lane assist Acura MDX 2011 Owner's Manual

Seat Belt e-pretensionersOn models with Collision MitigationBraking System ™(CMBS ™)For added safety, the front seat belts
are equipped with e-pretensioners
that work in combination with the
collision mitigation braking system ™
(CMBS ™) (see page 457) and the
brake pedal assist function (see page
454). 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 front of
you is likely, the e-pretensioners on
both front seats retract the seat belts
with enough force to properly
restrain you and your front
passenger. After they activate, the e-
pretensioners release the retracted
seat belts.
To get the full benefit of the e-
pretensioners, you and your front
passenger must sit normally in your
seats and wear your seat belts
properly (see page 16).
The e-pretensioners do not activate
when the vehicle stability assist
(VSA) off indicator on the instrument
panel is on.If the automatic seat belt tensioners
are activated by a collision, both front
seat belts and all related components
must be replaced (see page 25). If
only the e-pretensioners were
activated, no components need to be
replaced.
In addition, the front 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
front passenger's seat.Additional Information About Your Seat Belts2410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

Vehicle Stability Assist
(VSA) System Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. It flashes when VSA is
active (see page 467).
If it comes on and stays on at any
other time, there is a problem with
the VSA or Hill Start Assist system.
You will also see a ‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display (see page 87).
Take your vehicle to a dealer to have
it checked. Without VSA, your
vehicle still has normal driving
ability, but will not have VSA traction
and stability enhancement. For more
information, see page 467.
This indicator may also come on if
there is a problem with the trailer
stability assist function (see page
492).
VSA Off Indicator
It comes on as a reminder that you
have turned off the vehicle stability
assist (VSA) system.
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. For more information, see
page 467.
Turn Signal and
Hazard Warning
Indicators
The left or right turn signal indicator
blinks when you signal a lane change
or turn. If an indicator does not blink
or blinks rapidly, it usually means
one of the turn signal bulbs is burned
out (see page 523). Replace the bulb
as soon as possible, since other
drivers cannot see that you are
signaling.
When you press the hazard warning
button, both turn signal indicators
and all turn signals on the outside of
the vehicle flash.

U.S. Advance Package, AdvancePackage with Entertainment, andCanadian Elite Package modelsThe blind spot information system
(BSI) is designed to assist you when
you are changing lanes. If the system detects vehicles in
adjacent lanes, it automatically
illuminates the appropriate indicator
to provide assistance when you
change lanes. It is not a substitute for
visual confirmation that it is safe to
change lanes.
Failure to visually confirm that it
is safe to change lanes before
doing so may result in a crash
and serious injury or death.
Do not rely only on the blind
spot information system when
changing lanes.
Always look in your mirrors, to
either side of your vehicle, and
behind you for other vehicles
before changing lanes.

Important Precautions
Like all assistance systems, BSI has
limitations. Over-reliance on BSI may
result in a collision. Always look in
your mirrors, to either side of your
vehicle, and behind you for other
vehicles before changing lanes.The system should be turned off
when towing a trailer. Due to the
added mass and resulting changes in
radar coverage, the system cannot
operate as intended, and detection of
the trailer itself by the radar sensors
may cause the BSI alert indicators to
illuminate.Limitations
The BSI alert indicators may not
illuminate under the following
circumstances:
●
The speed difference between
your vehicle and a vehicle
approaching from behind is
greater than 31 mph (50 km/h).
●
A vehicle is parked in a side lane.
●
The speed difference between
your vehicle and the vehicle you
are passing is greater than 6 mph
(10 km/h).
●
An object not detected by the
radar sensors approaches or
passes your vehicle.
