Resetting to public road mode
When race circuit mode is in use, the prompt
“Race circuit mode yes/no” appears after
switching on the ignition on the on-board
computer:
Yes:
Selecting “Yes” retains the set tire pressures for
monitoring when driving on the race circuit.
No :
Selecting “No” resets the tire pressures to be
monitored to public road mode.
Until the current pressures are displayed, “ -,- ”
appears for approx. 2 minutes.
f After changing to public road mode, call
“Pressure info” in the Tire pressure menu
and correct the tire pressures according
to these specifications.
Tire pressure warnings
The tire pressure monitoring system warns about
loss in pressure in two stages, depending on the
amount of pressure loss:
Stage 1 – Tire pressure too low
Stage 2 – Flat tire
Tire pressure monitoring gives a warning about
loss of pressure both in public road mode as well
as in race circuit mode.
Stage 1 – Tire pressure too low
(3 to 6 psi (0.2 to 0.4 bar ) loss in pressure)
The pressure in the tires is too low by 3 to 6 psi
(0.2 to 0.4 bar).
Driving with insufficient tire pressure reduces the
road safety of the vehicle and destroys the tire and
wheel.
f
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.
