2011 ACURA RL sensor

Adaptive cruise control (ACC) allows
you to maintain a set speed and keep
the vehicle ahead of you and your
vehicle at a saf e distance without
having to use the accelerator pedal
or the brake pedal.If the vehicle ahead of you slows
down suddenly or another vehicle
cuts in f ront of your vehicle, ACC
alerts you by sounding a beeper and
displaying a message on the multi-
inf ormation display.
TheACCradarsensorinthefront
grille can detect and monitor the
distance of a vehicle up to 328 f eet
(100 meters) ahead of your vehicle.
For more inf ormation on the radar
sensor, see page .Do not use ACC under these
conditions:
In poor visibility.
In heavy traffic.
When you must slow down and
speed up repeatedly.
On winding roads.
When you enter a toll gate,
interchange, service area, parking
area, etc. In these areas, there is
no vehicle ahead of you, and ACC
would still try to accelerate to your
set speed.
In bad weather (rain, f og, snow,
etc.)
On a slippery road (f or example a
road covered with ice or snow).
As with any system, there are limits
to ACC. Inappropriate use of ACC
can result in a serious accident. Use
the brake pedal whenever necessary,
and always keep a safe distance
between your vehicle and other
vehicles.
When the vehicle ahead of you slows
down or speeds up, ACC senses the
change in distance and compensates
by accelerating or braking your
vehicle to reach the cruising speed
you previously set. The distance
between vehicles is based on your
speed: the f aster you go, the longer
the distance will be; the slower you
go, the shorter it will be.

This indicator normally comes on f or
a f ew 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
below22mph(35km/h). Driving on a mountainous road, or
driving of f road f or extended
periods.
When the ABS or VSA is activated. Abrupt steering wheel movement.
Poor weather (rain, f og, 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-inf ormation display f or 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 af ter 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. 324

If equipped
Your vehicle has a backup sensor
system. This system lets you know
theapproximatedistancebetween
your vehicle and most obstacles with
an audible signal while you are
parking.
Thesensorsareinstalledintherear
bumper. There are two corner
sensors, one on each side, and two
center sensors in the middle of the
rear bumper.The system is activated and a beeper
sounds once when you put the
transmission into reverse. As your
vehicle is nearing an obstacle, the
system makes the audible signal to
let you know the approximate
distance between your vehicle and
the obstacle. If there are more than
two obstacles around the rear
bumper, the system inf orms you of
the nearest obstacle’s distance f rom
the rear bumper.
All obstacles may not always be
sensed. Even with this system, you
should look f or obstacles near your
vehicletomakesureitissafetopark.The beeping changes according to
the distance between the rear
bumper and an obstacle:

The range of the corner sensors and
the rear center sensors are limited.
Each corner sensor is capable of
sensing an obstacle within about 24
in (60 cm).The rear center sensors sense an
obstacle within about 59 in (150 cm).
Do not put any accessories on or
around the sensors.The system may not f unction
properly under these conditions:
The sensors are covered with
snow,ice,mud,etc.
When the vehicle is on a rough
road, on grass, or on a hill.
After the vehicle has been sitting
out in hot or cold weather.
When the system is af f ected by
some electrical equipment or
devices generating an ultrasonic
wave.
When operating the vehicle in bad
weather.

The system may not sense thin or
low objects, or sonic-absorptive
materials such as snow, cotton, or
sponge.
The system cannot sense objects
directly under the bumper.
If a beeper sounds several times or
does not sound when you put the
transmission into reverse, there is a
problem with the backup sensor
system. You should have the system
checked by your dealer.Canadian Owners:This device complies with IndustryCanada Standard RSS-210. Operation issubject to the f ollowing two conditions:(1) this device may not causeinterf erence, and (2) this device mustaccept any interf erence that may causeundesired operation of the device.
