TURNING THE SYSTEM ON
To operate the cruise control, press the
ON- OFFº switch. This turns the system
on. The indicator light in the instrument
panel shows that you can now set the
vehicle at a desired cruising speed. Anoth-
er press will turn the system completely
off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the ON- OFFº switch
off when not using the cruise control.
SETTING AT A DESIRED SPEED
The transmission must be in Dº before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the - SETº direc-
tion and release it. This sets the vehicle
at that speed. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal.If you need accelerationÐfor example,
when passingÐdepress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the CANCELº
direction and releasing it.
b. Depressing the brake pedal.
c. Pushing the ON- OFFº switch.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
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 + RESº 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 - SETº direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the - SETº 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 - SETº direction.
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, pushing the lever up in the
+ RESº direction will restore 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 CRUISEº indicator light in the
instrument cluster flashes when using the
cruise control, press the ON- OFFº switch
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.

Cruise Control for 3MZ-FE
The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes
it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
1. Set Operation
When the ON-OFF SW is turned on, the system starts preparations necessary for the cruise control and turns on the
indicator light in the combination meter.
2. Set Speed Control
When the - SET SW is operated with the ON-OFF SW turned on during travelling, the constant vehicle speed is controlled.
3. Coast Control
When the - SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to
decelerate the vehicle. Every time the - SET SW is turned on instantaneously, the vehicle speed is decelerated
approximately 1.5 km/h.
4. Accel Control
When the + RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to
accelerate the vehicle. Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated
approximately 1.5 km/h.
5. Resume Control
When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use
of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control.
6. Manual Cancel Mechanism
If any of the following signals is input during cruise control travelling, the cruise control is cancelled.
*The stop light SW is turned on.
*The CANCEL SW is turned on.
*The ON-OFF SW is turned off.
*Gear is shifted from D position to other positions than D.
7. Auto Cancel Function
If any of the following conditions is encountered, the cruise control is automatically cancelled.
*The stop light SW wiring is faulty or short-circuited.
*The vehicle speed signal is faulty.
*The electronically controlled throttle malfunctions.
8. Overdrive Control Function
The overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrive
control has been cancelled, when climbing hill is judged to finish from throttle opening information, the vehicle returns to the
overdrive control mode again after the overdrive return timer is completed.
