~/o Malfunction Indicator Lamp
(MIL)
The Malfunction Indicator Lamp (M IL) Ill
(USA models);II (Canada models) in the in­
strument cluster is part of the On-Board Diag­ nostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized.
This indicates that the MIL is work ing proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may ex ist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your author ized Audi dealer.
If the lig ht ill uminates, the e lectronic speed
limiter may also be malfunctioning. For more
information c:::> page 25, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:::> page 192.
Electronic speed limiter
Your veh icle may be factory equ ipped with
tires that are rated for a maximum speed of
130 mph (210 km/h) . Thi s is less than the
maxim um speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle also has an electronic speed limit­
er . The electronic speed limiter prevents your
veh icle from going faster than the tire speed
rating. For more informat ion
c:::> page 224,
Speed rating (letter code).
If the engine control unit receives fau lty vehi ­
cle roadspeed signals, the Malfunction Indica­
tor Light (MIL)
¢..ijj will illuminate. If this oc-
Driver information display 25
curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING -
A lways observe the posted speed lim its
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.

172 Driving and en vironm ent
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 most fuel when they are ac­
celerati ng. If you anticipate what is go ing to
happen next, you will need to brake less and,
thus , accelerate less . let the vehicle coast
whenever poss ible -fo r example whe n you see
th at the next traffic ligh t is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
,. Try and keep well be low your car's max i-
mum speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
env ironment.
Fuel consumption, ex ha ust em issions and en­
g ine no ise increase d isproportiona tely at hig h
speeds . If you dr ive at approximately three
qua rters of top speed, fuel consumption will
be reduced by one ha lf . Never dr ive faster
tha n the posted speed limit a nd weather con­
d it ions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel.
,. Shut the engine off when you a re not dr iv­
ing the vehicle.
,. Do not warm up the veh icle by letting the
engi ne run at idle.
It makes sense to shut off the eng ine in traff ic
jams, when waiting for trai ns to pass at ra il­
road cros sings, or at t raffic ligh ts that have
l ong wa its on red. Turning the engine o ff fo r
just 30 -40 seconds saves more fue l than is
bu rne d starting the engine again.
It takes a long t ime for the engine to warm up
fully when it is running at id le . However, wea r
and noxious emissions are espec ia lly high
when the eng ine is wa rm ing up. So you shou ld
drive away as soon as yo u start the engine and
avo id running at high RPMs w hile the eng ine
i s s till warm ing up .
(D Note
Do not leave engine idling unattended af­
ter start ing . If warni ng lig hts sho uld come
o n t o indicate improper ope ration, they
would go unheeded . Extended idli ng also
produ ces heat , w hich could result in ove r­
hea ting or other dam age to the veh icle or
other property .
Regular maintenance
A badly tuned engine unne cessarily wastes a
lo t of fuel.
,. Have your ve hicle serviced at reg ular inter-
vals.
By havi ng your ve hicle regu larly serv iced by an
a utho rized Aud i deale r helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your ve hicle not only affe cts i ts safety and
abili ty to ho ld i ts va lue , it al so a ffects
fuel
con sumption .
Check your oil each time you fill your tank .
The amount of oi l used is re lated to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven .
You must drive your vehicle about 3,000 mi les
(S,000 kilometers) before you can properly
assess oil consumpt ion.
T his also app lies to fue l cons umption and en­
gine o utp ut.
Q) Note
- Have your veh icle ma inta ined proper ly
and i n acco rdance with the service rec­
ommendations in your Warranty
&

Maintenance booklet. 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 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 burns the fuel at a poor rate of 6-8
miles per gallon (30-40 L/100km). Half a
mile down the road, the mileage improves
to 12 MPG (20 l/100 km).
It will take the
engine no less than
two and a half miles
(4 km) of driving to warm up to its proper
operating temperature and operate at an
economic mileage. This explains why taking
the car for short trips is a rather wasteful
convenience.
- The outside temperature is also critical in
this regard . Your car consumes more fuel in
the winter than in the summer.

cations . Th is eng ine needs the right kind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smoot hly and reliab ly. Choosing the right o il
and changi ng oil within the t ime and mileage
intervals printed in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to ­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine w ill
get the lubr ication it needs for proper opera­
tion.
