Tongue weight
The maximum permitt ed tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded .
I f the tongue we ight is too low, th is affects t he
trailer's handling. For driv ing safety, we recom­
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example, by distributing the cargo in the
trailer correctly.
You can determine the tongue weight, for exam­
p le, with a bathroom scale or a public weigh sta ­
tion .
The permitted tongue we ight of your veh icle can
be found in the vehicle documentation or in
¢page 370.
Load distribution
Poor cargo load and distribution can negatively
i mpact ve hicle handl ing .
-Store objects preferably in the vehicle luggage
compartment. The vehicle shou ld always carry
the heaviest possible load and the trailer
shou ld have the lightest possible load.
-Distribute the load in the tra iler so that the
heavy objects are as close to the axle as possi­
ble.
-Secure objects from slid ing out of p lace.
-Utilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the t ire pressure
sticker¢ page 335 .
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­
mendation .
W inter tires should be mounted on the vehicle
and on the trailer during winter temperatures .
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you must attach addit ional exterior m irrors. Adjust
them so you have a sufficient visibility behind
you .
Trailer towing
Exterior lighting
Follow the legal regu lations rega rding the light ­
ing equipment on your trailer. Contact an author­
ized Audi dea ler or authorized Audi Service Facili­
ty for more information.
Before starting to drive , check all lighting eq uip­
ment on the hitched trailer.
T he headlight range cont rol adjusts automat ica l­
ly to the light range of the headlights .
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves . Howeve r, th ey must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The air suspens ion must be at the standard vehi­
cle height before you set the tongue weight on
the tra iler and hitch the
trailer ¢@ , ¢page 128,
Raising/lowering the vehicle.
For vehicles with a factory-installed trailer hitch,
the a ir suspension trailer mode w ill automatically
switch on if you connect the trailer cable to the
socket.
For vehicles with a retrofitted trailer hitch, you
must sw itch on the a ir suspension trailer mode
manua lly . Select in the Infotainment system:
IMENU I button> Vehicle> left cont rol button>
Vehicle settings > Air suspension: trailer. Switch
i t off again after towing a tra iler .
You can also sw itch off trailer mode manually
wh ile dr iving, for example, whe n using a bicycle
rack system.
If you have to dr ive through d ifficult road cond i­
tions, you can ra ise the vehicle again after hitch­
i ng the tra iler o r after adjusting the tongue
we ight.

Assistance systems
Engine and automatic transmission
Depending on the mode , the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator peda l
movements. In the sporty
Dynamic mode, the
transmission shifts at higher speed ranges.
Air suspension*
The air suspension* is an electronically-control ­
led air suspension and damping system. The
ad­
justment depends on the driving mode selected,
steering movements, the driver's braking and
ac­
celeration, and as the road surface, vehicle speed
and load. The veh icle ground clearance depends
on the mode selected and the speed .
The ground clearance increases significantly
when the vehicle is in the
Allroad mode . At
speeds from approximate ly SO mph (80 km/h) to
75 mph (120 km/h), the ground clearance
re­
duces in stages . When the speed decreases, the
ground clearance increases aga in automat ically .
The ground clearance is the lowest in
Dynamic
mode.
Suspension control*
The suspension control* uses sensors to record
information regard ing steering movements,
braking and acceleration operations by the driv­
er, road surface, dr iv in g speed, and load. This
makes it possible to adapt damping to the driv­
ing situation near ly in rea l time. With drive
se ­
lect, you can adjust the suspension contro l to be
sporty
( Dynamic ), comfortab le (C omfort ) or bal­
anced
(A uto ).
Steering
The power steering adapts. Ind irect steer ing that
moves easi ly as in
Comfort mode is especia lly
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
The following applies to vehicles with dynamic
steering* : the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to prov ide improved vehicle con­
trol. At reduced speeds, steering is more direct in
126
order to keep the steering effort as minima l as
possible when the driver is maneuvering the ve hi­
cle. At low and average speeds, dynamic steer ­
i ng* addit iona lly prov ides more respons ive steer­
i ng performance.
Sport differential*
As a component of the all whee l drive system
(quattro)
r=!> page 144, the sport differentia l dis ­
tributes the driving power to the rear axle
de­
pending on the s ituation. The distr ibut ion of
power varies depending on the selected mode
from moderate
(C omfort ) to sporty (Dynamic ).
The goal is a high level of ag ility and ability to ac­
celer ate on curves. The vehicle is very respons ive
to stee ring.
Adaptive cruise control (ACC)*
The behavior whe n accelerating can be adjusted
from comfortable to sporty, depending on the drive select mode . Adaptive cruise control also
r esponds to the driv in g behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty .
@ Note
Applies to: vehicles with a ir suspension
- Make sure there is enough clearance above
and below the vehicle when pa rking. Th e
height of the vehicle (ground clearance) can
change once it is parked due to temperature
fluctuations, changes to the load conditions
and changes to the driving modes.
- When transporting the vehicle on a car
car­
rier, train, ship or by other means, only tie
the vehicle down at the running sur face of
the tires, which is the outer c ircumference.
Securing the vehicle at the axle compo­
nents, suspension struts or tow ing eyes is
not perm itted because the pressure in the
air suspens ion struts can change during
transport. The vehicle may not be secured
sufficiently if this happens .

-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al
-special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform 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 System performs in a crash . For example, using tire-rim
combinations not approved by Audi, lowering the
veh icle, chang ing the stiffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should .
Airbag system
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Side airbags
· Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 237 Side a irbag locatio n in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢ fig . 23 7 and the rear back­
rest* facing the doors.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant s itting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used w ith proper ly installed chi ld re­
straints . Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts¢

@ Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on <=>
page 141.
Low-profile tires
App lies to: ve hicles with low -profile tires
Compared to other tire/rim combinat ions, low­
profile tires offer a wider tread surface and a
l arger r im diameter with shorter tire sidewalls.
This results in an agile dr iv ing style. However, it
may reduce the leve l of comfort and increase
road noise when driving on roads in poor condi­
tion .
L ow -profile tires can become damaged more
quickly than standard tires when driving over
l arge bumps, potholes, manhole covers, and
curbs . Therefore, it is particular ly important to
maintain the correct tire pressure<=>
page 335 .
To reduce the risk of damage to the tires and
rims, drive very carefu lly on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. Fo r example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediate ly by
an authorized Audi dealer or authorized Audi
Service Facility .
Lo w-profile tires can wear out faster than stand­
ard tires.
Wheels
Uniform tire quality grading
-Tread wear
-Traction AA ABC
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width <=>
page 326, fig. 266.
For example: Tread wear 200 , Traction AA, Tem­
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled cond it ions on a specified gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as we ll on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual cond it ions of the ir use, however, and
may depa rt significantly from the norm due to
variations in driv ing habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA , A, Band
C. Those grades represent the tire's
ability to stop o n wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c:>,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
