2021 CITROEN C4 AIRCROSS spare wheel

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...). Use a roof box in preference.
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.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter...) and
observe the schedule of operations recommended by the manufacturer.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
Under-inflation detection
System which continuously and automatically checks the pressures of the four tyres after switching on the ignition.
A pressure sensor is located in the valve of each tyre (except the spare wheel).
The system triggers an alert if a drop in pressure is detected in one or more tyres, compared to the reference pressure registered in the system.
This reference pressure must be reinitialised every time the tyre pressures are adjusted or a wheel changed.
The system operates on condition that sensor identifiers have first been memorised in the system by a CITROËN dealer or a qualified workshop.
You can memorise two sets of tyres (for example: wheels with "standard" tyres and wheels with "winter" tyres).
Driving with under-inflated tyres
increases fuel consumption.This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.

top as soon as it is safe to do so. The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check. The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.
The spare wheel does not have
a sensor, so there is no need to
reinitialise the the system for running
with the spare wheel fitted.

temporary puncture repair kit for example),

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment).
Reinitialising the reference
pressure
Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The system must be reinitialised after any
adjustment of tyre pressures and after
changing one or more wheels.

The reinitialisation instruction is entered in
the screen menu, with the ignition on and the
vehicle stationary.
F Press repeatedly on the INFO button
to select "REINITIALISE" (located in
menu
2/3 or 3/3 depending on the
instrument panel) .
F

P
ress and hold the INFO button for at least
3 seconds to reinitialise the under-inflation
detection system.
Reinitialisation of the system is confirmed
by the flashing of the warning lamp in the
instrument panel. The under-inflation alert is only reliable
if the system has been reinitialised
with the four tyre pressures correctly
adjusted.
Operating fault
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied by
the display of a message indicates a fault with
the system.
In this case, monitoring of the tyre pressures is
not assured.
This alert is also displayed if:
-

o
ne or more wheels is not fitted with a
sensor (spare wheel in use),
-

a w
ireless device operating on the same
frequency is close to the vehicle,
-

t
here are accumulations of snow or ice in
the wings or wheels,
-

t
he state of charge of the tyre pressure
monitoring system battery is too low,
-

t
he wheel sensor identifiers have not been
memorised in the system by a CITROËN
dealer or a qualified workshop. Any tyre repair or replacement on a
wheel fitted with this system must be
carried out by a CITROËN dealer or a
qualified workshop.
If you fit the second set of tyres
memorised in the system, a fault will
be signalled until the second set is
selected in the configuration menu. Go to a CITROËN dealer or a qualified
workshop
to have the system checked
or, following the repair of a puncture, to
have the original wheel, equipped with a
sensor, refitted.

The spare wheel is installed in the boot under
the floor.
Depending on version, the spare wheel may be
a standard size steel or alloy wheel, or for some
countries it is the "space saver" type.
For access to the spare wheel, see "

Fitting a wheel
After changing a wheel
When using the "space-saver" spare
wheel, do not exceed a speed of
50 mph (80 km/h).
Have the tightening of the bolts and the
pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.
Have the punctured wheel repaired and
replace it on the vehicle as soon as
possible.

Fitting snow tyres
If you equip your vehicle with snow
tyres fitted on steel wheel rims, special
bolts available from your CITROËN
dealer or a qualified workshop must
be used.
If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.
