1-4. SRS Air Bags
Supplemental Restraint System (SRS) Pre-
cautions
The front and side supplemental rest raint systems (SRS) include up to
6 air bags. Please verify which ki nds of air bags are equipped on your
vehicle by locating the “SRS AIRBAG” location indicators. These indi-
cators are visible in the area where the air bags are installed.
The air bags are installed in the following locations: • The steering wheel hub (driver air bag)
• The front passenger dashboard (front passenger air bag)
• The outboard sides of the front seatbacks (side air bags) (if equipped)
• The front and rear window pillars, and the roof edge along both
sides (curtain air bags) (if equipped)
The air bag supplemental restrain t systems are designed to provide
supplemental protection in certain situations so seat belts are always
important in the following ways:
Without seat belt usa ge, the air bags cannot provide adequate protec-
tion during an accident. Seat be lt usage is necessary to:
• Keep the occupant from being thrown into an inflating air bag.
• Reduce the possibility of injuries during an accident that is not designed for air bag inflation, such as rear impact.
• Reduce the possibility of injuries in frontal, near frontal or side colli-
sions or roll-over accidents that are not severe enough to activate
the air bags.
• Reduce the possibility of being thrown from your vehicle.
• Reduce the possibility of injuries to lower body and legs during an
accident because the air bags provid e no protection to these parts
of the body.
• Hold the driver in a position which allows better control of the vehi-
cle.

WARNING
■Make sure the mounting surfaces of the wheel, hub and lug nuts
are clean before changing or replacing tires
When changing or replacing a tire, not removing dirt and grime from the
mounting surfaces of the wheel, hub and hub bolts is dangerous. The
lug nuts could loosen while driving a nd cause the tire to come off, result-
ing in an accident.
■Do not apply oil or grease to lug nuts and bolts and do not tighten
the lug nuts beyond the recommended tightening torque
Applying oil or grease to lug nuts and bolts is dangerous. The lug nuts
could loosen while driving and cause the tire to come off, resulting in an
accident. In addition, lug nuts and bolts could be damaged if tightened
more than necessary.
■Always securely and correctly tighten the lug nuts
Improperly or loosely tightened lug nuts are dangerous. The wheel
could wobble or come off. This could result in loss of vehicle control and
cause a serious accident.
■Be sure to reinstall the same nuts you removed or replace them
with metric nuts of the same configuration
Because the wheel studs and lug nuts on your Toyota have metric
threads, using a non-metric nut is dan gerous. On a metric stud, it would
not secure the wheel and would damage the stud, which could cause
the wheel to slip off and cause an accident.
■Do not drive with any tires that have incorrect air pressure
Driving on tires with incorrect air pressure is dangerous. Tires with
incorrect pressure could affect handling and result in an accident. When
you check the regular tires’ air pressure, check the spare tire, too.
