Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted .
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive*.
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­ i zed Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
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
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first . Use coated snow chains.
Wheels
- Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged .
(D Tips
When using snow chains, it may be useful to
switch on sport mode
c> page 121.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim 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.
Low-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
c>page 215.
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.
Low-profile tires can wear out faster than stand­
ard tires.
Uniform tire quality grading
-Tread wear

Emergency assistance
-If the tire is too severely damaged, see an
authorized Aud i dealer or authorized Aud i
Service Facility for assistance.
@ For the sake of the environment
You can give the used tire sealant bottle to an
authorized Audi dealer or authorized Audi
Serv ice Facility for disposal.
(D Tips
Remember to obtain a new bottle of sealant
from an authorized Audi dealer or authorized
Audi Serv ice Facility after repairing a tire.
Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel.

before you stop ¢.&, .
.,. All passengers sho uld leave the car and move
to a safe location (for instance, be hind t he
guardrail) ¢.&, .

ing devices to alert other motorists .
- Make sur e that passengers wait in a safe
place away from the vehicle and we ll away
from the road and traffic.
236
- To help prevent the vehicle from moving
suddenly and possibly s lipping off the jack,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed. When
one front wheel is lifted off the ground,
p lacing the Automat ic Transmission in P

Before changing the wheel, you must activate
the jacking mode, so that the automatic con­
trols for the Adaptive Air Suspension* do not
make it more difficult to lift the vehicle with
the jack

(D Note
-Be aw are of the fo llow ing po ints b efor e lift­
ing the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmission housing, the front
or rear axle or the body side members.
This could lead to serious damage .
-To avoid damage to the underbody or
chassis frame, a rubber pad must be in­
serted between the floor jack and the lift
points .
.,.
251

Emergency situations
-Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
-Before driving over a workshop hoist, en­
sure that there is sufficient clearance be­
tween the hoist and low parts of the ve­ hicle.
Vehicle transport
Applies to: vehicles with air suspension
~ Note
When transporting the vehicle on a car carri­
er, train , ship or by other means, only tie the
vehicle down at the running surface of the
tires, which is the outer circumference. Secur­
ing the vehicle at the axle components, sus­
pension struts or towing eyes is not permitted
because the pressure in the air suspension
struts can change during transport. The vehi­
cle may not be secured sufficiently if this hap­
pens.
