2.3.3. Display of a conclusion of compass readings and sensor of temperature of external air
|
|
The display is located on the ceiling console of the car and allows to define the direction of the movement of the vehicle concerning the countries of light. Besides indications of the sensor of temperature of external air and the warning of possible frosting of a paving are output to the display. |
For a conclusion of indications of the sensor of temperature it is necessary to press the button on the display control panel at the ignition key turned in situation by ON or ASS. The main measuring scale is served by the Fahrenheit scale, - for transition to a scale of Celsius it is necessary to press the switch button once again. At decrease in temperature below freezing of the display the inscription ICE warning the driver about danger of possible frosting of a roadbed is displayed.

Limit borders of range of measurement are temperature of -20 °F (-30 °C) and 158 °F (70 °C) — at an exit out of limits of the specified range of the display instead of digital value the line from signs of an underlining / dash will be displayed (_ _ _) — it is not necessary to perceive this situation as a sign of failure of the measuring equipment. At a temperature of external air from 130 °F (55 °C) to 158 °F (70 °C) of the display value 130 °F (55 °C) will be displayed. |
The sensor of temperature of external air is located before a radiator and can perceive heat radiated by the engine and a paving, besides, the direction and speed of the running air stream, and also a number of other factors exerts impact on indications of the sensor. Told means that the indications output to the display should be considered only as approximate (including the warning of a possibility of frosting of a paving), do not forget to listen to regional road news regularly.
Conclusion to the screen of the display of indications of a magnetic compass is made by pressing of the same button control panels — the ignition key has to be turned in position of ON or ASSORTMENT. The difference between the direction on magnetic and geographical northern poles is called inducement. At the same time the size of inducement depends on the longitude with which measurement is performed.
The card of zones of magnetic inducement (For North America)
In case of need definitions of the exact direction to the geographical North Pole follow the following instructions.
|
|
- Determine a zone of your location by the special card (see the illustration Card of Zones of Magnetic Inducement (For North America)), write down result.
|
- Holding the ON/OFF button on the control panel of the display pressed within about 5 seconds wait for a conclusion to the screen of value of number of a zone — in case of need pressing the same button make the corresponding adjustment.
|
|
- Having achieved demanded result, release the button — within several seconds of the display the modified compass reading will be displayed.

|
Arrangement near a compass of the magnetized objects, and also movement within zones of magnetic anomalies can exert considerable impact on the accuracy of compass indications! |
|
|
At the movement in a zone of magnetic anomaly correction of compass readings is made automatically — it is usually enough to make one-two turns during the movement. |
If the automatic proofreader of a compass does not cope with an objective, necessary fine tuning can be made manually.
|
|
- Bring the car to the extensive open area.
- Hold the button of management of the display pressed within about 10 seconds — the direction sign has to begin to blink.
- Slowly moving make several turns.
