stop start CITROEN C5 X 2022 Service Manual

160
Practical information
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.
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
battery, 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.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city 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.
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 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 the event of a
problem, 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 inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
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.
Under-inflation increases energy
consumption. Non-compliant tyre

168
In the event of a breakdown

► Switch on the compressor by moving the
switch to position " I
" until the tyre pressure
reaches 2 bar. The sealant product is injected
under pressure into the tyre; do not disconnect
the pipe from the valve during this operation (risk
of blowback).
If after approximately 7 minutes, the
pressure of 2 bar is not reached, this
indicates that the tyre is not repairable;
contact a CITROËN dealer or a qualified
workshop for assistance.
►

Move the switch to position " O

".
►

Disconnect the compressor's electric plug
from the vehicle's 12

V socket.
►

Remove the kit.
►


Refit the cap on the valve.
►


Remove and store the bottle of sealant.
The sealant product is harmful if swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle into the
environment; 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.


► Drive immediately for approximately 3 miles
(5 kilometres) at reduced speed (between
12 and 37 mph (20 and 60
km/h)) to plug the
puncture.
►

Stop to check the repair
and the tyre
pressure using the kit.
With a tyre repaired using this type of kit,
do not exceed a speed of 50
mph
(80

km/h) and do not drive more than
125

miles (200 km).
Contact a CITROËN dealer or a qualified
workshop to have the tyre changed.
Checking/adjusting tyre
pressures
The compressor can be used, without injecting
sealant, to check and, if necessary, adjust the
tyre pressures.
►

Remove the valve cap from the tyre and keep
it in a clean place.
►


Uncoil
the pipe stowed under the compressor.
►

Screw the pipe onto the valve and tighten
firmly

.
►

Check that the compressor switch is in
position " O

".
►

Fully uncoil the electric cable stowed under
the compressor

.
►

Connect the compressor's electric plug to the
vehicle's 12

V socket.
►

Switch the ignition on.
►


Start the compressor by placing the switch at
position " I

" and adjust the pressure to the value
shown on the vehicle's tyre pressure label. To
deflate: press the black button located on the
compressor pipe, near the valve connection.
If after 7 minutes the pressure of 2 bar is
not reached, the tyre is damaged;
contact a CITROËN dealer or a qualified
workshop for assistance.
►

Once the correct pressure is reached, put the
switch in position " O

".
►

Remove the kit and stow it.
►


Refit the cap on the valve.

In the event of a breakdown
8Contact a CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself, use only a charger compatible with
lead-acid batteries with a nominal voltage of
12

V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
►

Switch the ignition off.
►


Switch off all electrical consumers (audio
system, lighting, wipers, etc.).


► Switch off charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
►

Ensure that the charger cables are in good
condition.
► Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►

Connect the cables of charger B

as follows:
•

the positive (+) red cable to the (+) terminal
of battery

A,
•

the negative (-) black cable to earth point C


on the vehicle.
►

At the end of the charging operation, switch
off charger B

before disconnecting the cables
from battery A.
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components
connected to the Stop & Start system.
24V
12V
Disconnecting/reconnecting the
battery
In order to maintain an adequate state of
charge for starting the engine, we recommend
disconnecting the battery if the vehicle is to be
unused for an extended period.
Before disconnecting the battery:
►

Close all openings (doors, boot, windows,
roof). ►


Switch off all electricity-consuming devices
(audio system, wipers, lamps, etc.).
►

Switch off the ignition and wait for 4
minutes.
After accessing the battery, it is only necessary
to disconnect the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal


► Depending on equipment, lift the plastic cover
on the (+) terminal.
►

Raise lever

A
fully to release clamp
B
.
►

Remove clamp

B
by lifting it off.

176
In the event of a breakdown
Reconnecting the (+) terminal

► Raise lever A fully.
► Refit the open clamp B on the (+) terminal.
►

Push clamp
B fully down.
►

Lower lever

A
to lock clamp B.
►

Depending on equipment, lower the plastic
cover on the

(+) terminal.
Do not force the lever, as it will not lock
in place if the clamp is not positioned
correctly; start the procedure again.
The Stop & Start system may not be operational during the trip following the
first engine start.
In this case, the system will only be available
again after a continuous period with the
vehicle immobilised, the duration of which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
With rechargeable hybrid
engine
The rechargeable hybrid system has two accessory batteries: one at the front and one at
the centre of the vehicle.
Replacing the accessory batteries
Contact a CITROËN dealer or a qualified
workshop.
Jump-starting another vehicle
Do not start or jump start another vehicle
from the vehicle’s accessory batteries.
Accessing the accessory batteries
Front
The front battery is located under the bonnet.

For access to the (+) terminal:
► Release the bonnet by pulling the internal
release lever
, then the external safety catch.
►

Raise the bonnet. (+)

Positive terminal with a quick-release
terminal.

As the battery's negative terminal is not
accessible, a remote earth point is located near
the battery.
Central
The central battery is located in the front armrest
storage compartment.
To reach the battery:




► Open the front armrest.
► Unclip the compartment's floor .
(+) Positive terminal, protected by a red plastic
cover (not accessible).
