Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.
For more information on a system or a function,
refer to the corresponding section.

Practical information
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and
pull it out completely.
► Wipe the end of the dipstick using a clean,
lint-free cloth.


► Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the
support slot.
►

Clip the stay in its housing.
►


Lower the bonnet and release it near the end
of its travel.
►


Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

All work on this circuit must be carried out
only by a CITROËN dealer or a qualified
workshop.
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.
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 and
very corrosive.

101
Practical information
7Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A
(max)
and B (min).
Do not start the engine if the level is:
–

above mark
A: contact a CITROËN dealer or a
qualified workshop.
–

below mark B

: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your CITROËN dealer and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
► Wait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
Within 30 minutes of adding oil, the oil
level indication 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.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
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.

Practical information
7city driving), change it twice as often, if
necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of saturation of the particle filter
is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60
km/h) until the warning lamp
goes off.
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 perfectly 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, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc/drum wear
For any information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is noticed, the
parking brake must be checked, even between
two services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The pressure must be checked on all tyres, including the spare wheel, when the
tyres are "cold".
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.
Driving with under-inflated tyres
increases fuel consumption. Non-
compliant tyre pressure causes premature
wear on tyres and has an adverse effect on
