Although gasoline grades differ from one manu-

- If you must transport fuel in a fue l container, please note the following:

- Always place a fue l conta iner on the ground befo re filling . Never fill the fuel contai ner with fuel while it is in or on the vehicle. Elect rostatic charge can occur while refueling and the fuel vapo rs could

- Do not remove the engine cover under any

circumstances. This increases the risk of burns.

- If tests need to be performed with the en-

gine running, there is additional danger due

to moving components (such as the ribbed

belt, alternator and radiator fan) and from

the high-voltage ignition system.

- Do not under any circumstances give gas in-

advertently (for example, by hand from the engine compartment) if the vehicle is sta-

tionary but the engine is running and a gear

Ch e cking an d Filling

Using the prope r engine oil is important for the functionality and service life of the engine. Your engine was factory-filled with a high-quality oil which can usually be used throughout the entire year .

Note

Your Limited New Vehicle Warranty does not

cover damage or malfunctions due to failure to follow recommended maintenance and use requirements as set forth in the Audi Owner's

Manual and Warranty & Maintenance booklet .

- Use only a high quality engine oil that expressly complies with the Audi oil quality

standard specified for your vehicle's engine.

Using any other oil can cause serious engine

damage.

- Do not mix any lubricants or other additives into the engine oil. Doing so can cause en-

gine damage.

break-in period (see ¢ page 57) consume more

oil during th e break-in period than they consume

after oil consumption has stabilized. Under normal cond itions, the rate of oil con-

sumption depends on the quality and viscosity of the oil, the RPM (revolutions per minut e) at which the engine is operated, the amb ient tem-

perature and road condit ions. Further factors are the amount of oil dilution from water condensation or fuel resid ue and the oxidation level of the

oil. As any engine is subject to wear as mileage

builds up, the oil consumption may increase over time unt il repla cement of worn components may

become necessary. With all these variables coming into play, no

standard rate of oil consumption can be estab-

lished or spec ified . There is no alte rnative to reg-

@ Tips

If you need to add oil and there is none available that meets the Audi oil quality standard

your eng ine requires, you may add a total of

no more than 0.5 quart/li ter of a high-quality "synthet ic"oil that meets the following specifications.

- ACEA A3 or API SM with a viscosity grade of SAE OW-30, SAE SW-30 or SAE SW-40.

- Wear eye protect ion.

- To redu ce the risk of burns from hot eng ine oil, let the engine cool down to the touch.

- When remov ing the oil drain plug with your fingers, stay as far away as possib le. Always

- Drain the oil into a container designed for this purpose, one large enough to hold at

least the tota l amount of oil in your engine.

- Engine oil is poisonous. Keep it well out of

the reach of children.

- Continuous contact with used engine oil is

harmful to your skin. Always protect your skin by washing oil off thoroughly with soap and water.

Protect the vehicle battery against freezing if the vehicle wilt be parked for long periods of time so that it is not destroyed by "freezing"

9 page 164, Charging the vehicle battery .

Charging the vehicle battery

- A high ly explosive mixture of gases can form when charg ing batteries . Only charge the veh icle battery in well-ventilated areas .

- A drained vehicle battery can freeze at tem-

peratures around 32 QF (0 QC). A frozen or

thawed vehicle battery must not be charged

and must not be used anymo re. The battery housing can crack and batte ry acid can leak out if ice forms, which increases the risk of an explosion and chemical burns. Contact an authorized Audi dealer or authorized Audi Service Facility for more information.

- Do not connect or disconnect the charging

cable wh ile charging because this increases

the risk of an explosion .

To reduce the risk of lime scale deposits on the spray nozzles, use clean water with low amounts of calcium. Always add window cleaner to the water. When the outs ide temperatures are cold, an anti-freezing agent should be added to the water so that it does not freeze.

- The concent ration of anti-freezing agent

must be adjusted to the vehicle operating conditions in the respective climate. A concent rat ion that is too high can lead to vehicle damage.

- Never add rad iator anti-freeze or other additives to the washer fluid.

If you have changed the oil yourself, you must reset the oil change interval.
