Acura 2012 RL - Manual (Page 336)

This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. If it comes on at any other
time, there is a problem in the ACC
system. If this happens, take the
vehicle to your dealer to have it
checked.
The vehicle speed decreases
below 22 mph (35 km/h).
Driving on a mountainous road, or
driving off road for extended
periods.
When the ABS or VSA is activated.
Abrupt steering wheel movement.
Poor weather (rain, fog, snow, etc.)
When the radar sensor in the front
grille gets dirty.
The vehicle ahead of you cannot
be detected.
An abnormal tire condition is
detected, or the tires are skidding.
When ACC is automatically canceled,
the beeper sounds about 1 second,
and an ACC OFF message appears
on the multi-information display for 3
seconds.
Any of these conditions may cause
ACC to cancel:
The ACC system cannot be used
while this indicator (amber) is on.
When the VSA system indicator
comes on.
If you turn the ignition switch to the
ACCESSORY (I) or LOCK (0)
position after ACC was automatically
canceled, the set speed is erased,
and you must enter it again (see
page
).
If ACC is canceled by any these
conditions, wait until the condition
improves, then press the RES/
ACCEL button to restore ACC.
When you do this, the vehicle will
resume its set cruising speed.
