2017 AUDI A8 traction control

Intelligent Technology
The stee ring wheel will be easy to move after
starting the engine . Re-initialization might be
necessary if the steering whee l was moved hard
t o the lef t and right wh ile the vehicle was not
mov ing. The display turns off if the initialization
was successful.
(D Tips
- If the. or
1;:r- ij ind icator light only stays on
for a short time, you may continue driving.
- The dynamic steering stability systems
c> page 126 are not available in the event of
a system ma lfunction.
- For additional informat ion on dynamic
steering, refer to
c> page 110.
All wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In a ll wheel drive, the driving power is divided be­
tween a ll four wheels . T his happens automatical ­
ly depending on your driving behavior as well as
t he current road cond itions. Also see
c> page 126, Electronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear whee ls is variable and can be
ad ju sted using the dr ive select
c> page 110.
The all wheel drive concept is designed for h igh
eng ine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iv ing condit ions and on
snow a nd ice. Always read and fo llow safety pre­
cautions

Winter tires
By us ing all w heel d rive , yo ur vehicle has good
forward mot ion w ith standa rd t ires in winter con­
d itions . However, in winter we recommend us ing
w in ter o r all season t ires o n all fo ur wheels, be ­
cause this will improve the b raking effect .
Snow chains
If there are snow chai n laws, snow chains must
a lso be used on vehicles with all w heel d rive
c> page 298, Snow chains .
130 Replacing tires
Fo
r vehicles wi th a ll wheel d rive, o nly wheels with
the same ro ll ing circ umfe rence sho uld be used .
Avo id using tires with different tread depths
c> page 290, New tires or wheels .
Offroad vehicle?
You r A udi is not an off road vehicle -there is not
enough ground clearance. For th is reason, avoid
difficult terrain .
A WARNING
- Also, in ve hicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel d rive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is s lippery, be ­
c a use th is i ncreases the r is k of an accident.
- Note that on wet st reets, the front wheels
c a n " hydroplane " if driv ing at speed s tha t
are too high. Unlike front wheel drive
vehicles, t he engine does not rev higher sud ­
de nly when the vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is no t drive n for a long t ime, the veh icle bat­
te ry is drained by equ ipment (fo r example, the
i mmob ilizer). In certa in circ umstances, there
could may not be enough energy to start the en ­
gine.

A WARNING
To reduce the risk of an accident, only use
Audi connect services when road and traffic conditions permit.

Wheels
- Please a lso remember that, wh ile these tires
deliver responsive handling, they may ride less
comfortably and ma ke more noise than other
cho ices.
Reduc ed performance in winter /cold s eason
condit ions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance t ires
or iginally i nstalled on your vehicle are intended
for maximum dry and wet road performance and
handling . They are not s uitable for cold, snowy or
icy weathe r cond itions.
If you drive under those
circumstances, you s hou ld equ ip your ve hicle
with a ll-season or win ter tires, wh ic h offe r bette r
traction under those con dit ions . We suggest you
use the recommended snow or all -season tires
specified fo r your vehicle, or their equivalent.
Refer to¢
page 298 for more deta iled info rm a­
tion regarding w in ter tires.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperatu re ABC
Qua lity grades can be found where applicable on
the t ire side wall betwee n tread s hou lde r and
maximum sect io n w id th
¢pag e 283, fig. 265.
For e xample: Tread wear 2 00 , Traction AA , Tem­
perature
A .
All passenger car tires must conform to Federa l
Safety Requirements in addition to these grades.
Tread wea r
The tread wear grade is a comparat ive ra ting
based on the wear rate of the tire when tested
under contro lled conditions on a specified gov­
ernment test course.
F or examp le, a t ire graded
150 would wear one
and one ha lf
( 1 1/2) times as well on the govern ­
ment course as a tire g raded
100 .
The rela tive perfo rmance of tires depe nds upon
the actua l condi tions of their use, howeve r, and
may depart significant ly from the norm d ue to
300
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
ability 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 performance
¢ _& .
Temperature
The temperature 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 b raking tr action
tes ts, and do es not in clude acceler ation, cor­
nerin g, hyd roplaning or pe ak traction ch arac­
teristics.
A WARNING
T he temperat ure grade fo r thi s tire is esta b­
lishe d for a tire that is properly inflated and
not ove rloaded. Excessive speed, underinfla -
tion, o r excessive load ing, either separately or
in comb inat ion, can cause heat bu ildup and
-
possible tire failure. ..,.
