deploy at the same time as the driver’s and

Even if the collision is not severe enough to
deploy the front airbags, the knee airbags may
inflate alone.

■When knee 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 knee 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.

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.

■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 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 the SRS control unit sens es that your vehicle is
about to rollover, it imme diately deploys both side
curtain airbags and activates the seat belt tensioners
for the front seats a nd outer rear seats.

Airbag System Indicators
If a problem occurs in the airbag system , the SRS indicator will come on and a
message appears on the multi-information display.
■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 soon as po ssible. If you don’t, your airbags and seat
belt tensioners may not work properly when they are needed.

Ignoring the SRS indicator can result in
serious injury or death if the airbag systems
or tensioners do not work properly.
Have your vehicle checked by a dealer as
soon as possible if th e SRS indicator alerts
you to a possible problem.

indicator comes on
The indicator comes on to alert you that the
passenger’s airbag has been turned off.
This occurs if the seat is empty or when the
weight sensors determine that a small child or
infant is on the passenger seat.
Children age 12 or under shou ld always ride properly restrained in a back seat.
2Child Safety P. 64
If the indicator is on, in the event of a cr ash the passenger’s airbag will not deploy.
The passenger’s knee airbag will not deploy, either.
■Passenger Airbag Off Indicator1 Passenger Airbag Off Indicator
To ensure the passenger is detected 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 objects are in the seat-back
pocket.
•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.
•There are no objects placed under or beside the
front passenger’s seat . Improperly positioned
objects can interfere with the advanced airbag
sensors.
•The floor mat behind the front passenger’s seat is
set in the correct position evenly on the floor. An
improperly placed mat can interfere with the
advanced airbag sensors.
•The head restraint is not contacting the roof.

1Passenger 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 passenger’s airbag.
If this occurs, please confirm that the conditions set
forth in the above bullet points on the previous page
are met.
If the above conditions are met and the indicator is
still on, then with the transmission in park, turn the
ignition off and back on.
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.
