The detection~ page 139, fig. 135 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle , and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes
are
not covered by the radar sensors .
rn Tips
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
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~

Applie s to vehic les: w ith s ide a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes , a signa l light appears on the respective mirror .
The signal can light up if you are passed by a vehicle or if you are
passing another vehicle .
If you pass another vehicle slowly (difference in speed less than 9
mph, or 15 km/h), the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist. When the
difference in speed is greater, the signal light will not come on. •
Appli es to vehicles : with si de assist
Informational and alert stage signals
Side ass ist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropr iate signal stage,
depending on whether or not 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 signal, s ide assist informs
you of detected vehicles that are reg istered as being in a notable loca
tion if you were to change lanes . Whenever the detected vehicle's
difference in speed and distance is registered by side assist as
notable , the signal light on the respective mirror produces muted
illumination.
Th e brightness of the informat ional stage signal is designed not to be
as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. When
you look in the outs ide mirror, you can clearly see the informational
stage signal.
Alert stage signal
When you act ivate the turn s ignal , and side assist has detected a
vehicle in a notable location on that particular side , the signal light on
this side mirror flashes brightly. The repeated brief and bright
flashing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so that
you can safely complete the lane change~
& in "Safety tips" on
page 145.
rn Tips
The brightness of the signa l light on the outside mirrors can be
adjusted with the MMI*

(I) Tips
• Side assist is not act ive when the basic br ightness is adj usted. The
signal light comes on briefly to he lp you make the adjustment .
• Your settings are automatically stored and assigned to the remote

General information
Side assist has limits and cannot detect vehicles under all road and
weathe r conditions . Please remember system limitat ions and never
re ly on t he system, espec ially w hen:
• driving t hrough curves =>

• lanes a re of differe nt widths => page 144. •
Ap plies to veh icles : w it h side ass ist
When driving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 3 28 feet (1 00 m).
When driving through a cu rve, it is possible that side assist may

holding and safe handling when in good condition and properly
inflated
=> & .
We recommend that all work on t ires and wheels be performed by an
authori zed Au di deale r. They are fam il ia r with recommended proce
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the o ld tires.
Authorized Aud i dea lers have the necessary info rmation about tech
nical requirements for insta lling or changing tires and rims .
Replacing tires and wheels
Tires should be replaced at least in pa irs and not ind iv idually (for
example both front tires or both rea r tires together) .
Be sure to read and heed the in formation to the tire pressure mon i
t o ring system *=>
page 310.

page 295, fig. 213) l ists the specifications of the
orig inal equipment tires installed on your vehicle at the time it was
manufactured.
Federal law requires tire manufacturers to place standardized infor
mation on the sidewall of all tires =>
page 303, fig. 216. This infor
mation identifies and descr ibes the fundamental characteristics, the
quality grade of the tire and also provides a tire identification number
for safety standard cert ification and in case of a reca ll.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires. Radia l tires have the tire specifications marked on the sidewall,
for examp le:
P255 / 35 Rl9 96V XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
255 Nominal tire width in mm of the tire from sidewall edge to side -
wall edge . In general, the larger the number, the wider the tire
35 Height/w idth ratio in percent (aspect ratio)
R Tire construction: Radial
19 Rim diameter code (in inches)
96 Load rating code
Y Speed rating letter code
XL (or "xl", "E XTRA LOAD", or "RF" Indicates that the tire is a"Rein
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the tire has some mud and snow capa
bility The tires could a
lso have the information of direction of rotation
=>
page 291 .
Tire manufacturing date
The manufacturing date is also indicated on the tire sidewall
(poss ibly only on the
inner side of the wheel):
"DO T ... 2209 ... "means, for example, that the tire was produced in
the 22nd week of 2009.
Speed rating (letter code)
The speed rating letter code on the wheels ind icates the maximum
permissible road speeds =>

& WARNING (conti nu ed )
• If you install wheel trim disc s on the vehicle wheels , make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to ove rhe at, increasing stopping distances
and cau sing a collision .
0 Note
• For tech nical reasons, it is not ge ne rally poss ib le to use the wheel
r ims from other vehicles. This can hold true for whee ls of the same
veh icle type.
• If the spare tire is different from the t ires that you have mounted
on yo ur veh icle (for examp le w inte r tir es or wide profile tires), then
use the spare tire for a short per iod of t ime on ly and drive with extra
c are . Replace the fla t ti re wi th t he tire matc hing the o thers on you r
vehicle as soon as possible .
• If you should put differen t wheel s and tires o n yo ur vehicle (e.g.
w inter whee ls and t ires), you must be certa in that the wheels and
ti res are comp atib le with the t ire pressure mon ito ring system*.
Otherwise the system will register a malfu nction and a fau lt message
w ill be displ ayed. Fo r more informa tion, conta ct your au thori zed Au di

All passenge r car ti res mus t confo rm to Fe d er al Safety Requireme nts
in addition to these grades.
Tread wear
T he tread wear grade is a comparative rating based on the wear rate
of the t ire whe n tes ted under cont rolle d conditions on a specifie d
government test co urse.
F or example, a tire graded 150 would wear one a nd one hal f (1 1/2)
t imes as well on t he government course as a tire graded 100 .
The relat ive performance o f tires depen ds upon the act ua l conditions
of their use, however, and may de pa rt sign ifican tly from the no rm
due to variat ions in dr iv ing hab its, se rvice practices and differences in
ro ad characte ris tic s and climat e.
Traction
Th e traction grades, from high est to lowest, ar e AA, A, Band C. Those
grades represent the tire's ability to stop on wet pavement as
me asu red under con trolled conditions on spe cifie d gove rnme nt te st
surfaces of asphalt and conc rete . A tire marked C may have poo r trac
