Subaru Service FAQ

Subaru Service FAQ


You have questions; we have answers. Many times, you need a quick response to a question you suspect is pretty standard. That's what this page is for. We've gathered some of our most commonly addressed questions here for you. There are a ton of other great resources available, and an area that is most widely over-looked is your Subaru owners manual that is supplied with your vehicle, here you will find little hints and tips that will make your drive a little more relaxed.

If there is a specific servicing question that you still find yourself needing answers to, we invite you to give our servicing team a call at (02) 4648 1508. We are more than happy to help, and can even schedule a service appointment for you if you'd like.

Q: What should I do if my Check Engine Light comes on and why does my cruise light flash?

A: Well it depends. Many sensors provide information to your vehicle computer to monitor performance with your vehicles fuel system including combustion efficiency, exhaust performance and even oil level that can all trigger a Check Engine Light. A solid Check Engine Indicator is usually a minor concern that should be looked at when it's convenient to visit our Service Centre next. A flashing light is pretty rare, but we do see it sometimes. The error may indicate a critical condition that should be repaired right away. We would recommend that the vehicle has limited driving to prevent damage to a significant component. Cars that have electronic throttle will generally see a flashing Cruise Control Light If a Check Engine Indicator comes on. This occurs because the vehicle's computer is also responsible for Cruise Control Operation and the engine computer cannot decipher whether the current fault could affect the electronic throttle control hence it is disabled until the ongoing failure is fixed and the system error cleared.

Q: What is the blue light on my dash when my car is first started?

A: Most new model variant vehicles do not have a temperature gauge, and therefore the Blue light indicates that your engine is cold & not yet at optimum operating temperature. As your engine warms up, the fluids circulate better and everything stabilizes & the Blue light will extinguish. To minimize the wear on your engine and drive-train components, during this period we advise retaining from aggressive driving.

Q: Why does my car idle fast when it first starts?

A: Today, vehicle manufacturers are facing more stringent environmental regulations to reduce pollutants that are emitted from the vehicles exhaust system. By retarding the engines camshaft timing on startup, this, in turn, activates the catalyst within the exhaust system lowing pollutants early. However, by doing this the engine torque is reduced and therefore faster then "what is considered normal" is used as a countermeasure for torque down that would generally result in unstable engine idle.

Once the engine is above a certain coolant temperature, the engine idle is lowered to what most people would consider a normal idle speed.

Q: How do I properly check my oil?

A: In your engine compartment you'll see a yellow dipstick with a small engine oil icon on it. With your engine cold before driving it and on a level surface, remove the dipstick and wipe off any oil on a rag or paper towel. Insert the dipstick again, remove it and examine where the oil comes to on the bottom of the dipstick. It should be in the "normal" range printed on the metal of the dipstick.

Q: What is the recommended Tyre pressure for my car?

A: The manufactures recommended pressure is found on the tyre placard on the drivers "B" Pillar. This can be viewed when opening the driver's door.

I think it is important to remember that the recommended factory settings are determined by the engineers using a plot graph method. This simply means, how the specific tyre behaves in various road conditions i.e. stopping distance, vehicle handling, cabin noise, fuel consumption etc. As you can see with the few things I have listed that tyre life is not mentioned, although it would be there somewhere lower on this list. With most vehicles that we see come through our mechanical workshop division generally most customers tyres present as "under-inflated". 

To identify a tyre that is underinflated, one would see the tyre wearing more aggressively on both the inner and outer edges with the centre of the tyre in better condition.

The other common condition that we see is "left-hand front" Outerwear. This condition does not automatically mean the vehicle has an alignment issue although it could be possible. We again tend to see a combination of under-inflated tyres. So under-inflation combined with excessive tyre roll due to the car park and roundabout cornering will, in turn, cause this type of wear.

Our recommended guide for most Subaru vehicles is to increase the front "steering" tyres to between 37 - 38 (psi) or 248 - 262 (kpa) subject to drivers ride comfort discretion, and the rear tyres (with normal carrying loads) inflated between 35 - 36 (psi) or 241 - 248 (kpa)

This pressure will help with increased service life and also keep the tyres close to manufactures specification should the tyre pressures not be checked between service intervals.
