’03 4Runner_U (L/O 0208)
143
2003 4RUNNER from Aug. ’02 Prod. (OM35795U)
The slip indicator light and downhill assist
control system indicator light come on for
a few seconds when the ignition key is
turned to “ON”. If any of the indicator
lights does not come on when the ignition
is turned on, contact your Toyota dealer.
If the system is used frequently, the
brake actuator temperature may become
too high and a buzzer will sound inter-
mittently.
If this happens, the downhill assist control
system indicator light will flash and a
buzzer will sound intermittently. When the
temperature of the brake actuator goes
down, the system will begin to operate
again. Until it restarts, the active traction
control system and hill–start assist control
system will not operate; however, the con-
ventional brake can be operated.
If there is any abnormality in the sys-
tem, the “VSC TRAC” warning light will
come on. When the “DAC” switch is
pushed, the downhill assist control sys-
tem indicator light also flash.
If the “VSC TRAC” warning light comes
on, there may be an abnormality in any
of the following systems in addition to the
downhill assist control system.
D Hill–start assist control system
D Active traction control system
D Vehicle skid control system
“VSC TRAC” warning light
When the system is normal and the igni-
tion key is turned to “ON”, the warning
light will come on and will go off after a
few seconds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to the “ON” position.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned system on such as slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
downhill assist control system can no lon-
ger operate. In this case, stop your ve-
hicle immediately at a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
