WARNING

If the air intake duct is removed from the throttle body take great care to keep fingers away
from the throttle plate. The drive motor has very high torque and is capable of random move-
ment at any time. Do not under any circumstances activate the throttle plate by hand.
When removing the throttle body from the intake manifold disconnect the wiring first. During
replacement connect the wiring last.
Do not activate the throttle body using a DC suppy to test the motor,as permanent damage to
the throttle body will result.

ON-VEHICLE SERVICE

AUTO-CRUISE CONTROL SWITCH CHECK

M1172001200054

AUTO-CRUISE CONTROL MAIN SWITCH CHECK

1. Turn the ignition switch to the "ON" position.
2. Check that the "CRUISE" indicator lamp within the

combination meter illuminates when the "CRUISE" (MAIN)
switch is switched "ON".

AUTO-CRUISE CONTROL SETTING

1. Switch "ON" the "CRUISE" (MAIN) switch.

2. Drive at the desired speed, above approximately 40 km/h.
3. Push the auto-cruise control switch in the direction of the

arrow.

4. Check to be sure that when the switch is released the speed

is the desired constant speed.

NOTE: If the vehicle speed decreases to approximately 15
km/h below the set speed because of climbing a hill for
example, it is normal for the auto-cruise control to be can-
celled.
