Level Adjustment when towing a trailer
- Before hit ching up the trailer and before ad
jus ting the tongue weight at the trailer, the
automatic or comfort mode
must be se lect
ed so that the ve hicle can be at normal level
¢ page 157, MMI settings.
-If driving in dynamic mode is desired, this
mode
must be selected before hitching up
the trailer and before adjusting the tongue
weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to dr ive under difficult road con
ditions, you can select offroad or lift mode,
after hitch ing 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 MMI Display.
- If the veh icle is in offroad mode at
high level
1 ,
it automatically lowers to normal level
when the vehicl e is t ravel ing at speeds ex
ceeding approximately 31 mph (SO km/h).
The vehicle is automatical ly raised to
high
level 1
again when the traveling speed falls
be low approx imately 25 mph (40 km/h).
Restrictions when operating with a trailer
When operating w ith a trailer, the lift mode
can only be selected up to about 12 mph (20
km/h) . Lift mode is automatically cance led
again when a speed of about 25 mph (40 km/
h) is exceeded.
If t he vehicle is in automatic, comfort, offroad
or lift mode before the trai ler towing mode is
activated, the dynamic mode cannot be acti
vated .
If t he vehicle is in dynamic mode before tow-

(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 specia l
mode automatically, as soon as the elec
trical connection on the trailer socket is
connected. The mode ceases a utomat i
ca lly when the elect rical connection to
t h e trai ler socket is d isconnected.
- If the tra iler towing mode has been acti
vated, the vehicle will not drop to the

@ For the sake of the environment
Undep loyed airbag modu les and preten

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag Sys
tem pe rforms in a crash. For example, us ing
tire -r im combinations not approved by Aud i,
l owering the vehicle , changing the stiffness o f
the s uspension, incl uding the springs, s uspen
sion struts, shoc k absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam
p le, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in wh ich it would not dep loy if the
changes had not been made. Ot he r kinds of
changes may redu ce the force levels meas
ured by the sensors and prevent the a irbag
from deploying when it sho uld .
The senso rs in the safety belt buckle fo r th e
dr iver and front passenger sea t tell the elec
tronic control module if the safety belt is
l a tched o r not.
If 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 seati ng position where the
safety belt is being used but will inflate at the
A irba g sy stem 199
position where t he safety be lt is not be ing
u sed. 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
C hanging the vehicle's suspension includ
ing use of unapprove d tire-r im combina
tions can cha nge Advanc ed Airbag per
fo rman ce an d in crease the r isk of se rious
person al injury in a crash.
- Never install suspension components
tha t do no t have the same pe rforman ce
characteris tics a s the co m ponen ts origi
na lly installed on yo ur vehicle.
- N ever use tire-rim combin ations tha t
have not been approved by Audi.
A WARNING
-
Items stored between the safety be lt
b uckle and the cente r console can cause
the sensors in t he b uckle to send the
wrong information to the e lectronic con
trol module and prevent the Advanced Air bag System from working properly.
-A lways make su re 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 isks!
.,. 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 225
as needed.
.,. Use the
hill descent control q page 226
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

2 90 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.

ing 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 ressure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For t his
reason, tire pressure must be checked at least
once a month
c::> page 2 86.
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 recommen d that t he
front and rear t ires are rotated according to
the tire manufact urer'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 fro nt w heels com
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 254.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 308.
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unba l
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avo id excessive wear on steering, suspension
and t ires. A whee l m ust also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect w heel alig nment can cause exces
sive tire wear, impairing the safety of the vehi
cle . If tires show excessive wear, have the
whee l alignment checked by an aut horized
Audi dealer or qualif ied workshop .
All-wheel drive
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type.

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
veh icles w ith all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled r ims. If different rims are fit
t e d, 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 32 7.
& 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 297
-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.

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 that 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 .,..
