mu st be se lect­
ed so that the ve hicle can be at normal level
¢ page 152, MMI settings .
-If driving in dynamic mode is desired, this
mode
mu st be selected before hitching up
the trailer and before ad justing the tongue
weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to drive under difficult road con­
ditions, you can select offroad or lift mode,
after hitching up the trailer or after adjust­ ing the tongue weight .
- If the veh icle is at
normal level, and you se­
lect offroad mode wh ile traveling at speeds
higher than 22 mph (35 km/h), the veh icle
w ill not be ra ised . Offroad mode will appear
as the active mode in the MM I Disp lay.
- If the veh icle is in offroad mode at

this mode to another mode, dynamic mode
cannot be re-se lected .
{D) Tips
-For vehicles with a factory installed tow­
ing hitch or a trailer hitch that was in­
stalled later accord ing to factory specifi­
cations, the system recognizes "Trailer
tow ing mode" and activates this special
mode automatically, as soon as the elec­
trical connection on the trailer socket is
connected . The mode ceases automat i­
cally when the elect rical connection to
the trailer socket is d isconnected.
- If the tra iler towing mode has been act i­
vated, the vehicle will not drop to the l ow or highway level.

194 Airbag system
-If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@, For the sake of the envi ronment
Undeployed airbag modu les and preten­
sioners might be classified as Perchlorate
Material -special handling may app ly, see
www.dtsc.ca.gov/hazardouswaste/per­ chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts w ith p retens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authori zed
Aud i dea ler is familiar wit h these requ ire­
ments and we recommend that you have
your dealer perfo rm this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem pe rforms in a crash. For example, using
tire-r im combinations not app roved by Aud i,
lowe ring the vehicle, ch anging the stiffness of
the suspension, incl uding the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the ai rbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
p le, increase the force levels measured by t he
sensors and make the airbag system deploy in
crashes in wh ich it would not dep loy if the
cha nges had not been made. Other k inds of
cha nges may reduce the force levels meas­
ure d by the sensors and preven t the a irbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
d river and front passe nger sea t tell the elec­
tronic control module if the safety belt is
l atched or not. I f the safety belt is being used,
the front airbag will deploy at a slightly high­ er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the position where t
he safety be lt is not being
used. It is important that nothing interfere
with the safety be lt b uckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control un it.
A WARNING
=
Changi ng the veh icle's suspension includ-
i ng use of unapp roved tire-rim combina­
tions can change Advanced Airbag per­
fo rma nce and increase the r is k of seri ous
personal injury in a cra sh.
- N ever install suspension components
that do no t have the same pe rformance
chara cter istics as the compone nts o rigi­
na lly ins talled on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
It ems stored between the safety be lt
bu ckle and the cente r console can cause
the sensors in the b uckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air­ bag System from working prope rly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that they are not obstructed .

Driving tips
On poor road and offroad, there is always on ­
ly one motto: Plan ahead and drive slowly!
Please obse rve the fo ll ow ing when d riving
away from paved roads :
.,. Drive on ly on roads and offroad sections
which ma tch the design of yo ur vehicle and
your abilities as a driver. Never take r is ks!
.,. Drive slow ly and plan ahead!
.,. Take into consideration the
ground clear­
an ce
of your vehicle .
.,. Act ivate the
ESC off road mode q page 219
as needed.
.,. Use the
hill descent control q page 220
when dr iv ing down steep sections on h ills .
Unpa ved ro ads and offroad
Drive slowly on unfamiliar roads and unknown
offroad section s, and look out for unexpected
obstacles (e .g. po tholes, rocks, tree s tumps,
etc .) .
To prevent the vehicle from bottoming and
avo id damage to the underbody, you should
drive straight across severe bumps in the
ground with only one side of the veh icle so
that only two of your whee ls cross the bumps .
Drive b risk ly through sandy or marshy offroad
sec tions and do not stop, i f at all possible .
Driving throu gh wate r
Note the following to avoid vehicle damage
when d riving through water, for examp le on
flooded roads:
- The wa ter must not be any higher than the
bottom of the vehicle body .
- Do not dr ive faste r tha n walk ing speed .
Driving on a slope
If you ever find yourself not able to climb a
s lope, do not try to turn around , drive back
down in
r e ver se . Otherwise, you run the r isk

284 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
Fi g. 2 39 Tire tread: tre ad wea r ind icators (TWI)
F ig. 240 Rotat ing t ires for more ev en wea r
Tread Wear Indicator (TWI)
The o rigi na l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
.... N M
c::> fig . 239 running across the tread. Depend ­
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p res sure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 280.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Warranty
& Maintenance booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 240.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 302 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect wheel alig nment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop .
All-wheel driv e
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .
For details see

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains beca use 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 severe ly dam­
age the wheelhouse and other parts of
the veh icle.
(0 Tips
W here snow cha ins 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 whee l bolts is matched to the
factory installed r ims. If different rims are fit­
ted, the cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted
secure ly an d that the brake system f unctions
correctly.
I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l~
page 3 21.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly t ightened.
- Never grease or oil the wheel bolts and the threads in the wheel hubs. They can
become loose w hile driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 2 91
-On ly use whee l bolts that be long to the
rim being installed.
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce t he
risk o f a wheel loss. If the tightening tor­
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi­
cle is mov ing.
If the tig hte ning torque is
too high, the wheel bolts and threads can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
120

Low aspect ratio tires
Your Audi is factory-equ ipped with tow aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb perfo rmance, road feel
and handli ng under a var iety of drivi ng condi­
tions. As k your au thori zed A udi dealer for
more de tails.
The low asp ect ratio of these tires is ind icated
by a nu mera l of
55 or l ess in the tire's s ize
designation. The n ume ra l rep resen ts the ra tio
of the tire's sidew all height in rel ation to its
tread width exp ressed in percentage . Conven ­
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low-aspect-ratio tire s is
particularly sensitive to improper inflation
pre ssure. It is therefore important th at low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and mainta ined. Tire pres-
sures should be checked at least once a .,..

Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
• After you experience a tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop r::::> /.1. .
• All passengers should leave the car and
move to a safe location (for instance, behind
the guardrai l)
r::::> /.1. .
• Engage th e parking brake to prevent your
vehicle from rolling unintentionally
r::::> /.1. .
• Move selector lever to position P r::::> /.1..
• If you are towing a trailer: unhitch the trail­
er from your vehicle .
• Block the diagonally opposite wheel with
the fo ld ing chocks or other objects .
• Take the
jack and the inflatable spare tire
out of the luggage compartment
r::::>page 295.
& WARNING
You or your passengers cou ld be injured
while changing a whee l if yo u do not fol­
low these safety precautions :
- If you have a flat tire, move a safe dis ­
tance
off the road. Turn off the engine,
turn the emergency flashers on and use other warning devices to alert other mo­
torists .
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traff ic .
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the whee l diagonally opposite
the whee l being changed with the fold­
ing chocks or other objects. When one front wheel is lifted
off the ground, plac­
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the inflatable spare tire,
make sure that you replace the flat tire/
wheel in its storage area properly and
tighten the knurled retaining screw se­
curely.
