The Holden Colorado ran across two quite different generations, so picking the right manual means matching your build year and series, not just the model name. This guide explains how to choose between the RC and RG manuals, what the owner manual and service booklet each cover, and where to look for the service schedule, service reminder reset and fault codes. Browse and download from the Holden Colorado manuals page.
Quick answer
- Find your build year on the compliance plate, then match it to the manual year.
- RC Colorado (2008–2012) is the Isuzu-derived first generation; RG (2012–2020) is the GM Duramax generation.
- The owner manual covers operation, warning lights and basic maintenance; the service and warranty booklet covers the service schedule.
- If the build year sits on a generation changeover, confirm the series on the plate before downloading.
RC vs RG: which generation is yours
| Series | Years | Engine | Notes |
|---|---|---|---|
| RC Colorado | 2008–2012 | 3.0L Isuzu 4JJ1 turbo-diesel; 2.4L petrol; 3.6L Alloytec V6 petrol | Isuzu-derived first generation; replaced the RA Rodeo in 2008. |
| RG Colorado | 2012–2020 | 2.8L Duramax turbo-diesel | All-new GM-designed truck; 2016/17 facelift sometimes called RG II. |
Because the RC and RG are mechanically different trucks, their manuals are not interchangeable. The RC diesel is an Isuzu engine; the RG 2.8 Duramax is not, so service and engine sections differ. If you are ordering parts, confirm the series first — see the Colorado VIN and compliance plate guide.
Manuals available by year
The Colorado manual library covers model years 2008 through 2020. For most years there are two documents:
- Owner’s manual — day-to-day operation, controls, warning lights, fluids and owner-level maintenance.
- Service and warranty booklet — the service schedule and warranty terms.
Match the document year to your build year. Where a year offers more than one file, the owner’s manual is the thicker operation guide and the service and warranty booklet is the slimmer maintenance document. Open the Colorado manuals page to download the year you need.
Service schedule, service reset and fault codes
Owners often come here looking for three specific things:
- Service schedule. The service and warranty booklet for your year lists the official service intervals. Intervals changed across the RC and RG, so use the booklet that matches your build year rather than a generic figure.
- Service reminder reset. The RG shows a service reminder in the driver information display. The owner’s manual for your year describes the reset procedure; it is a dash-menu and button sequence, and the exact steps vary by year and trim, so follow the manual for your build.
- Fault codes. Dashboard warning lights are explained in the owner’s manual. Stored diagnostic trouble codes need a scan tool to read; the manual explains what each warning light means but not the full code list.
If a fault relates to a part you need, send the warning details with your enquiry on the Colorado parts page.
