On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunct ion Indicator Lamp (MIL) in the instrument cluster
=>
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e warning/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
whi le you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected.
Contact your authorized Aud i dealer .
If the light illuminates, the electronic speed limiter may also be
malfunction ing. For more information=>
page 22, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to

• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicle s
in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has

Natural leather
Audi makes great efforts to maintain the properties,
natural look and feel of interior leather.
General
We offe r many different types of leathe r on our veh icles. Most are
different types of nappa leather, which has a smooth surface and
comes in various colors.
Th e intensity of the colo r determines the visual cha racteristics and
appearance. If the surface of the leather has a typica l natural look,
then the leather is a nap pa leather that has been left in a relatively
natural condition. This leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect bites, skin folds, and
subtle variations in color remain visible. These characteristics demon­
strate that the mater ial is natu ral.
Natural nappa leather is not covered by a color finish. It is therefore
more sensitive to soiling and wear, which is something you need to ..,_

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoothly and reliably. Choosing the right oil and changing oil
within the time and mileage intervals printed in your vehicle 's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
that will help assure that your vehicle 's engine will get the lubrication
it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine lubri­
cation that can outlast traditional petroleum-based oils, making
them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petroleum-based engine oil, the oil that
you use must conform to Audi's oil quality standard VW 502 00 to
help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits , sometimes called "sludge", that
over time can lead to expensive repairs.
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil. To help prevent the formation of harmful deposits
use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina­
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W -30 or SAE OW -40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail­
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica­
tions is available - may you top off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE 5W-
40, SAE SW-30, or SAE OW-40 . However, during the entire time
between oil change intervals, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that has been approved for
your vehicle, 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 old engine oil can reduce engine performance and can
lead to expensive engine repairs.
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 Advisor .
Under some circumstances the engine oil should even be changed
more 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 below freezing point 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 essential that you change your 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 failure 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. •
Safety first
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
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
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
engine 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 variables 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 284. Top off the oil at your earliest convenience~ page 285.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine

& WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=>
page 338, fig. 254 and
=> page 338, fig. 255.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen, for
example, when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of
gravity. Otherwise , the vehicle might tilt or slip off the hoist ,
causing serious personal injury.
0 Note
• B e aw are of the following poi nts b efo re li fting the ve hicl e:
- The vehicle should never be lifted or jacked up from under­
neath the engine oil pan, the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist.
- Before driving over a workshop hoist, ensure that there is
sufficient clearance between the hoist and low parts of the
vehicle. •
