ment appears in the display . Other equipment that is currently affecting
fuel consumption is listed in the efficiency
program. The display shows up to three other
items of equ ipment @. The equ ipment using
the most fuel is listed first . If more than three
items using fuel are switched on, the equip ­
ment that is currently using the most fuel is
displayed .
A scale @also shows the current total con­
sumption of all other equipment .
Fuel economy messages
Fig. 9 Display : example o f a fuel econo my m essa ge
Fuel economy messages are displayed when
fuel consumption is increased by certain con­
ditions. If you follow these fuel economy mes­
sages, you can reduce your veh icle's consump­
tion of fuel. The messages appear automat i­
cally and are only displayed in the efficiency
program. The fuel economy messages turn off
automat ically after a certain per iod of t ime .
.,. To turn an economy message off immed i-
ately after it appears, press any button on
the mult ifunction steering wheel.
@ Tips
- Once you have turned a fuel economy
message off, it will only appear again af­
ter you turn the ign ition on again .
- The fuel economy messages are not dis­
played in every instance, but rather in in­
tervals over a period of time.

206 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving thro ugh water, for example on
flooded roads:
- The wate r must not be any higher than the
bottom of t he vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 80 .
(1) Tips
-Check the depth of the water before dr iv­
i ng th rough it.
- Do not stop the ve hicle, dr ive in reverse
or switch the engine off whe n driving
t hr ough water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r you r vehi­
cl e to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
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, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRON MEN TAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
11-Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system . It is effi­
cient to switch
off the engine in vehicles with­
out the Start-Stop-System when stopped at ra il road crossings and long red lights. Turning
the eng ine
off for just 30 -40 seconds saves
mo re fuel than is burned by s tarting the en­
gine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. Howeve r, 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 h igh rpms while the engine is
still warming up.
CD Note
Do not leave engine idling unattended af­
ter starting. If warning lights shou ld come
on to indicate improper operation, they
Dri vin g and en vironm ent 207
would go unheeded. Extended idling a lso
produces heat, which could result in over­
heating or other damage to the veh icle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
11-Have your vehicle serviced at reg ular inter-
vals .
By having your ve hicle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop­
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel co nsump ­
tion .
Chec k your oil e ach t ime you fill y our t ank.
T he amou nt of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also applies to fuel consumption and en­ gine output .
CD Note
-Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance book let . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impai r the function of the
em ission cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
t he Emission Control System unless ap­
proved by the manufacture r.
- Do not alter or remove any devi ce, such
as heat shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System

208 Driving and environment
and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
,.. Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating 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 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 proper operating tempera­
ture and fuel economy has reached a normal level. So you can see that you should avoid
short trips whenever possible.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer.

234 Checking and filling
temperatures stay below freezing point for long periods.
Detergent additives in the oil 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.
Damage or malfun ctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals 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 booklet . 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 timely 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, all in­
ternal combustion eng ines 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 specif ied break-in period (see
¢ page 204) 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 oxida­
tion level of the oil. 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 all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent checking of the o il lev ­
el, see Note.
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II lights up, you
sho uld check the oil leve l as soon as possible
c:> page 235. Top off the oil at your earliest
convenience
c:> page 235.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS
c:> A in Working in the engine
compartment on page 230.
(D Note
Driving with an insufficient o il level is like­
ly to cause severe damage to the engine.
(D 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, pref­
erably each time you refuel, and always
before going on a long trip.
- If you have th e 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 meas urement of oil con­
sumption requ ires great care and may
take some t ime. Your Audi dealer has in­
structions about how to measure oil con­
sumption accurately.
-

-Always make sure the transm ission se­
lector lever (automatic transmiss io n) is
in P (Park position) and the park bra ke is
applied.
@) For the sake of the environment
- Changing t he eng ine settings w ill ad­
versely affect em ission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
tions when d isposing of old engine oil,
used brake fluid, dirty engine coolant,
spent batter ies or worn out t ires.
- Undeployed airbag modules and preten­
s ioners might be classified as Perchlo­
