Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip computer display: Average fuel mileag e
The fo llowing information is continuously
eva luated by the trip computer and can be dis
p layed sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your vehicle wi ll be able to travel on the cur
rent tank of fue l and with the same driving
style. The display changes in increments of 6
miles (10 km).
The cruising range is calcu lated based on the
fuel cons umption for the last 18 mi les
(30 km) . If you drive conservatively, the cruis
ing range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this disp lay to adjust
your driving technique to achieve a desired
mileage .
Current fuel mileage
The instantaneous fuel consumption in miles
per gallon (l/100 km) is shown in this display .
You can use this display to adj ust yo ur driving
technique to ach ieve a desired mileage.
Driver information display 25
Fuel consumption is recalcu lated at intervals
of 33 yards (30 meters). This display switches
to gallons/hour (liters/hour) when the veh icle
is not moving.
Average speed
The average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that yo u have been driving
s ince you last reset the memory appears in
th is disp lay.
Distance
The distance that has been covered since the
last time the memory was cleared appears in
the d isplay .
(0 Tips
- Fuel consumptions (average and cur
rent), range and speed are displayed in
metric units on Canadian mode ls.
- All stored values will be lost if the vehi
cle battery is disconnected.
Memories
The trip computer is equipped with two fully
automatic memories as well as an efficiency

The efficiency program can help you to use
less fuel.
It evaluates driving information in
reference to fue l consumption and shows oth
er equipment influencing consumption as well
as shift recommendations. Fuel economy
messages

Fuel economy messages
App lies to vehicles: with trip computer w it h eff ic iency
p rogram
Fig . 16 Display: fuel economy message
Fue l economy messages are disp layed when
fuel consumption is increased by certain con
ditions. If you follow these fuel economy mes
sages, you can reduce your vehicle's consump
tion of fuel. The messages appear automati
cally and are only displayed in the effic iency
program. The fuel economy messages turn off
automatically after a certain period of time.

@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels.
Fuel economy, environmental impact, and
wear on you r engine, bra kes and t ires largely
depend on th ree factors:
= your persona l dr iving style
- operating conditions
- technica l lim itations
I f you anticipate what yo u need to do next and
drive economically, you can easi ly cut your
fuel consumption by 10-15 percent. This sec
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
@ Tips
The consumpt ion estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption on the
road, wh ich will vary depending upon vehi
cle load and speed, road and weather con
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
" Avoid unnecessary accele rat ing and braking.
Dri vin g and en vironm ent 195
Vehicles use the most fue l when they a re ac
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
" Try and keep well below your car's maxi-
mum speed.
Acce lerating gently red uces fue l cons ump
tion, engine wear, and does not disturb the environment.
Fuel consumpt ion, exhaust emiss ions and en
gine noise increase disproportionately at high
speeds . If you drive at approximately th ree
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv
ing the vehicle.
" Do not warm up the ve hicle by letting the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail
road crossings, or at traffic lig hts t hat have
long waits on red . T ur ning the eng ine off for
just 30-40 seconds saves mo re fuel than is
bur ned star ting the e ngine again.
It takes a long t ime for the engine to warm up
fully when it is run ning at idle . However, wea r
and noxious emissions are espec ia lly high
whe n the eng ine is wa rm ing up. So yo u shou ld
drive away as soon a s you start the e ngine and
avo id r unning at high rpms whi le the engine is
still warming up.

196 Driving and en vironm ent
(0 Note
Do not leave engine idling unattended af
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in
over
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
.,. Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
con sump tion .
C heck your oil each time you fill your tank.
The amount of oil used is related to engine
l oad and speed.
I t is normal for the oil consumption o f a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You mus t drive yo ur vehicle abo ut 3,000 miles
(5,000 kilometers) be fo re yo u can properly
assess oi l consumption.
This a lso applies to fuel consumption and en
g ine output.
(]) Note
-Have yo ur vehicle maintai ned properly
and in accordance with the service re c
ommendations in your War ran ty
& Mai n
tenance bookle t. Lack of proper mainte
nance as well as imp roper use of the
ve
hicle will impair the function of the
emission control system and could lead
to damage. -
Do not alter or
remove any component of
the Emission Control System unless ap
proved by the manufacturer .
- Do not alter or
remove any device, such
as heat shie lds, switches, ignition w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
oper ating temperature to
reduce fuel consumpt ion and nox ious em is
s ions effectively.
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 m iles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km),
the engine is at its prope r operating tempera
tu re and fuel economy has reached a normal
level. So you can see that yo u should avo id
short trips whenever poss ible.
T he
outside temperatur e is also cr it ical in t his
regard. Your car consumes more fue l in the
winter tha n in the s umme r.
212 Fuel supply and filling your fuel tank
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving .
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea
sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flex ible fuel en
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t these
requirements may cause corrosion and
damage to plastic and rubber compo
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identif ied.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties .
- If you experience a loss of fuel economy
or driveab ility and performance prob
le ms due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: wit h flexible fue l e ngi ne
Vehicles with f lexible fuel engines may be op
erated with bio-ethanol fuels such as E85 (85% ethano
l and 15% gasoline) or with un
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption wi ll increase when us
ing bio-ethano l fue ls due to the lower amount
of energy contained per unit volume in etha
nol.
Warming up the Flexible fuel engine in
low temperatures
Due to the chemical composition of bio-etha
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . Th is fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru
ment cluster disp lay, drive with a warm en
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha
nol in the fuel can cause damage to the
eng ine or to the fuel system .
- Read and follow the information and t ips
about gasoline¢
page 211.
Gasoline additives
A major concern among many auto manufac
turers is carbon depos it build-up caused by
the type of gaso line you use .
Although gasoline grades differ from one manufacturer to another, they have certain
th ings in common . All gasol ine grades conta in
substances that can cause deposits to collect
on vital engine parts, such as fue l injectors
and intake valves. A lthough most gasoline
brands include add itives to keep engine and
f uel systems clean, they are not equally effec
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For mo re information on TOP TIER .,.
220 Check ing and filling
temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, a ll in
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con
sumption 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 condit ions . Further fac
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 221. Top off the oil at your earliest
convenience ¢

A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢

-If you have t he impression yo ur engine
consumes excessive amoun ts of o il, we
recommend that you consu lt an author
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in m ind that the accurate measu rement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.
-
(D Note
Driving without valve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely
mounted on the valve .
@) For the sake of the environment
Underinflated tires will also increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important pa rts of the
ve hicle and can lead to sudden tire failure, in
cluding a blowout and sudd en d eflation that
c a n cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exce eded . Vehicl e load includes ev erybody
and everyth ing in and on the vehicle. These
load limi ts are techn ically referred to as the
vehicle's
Gross Vehicl e W eight Rat ing
("GVWR ").
The "GVWR" includes the we ight of the basic
vehicle, all fac tory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load . The maximum load includes
the number of passengers that the vehicle is
i ntended to ca rry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger a t a des igna ted seat ing pos ition
and the tota l weight of any l uggage in the ve
h icle. If you tow a trailer, the weig ht of the
trailer hitch and the tongue we ight of the
loaded traile r must be included as part of the
vehicle load .
The
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
Tire s an d wheel s 239
The Gross Vehicle Weight Rat ing and the
Gross Axle Weight Rating are listed on th e
safety comp liance sticker label located on the
driver's side B-pillar. Audi has 4 seat ing pos i
tions, 2 in the front and 2 in the rear for total
seat ing capac ity of 4. Each seating position
has a seat belt ¢
page 134, Safety belts .
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue we ight of the
loaded tra ile r) is lim ited. The more passen
gers in the vehicle or passe ngers w ho are
heavier than the standard we ights assumed
mean that less weight can be carried as lug
gage.
T he tire pressure label on your Aud i also lis ts
t h e maximum combined weight of a ll of the
occupants and l uggage or other cargo that
the ve hicle can carry. For the location of the
l abel ¢
page 235, fig. 176.
A WARNING
Overloading a vehicle can cause loss of ve
h icle contro l, a crash or other accident , se
rious personal injury, and even death .
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
ve hicle from handling properly and in
crease the risk of the loss of vehicle con
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
ve hicl e with in a safe distance .
- Tires o n a vehicle that has been overload
ed can fail suddenly, incl uding a blowout
a nd sudden defla tion, causing loss of
control and a crash .
- Always ma ke sure t hat the to tal load be
i n g transpo rted - incl udi ng t he weight of
a trailer hitch and the tongue we igh t of a
loaded trailer -does not make the vehi
cle heavier than the vehicle's Gross Vehi
cle Weight Rating.
