The instrument illumination for the needles
and dials turns on when the ignition is turned
on and the lights are turned off. The illumina ­
tion for the dial s reduces automatically and
eventually turns off as brightness outside in­
creases. This function reminds the driver to
turn the headlights on at the appropriate
time.
Engine coolant temperature gauge
The engine coo lant gauge (D ¢ page 10, fig. 3
only works when the ignition is on. To prevent
damage to your engine, please note the follow­
ing important points:

If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, heavy en­
gine loads and heavy throttle applications .
Normal temperature
The engine has reached its operating tempera­
ture once the L EDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high . This is no need to worry as long as the.
warning light in the instrument cluster does not
ill uminate.
If the LE Ds in the upper area of the
display and the indicator light. in the instru­
ment cluster display turn on, the coolant temper­
ature is too high

!?) Engine speed limitation
(II Maximum engine speed XXXX rpm
The engine speed is automatically limited to the
speed displayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature
range and you have released the accelerator ped­
al.
If the engine speed limitation was activated by
an engine control malfunction, the~ indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam­
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im­
mediately to have the malfunction corrected.
(D Tips
The engine speed is limited when the engine
is cold -the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tachometer moves
to a higher RPM range .
-Engine oil sensor
• Oil level! Sensor defective
If the symbol illuminates, contact your author­
ized Audi dealer and have the oil sensor inspect­
ed. Until you have this done, check the oil level
each time you refuel just to be on the safe side
¢page 207 .
f Engine warm-up request
n Please warm up engine
Fuel has entered the engine oil, either from low
outside temperatures or frequent short drives.
Drive until the engine is warm so that the fuel in

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢&, . The b reak-in pe­
riod can be considerably longe r fo r vehicles with
182
ceramic brake rotors* . You can compensate for
this slightly reduced braking power by pushing harder on the brake pedal. Avoid heavy braking
l oads during the break-in per iod.
Op erating c ondition s and dri ving habits
The brak es on today 's automobiles are still sub ­
ject to wear, depending large ly on operating con­
dit ions and driving habits ¢&, . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads shou ld be
checked by your authorized Audi dealer more of­
ten than specified in the
Warr ant y & Maint e­
nance booklet .
Failure to have your brake pads
i nspected ca n result in red uced b rake perfo rm­
ance.
On steep slopes, you should use the brak ing ef ­
fect of the engine . Th is way, you prevent unnec­
essa ry wea r on the brake system. If you must use
you r brakes, do not ho ld the brakes down contin­
u ous ly. P ump the brakes at intervals.
Operating noi se
Noises may occur when brak ing depending on the
speed, braking force and outside conditions such as temperature and h umid ity.
Due to the nature of the mater ials used in ceram­
i c brake rotors*, no ises may become more appa-
rent at low speeds. ..,.

Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
11-Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consumption, engine wear, and does not disturb the environ­ment.
Fuel consumption, exhaust emissions and engine
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 conditions permit.
Reducing unnecessary idling
Even when your car is just idling i t burns up fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the en-
gine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad crossings, or at traffic lights that have long waits
on red . Turning the engine off for just 30-40 sec ­
onds saves more fuel than is burned starting the
. . engine again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high when
the eng ine is warm ing up. So you should drive
away as soon as you start the engine and avoid
running at high rpms while the engine is still
warming up.
CD Note
Do not leave engine idling unattended after
starting.
If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty.
Driving and the environment
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel .
11-Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs properly and economically. The condition of your vehicle
not only affects its safety and ability to hold its
value, it also affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumpt ion.
This also applies to fuel consumption and eng ine
output .
CD 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 wel l as
improper use of the vehicle w ill 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 components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
11-Try to avoid driving short distances with a cold
engine. .,.
