2009 Acura RL Owner's Manual

If the system senses a likely collision
with a vehicle or object ahead of you,
it alerts you with an audible and a
visual alarm.The audible alarm is a constant
beeping sound; the visual alert is an
amber colored BRAKE message that
f lashes on the multi-inf ormation
display. If these alarms come on,
take the appropriate means to
prevent a collision (apply the brakes,
change lanes, etc.).To turn the CMBS off, press the
CMBS OFF switch on the dashboard
f or about 1 second. When you do this,
a beeper sounds, a CMBS indicator
on the instrument panel comes on,
and a CMBS OFF message appears
on the multi-information display. To
turn the system back on, press the
switch again for about 1 second.

The CMBS will automatically
recover when these conditions are
improved.
Any of the conditions below can
cause the CMBS to shut of f . When
the system shuts off, the CMBS
indicator in the instrument panel
comes on, and a CHECK CMBS
SYSTEM message appears on the
multi-inf ormation display f or about 5
seconds.
An abnormal tire condition is
detected (wrong tire size, f lat tire,
etc.).
Extended of f -road or mountainous
driving.
Driving your vehicle with the
parking brake applied.
Driving your vehicle in bad
weather(rain,fog,snow,etc.).
A dirty emblem on the f ront grille.
When you turn the ignition switch to
the ON (II) position, the CMBS is
turned on if it was on previously.

The CMBS indicator normally comes
on under these conditions:When you manually turn of f the
system.
When the system shuts off
automatically.
When you drive in bad weather
(rain, snow, f og, etc.). When the VSA system indicator
comes on (see page ).
When you turn the ignition switch
to the ON (II) position, the CMBS
indicator should come on f or a f ew
seconds, then go of f . If the
indicator comes on at any other
time and a CHECK CMBS
SYSTEM message appears on the
multi-inf ormation display, there is
a problem with the CMBS. You
can still drive your vehicle, but
CMBS will not be operating. Have
your vehicle checked by a dealer.
If anything covers the f ront grille
(dirt, mud, dry leaves, wet snow,
etc.).
This indicator comes on f or several
seconds when you turn the ignition
switch to the ON (II) position. It also
comesonandstaysonwhenyou
turn the CMBS off by pressing the
CMBS OFF switch.
To turn the CMBS back on, make
sure the vehicle is stopped and the
ignition switch is in the ON (II)
position, then press the CMBS OFF
switch f or about 1 second. 435

Even with little or no chance of a
collision, the CMBS may activate
under these conditions:
A vehicle suddenly crosses in f ront
of you. When you approach or pass a
vehicle ahead of you that is
turning lef t or right in an
intersection.
When you change lanes quickly,
then overtake the vehicle ahead of

When you pass a low bridge at
high speed.When you approach train tracks at
the bottom of a hill and you do not
apply the brakes.Because of the road condition
(curved, winding, etc.) or the state of
your vehicle (turning angle, lane
position, etc.), CMBS can sometimes
mistake a stationary object (light
pole, traf f ic sign, etc.) as a vehicle
ahead of you and temporarily
operate. This is normal.
When you go over a sharp-edged
speed bump at high speed.
When you go over areas of

Important Saf ety Reminder
Collision Mitigation Brake System (CMBS)

2009 RL

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. Refer to page for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to f lash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ).
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
The multi-inf ormation display also
shows a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure as indicated on the
vehicle’s tire inf ormation placard.
Driving on a signif icantly under
inf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly. For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinf lated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
youcheckandadjustyourtire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinf lated.
However, the low tire pressure/
TPMS indicator will not come on if
thetiresareoverinflated.
