2018 AUDI A3 SEDAN traction control

Intelligent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In oil wheel drive, oil four wheels ore powered.
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
ly depending on your driving behavior as well as
the current road conditions. Also see
c:> page 148, Electronic Stabilization Control
(ESC) .
The a ll wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c:> & .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, using winter or all season tires
on
oil four wheels in the winter is recommended,
because this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 346, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference shou ld be used.
Avoid using tires with different tread depths
c:> page 33 7, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your driv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
152
because this increases the risk of an acci ­
dent.
- The braking ability of your vehicle is limited
to the traction of the whee ls. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driv ing at speeds that
are too high . Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydrop laning .
Fo r this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
Your vehicle is equipped with an intelligent ener ­
gy management system for distributing electrici­
ty. Thi s significantly improves the starting ability
and increases the vehicle battery life.
(D Tips
-If you drive short distances frequently, the
vehicle battery may not charge enough
whi le driving. As a result, convenience func­
t ions for electrical equipment may be tem­
porarily unavailable.
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iods of
t ime, or if electrical equipmen t is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.

A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
@ Note
Snow chains can damage the rims/wheel cov­
ers* if the chains come into direct contact
with them. Remove the wheel covers* first .
Use coated snow chains.
(D Tips
When using snow chains, it may be useful to
switch on sport mode

Low-profile tires
App lies to: ve hicles with low -profi le tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
la rger r im diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
L ow -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole
covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire
pressure¢ page 341.
To reduce the risk of damage to the tires and rims, drive very carefully on poor roads.
Check your wheels regularly
every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility .
L ow -profile tires can wear out faster than stand­
ard tires.
Wheels
Uniform tire quality grading
- Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width
¢ page 331, fig. 275.
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 cond it ion s 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 driv ing habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA , A, Band
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
¢,& .
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 ¢,& .
