PRECAUTIONS
1. Precautions concerning cruise control system
(1) When using the cruise control system, turn the cruise control system main switch (ON-OFF button) to ON after engine has started.
(2) When not in use of cruise control system, turn the cruise control system main switch (ON-OFF button) to OFF.
(3) Pay attention to vehicle speed while driving in declining lanes even if the cruise control system is active to control the vehicle speed.
(4) +(ACCEL)/RES(RESUME) operation changes according to the cruise control system conditions. When the cruise control system controls the vehicle speed, +(ACCEL) operates. When the cruise control system does not control the vehicle speed, RES (RESUME) operates.
(5) When the cruise control indicator turns off or turns yellow against driver’s intention, a malfunction of the cruise control function may be occurring.
(6) Do not use the cruise control system under the following road conditions.
·Roads where the certain vehicle distance is difficult to be maintained due to heavy traffic
·Steep downhill lanes
·Curving lanes with a sharp bend
·Frozen or snowy roads
·Slippery roads
·Steep downhill lanes
·Curving lanes with a sharp bend

DESCRIPTION OF FUNCTIONS
1. Cruise Control System
(1) This function is controlled by ECM, and operated by throttle body. ECM controls the following functions.
: ON-OFF, -(COAST)/SET, +(ACCEL)/RES (RESUME), CANCEL, vehicle speed operation
: ON-OFF, -(COAST)/SET, +(ACCEL)/RES (RESUME), CANCEL, vehicle speed operation
(a) ECM compares the vehicle speed detected by speed sensor and the vehicle speed memorized through the cruise control main switch. When the vehicle speed exceeds the stored vehicle speed, ECM commands the throttle motor of the throttle body to close the valve, on the other hand, when the vehicle speed is lower than the stored vehicle speed, ECM commands to open the valve.
(b) ECM receives signals such as ON-OFF, -SET, +RES, CANCEL through the cruise control main switch to execute these commands.
(c) When the system turns to ON through the cruise control main switch (ON-OFF button), the cruise control indicator in the combination meter ASSY turns green through ECM.
(d) When trouble occurs while driving with the cruise control function ON, the cruise control indicator in the combination meter ASSY turns off or turns yellow through ECM.
(e) When the cruise control main switch turns to -SET while driving, the cruise control SET indicator in the combination meter ASSY turns green through ECM to start the vehicle speed control.

2. Vehicle speed control
(1) Minimum speed
Possible minimum speed setting is approx. 40 km/h {25 MPH}. When vehicle speed is lower than the minimum speed, the cruise control system cannot be set. When the vehicle speed lowers under the minimum speed while the cruise control controls the vehicle speed, the speed control deactivates automatically, however the stored vehicle speed will be maintained.

3. Operation of the cruise control
(1) In addition to switching the cruise control system to ON/OFF, the cruise control main switch can operate the following seven functions.
: SET, -(COAST), TAP-DOWN, RES(RESUME), +(ACCEL), TAP-UP, CANCEL
: SET, -(COAST), TAP-DOWN, RES(RESUME), +(ACCEL), TAP-UP, CANCEL
(2) SET, -(COAST), TAP-DOWN activate with the switch down, while RES(RESUME), +(ACCEL), TAP-UP activate with the switch up.
(3) As the cruise control main switch is an auto return type switch, it is ON while operated in each arrowed direction, and OFF while not operated.
(a) SET control
When the cruise control main switch is in -SET while driving with the cruise control system in use (the cruise control indicator illuminates green), the vehicle speed is stored and the speed control starts.
When the cruise control main switch is in -SET while driving with the cruise control system in use (the cruise control indicator illuminates green), the vehicle speed is stored and the speed control starts.
(b) -(COAST) control
When the cruise control main switch is kept pressing to -/SET while the cruise control system is controlling the vehicle speed, the cruise control system sends the signal to ECM to operate the throttle valve motor of the throttle with the motor body ASSY, and then the throttle valve is closed. After this, when the cruise control main switch is released, the vehicle speed is stored and maintained.

SUBARU SELECT MONITOR
1. OPERATION
The on-board diagnosis function of the cruise control system uses Subaru Select Monitor. The on-board diagnosis function operates in two categories, which are used depending on the type of problems.
The on-board diagnosis function of the cruise control system uses Subaru Select Monitor. The on-board diagnosis function operates in two categories, which are used depending on the type of problems.
(1) Cruise Control Cancel Conditions Diagnosis:
·This category of diagnosis requires actual vehicle driving in order to determine the cause, as when cruise speed is cancelled during driving although cruise cancel condition is not entered.
·Cruise control memory in ECM stores the cancel code which occurred during driving. When there are multiple cancel code, they are shown on the Subaru Select Monitor.
·Cruise control memory in ECM stores the cancel code which occurred during driving. When there are multiple cancel code, they are shown on the Subaru Select Monitor.
CAUTION:
·In the cruise control memory, not only the cruise control “cancel” occurred (although the “cancel” operation is not entered by the driver), but also the “cancel” condition input by the driver is stored.
·The latest memory content (latest code) is cleared when ignition switch is turned to OFF. However, memory contents set by the diagnosis of faulty switches related to the system and cruise control will remain as trouble history (memory code) after the ignition switch is turned to OFF.
·The latest memory content (latest code) is cleared when ignition switch is turned to OFF. However, memory contents set by the diagnosis of faulty switches related to the system and cruise control will remain as trouble history (memory code) after the ignition switch is turned to OFF.

Circuit description
In addition to switching the cruise control system to ON/OFF, the cruise control main switch can operate the following seven functions. For SET, -(COAST), TAP DOWN, use -SET switch. For RES, +(ACCEL), TAP UP, use +RES switch. For CANCEL, use CANCEL switch. As the cruise control main switch is an auto return type switch, it is ON while operated in each arrowed direction, and OFF while not operated. When the inner contact of the cruise control main switch is turned on by the switch operation, the ECM reads the operating voltage for each switch.
