IMPREZA U.S.A. (E)
6-20
The display indicates atmospheric pressure in the passenger compart-
ment.
Range : 21.26 to 30.86 inHg or 720 to 1045 hpa
NOTE
D The reading may change during air-conditioner operation, door win-
dow operation, driving in a tunnel, and so forth.
D All barometric readings reported in local weather reports are cor-
rected to a sea-level reading regardless of altitude. The Gauge Pack dis-
plays true local air pressure and hence may differ significantly from local
weather reports (especially at higher altitudes). The barometer is not
adjustable.
D Since air pressure changes with altitude, the barometric reading will
vary when the vehicle is moving up or down an incline. For accurate
barometric trending, the vehicle should be stationary.
J
Altimeter
The altimeter has two modes, Standard elevation mode and Relative
elevation mode.
