2012 AUDI A5 COUPE width

-The radar sensor's vision can be reduced
or entirely blocked by rain, snow, and
heavy spray. This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the d irection you
are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, o r vehi­
cles in your blind spot, only after your ve ­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side ass ist signal does not work around
tight corners (turning radius less than
328 feet or 100 m).
- Side assist is no replacement for the driv­
er's full attention . The driver alone is re­
sponsible for lane changes and similar
driving maneuvers. A lways keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
-To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
stickers or bicycle racks).
- Make sure that the signal light on the
outside m irror is not blocked by st ickers
or other items.
@ Tips
- Side assist automatically deactivates if it
detects that the radar sensors are
blocked
9 page 122. The indicator light
on the button goes out .
- The area on the bumper where the radar
sensors are located must consistently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly.
Follow the additional notes on
.:!>page 122 .
-Additional tinting on the front side w in­
dows can make it harder to see and cor­
rectly understand the signal light on the
outside mirror.

Sensor detection area
Applies to vehicles: wit h side assist
t
Fig. 133 Schemat ic illustrat ion : Sensor detect ion area
The detection¢ fig. 133 of the radar sensor
detection area is made up of:
- the approach area (light red area)
(D, about
230 feet (70 m) behind the vehicle, and
- the "blind spot" (dark red area)@.
The radar sensors cover the adjacent left and
right lanes. Other lanes are
not covered by the
radar sensors.
(D Tips
Side assist does not measure actual lane
width. The system assumes a fixed lane
width . Detection in the left and right lanes
i s based on this assumed lane width .
When driving on narrow roads o r when
driving to the left or right of the center of
a travel lane, it is possib le that vehicles
will be detected that are
not in the lane
next to the lane you are using
¢page 121.
Operation
App lies to vehicles: wit h side assist
Side assist compares the distance and differ­
ence in speed of detected vehicles with the
speed of your vehicle . Whenever the differ ­
ence in speed and distance is registered as no·
table if you were to change lanes, a signal
light appears on the respective m irror.
Ill-

Setting the signal brightness on the
outside mirror
Applies to vehicles: with s ide assist
The signal brightness can be set in the radio
orMMI* .
~ Select: Function button ICARI > Audi side
assist -lamp .
~ Rotate the control knob to adjust the dis­
played brightness of the signal light on the
outside mirrors.
The brightness of the signal light for both the informational and alert stages is automatical­
ly adjusted to ambient light conditions . In ad­
dition, you can adjust the
basic brightness
separately, via the brightness function.
While making the adjustment, the new brightness setting is displayed briefly . The
brightness displayed is that of the informa­
tional stage signal. The alert stage signal
brightness is linked to the informational stage
signal brightness.
The informational stage signal brightness
should be adjusted so that you notice the sig­
nal illumination when you look in the outside
mirror, but not when you look forward
through the windshield .
In very dark or light surroundings , the auto ­
matic brightness setting adjusts signal light
brightness to maximum or minimum intensi­
ty, as needed. In circumstances such as these,
you may not notice any change in the bright­
ness on the outside mirror when adjusting the
basic brightness.
You may not notice the change until lighting
conditions are normal again .
@ Tips
-Side assist is not active when the basic
brightness is adjusted . The signal light
comes on briefly to help you make the
adjustment .
- Your settings are automatically stored
and assigned to the remote control key
being used .

General information
Applies to vehicles: with side assist
Side assist has limits and cannot detect vehi­
cles under all road and weather conditions.
Please remember system limitations and nev­
er rely on the system , especially when :
- driving through curves
~page 121,
-lanes are of different widths ¢ page 121.
When driving through curves
Applies to vehicles: with side assist
Side assist cannot detect vehicles in curves
with a turning radius of less than 328 feet
(100 m).
When driving through a curve, it is possible
that side assist may register a vehicle two
lanes over, and the signal on the outside mir­
ror will light up.
Lane width
Applies to vehicles: with side assist
Fig. 138 Lane s of a normal wid th are in detectio n area
Fig. 139 Narrow la n es: S ide assist may detect vehicles
two lanes away
Side assist's detection area is designed to cov­
er lanes of standard width to the left and
right of your travel lane, depending on ..,.

122 Audi side assist
whether you drive in the center of your lane or
closer to the edge.
If you d rive in narrow lanes, side assist's de­
tection area may also incl ude other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 139. Under these conditions,
ve hicles can also be detected that are two
lanes away, and side assist then could switch
between the informat ional and warn ing stage
signals .
When dr iv in g in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area.
Notes
Messages in instrument cluster display
Applies to vehicles: with side assist
If side assist turns off automatically, the indi­
cator light on the button wi ll go out and you
will see a message in the instrument cluster
d isplay:
Audi side assist not available : sensors
blocked
The s ide assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢page 116, fig. 130. To ensure
that you do not adversely affect the way side
assist funct ions, foreign objects (such as st ick­
e rs or b icycle racks) should not be attached to
the area on the rear bumper where the sen­
sors are located. If side assist functions are
adversely affected, you will see this message
in the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no ve hicl e is detected for a longer period of
time while driving , side assist will also switch
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
vehicle's batte ry charge being low), s ide ass ist
cannot be activated temporarily .
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Safety tips
Applies to vehicles: with side assist
The side assist detection may be limited when
driving aro und narrow street corners, on hilly
streets, and under poor weather conditions.
It is possible that the radar sensors may a lso
detect other objects, such as high or stag­
gered guardrails.
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
on this assumed lane width. When driving on
narrow roads or when driv ing to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
-
- I mproper reliance on the side assist sys-
tem can cause collis ion s and serio us per­
sonal injury:
- Never rely on ly on s ide assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Side assist cannot detect vehicles in time
to a lert you when they approach from
behind at very high speed, or fall drop
back very qu ickly.
- The radar sensor's
vision can be reduced
or entire ly blocked by rain, snow, and
heavy spray. This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you
are traveling and the relevant area
around the vehicle.

254 Tires and wheels
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressu re
to which a tire may be inflated. Also called
"maximum inflation p ressure."

Occupant distribution means distribution of occupants in a vehicle .
Outer diameter means the overa ll diameter of an inf lated new
tire.
Overall width
means the linear distance between the exteri­
ors of the sidewalls of an inflated tire, includ­
ing e levations due to labeling, decorations, or
protective bands or ribs.
Ply
means a layer of rubber-coated parallel cords.
Production options weight
means the comb ined weight of those installed
regular production options weighing over 5
lbs . (2 .3 kg) in excess of those standard items
which they replace, not previously considered
in curb weight or accessory weight, including
heavy duty brakes, r ide leve lers, roof rack,
heavy duty battery, and specia l trim .
Radial ply tire
means a pneumatic tir e in which the p ly cords
that extend to the beads are laid at substan­
tially 90 degrees to the centerline of the
tread . Recommended inflation pressure
see
~
page 253, Cold tire inflation pressure.
Reinforced tire
means a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire. Reinforced tires
may be identified as "XL", "xl", "EXTRA LOAD",
o r "R F" on the sidewall.
Rim

ratings range from 93 mph (150 km/h) to
186 mph (298 km/h)
~ page 264 . You may
not find this information on all tires because
it is not requ ired by law.
The speed rating letter code, where applica­
ble , is molded on the tire sidewall and indi­
cates the max imum perm issible road speeds
~ A in Winter tires on page 268.
Tire pressure monitoring system*
means a system that detects when one or
more of a veh icle's tires are underinflated and
illuminates a low tire pressure warning tell­
tale.

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

26 6 T ire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radial
tires of the same type, size (roll ing c ir­
cumference) and the same tread pattern.
Driv ing with different ti res reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare t ire is not the same as the
t ires that are mounted on the veh icle -
f or example with winte r tires -on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the nor­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maximum speed for which the tires on your veh icle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading t ires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
poss ible to use wheels from other vehi­
cles -in some cases not even whee ls
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision.
0 Note
- For technical reasons , it is not general ly
possib le to use the whee l rims from oth­
er vehicles . This can ho ld true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve- hicle (fo
r example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possib le.
- Never drive without the valve stem cap.
The va lves could get damaged.
@ For the sake of the env ironment
D ispose of o ld tires in accordance with the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality g rades can be found where applicab le
on the tire side wall between tread sho ulder
and maximum section width
~ page 263,
fig . 214.
For exampl e: Tread wear 200, Trac tion AA ,
Tempe rature A.
All passenge r car t ires must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread w ear
The tread wear grade is a comparative rating
based on the wear rate of the t ire when tested
under controlled conditions o n a specified
government test course.
For example, a tire graded 150 would wear
one and one ha lf (1 1/2) times as well on the
gover nment course as a ti re g raded 100 .
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depart s ignificantly from the
no rm due to va riations i n driving hab its, se rv ­
ice practices and differences in road charac ter­
istics and cl imate.
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the ..,.

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 . .., •
