matic transmissions, are also available.
Active Brake Assist 5 provides full
braking when approaching stopped or
moving vehicles and pedestrians. On
the ACM test track, a ride-along demo
illustrated the effectiveness of the
ABA5 system, bringing the M2 Plus
truck traveling at 35 mph (56 km/h) to
a complete stop just inches shy of a
static obstacle in the road.
" In the vocational market, safety is
not just becoming cost of entry; for
many customers it's required to do
business, " Scates said. Other safety features
include Lane Departure Warning
and optional Side Guard Assist, which
informs the driver when a pedestrian,
object or vehicle is on the passenger
side of the vehicle. An amber light on
the A-pillar warns the driver when an
object is there; the light turns red and
an audible alert sounds if the driver attempts
to change lanes or make a turn.
There is no active steering assistance on
M2 and SD Plus models.
Adaptive Cruise Control works down
to 10 mph (16 km/h), and Intelligent High
Beam Assist automatically turns high
beam off when encountering oncoming
vehicles. Outfitted with the Detroit
Connect suite of connectivity systems,
Plus series fleets will receive key information
about vehicle performance. The
Virtual Technician remote diagnostic
service informs fleets within minutes of a
fault event of its severity, and when,
where and how to best fix the issue.
Remote Updates uses over-the-air programming
capabilities to make engine
parameter and other updates.
Detroit Connect Analytics provide users
with on-demand, automated analysis,
identifying behaviors and trends, and
providing actionable insights on fuel
consumption and safety performance
data. Safety Event Viewer enables visibility
into driver safety performance, notifying
fleets of collision mitigation events.
Upfit efficiency
A major focus for engineers was TEM
(truck equipment manufacturers) integration
and upfit efficiency. Again, the
new electrical architecture enables
Freightliner to offer the QuickFit

System and programmable modules
together with the CHEC Tool. The CHEC
Tool provides a user-friendly interface
to view and modify electrical configurations
and change parameters in minutes,
according to DTNA.
" That allows TEMs to integrate their
software body controls, configure
switches, create interlocks, all located
on our architecture, " Scates said. " The
advantage for a TEM who works with
DTNA on multiple product lines is really
the upfit methodology. The way
that they connect to the vehicle both
in terms of software and also their

Better fit and finish to reduce squeaks and rattles, and more insulation in the roof and backwall help
to reduce cab noise by 1 dB.
