Toyota 4Runner 2003 Operating Manual page 127

When you drive for about 8000 km (5000
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 "ON" posi-
tion. If you continue driving without the
engine oil replacement, and if the driving
range exceeds 12000 km (7500 miles), the
light will come on after the ignition key is
turned to "ON" position. The light will re-
main 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 condition. If the light comes on, re-
place it as soon as possible.
You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:
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 114 in this sec-
tion.)
2. Turn the ignition key to the "ON" posi-
tion while holding down the trip meter
reset button.

Hold down the button until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will
remain flashing.
(i) "ABS" Warning Light
The light comes on when the ignition key
is turned to the "ON" position. If the anti–
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the "ABS" warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
D
Anti–lock brake system
D
Brake assist system
D
Traction control system
(two–wheel drive models)
D
Active traction control system
(four–wheel drive models)
D
Vehicle skid control system
D
Downhill assist control system
(four–wheel drive models)
D
Hill–start assist 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
occurs, this indicates
somewhere in the parts monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
D
The light does not come on when the
ignition key is turned to the "ON" posi-
tion, or remains on.
D
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
