four wheel drive Citroen JUMPY RHD 2016 2.G Owner's Manual

Under-inflation detection
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
Tyre pressures should be checked
when the tyres are "cold" (vehicle
stopped for 1 hour or after a journey of
less than 6 miles (10 km) at moderate
speeds).
Other wise (when hot), add 0.3 bar to
the pressures shown on the label.
Driving with under-inflated tyres
increases fuel consumption.
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.

Under-inflation alertReinitialisation
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation alert can only
be relied on if the reinitialisation of
the system has been done with the
pressures in the four tyres correctly
adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and, depending on
equipment, the display of a message.
It is necessary to reinitialise the system every
time one or more tyre pressures are adjusted,
and after changing one or more wheels.

f it is not possible to make this check
immediately, drive carefully at reduced
speed.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check. The alert is maintained until the system
is reinitialised.
Initialisation of the system is done with the
ignition on and the vehicle stationary.The new pressure settings registered
are considered to be reference values
by the system.

recommendations
Observe the legislation in force in your
c o unt r y.
Ensure that the weight of the towing
vehicle is higher than that of the towed
vehicle.
The driver must remain at the wheel of
the towed vehicle and must have a valid
driving licence.
When towing a vehicle with all four
wheels on the ground, always use an
approved towing arm; rope and straps
are prohibited.
The towing vehicle must move off gently.
When towing a vehicle with the engine
off, there is no longer any power
assistance for braking or steering.
In the following cases, you must always
call on a professional recovery service:
-
