Braking
What affects braking efficiency?
New brake pad s
During the f irst 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢.&. . The break- in pe­
riod can be considerab ly longer for vehicles w ith
ceramic b rake roto rs*. You can compensate for
this s light ly reduced b ra ki ng power by push ing
ha rder on the b rake peda l. Avoid heavy braking
loads during the bre ak-in period.

Operating conditions and driving habits
The bra kes on today's automobiles a re s till sub­
j ect to wear, depend ing largely on operating con ­
ditions and driving habits ¢& . On vehicles that
a re either driven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Aud i dealer more of­
te n tha n specified in the Warranty
& Maint e­
nance bookl et. Failure to have you r brake pads
i nspected can resu lt in reduced b rake pe rform­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine . This way, you prevent un nec­
essary wear on the brake system . If you must use
you r brakes, do not hold the bra kes down cont in­
u o usly. Pump the brakes at in tervals.
Operating noise
Noises may occur when braki ng depending on the
speed, braking force and outs ide cond it ions such
as tempera ture and hum idity.
Due to the nature of the materia ls used i n ceram­
i c brake rotors*, noises may become more appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water , in heavy rain, after overnight 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
dr ied fi rst w ith a few careful b rake app lications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the brake r otors for a short amount of time. This occurs at
r egular intervals without the dr iver not ic ing and
provides fo r be tter brake response time under
wet cond it ions.
The effect iveness of the brakes ca n be red uced
when the v ehicle is d riv en on a salt-cove red road
and the b rakes are no t used. Likewise, you clean
off a ccumula ted salt coating from b rake d iscs
and pads with a few ca utious app lications of the
brake ¢& .
D ue to the ir sur fa ce character istics, cerami c
brake ro tors * absorb moistu re in such co ndi tions . ..,.

r-­N "': ..... \!) 1.1'1
N 1.1'1 .....
This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake pedal harder.
Cor ro sion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to fo rm on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the b rakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
c:> &. .
Faults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have fai led
c:> .&, .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if the
brake fluid level is too low. The brake flu id leve l is
monitored e lectronically.
Br ake power assis t un it
T he brake power assist unit increases the pres­
sure that you generate with the brake pedal.
It
works only when the eng ine is running .
Brak e lining wear sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 203 .
.8, WARNING
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the init ial 250 mi les ( 400 km) of normal city
driving. The break -in period can be consider­
ably longer for vehicles with ceramic brake
rotors *. You can compensate for this by
pressing the brake pedal more firmly. This
also applies later when new pads are instal­
led .
- You should perform brak ing maneuvers for
the purpose of clean ing the brake system
Int elli ge nt te chn olo gy
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the bra kes 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, premat ure wear and increased stop­
ping distance.
- Under certain cl imatic and operat ing condi ­
tions such as passing thro ugh water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, lin ings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can also affect braking efficiency .
Clean off accum ulated salt coating from
b rake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be su re the air flow
to the front brakes is not obstructed . O ther­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem .
- Fai lure of one brake circuit will impai r the
braking capability resu lting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest Aud i dea ler
or qualif ied workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, for ex­
ample when towing your veh icle, or because
the brake booster has somehow been dam­
aged, the brake pedal must be pressed con ­
siderably harder to make up for the lack of booster assistance.

Driving and en vironment
Driving and environment
Break-in period
A new vehicle must be broken in, and the break-in
period shou ld be 1 ,500 miles (2,500 km) . Do not
use full acceleration for the first 600 miles
(1 ,000 km) and do not exceed the maximum en­
gine speed of 6,000 rpm You must also not use
full accelerat ion between 600 and 1,200 miles
(1,000 to 2,000 km) . From 1,200 to 1,500 miles
(2 ,000 to 2,500 km), you can gradually increase
maximum eng ine speed to 8,250 rpm for brief
pe riods.
During the first hours of operation, there is
greater fr iction in the eng ine and the transmis­
sion than later when all the moving pa rts have
b roken in .
The way you drive during the first 1,500 miles
(2 ,500 km) affects engine quality . If you drive at
modera te engine speeds thereafter, part icu larly
when the engine is cold, yo u red uce eng ine wea r
and increase the potential mileage o f the engine.
Do not dr ive at RPMs that a re too
low. Shift down
when the engine is no longe r runni ng "smooth­
ly". Extremely high RPMs are gover ned automati­
cally.
Avoid damaging the
vehicle
W hen you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
This is especially true for vehicles with low-slung
chassis (sports chassis) and fully loaded vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
d riving through water, for examp le on flooded
roads:
- The water must no t be any h igher than the bot­
tom of the vehicle body.
142
- Do not drive faster than walk ing speed .
A WARNING
After driv ing through water, mud, s lush, etc .,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by brak ing carefully to restore the full
braking effect.
(D Note
Vehicle components such as the eng ine,
transmission , suspension or e lectrical system
can be severe ly damaged by dr iv ing t hrough
water .
(D Tips
- Check the dept h of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or switch the engine off when driv ing through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to d rive
through safely .
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmen tally sound manner.
.,. Always use lead-free gasoline ~ page 151,
Fuel supply.
.,. Never r un the tank down all the way to empty.
.,. Never put too much mo tor o il in yo ur engi ne
~ page 160, Adding engine oil 'l::r..
.,. Never try to push- or tow-sta rt your vehicle .
The cata lytic converter is an effi cien t "clean -up"
device built in to the exhaust system of the vehi ­
cle. The cata lytic conve rter burns many of the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.

Vehicle care and cleaning
A WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. The bra kes
must be dried first with a few caref ul brake
applications .
@ Note
-If you wash the ve hicle in an au tomatic car
wash, you must retract the extend able rear
spoi ler * if necessary, and fold the exterior
mirrors in to reduce the risk of damage .
Power folding exterior mirrors* must only
be fo lded in and out using the power folding
funct ion.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
- To red uce the risk of damage, do not wash
the power top with a pressure washer. -
To reduce the risk of damage, do not wash
decorative decals * with a pressure washer.
- T o reduce the risk of damage to the surface,
do not use insect remov ing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polish ing agents or hard
wax.
- Never use car wash cycles that apply pro­
tective wax. It can destroy the matte fin­ ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith matte
finish paint. The pa int could be damaged
when the stickers o r magnets are re­
moved.
- Do not wash the vehicle using cleaning
products that contain alcohol when the en­
gine is hot. This increases the risk of dam­
age to plastic components, such as cracking.
@ For the sake of the environment
Only wash the vehicle in facilities spec ial ly de­
signed for that purpose. This w ill reduce the
risk of dirty water contaminated with oil from
entering the sewer system .
