2012 AUDI A5 COUPE wheel bolts

The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mir­
rors.
The windows must not be cleaned with insect
remover or wax sin ce these can interfere with
the function of the windshield wiper blades
(chatter).
Oil, grease, or silicone residue can be removed
with
glass cleaner or silicone remover. How­
ever, wax residue require s the use of a special­
ly formulated solvent. Please contact your au­
thor ized Audi dealer for advice on safe prod­
ucts for wax removal.
Windows should 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 windows.
A WARNING
-Always read and heed all WARNINGS and
other information
r::.> page 221.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di­
rection -pushing the scraper away from
you -never back and forth.
Cleaning and protection 225
-Water leaking from the inside 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 this by using waterproof pro­ tection over the vehicle's electrical com­
ponents (e.g. when installing window
tinting) .
- Damage or malfunction of electrical
components due to water damage or any
other outside influence is not covered by
the Audi New Vehicle Limited Warranty.

ranty.
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the wheels with a sponge or hose
brush every other
week .
.,. For deep cleaning afterwards, use only a
dedicated
acid-free cast alloy wheel cleaner.
.,. Rub a coat of
liquid wax 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.
Use only special
acid-free cleaners formulated
for alloy rims. Safe products are available at
your authorized Audi dealer. Never leave the
cleaner on the rims longer than specified on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the wheel bolts.
Never use abrasive or metal polishing clean­
ing agents. If the protective coating has been
chipped, e.g. by kicked up road dirt, touch it up as soon as possible . .,..

comb inat ions can lead to loss of control,
col lis ion and serious personal injury.
- Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- installed tires or other combina ­
tions that have been specifically ap­ proved by the vehicle manufacture r.
- Tires age even if they are not being used
and can fail sudden ly, especially at high

speed before driving off . Never drive faster
than the speed permitted for your specific
winter t ires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers .
A WARNING
Driv ing faster than the maximum speed
for which the w inter t ires on your vehicle
were designed can cause tire fa ilu re in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per ­
sonal injuries. Have worn or damaged tires
rep laced immed iate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster t han the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winte r tires and all -wheel
drive tempt you into taking extra r is ks. Al­
ways remembe r:
- When brak ing, an all -wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
canno t he lp under black ice condit io ns.
@ For the sake of the environment
Use summer tires when weather cond i­
tions permit . They are quieter, do not wea r
as quickly and reduce fue l consumption .
Snow chains
Snow chains may be fitted on ly to the front
wheels, a nd only to certa in tire sizes. Ask yo ur
author ized Audi dealer on wh ich tire sizes
snow chains can be used. The snow chains must have
low -profile links
and must not be thicker than 0 .53 inch
(13.S mm), includ ing the lock.
Remove whee l cen ter cove rs and t rim discs
before putting snow chains on your vehicle
¢ 0 . For safety reasons cover caps m ust then
be fitted over the wheel bolts. These are avail ­
a ble from authori zed Aud i dealers.
A WARNING
Using the wrong snow chains for your veh i­
cle o r instal ling them incorrectly can in ­
crease the risk of loss of cont rol leading to
serious pe rsonal injury .
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions p rov ided by t he snow cha in
manufac turer.
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specifi c snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains down un necessa rily .
- Snow chains, which come into direc t con­
tact with the whee l rim, can scratch or
damage i t. Therefo re , make sure tha t the
snow chains are s uitably covered. Check
t he pos ition of t he snow chains after
driving a few yards and correct if neces ­
sary. Follow the inst ructions from the
snow chain man ufacturer when do ing so.
(I) Tips
Where snow chains are mandatory on cer ­
tain roads, th is normally a lso applies to ve ­
hicles w ith all whee l dr ive .

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 295.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 258, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •
