2018 AUDI S4 wheel alignment

Wheels
&,. WARNING
-Do not use steel rims that are 17 inches or larger . Other­
wise, damage to the vehicle
and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size . If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so .
-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.

-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear /damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
- Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear .
-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
..

could slip and cause an injury if it does not
have sufficient hold on the vehicle.
- To reduce the risk of an accident, never start
the engine when the vehicle is raised.
- To reduce the risk of injury, support the ve­
hicle securely with suitable stands if work is
to be performed underneath the vehicle.
- To help prevent injury to yourself and your
passengers:
- Do not raise the vehicle until you are sure the jack* is securely engaged.
- Passengers must not remain in the vehicle when it is jacked up.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- Make sure jack position is correct, adjust as necessary and then continue to raise
the jack*.
- If work has to be done under the vehicle, ensure that it is safely supported on suita­
ble stands
-risk of injury!
- Never start the engine when the vehicle is on the jack*
-risk of accident!
(D Note
Do not lift the vehicle by the sill. Position the
vehicle jack* only at the designated mounting points on the side sill. Otherwise, your vehicle
will be damaged.
