Driver assistance

Side assist
Description
Applies to: vehicles with side assist

e|


Fig. 120 Diagram: driving situations and displays in the ex-
terior mirror (example)
General information
Side assist monitors the blind spot and traffic in
the adjacent lanes behind the vehicle. Within sys-
tem limits, side assist can detect traffic that is
approaching from behind and provide a warning
when you are changing lanes and turning. The
system uses the data from the radar sensors at
the rear corners of the vehicle.
The side assist is active at walking speeds and
higher. If an object that is classified as critical is
approaching, the display in the exterior mirror @)
on the corresponding side of the vehicle will light
up.
Driving situations
The system can provide warnings about the fol-
lowing risks:
@ Approaching vehicles: a vehicle may be clas-
sified as critical in some cases, even if it is
farther away. The faster a vehicle ap-
proaches, the sooner the display will turn on.
154
@ Vehicles traveling in the same direction: the
display will turn on if vehicles traveling in the
same direction as your vehicle are classified
as critical. The side assist warns you of all de-
tected vehicles when they are in the “blind
spot” or before they reach that point.
@® Vehicles you are passing: the display only
turns on if you slowly pass a detected vehicle
(difference in speed between the two vehicles
is less than 9 mph (15 km/h)). There is no
display if you pass a vehicle more quickly.
Information stage
At the information level, the side assist informs
you of detected objects that are classified as criti-
cal. This is even possible when your vehicle is sta-
tionary and the turn signal is turned on, so that
the system can also assist you when turning.
From speeds of approximately 6 mph (10 km/h)
and higher, the system will warn you of detected
objects that are classified as critical, even if the
turn signal is not turned on.
The display remains dim in the information stage
so that you are not distracted while looking for-
ward.
Warning stage
If you activate a turn signal and the display flash-
es brightly, side assist is warning about objects
that have been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 147,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle lo-
cated in the area that is critical for a lane change.
For example:

— 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.

Loose wheel warning
Applies to: vehicles with loose wheel warning
Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the fi indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.
Messages
fl Wheel bolts loose. Please safely stop the ve-
hicle and check all wheel bolts!
Loose wheel warning for at least one wheel > A\.
Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 274, Finishing.
fl Wheel assessment active. Please continue
driving carefully
After this message appears and you have checked
the wheel bolts, the assessment phase begins
when the vehicle is in motion. This may take sev-
eral minutes.
fl Loose wheel warning: malfunction! See
owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.
258
Z\ WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
— If a message appears, reduce your speed im-
mediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible
and check the wheel bolts.
— Check your wheels for damage. Have the
damaged wheels checked and/or replaced
immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that
the wheels are attached correctly.
G) Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.
— Using snow chains may result in a system
malfunction.
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 traction
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 > A\ in
General information on page 243. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.

Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 244, fig. 162.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
>A.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure > A.
260
The grade C corresponds to a Level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.

Z\ WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics.


ZA\ WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.

ZA WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and >
