the operating conditions of the following functions:
● Route guidance display of the navigation system-linked system ( if equipped)
● Incoming call display of the hands-free phone system
The pop-up display function can be disabled.
■ Tire inflation pressure
●It may take a few minutes to display the tire inflation pressur e after the
engine switch is turned to IGNITION ON mode. It may also take a few min-
utes to display the tire inflation pressure after inflation pre ssure has been
adjusted.
● “---” may be displayed if the tire information cannot be determined due to
unfavorable radio wave conditions.
● Tire inflation pressure changes with temperature. The displayed values may
also be different from the values measured using a tire pressur e gauge.
■ Outside temperature display
In the following situations, the correct outside temperature ma y not be dis-
played, or the display may take longer than normal to change:
● When the vehicle is stopped, or moving at low speeds (less than 12 mph [20

• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
● Some pedestrians such as the following may not be detected by t he radar
