Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System
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 surfaces. It does this
by regulating the engine's output,
and by selectively applying the
brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
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.

VSA Off Indicator
When VSA is off, the VSA off
indicator comes on as a reminder.
Vehicle Stability Assist
(VSA) System Indicator
When VSA activates, you will see the
VSA system indicator blink.
If this indicator comes on while
driving, you will also see a ''CHECK
VSA SYSTEM'' and/or ''CHECK
HILL START ASSIST SYSTEM''
message on the multi-information
display. Drive cautiously as the VSA
may not be functioning. Without
VSA, your vehicle will have normal
braking and cornering ability, but it
will not have VSA traction and
stability enhancement. Also, the VSA
OFF switch will not operate. Pull to
the side of the road when it is safe,
and turn off the engine. Reset the
system by restarting the engine. If
the VSA system indicator stays on,
2010 TL
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.
: Models equipped with the
keyless access system have an
engine start/stop button instead
of an ignition switch. ON Mode
is the equivalent of ON (II). For
more information, see pages
178 and 181 .
NOTE: The main function of the
VSA system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function.
