2021 CITROEN C4 CACTUS checking oil

21
F In the Driving/Vehicle menu,
select the " Driving functions "
tab, then " Diagnostics ".
The ser vicing information is displayed in the
screen.
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
on, an indicator displays an estimate of the
distance that can be covered, the range, before
engine starting is prevented.

Instruments

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

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

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).
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
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
In order to maintain the reliability of the engine
and emissions control system, never use
additives in the engine oil.

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.
Practical information

After about 7 minutes, if a pressure of
2 bars is not reached, this indicates
that the tyre is not repairable; contact a
CITROËN dealer or a qualified workshop
for assistance.

After use, do not discard the bottle by the
roadside, take it to a CITROËN dealer or
an authorised waste disposal site.
Do not forget to obtain a new bottle of
sealant, available from a CITROËN dealer
or a qualified workshop. Do not exceed the speed of 50 mph
(80
km/h) when driving with a tyre
repaired using this type of kit.
