Driver inf ormation sy ste m
To ta l-tr ip mem ory ( Trip compu te r 2)
Unlike the single -trip memory, the total -tr ip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manua l resets.
Fu el r an ge
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to travel on the
current tank of fuel and with the same driving sty le . The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
t he last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Average fuel m ile ag e
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C ur rent fuel mil eage
The instantaneous fuel consumption in mi les per gallon (1/100 km)
is shown in th is d isplay. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fue l consumption is recalcu la ted at intervals of 33 yards (30
meters). When the vehicle is stationary, the most recent fuel
consumption is d isplayed .
Average speed
The average speed in mph (km/h) s ince the last time the display was
reset appears in the display .
Elap se d time
The length of time that you have been driving since you last reset
the memory appears in this display.
Di stance
The elapsed distance since the last time the memory was cleared
appears in the display. The maximum distance that can be recorded
is 9,999 .9 miles (9,999 .9 kilometers).
[ i ] Tips
• 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 .•
Operation
The trip computer is controlled by two switches on the
windshield wiper lever.

- Lack of proper maintenance as well as improper use of the
vehicle will impair the function of the emission con trol system
and could lead to damage.
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 su lfur content of the fuel
being used. Using a different brand of fuel may he lp, 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 spoilers 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 t ires largely depend on three factors:
• your personal driving style
• operating condit ions
• technical limitations If
you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumption by 10-15 percent . This
section will give you some tips on how you can he lp the environ­
ment and your pocketbook .
[ i ] Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which will vary
depend ing upon vehicle 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 are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example 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 maximum speed.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by

Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same model::::;,
page 296.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi
dea ler o r qu alif ied wo rksh op.•
Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performan ce of low -aspect -ratio t ires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and alway s before a
long trip::::;,
page 244, "Checking tire p ressure".
What you can do to a void tire and rim damage
L ow a spect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_
