Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions . However, in winter we recommend using
winter or all season tires on all four wheels, be­
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 227, Snow chains.
Replacing tires
For vehicles w ith all whee l dr ive, only whee ls w ith
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 218, 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.
_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iving style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel dr ive 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 driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Intelligent Technology
Rear spoiler
The extendable rear spoiler increases driving sta­
bility.
Fig. 141 Center console: button for the rear spoiler
T he rear spo iler retracts and extends. Var ious op­
erating modes (automatic o r manua l mode) can
be activated .
Automatic mode (normal operation)
-Extends automatically: when the vehicle speed
exceeds approx imately 80 mph (130 km/h) .
- Retracts automat ically: when the vehicle speed
drops below approx imately SO mph (80 km/h).
Manual mode
- Extending manually: briefly tap the button to
fully extend the rear spoiler.
- Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
When at speeds between 10 mph (20 km/h)
and 80 mph (130 km/h), the rear spoiler will
completely retract when you tap the button.
Indicator lights
lfa /. Rear spoiler: System fault!
The rear spoiler may not have extended due to a
malfunction . This cou ld change the vehicle 's driv­
ing characteristics at high speeds. Do not drive
faster than 85 mph (140 km/h) . Drive to an au­
thorized Audi dealer or authorized Audi Service Facility immed iately to have the malfunction cor ­
rected . The color of the indicator light depends
on the vehicle speed .

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

manufacture date
The manufacture date is listed on
the tire sidewall (it may only ap­
pear on the inner side of the tire):
DOT ... 2216 ...
means, for example, that the tire
was produced in the 22nd week of
the year 2016.
@ Audi Original Tires
Audi Original equipment tires
with the designation "AO" have
been specially matched to your
Audi. When used correctly, these
tires meet the highest standards
for safety and handling. An au­
thorized Audi dealer or author­
ized Audi Service Facility will be
