Noise Emissions
Every eCascadia is equipped with an acoustic
vehicle alerting system (AVAS). The AVAS makes the
minimum noise possible to alert pedestrians,
bicyclists, and other non-motorized road users of the
presence and approach of the vehicle.
Each vehicle is equipped with two AVAS speakers.
One is located at the front of the vehicle as shown in
Fig. 20.1 and the other is attached on the inside rear
of the right-hand frame rail. Fig. 20.2 shows the
location on a 6x4 vehicle with a fifth wheel.
Each vehicle has a defined AVAS sound, built upon
the vehicle noise profile, which cannot be adapted to
personal preferences.
The AVAS generates noise when the key is in the
ON position and the park brake is released. While
driving or when the vehicle is in neutral, sound is
broadcast through the front speaker. When the
vehicle is in reverse, sound is broadcast through the
rear speaker.
When speeding up, the volume of the AVAS sound
increases until maximum volume is reached at about
19 mph (30 km/h). This volume is maintained until
approximately 60 mph (97 km/h) at which point it
turns off. It turns on again when the vehicle slows
down to around 20 mph (32 km/h).
The rear speaker will broadcast a beeping sound
when the vehicle is in reverse. If the vehicle has
been ordered with a backup alarm, this beep will
sound
like an electric alarm clock. If the vehicle is
ordered with no backup alarm, the reverse beep alert
will sound
like someone regularly striking a high-
pitched key on a piano. The back-up volume is set
by the factory and cannot be changed; vehicle speed
does not affect the back-up sound volume.
Any deactivation of AVAS imperils the safety of other
road users and is strongly discouraged.
Greenhouse Gas Emissions
Model year 2013 and later vehicles must meet
requirements as specified by EPA10, GHG14,
GHG17 and GHG21 regulations. See Table 1.1 and
Table 1.2 in
Chapter 1 for additional information on
what EPA and GHG regulations apply to different
eCascadia model years.
Model year 2013 and later vehicles are equipped
with components that increase energy efficiency such
as low-rolling resistance tires, vehicle speed limiters,
and aerodynamic devices such as the hood, cab side
extenders, and chassis side fairings.
It is a violation of U.S. federal law to alter
components that would bring the vehicle out of
compliance with certification requirements [Ref: 42
U.S.C. S7522(a) (3)]. It is the owner’s responsibility
to maintain the vehicle so that it conforms to all EPA
regulations.
