Spongy brake pedals, increased pedal travel, fluid leaks or components seizing may mean your brake fluid needs changing. Brake fluid deteriorates over time as it absorbs moisture from the air. Once contaminated it lowers the fluid's boiling point and corrodes internal brake system components. Changing fluid regularly avoids these problems and helps to flush contaminates out of the hydraulic system.
Check air pressure weekly (including spare) to ensure safety, reduce fuel consumption and increase tyre life. Correct air pressures are shown on the tyre placard located in the driver's door. Do not attempt to drive on a flat tyre more than is necessary to safely stop. Driving even short distances may cause irreparable damage. Tyres should be replaced when:
- Cord or fabric is showing or tread indicators appear. Tread indicators appear as plain bars when only 1.5mm of tread remains.
- Tread or sidewall is cut, split or cracked and exposes fabric.
- Tyre has a bump or bulge in it.
- Tyre has a puncture which cannot be repaired because of size or location of damage.
The front and rear tyres wear out at different rates. Rotating your tyres will extend the life of your tyre tread and help avoid the problem of poor directional stability.
Levels should be checked weekly. Check level when the oil is warm, or when stopping for fuel. Use only specified, recommended grades of oil outlined in the handbook. Oil that is too thin (low viscosity) will increase its consumption, so stick to specified grades. The use of supplemented additives that are not specified in your handbook is not recommended as they will not only increase operating costs but also may be detrimental to the operation of your vehicle.
Coolant levels should be checked at least weekly. If required, top up coolant, mixing a solution of Holden coolant and clean fresh water as per the ratio specified in your handbook. It must be diluted to the correct dosage. Do not top up coolant level beyond the maximum mark. Never mix incompatible coolants. In an emergency use plain water until the correct coolant is available. Have your cooling system periodically checked by a trained technician. If you find you're having to top up the cooling system more than every two weeks, see your Holden Dealer.
Washer Fluid Levels
Check and top up washer fluid weekly. For best results, add the correct amount of Holden washer fluid, as specified in your handbook.
When fitted, air conditioning uses power from the vehicle's engine, so you will notice a small decrease in power and a slight increase in fuel consumption when it is in use. Switch air-conditioning on for 5-10 minutes once every two weeks (even in winter) to lubricate the air-conditioner system seals. A slight hissing sound may be heard for a short time when air is turned off - this is normal.
Ethanol and your Holden vehicle
Holden vehicles manufactured since 1986 will operate satisfactorily on E10. However, some vehicles manufactured by others and branded as Holdens do not operate satisfactorily on E10 fuel.
Vehicles that do not operate satisfactorily on E10 fuel are:
Apollo (1/87-7/89), Nova (2/89-7/94), Barina (1985-1994), Drover (1985-1987), Scurry (1985-1986), Astra (1984-1989), Astra SRi 2.2L (11/2006 onwards), Astra 2.2L Twin Top Convertible (11/2006 onwards).
Please refer to the vehicle's Owner's Manual for recommended fuel usage.
