1. Air pressure is 540 kPa (5.5 kgf/cm
2
) (78.3 psi) or less,
when the main switch is turned ON and the parking
brake is not applied.
2. Shift lever is out of N position when the parking brake is
applied.

(10.2 kgf/cm
2
) (145 psi) or less while the parking brake is
not applied.
2WD/4WD select
• 620 Hz
• Continuous beep
(high tone)
Buzzer sounds if the vehicle speed exceeds 1.0 km/h
when the 2/4-wheel switch condition disagrees with the

oil temperature
• 620 Hz
• Continuous beep
(high tone)
It is not necessary to check because the buzzer
structurally sounds when oil temperature exceeds 110°C
(230°F) if vehicle speed exceeds 0.6MPH.

7. Speedometer
(1 km/h = 0.6214 MPH)
When the actual traveling speed of the vehicle is V
2
,
the reading of the speedometer (V
1
) shall meet the
following formula:
0 V
1
- V
2
V
2
/ 10 + 6
Ex. Case of a vehicle of [45 km/h
<
Vmax
55 km/h]
V
1
= 40 km/h
When the speedometer reading is 40 km/h, the
tester speed V
2
shall be as follows:
30.91 km/h V
2
40 km/h
