210 Fuel supply and filling your fuel tank
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
AS TM F852 -86) .
(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalyt ic converter.
Refuelling
Fig. 182 Right rear vehicle side: Opening the fuel filler
flap
Fig . 183 Fuel filler flap with attached fuel cap
When activating the central locking, the fuel
fi ller flap is automatically un locked or locked.
Refuel the vehicle with the ignition switched
off.
Taking the fuel cap off
• Press the left side of the fuel filler flap to
open it
q fig. 182 -arrow-.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filler flap
¢ fig. 183.
Refuelling procedure
• Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go .
• Select a med ium refuelling rate so that the
nozzle switches off automatically when the
tank is full.
Putting the fuel cap back on
• After filling your tank, twist the fuel filter
cap clockwise as far as it w ill go.
• Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filter cap properly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp¢
page 30
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Fai lure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a ce llular telephone while re­
fue ling. Th e electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fueling.
If in exceptional circumstan ces
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable

fuel container in your vehicle. The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the lugga ge compart­
ment, or on the tr unk). Static electrici­
ty can bui ld up while fi lling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.
- Always keep the fi ller nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
help prevent static electricity from dis­
charging and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable .
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852 -86) .
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint.
~ For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full. Do not try to add
more fue l because fuel may spill out . In
add it ion, the expans ion space in the fuel
tank will be fi lled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
Fuel supply and filling your fuel tank 211
@ Tips
-Running your engine while refue lling
may cause vapors to escape or even
cause fuel to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not ind icate the correct fuel
level after refuell ing .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.

a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the

Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 198) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 217
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l

(D Note
D riving w ith an insufficient o il level is like­

(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref­
erably ea ch time you refuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

-Turn the valv e stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjus ted when the tires are cold . The
s li ght ly raised p ressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying .
- Re insta ll the va lve stem cap on the valve.
When should I che ck the tire pres sur e?
The correct tire pressure is espec ially impor­
tant at high speeds. The pressure should
therefo re be checked at least once a month
and a lways before start ing a journey.
When should I adjust the tire p re ssure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels. In addition , you must then
store the new ti re pressu res in the t ire pres ­
sure monitoring system
r::!.> page 246 .
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of contro l, collision, serious persona l injury
or even death.
- When the warning symbo l
[ti] appears in
the instrument cl uster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla ­
t ion can cause increased tire wear and
can affect the handling of the veh icle and
stopp ing ability .
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de ­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tir e pressures fo r all t ires on the vehicle .
T he applicable pressu re va lues are locat­
ed on a stic ker on the drive r's side B-pil­

- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system .
- Always inf late t ires to the recommended
a nd correct t ire p ress ure before dr iv ing

and loss of cont ro l.
- Excess ive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
a nd loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prema turely and the
veh icle w ill not handle well.
- If the tire is not fla t and you do not have
to ch ange a wheel immedia tely, drive a t
red uced speed to the nearest service sta ­
tion to check the t ire p ress ure and add

Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded will not handle
well and is mo re d iff icult to stop. Overloading
can not o nly lead to loss of vehicle control,
but can also damage important parts of the
vehicle and c an le ad to sudden tire fa ilu re, .,..

236 Tire s and whee ls
including a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passenge rs a lso
depends on making s ure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are techn ically referred to as the
vehicle's
Gr oss Veh icl e W eight R ating
("GVWR").
The "GVWR" includes the weight of the basic
ve hicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
i ntended to carry ("seating capacity") with a n
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any luggage in the ve­
h icle.
The
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles .
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar. Your A udi has 4 seating
positions, 2 in the front and 2 in the rear for
total seating capacity of 4. Each seating posi­
tion has a safety belt
9 page 133, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle is limited. The more passen­
gers in the veh icle or passengers who are
heav ier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the veh icle can carry . For the location of the

A WARNING
Overloading a vehicle can cause loss of ve­
h icle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total lo ad be­
ing transpor ted does not make the veh i­
cle heavier than the vehicle's Gross Vehi ­
cle Weight Rating.

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we r ecommend changing to winter
tires.
In some heavy s now areas, local governments
may require true winter or "snow " tires, those
with ve ry deeply cut tread. These t ires shou ld
only be used in pa irs and be insta lled on all
fou r wheels. Ma ke sure yo u pu rchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your veh icle is equipped w it h all-wheel drive,
this will improve tra ct io n du ring w inte r driv­
ing, even with the s tandard tires. However, we
strongly recommend that yo u always eq uip a ll
four whee ls on your vehicle with cor rectly fit­
ted w inter tires or all-se ason tires, when w in ­
te r r oad conditions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances .
Summe r tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must a lways be fitted
on all four whee ls .
Ask yo ur autho rized Aud i dea ler o r qualified
wo rkshop fo r permi tted
winter tire siz es . Use
on ly radia l winter tires.
W inte r tir es lose the ir effectiveness when the
tread is worn down to a depth of 0.15 7 inch
(4 mm) .
Only drive with wi nter tires under winter con­
d it ions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45 °F ( 7 °C).
I f you have a flat tire, see notes on replace­
men t wheel ¢
page 239.
Please always remember that w inter tires may
h ave a lower speed rating than the t ires origi­
n a lly installed on your veh icle at the t ime it
was manufactured. Plea se see ~

page 239 .
A WARNING
Winter t ires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the max imum
speed before driv ing off . Never drive faster
than the speed permitted for yo ur specific
winter tires . This wi ll ca use damage to the
tires leadi ng to an accident and ser ious
personal injury to you and your passen­
gers .
A WARNING ,._.__
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fail ure in­
cluding a blowout and sudden deflation, loss of contro l, crashes and ser ious per­
sonal injuries. Have worn or damaged tires
replaced immediately .
- Wi nter tires have maximum speed rating
that may be lower than your vehicle 's
maximum speed .
- Never drive faster than the speed for
which the w inter or othe r tires installed
on you r vehicle a re rated .
A WARNING
Always a djust yo ur dr iv ing to the road and
traffic cond it ions . Never let the good ac­
celer atio n of the winter t ires and al l-wheel
d rive tempt yo u into ta king ext ra risks. Al­
ways remember:
- W hen braking, an all-wheel drive veh icle
handles in the same way as a front drive
vehicle .
- Drive c arefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires when weather condi­
tions permi t. T hey are qu iete r, do not wear
as quickly and reduce fuel consumpt ion .

Tire pressure
monitoring system
(D General notes
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in­
flation pressure label, you shou ld determine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
p ressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure . Under -inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped w ith a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, the te lltale will
flash for approximately one minute and then remain continuously illuminated. This se- quence will continue upon subsequent vehicle
start-ups as
long as the malfunction exists.
When the malfunction indicator is illum inat­
ed, the system may not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation 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
wheels on your vehicle to ensure that the re­
placement o r alternate ti res and wheels allow
the TPM S to cont inue to function properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the
temperature and pressure in the tires. Theda­
ta is sent from these sensors to the control
module by radio frequency.
The tire pressure monitoring system shows
the current pressures and temperatures of the
tires in the Infotainment system
¢page 247.
It also compares the current tire pressures
with the stored pressures and gives a warning in the driver information system if the tire
pressure is different from what is stored
¢ page 247.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must resave the tire pressures
¢page 248:
- eve ry time the tire p ressu res change, for ex­
ample when the load in the vehicle changes,
- after replacing a t ire, or
- if wheels w ith new wheel sensors are used .
_&. WARNING
-The tire pressu re monitoring sys tem as­
sists the driver in monitoring tire pres­
sures. The driver is responsible for having
the tires inflated to the correct pressure. ..,.

-Do not change the tire pressure when the
temperature of the tire is high. This
could result in serious damage to the tire
and even cause the tire to burst, increas­
ing the risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much . Th is could
cause the tread to separate and even
cause the tire to burst, increasing the
risk of an accident .
- The tire pressure monitoring system
does not warn about damage or defects
in the tire construct ion that could cause
the tire to burst, for examp le. Inspect
your ti res regularly.
@) For the sake of the environment
Low tire pressure increases fuel consump­
tion and tire wear.
(D Tips
-If tires are replaced, the sensors/valves
do not need to be removed or replaced.
Just replace the valve stem and, if neces­
sary, the valve and the wheel electronics.
If you have questions, see your author­
ized Audi dealer or a qualified workshop.
- Using the tire mobility kit can results in
an incorrect display or a malfunction in
the tire pressure monitoring system.
Have the sensors replaced by an author­
ized Audi dealer or a qualified workshop.
