8,_ WARNING , -
-Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, 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.
Wheels
-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
Fig. 191 Tire profile: treadwear indica­
tor
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. ..

plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gross A xle Weight Rating
("GAWR") is the maximum load
that can be appl ied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
c le Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a tra iler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

_& WAR NING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal in jury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating .

Care and cleaning
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . This in­
creases the risk of an acc ident. The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If yo u wash the ve hicle in an automatic car
wash, yo u m ust retract the rear spoiler if
necessary, and fold the exte rior mi rrors in
to reduce the risk of da mage. Power fo ld ing
ex ter ior mirro rs* m ust only be folded in and
out using the power folding func tion.
-
- To red uce the risk of pa int damage, do not
wash the vehicle in direct sun light .
- T o reduce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges o r similar items .
- Matte finish painted vehicle components:
-To reduce the risk of damage to the sur-
face, do not use polis hing agents or hard
wax .
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facili ties spec ially de­
s igned for that pu rpose . This will reduce the
r isk of dirty wate r contam inated with o il from
ente ring the sewe r system.

A WARNING
Improper use of the vehicle jack can cause se­
rious personal injuries.

tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if you
use the hex head, potentially causing an ac­
cident.
- The factory-supplied jack is intended only
for your vehicle model. Under no circum­ stances should it be used to lift heavy
veh icles or other loads; you risk injuring
yourself.
- Never start the engine when the veh icle is
raised, which could cause an accident.
- Support the vehicle securely with a ppropri­
ate stands if work is to be performed under­
neath the vehicle; otherwise, there is a po­
tential risk for injury .
- Never use the jack supplied with your Aud i
on another vehicle, particularly on a heavier
