Passmart; Electronic Stability Control (Esc) - freightliner M2 Plus 2023 Manual

•
IPM may automatically engage the engine
brake at a higher speed than the cruise set
speed.
•
If IPM becomes unavailable, conventional
cruise control can still function.
WARNING
Apply the brakes and downshift as necessary
when driving on downhill grades. IPM does not
adequately control vehicle speed on steep
downhill grades. Failure to use normal braking
techniques when IPM is active could result in
personal injury and vehicle damage.
IMPORTANT: IPM adjusts the vehicle set speed
to achieve maximum fuel economy, but it does
not account for traffic flows or surrounding
vehicles.
For best fuel-savings, use cruise control whenever
possible. Driver interaction with IPM is the same as
standard adaptive cruise control. In the event of a
problem with IPM, or when driving on a road with no
profile information available, the system reverts to
standard adaptive cruise control.
Using the accelerator pedal cancels the current IPM
session. Disengaging the cruise control also
deactivates IPM.

PasSmart

A standard feature on fleet vehicles, PasSmart
enables a vehicle to exceed a set speed limit by a
limited amount to allow for passing vehicles on the
highway. For example, a PasSmart vehicle may be
programmed to enable the vehicle to travel 5mph
over a set speed limit for 30 minutes every 24 hours.
This speed limiting increases overall fuel economy.
If equipped, the PasSmart function is initiated by
double-pumping the accelerator pedal within a two
second period. When initiated, the PasSmart window
as shown in Fig. 7.11 appears. The PasSmart timer
shown in this window starts when the road speed
limit is exceeded by 1.89 mph (3 km/h).
PasSmart does not disengage cruise control. After
engagement, PasSmart deactivates when the speed
limit of the vehicle drops below the cruise control
standard set speed limit at which point cruise control
resumes.

Thirty seconds before a daily PasSmart limit is
reached, the PasSmart active window, if closed,
opens to notify the driver of the time remaining.
Electronic Stability Control
(ESC)
WARNING
ESC is intended only as an aid for a
conscientious and alert driver. Carefully read the
information in this manual to understand this
system and its limitations. ESC is not a
substitute for safe driving procedures. Failure to
drive safely, and use the system properly, could
result in personal injury and/or death and
property damage.
CAUTION
Changing or modifying the location of the ESC
sensor or reconfiguring the vehicle, such as by
changing the wheelbase or adding axles, can
change the performance of the enhanced stability
control system and may result in product or
property damage and personal injury.
Electronic stability control (ESC) works by constantly
comparing the driver's intention with the vehicle's
actual behavior. The system does this by monitoring
wheel speed, steering angle, yaw rate, lateral
acceleration, throttle position, and brake application.
