A WARNING
You should only switch sport mode on or
switch ESC/ ASR off if your driving abilities
and road conditions permit.
bility
- The stabilization function is limited when
sport mode is sw itched on. The driving
wheels co uld spin and the vehicle could
swerve , espec ially on s lick o r slippery road
s u rfaces.
- The re is no vehicle stab ilizat ion when ESC/
ASR a re swi tched off .
(D Tips
-ESC/ASR cannot be switched off or sport
mode cannot be switched on if the cru ise
control system* or the adaptive cruise con
tro l* is switched on .
- If the rear spoiler system malfunct ions,
sport mode may not switch on or it may switch off ag ain automatically .
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. ..,.

Effect of wat er and road salt
In ce rtain situations, for example after driving
through water, in heavy rain, afte r ove rnight con
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first w ith a few careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. Th is occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coat ing from brake discs
and pads with a few cautious applications of the b rake ¢_&. .
Due to their surface character istics, ceramic
brake roto rs* absorb mo isture in such condit ions.
This can cause a temporary reduc tion in braking
force compared to dry brakes. You can compe n
sate fo r th is by press ing the b rake peda l harder.
Corrosion
There may be a tende ncy for d irt to bu ild up on
the brake pads and corros ion to form on the discs
if the car is not dr iven regularly or only fo r sho rt
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro
sion has formed on the discs, it is adv isable to
clean off the pads and discs by brak ing firmly a
few t imes from a mode rately h igh speed ¢,& .
Faults in the brake system
If you should notice a sudden increase in brake
pedal travel, then one of the two brake c ircuits
may have failed
¢ ,& .
Low brake fluid le vel
Malfunct ions can occur in the brake system if the
brake fl uid level is too low. The brake fluid level
is monitored electronically .

_8 WARNING "'----
-New b rake pads don't have the best stop
p ing power and must be "broken-in" d uring
the initial 250 miles (400 km). The b reak-in
period can be considerably longer for
veh icles with ceramic brake roto rs*. You can
compensate for this by pressing the brake
pedal mo re firmly. This also applies late r
when new p ads are inst alled.
- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit io ns pe rmit. O ther ro ad
users m ust no t be put at r is k - you may
cause an accident!
- Before descending a steep g rade, reduce
speed and shift transmission into a lower
gear o r lower driving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This cou ld cause t he b rakes to get
hot and dimin ish braking effic iency.
- Do not " ride the brakes" by rest ing your foot
on the pedal when you do not intend to brake. This may cause the brakes to over
heat, premature wear and increased stop
p ing distance .
- Unde r certain climatic and ope rating condi
tions such as passing t hrough water, d riving
i n heavy rain o r afte r wash ing the veh icle,
the effectiveness of the brakes ca n be re
duce d. In winter, ice can accum ulate on the
b rake pads, lin ings, discs and dr ums. Care
fu lly apply brakes for a test. Brakes will d ry
an d ice coatings will be cleaned off after a
few ca refu l brake applications.

~ Turn the jack handle counter-clockwise to lower
the vehicle until the jack is fu lly re leased.
~ Use the wheel bolt wrench to tighten all wheel

(D Tips
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bo lts.
- Pu ll the reversible blade from the screwdriv
er before you use the hexagonal socket in
the handle to turn the wheel bo lts.
- When mounting tires w ith

make sure the tread pattern is
po inted the r ight way ¢

-The wheel bolts should be clean and easy to
turn . Check for d irt and corrosion on the
mating surfaces of both the wheel and the
hub . Remove all dirt from these surfaces be

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
Using a repl acement t ire w ith a tread pattern
intend ed for use in a sp ecific direction
When using a rep lacement tire with a tread pat
tern intended for use in a spec ific d irection ,
please note the follow ing:
- The direction of rotation is marked by an arrow
on the side of the tire .
- If the replacement tire has to be installed in
the incorrect direction, use the replacement tire only temporarily s ince the t ire w ill not be
ab le to achieve its optimum perfo rmance char
acter istics with rega rd to aquap lan ing, no ise
and wear.
- We recommend that you pay pa rt icu lar atten
tion to th is fact d uring wet weather and that
you adjust your speed to match road cond i
tions .
- Rep lace the flat tire w ith a new one and have it
installed on your veh icle as soon as possib le to
restore the hand ling advantages of a unidirec
tional tire.
Notes on wheel changing
Please read the information ¢ page 225, New
tires or wheels
if you a re go ing to u se a replace
ment t ire wh ich is different from the t ires on
you r vehicle .
After you change a tire:
- Check the tire pre ssure on the r epl acement
tire immed iatel y afte r in st a llat ion .
- Have th e whe el bolt tight ening torqu e
c hecked with a torque w rench as s oon as pos
s ible b y your authorized Audi de aler o r a
qualified ser vice st ation.
- With steel and allo y wheel rim s, the wheel
bolt s are co rr ectl y ti ghtened at a torque of 90
ft lb
( 1 20 Nm) .
-If you notice that the wheel bolts are corroded
and diffi cult to turn while changing a ti re ,
the y should be r eplaced before you chec k the
tightening torque. ..,.
