Deactivating the convertible locking
retractor
The convertible locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way back into the re­
tractor .
~ Press the red button on the safety belt buckle.
The belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position. The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints.
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deact ivate this feature. If the
convert ible locking retractor is not deactivated,
the safety belt w ill gradually become tighter and
uncomfortable to wear.
_& WARNING
-
Improperly installed chi ld safety seats in­
crease the risk of serious personal injury and
death in a collision.

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicab le way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children". In
Canada, the terms "top tether" with "lower uni­
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r without one can seriously impair the per­
formance of the child restraint and its ab ility to
pro tect the child in a collision. Installing a child
restra int that requi res a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats w ith hook-on or ..,.

-Never secure or attach any luggage or other
items to the
LATCH lower anchorages .
- Always read and heed the important infor­
mation about child restraints in this chapter

Selective catalytic
reduction (AdBlue)
General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve­ hicle. The Ad B lue usage accounts for approxi­
mately 1.0% to 2.5% of the diesel fuel that is
used.
When a message about refi lling the AdBlue ap­
pears in the instrument cluster display, you must
ref ill the Ad B lue yourself or have it refilled by an
authorized Audi dealer or authori zed Audi Service
Facility
c> page 301.
(l} Tips
- The d isp lay indicates the distance rema ining
that can be driven¢
page 300. If the Ad Bl­
ue tank is completely empty, the engine will
not start again after the ignition is switched
off .
- Ad Blue is required by law to operate th is ve­
hicle.
Messages in the instrument cluster display
App lies to: vehicles with selective cata lytic reduction
The display indicates if the Ad Blue level is low or
if there is a system malfunction .
Ad Blue level low
You will be informed in the instrument cluster
display if the Ad Blue in the tank drops below a
certain level. Add at a minimum the amount of
Ad Blue shown in the message:
• Refill with at least x qt (l) Ad Blue . Range
x mi (km)
This message appears when there is only enough
AdBlue left to drive the distance indicated in the
instrument cluster. Fill the AdBlue.
• Refill with at least x qt (I) AdBlue . No en­
gine start in x mi (km ). See owner's manual

Checking and Filling
the engine. See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- Ad Blue 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 . Ad Blue 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 Ad Blue to come into contact
with clothing.
If there is contact with the
fluid , flush immediately with plenty of wa­
ter.

Disconnecting the battery terminals
Some ve hicl e fu nctions (power window regula ­
tors, for examp le) are lost if the batte ry te rm i­
nals a re disconnected . These f unc tions have to be
relearned after the battery term inals are con­
nected again . To p revent this, the battery should
o nl y be disconnected from the vehicle electrical
system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not d rive yo ur vehicle ove r a period of

Wheels
bolts and a special procedure. You must never
repair or disassemble them ¢
.&..
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 348, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
.,. Use winter t ires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lowe r with winter tires
q ,&. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 327.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .16 in (4 mm) . The characteristics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread .
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
332
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol are permitted .
Snow chains
Snow cha ins not only improve the driving in win­
ter road condit ions, but also the braking.
.,. Only install snow chains on the
front wheels .
This applies a lso to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi deale r or author­
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 in (13 .5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow. Otherwise , you could impair driving
ability and damage the tires .
