3. Connect the three dry cell batteries (1.5 V) in a series.

4. Connect auto leveling sensor terminal A to the battery’s minus terminal, and terminal C to the battery’s plus terminal, and apply 4.5 V of voltage between terminals A and C.
5. Connect the tester as shown in the figure.
6. When slowly moving the link up and down, verify that the shift is linear while the voltage is 0.5 to 4.5 V.

If the voltage cannot be verified as indicated in the graph, replace the auto leveling sensor.

Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help ...
