Please drive to warm up engine

Note

Especially low outside temperatures are a main

reason why fuel may get into the engine oil. The

fuel can only evaporate from the engine oil if the

engine oil temperature is high enough.

If the engine oil level is too low or too high,

there is a risk of engine damage.

Tips

The oil level indicator in the display is only an

informational display. If the oil level is too

low, a minimum oil warning appears in the in-

strument cluster. Add oil and close the hood.

The current oil level will be displayed on the

MMI the next time the ignition is turned on.

Drive in the “S” position.

Drive the engine at higher RPMs while avoiding

full acceleration.

You should drive for at least 30 minutes. The in-

dicator light may not turn off during this time.

Repeat the steps that are described at any time.

Tips

Have an authorized Audi dealer or authorized

Audi Service Facility repair the malfunction if the

indicator light does not turn off after a few

drives.

The engine oil consumption may be up to

0.5 quart/600 miles (0.5 liter/1,000 km), de-

pending on driving style and operating condi-

tions. In RS models, the oil consumption may

be up to 0.8 qt/600 mi (0.8 L/1,000 km).

Consumption may be higher during the first

3,000 miles (5,000 km). The engine oil level

must be checked regularly. It is best to check

each time you refuel your vehicle and before

long drives.

WARNING

When the message  Please drive to warm

up engine appears, adjust your speed accord-

ing to the weather, road, terrain, and traffic

conditions. You should never disobey the traf-

fic laws applicable in the country in which you

are driving in order to follow driving recom-

mendations.

– Because of the lubrication and cooling of

the engine, combustion engines consume

oil. The oil consumption varies depending

Checking and Filling

on the engine and may change during the

service life of the engine. Engines generally

consume more oil at the beginning during

the break-in period. Then oil consumption

stabilizes after the break-in period.

Adding engine oil

– Under normal conditions, oil consumption

depends on the quality and viscosity of the

oil, the engine RPM, the climate conditions,

and the road conditions. The dilution of oil

from condensation or fuel residue as well as

the age of the oil also play a role. Because

engine wear increases with mileage, oil con-

sumption will increase again over time until

it may be necessary to replace worn compo-

nents.

Observe the safety precautions ðpage 255, Gen-

eral information.

– Because all these variables play a role, it is

not possible to define an oil consumption

standard. Therefore, the oil level must be

checked regularly.

– If you believe that your engine has increased

its oil consumption, contact an authorized

Audi dealer or authorized Audi Service Fa-

cility to determine the cause. Please note

that an exact oil consumption measurement

must be done with the necessary care and

accuracy and may take time. An authorized

Audi dealer or authorized Audi Service Fa-

cility is trained in accurately measuring the

oil consumption.

engine oil capacities for the USA at

or for Can-

customer-area/care-and-maintenance/

, or call

800-822-2834.

WARNING

– When adding oil, do not let oil drip onto hot

engine components. This increases the risk

of a fire.

– You must close the cap on the oil filler open-

ing correctly so that oil does not leak out on-

to the hot engine and exhaust system when

the engine is running, because this is a fire

hazard.

– Always clean skin thoroughly if it comes into

contact with engine oil.

– Engine oil is poisonous and must be kept out

of reach of children.

– Store the engine oil securely in the original

container.

Checking and Filling

If you change the engine oil yourself, please note

the following important information:

Note

– Only use high-grade engine oil that explicit-

ly meets the Audi oil quality standard for

your vehicle. Using another oil may cause

severe vehicle damage.

WARNING

If you change the engine oil on the vehicle

yourself, the following precautions must be

followed:

– Do not mix any additives with the engine oil.

Additives may cause engine damage that is

not covered by your New Vehicle Limited

Warranty.

– Wear protective eyewear.

– Due to the risk of scalding, allow the engine

to cool down sufficiently.

– Maintain enough distance when you are re-

moving the oil drain plug. While doing this,

keep your forearm parallel to the ground to

reduce the risk of hot oil dripping down your

arm.

For the sake of the environment

– Oil should never enter the sewer system or

come into contact with the ground.

– Follow the legal regulations in the country

where you are located when disposing of

empty oil containers.

– Drain the oil into a container designed for

this purpose that is large enough to hold the

full amount of oil in your engine.

– Engine oil is poisonous. Always store out of

reach of children.

Changing engine oil

Audi recommends having the oil changed at an

authorized Audi dealer or authorized Audi Serv-

ice Facility.

– Prolonged contact of used engine oil with

the skin may cause skin damage. Always

wash oil off immediately with soap and wa-

ter to protect your skin.

Observe the safety precautions ðpage 255, Gen-

eral information.

Note

The engine oil must be changed at the intervals

specified in the Warranty & Maintenance Book-

let. This is very important because the lubrication

function of the oil gradually declines during regu-

lar vehicle operation.

Do not mix any additives with the engine oil.

Additives may cause engine damage that is

not covered by your New Vehicle Limited War-

ranty.

The engine oil should be changed more frequent-

ly under certain circumstances. Have the oil

changed more frequently if you often drive short

distances, your vehicle is predominantly in stop-

and-go traffic situations, is in very dusty environ-

ments, or is operated for long periods of time in

temperatures below zero.

For the sake of the environment

– Before changing the engine oil, make sure

you can dispose of the used engine oil cor-

rectly.

– Engine oil must always be disposed of cor-

rectly. Do not dump it in the yard, in the for-

est, or in open water, river channels, or sew-

ers.

Cleansing additives in the oil make fresh oil ap-

pear darker after the engine has run briefly. This

is normal and no reason to change the engine oil

more frequently than recommended.

– Have your used engine oil recycled by bring-

ing it to a used oil collection site or contact

a gas station.

Because correctly disposing of engine oil is diffi-

cult and special tools and technical knowledge

are needed for an oil change, Audi recommends

having your engine oil changed by an authorized

Audi dealer or authorized Audi Service Facility.
