2017 AUDI A3 SEDAN width

Assistance systems
warn you about detected vehicles that it has clas­
sified as critical.
@ Tips
You can adjust the brightness on of the dis­
play on the rearview mirror¢
page 141.
General information
App lies to: ve hicles w ith Audi side assist
@
Fig. 146 Driving s it u ations
Fig. 147 Rear of the veh icle: pos it ion of the sensors
Side assist functions at speeds above approxi­
mately 9 mph (15 km/h) .
@Approaching vehicles
In certain cases, a vehicle will be classified as
critical for a lane change even i f it is still some ­
what far away. The faster a vehicle approaches,
140
the sooner the display in the exterior mirror will
turn on .
@Vehicles traveling with you
Vehicles traveling with you are indicated in the
exter ior mirror if they are classified as critical for
a lan e change . All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles you are passing
If you slow ly pass a vehi cle that side assist has
detected (the differe nce in speed between the
vehicle and your vehicle is less than approximate­
l y 9 mph (15 km/h)), the disp lay in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
The display wi ll not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed is greater than approximate ly 9
mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the lef t
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior m irror may turn on even though
there is no vehicle located in the area that is criti­
ca l for a lane change. For example:
- If the lanes are narrow or if your
are dr ivin g on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is
not adjacent to your cur rent lane.
- If you are driving through a curve. Side ass ist
may react to a vehicle that is one lane over
from the adjacent lane.
- If side assist reacts to other objects (such as
high or displaced guard ra ils).
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar
sensors ¢ fig. 147 with
stickers, deposits, bicycle wheels or other ob ­
j ects, because they will impair the function. Do
not use s ide assist when towing a trai ler. For in-
format ion on cleaning,

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im ring * or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble
them ¢_&. .
..&, WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 35 7, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
.,. Use winter tires on all four wheels .
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
¢ _&. .An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.

The effectiveness of winter tires is reduced great­
ly when th e tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
'
..&, WARNING
- Never drive faster than the maximum per ­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice.
{® For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
-
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
.,.

CXl CXl .... N ,.__
N .... 0 N > 00
Check with an authorized Audi dealer or author ­
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains . They must not add
more than 0.53 inch (13 .5 mm) in height, includ­
ing the chain lock.
You must remove the snow chains on roads with­
out snow. Otherw ise, you could impair driving
ability and damage the tires.
~ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent.
0 Note
Snow chains can damage the rims/wheel cov­
ers * if the chains come into direct contact
w ith them. Remove the wheel covers * first.
Use coated snow chains.

When using snow cha ins, it may be useful to
sw itch on sport mode

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires. These t ires have been thoroughly tested
and been selected specifically for you r model for
their superb performance, road feel and handling
under a va riety of driving conditions. As k your au­
thorized Audi dealer for mo re de tails.
The low aspect ratio of these tires is indicated by
a numera l of
55 or less in the tire's size designa­
tion . The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more .
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
Wheels
be checked at least once a month and always
before a long trip
¢ page 336 .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi ­
ly by impact w ith potholes, curbs, gullies or
ridges on the road, particularly if the tire is un­
der inflated.
In order to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
t ions:
-Always maintain recommended inflation pres­
sures . Check your tire pressure every
2,000 miles (3,000 km) and add air if necessa­
ry.
-Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
-After any impact, immediate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
-Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not a lways
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire fa ilure.
If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
-These tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handlin g, they may ride less
comfortably and make more noise than other
choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
c ir cumstances, you should equip your vehicle
