6. 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]
When the speedometer reading is
40 km/h, V
1
becomes 40 km/h. Thus
the tester speed (V
2
) shall be as
follows:
30.91 km/h ≤ V
2
≤ 40 km/h
[NOTICE]
Perform the measurement with the 3rd axle, and
place the 4th axle on the free roller.
Make sure to set the inter-axle differential lock to
ON (pilot lamp lights up).
7. Emergency accelerator switch
1. While the shift lever is in the N position, turn the
emergency accelerator switch ON.
2. Slightly depress the accelerator pedal, and check
that the engine speed becomes as the value
below.
Engine speed: 2270 ± 50 min
-1
8. Emergency transmission switch
1. While in the High position and the shift lever is in
the N position, turn the emergency transmission
switch ON.
2. Set the shift lever to the D position, and check
that only the transmission state indication "D" is lit
on the combination meter.
(When the emergency transmission switch is OFF,
both "D" and "1" light up.)
3. Slightly depress the accelerator pedal, then
operate the shift lever as 1 → 2 → D, and check
that the transmission state indication of
combination meter changes as 2 → 3 → D.
[NOTICE]
Because the over-shifting prevention function does
not work while the emergency transmission switch
is ON, perform the downshifting with the vehicle
parked.
