sensor ACURA ZDX 2010 Owners Manual

Your vehicle is equipped with many
features that work together to protect
you and your passengers during a
crash.
Some features do not require any
action on your part. These include a
strong steel framework that forms a
safety cage around the passenger
compartment, front and rear crush
zones, a collapsible steering column,
and tensioners that tighten the front
seat belts in a crash.
However, you and your passengers
can't take full advantage of these
features unless you remain sitting in
the correct position and
always wear
your seat belts.
In fact, some safety
features can contribute to injuries if
they are not used properly.
The following pages explain how you
can take an active role in protecting
yourself and your passengers.

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 498) and the
brake pedal assist function (see page
495). 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 Belts2409/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

Your Airbag System (SRS) includes:●Two SRS (Supplemental Restraint
System) front airbags. The driver's
airbag is stored in the center of the
steering wheel; the front passenger's
airbag is stored in the dashboard.
Both are marked‘‘SRS AIRBAG ’’
(see page 28).●Two side airbags, one for the driver
and one for a front passenger. The
airbags are stored in the outer edges
of the seat-backs. Both are marked
‘‘ SIDE AIRBAG ’’(see page 32).●Two side curtain airbags, one for
each side of the vehicle. The airbags
are stored in the roof above the side
windows. The front and rear pillars
are marked ‘‘SIDE CURTAIN
AIRBAG ’’(see page 33).
●On models with CMBS, front seat
belt e-pretensioners (see page 24).●Automatic front seat belt tensioners
(see page 23).●Sensors that can detect a moderate
to severe front impact, side impact,
or if your vehicle is about to rollover.●Sensors that can detect whether a
child is in the passenger's side
airbag path and signal the control
unit to turn the airbag off (see page
33).●Sensors that can detect whether the
driver's seat belt and the front
passenger's seat belt are latched or
unlatched (see page 21).●A driver's seat position sensor that
monitors the distance of the seat
from the front airbag. If the seat is
too far forward, the airbag will inflate
with less force (see page 31).
●Weight sensors that monitor the
weight on the front passenger's seat.
If the weight is about 65 lbs (29 kg)
or less (the weight of an infant or
small child), the passenger's front
airbag will be turned off (see page
31).●A rollover sensor that can detect if
your vehicle is about to roll over and
signal the control unit to deploy both
side curtain airbags (see page 34).

●A sophisticated electronic system
that continually monitors and
records information about the
sensors, the control unit, the airbag
activators, the seat belt tensioners,
and driver and front passenger seat
belt use when the ignition switch is
in the ON (II) position.
Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON mode is the equivalent of
ON (II). For more information, see
pages 194 and 196.●An indicator on the instrument panel
that alerts you to a possible problem
with your airbag system components
(see page 34).●An indicator on the instrument panel
that alerts you that the passenger's
side airbag has been turned off (see
page 35).
●An indicator on the dashboard that
alerts you that the passenger's front
airbag has been turned off (see page
36).●Emergency backup power in case
your vehicle's electrical system is
disconnected in a crash.
How Your Front Airbags WorkIf you ever have a moderate to severe
frontal collision, sensors will detect
the vehicle's rapid deceleration.
If the rate of deceleration is high
enough, the control unit will inflate
the driver's and front passenger's
airbags, at the time and with the
force needed.

Dual-Stage AirbagsYour front airbags are dual-stage
airbags. This means they have two
inflation stages that can be ignited
sequentially or simultaneously,
depending on crash severity.
In a
more severe
crash, both stages
will ignite simultaneously to provide
the quickest and greatest protection.
In a
less severe
crash, one stage will
ignite first, then the second stage will
ignite a split second later. This
provides longer airbag inflation time
with a little less force.
Dual-Threshold AirbagsYour front airbags are also dual-
threshold airbags. Airbags with this
feature have two deployment
thresholds that depend on whether
sensors detect the occupant is
wearing a seat belt or not.
If the occupant's belt is
not latched,
the airbag will deploy at a slightly
lower threshold, because the
occupant would need extra
protection.
If the occupant's belt is
latched,
the
airbag will inflate at a slightly higher
threshold, when the airbag would be
needed to supplement the protection
provided by the seat belt.
Advanced AirbagsYour front airbags are also advanced
airbags. The main purpose of this
feature is to help prevent airbag-
caused injuries to short drivers and
children or small statured adults who
ride in front.
For both advanced airbags to work
properly:●Occupants must sit upright and
wear their seat belts properly.●Do not spill any liquids on or
under the seats, cover the sensors,
or put any objects or metal items
under the front seats.
Failure to follow these instructions
could damage the sensors or prevent
them from working properly.

The driver's advanced front airbag
system includes a seat position
sensor under the seat. If the seat is
too far forward, the airbag will inflate
with less force, regardless of the
severity of the impact.
If there is a problem with the sensor,
the SRS indicator will come on, and
the airbag will inflate in the normal
manner regardless of the driver's
seating position.
The passenger's advanced front
airbag system has weight sensors
under the seat. Although Acura does
not encourage carrying an infant or
small child in front, if the sensors
detect the weight of an infant or
small child (up to about 65 lbs or 29
kg), the system will automatically
turn the passenger's front airbag off.Be aware that objects placed on the
passenger's seat can also cause the
airbag to be turned off.
When the passenger airbag gets
turned off by the weight sensors, a
‘‘
passenger airbag off ’’indicator in
the center of the dashboard comes
on (see page 36).
If the weight sensors detect there is
no passenger in the front seat, the
airbag is automatically turned off.
However, the passenger airbag off
indicator in this situation will not
come on.
To ensure that the passenger's
advanced front airbag system will
work properly,
do not do anything
that would increase or decrease the weight on the front passenger's seat.
This includes:●A rear passenger pushing or
pulling on the back of the front
passenger's seat.

●Moving the front seat forcibly back
against cargo on the seat or floor
behind it.●Hanging heavy items on the front
passenger seat, or placing heavy
items in the seat-back pocket.●Moving the front passenger's seat
or seat-back forcibly back against
the folded rear seat.●Back seat passengers should not
wedge objects or intentionally
force their feet under the front
passenger seat.
Also, make sure the floor mat behind
the front passenger's seat is hooked
to the floor mat anchor (see page
563). If it is not, the mat may
interfere with the proper operation of
the sensors and operation of the seat. How Your Side Airbags Work
If you ever have a moderate to severe
side impact, sensors will detect rapid
acceleration and signal the control
unit to instantly inflate either the
driver's or the passenger's side
airbag.
Only one airbag will deploy during a
side impact. If the impact is on the
passenger's side, the passenger's
side airbag will deploy even if there
is no passenger.
To get the best protection from the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.

Side Airbag Cutoff SystemYour vehicle has a side airbag cutoff
system designed primarily to protect
a child riding in the front passenger's
seat.
Although Acura does not encourage
children to ride in front, if the
position sensors detect a child has
leaned into the side airbag's
deployment path, the airbag will shut
off.
The side airbag may also shut off if a
short adult leans sideways, or a
larger adult slouches and leans
sideways into the airbag's
deployment path.
Objects placed on the front
passenger seat can also cause the
side airbag to be shut off.If the side airbag off indicator comes
on (see page 35), have the passenger
sit upright. Once the passenger is
out of the airbag's deployment path,
the system will turn the airbag back
on, and the indicator will go out.
There will be some delay between
the moment the passenger moves
into or out of the airbag deployment
path and when the indicator comes
on or goes off.
A front seat passenger should not
use a cushion or another object as a
backrest. It may prevent the cutoff
system from working properly.
How Your Side Curtain Airbags
Work
In a Side ImpactIn a moderate to severe side impact,
sensors will detect rapid acceleration
and signal the control unit to
instantly inflate the side curtain
airbag.
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.

How the Passenger Airbag Off
Indicator WorksThis indicator alerts you that the
passenger's front airbag has been
shut off because weight sensors
detect about 65 lbs (29 kg) or less
(the weight of an infant or small
child) on the front passenger's seat.
It does
not mean
there is a problem
with the airbag. Be aware that objects placed on the
front seat can cause the indicator to
come on.
If no weight is detected on the front
seat, the airbag will be automatically
shut off. However, the indicator will
not come on.
The passenger airbag off indicator
may come on and off repeatedly if the
total weight on the seat is near the
airbag cutoff threshold.
If an adult or teenage passenger is
riding in front, move the seat as far to
the rear as possible, and have the
passenger sit upright and wear the
seat belt properly.
If the indicator comes on with no
front seat passenger and no objects
on the seat, or with an adult riding
there, something may be interfering
with the weight sensors. Look for
and remove:
●Any items under the front
passenger's seat.●Any object(s) hanging on the seat
or in the seat-back pocket.●Any object(s) touching the rear of
the seat-back.
If no obstructions are found, have
your vehicle checked by a dealer as
soon as possible.
