2009 Acura TSX sensor

In a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag and activate the seat belt
tensioner on the driver’s or the
passenger’s side of the vehicle.If the impact is on the passenger’s
side, the passenger’s side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle.
One or both side curtain airbags may
inflate in a moderate to severe
f rontal collision which causes the
f ront airbags to deploy.
To get the best protection f rom the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
When you turn the ignition switch to
the ON (II) position, this indicator
comes on brief ly then goes of f . This
tells you the system is working
properly.
The SRS indicator alerts you to a
potential problem with your airbags
or seat belt tensioners.

Take your vehicle to an
authorized dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.
Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. Any
seat belt tensioner that activates
must also be replaced.
Do not try to remove or replace
anyairbagbyyourself.Thismust
be done by an authorized dealer or
a knowledgeable body shop.
Your airbag systems are virtually
maintenance f ree, and there are no
parts you can saf ely service.
However, you must have your
vehicle serviced if:
Even if your
airbags do not inflate, your dealer
should inspect the driver’s seat
position sensor, the f ront
passenger’s weight sensors, the
f ront seat belt tensioners, and all
seat belts and their anchors worn
during a crash to make sure they
are operating properly. Together, airbags and
seat belts provide the best
protection.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
If water or
another liquid soaks into a seat-
back, it can prevent the side airbag
cutoff system from working
properly.

This shows the outside Fahrenheit
temperature in U.S. models, and
Centigrade temperature in Canadian
models.In certain weather conditions,
temperature readings near f reezing
(32°F, 0°C) could mean that ice is
f orming on the road surf ace.
You can adjust the outside
temperature display (see page ).
The temperature sensor is in the
