speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the front passen-

engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself. Contact your Toyota dealer as soon as
possible to service the vehicle.

the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.

throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition switch is turned to the “ACC”
or “LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state

Brake assist system
Traction control system
“AUTO LSD” system
Vehicle stability control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition switch is turned to the “ON”
position, or remains on.

ing light, immediately stop your ve-
hicle at a safe place and contact your
