Acura 2008 RL - Manual (Page 384)

Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page
).
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
This switch is at the right side of the
left vent. Press it to turn VSA on and
off.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
