AcuraWatchTM
AcuraWatchTM is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located behind the emblem and a front
sensor camera mounted to the interior side
of the windshield, behind the rearview
mirror.
The camera is located
behind the rearview
mirror.
The radar sensor is
behind the emblem.

Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching and leaning reduce the effectiveness of the
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat be lts. Devices intended to improve comfort
or reposition the shoulder part of a seat be lt can reduce the protective capability
and increase the chance of serious injury in a crash.
The seat belt system includes an indicator on
the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts.
If you set the power mode to ON and a seat
belt is not fastened, a beeper will sound and
the indicator will blink. After a few seconds,
the beeper will stop and the indicator will
come on and remain illuminated until the seat
belt is fastened.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.
■Seat Belt Reminder
1 About Your Seat Belts
If a front passenger and rear seat passenger moves
around and extends the seat belt, the lockable
retractor may activate. If this happens, release the
retractor by unfastening th e seat belt and allow the
belt to retract completely. Then refasten the belt.
1 Seat Belt Reminder
The indicator will also come on if a front passenger
does not fasten their seat belt within six seconds after
the power mode is set to ON.
When no one is sitting in th e front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may no t come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them.

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, front side, and side
curtain airbags are deployed according to
the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:
aTwo 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.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo 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 .
dTwo side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
eAn electronic control unit that, when the
vehicle is on, continually monitors
information about the various impact
sensors, seat and buckle sensors, rollover
sensor, airbag activators, seat belt
tensioners, and other vehicle
information. During a crash event the
unit can record such information.
fAutomatic front seat belt tensioners. In
addition, the driver’s and front
passenger’s seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
gA driver’s seat position sensor. This
sensor determines the optimal force at
which the airbag will deploy in a crash.
hWeight sensors in the front passenger’s
seat. The front passenger’s airbag will be
turned off if the weight on the seat is
approximately 65 lbs (29 kg) or less (the
weight of an infant or small child).
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
kAn indicator on the instrument panel that
alerts you to a possible problem with your
airbag system or seat belt tensioners.
lSafing Sensor
mA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver’s and fr ont passenger’s airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.

uuAirbags uFront Airbags (SRS)
Safe Driving
■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrapes, or even broken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move toward the front of the vehicle. Side
airbags and side curtain airbag s have been specifically designed to help reduce the
severity of injuries that can occur durin g a moderate-to-severe side impact which
can cause the driver or passenger to move toward the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any si gnificant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy in a rollover as they would provide
little if any protection.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy, even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to help reduce the likelihood of airbag related
injuries to smaller occupants. The driver’s advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger’s ad vanced airbag system
has weight sensors.
We advise against allowi ng a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a child age 12 or
under to ride in the front passenger’s
seat , note that the system will automatically
turn off the front passenger’s airbag if the
sensors detect that the child is approximately
65 lbs (29 kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on, and in the
event of a crash, the airbag will deploy (regardless of
the driver’s seating position) with a force
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•All occupants should sit upri ght and wear their seat
belts properly.
•Do not cover the passenger ’s side dashboard with
a cloth, towel, cover, etc. 2Passenger Front Airbag Off Indicator

uuAirbags uSide Airbags
Safe Driving
Side Airbags
The side airbags help protect the torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver’s and passenger’s seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Make sure you and your front seat passenger always
sit upright. Leaning into the path of a side airbag can
prevent the airbag from deploying properly and
increases your risk of serious injury.
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replac ing or covering front seat-back
covers can prevent your si de airbags from properly
deploying during a side impact.

uuAirbags uSide Airbags
Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag not to deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.

Safe Driving■When the passenger front airbag off
indicator comes on
The indicator comes on to alert you that the
passenger’s front airbag has been turned off.
This occurs when the weight sensors detect
65 lbs (29 kg) or less, the weight of an infant
or small child, on the seat.
Children age 12 or under should always ri de properly restrained in a back seat.
2Child Safety P. 56
Objects placed on the seat can also cause the indicator to come on.
If the front passenger’s seat is empty, the passenger’s front airbag will not deploy
and the indicator will not come on.
■Passenger Front Airbag Off Indicator1Passenger Front Airbag Off Indicator
If the indicator comes on with no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors, such as:
•An object hanging on the seat or in the seat-back
pocket.
•A child seat or other obj ect pressing against the
rear of the seat-back.
•A rear passenger pushing or pulling on the back of
the front passe nger’s seat.
•The front seat or seat-back is forced back against
an object on the seat or floor behind it.
•An object placed under th e front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger front airbag off indicator may come
on and go off repeat edly if the total weight on the
seat is near the airbag cutoff threshold.
