(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
switch is set at ON and goes off after
the engine starts. This means that the
warning light system is operating prop-
erly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
D
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
D
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
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...
D
There is a problem somewhere in the
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 engine off.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.

Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle's
emission control system and
(On- Board Diagnostics) system before
taking your vehicle for the inspection.
For details, see "Emissions Inspection and
Maintenance (I/M) programs" on page 340

(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
