Selective catalytic
reduction (AdBlue)
General information
Applies to vehicles: with diesel engine
In vehicles with selective cata lytic reduction, a
urea solution (AdB lue) is injected into the ex
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
Ad B lue is the marketing name for Diesel Exha ust
Fl uid (DEF).
The AdBl ue is carried in a separate ta nk in the ve
hicle. The Ad Blue usage accounts for approxi
mate ly 0.5% to 1.2% of the diesel f uel that is
used .
W hen a message about refilling the Ad B lue ap
pears in the instrument cluster disp lay, you must
refill the Ad Blue you rself or have it refilled by an
author ized Audi dealer or authorized Audi Service
Facility ¢
page 235.
A WARNING
-
Failure to heed AdBlue refill informat ion in
the instrument cluster can prevent the vehicle
from being started and dr iven . If the vehicle
cannot be driven and an emergency arises,
perso na l in jur y can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry .
(D Tips
-The instrument cluster display indicates the
distance rema ining t hat can be driven
¢ page 234. If the AdBlue tank is com
plete ly empty, the engine wi ll not start
again after the ignition is sw itched off.
- Ad B lue is req uired by law to operate this ve
hicle.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au
thorized Audi Service Facility .
These facilities have the proper
knowledge and are equipped with
the required tools and replace
ment parts.
.,. New tires do not yet have the
optimum adhesion properties .
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,. Only use tires with the same de
sign, size (rolling circumference)
and as close to the same tread pattern as poss ible on all four
wheels .
260
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,. Audi recommends that you use
Audi Original equipment tires . If
you would like to use d ifferent
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina
t ion that is different from what
was installed at the factory, con
sult with an authorized Audi dealer or authorized Audi Service
F acility before making a pur
chase ¢&, .
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.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so tha t the
drive system is not damaged by .,.
different tire speeds. For this reason, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ 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.
Tires and wheels
-Only use tires that are more
than 6 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 allow enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

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. ..

- Keep the tire sealant away from children .
- In vehicles with a tire pressure monitoring
system*, using tire sealant can results in an
incorrect display or a system malfunct ion.
Drive carefully to the nearest author ized

ty.
@ Tips
- If sealant leaks, allow it to dry in place. You
can then pee l it off like a sticker.

I.
.,. Inflate the tire to between 29 psi (200 kPA)
and 36 psi (250 kPA) and read the pressure on
the gauge .
.,. If this tire pressure is not reached, drive your
veh icle approximately 33
ft (10 meters) for
ward or backward so that the sealant can be re
distr ibuted inside the tire.
_& WARNING
-Read and follow the manufacturer's safety
precaut ions on the compressor and in the
instructions on the bottle of sealant.
- If a tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not
continue driving.
- If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au
thorized Audi Service Facility for assistance.
(D Tips
Do not operate the compressor for more than
6 minutes continuously, or it can over heat.
Once the compressor has cooled, you can con
