[I) Tips
S ide assist does not measure actua l lane width. The system assumes
a fixe d lane w idt h. Detect ion in the le ft and right lanes is based on
this assumed lane width. When driving on narrow roads or whe n
dr iving to the left o r right o f the center of a travel lane, it is possi ble
tha t vehicles will be detected that are
not in the lane next to the lane

Operation
Side assis t comp ares the di stance and differen ce i n s peed of dete cted
vehicles with the speed of your vehicle. Whenever the difference in
speed and dis tance is registe red as not able if you were to c hange
lanes, a signa l light appears on the respect ive m irror .
Th e signa l can light up if you are passed by a vehicle or if you are
passing ano ther veh icle.
If you pass anot her vehicle slow ly (difference in speed less than 9
m ph, or 15 km/h), the signal ligh t w ill c ome o n as soo n as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference i n spee d is greater, the signal light w ill not come on .•
A ppli es to ve h icles : w it h sid e ass ist
Informational and alert stage signals
Side ass ist has two signa l stages:
• the informational stage signa l, and
• the alert stage signal.
Side assist helps you by using the appropr iate signa l stage,
depending on w het her o r no t you have activated the turn signal, and
thus have indicated that you are or are not changing lanes.
Informational stage signal
As long as you have not activated the turn signa l, s ide assist informs
you of detected vehicles that a re reg istered as be ing in a no table loca
tion if you we re to change lanes. Whenever the detected vehicle's
differen ce i n spee d and dis tance is registe red by s ide ass ist as
notable, the signal light on the respective mir ror produces muted
ill umin ation.
T he br ightness of the i nfo rmat iona l stage sig na l is desig ned not to be
as intense, so t hat it does not inte rfe re with yo ur v iew of the road
w hen you are d rivi ng and have no intention of chang ing lanes . When .,,,

MMI settings
The basic brightness setting of the signal on the outside
mirror can be adjusted via the MMI.
-Select: Function button ( CAR j > Systems * > Audi side
assist .
The brightness of the signal l ight for both the info rmationa l and alert
stages is automatically adjusted to ambient light conditions . In addi
tion , you can adjust the
basic brightness separate ly, via the bright
ness function.
Whi le mak ing the adjustment, the new brightness setting is
displayed briefly . The br ightness d isplayed is that of the informa
tional stage signal. The alert stage signal br ightness is linked to the
info rmational stage signal brightness.
The informational stage signal brightness should be adjusted so that
you notice the signal illumination when you look in the outside
mirror, but not when you look forward through the windshield.
In very dark or light surroundings, the automatic brightness setting
adjusts signal light brightness to maximum or minimum intensity, as
needed. In circumstances such as these, you may not notice any
change in the brightness on the outside mirror when adjusting the
basic brightness.
You may not notice the change until lighting conditions are normal
again.
W Tips
• Side assist is not active when the basic br ightness is adjusted. The
signal light comes on brief ly to help you make the adjustment.
• Your settings are automatically stored and ass igned to the remote
control key being used. •

General information
Side ass ist has limits and cannot detect vehicles under all road and
weather conditions . Please remember system limitations and never
rely on the system, especially when:
• driving through curves~
page 158,
• lanes a re of different width s~ page 159 . •
Ap plies to vehicles: w ith side ass ist
When driving through curves
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 poss ible that side assist may
registe r a vehicle two lanes over, and the signal on the outside mir ror
will light up.•

Lane width
Fig. 157 Lanes of a
normal width are
in
detection area
Fig. 158 Narrow
lanes: Side assist may
detect vehicles two
lanes away
Side assist's detection area is designed to cover lanes of standard
width to the left and right of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes - especially if you tend to drive on the edge of your
lane => fig . 158. Under these conditions, vehicles can also be
detected that are two lanes away, and side assist then could switch
between the informational and warning stage signals.
When driving in very wide lanes, vehicles in the adjacent lane may not
be detected because they are not inside the detection area .•

Wheel bolts
Wheel bolts must al ways be tightened to the correct
torque .
The design of wheel bolts is matched to the factory installed rims. If
different r ims a re fitted, the cor rect wheel bolts with the r ig ht leng th
and correctly shaped bolt heads must be used. Th is ensures that
w heels are fitted secure ly and that t he br ake system func tion s
correctly .
In certain circ umstances, you may not use whee l bolts from a
different veh icle -even if it is the same model~
page 368.
&_ WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control , a c ollision and seriou s personal
injury .
• Always keep the wheel bol ts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly t ighten ed .
• Never gr ease or oil the wheel bolt s and the threads in the wh eel
hubs. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle .
• Alway s maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a whee l los s. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The spe cifie d torq ue for the whee l bolts is 120 ft lb (160 Nm) wi th a
tolerance of ± 7,4 ft lb( ± 10 Nm). Torque whee l bolts diagona lly. After changing a wheel, the torq
ue m ust be checked as soo n as
possible wi th a t orqu e w rench -prefer ably by an auth o riz ed Audi

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
h ave bee n thorou ghly teste d and been se lec ted spe cifically fo r yo ur
model for their superb performance, road feel and hand ling u nder a
var iety of dr iving con ditions . Ask your authorized A udi dea le r for
more deta ils.
The low aspect ratio of these t ires is ind icated by a n umera l of
55 or
le ss
in t he tire 's s ize designation . T he numera l rep resents the ratio o f
the tire's sidewall he ight in relat ion to its tread width exp ressed in
pe rcen tage . Co nven tional ti res have a heig ht/w idth r atio o f 60 o r
more.
The performance of low-aspect-ratio tires i s particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pre ssure is regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always before a
long trip~
page 320, "Che cking t ire press ure".
What you can do to avoid tire and rim damage
Low aspe ct ratio tires ca n be damaged more eas ily by imp act wi th
potholes, curbs, gul lies or ridges on the road, part icu lar ly if the tire is
unde rinfl ated.
I n order to minimize the occu rrence of impact damage to the tires of
your vehicle, we recommend that yo u observe the follow ing p recau
tions:
• Always ma inta in recommen ded inflation p ressures. Check your
t ire press ure every 2,000 m iles (3,00 0 km) a nd a dd air i f ne cess ary.
• Drive ca ref ully on roads with potho les, dee p gullies or ridges. The
i m pact from d riving t hrough or over such obsta cles can damage you r
tires. Impact w it h a c urb may also cause damage to your tires . .,_
