uuSeat Belts uAbout Your Seat Belts
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 reduc e 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 belt s. Devices intended to improve comfort 
or reposition the shoulder part of a seat  belt 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
1About Your Seat Belts
If a rear seat passenger moves around and extends 
the seat belt, the lockable retractor may activate. If 
this happens, release the  retractor by unfastening the 
seat belt and allow the belt to retract completely. 
Then refasten the belt.
1 Seat Belt Reminder
The indicator will also co me on if a front passenger 
does not fasten their seat be lt within 6 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 not come on and the 
beeper may not sound when the occupant is not 
heavy enough to trigger th e 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. 2 Protecting Child Passengers  P. 62

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s and passenger’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 ro llover. 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.
bTwo front knee airbags. The driver’s knee 
airbag is stored under the steering 
column. The front passenger’s knee 
airbag is stored under the glove box. 
Both are 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 they 
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.

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  towards 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 towards 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

Make sure the floor mat  behind the front passenger’s 
seat is hooked to the floor  mat anchor. An improperly 
placed mat can interfere with the advanced airbag

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 systems se nses 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 to not 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 
about 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. 62
If the front passenger’s seat is empty, the in dicator will come on and, in the event of 
a crash, the front passenger’s airbag wi ll not deploy. The front passenger’s knee 
airbag will not deploy either.
■Passenger Front Airbag Off Indicator1 Passenger Front Airbag Off Indicator
To ensure the passenger is  detected properly, confirm 
that:
•There is no child seat or  other object pressing 
against the rear of the seat-back.
•There is no rear passenger pushing or pulling on 
the back of the front passenger’s seat.
•The front seat or seat-b ack is not forced back 
against an object on the s eat or floor behind it.
•There is no object placed under or beside the front 
passenger’s seat.
•The occupant is sitting in  an upright position and 
the seat back is not  excessively reclined.
•The occupant is not leaning against the door or 
center console.
•The occupant’s feet are plac ed on the floor in front 
of them.
•There are no objects ha nging from the front 
passenger’s seat.
•Only small, lightweight objects are in the seat-back 
pocket.
The passenger front airbag  off indicator may come 
on and go off periodically if  the total weight on the 
seat is near the airbag cutoff threshold.
Have your vehicle checked  by a dealer as soon as 
possible if:
•All of the above conditions are met, and the 
indicator comes on with an adult seated in the 
front passenger seat.
•The seat is empty and the indicator is off.
Do not allow an adult passe nger to ride in the front 
seat when the indicator is on.
