TPMS Tire pressure monitoring system
malfunction
A malfunction can have various causes .
If the II] warn ing light in the instrumen t clus­
ter flashes for approximately one minute and
then remains continuously illuminated and
addit ionally the
11@18' symbo l appears in the
d isplay, the t ire pressure monitoring system is
not available . The text

ma lfun ction
appears in the disp lay . This can
have va rious causes . -
A whee l sensor or other component may
have fai led .
- Dur ing initialization the sys tem has detect ­
ed more than 4 wheels on the vehicle , for
examp le w hile d riving next to another car
w ith a t ire pressure monitoring system.
- Audi rep lacement parts were not used .
- If snow cha ins a re being used, system func-
tion can be compromised due to the shie ld ­
ing properties of the chains.
- The tire pressu re monitoring system may
not be avai lab le because of a radio malfunc­
tion.
- T ransmitters with the same freq uency, such
as radio headphones in the vehicle or radio
equ ipment, can cause a temporary disrup­
tion of the system through excessive elec­
tromagnet ic fie lds .
- Eliminate the interference if yo u can and
then proceed as follows: Turn off the eng ine
for 20 minutes. Then drive another 10 mi­
nutes. If the war ning light comes on again,
you shou ld contact yo ur autho rized Aud i
dea le r i mmediately to have the prob lem cor­
rected .
- Do not use commerc ia lly available t ire sea l­
ants. Othe rwise, the elec trical components
of the tire pressure mo nitor ing system will
no longer work properly and the sensor for
the t ire press ure monito ring system wi ll
have to be rep laced by a qualified wo rkshop.

90 Parking system
Rear view camera coverage area
The rearview camera shows you the area be­hind your vehicle in the navigation system dis­
play. This area roughly corresponds to the
area in
¢ fig. 94 and (!) ¢fig. 95. Orientation
lines and colored surfaces are projected in the
area shown, which can help you with parking
and maneuvering. Objects that are located in
an area that is not captured by the camera@
¢ fig. 95 and that are closer to the bumper
will not appear on the navigation system dis­ play.
We recommend that you practice parking with
the rearview camera in a traffic-free location
or parking lot to become familiar with the sys­
tem, the orientation lines, and their function.
There should be sufficient light and good
weather conditions when doing so.
In the navigation system display, objects or
vehicles appear closer or further away if:
Objects or vehicles appear closer or farther
away in the navigation system if:
- you are driving in reverse gear from a level
surface onto an incline, or a downward
slope,
- you are driving in reverse gear toward pro-
truding objects.
The accuracy of the o rientation lines and blue
surfaces diminishes if:
- the rearview camera does not provide a reli­ able image, for example, in poor visibility
conditions or if the lens is dirty,
- the image on the screen is not visible due to
sun glare and reflection .
Caring for the rearview camera lens
The rearview camera is located in the center
of the vehicle above the rear license plate bracket. In order for the rearview camera to
function properly , the camera lens must be
kept clean and free of snow and ice .
- Dampen the lens with a household alcohol­
based glass cleaner , and clean the lens with
a dry cloth. - Remove
snow with a hand brush and ice
preferably with a de-icing spray
¢ (D .
A WARNING
--
-The parking system cannot replace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving maneuvers .
- Sensors have blind spots in which objects
cannot be detected. Pay special attention
to small children and animals because
the sensors cannot always detect them .
- Always keep your eyes on the vehicle's
surroundings, using the rearview mirror
as well.
- Do not allow yourself to be distracted from traffic by the rearview camera pic­
tures in the navigation system display .
- If the position and the installation angle
of the camera has changed, for example,
after a rear end collision, do not continue
to use the system for safety reasons .
Have it checked by an authorized Audi
dealer or other qualified workshop.
(D Note
-Low obstacles already s ignaled by a
warning can disappear from the system's detection range as they are approached
and will not continue to be signaled. Ob­
jects such as barrier chains, trailer draw
bars, narrow painted vertical poles or
fences may not be detected by the sys­
tem, posing risk of damage.
- Never use warm or hot water to remove
snow or ice from the rearview camera
lens because the lens could crack.
- Never use products that are abrasive
when cleaning the lens.

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 150.
Winter tires
When driving in the winter, your vehicle 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.
Snow chains
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
Q page 204 , Snow
chains.
Replacing wheels/tires
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles with
all-wheel drive
<=> page 199.
A WARNING
-Always adjust your driving to road and
traffic conditions. Do not let the extra
safety afforded by all-wheel drive tempt
you into taking extra risks.
- Although a ll-wheel drive is very effect ive,
always remember that braking capacity
is limited 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
cou ld beg in 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 vehicle. 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 conventional energy system
is not driven for a long per iod of time, the bat­
tery is discharged by idling current consumers
(e .g. immobi lizer). In certain circumstances it
can resu lt in the re being insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cle handles the distribution of e lectr ical ener­
gy. Starting ability is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is standing.
With the ign ition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

204 Tir es and whe els
eq uip all four wheels on your vehicle with cor ­
rectly fitted winter tires or all-season tires,
when winter road conditions are expected. This a lso improves the vehicle's braking per­
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itor ing sensors
must be installed on all fou r winter tires for
the tire pressure monitoring system to func­
tion proper ly ~
page 201 .
Ask your authorized Aud i dea ler or qualified
wo rkshop for permitted
winter tir e sizes. Use
only radia l winter tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with winter tires under winter con­
d itions . Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inte r tires may
have a lower speed rating than the t ires origi­
na lly installed on your veh icle at the t ime i t
was manufactured. Please see
r:!> page 200 ,
Speed roting (letter code) for a list ing of the
speed rating letter codes and the maximum
speed at which the tires can be driven.
The speed ra ting letter code
(~ page 191) is
on the s ide wall of the tire
r::!> poge 199.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an accident and serious
personal in ju ry to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sonal injuries. Have wo rn o r damaged ti res
r eplaced immediately.
- W inte r ti res have maxim um speed rating
that may be lower than your vehicle 's
maximum speed.
- Never drive fas ter than the speed for
which the win ter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING ~
A lways ad just your driving to the road and
traffic condit ions. 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 veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully 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 permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
S now cha ins may be fitted only to the rea r
whee ls, and o nly to certa in tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow c hains ca n be used.
T he snow chains must have low-profile links
and must not be t hicker than 0 .53 inch
(13 .5 mm), in cl ud ing the lock.
Remove wheel center covers before putt ing
snow c ha ins on your vehicle~@ . For safety
reasons cover caps must then be f itted over

the wheel bolts. These are available from au­
thorized 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.
- 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.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 211.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago­
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel
and handling under a variety of driving
