222 Fuel supply and filling your fuel tank
The AdBlue is stored in a separate tank in the
ve hicle . The AdBlue usage accounts for a p­
prox imately 0.5% to 1.2% of the diese l fuel
that is used.
You must refill the AdBl ue or have it refilled
by your authorized A udi dealer or qualif ied
wo rkshop as soon as the Ad Bl ue refill mes­
sage appears in t he instrument cl uster

@ Tips
-The oil pressure warning display. i s
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
structions about how to measure oil con­
sumption accurately.

tire failure and loss of
control.
-Excessive speed and/over­ loading can cause heat
build -up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem caps on all wheels are secure­
ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.

Tires and vehicle load limits
'
There are limits to the amount of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are
not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle .
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum ""

loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used .
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(j) Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all-wheel drive .

2 70 T ire s and wheel s
through or over such obstacles can damage
your tires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer. Rep lace a damaged
t ire as soon as possible.
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of air and underinflation, wh ich could eventu­
ally cause t ire failu re. If you bel ieve that a
t ire may have been damaged, replace the
t ire as soon as possible.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than
othe r cho ices .
Reduced performance in winter /co ld
season condition s
All tires are des igned for certain pu rposes.
The low aspect ratio, ultra high pe rformance
tires orig inally installed on your veh icle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable for cold, snowy or icy weather conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehi cle, or their equ ivalent.
Refer to¢
page 267 for more deta iled infor­
mat ion regarding winter tires.
Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r on the vehicle
p lacard or tire inflation pressure label. (If your vehicle has tires of a diffe
rent size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determ ine
the proper t ire inflation pressure for those
t ires).
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
t ires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper p ressu re. Driving on a sig nifican tly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fai lure . Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined w ith
the low tire pressure telltale . When the sys­
tem detects a malfunction, the telltale will
flash fo r approxima te ly one m inute and then
rema in continuously illum ina ted. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indica to r is illum inat­
ed, the system m ay not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, incl uding the insta llation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
whee ls on you r vehicle to ensu re that the re­
placement o r alternate ti res and wheels a llow
the TPM S to cont inue to func tion p roperly.
