2016 AUDI S6 traction control

Automatic transmission
Automatic transmission S tronic, tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty
driving style
characterized by quick accelerator
pedal movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed.
If desired , th e driver can also select the gears
manually (tiptronic mode) 9 page 110.
Various automatic transmissions may be instal­
led, depending on the model:
S tronic transmission
The S tronic is a dual-clutch transmission. Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In the tiptronic transmission, power is transfer­
red by a torque converter.

Selector lever positions
Fig. 115 Display in the instrument cluster: selector lever
position
The selector lever position engaged appears next
to the selector lever as well as in the instrument
cluster display.
P -Park
In this selector lever position the transmission is
mechanically locked. Engage P only when the ve­
hicle is
completely stopped¢&. in Driving the
automatic transmission on page 108.
To shift in or out of position P, you must first
press and hold the brake pedal and then press
the release button in the selector lever handle
while moving the selector lever to or from P. You
can shift out of this position only with the igni­
tion on.
R -Reverse
Select R only when the vehicle is at a full stop
and the engine is running at idle speed¢&. in
Driving the automatic transmission on
page 108.
Before you move the selector lever to R, press
both the button in the handle of the selector lev­
er
and the brake pedal at the same time.
When the ignition is on, the backup lights illumi­
nate when the selector lever is moved into R.
N -Neutral
The transmission is in neutral in this position.
Shift to this position for standing with the brakes

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road ho ld ing and vehicle
dynamics to help reduce the probability of skid­
d ing and loss of vehicle control. It works only
when the engine is runn ing . E SC detects certain
d ifficult dr iving sit uat ions, including when t he
ve hicl e is begin ning to spin (yaw) out of contro l
and helps you to ge t the veh icle back under con­
tro l by se lective ly braking the wheels, and/or re ­
ducing engine powe r and provid ing steering as­
sistance to help hold the vehicle on the dr iver's
intended course. The indicator light
GJ in the in­
strument cluster blinks when ESC is taking action
to help you co ntrol the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not a lways be able to help out under all con­
d itions you may come up aga inst. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coeff icient of friction of the road surface. When
there is a section of dry road that is sudde nly cov­
e red with water, slush o r snow, ESC cannot pe r­
form the same way it wo uld on the dry s urface . If
the vehicle hydrop lanes (rides on a cushion of wa­
ter i nstead of the road su rface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been interrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, pa rticula rly on w inding roads, ESC
cannot always deal as effect ively w it h difficult
d riving si tuations tha n at lowe r speeds.
Always adjust your speed and driving style to road , traffic and weather cond itions . ESC cannot
override the vehicle's physical lim its, increase the
ava ilab le traction, o r keep a ve hicle on the road if
road departure is a resu lt of driver in attention .
I nstead, ESC imp roves the possibi lity of keep ing
Intellig ent Technology
the vehicle under contro l and on the road d uring
extreme mane uvers by using the driver's steering
i nputs to help keep the vehicle go ing in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can provide any assistance, you may not exper i­
ence the benefits of ESC.
ESC is switched on all the time. In certain s itua­
tions when you need less tract ion, you can sw itch
off ASR by press ing the button
lm c> page 188,
fig . 177 . Be sure to switc h ASR on again whe n
you no longer need less traction.
The following systems are integrated in the ESC:
Anti-lock braking sy stem (ABS )
ABS prevents the wheels from locking when brak ­
ing. The vehicle can still be steered even dur ing
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stab ilize the veh icle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the dr iver
presses the brake peda l quickly in emergency sit­
uat ions. You must press and ho ld the brake pedal
unt il the dange rous situation is over . In vehicles
with adaptive c ruise cont rol*, the b rake ass ist
system is more se nsitive if the distance detected
to the ve hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR reduces engine power whe n the dr ive wheels
begin spin ning and adapts the force to the road
co ndit ions. This makes it eas ier to s tart, acce ler­
ate a nd d rive up incl ines.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other dr ive
wheel or wheels if the vehicle is equ ipped with all
whee l drive*) . This function is not available a t
highe r speeds .
In extreme cases, EDL automat ica lly switches off
to keep t he brake o n the braked wheel from over­
hea ting . T he veh icle is still working co rrectly. EDL

Wheels
- These tires may wear more q uickly than othe rs.
- Please also remembe r th at, w hile these tires
deliver responsive handling, they may r ide less
comfortably and make more noise than ot her
cho ices.
Reduced performance in wint er/ cold season
condit ion s
All tires are designed for certain purposes. The low aspect ratio, ultra high pe rformance tires
or iginally insta lled on yo ur vehicle are intended
for maximum d ry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weathe r cond itions .
If you drive under those
circumstances, you should equ ip your ve hicle
with all-season or winter tires, wh ich offe r bette r
traction under those condit ions. We sugges t you
use the recommended snow or all-season tires
specified for yo ur vehicle, or their eq uivalen t.

Uniform tire quality grading
- Tread we ar
- Tra ction AA A B C
- Temperature ABC
Qua lity grades can be found where app licab le on
the t ire side wall betwee n tread s hou lder and
maximum sect io n w idth ¢
page 231, fig . 193.
For e xample: Tread wear 200 , T raction AA, Tern·
pe rature A.
All passenger car tires must conform to Federa l
Safety Requirements in addition to these grades .
Tread wear
T he
tread wear grade is a compara tive ra ting
b a se d on the wea r rate of the t ire when tes ted
under contro lled conditions on a specified gov ·
ernment test co urse.
F or examp le, a tir e graded 150 would wear one
a nd one ha lf ( 11/2) times as well on t he gove rn·
men t course as a tire graded 100 .
T he rela tive perfo rmance of t ires depends upon
the a ct u a l c ondi tions of their use, howeve r, and
may depart s ignific ant ly from the norm d ue to
248
variations in driving habits, service p ract ices an d
differences in road characteristics and climate.
Traction
The
traction grades , from hig hest to lowest , a re
AA , A, B and
C. Those grades rep resent the tire's
a bility to stop o n wet p avement as measure d un­
der controlled conditions on specified govern ·
ment test s urfaces of asphalt an d concrete. A tire
marked C may have poor traction perfo rmance
¢ ,& .
Temperature
The
temp eratur e grades are A ( the highest), B,
and C, representing the tire 's resistance to the
generatio n of heat and its ability to dissipate
heat when tested under contro lled 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 s udden
tire failure¢ ,&.
The grade C cor responds to a level of perform ·
ance which all passenger car tires must meet un·
der the Federal Motor Vehicle Safety Standard
No . 109 . Grades Band A represent hig her levels
of performance on the laboratory test wheel than
t h e m inim um requ ired by law .
A WARNING
-
The tract io n grade assigned to this t ire is
based on st raig ht-a head braking tr action
