ACC does not work below 25 mph
(40 km/h). It cannot bring your
vehicle to a complete stop.
ACC will not sound a beeper or
display a message on the multi-
inf ormation display to warn you of
vehicles going slower than 13 mph
(20 km/h) or vehicles that are
parked. In these cases, it is up to
you to maintain a safe distance by
using the brake pedal.
ACC may not recognize
motorcycles or other small
vehicles ahead of your vehicle.ACC may react to vehicles beside
you or even a building beside you
by momentarily applying the
brakes or sounding a beeper under
conditions such as a sudden curve
or narrowing of the road, an
abrupt movement of the steering
wheel, or if you are in an unusual
position within your lane.

Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
saf ety systems could make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer.
Raising your vehicle with a non-
Acura suspension kit can af f ect
the handling and stability. Lowering the vehicle with a non-
Acura suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Removing parts f rom your vehicle,
or replacing components with non-
Acura components could seriously
af f ect your vehicle’s handling,
stability, and reliability.
Herearesomeexamples:
Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
