Is the tyre punctured?Repair the tyre.
Check the pressure in all 4 tyres with a
pressure gauge (problem: severe under-
inflation).
Is the pressure correct?
Make sure the valve seal is not damaged.
Check that the sealing nut on the valve is one for
valves installed on the Mégane II or Scénic II, and
not one for a Laguna II, Vel Satis or Espace IV. Read the recommended pressures in the UCH
(PR009 to PR012).
Do the values of these parameters match
the manufacturer's recommended
pressures?
After all these checks, if the message still appears
