When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.When VSA activates, you will see the
VSA activation indicator blink (see
page ).
The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output and
by selectively applying the brakes. If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible (see page ).
Without VSA, your vehicle still has
normal braking and cornering ability,
but it does not have VSA traction and
stability enhancement.
The VSA system indicator may come
on along with the ABS indicator if
there is a problem with the anti-lock
brake system.
The main f unction of the
VSA system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control f unction. 50
