2021 CITROEN C4 CACTUS oil filter

Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items in the bottom 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.
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 oxides emissions
back in line with the regulations.
When refuelling, do not continue after the 3
rd
cut-off of the nozzle to avoid any 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.

Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, etc.) be limited.
Engines
Petrol
Diesel
These engines are examples provided as a
guide.
The locations of the following elements may
vary:
-
A
ir filter.
-

E
ngine oil dipstick.
-

E
ngine oil filler cap. 1.
Screenwash fluid reservoir.
2. Engine coolant reservoir.
3. Brake fluid reser voir.
4. Battery.
5. Fusebox.
6. A i r f i l t e r.
7. Engine oil dipstick.
8. Engine oil filler cap.
9. Remote earth point.
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 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

147
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.
7
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.
