vehicle.
Warnings and Cautions
for Engine Exhaust
(Carbon monoxide)
WARNING
Do not drive your vehicle if you smell
exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This
gas contains carbon monoxide (CO),
which is colorless, odorless, and
poisonous. When inhaled, it can cause
loss of consciousness and death. If you

Secondary CollisionReduction
*
The Secondary Collision Reduction
reduces secondary damage by
decelerating the vehicle when it is
damaged in a collision to the extent
that the airbags are deployed while
driving.
If a collision occurs to the extent that
the airbags are deployed while driving,
the hazard warning lights flash to alert
surrounding vehicles and the brakes
are controlled to reduce damage in the
event of a collision with an obstruction
or other object.
Warnings and Cautions
for Using the Secondary Collision Reduction
WARNING
Do not rely completely on the
Secondary Collision Reduction.
The Secondary Collision Reduction
may not operate normally depending
on various conditions such as the
accident condition, component part
damage condition, target object
condition, weather conditions, or
