EXTERIOR SOUND
Unlike a traditional vehicle powered by an
internal combustion engine, electric
vehicles are inherently quiet at low speeds.
Although this potentially provides a large
benefit by reducing the levels of traffic
noise from passing vehicles, sound also
acts as a warning to other road users. It
signifies the presence of a vehicle, its
speed, direction and acceleration.
To help reduce this safety risk, your Revero
has been equipped with an exterior sound
system to alert pedestrians and other road
users to your presence.
Two speakers are located on the exterior of
your Revero, one under the front of the
vehicle and another under the rear.
USING THE SYSTEM
Note: The exterior sound system is
controlled automatically by the vehicle.
There is no need for driver intervention.
When the vehicle is put into Drive mode, the
exterior sound system is switched on. A
pulsing sound will be heard from the
exterior speakers.
As the vehicle’s speed increases, the pitch
of the sound increases until the vehicle’s
speed reaches approximately 30 mph
(50 km/h). At this speed the volume of the
sound will fade out and the exterior sound
is turned off.
The exterior sound will remain off until the
vehicle’s speed is reduced to
approximately 28 mph (45 km/h). At this
speed, the exterior sound is switched on
and the sound will fade in. As the vehicle
slows, the pitch of the sound will decrease.
Note: The exterior sound system remains
active even when the vehicle is in [P] Park.
