Under-inflation detection
System which automatically checks the pressures of the tyres while driving.
T he under-inflation detection system
d
oes not replace the need for vigilance
o
n the part of the driver.
This
system does not avoid the need to
c
heck the tyre pressures (including the
s
pare wheel) every month as well as
b
efore a long journey.
Driving
with under-inflated tyres
i
mpairs road holding, extends braking
d
istances and causes premature
t
yre wear, particularly under arduous
condition
(high loading, high speed,
lon
g
jo
urney).The inflation pressures defined for
your vehicle can be found on the tyre
pressure
label.
See
the "Identification markings"
s
ection.
Tyre
pressures should be checked
w
hen the tyres are "cold" (vehicle
s
topped for 1 hour or after a journey of
l
ess than 6 miles (10 km) at moderate
s
peeds).
Other wise
(when hot), add 0.3 bar to
t
he pressures shown on the label.
Driving
with under-inflated tyres
i
ncreases fuel consumption.
The
system monitors the pressures in the four
t
yres, once the vehicle is moving.
It
compares the information given by the four
w
heel 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
d
etects a drop in the inflation pressure of one
or
more tyres.

The alert is maintained until the system is r einitialised.
The loss of pressure detected does not
always
cause
visible
bulging
of
the
tyre.
D
o
not
satisfy
yourself
with
just
a
visual
c
heck. Before
reinitialising the system, ensure
t
hat the pressures of the four tyres are
correct for the use of the vehicle, as
given
on the tyre pressure label.
The
under-inflation detection system
d
oes not give a warning if a pressure is
i
ncorrect at the time of reinitialisation.
Under-inflation alert
This is given by fixed illumination of this warning lamp, accompanied by
a
n audible signal and the display of a

essage.

I
n the event of a puncture, use the
temporary
puncture repair kit or the spare
w
heel (depending on equipment).
Reinitialisation
It is necessary to reinitialise the system every time one or more tyre pressure is adjusted, and
a
fter changing one or more wheels.
A
label on the middle pillar, left hand side, gives
a
reminder of this.

Towing the vehicleProcedure for having your vehicle towed or for towing another vehicle using a removable towing eye.
T he towing eye is installed in the boot under
t
he floor.
To
gain access to it:
F
o
pen the boot,
F
r
aise the floor,
F
r
emove the polystyrene storage box,
F
r
emove the towing eye from the holder.

neral recommendations
Observe the legislation in force in your country.
E nsure 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
a
rm; 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
b
raking or steering.
In
the following cases, you must always call on a professional recovery service:
-
v
ehicle broken down on a motor way or fast road,
-
f
our-wheel drive vehicle,
-
w
hen it is not possible to put the gearbox into neutral, unlock the steering, or release
t
he parking brake,
-
t
owing with only two wheels on the ground,
-
w
here there is no approved towing arm available...
