Vehicle Stability Assist (VSA
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 Activation Indicator
When VSA activates, you will see the
VSA activation indicator blink (see
page 69).
Vehicle Stability Assist
(VSA) System Indicator
If this indicator comes on while
driving, 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 or comes
back on while driving, have the VSA
system inspected by your dealer.
NOTE: The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function.
2011 RDX
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.
You will also see a ''CHECK VSA
SYSTEM'' message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on (see page 390),
or the multi-information display
shows a ''CHECK TPMS SYSTEM''
message with the indicator flashing
(see page 393), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
