Automatic Throttle Up (Standard)
This feature automatically increases engine speed
when the lift function or one of the tilt functions is
applied. The relationship between lever movement
and engine speed increase is defined in a graph dis-
played on the screen. Maximum engine speed in-
crease is 80% for lift and tilt functions. The Auto-
matic Throttle Up feature is only active when the
transmission is NOT in gear or when it is in in-
ching mode.
HiP/ECO eLo Operating Mode (Standard)
The ECO elo feature allows the operator to choose
between high performance (HiP) or fuel efficiency
(ECO elo) modes. Selection between the HiP and
ECO modes is made by means of a key switch loca-
ted on the side console.
The High Performance mode (HiP) provides the
normal engine settings and performance behavior.
The ECO eLo mode smoothens throttle reaction
time, therefore increasing fuel efficiency. Engine
speed is only reduced when the transmission is en-
gaged or when a hydraulic function is applied. Max-
imum engine speed is reduced to 2000 rpm.
Drive Over Lift (Standard)
The Drive Over Lift feature prioritizes driving per-
formance over lift performance when driving and
lifting occur at the same time.
The amount of lifting performance is reduced by
disabling the second lift section. The second lift sec-
tion is disabled under the following circumstances:
• The transmission is engaged (Driving/Not In-
ching)
• Engine speed is less than 1350 rpm
FAN Drive System (Standard)
The FAN drive system is a standard feature that
proportionally controls the cooling performance of
the cooling fan. Depending on four temperature in-
puts, the hydraulic controller determines the out-
put for the FAN drive system. See Table 3.
The Minimum and Maximum input temperatures
determine the normal operating range, with the
Minimum input corresponding to 10% cooling per-
formance and the Maximum input corresponding to
90% cooling performance.
When one of the temperature inputs exceed the
Limit temperature input, the output for the fan
drive is set to 100% cooling performance.
Hibernate Idle (Standard Tier 4 Only)
The Hibernate Idle feature ramps down engine
speed if the truck has been left to idle without oper-
ator interaction for 30 seconds (no hydraulic opera-
tions or accelerator pedal have been applied), to im-
prove fuel economy during extended idle periods.
Engine speed is ramped up when one of the hy-
draulic functions is applied or when the accelerator
pedal is applied. When the calibration switch is ac-
tivated the hibernate idle function is disabled, al-
lowing the truck to be calibrated.
