display Acura MDX 2012 Owner's Manual

Radar SensorThe radar sensor is located under the
Acura emblem in the front grille. If
the radar sensor cover is covered
with mud, dirt, dead leaves, wet
snow, etc., or if you put a sticker on
it, the CMBS will automatically shut
off, and the CMBS indicator on the
instrument panel will come on. You
will also see a‘‘CHECK CMBS
RADAR SENSOR’’message on the
multi-information display for about 5
seconds.
Always keep the radar sensor cover
clean. If it gets dirty, clean it with
water or a mild detergent. Never use
chemical solvents or polishing
powder.
There are three bolts on the sides of
the radar sensor. Do not tamper with
these bolts, or you may cause the
system to malfunction.Do not allow anything to impact the
radar sensor or the radar sensor
cover. If either of these parts receives
a strong impact, switch the system
off by pressing the CMBS off button,
and have your vehicle checked by a
dealer. If the front grille ever needs
to be repaired, consult a dealer first.
If the radar sensor cover or the radar
sensor ever needs to be removed,
take your vehicle to a dealer.
When the CMBS is on, the radar sensor
constantly scans for vehicles directly
ahead of you. This means that driving
on a road with a few or no vehicles
could cause a CHECK CMBS RADAR
SENSOR message to appear on the
multi-information display. This is
normal and not a cause for concern.

Collision Mitigation Braking System™(CMBS™)464

Certain conditions may cause the
radar aim to be temporarily out of
proper range, such as the following
two examples:●
Your vehicle is tilted because of a
heavy load in the rear or from
modifications to the suspension.
Do not overload your vehicle (see
Carrying Cargo on page 433), and
do not make any modifications to
the suspension (see Accessories
and Modifications on page 431).
●
The tires are not correctly
maintained. Always make sure the
tire pressures are correct (see
page 540), and that the tires are
the correct size and in good
condition (see Tires on page 540).Collision Alert
If the system senses a likely collision
with a vehicle or object ahead of you,
it alerts you with a visual alert or a
combination of a visual alert and an
audible alert.
The visual alert is an amber colored
BRAKE message that flashes on the
multi-information display, the audible
alert is a constant beeping sound. If
one or more of the alerts come on,
take the appropriate means to
prevent a collision (apply the brakes,
change lanes, etc.).

●
When the VSA system indicator
comes on (see page 473).
●
When you turn the ignition switch
to the ON (II) position, the CMBS
indicator should come on for a few
seconds, then go off. If the
indicator comes on at any other
time and a CHECK CMBS
SYSTEM message appears on the
multi-information 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.Limitations
The CMBS may not activate under
some conditions. Here are a few
examples:
●
The distance between your vehicle
and the vehicle ahead of you is too
short.
●
A vehicle cuts in front of you at a
slow speed, or it brakes suddenly.
●
When you accelerate rapidly and
approach the vehicle ahead of you
at high speed.
●
Immediately after you begin
driving.

You will also see a‘‘CHECK VSA
SYSTEM’’message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM’’message with the
indicator flashing (see page 458), the
VSA system automatically turns on
even if the VSA system is turned off
by pressing the VSA OFF button. If
this case, you cannot turn the VSA
system off by pressing the VSA OFF
button again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.VSA Off Button
This switch is under the driver's side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA off
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on. With the
VSA off, the trailer stability assist
function is also turned off (see page
498).VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.

Driving

The system provides two selectable
modes.
Sport mode: The system prioritizes
handling response, vehicle body
control and tire-to-road adhesion to
allow for higher performance
handling.
Comfort mode: The system
prioritizes road isolation to allow for a
more comfortable ride.
Either mode can be used in any type
of operating conditions, but the mode
may change temporarily to suit a
change in road surface.
To switch between comfort and sport
mode, press and release the active
damper system button located on the
center console to choose the desired
mode.
When comfort mode is selected, the
green indicator in the button comes
on, and the message‘‘COMFORT’’
will appear on the multi-information
display for five seconds.
