TYRE PRESSURE APPROPRIATE FOR SPEED
NOTESBefore carrying out any operation, apply the fault finding procedure (see 35B
Introduction).
NO: If the vehicle speed is above 102 mph (170 km/h) (as an indication) for more than
3 minutes and the pressure on at least one of the tyres is 400 mbar or more below
"motorway" pressure.
YES: if the vehicle speed is below 102 mph (170 km/h) (as an indication) or if the
pressure of the four tyres corresponds to the pressure of parameters PR011 and
PR012 High speed recommended pressure, whatever the speed.
Make sure that the tyre pressures are at the recommended "motorway" pressure (see MR 370, 35A or Driver's
Handbook), and reinflate the tyres if necessary.
Check that the pressures entered (PR009 to PR012) match the manufacturer's specifications.
If the pressures entered do not correspond to the manufacturer's values, write the recommended pressures
using procedure VP005 "Write recommended pressures (see Configuration and programming.
If status ET037 remains NO, contact the Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESNone.
Is the tyre punctured?
NO
Check the pressure in all four tyres with a
pressure gauge (fault: severely under-inflated).
NO
Is the pressure correct?
YES
Read the recommended pressures in the UCH
(PR009 to PR012)
Do the values of these parameters match the
manufacturer's recommended pressures?
NO YES
Write the recommended
pressures with command VP005

Repair the tyre
Make sure the valve seal is not damaged.
Make sure the sealing nut on the sensor is one for
valves installed on the Mégane II or Scénic II,
and not one for a Laguna II, Vel Satis or
Espace IV.
After all these checks, if the message still appears
on the instrument panel, contact your Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
