If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “− SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction. On vehicles with automatic transmission,
even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. To decrease the
vehicle speed, reset to a slower speed
with the cruise control lever or depress
the brake pedal. If you use the brake
pedal, cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the “+ RES” direction will re-
store the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “ON
−OFF” button
to turn the system off and then press it
again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.
