shut. When the engine is hot, handle the
exterior safety catch and the stay with
care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode.
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.
Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, etc.) be limited.

7. Engine oil dipstick.
8. Engine oil filler cap.
9. Remote earth point.
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

200
If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

I
f the level is above the MAX mark (risk of
damage to the engine), contact a
CITROËN
dealer or a
qualified workshop.
-

I
f the level is below the MIN mark, you must
top up the engine oil.
Oil grade
Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
F

U
nscrew the oil filler cap to access the filler
opening.
F

A
dd oil in small quantities, avoiding any
spills on engine components (risk of fire).
F

W
ait a few minutes before checking the
level again using the dipstick.
F

A
dd more oil if necessary.
F

A
fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
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.
Engine oil change
To ensure that the reading is correct, your
vehicle must be parked on a level sur face
with the engine stopped 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).
Checking using the dipstick
The location of the dipstick is shown in the
corresponding underbonnet layout view.
F
T
ake the dipstick by its coloured grip and
pull it out completely.
F

W
ipe the end of the dipstick using a clean
non-fluffy cloth.
F

R
efit the dipstick and push fully down, then
pull it out again to make the visual check:
the correct level is between marks A and B .A = MA X
B = MIN
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.
Practical information

12 V battery
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in
accordance with regulations and must
not, in any circumstances, be discarded
with household waste.
Take used remote control batteries and
vehicle batteries to a
special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a
well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.
Access to the battery
The battery (-) terminal is not accessible.
A remote earth point is located on the upper
part of the bonnet (next to the battery).
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a
battery booster.
Never try to start the engine by connecting
a
battery charger.
Never use a
24 V or higher battery
b o o s t e r.
Check beforehand that the backup
battery has a
nominal voltage of 12 V and
a
capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, etc.).
Ensure that the jump lead cables do not
pass close to moving parts of the engine
(cooling fan, belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
The battery is located under the bonnet.
For access to the (+) terminal:
F

r

elease the bonnet using the interior lever,
then the exterior safety catch,
F

r

aise the bonnet and secure it with its stay,
F

l

ift the plastic cover for access to the (+)
terminal.

Running out of fuel
(Diesel)
On vehicles fitted with Diesel engines, the fuel
system must be primed if you run out of fuel.
For all versions other than BlueHDi, refer to the
corresponding engine compartment view.For more information on Diesel misfuel
prevention , refer to the corresponding
section.
If the engine does not start first time, do
not keep trying but start the procedure
again from the beginning.

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.
