Driving
with
your quattro®
With All Wheel Drive, all four wheels are driven.
General
information
With All Wheel Drive, power is distributed
to all fo ur whee ls. This
happens automatically
depending on you
r
driving style a nd the road
conditions at
the t
ime. See a lso
=>
page 189, "Electronic differential
lo
ck
(EDL)".
W inter
tires
W hen d riving in the winter, your vehicle with
All
Whee
l
Drive has an
advantage, even with reg ular t ires
.
In
winter road cond it ions
it
may
be advisab le to mou nt w inte
r
ti res (or all-se
a
so
n t
ires) for imp roved
dr iveability and braking:
these tires
must be mounted on
all four
wheel
s.

Replacing
wheels/tires
Veh icles with All Wheel Drive m ust always have t ires of the same s ize.
Also avoid tires with different tread depths. For details see page

page 257, "New tires and replac ing ti res
an
d wheels".
Off-Road
driving?
Your Audi does not have enough ground clearance
t
o be used as a
n
off-road vehicle.
It is
therefore best to
avoid rough
tracks
and
uneven
te
rr
ain as
much
as poss ible. Also refe
r
to=> page 199.

WARNING
Always adjust your driving to road and traffic conditions
.
Do not
let the extra safety afforded by the all-wheel drive tempt you into
taking extra risks.
•
Although the quattro ®all -wheel drive
is
very effective, always
remember that braking capacity is limited by t ire traction. You
should therefore not drive at excessive
speeds
on icy or slippery
road
surfaces.
•
On wet road surfa ces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (hydro-
planing
)
. If this should occur, you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
vehicle. Always dr ive at
speeds
which are adjusted to the road
conditions - risk of crash!

Energy management
Starting
ability
is optimized
Energy managemen
t
controls the distribution of elec
-
trical energy and thus optimizes the availability of elec-
trical ene rgy for s
ta
rting the
eng
ine.
If
a vehicle w ith a convent ional energy sys
t
em is not d riven fo
r
a long
period of time, t
he
battery is discha rged by idling cur rent consumers
(e .g. immob ilizer). In ce rtain circumstances
it can result
in t
here
being insufficient energy availab le to start the engine
.
