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.

■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 scrape s, 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 airb ags have been specifically designed to help reduce the 
severity of injuries that can occur during 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 he lp 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.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver's seat position 
sensor or the passenger's s eat weight sensors, the 
SRS indicator will come on, and in the event of a 
crash, the airbag will deploy (regardless of the driver's 
seating position or  passenger's occupant 
classification) with a fo rce corresponding to the 
severity of the impact. 2 Supplemental Restraint System (SRS) 
Indicator  P. 56
For the advanced front airbags to work properly, 
confirm that:
•The occupant is sitting  in an upright position, 
wearing the seat belt prope rly 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 objec ts are in the seat back 
pocket.
•The steering wheel and passenger's side dashboard 
are not obstructed by any object.
•No liquid has been spille d on or under the seat.•There is no child seat or other object pressing 
against the rear of the seat or seat back.
•There is no rear passenger pushing or pulling on 
the back of the front passenger's seat.

The front passenger's ad vanced airbag system 
has weight sensors. The sensors are used for 
occupant classification to activate or 
deactivate the front  passenger's airbag.
For adult size occupants, the system will 
automatically activate the front passenger's 
airbag. If a small adult sits in the front 
passenger seat and the system does not 
recognize him/her as an adult, see
2 Passenger Front Airbag Off Indicator  P. 57
We advise against allowing a child age 12 or 
under to ride in the front passenger's seat. 
However, if you do allow a small child or 
infant to ride in the front passenger's seat, the 
system is designed to automatically deactivate 
the front passenger's airbag. Do not let a 
small child or infant ride in the front 
passenger’s seat if the airbag does not 
automatically deactivate.

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 replacing or 
covering front seat-back cove rs can prevent your side 
airbags from properl y deploying during a side impact.

■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
Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and passengers in the 
outer seating positions during a moderate-to -severe side impact. The side curtain 
airbags equipped in this vehicle are also  designed to help reduce the likelihood of 
partial and complete ejection of vehicle occupants through side windows in crashes, 
particularly rollover crashes.
The side curtain airbags are located in the 
ceiling above the side windows on both sides 
of the vehicle.
The side curtain airbag is designed to deploy 
in a rollover or a moderate-to-severe side 
impact.
■Housing Locations
1 Side Curtain Airbags
To get the best protecti on from the side curtain 
airbags, occupants should wear their seat belts 
properly and sit upr ight and well back in their seats.
Do not attach any objects to the side windows or roof 
pillars as they can interfere with the proper operation 
of the side curtain airbags.
If the SRS control unit sens es that your vehicle is 
about to rollover, it imme diately deploys both side 
curtain airbags and activates both front seat belt 
tensioners.
If the impact is on the passenger's side, the 
passenger's side curtain airbag deploys even if there 
are no occupants on that side of the vehicle.

If a problem occurs in the airbag syst em, the SRS indicator will come on and a 
message appears on the driver information interface.
■When the power mo de is set to ON
The indicator comes on  for a few seconds, 
then goes off. This tells you the system is 
working properly.
If the indicator comes on at any other time, or 
does not come on at all, have the system 
checked by a dealer as s oon as possible. If you 
don’t, your airbags and seat belt tensioners 
may not work properly  when they are needed.

Safe Driving■When the passenger front airbag off 
indicator comes on
The indicator comes on to alert you that the 
front passenger's airbag  has been turned off. 
This occurs when the weight sensors 
determine that a small child or infant is on the 
passenger seat.
Children age 12 or under should always ride 
properly restrained in a back seat.
2 Child Safety P. 60
Objects placed on the seat can also cause the 
indicator to come on. If the indicator is on in 
the event of a crash, the front passenger's 
airbag will not deploy.
If the front passenger's seat is empty, the 
front passenger's airbag will not deploy and 
the indicator will not come on.

1Passenger Front Airbag Off Indicator
The passenger airbag off  indicator may come on and 
go off periodically if the tota l weight on the seat is 
near the airbag cutoff threshold. For a small adult, 
depending on physique and posture, the system may 
not recognize him/her as an adult and thus deactivate 
the front passenger's airbag.
If this occurs, please confirm that the conditions set 
forth in the above bullet  points on the previous page 
are met.
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 on.
Do not allow an adult passe nger to ride in the front 
seat when the indicator is on.
