lane assist Acura MDX 2013 Owner's Manual

The tensioners can be activated
during a collision in which the front
airbags
do not deploy.
In this case, the
airbags would not be needed, but the
extra tension in the seat belt could be
helpful.
If the tensioner is activated, the SRS
indicator comes on and the tensioner
must be replaced.Seat Belt e-pretensioners
On models with Collision Mitigation
Braking 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 463) and the
brake pedal assist function (see page
460).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).

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 473).
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 88).
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 473.
This indicator may also come on if
there is a problem with the trailer
stability assist function (see page
498).
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 473.
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 529). 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.

If equippedThe 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.
