Selective catalytic
reduction (AdBlue/DEF)
General information
Appl ies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalyt ic reduction, a
u rea solution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
conve rter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or D EF (Diesel Ex­
haust Fluid) . Ad Blue is used in the follow ing .
The Ad Blue is carried in a separate tank in the ve­ hicle. The AdBlue usage acco unts for approxi ­
mately 0 .5% to 2 .5% of the diese l fuel that is
u sed .
When a message about refilling the AdBlue ap­ pears in the instrument cl uster display, you must
ref ill the Ad B lue yourself or have it refilled by an
autho rized Aud i dea le r o r a uthorized Audi Serv ice

Checking and Filling
& WARNING
AdBlue can irritate the skin, eyes and respira­tory system. If there is contact with the fluid,
flush immediately with plenty of water . Con­
sult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241 -1. Do not mix any addi ­
tives with the Ad Blue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank. There is a
risk of damaging the fuel tank system and
the engine. See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge . AdBlue residue that is
not removed will crystallize and can damage
the affected surface.
- Do not store refill bottles or canisters per ­
manently in the vehicle. If the container
leaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow AdBlue to come into contact
with clothing. If there is contact with the
fluid , flush immediately with plenty of
wa­
ter.

Follow the Ad Blue manufacturer 's instruc­
tions for use and storage.

for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourself.

Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel .
.,. After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop¢,&. .
.,. All passengers should
leave the car and move
to a safe location (for instance, beh ind the
guardrail)¢ ,&..
.. Engage the
parking brake to prevent your vehi­
cle from rolling unintentionally ¢,&. .
.. Move
selector lever to position P ¢ ,&. .
.,. If you are towing a trailer, unhitch the trailer
from your vehicle.
.,. Take the
jack and the spare tire* out of the lug­
gage compartment c:> page 236.
A WARNING
You or your passengers could be inju red wh ile
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
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.
- T o help prevent the vehicle from moving
sudden ly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed. When one front wheel is lifted
off the ground, plac ing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from mov ing.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack .
