Trip computer
Introduction
The trip computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time.

m ileage
The following driving information is continuously evaluated by the
trip computer and can be disp layed sequential ly in the instrument
cluster display .
Fuel ran ge
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to trave l on the
current tank of fuel and with the same driving sty le. The display
changes in increments of 6 miles (10 km).
The cru ising range is ca lculated based on the fuel consumption for
the last 18 miles (30 kml. If you drive conservatively, the cruising range will increase.
A ve ra g e fu el m ilea ge
The average fuel economy in MPG (1/100 km) since you las t cleared
the memory appears in this display. You can use this disp lay to
adjust your driving technique to achieve a desired mileage.
C urr ent fu el mi leage
The instantaneous fuel consumption in m iles per gallon {1/100 km)
is shown in this display. You can use this disp lay to adjust your
driving technique to achieve a desired mileage .
Fuel consumption is recalculated at intervals of 33 yards (30
meters). When the vehicle is stationary, the most recent fuel
consumption is displayed.
A ver age s peed
The average speed in mph (km/h) s ince the last time the display was
reset appears in the display .
Elapse d tim e
The length of time that you have been driving since you last reset
the memory appears in this display.
[ i ] T ip s
• Fuel consumptions (average and current), range and speed are
displayed in metric units on Canadian models.
• All stored values will be lost if the vehicle battery is
disconnected. •

- To adjust the direction o f the airflow from the o utlet,
move the tab in the cen ter of the o utlet in the desired
direction . The direction of the air delivered from the
vents can be adjusted hor izontally and vertically .
The air outlets are actuated either automatically or manually
depending on the operating mode selected . Heated or unheated
fresh air, or cooled air flows from the vents .
The air outlets to heat the rear footwell are located under the front seats.
[ i ) Tip s
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
out lets completely .•
Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditioner only when necessary . A lso please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
- If yo u are g oing to dr ive wit h the w indows or Panorami c
sliding sunroof* open, use ECON .
- If the ve hicle is e xtremely ho t due to the heat of t he s un,
br iefly open doors and windows .
Contro ls and eq uip­
ment

Aut omatic l ower ing :
When a speed of about 75 mph (120 km/h)
is exceeded for more than 30 seconds, the vehicle is automatica lly
lowered by about 0 .6 inch (15 mm) to the
low level, which is more
suitable for highway speeds . Road holding is opt im ized as a result
of the lower center of gravity and fuel consumption is reduced as a
result of reduced wind resistance. When a speed of about 100 mph
(160 km/h) is exceeded for more than 20 seconds, the vehicle is
automatically lowered by an additional 0 .8 inch (20 mm) to
highway
level.
• Automatic rai sing: When the vehicle is at highway level and the
speed fa lls be low about 80 mph (130 km/h) for more than 20
seconds, the vehic le is automatica lly raised to
low level. The vehicle
is automatically raised again to
normal level if the speed fa lls be low
about 44 mph (70 km/h) for a period of 2 minutes. The vehicle is
ra ised immediate ly when speed fa lls below about 22 mph (35 km/h).
dynamic
Select the dynamic mode if you prefer a sporty suspension sett ing.
I n this mode, the vehic le is lowered to
/ow level while it is sti ll
stationary and sporty damping characteristics are selected . The
warning light~ in the instrument cluster will come on for a few
seconds jus t to remi nd you of the reduced ground clearance .
I f you switch off the engine while the vehicle is in the dynamic mode
and then switch on the ignition once again, the~ warning light
wi ll also come on again for a few seconds as a reminder.
• Automatic lowering : When a speed of about 100 mph (160 km/h)
is exceeded for more than 20 seconds, the ve hicle is auto matica lly
lowered by 0.8 inch (20 mm) to
highway level.
• Automatic rai sing: The vehic le is automatically raised to low level
again, if the speed falls below about 80 mph (130 km/h) for a period
o f 20 secon ds. The ve hicle is ra ised i mmediately whe n speed falls
below about 22 mph (35 km/h). .,_

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) * and fully loaded vehicles .

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary =citing
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 engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emissions are especially
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 while
the engine is still 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 idling also produces heat, which could result in overheating or other damage to the vehicle or other
property .•
Regu1ar ma1--.tenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehic le serviced at regular intervals . By having your vehicle regularly serviced by an authori
zed Audi
dea ler helps to ensure that it runs properly and economica lly. The
condition of your vehicle not only affects its safety and ability to
hold its value, it a lso affects
fu el con sumpti on.
C he ck your oil each time you fill your t ank .
The amount of oil used is related to engine load and speed.
It is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
T his also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emiss ion Control
System unless approved by the manufacturer.
• Do not alter or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehicle 's Em ission Control System and other important vehicle
components .•
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short dista nces wi th a cold engine. _,

The engine and catalytic converter have to reach their optimal oper­
ating temperature to reduce fuel consumption and noxious emis ­
sions effectively.
Just after starting, a cold engine in a mid -size car only achieves a
fuel economy of 6-8 miles per gallon (30-40 1/100km) . After about a
half a mile, fuel economy climbs to 12 mpg (201/100 kml. After about
2.5 miles (4 km), the engine is at its proper operating temperature
and fuel economy has reached a normal level. So you can see that
you should avo id short tr ips whenever possible.
The outside temperature is also critical in this regard. Your car
consumes more fuel in the winter than in the summer. •

---------------------=----"=---------
0 Note
Driving 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 your concern properly diagnosed. Keep in mind
that the accurate measurement of oil consumption 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. 284 or
=> fig. 285. Top off the engine oil, if applicable

- You must add oil. Afterwards, the oil level should be
within range @.
The oil level needs to be checked at regular intervals. The best times
to do this are whenever you refuel and prior to long tr ips.
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 (1 liter
per 2.000 km). Consumption may be higher within the first
3.000 miles (5.000 km) .•
