ALL wheel drive
(quattro)
Appl ies to vehicles: wit h all whee l drive
In all wheel drive, all four wheels are pow ­
ered .
General information
In all wheel drive, the driving power is divided
between all four wheels. This happens auto­
mat ica lly depending on you r driv ing behavior
as we ll as the current road conditions. Re fer
to
¢ page 185, Electronic stabilization con ­
trol (ESC) .
The all wheel drive concept is designed for
h igh engine power . Yo ur vehicle is exception­
a lly powerful and has excellent driving charac ­
teristics bot h under normal driving conditions
and on snow and ice . A lways read and fo llow
safety precautions
c> & .
Wint er t ire s
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
conditions . However, in winter we recommend
using winter or all season t ires on
all four
wheels, because this will improve the braking
effec t.
Snow cha in s
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive
c> page 241, Snow chains.
Replacing tire s
For vehicles with a ll wheel d rive, only wheels
with the same ro lling circumference should be
u sed. Avoid wheels with different tread
depths ¢
page 236 .
Offroad vehicle?
You r A udi is not a n offroad vehicle -there is
not enoug h ground clearance. For this reason ,
avoid difficu lt terrain. Refer to
c::> page 266.
A WARNING ~
- Also, in vehicles with a ll w heel drive,
adapt your driving sty le to the c urrent
road and traffic cond itions. Do not let
the increased safety provided tempt you into taking risks .
- The braking ability of your veh icle is lim­
ited to the traction of the wheels. In this
way, it is not different from a two wheel d rive vehicle . Do not be tempted to ac­
celerate to a high speed when the road is
slippe ry this inc reases the r is k of an acci­
dent.
- Note that o n wet s treets, the front
wheels ca n "hydrop lane " if driv ing at
speeds that are too high. Unlik e fron t
wheel drive vehicles, the engine does not rev higher sudden ly when the vehicle be­
g ins hydroplaning. For this reason, pay
attention to the road conditions regard­ less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventiona l energy
system is not d riven for a long time , the bat­
te ry is drained by equ ipment ( for example the
immobilizer) . In certain c ircumstances, there
cou ld may not be enough energy to start the
engine .
1J1-

This will help ensure that vehicle function,
performance and safety are not impaired
c::> _& .
Attempting to wo rk on electronic components
and the softwa re used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved . Th is means that you risk both
a substantial reduction in the operat ional
safety of you r vehicle and an increased wear of
ve hicle parts
c::> ,& .
Author ized Audi dealers w ill perform this
work in a profess ional and competent manner
or, in special cases, refer you to a professional
company that specializes in such mod ifica­
tions.
A WARNING
Imprope r repairs and modifications can
change the way vehicle systems work and
cause damage to the veh icle and ser ious
personal in jury.
(D Note
-
If emergency repairs must be performed
elsewhere, have the ve hicle examined by
an authorized A udi dealer as soon as possi­
ble.
