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.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.

(g) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the
distance driven exceeds 8000 km (5000
miles), the light will come on after the
ignition key is turned to “ON” position.
The light will remain on thereafter. If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the
engine oil replacement. Reset the system
by the following procedure:
1. Turn the ignition key to the “OFF” posi- tion with the odometer reading shown.
(For details, see “Odometer and two
trip meters” on page 154 in this Sec-
tion.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset knob.
Hold down the knob for at least 5
seconds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing.
(h) 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. (i) “ABS” Warning Light
Without the vehicle stability control
system—
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
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist system still operates.
In this case, 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 the light remains on.

sure of one or more of your tires (includ-
ing the spare tire) is low. The light comes
on when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the light comes on, stop your vehicle in
a safe place as soon as possible and
check that the tire inflation pressure of all
tires (including the spare tire) is as
specified on the tire and loading
information label. (See “Checking tire
inflation pressure” on page 373 in Section

If the “4LO” (low speed four−wheel drive)
indicator light continues to blink when you
operate the front drive control switch knob
to the “H4” or “L4” position, drive forward
or backward in a short distance, then stop
the vehicle completely, shift the automatic
transmission selector lever securely into
“N” and operate the switch knob again.
If the indicator continues to blink even if
doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the four −wheel drive system.
CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
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 to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
