Wheels
differently even if they are the
same size
c::> .,&..
~ If you would like to equip your
vehicle with a tire/rim combina­ tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
c::> ,& .
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­ porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire that has the same circumference as
the regular tires.
174
A 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.
-Do not use run-flat tires on
your vehicle. Using them when ...

Wheels
on the front axle and vice versa.
This will allow the tires to have approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­ ing to the running direction indi­
cated on the tire sidewall
¢ page 196.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
s ide, drive slowly and carefully to
the nearest authorized Aud i deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect ­
ed.
A WARNING
Tread that has worn too low or
different tread depths on the
t ires can reduce driving safety.
This can increase the risk of an
accident because it has a nega­
t ive effect on handling, driving
through curves, and braking, and because it increases the
176
risk of hydroplaning when driv­
ing through deep puddles.

Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.

A WARNING 1 = -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak tract ion charac­
teristics.
A WARNING
The temperature grade for this t ire is estab­
lished for a t ire that is properly inflated and
no t overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(!) General notes
Applies to: veh icles with tire pressure monitoring system
-
Each tire, including the spare (if provided),
should be checked monthly when co ld and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placa rd or
tire i nflat ion pressure label. (If your vehicle has
tires of a different s ize tha n the s ize indicated on
the veh icle placard or tire inflation pressure la­
be l, yo u sh ou ld de termine the prope r tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a tire pressu re monito ring sys tem
(TPMS) that ill uminates a low tire p ress ure te ll­
tale when one or more of your tires is significan t­
l y under-inflated. Accordingly, when the low tire
p ressure tellta le illuminates, you should stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi­
cantly under-i nflated tire causes the tire to over­
h eat and can lead to t ire failure . Unde r-inflation
a lso reduces fuel efficiency and t ire t read life,
Wh eel s
and may affect the vehicle 's handling an d stop ­
ping ability.
Please note tha t the TPM S is not a s ubstitute fo r
prope r ti re maintenance, a nd it is the dr iver's re­
spons ibility to maintain co rrect t ire pressure,
even if under-inflatio n has not reached the level
to t rigge r ill umination of the TPMS low t ire pres­
s ur e te lltale .
Yo ur vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TP MS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfu nction, the telltale w ill flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated . Thi s seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation o f replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lf u nction te lltale after replac ing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lt ernate tires and
wheels allow the TPMS to continue to function prope rly.

Emergency assistance
& WARNING
You or your passengers could be injured while changing a wheel if you do not follow these
safety precautions :
- If you have a flat ti re, move a safe d ista nee
off the road . Turn off the engine, turn the
emergency flashers on and use other warn·
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed with the
folding chocks or other objects. When one
front wheel is lifted off the ground, placing
the Automatic Transmission in "P" (Park)
will
not prevent the vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack .
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
c:> page 102 .
(D Tips
Obey all laws.
