Tyre Pressure Monitoring System; Operating Principle - Renault Megane Driver's Handbook Manual

TYRE PRESSURE MONITORING SYSTEM

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 display 1 and on-
board computer 2 that the tyres are suf-
ficiently inflated and warns if they are
underinflated or leaking. The warning
light 4 on the instrument panel
comes on to warn the driver if the pres-
sure is too low.
This function is an additio-
nal 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.

Resetting the standard level
for the tyre pressures
This should be done:
– when the standard tyre pressure
needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after swapping wheels over (how-
ever this practice is not recom-
mended);
– after changing a wheel.
It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).
With the ignition on:
– Make short presses on the control 3
3
to select the tyre pressure display
(see "On-board computer: settings"
in Section 1);
– press and hold (around 3 seconds)
the button 3 to launch the reset. A
flashing tyre followed by the mes-
sage "Pressure ref Ongoing" indi-
cates that the request to learn the
reference pressure has been taken
into account;
– reset can take several minutes of
driving.
