2021 CITROEN C5 AIRCROSS oil level

192
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.
Cabin filter
Depending on the environment and
the use of the vehicle (e.g. dusty
atmosphere, city driving), change it
twice as often if necessar y .A clogged cabin filter may have an
adverse effect on the per formance of
the air conditioning system 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 necessar y
.
Oil filter
Change the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
or 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.
AdBlue (BlueHDi)
An alert is triggered once the reser ve level is
reached.
For more information on the AdBlue range
indicators , refer to the corresponding section.
To avoid the vehicle being immobilised as per
regulations, you must top up the AdBlue tank.
For more information on the Supply of
AdBlue , 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.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and
offers very specific products.
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 any work on the 12 V batter y,
refer to the corresponding section.
Practical information

193
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 per fectly 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, 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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN
dealer or a
qualified workshop.
Electric parking brake
This system does not require any
routine servicing. However, in case
of an issue, do not hesitate to have
the system checked by a
CITROËN
dealer or a
qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
Wheels and tyres
The pressure must be checked on
all tyres, including the spare wheel,
when the tyres are "cold", at least
once a
month and before a long
j o u r n ey.
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.
