Introduction
General notes
The driver information display inside the instrument
cluster provides you, the driver, with important informa­
tion.
F ig. 7 In st rum ent
c luster : center d is p lay
The driver information display is located in the center of the instru­
ment cluster => fig . 7 .
The driver information system updates important information in the center display in clear view of the driver. In an easy to understand
format, the display tells you how your vehicle is functioning
at t he
cu rre nt m omen t.
For example, the display can tell you how many
miles (kilometers) you can still drive until it is time to bring your
vehicle to your authorized Audi dealer for a scheduled Maintenance Service . This feature helps preventing costly repairs. It is just one of
many different items of information availab le for recall. The display
a lso gives you a "status report" whenever the
so und s ystem , tel e­
ph on e, a nd navi gation
systems are being used.
Detailed instructions for operating the Audi Navigation System* are provided in separate manuals . The Driver Information System provides the following functions:
Sound system display
Outside air temperature
Door open indicator
Service interval display
Auto Check system
Speed limiter
Selector lever (S t ronic)

Service interval display
The service interval display reminds you when your next
service is due.
Fig. 13 Section of
instrument cluster:
Service interval display
The service interval display detects when which service category is
required for your vehicle. It works in two stages:
• Service Reminder : Starting with a certain mileage before a
service event, this message appears when the ignition is switched
on:
SERVICE IN 5500 Ml 150 DAYS.
• Service Event:
If the due date for servicing has passed, the
message
SERVICE EXCEEDED! appears This message is accompa ­
nied by a warning signal. And the type of service needed is
displayed.
Checking the Remaining Distance
By briefly pulling the knob,=> fig. 13 -Arrow -, the remaining
distance and time to the next service schedule is displayed with the
ignition on . The distance remaining is updated every 300 miles (500
Controls and equip ­
ment
Driver information system
km). The next scheduled oil change and thereafter the next sched­
uled service will be displayed.
For new vehicles or after the vehicle has been serviced, the next
scheduled service will only be displayed after 300 miles (500 km)
have elapsed. Until this distance has been travelled, the display will
show
OIL CHANGE IN----- Ml ---DAYS and SERVICE IN----- Ml --­
DAYS.
To reset the display
The dealership performing the service resets the display when the service has been completed . You can reset the display in the instru ­
ment panel only if an oil change has been done. Proceed as follows:
• Switch the ignition on .
• Pull on button=> fig.
13 -Arrow-, and the following message
appears:
SERVICE EXCEEDED !.
• Keep pulling on the knob until OIL CHANGE IN ---- -Ml ---DAYS
appears in the display. If the reset button is not pulled within 5
seconds, the display reset mode closes.
[ i] Tips
• Do not reset the display between service intervals. Doing so will
result in an incorrect display.
• If service was not performed at the correct time or the service
interval display was not reset after service was performed, the addi ­
tional mileage driven or the elapsed days will be shown as negative
numbers.
• If the battery is disconnected, the Service Interval Display values
are retained.
• If a priority 1 malfunction is present (red symbol), the distance
remaining cannot be called up. •

Driver information system
[ i] Tips
• The engine oil pressure symbol 9:::r. is not an indicator for a low
engine 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.
• The yellow oil level warning indication · requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning symbol
9:::r. starts to flash before you respond to the
low oil level warning . By then, your engine may already have
suffered serious damage. •

Yellow symbols indicate a priority 2 malfunction -Warning!
When a yellow symbol appears, a warning tone will sound
once .
Check the displayed function as soon as possible . If more than one
priority 2 malfunction is detected, all symbols will appear one after
the other for about two seconds.
To display driver information
As an example, the[} symbol appears in the display . If you now
press the button =>

one half. Never drive faster than the posted speed limit and weather
conditi ons permit. •
Reducing unnecessary Idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the eng ine run at
idle.
I t makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at railroad crossings, or at traffic lights that have long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle . However, wear and noxious emissions a re especial ly
high when the engine is warming up . So you should drive away as
soon as you start the engine and avoid running at high RPMs whi le
the engine is stil l warming up .
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idl ing also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .•
Regular maintenance
A badly tuned en gine unnecessarily wastes a lot of fuel.
- Have your v ehicl e serv ice d at reg ular intervals.
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
By having your vehicle regularly serviced by an Audi dea ler helps to
ensure that i t runs properly and economically . The conditio n of your
vehic le not only affects its safety and abi lity to hold its va lue, it also
affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load and speed .
I t is normal for the oi l consumption of a new eng ine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometres) be fore you can proper ly assess o il consumpt ion.
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
t he service recommendations in your Main tenance
& Warranty
booklet. Lack of proper ma intenance as well as improper use of the
vehicle wi ll impair the function of the emission control system and
cou ld lead to da mage.
• Do not alter or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do no t al te r or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
veh ic le' s Emission Control System and o ther i mportant vehicle
components. •
Fewer short trips
Fu el consu mption will alwa ys be relatively high on shor t
trips.
- Try to avo id driving short dista nce s wi th a cold engine.

At the time of printing, engine oils available in the U.S . and Canada
t hat 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 follow ing spec ifica tions pr inted on the oil container:
Au di oi l stan dar d VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and o il quality standards.
V isc osit y
Engine oils are graded according to their viscosity . The proper
viscosity grade oi l for your engine depends on climactic or seasona l
conditions where you drive . You can use oil with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi ­
tions.
However, if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we s trong ly recommend
that you a lways 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 o il while on the road.
On ly if the level of the oil is at or below the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standa rd
VW 502 00 specifications is available -may you top off with a high
qual ity engine oi l, preferably synthetic -based, t hat meets ACEA A3,
ACEA A5 or ACEA 85, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, dur ing the entire time between oi l change intervals, never
top off w ith more than a total of 0.5 qt/liter engine oil that does not
confo rm to Audi oil specificat ion VW 502 00. For more information about engine oil that has been approved for
your vehicle, p lease con tac t ei the r your authorized Audi dea ler or
Aud i Customer Relations at 1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .audicanada.ca. Here you will a lso find a
current list of oils (manufacturers, brand names etc.l that conform
to Audi oi l standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the
mi leage (k ilometers) and time intervals specified in your vehic le's
Maintenance
& Warranty booklet. Do not exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expens ive eng ine repairs.
Changing the oil at the recommended interva ls is so very important
because the lub ricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your oil
changed, ask you r authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oi l mo re often if you drive mostly short
distances, operate the vehicle in dusty areas o r mostly under stop­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long per iods.
Detergent additives in the oil will make fresh oi l look dark after the
engine has been running for a sho rt time. Th is is normal and is not
a reason to change the oil more often than recommended.
D amag e or malfun ctions due to la ck of mai nten ance
It is essential that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance
& Warranty booklet . Your dealer wi ll 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. •

Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service s tation.
Before you check anything in the engine compartment, alway s read
and heed all WARNINGS=>
& in "Working in the engine compart ­
ment" on
page 220.
The engine oil must be changed according to the intervals specified in your Maintenance
& Warranty book let. This is very important because the lubricating properties of oil diminish gradually during
n
ormal vehicle use .
Under some circumstances the engine oil should be changed more
frequently. Change oil more often if you drive most ly short
distances, operate the vehicle in dusty areas or unde r predomi­
nant ly stop -and -go traffic conditions, or have your vehic le where
t emperatures remain below freezing for extended per iods .
Detergent additives in the oi l wi ll 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 oi l more often than recommended.
Because of the problem of proper disposal, along with the special
t ools and necessary expertise required, we strong ly recommend
that you have your oil changed by an authorized
Aud i de aler or a
qualified serv ice stat ion.
If you choo se to change your oil your self , please note the fo llowing
i m portan t information:
& WARNING
To reduce the ri sk of personal injury if you m ust change th e engine
oil in y our v eh ic le you rself:
• Wear eye protection.
• To reduce the risk of burns from hot engine oil , let the engine
cool down to the touch.
• Wh en removing the oil dra in plug with your fingers , st ay as far
away as possible . Al way s keep your fore arm p ara llel to the ground
to help pre vent hot oil from running down your arm.
• Drain the oil into a contain er de signed for thi s purpo se , o ne
large enough to hold at lea st the total amount of oil in your engine .
• Engine oil is pois onou s. Keep it well o ut of the reach of children .
• Con tinuou s contact with used engine oil i s harmful to your

Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style.

The original tires on your veh icle have 1/16 inch (1.6 mm) high "wear
indicators" => fig . 162 running across the tread. Depending on the make, there will be six to eight of them evenly p
laced around the
t ire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be rep laced. Different figures may apply in other countries =>& .
Tire p ressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out . Forth is reason, tire pressure must be checked
at least once a month
==> page 244.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer 's suggested tire rotation intervals. Please
remember the following:
• Tire rotation interva ls may differ from the vehicle service inter­
vals outlined in your Maintenance and Warranty Booklet .
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals.
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to a ll-wheel drive (quattro®l .
• Please rotate tires as shown ;;:;:, fig. 163.
• Extra care must be taken when rotating direction -specific tires
==> page 272.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usual ly feel through the
steering wheel. ...

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, etc., some service work
should be performed between the intervals specified . This applies
particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
