SEALION 7 tyre-pressure warning: what to check

Use the SEALION 7 pressure label. The tyre sidewall maximum is not the vehicle’s operating setting, and the correct value depends on the fitted wheel and tyre combination.

Check all four tyres

  1. Park safely and let the tyres cool.
  2. Read the required cold pressures from the vehicle label or exact owner manual.
  3. Measure every tyre with the same dependable gauge and adjust only to the stated cold values.
  4. Inspect tread, sidewalls, valves and wheels for a nail, cut, bulge, cracking or impact damage.
  5. Power the car on and note whether it shows one low value, a missing value or a general system warning.
  6. Drive only as the manual requires for readings to update, then stop and compare again.

Interpret the result

  • One tyre falls again: arrange a professional leak check rather than repeatedly inflating it.
  • Pressure is correct but one reading is absent: the sensor or monitoring system may need diagnosis.
  • Several readings changed in colder weather: correct them cold and continue monitoring.
  • Vibration or unstable handling is present: stop and inspect rather than relying only on the display.

A bulge, exposed cord, severe cut, rapidly falling pressure or damaged wheel means the car should remain stopped for tyre service or recovery.
