Toyota Yaris: Do-it-yourself service precautions - Introduction - Do-it-youself maintenance - Toyota Yaris XP90 2005–2010 Owner's ManualToyota Yaris: Do-it-yourself service precautions

If you perform maintenance by yourself, be sure to follow the correct procedure given in this Section.

You should be aware that improper or incomplete servicing may result in operating problems.

Performing do-it-yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Toyota Warranty statement for details and suggestions.

This section gives instructions only for those items that are relatively easy for an owner to perform. As explained in Section 6, there are still a number of items that must be done by a qualified technician with special tools.

For information on tools and parts for do- it-yourself maintenance, see “Parts and tools”.

Utmost care should be taken when working on your vehicle to prevent accidental injury. Here are a few precautions that you should be especially careful to observe:


When the engine is running, keep hands, clothing, and tools away from the moving fan and engine drive belts. (Removing rings, watches, and ties is advisable.) Right after driving, the engine compartment—the engine, radiator, exhaust manifold and spark plug boots, etc.—will be hot. So be careful not to touch them. Oil, fluids and spark plugs may also be hot.

If the engine is hot, do not remove the radiator cap or loosen the drain plugs to prevent burning yourself.

Do not leave anything that may burn easily, such as paper or rags, in the engine compartment.

Do not smoke, cause sparks or allow open flames around fuel or the battery. Their fumes are flammable.

Be extremely cautious when working on the battery. It contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack supporting it. Always use automotive jack stands or other solid supports.

Be sure that the ignition is off if you work near the electric cooling fans or radiator grille. With the ignition on, the electric cooling fans will automatically start to run if the engine coolant temperature is high and/or the air conditioning is on.

Use eye protection whenever you work on or under your vehicle where you may be exposed to flying or falling material, fluid spray, etc.

Used engine oil contains potentially harmful contaminants which may cause skin disorders such as inflammation or skin cancer, so care should be taken to avoid prolonged and repeated contact with it. To remove used engine oil from your skin, wash thoroughly with soap and water.

Do not leave used oil within the reach of children.

Dispose of used oil and filter only in a safe and acceptable manner.

Do not dispose of used oil and filter in household trash, in sewers or onto the ground. Call your dealer or a service station for information concerning recycling or disposal.

Take care when filling the brake and clutch fluid reservoirs because brake fluid can harm your eyes and damage painted surfaces. If fluid gets in your eyes, flush your eyes with clean water immediately. If you still feel uncomfortable with your eyes, go to the doctor.


Remember that battery and ignition cables carry high currents or voltages.

Be careful of accidentally causing a short circuit.

Add only “Toyota Super Long Life Coolant” or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology to fill the radiator. “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water (for the U.S.A.) or 55% coolant and 45% deionized water (for Canada).

If you spill some of the coolant, be sure to wash it off with water to prevent it from damaging the parts or paint.

Do not allow dirt or anything else to fall through the spark plugholes.

Use only spark plugs of the specified type. Using other types will cause engine damage, loss of performance or radio noise.

Do not reuse iridium-tipped spark plugs by cleaning or regapping.

Do not overfill automatic transmission fluid, or the transmission could be damaged.

Do not drive with the air cleaner filter removed, or excessive engine wear could result. Also backfiring could cause a fire in the engine compartment.

Be careful not to scratch the glass surface with the wiper frame.

When closing the engine hood, check to see that you have not forgotten any tools, rags, etc.
