- Some of the equipment or features
shown in the genera l ill ustration may be
standard equ ipment on your vehicle or
may be opt ional equ ipment depending
on you r model. Always ask your autho r­
ized Aud i dea le r i f you have a quest ion
about your ve hicl e.

78 On the road
regular intervals . Any associated noises
are norma l.
Parking
• Press the brake peda l to stop the vehicle .
• Pull the switch(®) to set the parking brake .
• Move the selector lever to P.
• Turn the eng ine off ¢.&_ .
• When on incl ines or declines, turn the steer­
i ng wheel so that your vehicle will roll into
the curb if it begins to move.
_& WARNING
- When you leave your veh icle - even if on­
ly briefly - always take the ignition key
with you . This applies particu la rly when
children remain in the veh icle. Otherw ise
the ch ildren could start the engine, re­
lease the parking brake or operate e lec­
trical equipment (e.g . power windows) .
The re is the risk of an accident .
- When the vehicle is locked, no one - par­
t icu la rly not children should remain in
the vehicle . Locked doo rs make it more
difficult for emergency wor kers to get in ­
to the vehicle - putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon
starting .
Stopping and applying park ing brake
• Pull the switch© to apply the park ing
brake .
Starting and automat ically releasing the
parking brake
• When you start to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move .
When stopp ing at a traff ic signa l or stopp ing
i n city traffic, the parking brake can be ap ­
plied . The veh icle does not have to be held
with the footbrake. The par king brake e limi­
n ates the te ndency to creep with a drive ra nge engaged. As soon as yo
u drive off as usu a l,
the parking brake is re leased automatically
and the vehicle starts to move .
Starting on slopes
When starting on inclines, the starting assist
prevents the vehi cle from u nintent ionally roll ­
ing back . The braking force of the parking
brake is not re leased unti l sufficient driving
f orce has been built up at the wheels.
(D Tips
F o r safety reasons, the parking brake is re ­
l eased a utomatically on ly when t he d riv­
er's safety belt is engaged in the buckle.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks.
• In an emergency, pu ll the switc h C®> and
continue to pull it to s low your vehicle down
with the parking b rake .
• As soon as you re lease the switch «:El) or ac -
celerate, the brak ing process stops.
If you pu ll the switch «:El) and hold it above a
speed of abo ut 5 mph (8 km/h), the eme rgen­
cy brak ing f unct ion is initiated . The vehicle is
braked at all four whee ls by activating the hy­
draulic brake system . The brake performa nce
i s sim ila r to making an emergency stop
c::> .&. .
In order not to act ivate the eme rgency brak­
ing by mistake, an audib le warning tone (bu z­
zer) sounds whe n the switch(®) is pulled . As
soon as the sw itch
®) is released, or the accel­
erato r peda l is depressed, eme rgency b raking
stops.
_& WARNING
E mergency br aking should only be u sed in
a n emergency, when the norma l foot bra ke
has fai led or the brake pedal is obstruc ted.
Using the parking brake to pe rform eme r­
gency b raking will s low your veh icle down
as if you had made a full brake application.

differential lock (EDL), dynamic steering* and
selective whee l torque control. ESC is switch­
ed on all the t ime. In certa in situations when
you need less traction, you can switch off ASR
by pressing the button
[ill c> page 191,
fig. 180. Be sure to switch ASR on again when
you no longe r need less traction .
Anti-loc k br ak ing system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard brak ing. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal ind icates that
the system is he lp ing you to b rake the vehicle.
B rake as sist sys tem
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quick ly in emer ­
gency situations. You must p ress and hold the
b rake pedal until the situation is over. I n
vehicles w ith adaptive cru ise cont rol*, the
b rake assist system is more sens it ive if the
d istance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the d rive
wheels begin to spin and ad apts the fo rce to
the road condit ions. This makes i t easier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the d rive powe r to the other d rive
wheel o r whee ls if the vehi cle is equipped wi th
a ll-w hee l drive* . This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automat ica lly swit ches
off to help keep the brake o n the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
norma l.
Dynamic steering*
On vehi cles w ith dy namic stee ring*, ESC helps
stabilize the steering i n critical s ituations.
Selective wheel torque control
T he sele ctive whee l torq ue con trol ope rates
when driving through c urves . The front whee l
on the inside of th e curve o r both wheels on
the inside of the curve are braked selectively
as needed. This minimizes sliding in the front
whee ls and allows for more precise driving
t hr ough curves. The appl icable system may
not act ivate when dr iv ing in wet or snowy con­
ditions .
,&. WARNING
-ESC, ABS, ASR, EDL, dy namic steeri ng*
and the select ive wheel torq ue con trol
c a nnot ove rcome the laws of physics.
T his is especially important on slippery
or wet roads.
If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic
and wea ther conditions. The risk of los­
ing con trol of t he vehicle increases when
d riving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, ASR, EDL, dynam ic steering* and
the selective wheel torque contro l can­
not prevent collisions .
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow .
The drive wheels can spin eve n w ith
these assistan ce systems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheels are equipped with identi­
cal tires. D iffe ren t tire si zes can lead to a
reduction in engine power.

Driving with your
quattro
With all-wheel drive, all four wheels are driv­
en .
General information
With all-wheel drive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See also
t::;> page 189.
A center differential distributes the driving
power variably to the front and rear axle. It
works together with selective wheel torque
control, which activates when driving through
curves
t::;> page 190 . With the sport d ifferen­
tial*, power distribution to the rear wheels is
va riable and can be adjusted with drive select
¢page 96.
The all-wheel drive concept is designed for
hi gh engine power. Your vehicle is exception­
ally powerful and has exce llent dr iv ing charac­
teristics both under normal driving conditions
and on snow and
ice. Always read and follow
safety precautions
t::;> .& .
Winter tires
When driving in the w inter, your ve hicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
all four
wheels. See also ¢ page 243, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 244, Snow
chains.
Replacing wheels/tires
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid tires
with different tread depths. For details see
page
t::;> page 239, New tires and replacing
tires and wheels .
Intelligent technology 195
Off•Road driving?
Your Audi does not have enough g round clear­
ance to be used as an off-road vehicle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible. Also refer to
¢page 199.
A WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel drive is very ef­ fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions - risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine .
If a vehicle with a conventiona l energy system
is not driven for a long period of tim e, the bat­
tery is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can resu lt in there being insufficient energy
available to start the eng ine.
Intelligent energy management in your vehi­
cle handles the distribution of e lectrica l ene r­
gy. Starting ability is markedly improved and
the life of the battery is extended .

Speed rating (letter code)
means the speed at wh ich a tire is des igned to
be driven for extended periods of t ime . The
ratings range from 93 mph (150 km/h) to
186 mph (298 km/h) ¢
page 240 . You may
not find this information on all tires because
it is not required by law.
The speed rating letter code, where applica­ ble, is molded on the tire sidewall and indi­
cates the maximum permissible road speeds
¢ &. in Winter tires on page 243.
Tire pressure monitoring system
means a system that detects when one or
more of a vehicle's tires are underinflated and
illuminates a low tire pressure warn ing te ll­
tale .
Tread
means that portion of a tire that comes into
contact with the road.
Tread separation
means pulling away of the tread from the tire
carcass .
Treadwear indicators (TWI)
means the projections within the princ ipal
grooves designed to give a visual indication of
the degrees of wear of the tread. See
¢
page 237, Tread Wear Indicator (TWI) for
more informat ion on measuring tire wear.
Uniform Tire Quality Grading
is a tire information system developed by the
United States National Highway Traffic Safety
Admin istration (NHTSA) that is designed to
help buyers make relative comparisons among
tires . Th e U TQG is not a safety rating and not a
g ua ran tee that a tir e will las t for a prescribed
number of mi les (kilometers) or perform in a
certain way. It simply gives tire buyers addi ­
tional information to combine with other con-
Tires and wheels 231
siderations, such as price, brand loyalty and
dealer recommendations. Under UTQG, tires
are graded by the tire manufacturers in three
areas : treadwear, traction, and temperature
resistance. The UTQG informat ion on the tires,
molded into the sidewalls .
U.S. DOT Tire Identification Number (TIN)
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federa l standards. The next two
numbers or letters ind icate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example,
DOT ... 2213 ...
means that the tire was produced in the 22nd
week of 2013. The other numbers are market­
ing codes that may or may not be used by the
tire manufacturer. This information is used to
contact consumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and luggage load p lus
150 lbs . (68 k ilograms) times the vehicle's to­
tal seating capacity as listed on the label lo­
cated on the driver's side B -pillar .
Vehicle maximum load on the tire
means that load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is
determined by distributing to each ax le its
share of the curb weight, accessory weight,
and normal occupant weight (distr ibuted in
accordance with table below¢
page 232)
and dividing by two.

symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced. Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire p ressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
c::> page 234.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tir es on your vehicle to have the
same se rv ice life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- T ire rotation inte rva ls may differ from the
vehicle serv ice intervals outlined in your
Warranty
& Maintenance booklet.
- T he longer one tire is used in one location
on the vehicle, the more it wears at certa in
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front whee ls com­
pared to all-whee l drive (quattro).
- Please rotate ti res as shown
c::> fig. 198.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 2 59.
Wheel balancing
The wheels on new vehicles are balanced .
Ho wever, various situations during everyday
driving can cause them to become unbal­
anced, resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering, suspension
and tires . A wheel must a lso be rebalanced
when a new tire is installed. Incorrect wheel alignment
Incorrect
wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
wheel alignment checked by an a uthorized
Audi dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see
c::>page 195.
_8 WARNING
-Sudden tire fa ilure can lead to loss of con-
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn t ires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, o il, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fai l suddenly, especially at high
speeds. Tires that are more than 6 yea rs
old can only be used in an emergency
and then w ith specia l care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

manufacturers also must indicate the materi­
als in the tire, which include steel, nylon, pol­
yester, and others.
M ax imum Load R atin g

Maximum Permissible Inflation Pressur e
This number is the greatest amount of air

_& WARNING ,...__._
- Using incorrect or unmatched tires and/
or whee ls or improper tire and whee l
combinations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of original
factory-installed tires or other combina­ t ions that have been spec ifically ap­
proved by the vehicle manufacturer.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds . Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds .
- Never mount used tires on your vehicle if
you are not su re of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radia l
tires of the same type, size (rolling cir­ c u mference) and the same tread pattern.
Driving with different tires red uces veh i­
cle handling and can lead to a loss of
control.
Tire s an d wheel s 241
-If the replacement tire is not the same as
the t ires that are mounted on the veh icle
- for example with winter tires - only use
the replacement tire for a short per iod of
time and drive with extra care . Refit the
normal road whee l as soon as safely pos­
sible.
- Never drive faster than the max imum
speed for which the tires on you r vehicle
a re rated because tires that are dr iven
faster than thei r rated speed ca n fa il
suddenly .
- Ove rloading tires ca use heat build-up,
sudden tire fa ilure, including a blowou t
and sudden deflation and loss of cont ro l.
- Temperature grades apply to ti res that
are properly inflated and not over or un ­
derinf lated .
- F or technical reasons it is not always
possible to use whee ls from other
vehicles -in some cases not even whee ls
from the same veh icle mode l.
- If you install wheel trim discs on the ve ­
hicle wheels, make sure that the air flow
to the brakes is not b locked. Reduced air­
flow to the brakes can them to overheat, increas ing stopping d istances and caus­
ing a co llision.
- Run flat tires may only be used on
veh icles that were equipped with them
at the factory . The veh icle must have a
chassis designed for run flat tires . Incor­
rect use of ru n flat ti res can lead to vehi­
cle damage or accide nts. Che ck with an
author ized Audi dealer or tire spe cialist
to see if your vehicle can be eq uipped
with run flat tires . If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles. Th is can hold tr ue for wheels
of the same vehicle type. .,..

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 240,
Speed rating (letter code)
for a List ing of the
speed rat ing letter codes and t he maxim um
speed at w hic h the tir es can be driven.
Tire s an d wheel s 243
The speed rating letter code(¢ page 231) is
o n the side wall of the tire~
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 .

246 Tires and wheels
Refer to ¢page 243 for mo re detailed infor­
mation regarding winter tires .
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. ..,.

11. Deactivate the vehicle jack mode* in the
MMI:

A WARNING
Always read and follow all WARNINGS and
information
c:> .&. in Raising the vehicle on
page 257
and c::> page 259.
After changing a wheel
A wheel change is not complete without the
doing the following .
.. Always store the vehicle tool kit, the jack*
and the replaced tire in the luggage com­
partment
c::> page 129.
.. As soon as possible, have the tighten ing
torqu es
on all wheel bolts checked with a
torque wrench . The correct tightening tor ­
que is 90 ft lb (120 Nm) .
.. Have the flat tire
re pl ace d as soon as poss i­
ble.
@ Tips
- If you notice that th e whee l bolts are
corroded and difficult to turn wh ile
changing a t ire, they should be replaced
before you check the tighten ing torque .
- Drive at reduced speed unt il you have the
tightening torq ues checked .
- After changing a wheel, the tire pressure
i n a ll four tires must be checked/cor rect­
ed and the tire pressure mon itoring indi­
cator must be stored in the MM I

What do I do now ? 255
Wheels with wheel bolt caps
Applies to vehicles: with wheel bolts with caps
The caps must be removed first from the
wheel bolts before the bolts can be un­
screwed .
