18 Instrum ent s and w arn ing /indic ato r light s
BRAKE/ CQ)) Brake system
The warning/indicator light flashes if brake
fluid level is low, if there is an ABS system
malfunction or a parking brake malfunction.
The 1111 (USA models)/ . (Canada models)
light illuminates when the ign ition is turned
on .
It goes out after the engine has been
started. This indicates t hat the brake war ning
light is funct ion ing properly.
If th e br ake w ar ning light d oes not light up
w hen the engin e is c ranking , th ere ma y be a
ma lfun cti on in th e ele ctric al sys tem. In thi s
case, c ontact an auth oriz ed Audi d eale r.
If the brake system warning/ind icator light
flashes, there is a brake system malfunction .
By pressing the
ISE TI button, you can br ing up
a driver message which exp la ins the ma lfunc­
tion in more detail
Q page 30.
If the ABS fails, the ABS warning/ind icator
light
B (USA mode ls)/ 11] (Canada mode ls)
flashes together w it h the brake system warn­
ing/i ndicator light
Q & .
(USA models): If the 1111 warn ing light and
the
El warning light illuminate togethe r, im­
mediately contact your author ized Audi dealer
or qualified workshop to have all bra ke pads
inspected
q page 34 .
When the light comes on, an audib le warni ng
signal is also give n.
A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light
II]
come on together, the rear wheels could
.
lock up first under hard braking . Rear
wheel lock-up can cause loss of vehicle
control and an accident . Have your vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied repair
facility and have the brake system in·
spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You must allow fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

Driver information messages
Driver information messages are shown in the
instrument cluster display in addition to sym­
bols.
Fig. 25 Instrument cluster: SE T butto n
For example, if the transmission selector lever
is not in the
P position when the engine is
turned
off, the following message appears:
Shift to P, otherwise vehicle can roll away.
Doors do not lock
if lever is not in P.
The ignition key can on ly be removed with the
selector in this position. This and other mes­
sages are brought up if a function cannot be
carried out.
Driver messages and red symbols
If a red symbol appears in the display, a dr iver
message is a lso displayed automatica lly.
For example, the. symbol for a problem
with engine oil pressure appears in the dis­
play . The message :
Switch off engine and check oil level
The driver message in the display goes out af­
ter about
5 seconds . The driver message can
be disp layed again by brief ly pressing the
ISETI button i=> fig. 25.
Driver messages and yellow symbols
If a ye llow symbo l appears in the disp lay, a
driver message is also displayed automatica l­
l y.

A WARNING ,~
The increased safety afforded by ASR does
not mean that you can take safety r isks .
Always adapt your driv ing style to the road
conditions and traffic situation .
@ Tips
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling radius of
the t ires can cause the system to reduce
engine power when this is no t des ired. See
also ¢
page 263, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat ­
ing conditions and dr iving habits ~.&. . On ve­
h icles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your a uthor­
ized Audi dealer more often than specified i n
the
Warranty & Maintenan ce booklet . Failure
to have your brake pads inspected can result
in red uced brake performance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you p revent un­
n ecessary wea r on the brake system . If you
must use you r brakes, do not ho ld the bra kes
down continuously . Pu mp the b rakes at in ter ­
va ls.
Noises may occur when braking depending on
the speed, bra king for ce and outside condi­
tions s uch as temperatu re a nd humidity .
Moisture or road salt
If you are driving faster than 31 mph (SO km/
h) and the windsh ie ld w ipers are on, the brake
pads will briefly touch the b rake d iscs in regu­
l ar i nte rva ls so as to imp rove reaction t ime
Int ellig ent technolog y 207
when b rak ing on wet surfaces . You, the driver,
will not notice anything.
U nder certa in cond itions , fo r example, when
d riv ing th rough wa ter or very heavy ra in , or
even after washing your veh icle, 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 red uced
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 w ith a few careful
applications of the brake¢,&. .
Corrosi on
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly for short trips w ith litt le use of the
brakes .
If the brakes are no t used frequently, or if cor­
ros ion has formed on the discs, i t is adv isable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high speed ¢,& .
Fault s in the brake s ystem
If you should notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢,&. .
Lo w br ake fluid le vel
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake lining wea r status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for th is in­
spection ¢
page 2 74, Changing a wheel.
•
•

This automatic adjustment process will cause
a
slight vib ra tion of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traffic condi­
tions.
A WARNING
Although the ABS is very effective, always
remember that braking capability is limit­
ed by t ire traction . A lways adjust your dr iv­
ing speed according to the road and t raff ic
conditions. Do not let the extra sa fety af­
forded by the ABS tempt you into taking
extra risks. The ABS cannot overcome the
laws of physics .
(D Tips
-If ABS is not functioning properly, a
warning light will come on . See
~ page 16.
-If a fault occu rs in the ABS, the EDL is al­
so not functioning . This is indicated by
the ABS warning light .
Brake assist
Brake assist is designed to achieve the opti­
mum broking effect.
Brake assist helps to increase the effective
brak ing power and thus to achieve a shorter
stopping distance. If the driver presses the
brake peda l very quick ly, brake assist auto­
mat ica lly boosts the braking force to the max­
imum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop
the wheels from locking . You should then
keep the brake pedal pressed u ntil the vehicle
has braked to the required speed . Brake ass ist
sw itches itself off as soon as you release the
b rake peda l.
A WARNING
Please remembe r that the accident r is k al­
ways increases if yo u drive too fast, espe ­

advanced power
steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
T he advanced Servotronic ® power steer ing
system senses the road speed and elect ron i­
ca lly adjusts power assistance to provide com­
fortab le and safe ste ering response exact ly
matched to the vehicle speed .
Power steering will not work i f the engine is
off. As a result, the stee ring wheel will be hard
to turn .
T he power steering fluid level is checked d ur­
ing the schedu led maintenance services .
(D Note
If there is an e lectronic malfunction, ser ­
votronic
will s till function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most noticeable when turning the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
q uired than usual.
- Be aware of the different than usual
steering response and adjust your steer ­
ing force acco rdingly .
- Have the problem checked and set right
by an Audi dealer as soon as possible.
(D Tips
-Whe n the engine is running, never hold
the steering w heel turned all the way to
the rig ht or to the left for longer t han 15
seconds. The powe r steering pump will
overheat the hydraulic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system .

218 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Trailer hitch Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
¢ A.
Trailer brakes
If your trailer is equipped with a braking sys­
tem, check to be sure that it conforms to all
regulations . The trailer
hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A.
Safety chains
Always use safety chains between your vehicle
and the trai le r.
Trailer lights
T railer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors . It is important
that you
always have clear vis ion to the rear.
,8. WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
