You must drive your vehicle about 3,000 miles
(5 ,000 kilomet ers) before you can prop erly as­
sess oil consumption .
This also applies to fuel consumption and engine output.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle 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 shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
• Try to avoid driving short dist ances with a cold
engine .
T he eng ine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consump tion and noxious emissions effec­
tively .
Just after starting, a cold engine in a mid-si ze car
only achieves a fuel economy of 6-8 mi/gal (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 prop­
er operating temperature and fuel economy has reached a normal level. So you can see that you
should avoid sho rt trips whenever possible.
The
outside temperature is also critical in this re­
gard . Your car consumes more fuel in the winter
than in the summer .
Driving
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fig. 74 St ee ring co lumn: steering col umn adjus tmen t leve r
• Tilt the lever¢ fig. 74 downward ¢&_ .
• Bring the steering wheel into the desired posi­
tion.
• Push the lever against the steering column un­
til it latches.
A WARNING
-
Incorrect use of the steering wheel adjust­ ment and an incorrect seating position can
cause serious injuries .
- Only adjust the steering column when the
vehicle is stationary so that you do not lose control of the vehicle.
-
- Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches (25 cm) dis­
tance between your chest and the steering
wheel
r:!> page 125, fig. 120. If you do not
maintain this distance, the airbag system
will not be able to provide its full protection
r:!> page 125, fig. 120.
-If your physical characteristics prevent you
from sitting at least 10 inches (25 cm) or
more away from the steering wheel, see if
your authorized Audi dealer or authorized
Audi Service Facility can provide adapters
that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision . Always make sure
that the steering wheel is level with your
chest.

Checking and Filling
"'Never put too much motor oil in your engine
¢ page 193 , Checking the engin e oil lev el and
adding oil.
"'Never try to push- or tow-star t your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the v ehi­
cle. The catalytic converter burns many of the pollutants in the exhaust gas before they are re­
leased into the atmosphere .
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become hot . This could result in burns .
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush , fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 193.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can reach the catalytic converter. This could re-
188
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.

which can usually be used throughout the entire
yea r.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty & Maintenance booklet .
- Use only a high qual ity eng ine oil that ex-

· 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 effect ive lubricat ion and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 65) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con­
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase over
ti me unt il replacement of wo rn compo nents may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
chec k the o il level as soon as possible
¢
page 193. Top off the o il at your earlies t con­
venience

A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS

gine at regular inte rval s, preferably each
t ime you refuel , and alway s befo re going
on a long trip.
- If y ou have the impressio n your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consump tion
requi res great care and may take some
time. An a uthorized Audi dea ler has instruc ­
tions about how to measure oil consump ­
tion accurately .

Check ing and F illing
- After adding engine oil, the o il level must
not be above the marking@~
fig. 162, be­
cause this increases the risk of cata lytic con­
verter and/or eng ine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Fac ility to
have excess engine oil extracted if necessa­
r y .
- Do not mix any additional lubricants into
the engine o il. Damage cause by such addi­
tives is not cove red by the war ranty .
@ For the sake of the environment
-Engine o il should never enter the sewe r sys­
tem or come into contact with the ground
under any circumsta nces.
- Pay attention to legal requirements when
d ispos ing of empty oil containe rs .
(D Tips
The engine oil consumption may be up to 0.5
quart/600 m iles (0.5 liter/1,000 km), de­
pending on d rivi ng s tyle and operating condi­
tions. Consumption may be higher du ring the
fi rst 3,00 0 miles (5, 000 km). Be cause of this,
t he engine oil leve l m ust be chec ke d r egular ­
ly. It wo uld be best to check each time you re ­
fue l your vehicle and before long drives .
Changing the engine oil
We recommend that hove your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check a nyth ing in the eng ine compart­
men t,
alway s read and heed all WARNINGS
~ page 188.
The engine oil must be changed accord ing to the
i n tervals specified in your Warran ty
& Mai nte­
nance booklet . This is very importan t because the
lubricating p roperties of o il diminish gradually
during normal vehicle use.
Under some c irc ums tances the eng ine o il sho uld
be changed more frequently. Change oil more o f­
ten if yo u drive most ly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions, or have your vehi-
194
de where temperatures remain be low free zin g
for extended periods.
Dete rge nt additives in the oi l will make fres h oil
l ook dark a fter the engine has been r unning for a
short time . This is normal and is no t a reason to
change the oi l more often than recommende d.
Bec ause of t he pr oblem of prope r dispos al, along
with t he speci al tools and ne ce ssary expertise re­
quired, we strongly recommend that yo u have
your oi l changed by an authorized
Audi dealer or
