Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage=:> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area=>& .
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
Safety first
& WARNING (continued)
• Move selector lever to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire. • Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch:
-Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running:
- First, fully apply the parking brake, move selector lever to
"P" (Park). .,

Changing the engine oil
The engine oil and oil fi lter must be changed according to the mileage
(kilometers) and t ime intervals specified in your vehicle 's Warranty
&
Maintenance booklet . Do not exceed these interva ls -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repairs .
Changing the oil at the recommended intervals is so very impo rtant
because the lubricating properties of o il decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the engine oil should even be changed
mo re frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay be low freezing point for long periods.
Detergent addit ives in the oi l wi ll make fresh oil look dark after the
engine has been running for a short t ime. This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oi l that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to fai lure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner 's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Serv ice or Repair Orders that all scheduled maintenance
was performed in a time ly manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the lif e of the engine. Typically,
engines with a specified break- in period (see~
page 251) consume
more oil during the break-in period than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the ox idation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil leve l warning symbol in the instrument
cl uster lights up, you should chec k the oil level as soon as possible
with the oil dipstick~ page 283. Top off the oil at your earliest
convenience ~
page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on
page 279.

0 Note
Driv ing with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead , check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip .
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult your Audi dealer to
have the cause of you r concern properly diagnosed. Keep in mind that
the accurate measurement of oil consumpt ion requires great care
and may take some time . Your Audi dealer has instructions about how
to measure oil consumption accurately .•

Determining oil level
-Park your vehicle so that it is horizontally level.
- While at operating state temperature, briefly let the
engine run at idle and then shut it off.
- Wait approx. two minutes.
Pull out the oil dipstick. Wipe off the oil dipstick with a
clean cloth, and slide it back in as far as it will go .
- Pull it back out and read off the oil level ::::> fig. 208 or
~ fig. 209. Top off the engine oil, if applicable
~ page 284.

The oil level needs to be checked at regular intervals . The best times
to do this are whenever you refuel and prior to long trips.
Depending on the way the vehicle is driven and the operating condi­
tions, oil consumption can be up to 1 quart per 1.200 miles
(l liter
per 2,000 km). Consumption may be higher within the first 3 ,000
miles (5,000 km) .•

page 279.
-Unscrew the cap => fig. 210.
- Carefully top off with the appropriate oil in 0.5 liter doses.
- Check the oil level again after two minutes=>
page 283.
-Top off the oil again, if necessary . -
Screw the cap back on the filling hole and slide the oil
dipstick in as far as it will go.
& WARNING
• While topping off, the oil must not come in contact with hot
engine parts -fire hazard!
• The oil filler cap must be properly secured to prevent oil from
being sprayed on the hot engine and ex haust system when the
engine is running -fire hazard!
• If your skin has come in contact with the engine oil, you must
subsequently cleanse it thoroughly.
0 Note
• The oil level must not be above range@- danger of converter or
engine damage! Contact an authorized dealership to draw off oil, if
necessary .
• Audi does not recommend the use of oil additives. They may
damage the engine and adversely affect your New Vehicle
Warranty.
• Under no circumstances can the oil come in contact with the
sewage network o r the soil.
• Observe and follow legal regulations when disposing of empty oil
containers. •

Ill Tires and wheels
-------------------
Winter tires lose their effectiveness when the tread is worn down to
a d epth o f 0. 157 inch ( 4 mm).
Only drive w it h w inte r tir es under w inte r co nd it io ns. S u mmer t ires
hand le better w hen there is no s now or ice on t he roads a nd the
t em pe ra ture i s above 4 5
°F (7 ° ( ).
If you have a flat tire, see notes on spare wheel~ page 307.
Please always remember that winter tires may have a lower speed
rating than t he t ires originally installed on yo ur ve hicle at the time it
was ma nufact ured . Please see~
page 309, "Speed rat ing ( letter
c ode)" fo r a listing of the speed rating le tte r codes a nd t he maximu m
speed at which the tires can be dr ive n.
Th e spee d rat ing le tt er code( ~
page 298 ) is on the side w all of the
t ire~
page 307 .
& WARNING
Winter tires have ma ximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed perm itted fo r
your specific winter tires . This will cause damage to the tire s
leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were des igned can cause ti re failure includ ing a
blowout and sudden deflation, lo ss of control, crashes and serious
personal injuries . Have worn or damaged tires replaced immedi­
ately.
• Winter t ires have maximum speed rat ing that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic conditions.
Never let the good acceleration of the winter tires and all-wheel
drive tempt you into taking extra risks. Always remember :
• When braking , an all-wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions.
Use s ummer tires when weather co ndit io ns permit. They are qu ieter,
do not wear as quickly and reduce fuel consum ption .•
Snow chains
Snow chains may be fit te d on ly to the fr ont w heels, and only to
certain t ire sizes . Ask yo ur aut horized Audi dealer on which tire sizes
snow chains can be used .
If you are go ing to use snow c ha ins, then you must insta ll th em on t he
front wheels at least .
Th e sn ow chain s mus t have low-pr ofile li nks and m ust no t be th icker
than 0 .53 inc h (13.5 mm), including the lock.
R emove wheel cente r covers an d trim discs before putti ng snow
chains on your vehicle~
0. For safety reaso ns cove r caps m ust the n
be fitted over the whee l bo lts. These are availab le from a utho rized
Audi dealers.
& WARNING
Using the wrong snow chains for your veh icle or installing them
incorrectly can incre ase the risk of loss of control leading to
serious personal injury .
