2013 AUDI A5 CABRIOLET brake light

182 Intelligent technology
You can compensate for this slightly reduced
braking power by pushing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warra nty & Maint enance booklet . Failure
to have your brake pads inspected can result in red uced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessa ry wear on the brake system. If you
must use yo ur brakes, do not hold the brakes
down continuously . P u mp the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature and humidity .
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight
condensat ion or after washing your car, the
b rak ing effect can be reduced by moistu re or
ice on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few caref ul
b rake app lications .
At higher speeds and with the w indshield w ip­
e rs turned on, the brake pads press agains t
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for better brake response time under wet condit ions.
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 sa lt coating from brake d
iscs and pads with a few cautio us ap­
plications of the brake
Q ,&. .
Corrosion
The re may be a tendency for dirt to bu ild up
o n the brake pads and corros io n to fo rm on
the d iscs if the car is not driven regu la rly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r 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
c> &. .
Faults in the brak e syst em
If you shou ld no tice a sudden increase in
brake pedal trave l, then one of the two brake
ci rcuits may have fai led
c> &. .
Lo w brake fluid lev el
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake f lu id
level is monitored electronically.
Brake booster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
o n ly when the engine is running .¢
&
Brake lining we ar status
Brake lining wear may be checked by visual in­
spect ion 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 i n­
spect io n ¢
page 249, Changing a wheel.
_&. WARNING
- New brake pads don't have the bes t stop­
p ing power and m ust be "bro ken-in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal city driving.
You can compensate for this by pressing
the brake pedal more firmly. Th is also
applies later when new pads are instal­ led.

-You should perform braking maneuvers
for the purpose of clean ing the brake
system only if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower d riving range . Do not ride
the brakes or hold the pedal down too
long or too often. This cou ld cause the
brakes to get hot and dimin ish braking
effi ciency.
- Do not "r ide the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake. This may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off afte r a few ca re­
f ul brake appl ications.
- Driv ing fo r an ex tended pe riod of time on
salt-covered ro ads w ithout using yo ur
brakes can also affect braking efficiency.
Clean off accumu lated salt coating from
brake discs and pads with a few caref ul
brake applicat ions.
- 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 co uld
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
wor kshop.
- Never let the v ehicle roll to a stop w ith
t he engine shu t off.
Int ellig ent technolog y 183
-If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed conside rably harder to make up
for the lack of booster assistance .
Electro-mechanical
power assist, dynamic
steering
The electro-mechanical power assist helps
the driver when steering .
Power steer ing adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defecti ve! Do not d rive vehicle!
If this indicator light turns on and stays on
and t his message appears, the power steer ing
may have failed .
Do
not con tinue dr iv ing . See your author ized
Audi dealer or other qualified repair facility
fo r ass istance.
f-r,ij Dynamic st eering: System fault! You can
continue driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cu lt to move or more sensit ive tha n usual. The
stee ring wheel may a lso be at an angle when
driv ing straight .
Drive slowly to your a uthorized Audi dea ler or
qualified workshop to have the ma lfunction
correc ted .
fifl Dynamic steer ing: in itializing
If this drive r message appea rs and the indica ­
tor light is flash ing on the instrument panel,
dynamic steer ing * is being rein itia lized. Once
you start the engine after th is is finished, the
steering wheel will be easy to move. Re- init i­
al ization might be necessa ry if the steering
wheel was moved ha rd to the left a nd right
wh ile the vehicle was not moving. The display
goes ou t as soon as initialization is comp lete. .,.

@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmental impact, and
wear on you r engine, bra kes and t ires largely
depend on th ree factors:
= your persona l dr iving style
- operating conditions
- technica l lim itations
I f you anticipate what yo u need to do next and
drive economically, you can easi ly cut your
fuel consumption by 10-15 percent. This sec­
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
@ Tips
The consumpt ion estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depending upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
" Avoid unnecessary accele rat ing and braking.
Dri vin g and en vironm ent 18 9
Vehicles use the most fue l when they a re ac ­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
" Try and keep well below your car's maxi-
mum speed.
Acce lerating gently red uces fue l cons ump­
tion, engine wear, and does not disturb the environment.
Fuel consumpt ion, exhaust emiss ions and en ­
gine noise increase disproportionately at high
speeds . If you drive at approximately th ree
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv­
ing the vehicle.
" Do not warm up the ve hicle by letting the
eng ine run at idle .
It makes sense to shut off the engine in traffic
jams, when wa it ing for tra ins to pass at rail­
road crossings, or at traffic lig hts t hat have
long waits on red . T ur ning the eng ine off for
just 30-40 seconds saves mo re fuel than is
bur ned star ting the e ngine again.
It takes a long t ime for the engine to warm up
fully when it is run ning at idle . However, wea r
and noxious emissions are espec ia lly high
whe n the eng ine is wa rm ing up. So yo u shou ld
drive away as soon a s you start the e ngine and
avo id r unning at high rpms whi le the engine is
still warming up.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 191
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must insta ll ext ended mir ro rs. It is important
t h at you
always have clea r vis io n to the rear .
.8, WARNING
- If a trailer has elec trica l br ake s plea se
no te th at t hese bra kes are not activat ed
by the fa ctory -fit ted control unit -risk of
accident!
- After removing the t railer hi tch, do no t
s to re it in yo ur vehicle . In case of sudden
brak ing, the hitch could fly fo rward and
in ju re you or yo ur passenge rs .
Operating instructions
Maximum traile r we ight
-
A trai ler for your vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution
Be sure the lo ad in the traile r is h eld secure ly
i n p lace to p reven t it from shifting fo rward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ &. in Driving instru ctions on page 19 2.
Engine cooling system
Towing a t railer ma kes t he engine wor k hard ­
er . It is impo rta nt that the cooling system's
perfo rman ce is up to the additional load.
Make sure tha t the coo ling sys tem h as enough
f lu id . .,..

192 Trailer towing
Tire pre ss ure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver 's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Saf ety chains
Be sure tra iler sa fe ty cha ins a re p roperly con­
nected from the trailer to the hitch on the ve ­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it ­
self is no t loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weigh t di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control. A "ba
lanced' ' rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu lt it be­
comes for the driver to control the rig. Do not
drive at t he maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -pa rtic ularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do n ot
try to sto p th e swaying by acc elerating .
Observe speed limits. In some areas, speeds
fo r vehicles tow ing tra ile rs a re lower than for
regular veh icles .
Always apply brakes early. When driving downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . U se of
the brakes alone can cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge c> page 10
must be observed carefu lly. If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
i n t he i nstrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two min utes to prevent he at build-up .
_& WARNING
Anyone not proper ly restra ined in a mov ­
i ng vehicle is a t a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not p roperly wea ring the rest raints
prov ided by Audi.

Your author ized Audi dealer has a variety of
d ed ica ted vehicl e-ca re product s and can ad ­
vise which ones to use for cleaning the exter i­
or and inte rior of your vehicle .
Whether you use products recommended by
Aud i or other commercially ava ilable clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product . Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted.
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail pol ish remover or other volati le
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ignit ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, etc. without pro­
tecting your hands and arms. You may

brakes carefully each time you wash the
veh icle.
@ For the sake of the environment
Select on ly environ mentally friendly clean­
i ng products. Leftover cleaning products
should not d isposed of in the househo ld
waste .
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing . How
often this is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle body, the more lasting their destr uctive ef­
fects wi ll be . High temperatures caused by ex­
pos ure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferably in a professional car wash.

200 Cleaning and protec tio n
The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plas tic ice scraper -better still, a spray
de icer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax s ince these can interfere with
the function of the windshield wiper blades (chatter).
Oi l, grease, or silicone residue can be removed
with
gl ass clea ner or silic on e remo ver. How­
ever, wax residue requires the use of a special­ ly formulated solvent. Please contact your au­
thor ized Audi dealer for adv ice on safe prod­
ucts for wax removal.
W indows shou ld also be cleaned on the inside
at regular intervals.
Never dry windows with the same chamois
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vision through
the w indows.
.&_ WARNING
- Always read and heed all WARNINGS and
other information ~
page 194.
-The windshie ld must not be treated with
water-repellent materials . They can in­
crease glare under poor visib ility condi­
tions such as wetness, darkness, or when
the sun is low on the hori zon. In addi­
t ion, they can cause the win dshield wip­
ers to chatter.
(D Note
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This cou ld cause the g lass to cra ck.
- To preven t damage to the wi res of the
rear defogger, do not place any adhe sive
stickers on the inside of the rear window
ove r the wires .
- To he lp prevent d irt from sc ratch ing the
window, always scrape in a forward di ­
rection -pushing the scraper away from
you -never back and fo rth. -
Water leaking from the ins ide of the rear
windows may damage sensitive electrical components located either under the
rear parcel shelf or in the rear trunk area.
Always ensure that water never leaks
through the body section of the vehicle.
You can do th is by us ing waterproof pro­
tection over the vehicle's electrical com­
ponents (e.g. when install ing window
tinting) .
- Damage or malfunction of elect rical
c ompone nts due to water damage or any
other o uts ide infl uence is not covered by
the A udi New Veh icle Limited Warranty.

Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the w heels with a sponge or hose
brush every other week .
.,. For deep clean ing afterwards, use only a
dedicated
a ci d-free cast alloy wheel cleaner.
.,. Rub a coat of
liqu id w ax onto the rims every
three month. Be sure to reach and treat all
parts of the rim.
To preserve the decorative appearance of the cast alloy wheels, some special care is neces­
sary. In addition to road dirt and salt, brake dust is also corrosive . If left on for too long,
brake dust can cause pitting .
U se only spec ial
acid-free cleaners formulated
for alloy r ims. Safe products are availab le at
your authorized Aud i dealer . Never leave the
cleaner on the rims longer than spec ified on
the label. If not rinsed off promptly, the acid
contained in some cleane rs can attac k the
threads on the wheel bolts .
Never use abrasive o r metal po lish ing clean­
ing agents.
If the protective coating has been
c h ipped, e .g. by kicked up road dirt, touc h it
u p as soon as possible . .,..
