tance .
(I] Tips
• To avoid adversely affecting heating and cooling performance and
to prevent condensation on the windows, the air intake in front of the
w indshield must be free of ice, snow and leaves.
• Th e air flowing out of the vents and througho ut the veh icle's
entire inter ior is discharged at the rea r of the vehicle . Make su re that
the o utlet s lots are not covered by clothing, etc.
• Climate control works most effective ly if the windows and the
panoramic sliding/tilt ing sunroof * are closed. However, if the interior
of a parked vehicle is extremely hot from the sun, briefly opening the
windows can speed up the cooling process. •

Trailer towing
"-------------------------------------------------
Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 252.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance is up to the additional load. Make
sure that the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack in the chains to permit
turning corners. When you install safety chains, make sure they will
not drag on the road when you are driving.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,

For more information about engine oil that has been approved for
your veh icle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa .com or www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform to
Audi oil standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet . Do not exceed these intervals - harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repa irs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Adviso r.
Under some circumstances the engine o il should even be changed
more frequent ly. Change oil more often if you drive mostly short
distances, operate the veh icle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freez ing po int for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. 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 essentia l that you change yo ur oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to fa ilure 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 Service or Repair Orders that all scheduled maintenance
was performed in a timely 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 comb ustion eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 246) consume
more oil dur ing 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 oxidation 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 level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as possible
~ page 279. Top off the oil at your earliest convenience~ page 279.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNINGS ~
& in "Working in the engine
compartment" on page
275.

& WARNING (co ntinued )
• When removing the oil drain plug w ith your fingers , sta y as far
away as possible . Alway s keep your forearm parallel to the ground
to help p revent hot oil from running down your arm.
• Drain the oil into a container de signed for this purpose, one
large enough to hold at least the total amount of oil in your
engine .
• Engine oil is poisonous. Keep it well out of the reach of chil­
dren.
• Continuous contact with u sed engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.
0 Note
N ever mix o il additives wi th you r engine oil. These a dditives can
damage your engine and adversely affect your Audi L imited New
Vehicle Warranty.
ffi For the sake of the environment
• Before changing your oil, first ma ke s ure you know w here yo u can
prope rly dispose of the used o il.
• Always dispose of used engine oil properly . Do not dump it on
garden so il, wooded areas , into open streams or down sewage drains .
• Recy cle used e ngine o il by taking it to a used eng ine oil colle ction
facili ty in your area, or contact a service statio n.•
Safety first
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engi ne f rom over heat in g and it prote cts the engine fro m
free zing in the winter .
The coo ling system is sealed and generally requires little attention.
Th e cool ing sys tem h as been filled a t the f actory w ith a permanent
coo lant wh ic h does not need to be changed . The coolant consists of a
mi xtu re of water and the manufacturer 's glyco l-basedcoo lant add i­
t ive Gl2++ antifreeze w ith anticor ros ion addit ives (50% for USA
mode ls ; 60% for Ca nadian mode ls). This mixture both ass ures the
necessa ry frost protect ion and p rotects meta l components in the
engine's cooling system from corrosion and scaling. It also raises the
boiling poin t of the coo lant.
Do not red uce the concentrat io n of the coolant in t he summer by
adding p lain wate r. The proportion of coolant additive must be at
least 50 % but not more than 60 %
to maintain antifreeze protection
and coolin g efficiency. If the coolan t fros t pro tection is too low , the
coo la nt cou ld freeze and damage t he veh icle heat ing and engine
cooling system .
For year-ro und d riving, a ntifree ze is adde d at the fac to ry fo r tempe r­
atures down to:
• - 31°F(-3 5°C) USA
• -40°F ( -40°() Canada.
Yo u can mix the Gl2 ++ coo lant add itive with other additives (G12 + or
Gl2) . A lways check wi th yo ur auth o rized Audi dealer .
