VSA® (Vehicle Stability Assist), aka ESC (Electronic 
Stability Control), System
VSA® helps to stabilize the vehicle during cornering 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 engine output and selectively applying the brakes.
When VSA® activates, you may notice that the 
engine does not respond to the accelerator. 
You may also notice some noise from the 
hydraulic system. You will also see the 
indicator blink.

VSA® Operation
1
VSA® (Vehicle Stability Assist), aka ESC (Electronic Stability 
Control), System
The VSA® may not function properly 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® indicator comes on and stays on 
while driving, there may be a problem with the 
system. While this may not interfere with normal 
driving, have your vehicle checked by a 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 always 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.
