2011 ACURA RL brake sensor

For added saf ety, the f ront seat belts
are equipped with e-pretensioners
that work in combination with the
collision mitigation braking system
(CMBS ) (see page ) and the
brake pedal assist f unction (see page). If your vehicle gets too close to the
vehicle ahead of it in your lane, the
driver’s e-pretensioner slightly
retracts the seat belt to alert the
driver of the approaching vehicle. If
a collision with the vehicle in f ront of
you is likely, the e-pretensioners on
both front seats retract the seat belts
with enough f orce to properly
restrain you and your f ront
passenger. After they activate, the
e-pretensioners release the retracted
seat belts.
To get the f ull benef it of the
e-pretensioners, you and your f ront
passenger must sit normally in your
seats and wear your seat belts
properly (see page ).
The e-pretensioners do not activate
when the vehicle stability assist
(VSA) of f indicator on the
instrument panel is on.
If the automatic seat belt tensioners
are activated by a collision, both
f ront seat belts and all related
components must be replaced (see
page ). If only the
e-pretensioners were activated, no
components need to be replaced.
In addition, the f ront passenger’s
e-pretensioner does not activate
when the passenger’s airbag is
automatically turned off because the
weight sensor detects a child in the
f ront passenger’s seat.

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.

If equipped
The collision mitigation braking
system (CMBS ) can assist the
driver when there is a possibility of
colliding with the vehicle in f ront of
yours. It is designed to reduce the
speed of your vehicle bef ore an
unavoidable collision occurs and, if
possible, to alert you to a potential
collision while there is time f or the
driver to prevent it. Here is a brief
description of what the CMBS can
do:When your speed is above 10 mph
(15 km/h), the CMBS is monitoring
the vehicle ahead of you with radar.
When your vehicle is approaching
the vehicle ahead of yours too
quickly, the system may activate one
or more of the f ollowing: a visual
alert, an audible alert, apply the
brakes and e-pretensioners to
tighten the front seat belts first as
a warning, then to prepare for an
impending crash (see page ).
The CMBS consists of a radar
sensor in the f ront grille, a brake
actuator in the engine compartment,
an indicator on the instrument panel,
seat belt e-pretensioners on the f ront
seats,andanon/off buttononthe
dashboard.
