er, if a front passenger uses an additional

when the seat belt is not buckled up.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, builtin
sensors in the seat cushion may detect
the pressure, causing the reminder light to
come on. (d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.

after taking several driving trips.
If the lamp will not go off even after the

tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.

tor pedal more firmly and slowly, you can
drive your vehicle at low speeds. Have
your vehicle checked by your Toyota deal-
er as soon as possible.

Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for a state emission
inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 276
in Section 6.(f) 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.
(g) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system, the traction con-
trol system (twowheel drive vehicles), the
active traction control system (fourwheel
drive vehicles) and the vehicle skid con-
trol system do not operate, but the brake
system still operates conventi
onally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces. If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts 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 key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the traction
control system is in the selfcheck mode,

come on when the ignition is turned on,
contact your Toyota dealer.

4 wheels (4WD mode) or rear wheels
(2WD mode) when the vehicle is started
or accelerated on slippery road sur-
faces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels (4WD mode)
or rear wheels (2WD mode) cannot be
maintained, even though the active
traction control system is in opera-
tion. Do not drive the vehicle under
any speed or maneuvering conditions
which may cause the vehicle to lose
traction control. In situations where
the road surface is covered with ice
or snow, your vehicle should be fitted
with snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

brakes and engine to help prevent the
vehicle from skidding when cornering
on a slippery road surface or operating
steering wheel abruptly.
The vehicle skid control activates when
the vehicle speed is more than the follow-
ing speed.

You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the system is
in the selfcheck mode but does not indi-
cate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, you must always drive
carefully and attentively to avoid
serious injury. Reckless driving will
result in an unexpected accident. If
the slip indicator light flashes,
sounding an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacture, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 289 in Section 72.)
