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.
NOTE Defined
A NOTE statement immediately precedes or follows an operating procedure, maintenance practice or condition that
requires highlighting. A NOTE statement also emphasises necessary characteristics of a diagnostic or repair procedure.
A NOTE statement is designed to:
• Clarify a procedure,
• Present additional information for accomplishing a procedure,
• Give insight into the reasons for performing a procedure in the recommended manner, and / or
• Present information that gives the technician the benefit of past experience in accomplishing a procedure with
greater ease.

2 Maintenance Operations
2.1 Transmission Fluid
When adding or changing the transmission fluid, use only the recommended automatic transmission fluid, refer to
0B Maintenance and Lubrication.
For the automatic transmission fluid diagnosis, refer to 7C3 Automatic Transmission – 4L60E – Hydraulic and
Mechanical Diagnosis.
Transmission Fluid Colour
New transmission fluid is red in colour due to a dye that is added to the fluid so it can be distinguished from other oils and
lubricants. The red dye is not permanent and as such, is not an indicator of the quality of the fluid.
As the vehicle is driven the transmission fluid will quickly look darker in colour and appear to be a light brown. A dark
brown colour with a distinctively burnt odour may indicate fluid deterioration and the need for fluid replacement.
NOTE
A dark brown fluid colour observed, coupled with
a reported delayed shift pattern may only indicate
that fluid replacement is required. This is not a
definite indication of a potential transmission
failure.
Transmission Fluid Level
NOTE
Carry out this operation with the transmission at
normal operating temperature (82 – 94°C), as the
temperature greatly affects the fluid level.
1 Drive the vehicle for a distance of at least 25 km to bring the transmission up to normal operating temperature.

If the transmission is not at normal operating
temperature and the correct procedure is not
followed, the result could be a false reading of
the fluid level on the transmission fluid
indicator.
2 If the vehicle has been operated under any of the following conditions, switch the engine off and allow the transmission to cool for approximately thirty minutes:
• in high ambient temperatures above 32° C,
• at sustained high speeds,
• in heavy stop / start city traffic during hot weather, or
• towing.
3 Park the vehicle on level ground.
4 Move the gear selector to the Park position and apply the park brake.
5 Allow the engine to idle for 3 minutes with the accessories turned off.

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.
