1-7. Safety information

Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment po wer for the driver and front pas-
senger. The driver airbag system consists of the driver seat’s position
sensor etc. The front passenger’s airbag system consists of the front
passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants.

Front passenger occupant cl assification system precautions
l If an adult sits in the front passenger seat, the AIR BAG ON indicator light
is illuminated. If the AIR BAG OFF indicator is illuminated, ask the passen-
ger to sit up straight, well back in the seat, feet on the floor, and with the

nated, either ask the passenger to move to the rear seat, or if that is not
possible, move the front passenger seat fully rearward.

on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( →

If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light
not come on when you start the engine, this could mean that these systems
are not available to help protect you in an accident, which could result in
death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.

the lights do not turn off. Have the vehicle inspected by your Toyota
dealer.

When driving
CAUTION
nStopping distance when the ABS is ope rating on the wet or slick roads
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
l When driving on dirt, gravel or snow-covered roads
l When driving with tire chains
l When driving over bumps in the road
l When driving over roads with potholes or uneven roads
n When VSC is activated
The slip indicator flashes and a warning buzzer sounds. Always drive care-
fully. Reckless driving may cause an accident. Exercise particular care when
the indicator flashes and a buzzer sounds.
n TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
n Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC will not function correctly if different tires are fitted on the
vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
n Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.
