tion, and goes off when the engine is
started.

running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact your Toyota

ately.
Loose fuel tank cap

after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...

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.
If engine speed does not increase when
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.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.

cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.

and down between fourth gear and
overdrive when climbing a gentle slope,
shift the selector lever to the “4” posi-

the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
