ENG_NU_939-3_D91_Renault_2
This system monitors the tyre pressure.
Information is displayed:
– with the ignition on, when scrolling
through the trip computer and warn-
ing system information by pressing
control 2 (refer to the information
on the “trip computer and warning
system” in Section 1);
– or if there is a fault when driving
(refer to the following page to find out
more about the warning messages).
Tyre pressure monitor
This function is an addi -
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig -
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
tyRe PReSSURe MoNItoR (1/3)
If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure.
The system informs the driver via the
trip computer and warning system 1
that the tyres are sufficiently inflated
and warns if they are underinflated or
leaking.
t he tyre pressure can be adjusted
when cold (refer to the information on
“Tyre pressures”).
If tyre pressures cannot be checked
when the tyres are cold, the recom -
mended pressures must be increased
by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.1

Changing a wheel
The system may take sev -
eral minutes depending on
use for the new wheel po -
sitions and pressures to be recog -
nised; check the tyre pressures after
all operations.

(flat tyre, punctured tyre, system fault,
etc.).

“Check tyre pressure”
A shaded wheel B indicates a deflated
tyre.
“Inflate tyres to motorway pressure”
The tyre pressure is not suitable for the
speed of travel. Slow down or inflate all
four tyres to motorway pressure (refer
to the information on “Tyre pressures”).
“Puncture”
Wheel B indicates that the tyre con -
cerned is punctured or severely un -
derinflated. Replace it or contact an
approved dealer if it is punctured. Top
up the tyre pressure if the wheel is de-
flated.
This message appears along with the
® warning light.
“t
yre sensors absent” or “check
tyre sensors”
One wheel A disappears, indicating
that the sensor on this wheel is missing
or faulty (e.g. if the emergency spare
wheel is fitted).

Interchangeability of wheelsIf you wish to swap the wheels around,
please consult an approved dealer to
reinitialise the system.
emergency spare wheelIf the vehicle is equipped with an emer-
gency spare wheel, it will not have a
sensor. When it is fitted to the vehicle,
the message “tyre sensors absent” is
displayed on the instrument panel.
Replacing wheels/tyres
This system requires specific equip -
ment (wheels, tyres, hubcaps, etc.).
Contact an approved dealer to fit new
tyres and to find out about accessories
compatible with the system and avail -
able from manufacturer ’s accessory
outlets: the use of any other accessory
could affect the correct operation of the
system or damage the system.
t yre repair products
Because the valves are specially de -
signed, only use products approved by
our Technical Department.
tyRe PReSSURe MoNItoR (3/3)
Each of the sensors incorporated in the valves 3 is dedicated to a single
wheel: under no circumstances should you swap the wheels, without re-
setting the system.
There is a risk of incorrect information which could have serious conse-
quences.
