freightliner Run Smart ARGOSY, Driver Manual

Page: 109 / 166

IMPORTANT: In either mode, it is possible to
shift manually by moving the lever up or down
as needed. When the engine speed is within 75
rpm of the load-based shift point for an auto-
matic shift, the TCU will advance the shift.
In either mode, the gear indicator displays the cur-
rent gear. See
Fig. 15.3 .
At the start of a shift, the current gear continues to
display until the transmission has been pulled into
neutral. As the transmission is synchronizing for the
new (target) gear, the gear indicator flashes the num-
ber of the target gear.
When the shift is complete, the gear indicator dis-
plays the new gear, without flashing.
Automatic Mode (AUTO)
In automatic drive mode (AUTO), upshifts and down-
shifts are made by the transmission without driver
intervention. Press the neutral lock button, move the
gear selector switch to drive (D), and depress the
accelerator pedal. The transmission will shift auto-
matically.
If driving conditions require, it is still possible to re-
quest a manual shift. The transmission will make the
shift if the engine speed is within 75 rpm of the load-
based shift point for that gear.
If the driver depresses the accelerator pedal after a
manual downshift in automatic mode, the transmis-
sion will upshift again if the TCU requires it.
Manual Mode (MAN)
In manual drive mode (MAN), upshifts and down-
shifts are made by the driver.
•
To upshift, pull the lever up (towards the
driver).
•
To downshift, push the lever down (away from
the driver).
The system will hold the current gear until the driver
requests a shift. In downhill situations in particular,
the driver must be alert to vehicle speed by down-
shifting and/or using the service brakes as needed.
A shift request will be refused if the selected gear
would cause engine overspeed or excessive lugging.
Start Up
1. With the parking brake set, select neutral (N) by
moving the gear selector switch to the N posi-
tion.
2.
Turn on the ignition switch. The CHECK TRANS
and TRANS TEMP lamps illuminate and go out
again (bulb check).
The gear indicator shows the dot display, ar-
ranged in a square pattern. All dots in the pattern
should illuminate, without gaps or spaces. See
Fig. 15.4 .
