Toyota 2003 Tundra Owner's Manual page 50

The SRS airbags are designed to deploy
in severe (usually frontal) collisions
where the magnitude and duration of
the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when the
vehicle has the impact straight into a fixed
barrier that does not move or deform.
However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if the vehicle is involved in an
underride collision (e.g. a collision
which the front of the vehicle "underrides",
or goes under, the bed of a truck, etc.).
It is possible that in some collisions
where the forward deceleration of the ve-
hicle is very close to the designed thresh-
old level, the SRS airbags and front seat
belt pretensioners may not activate togeth-
er.
Always wear your seat belts properly.

Collision from the rear
Collision from the side
Vehicle rollover
The SRS airbags are generally not de-
signed to inflate if the vehicle is in-
volved in a side or rear collision, if it
in
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, de-
ployment of the SRS airbags may oc-
cur.
Hitting a curb,
edge of pavement
or hard material
Landing hard or vehicle falling
The SRS airbags may also deploy if a
serious impact occurs to the underside
of your vehicle. Some examples are
shown in the illustration.
