190 Intelligent technology
differential lock (EDL), dynamic steering* and
selective whee l torque control. ESC is switch­
ed on all the t ime. In certa in situations when
you need less traction, you can switch off ASR
by pressing the button
[ill c> page 191,
fig. 180. Be sure to switch ASR on again when
you no longe r need less traction .
Anti-loc k br ak ing system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard brak ing. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to b rake the vehicle.
B rake as sist sys tem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quick ly in emer ­
gency situations. You must p ress and hold the
b rake pedal until the situation is over. I n
vehicles w ith adaptive cru ise cont rol*, the
b rake assist system is more sens it ive if the
d istance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the d rive
wheels begin to spin and ad apts the fo rce to
the road condit ions. This makes i t easier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the d rive powe r to the other d rive
wheel o r whee ls if the vehi cle is equipped wi th
a ll-w hee l drive* . This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automat ica lly swit ches
off to help keep the brake o n the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
norma l.
Dynamic steering*
On vehi cles w ith dy namic stee ring*, ESC helps
stabilize the steering i n critical s ituations.
Selective wheel torque control
T he sele ctive whee l torq ue con trol ope rates
when driving through c urves . The front whee l
on the inside of th e curve o r both wheels on
the inside of the curve are braked selectively
as needed. This minimizes sliding in the front
whee ls and allows for more precise driving
t hr ough curves. The appl icable system may
not act ivate when dr iv ing in wet or snowy con­
ditions .
,&. WARNING
-ESC, ABS, ASR, EDL, dy namic steeri ng*
and the select ive wheel torq ue con trol
c a nnot ove rcome the laws of physics.
T his is especially important on slippery
or wet roads.
If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic
and wea ther conditions. The risk of los­
ing con trol of t he vehicle increases when
d riving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, ASR, EDL, dynam ic steering* and
the selective wheel torque contro l can­
not prevent collisions .
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin eve n w ith
these assistan ce systems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheels are equipped with identi­
cal tires. D iffe ren t tire si zes can lead to a
reduction in engine power.

always r ead and heed all W ARN­
ING S ~ A in Working in the engine compart­
ment on page 213.
.. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 192, ~ page 215,
fig . 188.
The brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The location of the brake fl uid reservoir can be
seen in the engine compartment illustration
¢page 215.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
If the brake fluid level falls considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light
1111 (U .S . models)/ . (Canadian
models) will come on
~ page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
f ied fac ility and the cause corrected . If the
b rake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
hi gh, cor rosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerab ly and
decrease braking performance.
Therefore, the brake flu id must be changed
ev ery two ye ars. A lways use new b rake fluid
which confo rms to Federal Motor Vehicle
Standard "FMVSS
116 DO T 4".
The brake flu id rese rvoi r ca n be difficult to
r each, therefo re , we recommend that yo u
h ave the brake fl uid changed by you r autho r­
i zed
Audi de aler . Your dea le r has the correct
Checkin g and fillin g 223
tools, the right brake fl uid and the know -how
to do this for you .
A WARNING
-Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only b rake fluid tha t meets SA E
spe cificat ion
J 17 03 and conforms to
Federa l Moto r Ve hicl e Standard
116.
Always check with your authorized Audi
dealer to make sure yo u are using the
correct brake fluid. The correct type of
brake f luid is also ind icated on the
brake f luid reservoir .
- The brake fluid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the brake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accident.
(!) Note
Brake fluid will damage the paint of your
vehicle.
@) For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that you have th e brake flu id
changed by you r autho rized Aud i dea le r.
Battery
General information
Under normal operating cond itions, the bat­
tery in your Audi does not need any ma inte­
nance . With
high outside temperatu res or
lo ng da ily drives we recommend that you have
the e lectrolyte leve l che cked by a se rv ice fa­
c il ity. The ele ctroly te leve l should also be
chec ked each t ime the battery is cha rged

224 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons¢
& in Re­
pair, core and disposal of the airbags on
page 158.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for l ong period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab il ity over a longer period
¢
page 195. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights or power seat adjus tment. The conven­
ience f unctions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
D uring the winter months, ba tte ry capaci ty
tends to decrease as tempe rat ures d rop . This
is because more powe r is also consumed while
starting , and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticular ly in c ity traffic or when t raveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 226. A we ll
charged battery w ill not only prevent starting
prob lems when the weather is cold , but w ill
also last longer .
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from be ing damaged and having
to be replaced .
