- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant.
Q) Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo ile r has been designed to
proper ly distrib ute the cooling air wh en
t h e veh icle i s moving.
If the spoiler is
damaged, this cou ld red uce the cooling
effect and the engine co uld then over ­
heat . Ask yo ur authorized Audi dea ler fo r
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine R PM drops be low 1 ,500, you should
downshift to the next lower gea r. T he red area
at the end of the sca le indicates maximum
pe rmissib le engine RPM after the break- in pe­
riod. Before reach ing this area, move these­
lector lever to position "D/S (Drive)" or ease
your foot off the accelerator peda l.
(D Note
The tachometer needle should only br iefly
be in the red zone: you cou ld damage your
eng ine! The beginn ing of the red zone var­
ies depending on the e ng ine.
@ For the sake of the environment
Upshift ing early saves fuel and reduces en­
g ine noise.
Fuel gauge
The fuel gauge only wo rks when the ignition is
on .
If the fuel level drops below 2.6 gallons (10 liters), the bottom LED turns red and the
indicator
light~ turns on ¢
page 20. The
bottom LED blinks red when the fue l level is
very low.
T he possible range based on the current f uel
level is shown in tab@¢
page 22, fig . 4 .
(D Note
Neve r run the tan k comp letely dry. An ir­
r egular supp ly o f fu el can cause engine
misfiring and fuel could enter the exha ust
system . The cata lytic converter could then
overheat and be damaged.

The rear spoiler may not have extended due to
a ma lf u nction. This could change the vehicle 's
driving characteristics at high speeds . Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immed iate ly to have the
malfunction corrected. The co lor of the indica­
tor light depends on the ve hicle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear

Braking
General information
What affects braking efficiency?
Ope rating condition s and dri ving h abit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve­
hicles that are either dr iven mostly in stop­
and-go c ity traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often th an specified in
the
Warran ty & Maintenan ce boo klet. Failure
to have yo ur brake pads inspected can result
in reduced brake performance .
On steep slopes, you sho uld use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the b rake system. If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Mo istur e or road salt
U nder certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered

road and the brakes are not used. Here too,
you should clean
off accumulated salt coating
from brake discs and pads with a few careful applications of the brake
i:> ,&. .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the
brakes .
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed
i:> .&. .
Faults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have failed
i:> ,&. .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
Brake booster
The brake booster works with vacuum pres­
sure which is created only when the engine is
running
c> .&. .
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection
c> page 254, Changing a wheel.
,8. WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride the brakes or hold the pedal down too
long or too often . This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned
off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with
the engine shut
off.
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
