Tire pressure warnings and
messagesThe tire pressure monitoring system warns about
loss in pressure in two stages, depending on the
amount of pressure loss:
Stage 1 – Tyre pressure too low message
(3 to 6 psi (0.2 to 0.4 bar) loss in pressure)
Stage 2 – Flat tyre warning
(loss in pressure as of 6 psi (0.4 bar))
Warning!
Risk of accident. Tire damage may impair
road safety.
fStop the vehicle in a suitable place. Check the
tires for signs of damage and change them if necessary.
Example: If the tyre pressure display shows
„– 3 psi“, you must increase the tyre pressure by
3psi.
Tires lose air over time without a tire defect being
present. The tire pressure monitoring system will
then issue a corresponding message or warning.
