22 Instruments and warning /indicator lights
When this symbo l ml illuminates, it means
that Adaptive Light is defective. Go to a quali­
fied workshop to have the headlights or the
control unit for the Adaptive L ight repaired.
@, o Light/rain sensor defective
App lies to vehicles: with automat ic headlights
The indicator light indicates a defect in the
automatic headlights/automatic wiper sys ­
tem .
If the symbo l illuminates, the light sensor has
failed. For safety reasons , the low beams are
turned on permanently with the switch in
AU­
TO . However, you can continue to turn the
lights on and off using the light switch . In the
case of a defect in the rain sensor , the w ind­
sh ield wiper lever functions are st ill available .
H ave the light/ra in sensor checked as soon as
possible at an authorized Audi dealer.
; Audi magnetic ride
Appl ies to vehicles: with Audi magnetic ride
The indicator light monitors vehicle damping.
The indicator light E illuminates when the ig­
nition is switched on as a function check.
@ Tips
If the indicator lamp illuminates while you
are driving, there is a malfunct ion in the
veh icle damping. The chass is should be in­
spected immediately by an authorized Au­
di dealer.
~ Diesel particulate filter clogged
Applies to vehicles: with diesel engine and diesel particu­
late fi lter
1/1 Particulate filter ! See owner's manual
If the indicator light II in the instrument
cluster comes on, the diesel particulate filter has become blocked with soot as the result of
constant short-distance driving. When the
II symbol illuminates, you can alter your
driving style to assist the filter self-clean ing
p rocess. Drive for approximately 15 minutes
in 4th or 5th gear (automatic transmission with the se
lector lever in the S position) at a
minimum speed of 37 mph (60 km/h) and an
engine speed of approx imately 2,000 RPM .
The temperature increase that will result from
this can burn off the soot in the filter. The
symbol will switch off when the cleaning is
successful. After a successful cleaning, there
is no need to bring the car to an authorized
dealer or qualified workshop because this is
part of normal vehicle operation .
If the symbol
DI does not switch off, see
your autho rized dea ler or other qualified
workshop to have the problem corrected .
As long as the indicator light
11!1 remains on
(diesel part iculate filte r plugged), you ca n ex­
pect increased fuel consumption and possibly
also a loss of engine performance.
For more information on the diesel particu­
late filter, refer to~
page 171 .
A WARNING ,__
Always adapt your speed to the current
weather, road and traffic conditions. You
should never disobey traffic laws in order
to follow driving recommendations .
¢ ¢Turn signals
-
The indicator light blinks when you use either
turn signal.
Whenever you use the left B or the right fl
turn s ignal, the indicato r light blinks . When
you use the emergency f lasher, both indicator
lights flash.
If one of the turn signal light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal.

-Have your vehicle maintained properly
and in accordance 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.
@ 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.
Diesel particulate filter
Ap plies to vehicles: with diesel partic ul ate filter
The diesel particulate filter filters nearly al l of
the soot part icles out of the exhaust. The fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it­
self (for example, because you are only driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter illuminates
c> page 22.
A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system a rea or a fire could
start.
(D Tip s
-When the diesel particulate filter be­
comes saturated, the engine speed in­
creases to approximate ly 1,500 rpm
while the vehicle is in motion to init iate
the cleaning of the diesel particulate fil­
ter a utomatically without the warning
l amp lighting up . If the warning lamp
Dri vin g and en vironm ent 171
Ill sti ll appears, you shou ld drive to a
qualified workshop .
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low -lying parts such as spo ilers and exhaust
system parts do not bottom out and get dam­
aged.
This is espec ially true for veh icles with low­
slung chassis (sports chassis) and fully loaded
vehicles.
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, env ironmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
If you ant ic ipate wha t you need to do next and
drive economically, you can easily cut your
fuel consumptio n by 10-15 percent . This sec­
tion wi ll give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.

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.
