Warning and indicator
lamps
Displayed as symbols, visual indicators
which inform the driver of the occurrence of a
malfunction (warning lamps) or of the operation
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 illumination to the
operating status of the vehicle can determine
whether the situation is normal or 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.
Persistent warning lamp
When the engine is running or the vehicle is
being driven, the illumination of a red or orange
warning lamp indicates a fault that needs
further investigation, using any associated
message and the description of the warning
lamp in the documentation.
Where a warning lamp remains lit
The references (1) , (2) and (3) in the warning
lamp description indicate whether you should
contact a qualified professional in addition to
the immediate recommended actions.
(1 ) : You must stop as soon as it is safe to
do so and switch off the ignition.
(2): Contact a CITROËN dealer or a qualified
workshop.
(3) : Go to a CITROËN dealer or a qualified
workshop.

Engine oil level indicator
(depending on version)
On versions fitted with an electric oil level
indicator, the state of the engine oil level is
displayed in the instrument panel for a few
seconds, after the servicing information.
The level read will only be correct if the
vehicle is on level ground and the engine
has been off for more than 30 minutes.
Oil level correct
Oil level incorrect
This is indicated by the display of a message
in the instrument panel screen, accompanied
by the Ser vice warning lamp and an audible
signal.
If the low oil level is confirmed by a check using
the dipstick, the level must be topped up to
avoid damage to the engine.For more information on Checking levels ,
refer to the corresponding section.
Oil level indicator fault
This is indicated by a message in the
instrument panel.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a fault with the electric indicator,
the oil level is no longer monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located under the bonnet.
For more information on Checking levels ,
refer to the corresponding section.Retrieving the service
information
You can access the ser vice information at any
time in the touch screen.
AdBlue® range indicators
These range indicators are present only on
BlueHDi Diesel versions.
Once the AdBlue
® tank is on reser ve or after
detection of a fault with the SCR emissions
control system, when the ignition is switched

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 fluid 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 on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.
Practical information

145
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).

AdBlue level
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 it up, refer to
the corresponding section.
Checks
Unless otherwise 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.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(versions without quick release
terminals) and that the connections
are clean.
For more information on the precautions
to take before starting work on the
12 V batter y , refer to the corresponding
section. Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.
Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often, if
necessary
.
Passenger compartment
filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it 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.
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 indicated by the constant
illumination of this warning lamp
accompanied by an alert message.

Practical information

148
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 the
levels and particularly on the level of
Diesel additive, 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.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electronic 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/drum wear
For 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.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units
as important as those in the braking
system, CITROËN selects and offers very
specific products.
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.
