8B-2 CRUISE CONTROL SYSTEM
General Description
The cruise control keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received.
W hen the main switch “AUTO CRUISE” is turned on with the vehicle in the running mode, the battery voltage is
applied to the control unit (Engine control module). W hen a signal from the control unit while the vehicle is in this
state, the cruise control actuator is activated to operate the system. Also, while the system is operating, the cruise
control set indicator light in the meter assembly lights up.




RTU7Z0SH019601

1. SET/COAST Switch Function
1. Set Function: W hen the SET/COAST switch is pressed and released with the main switch on, the speed at
which the vehicle is running at that moment is stored in the memory, and the vehicle automatically runs at the
stored speed.
2. COAST-down Function: W hen the SET/COAST switch is kept on while the vehicle in running, the vehicle
decelerates during that time. The speed at which vehicle is running when the control switch is pressed in the
memory, and the vehicle automatically returns to the stored speed.
3. Tap-down Function: W hen the SET/COAST switch is pressed and released instantaneously while the
vehicle is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the
vehicle was running when the SET/COAST was released last is stored in the memory, and the vehicle
automatically returns to this stored speed.

2. RESUME/ACCEL Switch Function
1. Resume Function: W hen the RESUME/ACCEL switch is turned on/off after the system is temporarily
deactivated by pressing the brake or clutch pedal while the vehicle is running, the vehicle resumes the speed
stored before the system was released, and the vehicle automatically runs at the stored speed.
2. Accelerate Function: W hen the RESUME/ACCEL switch is kept on the vehicle accelerates its speed during
that time. The vehicle speed at which the vehicle was running when the switch was turned off is stored in the
memory, and the vehicle automatically returns to this speed.
3. Tap-up Function: W hen the RESUME/ACCEL switch is turned on and off instantaneously while the vehicle
is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the vehicle
was running when the switch was turned off last is stored in the memory, and the vehicle automatically
returns to this stored speed.

Cruise Control – HFV6 Page 8C–3
1 General Information
A new cruise control system has been introduced due to changes in the powertrain architecture and components. There
is no longer a cruise control module; instead the management has been taken over by the engine control module (ECM).
To the user, the system operates as previously, with all controls from the cruise control switch assembly and the cruise
control messages presented by the instrument cluster. For vehicles fitted with the HFV6 engine refer to 1.3 System
Operation .

The cruise control system now has an
additional fail-safe feature. The brake pedal
must be pressed in the ignition cycle for the
cruise control to be engaged. The cruise
control will not engage until this is done.
1.1 WARNINGS, CAUTIONS and NOTES
This Section contains various W ARNINGS, CAUTIONS and NOTE statements that you must observe carefully to reduce
the risk of death or injury during service, repair procedures or vehicle operation. Incorrect service or repair procedures
may damage the vehicle or cause operational faults. W ARNINGS, CAUTION and NOTE statements are not exhaustive.
GM HOLDEN LTD can not possibly warn of all the potentially hazardous consequences of failure to follow these
instructions.
Definition of WARNING, CAUTION and NOTE Statements
Diagnosis and repair procedures in this Section contain both general and specific W ARNING, CAUTION and NOTE
statements. GM HOLDEN LTD is dedicated to the presentation of service information that helps the technician to
diagnose and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard
to the technician if they are not followed in the recommended manner. W ARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from occurring, but not all hazards can be foreseen.
WARNING Defined
A W ARNING statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in death or injury. A WARNING statement alerts you to take necessary action or not to take a
prohibited action. If a W ARNING statement is ignored, the following consequences may occur:
• Death or injury to the technician or other personnel working on the vehicle,
• Death or injury to other people in or near the workplace area, and / or
• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION Defined
A CAUTION statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equipment, or corruption of data. If a CAUTION statement is ignored,
the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,
• Faulty operation or performance of any system or component being repaired,
• Damage to any system or components which depend on the proper operation of the system or component being
repaired,
• Faulty operation or performance of any systems or components which depend on the proper operation or
performance of the system or component under repair,
• Damage to fasteners, basic tools or special tools and / or
• Leakage of coolant, lubricant or other vital fluids.
