that are not in the area covered @are not
shown on the MMI display.
We recommend that you p ractice parking with
the rear view camera in a traffic -free location
or parking lot to become familiar with the sys ­
tem, the orientation lines, and their function.
When do ing th is, there shou ld be good light
and weather conditions.
In t he MMI disp lay, objects or vehicles appear
closer or further away if:
- yo u are driving in reverse gear from a level
surface onto an incline, or a downward
s lope,
- you are driving in reverse gear toward pro ­
truding objects,
- the vehicle is carrying too much load in the
rear .

The all-wheel drive concept is designed fo r
high engine power. Your vehicle is exception ­
ally powerful and has exce llent dr iving charac­
ter istics both under normal driving conditions
and on snow and ice . Always read and follow
safety precautions
c> & .
Winte r tir es
When driving in the winter, your ve hicle with
all-wheel drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea­
son t ires) for imp roved driveability and brak­
ing: these tires must be mounted on
a ll four
w heel s.
See also c> page 254, Winter tires.
Tire chain s
Where tire cha ins are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
c> page 255, Snow
chains.
R eplacing wheel s/tire s
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with d ifferent tread depths . For details see
page ~
page 248, New tires and replacing
tires and wheels.
Off-Ro ad dri ving ?
Your Audi does not have enough ground clear­
ance to be used as an off-road veh icle. It is
therefore best to avoid rough tracks and un­
even terrain as much as possible . Also refer to
c> page 193.
A WARNING
Always adjust your driving to road and traf­
fic condit ions . Do not let the ext ra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-whee l dr ive is very ef­
fective, a lways remember that b raking
capacity is limited by tire traction. Yo u
sho uld 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
Int ellig ent technolog y 191
could begin to slide on top of the water
(aquaplaning). If th is should occur, you
will have no warning from a sudden in­ crease in engine speed as w ith 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 time, the bat­
tery is discharged by idling current consumers (e .g. immobilizer). In certain circumstances it
can resu lt in there being insuffic ient energy
available to start the eng ine .
Intelligent energy management in your vehi­
cle handles the distribution of e lectr ica l ener­
gy. Start ing 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 ene rgy management .
Batte ry diagnos is
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 diagnos is is cons id­
ered .
Depend ing on the battery's state of charge,
individual consumers are gradually turned
off .,_ •

Your vehicle is equipped with all whee l drive,
this will improve traction during winter driv­ ing, even with the standard tires. However, we
strongly recommend that you a lways equ ip a ll
four wheels on your veh icle w ith correctly fit­
ted wi nte r tires or all -season tires, when w in ­
ter road conditions are expected. This also im­
p roves the vehicle 's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow .
W inter tire s (snow t ires) must always be fitted
on all four wheels.
Ask your authorized Audi dea ler o r qualified
workshop for permitted
w inter t ire sizes. Use
only radia l winter tires .
Winte r ti res lose thei r effectiveness when the
tread is worn down to a depth of
0 .15 7 inch
(4 mm) .
On ly drive with winter tires under winter con­
d itions. Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45
°F (7 °().
If yo u have a flat tire, see notes on spare
wheel ¢ page 248 .
Pl ease always remembe r th at w inte r ti res may
have a lower speed rating tha n the t ires origi­
n all y ins talled on your veh icle at the t ime i t
was manufactured . Please see ¢ page 250,
Speed roting (letter code) for a Listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code( ¢ page 232) is
on the side wall of the tire ¢ page 248.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed befo re driving off . Never drive faster
than the speed permitted for your specific
w inte r tir es . This will cause damage to the
ti res leading to an ac cident and se rious
pe rsonal i njury to you and yo ur p assen­
gers .
Tire s an d wheel s 255
A WARNING
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause t ire fail ure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sona l injuries. Have wo rn or damaged ti res
replaced immedia tely.
- Wi nte r tires h ave maxim um speed ra ting
that may be lower than yo ur vehicle 's
maxim um speed.
- Never d rive fas ter than the speed for
whi ch the w inter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING
=
A lways ad just yo ur driving to t he roa d and
traffic conditions. Never let the good ac­
celeration of the winter tires and a ll 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
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
-
Snow cha ins may be fitted only to the fro nt
whee ls, and on ly to certain tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow chains can be used.
The snow chains must have low-p rofile links
and must not be th icker than
0 .53 inch
(13 . 5 mm) , in cl ud ing t he lo ck.

be fitted over the wheel bolts. These are
available 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 .
- 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
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
corr ect 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
secu rely and that the b rake system functions
correctly . In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model ¢
page 285.
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.
Q) Note
The specified torque for the wheel bolts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi ­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop .

.&, WARNING
- If the t ire pressure indicator appears in
the instrument cl uster d isplay, one or
more o f your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle 's t ire
pressure label~
page 234 . Driving on a
significantly under-inflated tire ca uses
the tire to overhea t and can lead to tire
failure. Under-inflation also is likely to impair the vehicle 's handling and stop ­
ping ability.
- The driver is responsible for mainta ining
the correct tire pressures. You must check the tire pressures regularly .
- Under certain cond itions (such as a spor ­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be de layed .

Using the spa re tire (compact spare tir e)
The compact spare tire is only intended for
emergenc ies until you can reach a repair shop.
Replace it as quickly as possible with a stand­
ard wheel and t ire .
There are some restrictions on the use of the
compact spare t ire . The compact spare t ire
has been des igned specifically for your type of
veh icle.
It must not be swapped with a com­
pact spare tire from another type of veh icle.
Snow chains
For technical reasons, the use of snow chains
on the compact spare tire is
not p erm itted .
If you do have to drive with snow chains and a
front tire fails, mount the spare whee l w ith
tire instead of a rear tire. Install the snow
chains on the rear t ire and use it to replace
the defective front tire.
.,&. WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dica to rs.
- If the spare tire is mo re tha n 6 years o ld,
use it only in an emerge ncy and w it h ex­
tr eme cau tion a nd careful d riving .
- T he spare tire is intended only fo r tem­
porary and sho rt-term use.
It should be
rep laced as soon as possib le w ith the
normal wheel and t ire.
- After mount ing the compac t spare ti re,
the tire pressu re must be che cked as
soon as possible . The tire pressure of the
compact spa re tire m ust be 4 .2 bar; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than 50 mph (80 km/
h) . You risk having an accident.
What do I d o now ? 261
-Avoid full-thrott le acceleration, heavy
brak ing, and fast cornering. You risk hav­
ing an accident .
- Never drive using more than one spare
wheel and tire. You r isk having an acci­
dent .
- Normal summer or winter t ires must not
be mounted on the compact spare w heel
rim .
- For technical reasons, the use of tire
chains on the spa re tire is not permitted .
If it is necessary to drive with t ire chains,
the spare wheel must be mounted on the
fro nt axle in the event of a flat in a rear
tire. The newly available fron t wheel
m ust then be inst alled in place of the
rea r whee l w ith the flat tire. Installing
the tire chain before mounting the whee l
a nd tire is recommended.
- Loose items in the passenger compart ­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the spare tire or jack and
