2011 Acura MDX turn signal

The BSI alert indicator starts to blink
as a reminder if you move the turn
signal lever in the direction of the
detected vehicle.
Radar sensors, located underneath
each corner of the rear bumper,
detect objects. Do not cover this area
with labels or stickers of any kind.
Always keep this area is free of any
kind of dirt every time you get in the
vehicle.
Impacts to the radar sensors or the
area around them can affect system
performance. If an impact occurs,
have the system checked by your
dealer.

Trailer LightsTrailer lights and equipment must
comply with federal, state, province,
and local regulations. Check trailer
light requirements for the areas
where you plan to tow, and use only
equipment designed for your vehicle.
Your vehicle is equipped with a
connector to install an optional trailer
lighting connector that mates with
your vehicle. You can get this
optional connector from your dealer.Refer to the above illustration for
wiring information.
We recommend that you have your
dealer install an Acura wiring
harness and converter. This harness
has been designed for your vehicle.If you use a non-Acura trailer lighting
harness and converter, you can get
the mating connector and pins that
mate with the connector in your
vehicle from your dealer.
Since lighting and wiring vary with
trailer type and brand, you should
also have a qualified mechanic install
a suitable connector between the
vehicle and the trailer.

Under these conditions, trailer
stability assist begins to stabilize the
vehicle/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressure on the brake pedal.
When the brakes are applied, the
trailer's brake lights come on along
with the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
system indicator blink. There may
also be some noise from the VSA
hydraulic system.Trailer stability assist cannot prevent
a loss of control. Always reduce the
vehicle speed and steer firmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailer to jackknife or turn over and
the system becomes ineffective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicle/trailer
combination in these conditions,
after the oscillation becomes severe.
Trailer stability assist will also be
ineffective while driving at high
speed or towing a trailer with a high
center of gravity.
Always obey the recommended
speed limits for towing a trailer, see
page 491.Trailer Stability Assist Failure
The control unit monitors the VSA
circuitry and the braking system. If
there is a problem with the brake
lighting system, the trailer stability
assist function shuts down and the
‘‘
CHECK TRAILER STABILITY
ASSIST ’’message appears on the
multi-information display.
If you see this message, have your
vehicle checked at your dealer as
soon as possible.
