Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating motor out put and selectively applying the brakes.
When VSA ® activates, you may notice that the
motor does not respond to the accelerator.
You may also notice some noise from the
hydraulic brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Fuel Ce ll dealer immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and alwa ys leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not

You may hear a sound coming from the motor
