Toyota Highlander Owners Manual: SRS airbags
The srs airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury to the
occupants. They work together with the seat belts to help reduce
the risk of death or serious injury.
Srs front airbags
- Srs driver airbag/front passenger airbag
can help protect the head and chest of the driver and front passenger
from impact with interior components
- srs driver’s knee airbag
can help provide driver protection
- srs seat cushion airbag
can help restrain the front passenger
Srs side and curtain shield airbags
- Srs side airbags
can help protect the torso of the front seat occupants
- srs curtain shield airbags
- Can help protect primarily the head of occupants in the outer
seats
- Can prevent the occupants from being thrown from the vehicle
in the event of vehicle rollover
Srs airbag system components
- Front passenger airbag
- curtain shield airbags
- side impact sensors (front
doors)
- “air bag on” and “air bag
off” indicator lights
- seat belt pretensioners and
force limiters
- side airbags
- seat cushion airbag
- srs warning light
- driver airbag
- side impact sensors (rear)
- front passenger’s seat belt
buckle switch
- driver’s seat position sensor
- driver’s seat belt buckle
switch
- driver’s knee airbag
- front passenger occupant
classification system (ecu
and sensors)
- front impact sensors
- airbag sensor assembly
Your vehicle is equipped with advanced airbags designed based
on the us motor vehicle safety standards (fmvss208). The airbag
sensor assembly (ecu) controls airbag deployment based on information
obtained from the sensors etc. Shown in the system components
diagram above. This information includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants.
Warning
Srs airbag precautions
observe the following precautions regarding the srs airbags.
Failure to do so may cause death or serious injury.
Since the risk zone for the driver's airbag is the first 2 - 3 in.
(50 - 75 Mm)
of inflation, placing yourself 10 in. (250 Mm) from your driver airbag
provides
you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less
than 10
in. (250 Mm) away now, you can change your driving position in several
ways:
- Move your seat to the rear as far as you can while still
reaching the pedals
comfortably.
- Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in.
(250
Mm) distance, even with the driver seat all the way forward, simply
by
reclining the back of the seat somewhat. If reclining the back of
your
seat makes it hard to see the road, raise yourself by using a firm,
nonslippery
cushion, or raise the seat if your vehicle has that feature.
- If your steering wheel is adjustable, tilt it downward.
This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by nhtsa above, while
still maintaining control of the foot pedals, steering wheel, and your
view
of the instrument panel controls. |
Warning
srs airbag precautions
- If the seat belt extender has been connected
to the front seat belt buckles but
the seat belt extender has not also been
fastened to the latch plate of the seat
belt, the srs front airbags will judge
that the driver and front passenger are
wearing the seat belt even though the
seat belt has not been connected. In
this case, the srs front airbags may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.
|
Warning
Srs airbag precautions
- do not allow a child to stand in front of
the srs front passenger airbag unit or
sit on the knees of a front passenger.
- Do not allow the front seat occupants to
hold items on their knees.
- Do not lean against the door, the roof
side rail or the front, side and rear pillars.
- Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
|
Warning
srs airbag precautions
- Do not attach anything to areas such as
a door, windshield, side window, front or
rear pillar, roof side rail and assist grip.
- Vehicles without a smart key system:
do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
srs driver’s knee airbag inflation or be
thrust into the driver’s seat area by the
force of the deploying airbag, thus causing
a danger.
- Do not hang coat hangers or other hard objects on the coat
hooks. All of
these items could become projectiles and may cause death or serious
injury, should the srs curtain shield airbags deploy.
?œIf a vinyl cover is put on the area where the srs driver's knee
airbag will
deploy, be sure to remove it.
- Do not use seat accessories which cover the parts where the srs
side
airbags and srs seat cushion airbag inflate as they may interfere
with
inflation of the airbags. Such accessories may prevent the side
airbags
and seat cushion airbag from activating correctly, disable the
system or
cause the side airbags and seat cushion airbag to inflate
accidentally,
resulting in death or serious injury.
- Do not strike or apply significant levels of force to the area
of the srs airbag
components.
Doing so can cause the srs airbags to malfunction.
- Do not touch any of the component parts immediately after the
srs airbags
have deployed (inflated) as they may be hot.
- If breathing becomes difficult after the srs airbags have
deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is
safe to do
so. Wash off any residue as soon as possible to prevent skin
irritation.
Srs airbag precautions
- If the areas where the srs airbags are stored, such as the
steering wheel
pad and front and rear pillar garnishes, are damaged or cracked,
have
them replaced by your toyota dealer.
- Do not place anything, such as a cushion, on the front
passenger's seat.
Doing so will disperse the passenger's weight, which prevents the
sensor
from detecting the passenger's weight properly. As a result, the srs
front
airbags for the front passenger may not deploy in the event of a
collision.
Modification and disposal of srs airbag system components
Do not dispose of your vehicle or perform any of the following
modifications
without consulting your toyota dealer. The srs airbags may malfunction
or
deploy (inflate) accidentally, causing death or serious injury.
- Installation, removal, disassembly and repair of the srs airbags
- repairs, modifications, removal or replacement of the steering
wheel,
instrument panel, dashboard, seats or seat upholstery, front, side
and rear
pillars or roof side rails
- repairs or modifications of the front fender, front bumper or
side of the
occupant compartment
- installation of a grille guard (bull bars, kangaroo bar, etc.),
Snow plows,
winches or roof luggage carrier
- modifications to the vehicle's suspension system
- installation of electronic devices such as mobile two-way radios
and cd
players
- modifications to your vehicle for a person with a physical
disability
|
If the srs airbags deploy (inflate)
- Bruising and slight abrasions may result from contact with a deploying
(inflating) srs airbag.
- A loud noise and white powder will be emitted.
- Parts of the airbag module (steering wheel hub, airbag cover and
inflator) as
well as the front seats, parts of the front and rear pillars, and roof side
rails
may be hot for several minutes. The airbag itself may also be hot.
- The windshield may crack.
- For u.S.A.: For safety connect subscribers, if the srs airbags deploy or
in
the event of a severe rear-end collision, the system is designed to send an
emergency call to the response center, notifying them of the vehicle's
location
(without needing to push the "sos"¸ button) and an agent will attempt to
speak with the occupants to ascertain the level of emergency and assistance
required. If the occupants are unable to communicate, the agent
automatically
treats the call as an emergency and helps to dispatch the
necessary emergency services.
Srs airbag deployment conditions (srs front airbags)
- if the vehicle strikes an object, such as a parked vehicle or sign
pole,
which can move or deform on impact
- if the vehicle is involved in an underride collision, such as a
collision in
which the front of the vehicle "underrides"¸, or goes under, the bed of a
truck
- depending on the type of collision, it is possible that only the seat
belt pretensioners
will activate.
- The srs front airbags for the front passenger will not activate if there
is no
passenger sitting in the front passenger seat. However, the srs front
airbags
for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
- The srs seat cushion airbag on the front passenger"¦s seat will not
operate
if the occupant is not wearing a seat belt.
Srs airbag deployment conditions (srs side and curtain shield airbags)
- the srs side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force
corresponding
to the impact force produced by an approximately 3300 lb. [1500 Kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the
vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
- The srs curtain shield airbags will deploy in the event of vehicle
rollover.
- The srs side and curtain shield airbags may also deploy in the event of
a
severe frontal collision.
Conditions under which the srs airbags may deploy (inflate), other than a
collision
The srs front airbags and srs side and curtain shield airbags may also
deploy if a serious impact occurs to the underside of your vehicle. Some
examples are shown in the illustration.
- Hitting a curb, edge of pavement or hard
surface
- falling into or jumping over a deep hole
- landing hard or falling
The srs curtain shield airbags may also deploy under the situations shown
in the illustration.
- The angle of vehicle tip-up is marginal
- The vehicle skids and hits a curb stone
Types of collisions that may not deploy the srs airbags (srs front
airbags)
The srs front airbags do not generally inflate if the vehicle is involved in
a
side or rear collision, if it rolls over, or if it is involved in a low-speed
frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the srs front airbags may occur.
- Collision from the side
- Collision from the rear
- Vehicle rollover
Types of collisions that may not deploy the srs airbags (srs side and
curtain shield airbags)
The srs side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
- ?Collision from the side to the vehicle
body other than the passenger compartment
- Collision from the side at an angle
The srs side airbags do not generally inflate if the vehicle is involved in a
rear collision, if it rolls over, or if it is involved in a low-speed side or
lowspeed
frontal collision
- Collision from the rear
- Vehicle rollover
The srs curtain shield airbags do not generally inflate if the vehicle is
involved in a rear collision, if it pitches end over end, or if it is involved
in a
low-speed side or low-speed frontal collision.
- Collision from the rear
- Pitching end over end
When to contact your toyota dealer
In the following cases, the vehicle will require inspection and/or repair.
Contact
your toyota dealer as soon as possible.
