If you anticipate w hat you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. Th is sect ion will
g ive you some tips on how you can help the envi­
ronment and your pocketbook.
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depend ing upon vehicle load and
speed, road and weather conditions, trip
length, e tc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­ b le -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
.. Try and keep well be low your car's max imum
speed .
Accelerating gently reduces fuel consumpt ion,
engine wear, and does not d isturb the env iron­
ment .
Fue l consumption, exha ust emissions and eng ine
noise increase disproportionately at high speeds.
If you drive at approx imately t hree quarters of
top speed, fuel consumpt ion w ill be reduced by
one half . Never dr ive faste r than the posted
speed limit a nd weather conditions perm it.
Dri ving
Reducing unnecessary idling
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 lett ing the en-
gine run at idle.
It is efficient to switch off the engine when stop­
ped at ra ilroad crossings and long red lights.
Turning the engine off for just 30-40 seconds
saves more fuel than is b urned by starti ng the
engine aga in .
It takes a long t ime for the engine to warm up
fully when it is ru nning at idle. However, wear
and noxious emissions are espec ia lly hig h when
t h e engine is warming up. So you should d rive
away as soon as you sta rt the eng ine and avoid
run ning at high rpms w hile the eng ine is s till
warmi ng up .
@ Note
Do no t leave eng ine idl ing una ttended afte r
s ta rtin g.
If war ning lig hts s hou ld come on to
i ndica te imprope r operat ion, they would go
u nheede d. Extended idling also produces
heat, which could result in overheat ing or oth­
er damage to the ve hicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your ve hicle serviced at reg ular in tervals.
B y havi ng your ve hicle regu la rly se rv iced by an
Audi dealer he lps to ensu re that it ru ns p rope rly
and economically. The condi tion of your veh icle
not only affects its sa fety and ability to ho ld i ts
val ue, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certai n m ile-
age has been dr iven. ...,
71

Driving
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumption.
This also applies to fuel consumption and engine
output.
@ Note
- Have your vehicle maintained properly and
in accordance w ith 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 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 Emission Control System and other important vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
.,. Try to avoid driving short distances with a cold
engine.
The eng ine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively .
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 en­
gine is at its proper operating temperature and
fuel economy has reached a normal level. So you
can see that you should avoid short trips whenev­
er possible.
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back .
Fig. 67 Ste ering co lumn : steer ing colu mn adjus tmen t l eve r
.,. Tilt the lever ¢ fig. 67 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 ¢
page 131, fig. 113. If you do not
maintain this distance, the airbag system
will not be able to provide its full protection
¢page 131, fig. 113.
-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 Fill in g
These fuels contain substances that can se ­
verely damage the fuel system and the en­
gine if the engine is started .
- If the diesel f uel quality is poor, it may be
necessary to have the water d rained from
the water separator in the
fuel filter more
often than specified in the maintenance
schedule. This can help reduce engine ma l­
funct ions
c:> page 2 3.
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side pane l behind the fuel f iller flap.
If the power locking sys tem should fail, you can
still open the flap manua lly -for detai led instruc ­
tions see
c:> page 194.
You can find the fue l tank capacity of you r vehicle
in
c:> page 260.
The label on the inside of the fue l filler flap te lls
you t he cor rect fuel for your vehicle. For more in­
form ation abo ut fue l specifications, see
c:> page 190 .
Your vehicle fuel tank has an on board refue lling
vapor re cove ry system . This feature helps to p re­
ve nt fuel vapors from escaping from the tank and
pollut ing t he environment w hile you refue l yo ur
ve hicle. In orde r to fill the tank p roperly whi le
protecting the environment, please follow this
refueling procedure carefully.
A WARNING
Under normal operating conditions, never ca r­
ry additional fuel containers in your car . Gas
canisters and ot her conta iners used to trans­
port fuel can be dangerous . Such contai ners,
full or empty, may leak and could cause a fire
in a collision. If yo u m ust t ransport fue l to
use fo r yo ur l awn m owe r, snow b lower, etc.,
be very ca re ful and a lways observe loca l and
state laws rega rding the use, transportation
and sto rage of such fuel containe rs . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 - 86).

(D Note
Never drive your vehicle until the fue l tank is
complete ly empty . The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic converter.

The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
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 fue l 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, fue l spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
f uel will a lready se riously degrade the
performance of the c ata lytic conver ter.
- Do not exceed the co rrect engine oil leve l
9page203.
-Do not d rive until the fuel tank becomes
complete ly empty. The eng ine could misfi re.
U nburned f uel co uld also ge t in to the e x­
haust system and this could ca use the cata ­
l ytic converter to overheat.
- Do no t sw itch off the ignition wh ile the vehi­
cle is moving.
- Do not con tinue to oper ate yo ur vehicle un­
der these cond itions, as o therwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.
- To assure efficient ope ration of the Emission
Control System:
Checking and Fillin g
- Have your vehicle maintained properly and
in accordance with the serv ice recommen­
dat ions in yo ur Warranty
& Maintenance
booklet.
- Lack of prope r maintenance as we ll as im­
p roper use of the vehicle will impair the
f u nction 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 exha ust gas can have a
su lfur-like exhaust gas sme ll under some op­
erating states. Th is depends on the s ulfur
content of the fuel b eing used. Us ing a diffe r­
ent bra nd of fue l may he lp, or fi lling the tank
wi th lead-free su per grade gaso line.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
T he diese l part icu late filter filters nearly all of
the soot pa rticles ou t of the exha ust. The filter
cl ea ns itself a utoma tic all y unde r no rm al driving
con dit ions. If the filte r cannot clean itse lf (for ex­
amp le, because yo u are only driving sho rt distan ­
ces), th e fi lter becomes clogged with soot and
the
II symbol for the diese l partic ulate filter il­
l uminates
9page 22.
A WARNING
-Do not park your veh icle over flammable
materials such as grass or leaves because
the high temperature of the diesel part icu­
la te filte r could sta rt a fi re.
-
- Do not app ly an underbody protectant in the
exhaust system area or a fire cou ld start.
Selective catalytic
reduction
General information
App lies to vehicles: wit h diese l eng ine
In veh icles with selective catalytic reduction, a
u rea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
conve rter to redu ce nitrogen emissions.
