Tire pre ssure warnings
The Tire Pressure Monitoring warns about loss in
pressure in two stages, depending on the amount
of pressure loss:
Stage 1 - Add air
(3 to 6 psi (0.2 to 0.4 bar) loss in pressure)
Stage 2 - Flat tire
(from 6 psi (0.4 bar) loss in pressure)
Stage 1 - Add air
The pressure in the tire is too low by 3 to 6 psi (0.2
to 0.4 bar). Drivin g with insufficient tire pressure
reduces the road safety of the vehicle and destroys
the tire and wheel.
The tire pressure warning contains the
affected tire with the tire pressure to be
added. Correct the tire pressure at the next
opportunity.
This tire pressure warning appears with vehicle
stopped and can be acknowledged. The tire
pressure warning light in the instrument panel goes
out when the tire pressure has been corrected.
Stage 2 - Flat tire
The pressure in the tire has dropped by more than
6 psi (0.4 bar). This significant pressure loss is a
danger to road safety.
