For Canadian models: additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures.
When correcting the tire inflation pressures,
note the following:
The tire pressure increases as the tire temper‐
ature increases.
Therefore, only correct the tire inflation pres‐
sure when the tire is at the ambient temperature.
Compare the displayed tire temperature with
the external temperature in the instrument clus‐
ter.
Resetting the system
